For example: +To build a custom feature in Medusa, you need three main tools: -```ts title="medusa.config.ts" -import { loadEnv, defineConfig } from "@medusajs/framework/utils" +- [Module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md): a package with commerce logic for a single domain. It defines new tables to add to the database, and a class of methods to manage these tables. +- [Workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md): a tool to perform an operation comprising multiple steps with built-in rollback and retry mechanisms. +- [API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md): a REST endpoint that exposes commerce features to clients, such as the admin dashboard or a storefront. The API route executes a workflow that implements the commerce feature using modules. -loadEnv(process.env.NODE_ENV || "development", process.cwd()) - -module.exports = defineConfig({ - projectConfig: { - databaseUrl: process.env.DATABASE_URL, - http: { - storeCors: process.env.STORE_CORS!, - adminCors: process.env.ADMIN_CORS!, - authCors: process.env.AUTH_CORS!, - jwtSecret: process.env.JWT_SECRET || "supersecret", - cookieSecret: process.env.COOKIE_SECRET || "supersecret", - }, - }, -}) - -``` - -The `defineConfig` utility accepts an object having the following properties: - -- [projectConfig](#project-configurations-projectConfig): Essential configurations related to the Medusa application, such as database and CORS configurations. -- [admin](#admin-configurations-admin): Configurations related to the Medusa Admin. -- [modules](#module-configurations-modules): Configurations related to registered modules. -- [plugins](#plugin-configurations-plugins): Configurations related to registered plugins. -- [featureFlags](#feature-flags-featureFlags): Configurations to manage enabled beta features in the Medusa application. - -### Using Environment Variables - -Notice that you use the `loadEnv` utility to load environment variables. Learn more about it in the [Environment Variables chapter](https://docs.medusajs.com/learn/fundamentals/environment-variables/index.html.md). - -By using this utility, you can use environment variables as the values of your configurations. It's highly recommended that you use environment variables for secret values, such as API keys and database credentials, or for values that change based on the environment, such as the application's Cross Origin Resource Sharing (CORS) configurations. - -For example, you can set the `DATABASE_URL` environment variable in your `.env` file: - -```bash -DATABASE_URL=postgres://postgres@localhost/medusa-store -``` - -Then, use the value in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseUrl: process.env.DATABASE_URL, - // ... - }, - // ... -}) -``` +![Diagram showcasing the flow of a custom developed feature](https://res.cloudinary.com/dza7lstvk/image/upload/v1725867628/Medusa%20Book/custom-development_nofvp6.jpg) *** -## Project Configurations (`projectConfig`) +## Next Chapters: Brand Module Example -The `projectConfig` object contains essential configurations related to the Medusa application, such as database and CORS configurations. +The next chapters will guide you to: -### databaseDriverOptions +1. Build a Brand Module that creates a `Brand` data model and provides data-management features. +2. Add a workflow to create a brand. +3. Expose an API route that allows admin users to create a brand using the workflow. -The `projectConfig.databaseDriverOptions` configuration is an object of additional options used to configure the PostgreSQL connection. For example, you can support TLS/SSL connection using this configuration's `ssl` property. -This configuration is useful for production databases, which can be supported by setting the `rejectUnauthorized` attribute of `ssl` object to `false`. During development, it's recommended not to pass the `ssl.rejectUnauthorized` option. +# Customize Medusa Admin Dashboard -#### Example +In the previous chapters, you've customized your Medusa application to [add brands](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md), [expose an API route to create brands](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), and [linked brands to products](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md). -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseDriverOptions: process.env.NODE_ENV !== "development" ? - { connection: { ssl: { rejectUnauthorized: false } } } : {}, - // ... - }, - // ... -}) -``` +After customizing and extending your application with new features, you may need to provide an interface for admin users to utilize these features. The Medusa Admin dashboard is extendable, allowing you to: -When you disable `rejectUnauthorized`, make sure to also add `?ssl_mode=disable` to the end of the [databaseUrl](#databaseUrl) as well. +- Insert components, called [widgets](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md), on existing pages. +- Add new pages, called [UI Routes](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md). -#### Properties - -- connection: (\`object\`) - - - ssl: (\`object\` | \`boolean\`) - - - pool: (\`object\`) - - - min: (\`number\`) - - - max: (\`number\`) - - - idleTimeoutMillis: (\`number\`) - - - reapIntervalMillis: (\`number\`) - - - createRetryIntervalMillis: (\`number\`) -- idle\_in\_transaction\_session\_timeout: (\`number\`) - -### databaseLogging - -The `projectConfig.databaseLogging` configuration specifies whether database messages should be logged to the console. It is `false` by default. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseLogging: true, - // ... - }, - // ... -}) -``` - -### databaseName - -The `projectConfig.databaseName` configuration determines the name of the database to connect to. If the name is specified in the [databaseUrl](#databaseUrl) configuration, you don't have to use this configuration. - -After setting the database credentials, you can create and setup the database using the [db:setup](https://docs.medusajs.com/resources/medusa-cli/commands/db#dbsetup/index.html.md) command of the Medusa CLI. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseName: process.env.DATABASE_NAME || - "medusa-store", - // ... - }, - // ... -}) -``` - -### databaseSchema - -The `projectConfig.databaseSchema` configuration specifies the PostgreSQL database schema to connect to, which is `public` by default. Use this configuration only if you want to connect to a different schema. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseSchema: process.env.DATABASE_SCHEMA || - "custom", - // ... - }, - // ... -}) -``` - -### databaseUrl - -The `projectConfig.databaseUrl` configuration specifies the PostgreSQL connection URL of the database to connect to. Its format is: - -```bash -postgres://[user][:password]@[host][:port]/[dbname] -``` - -Where: - -- `[user]`: (required) your PostgreSQL username. If not specified, the system's username is used by default. The database user that you use must have create privileges. If you're using the `postgres` superuser, then it should have these privileges by default. Otherwise, make sure to grant your user create privileges. You can learn how to do that in [PostgreSQL's documentation](https://www.postgresql.org/docs/current/ddl-priv.html). -- `[:password]`: an optional password for the user. When provided, make sure to put `:` before the password. -- `[host]`: (required) your PostgreSQL host. When run locally, it should be `localhost`. -- `[:port]`: an optional port that the PostgreSQL server is listening on. By default, it's `5432`. When provided, make sure to put `:` before the port. -- `[dbname]`: the name of the database. If not set, then you must provide the database name in the [databaseName](#databasename) configuration. - -You can learn more about the connection URL format in [PostgreSQL’s documentation](https://www.postgresql.org/docs/current/libpq-connect.html). - -After setting the database URL, you can create and setup the database using the [db:setup](https://docs.medusajs.com/resources/medusa-cli/commands/db#dbsetup/index.html.md) command of the Medusa CLI. - -#### Example - -For example, set the following database URL in your environment variables: - -```bash -DATABASE_URL=postgres://postgres@localhost/medusa-store -``` - -Then, use the value in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - databaseUrl: process.env.DATABASE_URL, - // ... - }, - // ... -}) -``` - -### http - -The `http` configures the application's http-specific settings, such as the JWT secret, CORS configurations, and more. - -#### http.jwtSecret - -The `projectConfig.http.jwtSecret` configuration is a random string used to create authentication tokens in the HTTP layer. This configuration is not required in development, but must be set in production. - -In a development environment, if this option is not set the default value is `supersecret`. However, in production, if this configuration is not set, an error is thrown and the application crashes. This is to ensure that you set a secure value for the JWT secret in production. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - jwtSecret: process.env.JWT_SECRET || "supersecret", - }, - // ... - }, - // ... -}) -``` - -#### http.jwtExpiresIn - -The `projectConfig.http.jwtExpiresIn` configuration specifies the expiration time for the JWT token. Its value format is based off the [ms package](https://github.com/vercel/ms). - -If not provided, the default value is `1d`. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - jwtExpiresIn: process.env.JWT_EXPIRES_IN || "2d", - }, - // ... - }, - // ... -}) -``` - -#### http.cookieSecret - -The `projectConfig.http.cookieSecret` configuration is a random string used to sign cookies in the HTTP layer. This configuration is not required in development, but must be set in production. - -In a development environment, if this option is not set the default value is `supersecret`. However, in production, if this configuration is not set, an error is thrown and the application crashes. This is to ensure that you set a secure value for the cookie secret in production. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - cookieSecret: process.env.COOKIE_SECRET || "supersecret", - }, - // ... - }, - // ... -}) -``` - -#### http.authCors - -The `projectConfig.http.authCors` configuration specifies the accepted URLs or patterns for API routes starting with `/auth`. It can either be one accepted origin, or a comma-separated list of accepted origins. - -Every origin in that list must either be: - -- A full URL. For example, `http://localhost:7001`. The URL must not end with a backslash; -- Or a regular expression pattern that can match more than one origin. For example, `.example.com`. The regex pattern that Medusa tests for is `^([\/~@;%#'])(.*?)\1([gimsuy]*)$`. - -Since the `/auth` routes are used for authentication for both store and admin routes, it's recommended to set this configuration's value to a combination of the [storeCors](#httpstoreCors) and [adminCors](#httpadminCors) configurations. - -Some example values of common use cases: - -```bash -# Allow different ports locally starting with 700 -AUTH_CORS=/http:\/\/localhost:700\d+$/ - -# Allow any origin ending with vercel.app. For example, admin.vercel.app -AUTH_CORS=/vercel\.app$/ - -# Allow all HTTP requests -AUTH_CORS=/http:\/\/.+/ -``` - -Then, set the configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - authCors: process.env.AUTH_CORS, - }, - // ... - }, - // ... -}) -``` - -If you’re adding the value directly within `medusa-config.ts`, make sure to add an extra escaping `/` for every backslash in the pattern. For example: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - authCors: "/http:\\/\\/localhost:700\\d+$/", - }, - // ... - }, - // ... -}) -``` - -#### http.storeCors - -The `projectConfig.http.storeCors` configuration specifies the accepted URLs or patterns for API routes starting with `/store`. It can either be one accepted origin, or a comma-separated list of accepted origins. - -Every origin in that list must either be: - -- A full URL. For example, `http://localhost:7001`. The URL must not end with a backslash; -- Or a regular expression pattern that can match more than one origin. For example, `.example.com`. The regex pattern that Medusa tests for is `^([\/~@;%#'])(.*?)\1([gimsuy]*)$`. - -Some example values of common use cases: - -```bash -# Allow different ports locally starting with 800 -STORE_CORS=/http:\/\/localhost:800\d+$/ - -# Allow any origin ending with vercel.app. For example, storefront.vercel.app -STORE_CORS=/vercel\.app$/ - -# Allow all HTTP requests -STORE_CORS=/http:\/\/.+/ -``` - -Then, set the configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - storeCors: process.env.STORE_CORS, - }, - // ... - }, - // ... -}) -``` - -If you’re adding the value directly within `medusa-config.ts`, make sure to add an extra escaping `/` for every backslash in the pattern.

It can either be one accepted origin, or a comma-separated list of accepted origins. - -Every origin in that list must either be: - -- A full URL. For example, `http://localhost:7001`. The URL must not end with a backslash; -- Or a regular expression pattern that can match more than one origin. For example, `.example.com`. The regex pattern that Medusa tests for is `^([\/~@;%#'])(.*?)\1([gimsuy]*)$`. - -Some example values of common use cases: - -```bash -# Allow different ports locally starting with 700 -ADMIN_CORS=/http:\/\/localhost:700\d+$/ - -# Allow any origin ending with vercel.app. For example, admin.vercel.app -ADMIN_CORS=/vercel\.app$/ - -# Allow all HTTP requests -ADMIN_CORS=/http:\/\/.+/ -``` - -Then, set the configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - adminCors: process.env.ADMIN_CORS, - }, - // ... - }, - // ... -}) -``` - -If you’re adding the value directly within `medusa-config.ts`, make sure to add an extra escaping `/` for every backslash in the pattern. For example: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - adminCors: "/vercel\\.app$/", - }, - // ... - }, - // ... -}) -``` - -#### http.compression - -The `projectConfig.http.compression` configuration modifies the HTTP compression settings at the application layer. If you have access to the HTTP server, the recommended approach would be to enable it there. However, some platforms don't offer access to the HTTP layer and in those cases, this is a good alternative. - -If you enable HTTP compression and you want to disable it for specific API Routes, you can pass in the request header `"x-no-compression": true`. Learn more in the [API Reference](https://docs.medusajs.com/api/store#http-compression). - -For example: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - compression: { - enabled: true, - level: 6, - memLevel: 8, - threshold: 1024, - }, - }, - // ... - }, - // ... -}) -``` - -This configuation is an object that accepts the following properties: - -- enabled: (\`boolean\`) -- level: (\`number\`) The level of zlib compression to apply to responses. A higher level will result in better compression but will take longer to complete. A lower level will result in less compression but will be much faster. -- memLevel: (\`number\`) How much memory should be allocated to the internal compression state. It value is between \`1\` (minimum level) and \`9\` (maximum level). -- threshold: (\`number\` | \`string\`) The minimum response body size that compression is applied on. Its value can be the number of bytes or any string accepted by the \[bytes]\(https://www.npmjs.com/package/bytes) package. - -#### http.authMethodsPerActor - -The `projectConfig.http.authMethodsPerActor` configuration specifies the supported authentication providers per actor type (such as `user`, `customer`, or any custom actor). - -For example, you can allow Google login for `customers`, and allow email/password logins for `users` in the admin. - -`authMethodsPerActor` is a an object whose key is the actor type (for example, `user`), and the value is an array of supported auth provider IDs (for example, `emailpass`). - -Learn more about actor types in the [Auth Identity and Actor Type documentation](https://docs.medusajs.com/resources/commerce-modules/auth/auth-identity-and-actor-types/index.html.md). - -For example: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - authMethodsPerActor: { - user: ["emailpass"], - customer: ["emailpass", "google"], - }, - }, - // ... - }, - // ... -}) -``` - -The above configurations allow admin users to login using email/password, and customers to login using email/password and Google. - -#### http.restrictedFields - -The `projectConfig.http.restrictedFields` configuration specifies the fields that can't be selected in API routes (using the `fields` query parameter) unless they're allowed in the [request's Query configurations](https://docs.medusajs.com/learn/fundamentals/module-links/query#request-query-configurations/index.html.md). This is useful to restrict sensitive fields from being exposed in the API. - -For example, you can restrict selecting customers in store API routes: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - restrictedFields: { - store: ["customer", "customers"], - }, - }, - // ... - }, - // ... -}) -``` - -The `restrictedFields` configuration accepts the following properties: - -- store: (\`string\[]\`) - -### redisOptions - -The `projectConfig.redisOptions` configuration defines options to pass to `ioredis`, which creates the Redis connection used to store the Medusa server session. Refer to [ioredis’s RedisOptions documentation](https://redis.github.io/ioredis/index.html#RedisOptions) -for the list of available options. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - redisOptions: { - connectionName: process.env.REDIS_CONNECTION_NAME || - "medusa", - }, - // ... - }, - // ... -}) -``` - -### redisPrefix - -The `projectConfig.redisPrefix` configuration defines a prefix on all keys stored in Redis for the Medusa server session. The default value is `sess:`. - -The value of this configuration is prepended to `sess:`. For example, if you set it to `medusa:`, then a key stored in Redis is prefixed by `medusa:sess`. - -This configuration is not used for modules that also connect to Redis, such as the [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md). - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - redisPrefix: process.env.REDIS_URL || "medusa:", - // ... - }, - // ... -}) -``` - -### redisUrl - -The `projectConfig.redisUrl` configuration specifies the connection URL to Redis to store the Medusa server session. When specified, the Medusa server uses Redis to store the session data. Otherwie, the session data is stored in-memory. - -This configuration is not used for modules that also connect to Redis, such as the [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md). You'll have to configure the Redis connection for those modules separately. - -You must first have Redis installed. You can refer to [Redis's installation guide](https://redis.io/docs/getting-started/installation/). - -The Redis connection URL has the following format: - -```bash -redis[s]://[[username][:password]@][host][:port][/db-number] -``` - -Where: - -- `redis[s]`: the protocol used to connect to Redis. Use `rediss` for a secure connection. -- `[[username][:password]@]`: an optional username and password for the Redis server. -- `[host]`: the host of the Redis server. When run locally, it should be `localhost`. -- `[:port]`: an optional port that the Redis server is listening on. By default, it's `6379`. -- `[/db-number]`: an optional database number to connect to. By default, it's `0`. - -For a local Redis installation, the connection URL should be `redis://localhost:6379` unless you’ve made any changes to the Redis configuration during installation. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - redisUrl: process.env.REDIS_URL || - "redis://localhost:6379", - // ... - }, - // ... -}) -``` - -### sessionOptions - -The `projectConfig.sessionOptions` configuration defines additional options to pass to [express-session](https://www.npmjs.com/package/express-session), which is used to store the Medusa server session. - -This configuration is not used for modules that also connect to Redis, such as the [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md). - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - sessionOptions: { - name: process.env.SESSION_NAME || "custom", - }, - // ... - }, - // ... -}) -``` - -#### Properties - -- name: (\`string\`) -- resave: (\`boolean\`) -- rolling: (\`boolean\`) -- saveUninitialized: (\`boolean\`) -- secret: (\`string\`) The secret to sign the session ID cookie. By default, the value of \[http.cookieSecret]\(#httpcookieSecret) is used. Refer to \[express-session’s documentation]\(https://www.npmjs.com/package/express-session#secret) for details. -- ttl: (\`number\`) The time-to-live (TTL) of the session ID cookie in milliseconds. It is used when calculating the \`Expires\` \`Set-Cookie\` attribute of cookies. Refer to \[express-session’s documentation]\(https://www.npmjs.com/package/express-session#cookie) for more details. - -### workerMode - -The `projectConfig.workerMode` configuration specifies the worker mode of the Medusa application. You can learn more about it in the [Worker Mode chapter](https://docs.medusajs.com/learn/production/worker-mode/index.html.md). - -The value for this configuration can be one of the following: - -- `shared`: run the application in a single process, meaning the worker and server run in the same process. -- `worker`: run the a worker process only. -- `server`: run the application server only. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - workerMode: process.env.WORKER_MODE || "shared", - // ... - }, - // ... -}) -``` +From these customizations, you can send requests to custom API routes, allowing admin users to manage custom resources on the dashboard *** -## Admin Configurations (`admin`) +## Next Chapters: View Brands in Dashboard -The `admin` object contains configurations related to the Medusa Admin. +In the next chapters, you'll continue with the brands example to: -### backendUrl +- Add a new section to the product details page that shows the product's brand. +- Add a new page in the dashboard that shows all brands in the store. -The `admin.backendUrl` configuration specifies the URL of the Medusa application. Its default value is the browser origin. This is useful to set when running the admin on a separate domain. -#### Example +# Customizations Next Steps: Learn the Fundamentals -```ts title="medusa-config.ts" -module.exports = defineConfig({ - admin: { - backendUrl: process.env.MEDUSA_BACKEND_URL || - "http://localhost:9000", - }, - // ... -}) -``` +The previous guides introduced Medusa's different concepts and how you can use them to customize Medusa for a realistic use case, You added brands to your application, linked them to products, customized the admin dashboard, and integrated a third-party CMS. -### disable +The next chapters will cover each of these concepts in depth, with the different ways you can use them, their options or configurations, and more advanced features that weren't covered in the previous guides. While you can start building with Medusa, it's highly recommended to follow the next chapters for a better understanding of Medusa's fundamentals. -The `admin.disable` configuration specifies whether to disable the Medusa Admin. If disabled, the Medusa Admin will not be compiled and you can't access it at `/app` path of your application. The default value is `false`. +## Useful Guides -#### Example +The following guides and references are useful for your development journey: -```ts title="medusa-config.ts" -module.exports = defineConfig({ - admin: { - disable: process.env.ADMIN_DISABLED === "true" || - false, - }, - // ... -}) -``` - -### path - -The `admin.path` configuration indicates the path to the admin dashboard, which is `/app` by default. The value must start with `/` and can't end with a `/`. - -The value cannot be one of the reserved paths: - -- `/admin` -- `/store` -- `/auth` -- `/` - -When using Docker, make sure that the root path of the Docker image isn't the same as the admin's path. For example, if the Docker image's root path is `/app`, change -the value of the `admin.path` configuration, since it's `/app` by default. - -#### Example - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - admin: { - path: process.env.ADMIN_PATH || `/app`, - }, - // ... -}) -``` - -### storefrontUrl - -The `admin.storefrontUrl` configuration specifies the URL of the Medusa storefront application. This URL is used as a prefix to some links in the admin that require performing actions in the storefront. - -For example, this URL is used as a prefix to shareable payment links for orders with outstanding amounts. - -#### Example - -```js title="medusa-config.js" -module.exports = defineConfig({ - admin: { - storefrontUrl: process.env.MEDUSA_STOREFRONT_URL || - "http://localhost:8000", - }, - // ... -}) -``` - -### vite - -The `admin.vite` configration specifies Vite configurations for the Medusa Admin. Its value is a function that receives the default Vite configuration and returns the modified configuration. The default value is `undefined`. - -Learn about configurations you can pass to Vite in [Vite's documentation](https://vite.dev/config/). - -#### Example - -For example, if you're using a third-party library that isn't ESM-compatible, add it to Vite's `optimizeDeps` configuration: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - admin: { - vite: () => { - return { - optimizeDeps: { - include: ["qs"], - }, - } - }, - }, - // ... -}) -``` +3.

Medusa's commerce and Infrastructure Modules are configured by default. So, you only need to pass your custom modules, or override the default configurations of the existing modules. +In the [Recipes](https://docs.medusajs.com/resources/recipes/index.html.md) documentation, you'll also find step-by-step guides for different use cases, such as building a marketplace, digital products, and more. -`modules` is an array of objects for the modules to register. Each object has the following properties: -1. `resolve`: a string indicating the path to the module, or the module's NPM package name. For example, `./src/modules/my-module`. -2. `options`: (optional) an object indicating the [options to pass to the module](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). This object is specific to the module and its configurations. For example, your module may require an API key option, which you can pass in this object. +# Re-Use Customizations with Plugins -For modules that are part of a plugin, learn about registering them in the [Register Modules in Plugins](#register-modules-in-plugins) section. +In the previous chapters, you've learned important concepts related to creating modules, implementing commerce features in workflows, exposing those features in API routes, customizing the Medusa Admin dashboard with Admin Extensions, and integrating third-party systems. -### Example +You've implemented the brands example within a single Medusa application. However, this approach is not scalable when you want to reuse your customizations across multiple projects. -To register a custom module: +To reuse your customizations across multiple Medusa applications, such as implementing brands in different projects, you can create a plugin. A plugin is an NPM package that encapsulates your customizations and can be installed in any Medusa application. Plugins can include modules, workflows, API routes, Admin Extensions, and more. -```ts title="medusa-config.ts" -module.exports = defineConfig({ - modules: [ - { - resolve: "./src/modules/cms", - options: { - apiKey: process.env.CMS_API_KEY, - }, - }, - ], - // ... -}) -``` +![Diagram showcasing how the Brand Plugin would add its resources to any application it's installed in](https://res.cloudinary.com/dza7lstvk/image/upload/v1737540091/Medusa%20Book/brand-plugin_bk9zi9.jpg) -You can also override the default configurations of Medusa's modules. For example, to add a Notification Module Provider to the Notification Module: +Medusa provides the tooling to create a plugin package, test it in a local Medusa application, and publish it to NPM. -```ts title="medusa-config.ts" -module.exports = defineConfig({ - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - // default provider - { - resolve: "@medusajs/medusa/notification-local", - id: "local", - options: { - name: "Local Notification Provider", - channels: ["feed"], - }, - }, - // custom provider - { - resolve: "./src/modules/my-notification", - id: "my-notification", - options: { - channels: ["email"], - // provider options... - }, - }, - ], - }, - }, - ], - // ... -}) -``` +To learn more about plugins and how to create them, refer to [this chapter](https://docs.medusajs.com/learn/fundamentals/plugins/index.html.md). + + +# Integrate Third-Party Systems + +Commerce applications often connect to third-party systems that provide additional or specialized features. For example, you may integrate a Content-Management System (CMS) for rich content features, a payment provider to process credit-card payments, and a notification service to send emails. + +The Medusa Framework facilitates integrating these systems and orchestrating operations across them, saving you the effort of managing them yourself. You won't find those capabilities in other commerce platforms that in these scenarios become a bottleneck to building customizations and iterating quickly. + +In Medusa, you integrate a third-party system by: + +1. Creating a module whose service provides the methods to connect to and perform operations in the third-party system. +2. Building workflows that complete tasks spanning across systems. You use the module that integrates a third-party system in the workflow's steps. +3. Executing the workflows you built in an [API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md), at a scheduled time, or when an event is emitted. *** -## Plugin Configurations (`plugins`) +## Next Chapters: Sync Brands Example -The `plugins` configuration allows you to register and configure the [plugins](https://docs.medusajs.com/learn/fundamentals/plugins/index.html.md) registered in the Medusa application. Plugins include re-usable Medusa customizations, such as modules, workflows, API routes, and more. +In the previous chapters, you've [added brands](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) to your Medusa application. In the next chapters, you will: -Aside from installing the plugin with NPM, you must also register it in the `medusa.config.ts` file. +1. Integrate a dummy third-party CMS in the Brand Module. +2. Sync brands to the CMS when a brand is created. +3. Sync brands from the CMS at a daily schedule. -The `plugins` configuration is an array of objects for the plugins to register. Each object has the following properties: -- A string, which is the name of the plugin's package as specified in the plugin's `package.json` file. This is useful if the plugin doesn't require any options. -- An object having the following properties: - - `resolve`: The name of the plugin's package as specified in the plugin's `package.json` file. - - `options`: An object that includes [options to be passed to the modules](https://docs.medusajs.com/learn/fundamentals/modules/options#pass-options-to-a-module-in-a-plugin/index.html.md) within the plugin. +# Extend Core Commerce Features -### Example +In the upcoming chapters, you'll learn about the concepts and tools to extend Medusa's core commerce features. -```ts title="medusa-config.ts" -module.exports = { - plugins: [ - `medusa-my-plugin-1`, - { - resolve: `medusa-my-plugin`, - options: { - apiKey: process.env.MY_API_KEY || - `test`, - }, - }, - // ... - ], - // ... -} -``` +In other commerce platforms, you extend core features and models through hacky workarounds that can introduce unexpected issues and side effects across the platform. It also makes your application difficult to maintain and upgrade in the long run. -The above configuration registers two plugins: `medusa-my-plugin-1` and `medusa-my-plugin`. The latter plugin requires an API key option, which is passed in the `options` object. +The Medusa Framework and orchestration tools mitigate these issues while supporting all your customization needs: -### Register Modules in Plugins - -When you register a plugin, its modules are automatically registered in the Medusa application. You don't have to register them manually in the `modules` configuration. - -However, this isn't the case for module providers. If your plugin includes a module provider, you must register it in the `modules` configuration, referencing the module provider's path. - -For example: - -```ts title="medusa-config.ts" -module.exports = { - plugins: [ - `medusa-my-plugin`, - ], - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - // ... - { - resolve: "medusa-my-plugin/providers/my-notification", - id: "my-notification", - options: { - channels: ["email"], - // provider options... - }, - }, - ], - }, - }, - ], - // ... -} -``` +- [Module Links](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md): Link data models of different modules without building direct dependencies, ensuring that the Medusa application integrates your modules without side effects. +- [Workflow Hooks](https://docs.medusajs.com/learn/fundamentals/workflows/workflow-hooks/index.html.md): inject custom functionalities into a workflow at predefined points, called hooks. This allows you to perform custom actions as a part of a core workflow without hacky workarounds. +- [Additional Data in API Routes](https://docs.medusajs.com/learn/fundamentals/api-routes/additional-data/index.html.md): Configure core API routes to accept request parameters relevant to your customizations. These parameters are passed to the underlying workflow's hooks, where you can manage your custom data as part of an existing flow. *** -## Feature Flags (`featureFlags`) +## Next Chapters: Link Brands to Products Example -The `featureFlags` configuration allows you to manage enabled beta features in the Medusa application. +The next chapters explain how to use the tools mentioned above with step-by-step guides. You'll continue with the [brands example from the previous chapters](https://docs.medusajs.com/learn/customization/custom-features/index.html.md) to: -Some features in the Medusa application are guarded by a feature flag. This ensures constant shipping of new features while maintaining the engine’s stability.

For example, you can integrate [Sanity](https://docs.medusajs.com/resources/integrations/guides/sanity/index.html.md) for rich CMS capabilities, or [Odoo](https://docs.medusajs.com/resources/recipes/erp/odoo/index.html.md) to sync your Medusa application with your ERP system. + +You can replace any of the third-party services mentioned above to build your preferred commerce ecosystem. + +![Diagram illustrating the Commerce Modules integration to third-party services](https://res.cloudinary.com/dza7lstvk/image/upload/v1727175357/Medusa%20Book/service-commerce_qcbdsl.jpg) + +### Infrastructure Modules + +[Infrastructure Modules](https://docs.medusajs.com/resources/infrastructure-modules/index.html.md) integrate third-party services and systems that customize Medusa's infrastructure. Medusa has the following Infrastructure Modules: + +- [Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/index.html.md): Caches data that require heavy computation. You can integrate a custom module to handle the caching with services like Memcached, or use the existing [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md). +- [Event Module](https://docs.medusajs.com/resources/infrastructure-modules/event/index.html.md): A pub/sub system that allows you to subscribe to events and trigger them. You can integrate [Redis](https://docs.medusajs.com/resources/infrastructure-modules/event/redis/index.html.md) as the pub/sub system. +- [File Module](https://docs.medusajs.com/resources/infrastructure-modules/file/index.html.md): Manages file uploads and storage, such as upload of product images. You can integrate [AWS S3](https://docs.medusajs.com/resources/infrastructure-modules/file/s3/index.html.md) for file storage. +- [Locking Module](https://docs.medusajs.com/resources/infrastructure-modules/locking/index.html.md): Manages access to shared resources by multiple processes or threads, preventing conflict between processes and ensuring data consistency.

You can integrate [SendGrid](https://docs.medusajs.com/resources/infrastructure-modules/notification/sendgrid/index.html.md) for sending emails. +- [Workflow Engine Module](https://docs.medusajs.com/resources/infrastructure-modules/workflow-engine/index.html.md): Orchestrates workflows that hold the business logic of your application. You can integrate [Redis](https://docs.medusajs.com/resources/infrastructure-modules/workflow-engine/redis/index.html.md) to orchestrate workflows. + +All of the third-party services mentioned above can be replaced to help you build your preferred architecture and ecosystem. + +![Diagram illustrating the Infrastructure Modules integration to third-party services and systems](https://res.cloudinary.com/dza7lstvk/image/upload/v1727175342/Medusa%20Book/service-arch_ozvryw.jpg) *** -## Logging Configurations +## Full Diagram of Medusa's Architecture -### Log Level +The following diagram illustrates Medusa's architecture including all its layers. -The available log levels, from lowest to highest levels, are: - -1. `silly` (default, meaning messages of all levels are logged) -2. `debug` -3. `info` -4. `warn` -5. `error` - -You can change that by setting the `LOG_LEVEL` environment variable to the minimum level you want to be logged. - -For example: - -```bash -LOG_LEVEL=error -``` - -This logs `error` messages only. - -The environment variable must be set as a system environment variable and not in `.env`. - -### Save Logs in a File - -Aside from showing the logs in the terminal, you can save the logs in a file by setting the `LOG_FILE` environment variable to the path of the file relative to the Medusa server’s root directory. - -For example: - -```bash -LOG_FILE=all.log -``` - -Your logs are now saved in the `all.log` file at the root of your Medusa application. - -The environment variable must be set as a system environment variable and not in `.env`. - -*** - -## Show Log with Progress - -The `Logger` class has an `activity` method used to log a message of level `info`. If the Medusa application is running in a development environment, a spinner starts to show the activity's progress. - -For example: - -```ts title="src/jobs/log-message.ts" -import { MedusaContainer } from "@medusajs/framework/types" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" - -export default async function myCustomJob( - container: MedusaContainer -) { - const logger = container.resolve(ContainerRegistrationKeys.LOGGER) - - const activityId = logger.activity("First log message") - - logger.progress(activityId, `Second log message`) - - logger.success(activityId, "Last log message") -} -``` - -The `activity` method returns the ID of the started activity. This ID can then be passed to one of the following methods of the `Logger` class: - -- `progress`: Log a message of level `info` that indicates progress within that same activity. -- `success`: Log a message of level `info` that indicates that the activity has succeeded. This also ends the associated activity. -- `failure`: Log a message of level `error` that indicates that the activity has failed. This also ends the associated activity. - -If you configured the `LOG_LEVEL` environment variable to a level higher than those associated with the above methods, their messages won’t be logged. - - -# Configure Instrumentation - -In this chapter, you'll learn about observability in Medusa and how to configure instrumentation with OpenTelemetry. - -## Observability with OpenTelemtry - -Medusa uses [OpenTelemetry](https://opentelemetry.io/) for instrumentation and reporting.

Medusa's commerce and Infrastructure Modules are configured by default. So, you only need to pass your custom modules, or override the default configurations of the existing modules. + +`modules` is an array of objects for the modules to register. Each object has the following properties: + +1. `resolve`: a string indicating the path to the module, or the module's NPM package name. For example, `./src/modules/my-module`. +2. `options`: (optional) an object indicating the [options to pass to the module](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). This object is specific to the module and its configurations. For example, your module may require an API key option, which you can pass in this object. + +For modules that are part of a plugin, learn about registering them in the [Register Modules in Plugins](#register-modules-in-plugins) section. + +### Example + +To register a custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + modules: [ + { + resolve: "./src/modules/cms", + options: { + apiKey: process.env.CMS_API_KEY, + }, + }, + ], + // ... +}) +``` + +You can also override the default configurations of Medusa's modules. For example, to add a Notification Module Provider to the Notification Module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + // default provider + { + resolve: "@medusajs/medusa/notification-local", + id: "local", + options: { + name: "Local Notification Provider", + channels: ["feed"], + }, + }, + // custom provider + { + resolve: "./src/modules/my-notification", + id: "my-notification", + options: { + channels: ["email"], + // provider options... + }, + }, + ], + }, + }, + ], + // ... +}) +``` + +*** + +## Plugin Configurations (`plugins`) + +The `plugins` configuration allows you to register and configure the [plugins](https://docs.medusajs.com/learn/fundamentals/plugins/index.html.md) registered in the Medusa application. Plugins include re-usable Medusa customizations, such as modules, workflows, API routes, and more. + +Aside from installing the plugin with NPM, you must also register it in the `medusa.config.ts` file. + +The `plugins` configuration is an array of objects for the plugins to register. Each object has the following properties: + +- A string, which is the name of the plugin's package as specified in the plugin's `package.json` file. This is useful if the plugin doesn't require any options. +- An object having the following properties: + - `resolve`: The name of the plugin's package as specified in the plugin's `package.json` file. + - `options`: An object that includes [options to be passed to the modules](https://docs.medusajs.com/learn/fundamentals/modules/options#pass-options-to-a-module-in-a-plugin/index.html.md) within the plugin. + +### Example + +```ts title="medusa-config.ts" +module.exports = { + plugins: [ + `medusa-my-plugin-1`, + { + resolve: `medusa-my-plugin`, + options: { + apiKey: process.env.MY_API_KEY || + `test`, + }, + }, + // ... + ], + // ... +} +``` + +The above configuration registers two plugins: `medusa-my-plugin-1` and `medusa-my-plugin`. The latter plugin requires an API key option, which is passed in the `options` object. + +### Register Modules in Plugins + +When you register a plugin, its modules are automatically registered in the Medusa application. You don't have to register them manually in the `modules` configuration. + +However, this isn't the case for module providers. If your plugin includes a module provider, you must register it in the `modules` configuration, referencing the module provider's path. + +For example: + +```ts title="medusa-config.ts" +module.exports = { + plugins: [ + `medusa-my-plugin`, + ], + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + // ... + { + resolve: "medusa-my-plugin/providers/my-notification", + id: "my-notification", + options: { + channels: ["email"], + // provider options... + }, + }, + ], + }, + }, + ], + // ... +} +``` + +*** + +## Feature Flags (`featureFlags`) + +The `featureFlags` configuration allows you to manage enabled beta features in the Medusa application. + +Some features in the Medusa application are guarded by a feature flag. This ensures constant shipping of new features while maintaining the engine’s stability. You can enable or disable these features using the `featureFlags` configuration. + +The `featureFlags`'s value is an object whose keys are the names of the feature flags, and their values a boolean indicating whether the feature flag is enabled. + +Only enable feature flags in testing or development environments. Enabling a feature flag may introduce breaking changes or unexpected behavior. + +You can find available feature flags and their key name [here](https://github.com/medusajs/medusa/tree/develop/packages/medusa/src/loaders/feature-flags). + +### Example + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + featureFlags: { + index_engine: true, + // ... + }, + // ... +}) +``` + +After enabling a feature flag, make sure to run migrations, as the feature may introduce database changes: + +```bash +npx medusa db:migrate +``` + + +# Logging + +In this chapter, you’ll learn how to use Medusa’s logging utility. + +## Logger Class + +Medusa provides a `Logger` class with advanced logging functionalities. This includes configuring logging levels or saving logs to a file. + +The Medusa application registers the `Logger` class in the Medusa container and each module's container as `logger`. + +*** + +## How to Log a Message + +Resolve the `logger` using the Medusa container to log a message in your resource. + +For example, create the file `src/jobs/log-message.ts` with the following content: + +```ts title="src/jobs/log-message.ts" highlights={highlights} +import { MedusaContainer } from "@medusajs/framework/types" +import { ContainerRegistrationKeys } from "@medusajs/framework/utils" + +export default async function myCustomJob( + container: MedusaContainer +) { + const logger = container.resolve(ContainerRegistrationKeys.LOGGER) + + logger.info("I'm using the logger!") +} + +export const config = { + name: "test-logger", + // execute every minute + schedule: "* * * * *", +} +``` + +This creates a scheduled job that resolves the `logger` from the Medusa container and uses it to log a message. + +### Test the Scheduled Job + +To test out the above scheduled job, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +After a minute, you'll see the following message as part of the logged messages: + +```text +info: I'm using the logger! +``` + +*** + +## Log Levels + +The `Logger` class has the following methods: + +- `info`: The message is logged with level `info`. +- `warn`: The message is logged with level `warn`. +- `error`: The message is logged with level `error`. +- `debug`: The message is logged with level `debug`. + +Each of these methods accepts a string parameter to log in the terminal with the associated level. + +*** + +## Logging Configurations + +### Log Level + +The available log levels, from lowest to highest levels, are: + +1. `silly` (default, meaning messages of all levels are logged) +2. `debug` +3. `info` +4. `warn` +5. `error` + +You can change that by setting the `LOG_LEVEL` environment variable to the minimum level you want to be logged. + +For example: + +```bash +LOG_LEVEL=error +``` + +This logs `error` messages only. + +The environment variable must be set as a system environment variable and not in `.env`. + +### Save Logs in a File + +Aside from showing the logs in the terminal, you can save the logs in a file by setting the `LOG_FILE` environment variable to the path of the file relative to the Medusa server’s root directory. + +For example: + +```bash +LOG_FILE=all.log +``` + +Your logs are now saved in the `all.log` file at the root of your Medusa application. + +The environment variable must be set as a system environment variable and not in `.env`. + +*** + +## Show Log with Progress + +The `Logger` class has an `activity` method used to log a message of level `info`. If the Medusa application is running in a development environment, a spinner starts to show the activity's progress. + +For example: + +```ts title="src/jobs/log-message.ts" +import { MedusaContainer } from "@medusajs/framework/types" +import { ContainerRegistrationKeys } from "@medusajs/framework/utils" + +export default async function myCustomJob( + container: MedusaContainer +) { + const logger = container.resolve(ContainerRegistrationKeys.LOGGER) + + const activityId = logger.activity("First log message") + + logger.progress(activityId, `Second log message`) + + logger.success(activityId, "Last log message") +} +``` + +The `activity` method returns the ID of the started activity. This ID can then be passed to one of the following methods of the `Logger` class: + +- `progress`: Log a message of level `info` that indicates progress within that same activity. +- `success`: Log a message of level `info` that indicates that the activity has succeeded. This also ends the associated activity. +- `failure`: Log a message of level `error` that indicates that the activity has failed. This also ends the associated activity. + +If you configured the `LOG_LEVEL` environment variable to a level higher than those associated with the above methods, their messages won’t be logged. + + # Medusa Testing Tools In this chapter, you'll learn about Medusa's testing tools and how to install and configure them. @@ -4340,208 +4542,6 @@ Medusa's Testing Framework works for integration tests only.

In order of entry, those are: - -1. API Routes (HTTP): Our API Routes are the typical entry point. The Medusa server is based on Express.js, which handles incoming requests. It can also connect to a Redis database that stores the server session data. -2. Workflows: API Routes consume workflows that hold the opinionated business logic of your application. -3. Modules: Workflows use domain-specific modules for resource management. -4. Data store: Modules query the underlying datastore, which is a PostgreSQL database in common cases. - -These layers of stack can be implemented within [plugins](https://docs.medusajs.com/learn/fundamentals/plugins/index.html.md). - -![This diagram illustrates the entry point of requests into the Medusa application through API routes.

In this chapter, you'll expose an API route that allows admin users to create a brand using the workflow from the previous chapter. + +An API Route is an endpoint that acts as an entry point for other clients to interact with your Medusa customizations, such as the admin dashboard, storefronts, or third-party systems. + +The Medusa core application provides a set of [admin](https://docs.medusajs.com/api/admin) and [store](https://docs.medusajs.com/api/store) API routes out-of-the-box. You can also create custom API routes to expose your custom functionalities. + +### Prerequisites + +- [createBrandWorkflow](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md) + +## 1. Create the API Route + +You create an API route in a `route.{ts,js}` file under a sub-directory of the `src/api` directory. The file exports API Route handler functions for at least one HTTP method (`GET`, `POST`, `DELETE`, etc…). + +Learn more about API routes [in this guide](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md). + +The route's path is the path of `route.{ts,js}` relative to `src/api`. So, to create the API route at `/admin/brands`, create the file `src/api/admin/brands/route.ts` with the following content: + +![Directory structure of the Medusa application after adding the route](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869882/Medusa%20Book/brand-route-dir-overview-2_hjqlnf.jpg) + +```ts title="src/api/admin/brands/route.ts" +import { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { + createBrandWorkflow, +} from "../../../workflows/create-brand" + +type PostAdminCreateBrandType = { + name: string +} + +export const POST = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + const { result } = await createBrandWorkflow(req.scope) + .run({ + input: req.validatedBody, + }) + + res.json({ brand: result }) +} +``` + +You export a route handler function with its name (`POST`) being the HTTP method of the API route you're exposing. + +The function receives two parameters: a `MedusaRequest` object to access request details, and `MedusaResponse` object to return or manipulate the response. The `MedusaRequest` object's `scope` property is the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) that holds Framework tools and custom and core modules' services. + +`MedusaRequest` accepts the request body's type as a type argument. + +In the API route's handler, you execute the `createBrandWorkflow` by invoking it and passing the Medusa container `req.scope` as a parameter, then invoking its `run` method. You pass the workflow's input in the `input` property of the `run` method's parameter. You pass the request body's parameters using the `validatedBody` property of `MedusaRequest`. + +You return a JSON response with the created brand using the `res.json` method. + +*** + +## 2. Create Validation Schema + +The API route you created accepts the brand's name in the request body. So, you'll create a schema used to validate incoming request body parameters. + +Medusa uses [Zod](https://zod.dev/) to create validation schemas. These schemas are then used to validate incoming request bodies or query parameters. + +Learn more about API route validation in [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/validation/index.html.md). + +You create a validation schema in a TypeScript or JavaScript file under a sub-directory of the `src/api` directory. So, create the file `src/api/admin/brands/validators.ts` with the following content: + +![Directory structure of Medusa application after adding validators file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869806/Medusa%20Book/brand-route-dir-overview-1_yfyjss.jpg) + +```ts title="src/api/admin/brands/validators.ts" +import { z } from "zod" + +export const PostAdminCreateBrand = z.object({ + name: z.string(), +}) +``` + +You export a validation schema that expects in the request body an object having a `name` property whose value is a string. + +You can then replace `PostAdminCreateBrandType` in `src/api/admin/brands/route.ts` with the following: + +```ts title="src/api/admin/brands/route.ts" +// ... +import { z } from "zod" +import { PostAdminCreateBrand } from "./validators" + +type PostAdminCreateBrandType = z.infer + +// ... +``` + +*** + +## 3. Add Validation Middleware + +A middleware is a function executed before the route handler when a request is sent to an API Route. It's useful to guard API routes, parse custom request body types, and apply validation on an API route. + +Learn more about middlewares in [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md). + +Medusa provides a `validateAndTransformBody` middleware that accepts a Zod validation schema and returns a response error if a request is sent with body parameters that don't satisfy the validation schema. + +Middlewares are defined in the special file `src/api/middlewares.ts`. So, to add the validation middleware on the API route you created in the previous step, create the file `src/api/middlewares.ts` with the following content: + +![Directory structure of the Medusa application after adding the middleware](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869977/Medusa%20Book/brand-route-dir-overview-3_kcx511.jpg) + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformBody, +} from "@medusajs/framework/http" +import { PostAdminCreateBrand } from "./admin/brands/validators" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/admin/brands", + method: "POST", + middlewares: [ + validateAndTransformBody(PostAdminCreateBrand), + ], + }, + ], +}) +``` + +You define the middlewares using the `defineMiddlewares` function and export its returned value. The function accepts an object having a `routes` property, which is an array of middleware objects. + +In the middleware object, you define three properties: + +- `matcher`: a string or regular expression indicating the API route path to apply the middleware on. You pass the create brand's route `/admin/brand`. +- `method`: The HTTP method to restrict the middleware to, which is `POST`. +- `middlewares`: An array of middlewares to apply on the route. You pass the `validateAndTransformBody` middleware, passing it the Zod schema you created earlier. + +The Medusa application will now validate the body parameters of `POST` requests sent to `/admin/brands` to ensure they match the Zod validation schema. If not, an error is returned in the response specifying the issues to fix in the request body. + +*** + +## Test API Route + +To test out the API route, start the Medusa application with the following command: + +```bash npm2yarn +npm run dev +``` + +Since the `/admin/brands` API route has a `/admin` prefix, it's only accessible by authenticated admin users. + +So, to retrieve an authenticated token of your admin user, send a `POST` request to the `/auth/user/emailpass` API Route: + +```bash +curl -X POST 'http://localhost:9000/auth/user/emailpass' \ +-H 'Content-Type: application/json' \ +--data-raw '{ + "email": "admin@medusa-test.com", + "password": "supersecret" +}' +``` + +Make sure to replace the email and password with your admin user's credentials. + +Don't have an admin user? Refer to [this guide](https://docs.medusajs.com/learn/installation#create-medusa-admin-user/index.html.md). + +Then, send a `POST` request to `/admin/brands`, passing the token received from the previous request in the `Authorization` header: + +```bash +curl -X POST 'http://localhost:9000/admin/brands' \ +-H 'Content-Type: application/json' \ +-H 'Authorization: Bearer {token}' \ +--data '{ + "name": "Acme" +}' +``` + +This returns the created brand in the response: + +```json title="Example Response" +{ + "brand": { + "id": "01J7AX9ES4X113HKY6C681KDZJ", + "name": "Acme", + "created_at": "2024-09-09T08:09:34.244Z", + "updated_at": "2024-09-09T08:09:34.244Z" + } +} +``` + +*** + +## Summary + +By following the previous example chapters, you implemented a custom feature that allows admin users to create a brand. You did that by: + +1. Creating a module that defines and manages a `brand` table in the database. +2. Creating a workflow that uses the module's service to create a brand record, and implements the compensation logic to delete that brand in case an error occurs. +3. Creating an API route that allows admin users to create a brand. + +*** + +## Next Steps: Associate Brand with Product + +Now that you have brands in your Medusa application, you want to associate a brand with a product, which is defined in the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md). + +In the next chapters, you'll learn how to build associations between data models defined in different modules. + + +# Guide: Implement Brand Module + +In this chapter, you'll build a Brand Module that adds a `brand` table to the database and provides data-management features for it. + +A module is a reusable package of functionalities related to a single domain or integration. Medusa comes with multiple pre-built modules for core commerce needs, such as the [Cart Module](https://docs.medusajs.com/resources/commerce-modules/cart/index.html.md) that holds the data models and business logic for cart operations. + +In a module, you create data models and business logic to manage them. In the next chapters, you'll see how you use the module to build commerce features. + +Learn more about modules in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). + +## 1. Create Module Directory + +Modules are created in a sub-directory of `src/modules`. So, start by creating the directory `src/modules/brand` that will hold the Brand Module's files. + +![Directory structure in Medusa project after adding the brand directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868844/Medusa%20Book/brand-dir-overview-1_hxwvgx.jpg) + +*** + +## 2. Create Data Model + +A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. + +Learn more about data models in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#1-create-data-model/index.html.md). + +You create a data model in a TypeScript or JavaScript file under the `models` directory of a module. So, to create a data model that represents a new `brand` table in the database, create the file `src/modules/brand/models/brand.ts` with the following content: + +![Directory structure in module after adding the brand data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868920/Medusa%20Book/brand-dir-overview-2_lexhdl.jpg) + +```ts title="src/modules/brand/models/brand.ts" +import { model } from "@medusajs/framework/utils" + +export const Brand = model.define("brand", { + id: model.id().primaryKey(), + name: model.text(), +}) +``` + +You create a `Brand` data model which has an `id` primary key property, and a `name` text property. + +You define the data model using the `define` method of the DML. It accepts two parameters: + +1. The first one is the name of the data model's table in the database. Use snake-case names. +2. The second is an object, which is the data model's schema. + +Learn about other property types in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties/index.html.md). + +*** + +## 3. Create Module Service + +You perform database operations on your data models in a service, which is a class exported by the module and acts like an interface to its functionalities. + +In this step, you'll create the Brand Module's service that provides methods to manage the `Brand` data model. In the next chapters, you'll use this service when exposing custom features that involve managing brands. + +Learn more about services in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#2-create-service/index.html.md). + +You define a service in a `service.ts` or `service.js` file at the root of your module's directory. So, create the file `src/modules/brand/service.ts` with the following content: + +![Directory structure in module after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868984/Medusa%20Book/brand-dir-overview-3_jo7baj.jpg) + +```ts title="src/modules/brand/service.ts" highlights={serviceHighlights} +import { MedusaService } from "@medusajs/framework/utils" +import { Brand } from "./models/brand" + +class BrandModuleService extends MedusaService({ + Brand, +}) { + +} + +export default BrandModuleService +``` + +The `BrandModuleService` extends a class returned by `MedusaService` from the Modules SDK. This function generates a class with data-management methods for your module's data models. + +The `MedusaService` function receives an object of the module's data models as a parameter, and generates methods to manage those data models. So, the `BrandModuleService` now has methods like `createBrands` and `retrieveBrand` to manage the `Brand` data model. + +You'll use these methods in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). + +Find a reference of all generated methods in [this guide](https://docs.medusajs.com/resources/service-factory-reference/index.html.md). + +*** + +## 4. Export Module Definition + +A module must export a definition that tells Medusa the name of the module and its main service. This definition is exported in an `index.ts` file at the module's root directory. + +So, to export the Brand Module's definition, create the file `src/modules/brand/index.ts` with the following content: + +![Directory structure in module after adding the definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869045/Medusa%20Book/brand-dir-overview-4_nf8ymw.jpg) + +```ts title="src/modules/brand/index.ts" +import { Module } from "@medusajs/framework/utils" +import BrandModuleService from "./service" + +export const BRAND_MODULE = "brand" + +export default Module(BRAND_MODULE, { + service: BrandModuleService, +}) +``` + +You use `Module` from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name (`brand`). You'll use this name when you use this module in other customizations. +2. An object with a required property `service` indicating the module's main service. + +You export `BRAND_MODULE` to reference the module's name more reliably in other customizations. + +*** + +## 5. Add Module to Medusa's Configurations + +To start using your module, you must add it to Medusa's configurations in `medusa-config.ts`. + +The object passed to `defineConfig` in `medusa-config.ts` accepts a `modules` property, whose value is an array of modules to add to the application. So, add the following in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/brand", + }, + ], +}) +``` + +The Brand Module is now added to your Medusa application. You'll start using it in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). + +*** + +## 6. Generate and Run Migrations + +A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations ensure that your module is re-usable and removes friction when working in a team, making it easy to reflect changes across team members' databases. + +Learn more about migrations in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#5-generate-migrations/index.html.md). + +[Medusa's CLI tool](https://docs.medusajs.com/resources/medusa-cli/index.html.md) allows you to generate migration files for your module, then run those migrations to reflect the changes in the database. So, run the following commands in your Medusa application's directory: + +```bash +npx medusa db:generate brand +npx medusa db:migrate +``` + +The `db:generate` command accepts as an argument the name of the module to generate the migrations for, and the `db:migrate` command runs all migrations that haven't been run yet in the Medusa application. + +*** + +## Next Step: Create Brand Workflow + +The Brand Module now creates a `brand` table in the database and provides a class to manage its records. + +In the next chapter, you'll implement the functionality to create a brand in a workflow. You'll then use that workflow in a later chapter to expose an endpoint that allows admin users to create a brand. + + +# Guide: Create Brand Workflow + +This chapter builds on the work from the [previous chapter](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) where you created a Brand Module. + +After adding custom modules to your application, you build commerce features around them using workflows. A workflow is a series of queries and actions, called steps, that complete a task spanning across modules. You construct a workflow similar to a regular function, but it's a special function that allows you to define roll-back logic, retry configurations, and more advanced features. + +The workflow you'll create in this chapter will use the Brand Module's service to implement the feature of creating a brand. In the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll expose an API route that allows admin users to create a brand, and you'll use this workflow in the route's implementation. + +Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). + +### Prerequisites + +- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) + +*** + +## 1. Create createBrandStep + +A workflow consists of a series of steps, each step created in a TypeScript or JavaScript file under the `src/workflows` directory. A step is defined using `createStep` from the Workflows SDK + +The workflow you're creating in this guide has one step to create the brand. So, create the file `src/workflows/create-brand.ts` with the following content: + +![Directory structure in the Medusa project after adding the file for createBrandStep](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869184/Medusa%20Book/brand-workflow-dir-overview-1_fjvf5j.jpg) + +```ts title="src/workflows/create-brand.ts" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { BRAND_MODULE } from "../modules/brand" +import BrandModuleService from "../modules/brand/service" + +export type CreateBrandStepInput = { + name: string +} + +export const createBrandStep = createStep( + "create-brand-step", + async (input: CreateBrandStepInput, { container }) => { + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + const brand = await brandModuleService.createBrands(input) + + return new StepResponse(brand, brand.id) + } +) +``` + +You create a `createBrandStep` using the `createStep` function. It accepts the step's unique name as a first parameter, and the step's function as a second parameter. + +The step function receives two parameters: input passed to the step when it's invoked, and an object of general context and configurations. This object has a `container` property, which is the Medusa container. + +The [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) is a registry of Framework and commerce tools accessible in your customizations, such as a workflow's step. The Medusa application registers the services of core and custom modules in the container, allowing you to resolve and use them. + +So, In the step function, you use the Medusa container to resolve the Brand Module's service and use its generated `createBrands` method, which accepts an object of brands to create. + +Learn more about the generated `create` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/create/index.html.md). + +A step must return an instance of `StepResponse`. Its first parameter is the data returned by the step, and the second is the data passed to the compensation function, which you'll learn about next. + +### Add Compensation Function to Step + +You define for each step a compensation function that's executed when an error occurs in the workflow. The compensation function defines the logic to roll-back the changes made by the step. This ensures your data remains consistent if an error occurs, which is especially useful when you integrate third-party services. + +Learn more about the compensation function in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). + +To add a compensation function to the `createBrandStep`, pass it as a third parameter to `createStep`: + +```ts title="src/workflows/create-brand.ts" +export const createBrandStep = createStep( + // ... + async (id: string, { container }) => { + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + await brandModuleService.deleteBrands(id) + } +) +``` + +The compensation function's first parameter is the brand's ID which you passed as a second parameter to the step function's returned `StepResponse`. It also accepts a context object with a `container` property as a second parameter, similar to the step function. + +In the compensation function, you resolve the Brand Module's service from the Medusa container, then use its generated `deleteBrands` method to delete the brand created by the step. This method accepts the ID of the brand to delete. + +Learn more about the generated `delete` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/delete/index.html.md). + +So, if an error occurs during the workflow's execution, the brand that was created by the step is deleted to maintain data consistency. + +*** + +## 2. Create createBrandWorkflow + +You can now create the workflow that runs the `createBrandStep`. A workflow is created in a TypeScript or JavaScript file under the `src/workflows` directory. In the file, you use `createWorkflow` from the Workflows SDK to create the workflow. + +Add the following content in the same `src/workflows/create-brand.ts` file: + +```ts title="src/workflows/create-brand.ts" +// other imports... +import { + // ... + createWorkflow, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" + +// ... + +type CreateBrandWorkflowInput = { + name: string +} + +export const createBrandWorkflow = createWorkflow( + "create-brand", + (input: CreateBrandWorkflowInput) => { + const brand = createBrandStep(input) + + return new WorkflowResponse(brand) + } +) +``` + +You create the `createBrandWorkflow` using the `createWorkflow` function. This function accepts two parameters: the workflow's unique name, and the workflow's constructor function holding the workflow's implementation. + +The constructor function accepts the workflow's input as a parameter. In the function, you invoke the `createBrandStep` you created in the previous step to create a brand. + +A workflow must return an instance of `WorkflowResponse`. It accepts as a parameter the data to return to the workflow's executor. + +*** + +## Next Steps: Expose Create Brand API Route + +You now have a `createBrandWorkflow` that you can execute to create a brand. + +In the next chapter, you'll add an API route that allows admin users to create a brand. You'll learn how to create the API route, and execute in it the workflow you implemented in this chapter. + + +# Create Brands UI Route in Admin + +In this chapter, you'll add a UI route to the admin dashboard that shows all [brands](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) in a new page. You'll retrieve the brands from the server and display them in a table with pagination. + +### Prerequisites + +- [Brands Module](https://docs.medusajs.com/learn/customization/custom-features/modules/index.html.md) + +## 1. Get Brands API Route + +In a [previous chapter](https://docs.medusajs.com/learn/customization/extend-features/query-linked-records/index.html.md), you learned how to add an API route that retrieves brands and their products using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). You'll expand that API route to support pagination, so that on the admin dashboard you can show the brands in a paginated table. + +Replace or create the `GET` API route at `src/api/admin/brands/route.ts` with the following: + +```ts title="src/api/admin/brands/route.ts" highlights={apiRouteHighlights} +// other imports... +import { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + const query = req.scope.resolve("query") + + const { + data: brands, + metadata: { count, take, skip } = {}, + } = await query.graph({ + entity: "brand", + ...req.queryConfig, + }) + + res.json({ + brands, + count, + limit: take, + offset: skip, + }) +} +``` + +In the API route, you use Query's `graph` method to retrieve the brands. In the method's object parameter, you spread the `queryConfig` property of the request object. This property holds configurations for pagination and retrieved fields. + +The query configurations are combined from default configurations, which you'll add next, and the request's query parameters: + +- `fields`: The fields to retrieve in the brands. +- `limit`: The maximum number of items to retrieve. +- `offset`: The number of items to skip before retrieving the returned items. + +When you pass pagination configurations to the `graph` method, the returned object has the pagination's details in a `metadata` property, whose value is an object having the following properties: + +- `count`: The total count of items. +- `take`: The maximum number of items returned in the `data` array. +- `skip`: The number of items skipped before retrieving the returned items. + +You return in the response the retrieved brands and the pagination configurations. + +Learn more about pagination with Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-pagination/index.html.md). + +*** + +## 2. Add Default Query Configurations + +Next, you'll set the default query configurations of the above API route and allow passing query parameters to change the configurations. + +Medusa provides a `validateAndTransformQuery` middleware that validates the accepted query parameters for a request and sets the default Query configuration. So, in `src/api/middlewares.ts`, add a new middleware configuration object: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformQuery, +} from "@medusajs/framework/http" +import { createFindParams } from "@medusajs/medusa/api/utils/validators" +// other imports... + +export const GetBrandsSchema = createFindParams() + +export default defineMiddlewares({ + routes: [ + // ... + { + matcher: "/admin/brands", + method: "GET", + middlewares: [ + validateAndTransformQuery( + GetBrandsSchema, + { + defaults: [ + "id", + "name", + "products.*", + ], + isList: true, + } + ), + ], + }, + + ], +}) +``` + +You apply the `validateAndTransformQuery` middleware on the `GET /admin/brands` API route. The middleware accepts two parameters: + +- A [Zod](https://zod.dev/) schema that a request's query parameters must satisfy. Medusa provides `createFindParams` that generates a Zod schema with the following properties: + - `fields`: A comma-separated string indicating the fields to retrieve. + - `limit`: The maximum number of items to retrieve. + - `offset`: The number of items to skip before retrieving the returned items. + - `order`: The name of the field to sort the items by. Learn more about sorting in [the API reference](https://docs.medusajs.com/api/admin#sort-order) +- An object of Query configurations having the following properties: + - `defaults`: An array of default fields and relations to retrieve. + - `isList`: Whether the API route returns a list of items. + +By applying the above middleware, you can pass pagination configurations to `GET /admin/brands`, which will return a paginated list of brands. You'll see how it works when you create the UI route. + +Learn more about using the `validateAndTransformQuery` middleware to configure Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query#request-query-configurations/index.html.md). + +*** + +## 3. Initialize JS SDK + +In your custom UI route, you'll retrieve the brands by sending a request to the Medusa server. Medusa has a [JS SDK](https://docs.medusajs.com/resources/js-sdk/index.html.md) that simplifies sending requests to the core API route. + +If you didn't follow the [previous chapter](https://docs.medusajs.com/learn/customization/customize-admin/widget/index.html.md), create the file `src/admin/lib/sdk.ts` with the following content: + +![The directory structure of the Medusa application after adding the file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733414606/Medusa%20Book/brands-admin-dir-overview-1_jleg0t.jpg) + +```ts title="src/admin/lib/sdk.ts" +import Medusa from "@medusajs/js-sdk" + +export const sdk = new Medusa({ + baseUrl: import.meta.env.VITE_BACKEND_URL || "/", + debug: import.meta.env.DEV, + auth: { + type: "session", + }, +}) +``` + +You initialize the SDK passing it the following options: + +- `baseUrl`: The URL to the Medusa server. +- `debug`: Whether to enable logging debug messages. This should only be enabled in development. +- `auth.type`: The authentication method used in the client application, which is `session` in the Medusa Admin dashboard. + +Notice that you use `import.meta.env` to access environment variables in your customizations because the Medusa Admin is built on top of Vite. Learn more in [this chapter](https://docs.medusajs.com/learn/fundamentals/admin/environment-variables/index.html.md). + +You can now use the SDK to send requests to the Medusa server. + +Learn more about the JS SDK and its options in [this reference](https://docs.medusajs.com/resources/js-sdk/index.html.md). + +*** + +## 4. Add a UI Route to Show Brands + +You'll now add the UI route that shows the paginated list of brands. A UI route is a React component created in a `page.tsx` file under a sub-directory of `src/admin/routes`. The file's path relative to src/admin/routes determines its path in the dashboard. + +Learn more about UI routes in [this chapter](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md). + +So, to add the UI route at the `localhost:9000/app/brands` path, create the file `src/admin/routes/brands/page.tsx` with the following content: + +![Directory structure of the Medusa application after adding the UI route.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733472011/Medusa%20Book/brands-admin-dir-overview-3_syytld.jpg) + +```tsx title="src/admin/routes/brands/page.tsx" highlights={uiRouteHighlights} +import { defineRouteConfig } from "@medusajs/admin-sdk" +import { TagSolid } from "@medusajs/icons" +import { + Container, +} from "@medusajs/ui" +import { useQuery } from "@tanstack/react-query" +import { sdk } from "../../lib/sdk" +import { useMemo, useState } from "react" + +const BrandsPage = () => { + // TODO retrieve brands + + return ( + + {/* TODO show brands */} + + ) +} + +export const config = defineRouteConfig({ + label: "Brands", + icon: TagSolid, +}) + +export default BrandsPage +``` + +A route's file must export the React component that will be rendered in the new page. It must be the default export of the file. You can also export configurations that add a link in the sidebar for the UI route. You create these configurations using `defineRouteConfig` from the Admin Extension SDK. + +So far, you only show a container. In admin customizations, use components from the [Medusa UI package](https://docs.medusajs.com/ui/index.html.md) to maintain a consistent user interface and design in the dashboard. + +### Retrieve Brands From API Route + +You'll now update the UI route to retrieve the brands from the API route you added earlier. + +First, add the following type in `src/admin/routes/brands/page.tsx`: + +```tsx title="src/admin/routes/brands/page.tsx" +type Brand = { + id: string + name: string +} +type BrandsResponse = { + brands: Brand[] + count: number + limit: number + offset: number +} +``` + +You define the type for a brand, and the type of expected response from the `GET /admin/brands` API route. + +To display the brands, you'll use Medusa UI's [DataTable](https://docs.medusajs.com/ui/components/data-table/index.html.md) component. So, add the following imports in `src/admin/routes/brands/page.tsx`: + +```tsx title="src/admin/routes/brands/page.tsx" +import { + // ... + Heading, + createDataTableColumnHelper, + DataTable, + DataTablePaginationState, + useDataTable, +} from "@medusajs/ui" +``` + +You import the `DataTable` component and the following utilities: + +- `createDataTableColumnHelper`: A utility to create columns for the data table. +- `DataTablePaginationState`: A type that holds the pagination state of the data table. +- `useDataTable`: A hook to initialize and configure the data table. + +You also import the `Heading` component to show a heading above the data table. + +Next, you'll define the table's columns. Add the following before the `BrandsPage` component: + +```tsx title="src/admin/routes/brands/page.tsx" +const columnHelper = createDataTableColumnHelper() + +const columns = [ + columnHelper.accessor("id", { + header: "ID", + }), + columnHelper.accessor("name", { + header: "Name", + }), +] +``` + +You use the `createDataTableColumnHelper` utility to create columns for the data table. You define two columns for the ID and name of the brands. + +Then, replace the `// TODO retrieve brands` in the component with the following: + +```tsx title="src/admin/routes/brands/page.tsx" highlights={queryHighlights} +const limit = 15 +const [pagination, setPagination] = useState({ + pageSize: limit, + pageIndex: 0, +}) +const offset = useMemo(() => { + return pagination.pageIndex * limit +}, [pagination]) + +const { data, isLoading } = useQuery({ + queryFn: () => sdk.client.fetch(`/admin/brands`, { + query: { + limit, + offset, + }, + }), + queryKey: [["brands", limit, offset]], +}) + +// TODO configure data table +``` + +To enable pagination in the `DataTable` component, you need to define a state variable of type `DataTablePaginationState`. It's an object having the following properties: + +- `pageSize`: The maximum number of items per page. You set it to `15`. +- `pageIndex`: A zero-based index of the current page of items. + +You also define a memoized `offset` value that indicates the number of items to skip before retrieving the current page's items. + +Then, you use `useQuery` from [Tanstack (React) Query](https://tanstack.com/query/latest) to query the Medusa server. Tanstack Query provides features like asynchronous state management and optimized caching. + +Do not install Tanstack Query as that will cause unexpected errors in your development. If you prefer installing it for better auto-completion in your code editor, make sure to install `v5.64.2` as a development dependency. + +In the `queryFn` function that executes the query, you use the JS SDK's `client.fetch` method to send a request to your custom API route. The first parameter is the route's path, and the second is an object of request configuration and data. You pass the query parameters in the `query` property. + +This sends a request to the [Get Brands API route](#1-get-brands-api-route), passing the pagination query parameters. Whenever `currentPage` is updated, the `offset` is also updated, which will send a new request to retrieve the brands for the current page. + +### Display Brands Table + +Finally, you'll display the brands in a data table. Replace the `// TODO configure data table` in the component with the following: + +```tsx title="src/admin/routes/brands/page.tsx" +const table = useDataTable({ + columns, + data: data?.brands || [], + getRowId: (row) => row.id, + rowCount: data?.count || 0, + isLoading, + pagination: { + state: pagination, + onPaginationChange: setPagination, + }, +}) +``` + +You use the `useDataTable` hook to initialize and configure the data table. It accepts an object with the following properties: + +- `columns`: The columns of the data table. You created them using the `createDataTableColumnHelper` utility. +- `data`: The brands to display in the table. +- `getRowId`: A function that returns a unique identifier for a row. +- `rowCount`: The total count of items. This is used to determine the number of pages. +- `isLoading`: A boolean indicating whether the data is loading. +- `pagination`: An object to configure pagination. It accepts the following properties: + - `state`: The pagination state of the data table. + - `onPaginationChange`: A function to update the pagination state. + +Then, replace the `{/* TODO show brands */}` in the return statement with the following: + +```tsx title="src/admin/routes/brands/page.tsx" + + + Brands + + + + +``` + +This renders the data table that shows the brands with pagination. The `DataTable` component accepts the `instance` prop, which is the object returned by the `useDataTable` hook. + +*** + +## Test it Out + +To test out the UI route, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, open the admin dashboard at `http://localhost:9000/app`. After you log in, you'll find a new "Brands" sidebar item. Click on it to see the brands in your store. You can also go to `http://localhost:9000/app/brands` to see the page. + +![A new sidebar item is added for the new brands UI route. The UI route shows the table of brands with pagination.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733421074/Medusa%20Book/Screenshot_2024-12-05_at_7.46.52_PM_slcdqd.png) + +*** + +## Summary + +By following the previous chapters, you: + +- Injected a widget into the product details page to show the product's brand. +- Created a UI route in the Medusa Admin that shows the list of brands. + +*** + +## Next Steps: Integrate Third-Party Systems + +Your customizations often span across systems, where you need to retrieve data or perform operations in a third-party system. + +In the next chapters, you'll learn about the concepts that facilitate integrating third-party systems in your application. You'll integrate a dummy third-party system and sync the brands between it and the Medusa application. + + +# Guide: Sync Brands from Medusa to Third-Party + +In the [previous chapter](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md), you created a CMS Module that integrates a dummy third-party system. You can now perform actions using that module within your custom flows. + +In another previous chapter, you [added a workflow](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md) that creates a brand. After integrating the CMS, you want to sync that brand to the third-party system as well. + +Medusa has an event system that emits events when an operation is performed. It allows you to listen to those events and perform an asynchronous action in a function called a [subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). This is useful to perform actions that aren't integral to the original flow, such as syncing data to a third-party system. + +Learn more about Medusa's event system and subscribers in [this chapter](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). + +In this chapter, you'll modify the `createBrandWorkflow` you created before to emit a custom event that indicates a brand was created. Then, you'll listen to that event in a subscriber to sync the brand to the third-party CMS. You'll implement the sync logic within a workflow that you execute in the subscriber. + +### Prerequisites + +- [createBrandWorkflow](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md) +- [CMS Module](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) + +## 1. Emit Event in createBrandWorkflow + +Since syncing the brand to the third-party system isn't integral to creating a brand, you'll emit a custom event indicating that a brand was created. + +Medusa provides an `emitEventStep` that allows you to emit an event in your workflows. So, in the `createBrandWorkflow` defined in `src/workflows/create-brand.ts`, use the `emitEventStep` helper step after the `createBrandStep`: + +```ts title="src/workflows/create-brand.ts" highlights={eventHighlights} +// other imports... +import { + emitEventStep, +} from "@medusajs/medusa/core-flows" + +// ... + +export const createBrandWorkflow = createWorkflow( + "create-brand", + (input: CreateBrandInput) => { + // ... + + emitEventStep({ + eventName: "brand.created", + data: { + id: brand.id, + }, + }) + + return new WorkflowResponse(brand) + } +) +``` + +The `emitEventStep` accepts an object parameter having two properties: + +- `eventName`: The name of the event to emit. You'll use this name later to listen to the event in a subscriber. +- `data`: The data payload to emit with the event. This data is passed to subscribers that listen to the event. You add the brand's ID to the data payload, informing the subscribers which brand was created. + +You'll learn how to handle this event in a later step. + +*** + +## 2. Create Sync to Third-Party System Workflow + +The subscriber that will listen to the `brand.created` event will sync the created brand to the third-party CMS. So, you'll implement the syncing logic in a workflow, then execute the workflow in the subscriber. + +Workflows have a built-in durable execution engine that helps you complete tasks spanning multiple systems. Also, their rollback mechanism ensures that data is consistent across systems even when errors occur during execution. + +Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). + +You'll create a `syncBrandToSystemWorkflow` that has two steps: + +- `useQueryGraphStep`: a step that Medusa provides to retrieve data using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). You'll use this to retrieve the brand's details using its ID. +- `syncBrandToCmsStep`: a step that you'll create to sync the brand to the CMS. + +### syncBrandToCmsStep + +To implement the step that syncs the brand to the CMS, create the file `src/workflows/sync-brands-to-cms.ts` with the following content: + +![Directory structure of the Medusa application after adding the file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493547/Medusa%20Book/cms-dir-overview-4_u5t0ug.jpg) + +```ts title="src/workflows/sync-brands-to-cms.ts" highlights={syncStepHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { InferTypeOf } from "@medusajs/framework/types" +import { Brand } from "../modules/brand/models/brand" +import { CMS_MODULE } from "../modules/cms" +import CmsModuleService from "../modules/cms/service" + +type SyncBrandToCmsStepInput = { + brand: InferTypeOf +} + +const syncBrandToCmsStep = createStep( + "sync-brand-to-cms", + async ({ brand }: SyncBrandToCmsStepInput, { container }) => { + const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) + + await cmsModuleService.createBrand(brand) + + return new StepResponse(null, brand.id) + }, + async (id, { container }) => { + if (!id) { + return + } + + const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) + + await cmsModuleService.deleteBrand(id) + } +) +``` + +You create the `syncBrandToCmsStep` that accepts a brand as an input. In the step, you resolve the CMS Module's service from the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) and use its `createBrand` method. This method will create the brand in the third-party CMS. + +You also pass the brand's ID to the step's compensation function. In this function, you delete the brand in the third-party CMS if an error occurs during the workflow's execution. + +Learn more about compensation functions in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). + +### Create Workflow + +You can now create the workflow that uses the above step.

The workflow has the following steps: + +- `useQueryGraphStep`: Retrieve the brand's details using Query. You pass the brand's ID as a filter, and set the `throwIfKeyNotFound` option to true so that the step throws an error if a brand with the specified ID doesn't exist. +- `syncBrandToCmsStep`: Create the brand in the third-party CMS. + +You'll execute this workflow in the subscriber next. + +Learn more about `useQueryGraphStep` in [this reference](https://docs.medusajs.com/resources/references/helper-steps/useQueryGraphStep/index.html.md). + +*** + +## 3. Handle brand.created Event + +You now have a workflow with the logic to sync a brand to the CMS. You need to execute this workflow whenever the `brand.created` event is emitted. So, you'll create a subscriber that listens to and handle the event. + +Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, create the file `src/subscribers/brand-created.ts` with the following content: + +![Directory structure of the Medusa application after adding the subscriber](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493774/Medusa%20Book/cms-dir-overview-5_iqqwvg.jpg) + +```ts title="src/subscribers/brand-created.ts" highlights={subscriberHighlights} +import type { + SubscriberConfig, + SubscriberArgs, +} from "@medusajs/framework" +import { syncBrandToCmsWorkflow } from "../workflows/sync-brands-to-cms" + +export default async function brandCreatedHandler({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await syncBrandToCmsWorkflow(container).run({ + input: data, + }) +} + +export const config: SubscriberConfig = { + event: "brand.created", +} +``` + +A subscriber file must export: + +- The asynchronous function that's executed when the event is emitted.

The component must be the file's default export. +- A configuration object created with `defineWidgetConfig` from the Admin Extension SDK. The function receives an object as a parameter that has a `zone` property, whose value is the zone to inject the widget to. + +Since the widget is injected at the top of the product details page, the widget receives the product's details as a parameter. + +In the widget, you use [Tanstack (React) Query](https://tanstack.com/query/latest) to query the Medusa server. Tanstack Query provides features like asynchronous state management and optimized caching. In the `queryFn` function that executes the query, you use the JS SDK to send a request to the [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid), passing `+brand.*` in the `fields` query parameter to retrieve the product's brand. + +Do not install Tanstack Query as that will cause unexpected errors in your development. If you prefer installing it for better auto-completion in your code editor, make sure to install `v5.64.2` as a development dependency. + +You then render a section that shows the brand's name. In admin customizations, use components from the [Medusa UI package](https://docs.medusajs.com/ui/index.html.md) to maintain a consistent user interface and design in the dashboard. + +*** + +## Test it Out + +To test out your widget, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, open the admin dashboard at `http://localhost:9000/app`.

Create Module Directory + +You'll integrate the third-party system in a new CMS Module.

A service's constructor accepts two parameters: + +1. The module's container. Since a module is [isolated](https://docs.medusajs.com/learn/fundamentals/modules/isolation/index.html.md), it has a [local container](https://docs.medusajs.com/learn/fundamentals/modules/container/index.html.md) different than the Medusa container you use in other customizations. This container holds Framework tools like the [Logger utility](https://docs.medusajs.com/learn/debugging-and-testing/logging/index.html.md) and resources within the module. +2. Options passed to the module when it's later added in Medusa's configurations. These options are useful to pass secret keys or configurations that ensure your module is re-usable across applications. For the CMS Module, you accept the API key to connect to the dummy CMS as an option. + +When integrating a third-party system that has a Node.js SDK or client, you can initialize that client in the constructor to be used in the service's methods. + +### Integration Methods + +Next, you'll add methods that simulate sending requests to a third-party CMS. You'll use these methods later to sync brands from and to the CMS. + +Add the following methods in the `CmsModuleService`: + +```ts title="src/modules/cms/service.ts" highlights={methodsHighlights} +export class CmsModuleService { + // ... + + // a dummy method to simulate sending a request, + // in a realistic scenario, you'd use an SDK, fetch, or axios clients + private async sendRequest(url: string, method: string, data?: any) { + this.logger_.info(`Sending a ${method} request to ${url}.`) + this.logger_.info(`Request Data: ${JSON.stringify(data, null, 2)}`) + this.logger_.info(`API Key: ${JSON.stringify(this.options_.apiKey, null, 2)}`) + } + + async createBrand(brand: Record) { + await this.sendRequest("/brands", "POST", brand) + } + + async deleteBrand(id: string) { + await this.sendRequest(`/brands/${id}`, "DELETE") + } + + async retrieveBrands(): Promise[]> { + await this.sendRequest("/brands", "GET") + + return [] + } +} +``` + +The `sendRequest` method sends requests to the third-party CMS. Since this guide isn't using a real CMS, it only simulates the sending by logging messages in the terminal. + +You also add three methods that use the `sendRequest` method: + +- `createBrand` that creates a brand in the third-party system. +- `deleteBrand` that deletes the brand in the third-party system. +- `retrieveBrands` to retrieve a brand from the third-party system. + +*** + +## 3. Export Module Definition + +After creating the module's service, you'll export the module definition indicating the module's name and service. + +Create the file `src/modules/cms/index.ts` with the following content: + +![Directory structure of the Medusa application after adding the module definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733492991/Medusa%20Book/cms-dir-overview-3_b0byks.jpg) + +```ts title="src/modules/cms/index.ts" +import { Module } from "@medusajs/framework/utils" +import CmsModuleService from "./service" + +export const CMS_MODULE = "cms" + +export default Module(CMS_MODULE, { + service: CmsModuleService, +}) +``` + +You use `Module` from the Modules SDK to export the module's defintion, indicating that the module's name is `cms` and its service is `CmsModuleService`. + +*** + +## 4. Add Module to Medusa's Configurations + +Finally, add the module to the Medusa configurations at `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + // ... + { + resolve: "./src/modules/cms", + options: { + apiKey: process.env.CMS_API_KEY, + }, + }, + ], +}) +``` + +The object passed in `modules` accept an `options` property, whose value is an object of options to pass to the module. These are the options you receive in the `CmsModuleService`'s constructor. + +You can add the `CMS_API_KEY` environment variable to `.env`: + +```bash +CMS_API_KEY=123 +``` + +*** + +## Next Steps: Sync Brand From Medusa to CMS + +You can now use the CMS Module's service to perform actions on the third-party CMS. + +In the next chapter, you'll learn how to emit an event when a brand is created, then handle that event to sync the brand from Medusa to the third-party service. + + +# Guide: Schedule Syncing Brands from Third-Party + +In the previous chapters, you've [integrated a third-party CMS](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) and implemented the logic to [sync created brands](https://docs.medusajs.com/learn/customization/integrate-systems/handle-event/index.html.md) from Medusa to the CMS. + +However, when you integrate a third-party system, you want the data to be in sync between the Medusa application and the system. One way to do so is by automatically syncing the data once a day. + +You can create an action to be automatically executed at a specified interval using scheduled jobs. A scheduled job is an asynchronous function with a specified schedule of when the Medusa application should run it. Scheduled jobs are useful to automate repeated tasks. + +Learn more about scheduled jobs in [this chapter](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md). + +In this chapter, you'll create a scheduled job that triggers syncing the brands from the third-party CMS to Medusa once a day. You'll implement the syncing logic in a workflow, and execute that workflow in the scheduled job. + +### Prerequisites + +- [CMS Module](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) + +*** + +## 1. Implement Syncing Workflow + +You'll start by implementing the syncing logic in a workflow, then execute the workflow later in the scheduled job. + +Workflows have a built-in durable execution engine that helps you complete tasks spanning multiple systems. Also, their rollback mechanism ensures that data is consistent across systems even when errors occur during execution. + +Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). + +This workflow will have three steps: + +1. `retrieveBrandsFromCmsStep` to retrieve the brands from the CMS. +2. `createBrandsStep` to create the brands retrieved in the first step that don't exist in Medusa. +3. `updateBrandsStep` to update the brands retrieved in the first step that exist in Medusa. + +### retrieveBrandsFromCmsStep + +To create the step that retrieves the brands from the third-party CMS, create the file `src/workflows/sync-brands-from-cms.ts` with the following content: + +![Directory structure of the Medusa application after creating the file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733494196/Medusa%20Book/cms-dir-overview-6_z1omsi.jpg) + +```ts title="src/workflows/sync-brands-from-cms.ts" collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import CmsModuleService from "../modules/cms/service" +import { CMS_MODULE } from "../modules/cms" + +const retrieveBrandsFromCmsStep = createStep( + "retrieve-brands-from-cms", + async (_, { container }) => { + const cmsModuleService: CmsModuleService = container.resolve( + CMS_MODULE + ) + + const brands = await cmsModuleService.retrieveBrands() + + return new StepResponse(brands) + } +) +``` + +You create a `retrieveBrandsFromCmsStep` that resolves the CMS Module's service and uses its `retrieveBrands` method to retrieve the brands in the CMS. You return those brands in the step's response. + +### createBrandsStep + +The brands retrieved in the first step may have brands that don't exist in Medusa. So, you'll create a step that creates those brands.

It resolves the [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md)'s service and uses the generated `createBrands` method to create the brands. + +The step passes the created brands to the compensation function, which deletes those brands if an error occurs during the workflow's execution. + +Learn more about compensation functions in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). + +### Update Brands Step + +The brands retrieved in the first step may also have brands that exist in Medusa. So, you'll create a step that updates their details to match that of the CMS. Add the step to the same `src/workflows/sync-brands-from-cms.ts` file: + +```ts title="src/workflows/sync-brands-from-cms.ts" highlights={updateBrandsHighlights} +// ... + +type UpdateBrand = { + id: string + name: string +} + +type UpdateBrandsInput = { + brands: UpdateBrand[] +} + +export const updateBrandsStep = createStep( + "update-brands-step", + async ({ brands }: UpdateBrandsInput, { container }) => { + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + const prevUpdatedBrands = await brandModuleService.listBrands({ + id: brands.map((brand) => brand.id), + }) + + const updatedBrands = await brandModuleService.updateBrands(brands) + + return new StepResponse(updatedBrands, prevUpdatedBrands) + }, + async (prevUpdatedBrands, { container }) => { + if (!prevUpdatedBrands) { + return + } + + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + await brandModuleService.updateBrands(prevUpdatedBrands) + } +) +``` + +The `updateBrandsStep` receives the brands to update in Medusa. In the step, you retrieve the brand's details in Medusa before the update to pass them to the compensation function. You then update the brands using the Brand Module's `updateBrands` generated method. + +In the compensation function, which receives the brand's old data, you revert the update using the same `updateBrands` method. + +### Create Workflow + +Finally, you'll create the workflow that uses the above steps to sync the brands from the CMS to Medusa. Add to the same `src/workflows/sync-brands-from-cms.ts` file the following: + +```ts title="src/workflows/sync-brands-from-cms.ts" +// other imports... +import { + // ... + createWorkflow, + transform, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" + +// ... + +export const syncBrandsFromCmsWorkflow = createWorkflow( + "sync-brands-from-system", + () => { + const brands = retrieveBrandsFromCmsStep() + + // TODO create and update brands + } +) +``` + +In the workflow, you only use the `retrieveBrandsFromCmsStep` for now, which retrieves the brands from the third-party CMS. + +Next, you need to identify which brands must be created or updated. Since workflows are constructed internally and are only evaluated during execution, you can't access values to perform data manipulation directly. Instead, use [transform](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation/index.html.md) from the Workflows SDK that gives you access to the real-time values of the data, allowing you to create new variables using those values. + +Learn more about data manipulation using `transform` in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation/index.html.md). + +So, replace the `TODO` with the following: + +```ts title="src/workflows/sync-brands-from-cms.ts" +const { toCreate, toUpdate } = transform( + { + brands, + }, + (data) => { + const toCreate: CreateBrand[] = [] + const toUpdate: UpdateBrand[] = [] + + data.brands.forEach((brand) => { + if (brand.external_id) { + toUpdate.push({ + id: brand.external_id as string, + name: brand.name as string, + }) + } else { + toCreate.push({ + name: brand.name as string, + }) + } + }) + + return { toCreate, toUpdate } + } +) + +// TODO create and update the brands +``` + +`transform` accepts two parameters: + +1. The data to be passed to the function in the second parameter. +2. A function to execute only when the workflow is executed. Its return value can be consumed by the rest of the workflow. + +In `transform`'s function, you loop over the brands array to check which should be created or updated. This logic assumes that a brand in the CMS has an `external_id` property whose value is the brand's ID in Medusa. + +You now have the list of brands to create and update. So, replace the new `TODO` with the following: + +```ts title="src/workflows/sync-brands-from-cms.ts" +const created = createBrandsStep({ brands: toCreate }) +const updated = updateBrandsStep({ brands: toUpdate }) + +return new WorkflowResponse({ + created, + updated, +}) +``` + +You first run the `createBrandsStep` to create the brands that don't exist in Medusa, then the `updateBrandsStep` to update the brands that exist in Medusa. You pass the arrays returned by `transform` as the inputs for the steps. + +Finally, you return an object of the created and updated brands. You'll execute this workflow in the scheduled job next. + +*** + +## 2. Schedule Syncing Task + +You now have the workflow to sync the brands from the CMS to Medusa. Next, you'll create a scheduled job that runs this workflow once a day to ensure the data between Medusa and the CMS are always in sync. + +A scheduled job is created in a TypeScript or JavaScript file under the `src/jobs` directory.

An object having an `additional_data` property, which is the custom data passed in the request body under `additional_data`. The object will also have properties passed from the workflow to the hook, which in this case is the `products` property that holds an array of the created products. +2. An object of properties related to the step's context.

Configure Additional Data Validation + +Now that you've consumed the `productsCreated` hook, you want to configure the `/admin/products` API route that creates a new product to accept a brand ID in its `additional_data` parameter. + +You configure the properties accepted in `additional_data` in the `src/api/middlewares.ts` that exports middleware configurations.

You can retrieve the ID of a shipping profile either from the Medusa Admin, or the [List Shipping Profiles API route](https://docs.medusajs.com/api/admin#shipping-profiles_getshippingprofiles). + +The request creates a product and returns it. + +In the Medusa application's logs, you'll find the message `Linked brand to products`, indicating that the workflow hook handler ran and linked the brand to the products. + +*** + +## Next Steps: Query Linked Brands and Products + +Now that you've extending the create-product flow to link a brand to it, you want to retrieve the brand details of a product. You'll learn how to do so in the next chapter. + + +# Guide: Define Module Link Between Brand and Product + +In this chapter, you'll learn how to define a module link between a brand defined in the [custom Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md), and a product defined in the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md) that's available in your Medusa application out-of-the-box. + +Modules are [isolated](https://docs.medusajs.com/learn/fundamentals/modules/isolation/index.html.md) from other resources, ensuring that they're integrated into the Medusa application without side effects. However, you may need to associate data models of different modules, or you're trying to extend data models from Commerce Modules with custom properties. To do that, you define module links. + +A module link forms an association between two data models of different modules while maintaining module isolation. You can then manage and query linked records of the data models using Medusa's Modules SDK. + +In this chapter, you'll define a module link between the `Brand` data model of the Brand Module, and the `Product` data model of the Product Module. In later chapters, you'll manage and retrieve linked product and brand records. + +Learn more about module links in [this chapters](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md). + +### Prerequisites + +- [Brand Module having a Brand data model](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) + +## 1. Define Link + +Links are defined in a TypeScript or JavaScript file under the `src/links` directory. The file defines and exports the link using `defineLink` from the Modules SDK. + +So, to define a link between the `Product` and `Brand` models, create the file `src/links/product-brand.ts` with the following content: + +![The directory structure of the Medusa application after adding the link.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733329897/Medusa%20Book/brands-link-dir-overview_t1rhlp.jpg) + +```ts title="src/links/product-brand.ts" highlights={highlights} +import BrandModule from "../modules/brand" +import ProductModule from "@medusajs/medusa/product" +import { defineLink } from "@medusajs/framework/utils" + +export default defineLink( + { + linkable: ProductModule.linkable.product, + isList: true, + }, + BrandModule.linkable.brand +) +``` + +You import each module's definition object from the `index.ts` file of the module's directory. Each module object has a special `linkable` property that holds the data models' link configurations. + +The `defineLink` function accepts two parameters of the same type, which is either: + +- The data model's link configuration, which you access from the Module's `linkable` property; +- Or an object that has two properties: + - `linkable`: the data model's link configuration, which you access from the Module's `linkable` property. + - `isList`: A boolean indicating whether many records of the data model can be linked to the other model. + +So, in the above code snippet, you define a link between the `Product` and `Brand` data models. Since a brand can be associated with multiple products, you enable `isList` in the `Product` model's object. + +*** + +## 2. Sync the Link to the Database + +A module link is represented in the database as a table that stores the IDs of linked records. So, after defining the link, run the following command to create the module link's table in the database: + +```bash +npx medusa db:migrate +``` + +This command reflects migrations on the database and syncs module links, which creates a table for the `product-brand` link. + +You can also run the `npx medusa db:sync-links` to just sync module links without running migrations. + +*** + +## Next Steps: Extend Create Product Flow + +In the next chapter, you'll extend Medusa's workflow and API route that create a product to allow associating a brand with a product. You'll also learn how to link brand and product records. + + +# Admin Development Constraints + +This chapter lists some constraints of admin widgets and UI routes. + +## Arrow Functions + +Widget and UI route components must be created as arrow functions. + +```ts highlights={arrowHighlights} +// Don't +function ProductWidget() { + // ... +} + +// Do +const ProductWidget = () => { + // ... +} +``` + +*** + +## Widget Zone + +A widget zone's value must be wrapped in double or single quotes.

So, when you send a request to the [List Products](https://docs.medusajs.com/api/admin#products_getproducts), [Get Product](https://docs.medusajs.com/api/admin#products_getproductsid), or any product-related store or admin routes that accept a `fields` query parameter, you can specify in this parameter to return the product's brands. + +Learn more about using the `fields` query parameter to retrieve custom linked data models in the [Retrieve Custom Linked Data Models from Medusa's API Routes](https://docs.medusajs.com/learn/fundamentals/api-routes/retrieve-custom-links/index.html.md) chapter. + +For example, send the following request to retrieve the list of products with their brands: + +```bash +curl 'http://localhost:9000/admin/products?fields=+brand.*' \ +--header 'Authorization: Bearer {token}' +``` + +Make sure to replace `{token}` with your admin user's authentication token. Learn how to retrieve it in the [API reference](https://docs.medusajs.com/api/store#authentication). + +Any product that is linked to a brand will have a `brand` property in its object: + +```json title="Example Product Object" +{ + "id": "prod_123", + // ... + "brand": { + "id": "01JEB44M61BRM3ARM2RRMK7GJF", + "name": "Acme", + "created_at": "2024-12-05T09:59:08.737Z", + "updated_at": "2024-12-05T09:59:08.737Z", + "deleted_at": null + } +} +``` + +By using the `fields` query parameter, you don't have to re-create existing API routes to get custom data models that you linked to core data models. + +### Limitations: Filtering by Brands in Existing API Routes + +While you can retrieve linked records using the `fields` query parameter of an existing API route, you can't filter by linked records. + +Instead, you'll have to create a custom API route that uses Query to retrieve linked records with filters, as explained in the [Query documentation](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-filters-and-pagination-on-linked-records/index.html.md). + +*** + +## Approach 2: Use Query to Retrieve Linked Records + +You can also retrieve linked records using Query. Query allows you to retrieve data across modules with filters, pagination, and more. You can resolve Query from the Medusa container and use it in your API route or workflow. + +Learn more about Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). + +For example, you can create an API route that retrieves brands and their products. If you followed the [Create Brands API route chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll have the file `src/api/admin/brands/route.ts` with a `POST` API route. Add a new `GET` function to the same file: + +```ts title="src/api/admin/brands/route.ts" highlights={highlights} +// other imports... +import { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + const query = req.scope.resolve("query") + + const { data: brands } = await query.graph({ + entity: "brand", + fields: ["*", "products.*"], + }) + + res.json({ brands }) +} +``` + +This adds a `GET` API route at `/admin/brands`. In the API route, you resolve Query from the Medusa container. Query has a `graph` method that runs a query to retrieve data. It accepts an object having the following properties: + +- `entity`: The data model's name as specified in the first parameter of `model.define`. +- `fields`: An array of properties and relations to retrieve. You can pass: + - A property's name, such as `id`, or `*` for all properties. + - A relation or linked model's name, such as `products` (use the plural name since brands are linked to list of products). You suffix the name with `.*` to retrieve all its properties. + +`graph` returns an object having a `data` property, which is the retrieved brands. You return the brands in the response. + +### Test it Out + +To test the API route out, send a `GET` request to `/admin/brands`: + +```bash +curl 'http://localhost:9000/admin/brands' \ +-H 'Authorization: Bearer {token}' +``` + +Make sure to replace `{token}` with your admin user's authentication token.

Workflow event: an event that's emitted in a workflow after a commerce feature is performed. For example, Medusa emits the `order.placed` event after a cart is completed. -2. Service event: an event that's emitted to track, trace, or debug processes under the hood. For example, you can emit an event with an audit trail. - -### Which Event Type to Use? - -**Workflow events** are the most common event type in development, as most custom features and customizations are built around workflows. - -Some examples of workflow events: - -1. When a user creates a blog post and you're emitting an event to send a newsletter email. -2. When you finish syncing products to a third-party system and you want to notify the admin user of new products added. -3. When a customer purchases a digital product and you want to generate and send it to them. - -You should only go for a **service event** if you're emitting an event for processes under the hood that don't directly affect front-facing features. - -Some examples of service events: - -1. When you're tracing data manipulation and changes, and you want to track every time some custom data is changed. -2. When you're syncing data with a search engine. - -*** - -## Emit Event in a Workflow - -To emit a workflow event, use the `emitEventStep` helper step provided in the `@medusajs/medusa/core-flows` package. - -For example: - -```ts highlights={highlights} -import { - createWorkflow, -} from "@medusajs/framework/workflows-sdk" -import { - emitEventStep, -} from "@medusajs/medusa/core-flows" - -const helloWorldWorkflow = createWorkflow( - "hello-world", - () => { - // ... - - emitEventStep({ - eventName: "custom.created", - data: { - id: "123", - // other data payload - }, - }) - } -) -``` - -The `emitEventStep` accepts an object having the following properties: - -- `eventName`: The event's name. -- `data`: The data payload as an object. You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. - -In this example, you emit the event `custom.created` and pass in the data payload an ID property. - -### Test it Out - -If you execute the workflow, the event is emitted and you can see it in your application's logs. - -Any subscribers listening to the event are executed. - -*** - -## Emit Event in a Service - -To emit a service event: - -1.

You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. - -3. By default, the Event Module's service isn't injected into your module's container. To add it to the container, pass it in the module's registration object in `medusa-config.ts` in the `dependencies` property: - -```ts title="medusa-config.ts" highlights={depsHighlight} -import { Modules } from "@medusajs/framework/utils" - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/blog", - dependencies: [ - Modules.EVENT_BUS, - ], - }, - ], -}) -``` - -The `dependencies` property accepts an array of module registration keys.

one-to-one relation, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. + +For example, assuming you have the [User and Email data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-one-relationship/index.html.md), set an email's user ID as follows: + +```ts highlights={belongsHighlights} +// when creating an email +const email = await helloModuleService.createEmails({ + // other properties... + user_id: "123", +}) + +// when updating an email +const email = await helloModuleService.updateEmails({ + id: "321", + // other properties... + user_id: "123", +}) +``` + +In the example above, you pass the `user_id` property when creating or updating an email to specify the user it belongs to. + +### HasOne Side + +When you create a record of a data model that has one of another, pass the ID of the other data model's record in the

id: "321", + // other properties... + email: "123", +}) +``` + +In the example above, you pass the `email` property when creating or updating a user to specify the email it has. + +*** + +## Manage One-to-Many Relationship + +In a one-to-many relationship, you can only manage the associations from the `belongsTo` side. + +When you create a record of the data model on the `belongsTo` side, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. + +For example, assuming you have the [Product and Store data models

[pivotEntity](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), refer to [this section](#manage-many-to-many-relationship-with-pivotentity) instead. + +### Create Associations + +When you create a record of a data model that has a many-to-many relationship to another data model, pass an array of IDs of the other data model's records in the relation property. + +For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), set the association between products and orders as follows: + +```ts highlights={manyHighlights} +// when creating a product +const product = await helloModuleService.createProducts({ + // other properties... + orders: ["123", "321"], +}) + +// when creating an order +const order = await helloModuleService.createOrders({ + id: "321", + // other properties... + products: ["123", "321"], +}) +``` + +In the example above, you pass the `orders` property when you create a product, and you pass the `products` property when you create an order. + +### Update Associations + +When you use the `update` methods generated by the service factory, you also pass an array of IDs as the relation property's value to add new associated records. + +However, this removes any existing associations to records whose IDs aren't included in the array. + +For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), you update the product's related orders as so: + +```ts +const product = await helloModuleService.updateProducts({ + id: "123", + // other properties... + orders: ["321"], +}) +``` + +If the product was associated with an order, and you don't include that order's ID in the `orders` array, the association between the product and order is removed. + +So, to add a new association without removing existing ones, retrieve the product first to pass its associated orders when updating the product: + +```ts highlights={updateAssociationHighlights} +const product = await helloModuleService.retrieveProduct( + "123", + { + relations: ["orders"], + } +) + +const updatedProduct = await helloModuleService.updateProducts({ + id: product.id, + // other properties... +

Only one of the data models in the relation can define the `pivotTable`, `joinColumn`, and `inverseJoinColumn` configurations, and it's considered the owner data model. The object can accept the following properties: + - `mappedBy`: The name of the relationship property in the other data model. If not set, the property's name is inferred from the associated data model's name. + - `pivotTable`: The name of the pivot table created in the database for the many-to-many relation.

For example, `order_products`. + +The pivot table has a column with the name `{data_model}_id` for each of the data model's tables.

To add extra columns to the created pivot table, you pass a `pivotEntity` option to the `products` relation in `Order` (since `Order` is the owner). The value of `pivotEntity` is a function that returns the data model representing the pivot table. + +The `OrderProduct` model defines, aside from the ID, the following properties: + +- `order`: A relation that indicates this model belongs to the `Order` data model.

A function that returns the associated data model. -2. An object of optional configuration. Only one of the data models in the relation can define the `pivotTable`, `joinColumn`, and `inverseJoinColumn` configurations, and it's considered the owner data model. The object can accept the following properties: - - `mappedBy`: The name of the relationship property in the other data model. If not set, the property's name is inferred from the associated data model's name. - - `pivotTable`: The name of the pivot table created in the database for the many-to-many relation. If not set, the pivot table is inferred by combining the names of the data models' tables in alphabetical order, separating them by `_`, and pluralizing the last name. For example, `order_products`. - - `joinColumn`: The name of the column in the pivot table that points to the owner model's primary key. - - `inverseJoinColumn`: The name of the column in the pivot table that points to the owned model's primary key. - -The `pivotTable`, `joinColumn`, and `inverseJoinColumn` properties are only available after [Medusa v2.0.7](https://github.com/medusajs/medusa/releases/tag/v2.0.7). - -Following [Medusa v2.1.0](https://github.com/medusajs/medusa/releases/tag/v2.1.0), if `pivotTable`, `joinColumn`, and `inverseJoinColumn` aren't specified on either model, the owner is decided based on alphabetical order. So, in the example above, the `Order` data model would be the owner. - -In this example, an order is associated with many products, and a product is associated with many orders. Since the `pivotTable`, `joinColumn`, and `inverseJoinColumn` configurations are defined on the order, it's considered the owner data model. - -### Many-to-Many Relationship in the Database - -When you generate the migrations of data models that have a many-to-many relationship, the migration adds a new pivot table. Its name is either the name you specify in the `pivotTable` configuration or the inferred name combining the names of the data models' tables in alphabetical order, separating them by `_`, and pluralizing the last name. For example, `order_products`. - -The pivot table has a column with the name `{data_model}_id` for each of the data model's tables. It also has foreign keys on each of these columns to their respective tables. - -The pivot table has columns with foreign keys pointing to the primary key of the associated tables. The column's name is either: - -- The value of the `joinColumn` configuration for the owner table, and the `inverseJoinColumn` configuration for the owned table; -- Or the inferred name `{table_name}_id`. - -![Diagram illustrating the relation between order and product records in the database](https://res.cloudinary.com/dza7lstvk/image/upload/v1726734269/Medusa%20Book/many-to-many_fzy5pq.jpg) - -### Many-To-Many with Custom Columns - -To add custom columns to the pivot table between two data models having a many-to-many relationship, you must define a new data model that represents the pivot table. - -For example: - -```ts highlights={manyToManyColumnHighlights} -import { model } from "@medusajs/framework/utils" - -export const Order = model.define("order_test", { - id: model.id().primaryKey(), - products: model.manyToMany(() => Product, { - pivotEntity: () => OrderProduct, - }), -}) - -export const Product = model.define("product_test", { - id: model.id().primaryKey(), - orders: model.manyToMany(() => Order), -}) - -export const OrderProduct = model.define("orders_products", { - id: model.id().primaryKey(), - order: model.belongsTo(() => Order, { - mappedBy: "products", - }), - product: model.belongsTo(() => Product, { - mappedBy: "orders", - }), - metadata: model.json().nullable(), -}) -``` - -The `Order` and `Product` data models have a many-to-many relationship. To add extra columns to the created pivot table, you pass a `pivotEntity` option to the `products` relation in `Order` (since `Order` is the owner). The value of `pivotEntity` is a function that returns the data model representing the pivot table. - -The `OrderProduct` model defines, aside from the ID, the following properties: - -- `order`: A relation that indicates this model belongs to the `Order` data model. You set the `mappedBy` option to the many-to-many relation's name in the `Order` data model. -- `product`: A relation that indicates this model belongs to the `Product` data model. You set the `mappedBy` option to the many-to-many relation's name in the `Product` data model. -- `metadata`: An extra column to add to the pivot table of type `json`. You can add other columns as well to the model. - -*** - -## Set Relationship Name in the Other Model - -The relationship property methods accept as a second parameter an object of options. The `mappedBy` property defines the name of the relationship in the other data model. - -This is useful if the relationship property’s name is different from that of the associated data model. - -As seen in previous examples, the `mappedBy` option is required for the `belongsTo` method. - -For example: - -```ts highlights={relationNameHighlights} -import { model } from "@medusajs/framework/utils" - -const User = model.define("user", { - id: model.id().primaryKey(), - email: model.hasOne(() => Email, { - mappedBy: "owner", - }), -}) - -const Email = model.define("email", { - id: model.id().primaryKey(), - owner: model.belongsTo(() => User, { - mappedBy: "email", - }), -}) -``` - -In this example, you specify in the `User` data model’s relationship property that the name of the relationship in the `Email` data model is `owner`. - -*** - -## Cascades - -When an operation is performed on a data model, such as record deletion, the relationship cascade specifies what related data model records should be affected by it. - -For example, if a store is deleted, its products should also be deleted. - -The `cascades` method used on a data model configures which child records an operation is cascaded to. - -For example: - -```ts highlights={highlights} -import { model } from "@medusajs/framework/utils" - -const Store = model.define("store", { - id: model.id().primaryKey(), - products: model.hasMany(() => Product), -}) -.cascades({ - delete: ["products"], -}) - -const Product = model.define("product", { - id: model.id().primaryKey(), - store: model.belongsTo(() => Store, { - mappedBy: "products", - }), -}) -``` - -The `cascades` method accepts an object. Its key is the operation’s name, such as `delete`. The value is an array of relationship property names that the operation is cascaded to. - -In the example above, when a store is deleted, its associated products are also deleted. - - -# Module Link Direction - -In this chapter, you'll learn about the difference in module link directions, and which to use based on your use case. - -The details in this chapter don't apply to [Read-Only Module Links](https://docs.medusajs.com/learn/fundamentals/module-links/read-only/index.html.md).

Workflow event: an event that's emitted in a workflow after a commerce feature is performed. For example, Medusa emits the `order.placed` event after a cart is completed. +2. Service event: an event that's emitted to track, trace, or debug processes under the hood. For example, you can emit an event with an audit trail. + +### Which Event Type to Use? + +**Workflow events** are the most common event type in development, as most custom features and customizations are built around workflows. + +Some examples of workflow events: + +1. When a user creates a blog post and you're emitting an event to send a newsletter email. +2. When you finish syncing products to a third-party system and you want to notify the admin user of new products added. +3. When a customer purchases a digital product and you want to generate and send it to them. + +You should only go for a **service event** if you're emitting an event for processes under the hood that don't directly affect front-facing features. + +Some examples of service events: + +1. When you're tracing data manipulation and changes, and you want to track every time some custom data is changed. +2. When you're syncing data with a search engine. + +*** + +## Emit Event in a Workflow + +To emit a workflow event, use the `emitEventStep` helper step provided in the `@medusajs/medusa/core-flows` package. + +For example: + +```ts highlights={highlights} +import { + createWorkflow, +} from "@medusajs/framework/workflows-sdk" +import { + emitEventStep, +} from "@medusajs/medusa/core-flows" + +const helloWorldWorkflow = createWorkflow( + "hello-world", + () => { + // ... + + emitEventStep({ + eventName: "custom.created", + data: { + id: "123", + // other data payload + }, + }) + } +) +``` + +The `emitEventStep` accepts an object having the following properties: + +- `eventName`: The event's name. +- `data`: The data payload as an object. You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. + +In this example, you emit the event `custom.created` and pass in the data payload an ID property. + +### Test it Out + +If you execute the workflow, the event is emitted and you can see it in your application's logs. + +Any subscribers listening to the event are executed. + +*** + +## Emit Event in a Service + +To emit a service event: + +1.

Use the event bus service's `emit` method in the service's methods to emit an event: + +```ts title="src/modules/blog/service.ts" highlights={serviceHighlights} +class BlogModuleService { + // ... + performAction() { + // TODO perform action + + this.eventBusService_.emit({ + name: "custom.event", + data: { + id: "123", + // other data payload + }, + }) + } +} +``` + +The method accepts an object having the following properties: + +- `name`: The event's name. +- `data`: The data payload as an object. You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. + +3. By default, the Event Module's service isn't injected into your module's container. To add it to the container, pass it in the module's registration object in `medusa-config.ts` in the `dependencies` property: + +```ts title="medusa-config.ts" highlights={depsHighlight} +import { Modules } from "@medusajs/framework/utils" + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/blog", + dependencies: [ + Modules.EVENT_BUS, + ], + }, + ], +}) +``` + +The `dependencies` property accepts an array of module registration keys. The specified modules' main services are injected into the module's container. + +That's how you can resolve it in your module's main service's constructor. + +### Test it Out + +If you execute the `performAction` method of your service, the event is emitted and you can see it in your application's logs. + +Any subscribers listening to the event are also executed. + + +# Module Link Direction + +In this chapter, you'll learn about the difference in module link directions, and which to use based on your use case. + +The details in this chapter don't apply to [Read-Only Module Links](https://docs.medusajs.com/learn/fundamentals/module-links/read-only/index.html.md).

You pass the request body's parameters using the `validatedBody` property of `MedusaRequest`. - -You return a JSON response with the created brand using the `res.json` method. - -*** - -## 2. Create Validation Schema - -The API route you created accepts the brand's name in the request body. So, you'll create a schema used to validate incoming request body parameters. - -Medusa uses [Zod](https://zod.dev/) to create validation schemas. These schemas are then used to validate incoming request bodies or query parameters. - -Learn more about API route validation in [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/validation/index.html.md). - -You create a validation schema in a TypeScript or JavaScript file under a sub-directory of the `src/api` directory.

So, to add the validation middleware on the API route you created in the previous step, create the file `src/api/middlewares.ts` with the following content: - -![Directory structure of the Medusa application after adding the middleware](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869977/Medusa%20Book/brand-route-dir-overview-3_kcx511.jpg) - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { PostAdminCreateBrand } from "./admin/brands/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/admin/brands", - method: "POST", - middlewares: [ - validateAndTransformBody(PostAdminCreateBrand), - ], - }, - ], -}) -``` - -You define the middlewares using the `defineMiddlewares` function and export its returned value. The function accepts an object having a `routes` property, which is an array of middleware objects. - -In the middleware object, you define three properties: - -- `matcher`: a string or regular expression indicating the API route path to apply the middleware on. You pass the create brand's route `/admin/brand`. -- `method`: The HTTP method to restrict the middleware to, which is `POST`. -- `middlewares`: An array of middlewares to apply on the route. You pass the `validateAndTransformBody` middleware, passing it the Zod schema you created earlier. - -The Medusa application will now validate the body parameters of `POST` requests sent to `/admin/brands` to ensure they match the Zod validation schema. If not, an error is returned in the response specifying the issues to fix in the request body. - -*** - -## Test API Route - -To test out the API route, start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Since the `/admin/brands` API route has a `/admin` prefix, it's only accessible by authenticated admin users. - -So, to retrieve an authenticated token of your admin user, send a `POST` request to the `/auth/user/emailpass` API Route: - -```bash -curl -X POST 'http://localhost:9000/auth/user/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "admin@medusa-test.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password with your admin user's credentials. - -Don't have an admin user? Refer to [this guide](https://docs.medusajs.com/learn/installation#create-medusa-admin-user/index.html.md). - -Then, send a `POST` request to `/admin/brands`, passing the token received from the previous request in the `Authorization` header: - -```bash -curl -X POST 'http://localhost:9000/admin/brands' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "name": "Acme" -}' -``` - -This returns the created brand in the response: - -```json title="Example Response" -{ - "brand": { - "id": "01J7AX9ES4X113HKY6C681KDZJ", - "name": "Acme", - "created_at": "2024-09-09T08:09:34.244Z", - "updated_at": "2024-09-09T08:09:34.244Z" - } -} -``` - -*** - -## Summary - -By following the previous example chapters, you implemented a custom feature that allows admin users to create a brand. You did that by: - -1. Creating a module that defines and manages a `brand` table in the database. -2. Creating a workflow that uses the module's service to create a brand record, and implements the compensation logic to delete that brand in case an error occurs. -3. Creating an API route that allows admin users to create a brand. - -*** - -## Next Steps: Associate Brand with Product - -Now that you have brands in your Medusa application, you want to associate a brand with a product, which is defined in the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md). - -In the next chapters, you'll learn how to build associations between data models defined in different modules. - - -# Create Brands UI Route in Admin - -In this chapter, you'll add a UI route to the admin dashboard that shows all [brands](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) in a new page. You'll retrieve the brands from the server and display them in a table with pagination. - -### Prerequisites - -- [Brands Module](https://docs.medusajs.com/learn/customization/custom-features/modules/index.html.md) - -## 1. Get Brands API Route - -In a [previous chapter](https://docs.medusajs.com/learn/customization/extend-features/query-linked-records/index.html.md), you learned how to add an API route that retrieves brands and their products using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). You'll expand that API route to support pagination, so that on the admin dashboard you can show the brands in a paginated table. - -Replace or create the `GET` API route at `src/api/admin/brands/route.ts` with the following: - -```ts title="src/api/admin/brands/route.ts" highlights={apiRouteHighlights} -// other imports... -import { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const query = req.scope.resolve("query") - - const { - data: brands, - metadata: { count, take, skip } = {}, - } = await query.graph({ - entity: "brand", - ...req.queryConfig, - }) - - res.json({ - brands, - count, - limit: take, - offset: skip, - }) -} -``` - -In the API route, you use Query's `graph` method to retrieve the brands. In the method's object parameter, you spread the `queryConfig` property of the request object. This property holds configurations for pagination and retrieved fields. - -The query configurations are combined from default configurations, which you'll add next, and the request's query parameters: - -- `fields`: The fields to retrieve in the brands. -- `limit`: The maximum number of items to retrieve. -- `offset`: The number of items to skip before retrieving the returned items. - -When you pass pagination configurations to the `graph` method, the returned object has the pagination's details in a `metadata` property, whose value is an object having the following properties: - -- `count`: The total count of items. -- `take`: The maximum number of items returned in the `data` array. -- `skip`: The number of items skipped before retrieving the returned items. - -You return in the response the retrieved brands and the pagination configurations. - -Learn more about pagination with Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-pagination/index.html.md). - -*** - -## 2. Add Default Query Configurations - -Next, you'll set the default query configurations of the above API route and allow passing query parameters to change the configurations. - -Medusa provides a `validateAndTransformQuery` middleware that validates the accepted query parameters for a request and sets the default Query configuration. So, in `src/api/middlewares.ts`, add a new middleware configuration object: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformQuery, -} from "@medusajs/framework/http" -import { createFindParams } from "@medusajs/medusa/api/utils/validators" -// other imports... - -export const GetBrandsSchema = createFindParams() - -export default defineMiddlewares({ - routes: [ - // ... - { - matcher: "/admin/brands", - method: "GET", - middlewares: [ - validateAndTransformQuery( - GetBrandsSchema, - { - defaults: [ - "id", - "name", - "products.*", - ], - isList: true, - } - ), - ], - }, - - ], -}) -``` - -You apply the `validateAndTransformQuery` middleware on the `GET /admin/brands` API route. The middleware accepts two parameters: - -- A [Zod](https://zod.dev/) schema that a request's query parameters must satisfy. Medusa provides `createFindParams` that generates a Zod schema with the following properties: - - `fields`: A comma-separated string indicating the fields to retrieve. - - `limit`: The maximum number of items to retrieve. - - `offset`: The number of items to skip before retrieving the returned items. - - `order`: The name of the field to sort the items by. Learn more about sorting in [the API reference](https://docs.medusajs.com/api/admin#sort-order) -- An object of Query configurations having the following properties: - - `defaults`: An array of default fields and relations to retrieve. - - `isList`: Whether the API route returns a list of items. - -By applying the above middleware, you can pass pagination configurations to `GET /admin/brands`, which will return a paginated list of brands. You'll see how it works when you create the UI route. - -Learn more about using the `validateAndTransformQuery` middleware to configure Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query#request-query-configurations/index.html.md). - -*** - -## 3. Initialize JS SDK - -In your custom UI route, you'll retrieve the brands by sending a request to the Medusa server. Medusa has a [JS SDK](https://docs.medusajs.com/resources/js-sdk/index.html.md) that simplifies sending requests to the core API route. - -If you didn't follow the [previous chapter](https://docs.medusajs.com/learn/customization/customize-admin/widget/index.html.md), create the file `src/admin/lib/sdk.ts` with the following content: - -![The directory structure of the Medusa application after adding the file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733414606/Medusa%20Book/brands-admin-dir-overview-1_jleg0t.jpg) - -```ts title="src/admin/lib/sdk.ts" -import Medusa from "@medusajs/js-sdk" - -export const sdk = new Medusa({ - baseUrl: import.meta.env.VITE_BACKEND_URL || "/", - debug: import.meta.env.DEV, - auth: { - type: "session", - }, -}) -``` - -You initialize the SDK passing it the following options: - -- `baseUrl`: The URL to the Medusa server. -- `debug`: Whether to enable logging debug messages. This should only be enabled in development. -- `auth.type`: The authentication method used in the client application, which is `session` in the Medusa Admin dashboard. - -Notice that you use `import.meta.env` to access environment variables in your customizations because the Medusa Admin is built on top of Vite. Learn more in [this chapter](https://docs.medusajs.com/learn/fundamentals/admin/environment-variables/index.html.md). - -You can now use the SDK to send requests to the Medusa server. - -Learn more about the JS SDK and its options in [this reference](https://docs.medusajs.com/resources/js-sdk/index.html.md). - -*** - -## 4. Add a UI Route to Show Brands - -You'll now add the UI route that shows the paginated list of brands. A UI route is a React component created in a `page.tsx` file under a sub-directory of `src/admin/routes`. The file's path relative to src/admin/routes determines its path in the dashboard. - -Learn more about UI routes in [this chapter](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md). - -So, to add the UI route at the `localhost:9000/app/brands` path, create the file `src/admin/routes/brands/page.tsx` with the following content: - -![Directory structure of the Medusa application after adding the UI route.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733472011/Medusa%20Book/brands-admin-dir-overview-3_syytld.jpg) - -```tsx title="src/admin/routes/brands/page.tsx" highlights={uiRouteHighlights} -import { defineRouteConfig } from "@medusajs/admin-sdk" -import { TagSolid } from "@medusajs/icons" -import { - Container, -} from "@medusajs/ui" -import { useQuery } from "@tanstack/react-query" -import { sdk } from "../../lib/sdk" -import { useMemo, useState } from "react" - -const BrandsPage = () => { - // TODO retrieve brands - - return ( - - {/* TODO show brands */} - - ) -} - -export const config = defineRouteConfig({ - label: "Brands", - icon: TagSolid, -}) - -export default BrandsPage -``` - -A route's file must export the React component that will be rendered in the new page. It must be the default export of the file. You can also export configurations that add a link in the sidebar for the UI route. You create these configurations using `defineRouteConfig` from the Admin Extension SDK. - -So far, you only show a container. In admin customizations, use components from the [Medusa UI package](https://docs.medusajs.com/ui/index.html.md) to maintain a consistent user interface and design in the dashboard. - -### Retrieve Brands From API Route - -You'll now update the UI route to retrieve the brands from the API route you added earlier. - -First, add the following type in `src/admin/routes/brands/page.tsx`: - -```tsx title="src/admin/routes/brands/page.tsx" -type Brand = { - id: string - name: string -} -type BrandsResponse = { - brands: Brand[] - count: number - limit: number - offset: number -} -``` - -You define the type for a brand, and the type of expected response from the `GET /admin/brands` API route. - -To display the brands, you'll use Medusa UI's [DataTable](https://docs.medusajs.com/ui/components/data-table/index.html.md) component. So, add the following imports in `src/admin/routes/brands/page.tsx`: - -```tsx title="src/admin/routes/brands/page.tsx" -import { - // ... - Heading, - createDataTableColumnHelper, - DataTable, - DataTablePaginationState, - useDataTable, -} from "@medusajs/ui" -``` - -You import the `DataTable` component and the following utilities: - -- `createDataTableColumnHelper`: A utility to create columns for the data table. -- `DataTablePaginationState`: A type that holds the pagination state of the data table. -- `useDataTable`: A hook to initialize and configure the data table. - -You also import the `Heading` component to show a heading above the data table. - -Next, you'll define the table's columns. Add the following before the `BrandsPage` component: - -```tsx title="src/admin/routes/brands/page.tsx" -const columnHelper = createDataTableColumnHelper() - -const columns = [ - columnHelper.accessor("id", { - header: "ID", - }), - columnHelper.accessor("name", { - header: "Name", - }), -] -``` - -You use the `createDataTableColumnHelper` utility to create columns for the data table. You define two columns for the ID and name of the brands. - -Then, replace the `// TODO retrieve brands` in the component with the following: - -```tsx title="src/admin/routes/brands/page.tsx" highlights={queryHighlights} -const limit = 15 -const [pagination, setPagination] = useState({ - pageSize: limit, - pageIndex: 0, -}) -const offset = useMemo(() => { - return pagination.pageIndex * limit -}, [pagination]) - -const { data, isLoading } = useQuery({ - queryFn: () => sdk.client.fetch(`/admin/brands`, { - query: { - limit, - offset, - }, - }), - queryKey: [["brands", limit, offset]], -}) - -// TODO configure data table -``` - -To enable pagination in the `DataTable` component, you need to define a state variable of type `DataTablePaginationState`. It's an object having the following properties: - -- `pageSize`: The maximum number of items per page. You set it to `15`. -- `pageIndex`: A zero-based index of the current page of items. - -You also define a memoized `offset` value that indicates the number of items to skip before retrieving the current page's items. - -Then, you use `useQuery` from [Tanstack (React) Query](https://tanstack.com/query/latest) to query the Medusa server. Tanstack Query provides features like asynchronous state management and optimized caching. - -Do not install Tanstack Query as that will cause unexpected errors in your development. If you prefer installing it for better auto-completion in your code editor, make sure to install `v5.64.2` as a development dependency. - -In the `queryFn` function that executes the query, you use the JS SDK's `client.fetch` method to send a request to your custom API route. The first parameter is the route's path, and the second is an object of request configuration and data. You pass the query parameters in the `query` property. - -This sends a request to the [Get Brands API route](#1-get-brands-api-route), passing the pagination query parameters. Whenever `currentPage` is updated, the `offset` is also updated, which will send a new request to retrieve the brands for the current page. - -### Display Brands Table - -Finally, you'll display the brands in a data table. Replace the `// TODO configure data table` in the component with the following: - -```tsx title="src/admin/routes/brands/page.tsx" -const table = useDataTable({ - columns, - data: data?.brands || [], - getRowId: (row) => row.id, - rowCount: data?.count || 0, - isLoading, - pagination: { - state: pagination, - onPaginationChange: setPagination, - }, -}) -``` - -You use the `useDataTable` hook to initialize and configure the data table. It accepts an object with the following properties: - -- `columns`: The columns of the data table. You created them using the `createDataTableColumnHelper` utility. -- `data`: The brands to display in the table. -- `getRowId`: A function that returns a unique identifier for a row. -- `rowCount`: The total count of items. This is used to determine the number of pages. -- `isLoading`: A boolean indicating whether the data is loading. -- `pagination`: An object to configure pagination. It accepts the following properties: - - `state`: The pagination state of the data table. - - `onPaginationChange`: A function to update the pagination state. - -Then, replace the `{/* TODO show brands */}` in the return statement with the following: - -```tsx title="src/admin/routes/brands/page.tsx" - - - Brands - - - - -``` - -This renders the data table that shows the brands with pagination. The `DataTable` component accepts the `instance` prop, which is the object returned by the `useDataTable` hook. - -*** - -## Test it Out - -To test out the UI route, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Then, open the admin dashboard at `http://localhost:9000/app`. After you log in, you'll find a new "Brands" sidebar item. Click on it to see the brands in your store. You can also go to `http://localhost:9000/app/brands` to see the page. - -![A new sidebar item is added for the new brands UI route.

Initialize JS SDK - -In your custom widget, you'll retrieve the product's brand by sending a request to the Medusa server. Medusa has a [JS SDK](https://docs.medusajs.com/resources/js-sdk/index.html.md) that simplifies sending requests to the server's API routes. - -So, you'll start by configuring the JS SDK.

The function receives an object as a parameter that has a `zone` property, whose value is the zone to inject the widget to. - -Since the widget is injected at the top of the product details page, the widget receives the product's details as a parameter. - -In the widget, you use [Tanstack (React) Query](https://tanstack.com/query/latest) to query the Medusa server. Tanstack Query provides features like asynchronous state management and optimized caching. In the `queryFn` function that executes the query, you use the JS SDK to send a request to the [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid), passing `+brand.*` in the `fields` query parameter to retrieve the product's brand. - -Do not install Tanstack Query as that will cause unexpected errors in your development. If you prefer installing it for better auto-completion in your code editor, make sure to install `v5.64.2` as a development dependency. - -You then render a section that shows the brand's name.

A workflow is a series of queries and actions, called steps, that complete a task spanning across modules. You construct a workflow similar to a regular function, but it's a special function that allows you to define roll-back logic, retry configurations, and more advanced features. - -The workflow you'll create in this chapter will use the Brand Module's service to implement the feature of creating a brand. In the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll expose an API route that allows admin users to create a brand, and you'll use this workflow in the route's implementation. - -Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). - -### Prerequisites - -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) - -*** - -## 1. Create createBrandStep - -A workflow consists of a series of steps, each step created in a TypeScript or JavaScript file under the `src/workflows` directory. A step is defined using `createStep` from the Workflows SDK - -The workflow you're creating in this guide has one step to create the brand. So, create the file `src/workflows/create-brand.ts` with the following content: - -![Directory structure in the Medusa project after adding the file for createBrandStep](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869184/Medusa%20Book/brand-workflow-dir-overview-1_fjvf5j.jpg) - -```ts title="src/workflows/create-brand.ts" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { BRAND_MODULE } from "../modules/brand" -import BrandModuleService from "../modules/brand/service" - -export type CreateBrandStepInput = { - name: string -} - -export const createBrandStep = createStep( - "create-brand-step", - async (input: CreateBrandStepInput, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - const brand = await brandModuleService.createBrands(input) - - return new StepResponse(brand, brand.id) - } -) -``` - -You create a `createBrandStep` using the `createStep` function. It accepts the step's unique name as a first parameter, and the step's function as a second parameter. - -The step function receives two parameters: input passed to the step when it's invoked, and an object of general context and configurations. This object has a `container` property, which is the Medusa container. - -The [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) is a registry of Framework and commerce tools accessible in your customizations, such as a workflow's step. The Medusa application registers the services of core and custom modules in the container, allowing you to resolve and use them. - -So, In the step function, you use the Medusa container to resolve the Brand Module's service and use its generated `createBrands` method, which accepts an object of brands to create. - -Learn more about the generated `create` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/create/index.html.md). - -A step must return an instance of `StepResponse`. Its first parameter is the data returned by the step, and the second is the data passed to the compensation function, which you'll learn about next. - -### Add Compensation Function to Step - -You define for each step a compensation function that's executed when an error occurs in the workflow. The compensation function defines the logic to roll-back the changes made by the step. This ensures your data remains consistent if an error occurs, which is especially useful when you integrate third-party services. - -Learn more about the compensation function in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). - -To add a compensation function to the `createBrandStep`, pass it as a third parameter to `createStep`: - -```ts title="src/workflows/create-brand.ts" -export const createBrandStep = createStep( - // ... - async (id: string, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - await brandModuleService.deleteBrands(id) - } -) -``` - -The compensation function's first parameter is the brand's ID which you passed as a second parameter to the step function's returned `StepResponse`. It also accepts a context object with a `container` property as a second parameter, similar to the step function. - -In the compensation function, you resolve the Brand Module's service from the Medusa container, then use its generated `deleteBrands` method to delete the brand created by the step. This method accepts the ID of the brand to delete. - -Learn more about the generated `delete` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/delete/index.html.md). - -So, if an error occurs during the workflow's execution, the brand that was created by the step is deleted to maintain data consistency. - -*** - -## 2. Create createBrandWorkflow - -You can now create the workflow that runs the `createBrandStep`. A workflow is created in a TypeScript or JavaScript file under the `src/workflows` directory. In the file, you use `createWorkflow` from the Workflows SDK to create the workflow. - -Add the following content in the same `src/workflows/create-brand.ts` file: - -```ts title="src/workflows/create-brand.ts" -// other imports... -import { - // ... - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" - -// ... - -type CreateBrandWorkflowInput = { - name: string -} - -export const createBrandWorkflow = createWorkflow( - "create-brand", - (input: CreateBrandWorkflowInput) => { - const brand = createBrandStep(input) - - return new WorkflowResponse(brand) - } -) -``` - -You create the `createBrandWorkflow` using the `createWorkflow` function. This function accepts two parameters: the workflow's unique name, and the workflow's constructor function holding the workflow's implementation. - -The constructor function accepts the workflow's input as a parameter. In the function, you invoke the `createBrandStep` you created in the previous step to create a brand. - -A workflow must return an instance of `WorkflowResponse`. It accepts as a parameter the data to return to the workflow's executor. - -*** - -## Next Steps: Expose Create Brand API Route - -You now have a `createBrandWorkflow` that you can execute to create a brand. - -In the next chapter, you'll add an API route that allows admin users to create a brand. You'll learn how to create the API route, and execute in it the workflow you implemented in this chapter. - - -# Guide: Implement Brand Module - -In this chapter, you'll build a Brand Module that adds a `brand` table to the database and provides data-management features for it. - -A module is a reusable package of functionalities related to a single domain or integration. Medusa comes with multiple pre-built modules for core commerce needs, such as the [Cart Module](https://docs.medusajs.com/resources/commerce-modules/cart/index.html.md) that holds the data models and business logic for cart operations. - -In a module, you create data models and business logic to manage them. In the next chapters, you'll see how you use the module to build commerce features. - -Learn more about modules in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). - -## 1. Create Module Directory - -Modules are created in a sub-directory of `src/modules`. So, start by creating the directory `src/modules/brand` that will hold the Brand Module's files. - -![Directory structure in Medusa project after adding the brand directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868844/Medusa%20Book/brand-dir-overview-1_hxwvgx.jpg) - -*** - -## 2. Create Data Model - -A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -Learn more about data models in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#1-create-data-model/index.html.md). - -You create a data model in a TypeScript or JavaScript file under the `models` directory of a module. So, to create a data model that represents a new `brand` table in the database, create the file `src/modules/brand/models/brand.ts` with the following content: - -![Directory structure in module after adding the brand data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868920/Medusa%20Book/brand-dir-overview-2_lexhdl.jpg) - -```ts title="src/modules/brand/models/brand.ts" -import { model } from "@medusajs/framework/utils" - -export const Brand = model.define("brand", { - id: model.id().primaryKey(), - name: model.text(), -}) -``` - -You create a `Brand` data model which has an `id` primary key property, and a `name` text property. - -You define the data model using the `define` method of the DML. It accepts two parameters: - -1. The first one is the name of the data model's table in the database. Use snake-case names. -2. The second is an object, which is the data model's schema. - -Learn about other property types in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties/index.html.md). - -*** - -## 3. Create Module Service - -You perform database operations on your data models in a service, which is a class exported by the module and acts like an interface to its functionalities. - -In this step, you'll create the Brand Module's service that provides methods to manage the `Brand` data model. In the next chapters, you'll use this service when exposing custom features that involve managing brands. - -Learn more about services in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#2-create-service/index.html.md). - -You define a service in a `service.ts` or `service.js` file at the root of your module's directory. So, create the file `src/modules/brand/service.ts` with the following content: - -![Directory structure in module after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868984/Medusa%20Book/brand-dir-overview-3_jo7baj.jpg) - -```ts title="src/modules/brand/service.ts" highlights={serviceHighlights} -import { MedusaService } from "@medusajs/framework/utils" -import { Brand } from "./models/brand" - -class BrandModuleService extends MedusaService({ - Brand, -}) { - -} - -export default BrandModuleService -``` - -The `BrandModuleService` extends a class returned by `MedusaService` from the Modules SDK. This function generates a class with data-management methods for your module's data models. - -The `MedusaService` function receives an object of the module's data models as a parameter, and generates methods to manage those data models. So, the `BrandModuleService` now has methods like `createBrands` and `retrieveBrand` to manage the `Brand` data model. - -You'll use these methods in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). - -Find a reference of all generated methods in [this guide](https://docs.medusajs.com/resources/service-factory-reference/index.html.md). - -*** - -## 4. Export Module Definition - -A module must export a definition that tells Medusa the name of the module and its main service. This definition is exported in an `index.ts` file at the module's root directory. - -So, to export the Brand Module's definition, create the file `src/modules/brand/index.ts` with the following content: - -![Directory structure in module after adding the definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869045/Medusa%20Book/brand-dir-overview-4_nf8ymw.jpg) - -```ts title="src/modules/brand/index.ts" -import { Module } from "@medusajs/framework/utils" -import BrandModuleService from "./service" - -export const BRAND_MODULE = "brand" - -export default Module(BRAND_MODULE, { - service: BrandModuleService, -}) -``` - -You use `Module` from the Modules SDK to create the module's definition. It accepts two parameters: - -1. The module's name (`brand`). You'll use this name when you use this module in other customizations. -2. An object with a required property `service` indicating the module's main service. - -You export `BRAND_MODULE` to reference the module's name more reliably in other customizations. - -*** - -## 5. Add Module to Medusa's Configurations - -To start using your module, you must add it to Medusa's configurations in `medusa-config.ts`. - -The object passed to `defineConfig` in `medusa-config.ts` accepts a `modules` property, whose value is an array of modules to add to the application. So, add the following in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/brand", - }, - ], -}) -``` - -The Brand Module is now added to your Medusa application. You'll start using it in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). - -*** - -## 6. Generate and Run Migrations - -A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations ensure that your module is re-usable and removes friction when working in a team, making it easy to reflect changes across team members' databases. - -Learn more about migrations in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#5-generate-migrations/index.html.md). - -[Medusa's CLI tool](https://docs.medusajs.com/resources/medusa-cli/index.html.md) allows you to generate migration files for your module, then run those migrations to reflect the changes in the database. So, run the following commands in your Medusa application's directory: - -```bash -npx medusa db:generate brand -npx medusa db:migrate -``` - -The `db:generate` command accepts as an argument the name of the module to generate the migrations for, and the `db:migrate` command runs all migrations that haven't been run yet in the Medusa application. - -*** - -## Next Step: Create Brand Workflow - -The Brand Module now creates a `brand` table in the database and provides a class to manage its records. - -In the next chapter, you'll implement the functionality to create a brand in a workflow. You'll then use that workflow in a later chapter to expose an endpoint that allows admin users to create a brand. - - -# Guide: Sync Brands from Medusa to Third-Party - -In the [previous chapter](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md), you created a CMS Module that integrates a dummy third-party system. You can now perform actions using that module within your custom flows. - -In another previous chapter, you [added a workflow](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md) that creates a brand. After integrating the CMS, you want to sync that brand to the third-party system as well. - -Medusa has an event system that emits events when an operation is performed. It allows you to listen to those events and perform an asynchronous action in a function called a [subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). This is useful to perform actions that aren't integral to the original flow, such as syncing data to a third-party system. - -Learn more about Medusa's event system and subscribers in [this chapter](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). - -In this chapter, you'll modify the `createBrandWorkflow` you created before to emit a custom event that indicates a brand was created. Then, you'll listen to that event in a subscriber to sync the brand to the third-party CMS. You'll implement the sync logic within a workflow that you execute in the subscriber. - -### Prerequisites - -- [createBrandWorkflow](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md) -- [CMS Module](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) - -## 1. Emit Event in createBrandWorkflow - -Since syncing the brand to the third-party system isn't integral to creating a brand, you'll emit a custom event indicating that a brand was created. - -Medusa provides an `emitEventStep` that allows you to emit an event in your workflows. So, in the `createBrandWorkflow` defined in `src/workflows/create-brand.ts`, use the `emitEventStep` helper step after the `createBrandStep`: - -```ts title="src/workflows/create-brand.ts" highlights={eventHighlights} -// other imports... -import { - emitEventStep, -} from "@medusajs/medusa/core-flows" - -// ... - -export const createBrandWorkflow = createWorkflow( - "create-brand", - (input: CreateBrandInput) => { - // ... - - emitEventStep({ - eventName: "brand.created", - data: { - id: brand.id, - }, - }) - - return new WorkflowResponse(brand) - } -) -``` - -The `emitEventStep` accepts an object parameter having two properties: - -- `eventName`: The name of the event to emit. You'll use this name later to listen to the event in a subscriber. -- `data`: The data payload to emit with the event. This data is passed to subscribers that listen to the event. You add the brand's ID to the data payload, informing the subscribers which brand was created. - -You'll learn how to handle this event in a later step. - -*** - -## 2. Create Sync to Third-Party System Workflow - -The subscriber that will listen to the `brand.created` event will sync the created brand to the third-party CMS. So, you'll implement the syncing logic in a workflow, then execute the workflow in the subscriber. - -Workflows have a built-in durable execution engine that helps you complete tasks spanning multiple systems. Also, their rollback mechanism ensures that data is consistent across systems even when errors occur during execution. - -Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). - -You'll create a `syncBrandToSystemWorkflow` that has two steps: - -- `useQueryGraphStep`: a step that Medusa provides to retrieve data using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). You'll use this to retrieve the brand's details using its ID. -- `syncBrandToCmsStep`: a step that you'll create to sync the brand to the CMS. - -### syncBrandToCmsStep - -To implement the step that syncs the brand to the CMS, create the file `src/workflows/sync-brands-to-cms.ts` with the following content: - -![Directory structure of the Medusa application after adding the file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493547/Medusa%20Book/cms-dir-overview-4_u5t0ug.jpg) - -```ts title="src/workflows/sync-brands-to-cms.ts" highlights={syncStepHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { InferTypeOf } from "@medusajs/framework/types" -import { Brand } from "../modules/brand/models/brand" -import { CMS_MODULE } from "../modules/cms" -import CmsModuleService from "../modules/cms/service" - -type SyncBrandToCmsStepInput = { - brand: InferTypeOf -} - -const syncBrandToCmsStep = createStep( - "sync-brand-to-cms", - async ({ brand }: SyncBrandToCmsStepInput, { container }) => { - const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) - - await cmsModuleService.createBrand(brand) - - return new StepResponse(null, brand.id) - }, - async (id, { container }) => { - if (!id) { - return - } - - const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) - - await cmsModuleService.deleteBrand(id) - } -) -``` - -You create the `syncBrandToCmsStep` that accepts a brand as an input. In the step, you resolve the CMS Module's service from the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) and use its `createBrand` method. This method will create the brand in the third-party CMS. - -You also pass the brand's ID to the step's compensation function. In this function, you delete the brand in the third-party CMS if an error occurs during the workflow's execution. - -Learn more about compensation functions in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). - -### Create Workflow - -You can now create the workflow that uses the above step. Add the workflow to the same `src/workflows/sync-brands-to-cms.ts` file: - -```ts title="src/workflows/sync-brands-to-cms.ts" highlights={syncWorkflowHighlights} -// other imports... -import { - // ... - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" - -// ... - -type SyncBrandToCmsWorkflowInput = { - id: string -} - -export const syncBrandToCmsWorkflow = createWorkflow( - "sync-brand-to-cms", - (input: SyncBrandToCmsWorkflowInput) => { - // @ts-ignore - const { data: brands } = useQueryGraphStep({ - entity: "brand", - fields: ["*"], - filters: { - id: input.id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - syncBrandToCmsStep({ - brand: brands[0], - } as SyncBrandToCmsStepInput) - - return new WorkflowResponse({}) - } -) -``` - -You create a `syncBrandToCmsWorkflow` that accepts the brand's ID as input. The workflow has the following steps: - -- `useQueryGraphStep`: Retrieve the brand's details using Query. You pass the brand's ID as a filter, and set the `throwIfKeyNotFound` option to true so that the step throws an error if a brand with the specified ID doesn't exist. -- `syncBrandToCmsStep`: Create the brand in the third-party CMS. - -You'll execute this workflow in the subscriber next. - -Learn more about `useQueryGraphStep` in [this reference](https://docs.medusajs.com/resources/references/helper-steps/useQueryGraphStep/index.html.md). - -*** - -## 3. Handle brand.created Event - -You now have a workflow with the logic to sync a brand to the CMS. You need to execute this workflow whenever the `brand.created` event is emitted. So, you'll create a subscriber that listens to and handle the event. - -Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, create the file `src/subscribers/brand-created.ts` with the following content: - -![Directory structure of the Medusa application after adding the subscriber](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493774/Medusa%20Book/cms-dir-overview-5_iqqwvg.jpg) - -```ts title="src/subscribers/brand-created.ts" highlights={subscriberHighlights} -import type { - SubscriberConfig, - SubscriberArgs, -} from "@medusajs/framework" -import { syncBrandToCmsWorkflow } from "../workflows/sync-brands-to-cms" - -export default async function brandCreatedHandler({ - event: { data }, - container, -}: SubscriberArgs<{ id: string }>) { - await syncBrandToCmsWorkflow(container).run({ - input: data, - }) -} - -export const config: SubscriberConfig = { - event: "brand.created", -} -``` - -A subscriber file must export: - -- The asynchronous function that's executed when the event is emitted. This must be the file's default export. -- An object that holds the subscriber's configurations. It has an `event` property that indicates the name of the event that the subscriber is listening to. - -The subscriber function accepts an object parameter that has two properties: - -- `event`: An object of event details. Its `data` property holds the event's data payload, which is the brand's ID. -- `container`: The Medusa container used to resolve Framework and commerce tools. - -In the function, you execute the `syncBrandToCmsWorkflow`, passing it the data payload as an input. So, everytime a brand is created, Medusa will execute this function, which in turn executes the workflow to sync the brand to the CMS. - -Learn more about subscribers in [this chapter](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). - -*** - -## Test it Out - -To test the subscriber and workflow out, you'll use the [Create Brand API route](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md) you created in a previous chapter. - -First, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Since the `/admin/brands` API route has a `/admin` prefix, it's only accessible by authenticated admin users. So, to retrieve an authenticated token of your admin user, send a `POST` request to the `/auth/user/emailpass` API Route: - -```bash -curl -X POST 'http://localhost:9000/auth/user/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "admin@medusa-test.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password with your admin user's credentials. - -Don't have an admin user? Refer to [this guide](https://docs.medusajs.com/learn/installation#create-medusa-admin-user/index.html.md). - -Then, send a `POST` request to `/admin/brands`, passing the token received from the previous request in the `Authorization` header: - -```bash -curl -X POST 'http://localhost:9000/admin/brands' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "name": "Acme" -}' -``` - -This request returns the created brand. If you check the logs, you'll find the `brand.created` event was emitted, and that the request to the third-party system was simulated: - -```plain -info: Processing brand.created which has 1 subscribers -http: POST /admin/brands ← - (200) - 16.418 ms -info: Sending a POST request to /brands. -info: Request Data: { - "id": "01JEDWENYD361P664WRQPMC3J8", - "name": "Acme", - "created_at": "2024-12-06T11:42:32.909Z", - "updated_at": "2024-12-06T11:42:32.909Z", - "deleted_at": null -} -info: API Key: "123" -``` - -*** - -## Next Chapter: Sync Brand from Third-Party CMS to Medusa - -You can also automate syncing data from a third-party system to Medusa at a regular interval. In the next chapter, you'll learn how to sync brands from the third-party CMS to Medusa once a day. - - -# Guide: Integrate Third-Party Brand System - -In the previous chapters, you've created a [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) that adds brands to your application. In this chapter, you'll integrate a dummy Content-Management System (CMS) in a new module. The module's service will provide methods to retrieve and manage brands in the CMS. You'll later use this service to sync data from and to the CMS. - -Learn more about modules in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). - -## 1. Create Module Directory - -You'll integrate the third-party system in a new CMS Module. So, create the directory `src/modules/cms` that will hold the module's resources. - -![Directory structure after adding the directory for the CMS Module](https://res.cloudinary.com/dza7lstvk/image/upload/v1733492447/Medusa%20Book/cms-dir-overview-1_gasguk.jpg) - -*** - -## 2. Create Module Service - -Next, you'll create the module's service. It will provide methods to connect and perform actions with the third-party system. - -Create the CMS Module's service at `src/modules/cms/service.ts` with the following content: - -![Directory structure after adding the CMS Module's service](https://res.cloudinary.com/dza7lstvk/image/upload/v1733492583/Medusa%20Book/cms-dir-overview-2_zwcwh3.jpg) - -```ts title="src/modules/cms/service.ts" highlights={serviceHighlights} -import { Logger, ConfigModule } from "@medusajs/framework/types" - -export type ModuleOptions = { - apiKey: string -} - -type InjectedDependencies = { - logger: Logger - configModule: ConfigModule -} - -class CmsModuleService { - private options_: ModuleOptions - private logger_: Logger - - constructor({ logger }: InjectedDependencies, options: ModuleOptions) { - this.logger_ = logger - this.options_ = options - - // TODO initialize SDK - } -} - -export default CmsModuleService -``` - -You create a `CmsModuleService` that will hold the methods to connect to the third-party CMS. A service's constructor accepts two parameters: - -1. The module's container. Since a module is [isolated](https://docs.medusajs.com/learn/fundamentals/modules/isolation/index.html.md), it has a [local container](https://docs.medusajs.com/learn/fundamentals/modules/container/index.html.md) different than the Medusa container you use in other customizations. This container holds Framework tools like the [Logger utility](https://docs.medusajs.com/learn/debugging-and-testing/logging/index.html.md) and resources within the module. -2. Options passed to the module when it's later added in Medusa's configurations. These options are useful to pass secret keys or configurations that ensure your module is re-usable across applications. For the CMS Module, you accept the API key to connect to the dummy CMS as an option. - -When integrating a third-party system that has a Node.js SDK or client, you can initialize that client in the constructor to be used in the service's methods. - -### Integration Methods - -Next, you'll add methods that simulate sending requests to a third-party CMS. You'll use these methods later to sync brands from and to the CMS. - -Add the following methods in the `CmsModuleService`: - -```ts title="src/modules/cms/service.ts" highlights={methodsHighlights} -export class CmsModuleService { - // ... - - // a dummy method to simulate sending a request, - // in a realistic scenario, you'd use an SDK, fetch, or axios clients - private async sendRequest(url: string, method: string, data?: any) { - this.logger_.info(`Sending a ${method} request to ${url}.`) - this.logger_.info(`Request Data: ${JSON.stringify(data, null, 2)}`) - this.logger_.info(`API Key: ${JSON.stringify(this.options_.apiKey, null, 2)}`) - } - - async createBrand(brand: Record) { - await this.sendRequest("/brands", "POST", brand) - } - - async deleteBrand(id: string) { - await this.sendRequest(`/brands/${id}`, "DELETE") - } - - async retrieveBrands(): Promise[]> { - await this.sendRequest("/brands", "GET") - - return [] - } -} -``` - -The `sendRequest` method sends requests to the third-party CMS. Since this guide isn't using a real CMS, it only simulates the sending by logging messages in the terminal. - -You also add three methods that use the `sendRequest` method: - -- `createBrand` that creates a brand in the third-party system. -- `deleteBrand` that deletes the brand in the third-party system. -- `retrieveBrands` to retrieve a brand from the third-party system. - -*** - -## 3. Export Module Definition - -After creating the module's service, you'll export the module definition indicating the module's name and service. - -Create the file `src/modules/cms/index.ts` with the following content: - -![Directory structure of the Medusa application after adding the module definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733492991/Medusa%20Book/cms-dir-overview-3_b0byks.jpg) - -```ts title="src/modules/cms/index.ts" -import { Module } from "@medusajs/framework/utils" -import CmsModuleService from "./service" - -export const CMS_MODULE = "cms" - -export default Module(CMS_MODULE, { - service: CmsModuleService, -}) -``` - -You use `Module` from the Modules SDK to export the module's defintion, indicating that the module's name is `cms` and its service is `CmsModuleService`. - -*** - -## 4. Add Module to Medusa's Configurations - -Finally, add the module to the Medusa configurations at `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - // ... - { - resolve: "./src/modules/cms", - options: { - apiKey: process.env.CMS_API_KEY, - }, - }, - ], -}) -``` - -The object passed in `modules` accept an `options` property, whose value is an object of options to pass to the module. These are the options you receive in the `CmsModuleService`'s constructor. - -You can add the `CMS_API_KEY` environment variable to `.env`: - -```bash -CMS_API_KEY=123 -``` - -*** - -## Next Steps: Sync Brand From Medusa to CMS - -You can now use the CMS Module's service to perform actions on the third-party CMS. - -In the next chapter, you'll learn how to emit an event when a brand is created, then handle that event to sync the brand from Medusa to the third-party service. - - -# Guide: Define Module Link Between Brand and Product - -In this chapter, you'll learn how to define a module link between a brand defined in the [custom Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md), and a product defined in the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md) that's available in your Medusa application out-of-the-box. - -Modules are [isolated](https://docs.medusajs.com/learn/fundamentals/modules/isolation/index.html.md) from other resources, ensuring that they're integrated into the Medusa application without side effects. However, you may need to associate data models of different modules, or you're trying to extend data models from Commerce Modules with custom properties. To do that, you define module links. - -A module link forms an association between two data models of different modules while maintaining module isolation. You can then manage and query linked records of the data models using Medusa's Modules SDK. - -In this chapter, you'll define a module link between the `Brand` data model of the Brand Module, and the `Product` data model of the Product Module. In later chapters, you'll manage and retrieve linked product and brand records. - -Learn more about module links in [this chapters](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md). - -### Prerequisites - -- [Brand Module having a Brand data model](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) - -## 1. Define Link - -Links are defined in a TypeScript or JavaScript file under the `src/links` directory. The file defines and exports the link using `defineLink` from the Modules SDK. - -So, to define a link between the `Product` and `Brand` models, create the file `src/links/product-brand.ts` with the following content: - -![The directory structure of the Medusa application after adding the link.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733329897/Medusa%20Book/brands-link-dir-overview_t1rhlp.jpg) - -```ts title="src/links/product-brand.ts" highlights={highlights} -import BrandModule from "../modules/brand" -import ProductModule from "@medusajs/medusa/product" -import { defineLink } from "@medusajs/framework/utils" - -export default defineLink( - { - linkable: ProductModule.linkable.product, - isList: true, - }, - BrandModule.linkable.brand -) -``` - -You import each module's definition object from the `index.ts` file of the module's directory. Each module object has a special `linkable` property that holds the data models' link configurations. - -The `defineLink` function accepts two parameters of the same type, which is either: - -- The data model's link configuration, which you access from the Module's `linkable` property; -- Or an object that has two properties: - - `linkable`: the data model's link configuration, which you access from the Module's `linkable` property. - - `isList`: A boolean indicating whether many records of the data model can be linked to the other model. - -So, in the above code snippet, you define a link between the `Product` and `Brand` data models. Since a brand can be associated with multiple products, you enable `isList` in the `Product` model's object. - -*** - -## 2. Sync the Link to the Database - -A module link is represented in the database as a table that stores the IDs of linked records. So, after defining the link, run the following command to create the module link's table in the database: - -```bash -npx medusa db:migrate -``` - -This command reflects migrations on the database and syncs module links, which creates a table for the `product-brand` link. - -You can also run the `npx medusa db:sync-links` to just sync module links without running migrations. - -*** - -## Next Steps: Extend Create Product Flow - -In the next chapter, you'll extend Medusa's workflow and API route that create a product to allow associating a brand with a product. You'll also learn how to link brand and product records. - - -# Guide: Schedule Syncing Brands from Third-Party - -In the previous chapters, you've [integrated a third-party CMS](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) and implemented the logic to [sync created brands](https://docs.medusajs.com/learn/customization/integrate-systems/handle-event/index.html.md) from Medusa to the CMS. - -However, when you integrate a third-party system, you want the data to be in sync between the Medusa application and the system. One way to do so is by automatically syncing the data once a day. - -You can create an action to be automatically executed at a specified interval using scheduled jobs. A scheduled job is an asynchronous function with a specified schedule of when the Medusa application should run it. Scheduled jobs are useful to automate repeated tasks. - -Learn more about scheduled jobs in [this chapter](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md). - -In this chapter, you'll create a scheduled job that triggers syncing the brands from the third-party CMS to Medusa once a day. You'll implement the syncing logic in a workflow, and execute that workflow in the scheduled job. - -### Prerequisites - -- [CMS Module](https://docs.medusajs.com/learn/customization/integrate-systems/service/index.html.md) - -*** - -## 1. Implement Syncing Workflow - -You'll start by implementing the syncing logic in a workflow, then execute the workflow later in the scheduled job. - -Workflows have a built-in durable execution engine that helps you complete tasks spanning multiple systems. Also, their rollback mechanism ensures that data is consistent across systems even when errors occur during execution. - -Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). - -This workflow will have three steps: - -1. `retrieveBrandsFromCmsStep` to retrieve the brands from the CMS. -2. `createBrandsStep` to create the brands retrieved in the first step that don't exist in Medusa. -3. `updateBrandsStep` to update the brands retrieved in the first step that exist in Medusa. - -### retrieveBrandsFromCmsStep - -To create the step that retrieves the brands from the third-party CMS, create the file `src/workflows/sync-brands-from-cms.ts` with the following content: - -![Directory structure of the Medusa application after creating the file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733494196/Medusa%20Book/cms-dir-overview-6_z1omsi.jpg) - -```ts title="src/workflows/sync-brands-from-cms.ts" collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import CmsModuleService from "../modules/cms/service" -import { CMS_MODULE } from "../modules/cms" - -const retrieveBrandsFromCmsStep = createStep( - "retrieve-brands-from-cms", - async (_, { container }) => { - const cmsModuleService: CmsModuleService = container.resolve( - CMS_MODULE - ) - - const brands = await cmsModuleService.retrieveBrands() - - return new StepResponse(brands) - } -) -``` - -You create a `retrieveBrandsFromCmsStep` that resolves the CMS Module's service and uses its `retrieveBrands` method to retrieve the brands in the CMS. You return those brands in the step's response. - -### createBrandsStep - -The brands retrieved in the first step may have brands that don't exist in Medusa. So, you'll create a step that creates those brands. Add the step to the same `src/workflows/sync-brands-from-cms.ts` file: - -```ts title="src/workflows/sync-brands-from-cms.ts" highlights={createBrandsHighlights} collapsibleLines="1-8" expandButtonLabel="Show Imports" -// other imports... -import BrandModuleService from "../modules/brand/service" -import { BRAND_MODULE } from "../modules/brand" - -// ... - -type CreateBrand = { - name: string -} - -type CreateBrandsInput = { - brands: CreateBrand[] -} - -export const createBrandsStep = createStep( - "create-brands-step", - async (input: CreateBrandsInput, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - const brands = await brandModuleService.createBrands(input.brands) - - return new StepResponse(brands, brands) - }, - async (brands, { container }) => { - if (!brands) { - return - } - - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - await brandModuleService.deleteBrands(brands.map((brand) => brand.id)) - } -) -``` - -The `createBrandsStep` accepts the brands to create as an input. It resolves the [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md)'s service and uses the generated `createBrands` method to create the brands. - -The step passes the created brands to the compensation function, which deletes those brands if an error occurs during the workflow's execution. - -Learn more about compensation functions in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). - -### Update Brands Step - -The brands retrieved in the first step may also have brands that exist in Medusa. So, you'll create a step that updates their details to match that of the CMS. Add the step to the same `src/workflows/sync-brands-from-cms.ts` file: - -```ts title="src/workflows/sync-brands-from-cms.ts" highlights={updateBrandsHighlights} -// ... - -type UpdateBrand = { - id: string - name: string -} - -type UpdateBrandsInput = { - brands: UpdateBrand[] -} - -export const updateBrandsStep = createStep( - "update-brands-step", - async ({ brands }: UpdateBrandsInput, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - const prevUpdatedBrands = await brandModuleService.listBrands({ - id: brands.map((brand) => brand.id), - }) - - const updatedBrands = await brandModuleService.updateBrands(brands) - - return new StepResponse(updatedBrands, prevUpdatedBrands) - }, - async (prevUpdatedBrands, { container }) => { - if (!prevUpdatedBrands) { - return - } - - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - await brandModuleService.updateBrands(prevUpdatedBrands) - } -) -``` - -The `updateBrandsStep` receives the brands to update in Medusa. In the step, you retrieve the brand's details in Medusa before the update to pass them to the compensation function. You then update the brands using the Brand Module's `updateBrands` generated method. - -In the compensation function, which receives the brand's old data, you revert the update using the same `updateBrands` method. - -### Create Workflow - -Finally, you'll create the workflow that uses the above steps to sync the brands from the CMS to Medusa. Add to the same `src/workflows/sync-brands-from-cms.ts` file the following: - -```ts title="src/workflows/sync-brands-from-cms.ts" -// other imports... -import { - // ... - createWorkflow, - transform, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" - -// ... - -export const syncBrandsFromCmsWorkflow = createWorkflow( - "sync-brands-from-system", - () => { - const brands = retrieveBrandsFromCmsStep() - - // TODO create and update brands - } -) -``` - -In the workflow, you only use the `retrieveBrandsFromCmsStep` for now, which retrieves the brands from the third-party CMS. - -Next, you need to identify which brands must be created or updated. Since workflows are constructed internally and are only evaluated during execution, you can't access values to perform data manipulation directly. Instead, use [transform](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation/index.html.md) from the Workflows SDK that gives you access to the real-time values of the data, allowing you to create new variables using those values. - -Learn more about data manipulation using `transform` in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation/index.html.md). - -So, replace the `TODO` with the following: - -```ts title="src/workflows/sync-brands-from-cms.ts" -const { toCreate, toUpdate } = transform( - { - brands, - }, - (data) => { - const toCreate: CreateBrand[] = [] - const toUpdate: UpdateBrand[] = [] - - data.brands.forEach((brand) => { - if (brand.external_id) { - toUpdate.push({ - id: brand.external_id as string, - name: brand.name as string, - }) - } else { - toCreate.push({ - name: brand.name as string, - }) - } - }) - - return { toCreate, toUpdate } - } -) - -// TODO create and update the brands -``` - -`transform` accepts two parameters: - -1. The data to be passed to the function in the second parameter. -2. A function to execute only when the workflow is executed. Its return value can be consumed by the rest of the workflow. - -In `transform`'s function, you loop over the brands array to check which should be created or updated. This logic assumes that a brand in the CMS has an `external_id` property whose value is the brand's ID in Medusa. - -You now have the list of brands to create and update. So, replace the new `TODO` with the following: - -```ts title="src/workflows/sync-brands-from-cms.ts" -const created = createBrandsStep({ brands: toCreate }) -const updated = updateBrandsStep({ brands: toUpdate }) - -return new WorkflowResponse({ - created, - updated, -}) -``` - -You first run the `createBrandsStep` to create the brands that don't exist in Medusa, then the `updateBrandsStep` to update the brands that exist in Medusa. You pass the arrays returned by `transform` as the inputs for the steps. - -Finally, you return an object of the created and updated brands. You'll execute this workflow in the scheduled job next. - -*** - -## 2. Schedule Syncing Task - -You now have the workflow to sync the brands from the CMS to Medusa. Next, you'll create a scheduled job that runs this workflow once a day to ensure the data between Medusa and the CMS are always in sync. - -A scheduled job is created in a TypeScript or JavaScript file under the `src/jobs` directory. So, create the file `src/jobs/sync-brands-from-cms.ts` with the following content: - -![Directory structure of the Medusa application after adding the scheduled job](https://res.cloudinary.com/dza7lstvk/image/upload/v1733494592/Medusa%20Book/cms-dir-overview-7_dkjb9s.jpg) - -```ts title="src/jobs/sync-brands-from-cms.ts" -import { MedusaContainer } from "@medusajs/framework/types" -import { syncBrandsFromCmsWorkflow } from "../workflows/sync-brands-from-cms" - -export default async function (container: MedusaContainer) { - const logger = container.resolve("logger") - - const { result } = await syncBrandsFromCmsWorkflow(container).run() - - logger.info( - `Synced brands from third-party system: ${ - result.created.length - } brands created and ${result.updated.length} brands updated.`) -} - -export const config = { - name: "sync-brands-from-system", - schedule: "0 0 * * *", // change to * * * * * for debugging -} -``` - -A scheduled job file must export: - -- An asynchronous function that will be executed at the specified schedule. This function must be the file's default export. -- An object of scheduled jobs configuration. It has two properties: - - `name`: A unique name for the scheduled job. - - `schedule`: A string that holds a [cron expression](https://crontab.guru/) indicating the schedule to run the job. - -The scheduled job function accepts as a parameter the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) used to resolve Framework and commerce tools. You then execute the `syncBrandsFromCmsWorkflow` and use its result to log how many brands were created or updated. - -Based on the cron expression specified in `config.schedule`, Medusa will run the scheduled job every day at midnight. You can also change it to `* * * * *` to run it every minute for easier debugging. - -*** - -## Test it Out - -To test out the scheduled job, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -If you set the schedule to `* * * * *` for debugging, the scheduled job will run in a minute. You'll see in the logs how many brands were created or updated. - -*** - -## Summary - -By following the previous chapters, you utilized the Medusa Framework and orchestration tools to perform and automate tasks that span across systems. - -With Medusa, you can integrate any service from your commerce ecosystem with ease. You don't have to set up separate applications to manage your different customizations, or worry about data inconsistency across systems. Your efforts only go into implementing the business logic that ties your systems together. - - -# Guide: Extend Create Product Flow - -After linking the [custom Brand data model](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) and Medusa's [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md) in the [previous chapter](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md), you'll extend the create product workflow and API route to allow associating a brand with a product. - -Some API routes, including the [Create Product API route](https://docs.medusajs.com/api/admin#products_postproducts), accept an `additional_data` request body parameter. This parameter can hold custom data that's passed to the [hooks](https://docs.medusajs.com/learn/fundamentals/workflows/workflow-hooks/index.html.md) of the workflow executed in the API route, allowing you to consume those hooks and perform actions with the custom data. - -So, in this chapter, to extend the create product flow and associate a brand with a product, you will: - -- Consume the [productsCreated](https://docs.medusajs.com/resources/references/medusa-workflows/createProductsWorkflow#productsCreated/index.html.md) hook of the [createProductsWorkflow](https://docs.medusajs.com/resources/references/medusa-workflows/createProductsWorkflow/index.html.md), which is executed within the workflow after the product is created. You'll link the product with the brand passed in the `additional_data` parameter. -- Extend the Create Product API route to allow passing a brand ID in `additional_data`. - -To learn more about the `additional_data` property and the API routes that accept additional data, refer to [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/additional-data/index.html.md). - -### Prerequisites - -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) -- [Defined link between the Brand and Product data models.](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md) - -*** - -## 1. Consume the productsCreated Hook - -A workflow hook is a point in a workflow where you can inject a step to perform a custom functionality. Consuming a workflow hook allows you to extend the features of a workflow and, consequently, the API route that uses it. - -Learn more about the workflow hooks in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/workflow-hooks/index.html.md). - -The [createProductsWorkflow](https://docs.medusajs.com/resources/references/medusa-workflows/createProductsWorkflow/index.html.md) used in the [Create Product API route](https://docs.medusajs.com/api/admin#products_postproducts) has a `productsCreated` hook that runs after the product is created. You'll consume this hook to link the created product with the brand specified in the request parameters. - -To consume the `productsCreated` hook, create the file `src/workflows/hooks/created-product.ts` with the following content: - -![Directory structure after creating the hook's file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1733384338/Medusa%20Book/brands-hook-dir-overview_ltwr5h.jpg) - -```ts title="src/workflows/hooks/created-product.ts" highlights={hook1Highlights} -import { createProductsWorkflow } from "@medusajs/medusa/core-flows" -import { StepResponse } from "@medusajs/framework/workflows-sdk" -import { Modules } from "@medusajs/framework/utils" -import { LinkDefinition } from "@medusajs/framework/types" -import { BRAND_MODULE } from "../../modules/brand" -import BrandModuleService from "../../modules/brand/service" - -createProductsWorkflow.hooks.productsCreated( - (async ({ products, additional_data }, { container }) => { - if (!additional_data?.brand_id) { - return new StepResponse([], []) - } - - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - // if the brand doesn't exist, an error is thrown. - await brandModuleService.retrieveBrand(additional_data.brand_id as string) - - // TODO link brand to product - }) -) -``` - -Workflows have a special `hooks` property to access its hooks and consume them. Each hook, such as `productsCreated`, accepts a step function as a parameter. The step function accepts the following parameters: - -1. An object having an `additional_data` property, which is the custom data passed in the request body under `additional_data`. The object will also have properties passed from the workflow to the hook, which in this case is the `products` property that holds an array of the created products. -2. An object of properties related to the step's context. It has a `container` property whose value is the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) to resolve Framework and commerce tools. - -In the step, if a brand ID is passed in `additional_data`, you resolve the Brand Module's service and use its generated `retrieveBrand` method to retrieve the brand by its ID. The `retrieveBrand` method will throw an error if the brand doesn't exist. - -### Link Brand to Product - -Next, you want to create a link between the created products and the brand. To do so, you use Link, which is a class from the Modules SDK that provides methods to manage linked records. - -Learn more about Link in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/link/index.html.md). - -To use Link in the `productsCreated` hook, replace the `TODO` with the following: - -```ts title="src/workflows/hooks/created-product.ts" highlights={hook2Highlights} -const link = container.resolve("link") -const logger = container.resolve("logger") - -const links: LinkDefinition[] = [] - -for (const product of products) { - links.push({ - [Modules.PRODUCT]: { - product_id: product.id, - }, - [BRAND_MODULE]: { - brand_id: additional_data.brand_id, - }, - }) -} - -await link.create(links) - -logger.info("Linked brand to products") - -return new StepResponse(links, links) -``` - -You resolve Link from the container. Then you loop over the created products to assemble an array of links to be created. After that, you pass the array of links to Link's `create` method, which will link the product and brand records. - -Each property in the link object is the name of a module, and its value is an object having a `{model_name}_id` property, where `{model_name}` is the snake-case name of the module's data model. Its value is the ID of the record to be linked. The link object's properties must be set in the same order as the link configurations passed to `defineLink`. - -![Diagram showcasing how the order of defining a link affects creating the link](https://res.cloudinary.com/dza7lstvk/image/upload/v1733386156/Medusa%20Book/remote-link-brand-product-exp_fhjmg4.jpg) - -Finally, you return an instance of `StepResponse` returning the created links. - -### Dismiss Links in Compensation - -You can pass as a second parameter of the hook a compensation function that undoes what the step did. It receives as a first parameter the returned `StepResponse`'s second parameter, and the step context object as a second parameter. - -To undo creating the links in the hook, pass the following compensation function as a second parameter to `productsCreated`: - -```ts title="src/workflows/hooks/created-product.ts" -createProductsWorkflow.hooks.productsCreated( - // ... - (async (links, { container }) => { - if (!links?.length) { - return - } - - const link = container.resolve("link") - - await link.dismiss(links) - }) -) -``` - -In the compensation function, if the `links` parameter isn't empty, you resolve Link from the container and use its `dismiss` method. This method removes a link between two records. It accepts the same parameter as the `create` method. - -*** - -## 2. Configure Additional Data Validation - -Now that you've consumed the `productsCreated` hook, you want to configure the `/admin/products` API route that creates a new product to accept a brand ID in its `additional_data` parameter. - -You configure the properties accepted in `additional_data` in the `src/api/middlewares.ts` that exports middleware configurations. So, create the file (or, if already existing, add to the file) `src/api/middlewares.ts` the following content: - -![Directory structure after adding the middelwares file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733386868/Medusa%20Book/brands-middleware-dir-overview_uczos1.jpg) - -```ts title="src/api/middlewares.ts" -import { defineMiddlewares } from "@medusajs/framework/http" -import { z } from "zod" - -// ... - -export default defineMiddlewares({ - routes: [ - // ... - { - matcher: "/admin/products", - method: ["POST"], - additionalDataValidator: { - brand_id: z.string().optional(), - }, - }, - ], -}) -``` - -Objects in `routes` accept an `additionalDataValidator` property that configures the validation rules for custom properties passed in the `additional_data` request parameter. It accepts an object whose keys are custom property names, and their values are validation rules created using [Zod](https://zod.dev/). - -So, `POST` requests sent to `/admin/products` can now pass the ID of a brand in the `brand_id` property of `additional_data`. - -*** - -## Test it Out - -To test it out, first, retrieve the authentication token of your admin user by sending a `POST` request to `/auth/user/emailpass`: - -```bash -curl -X POST 'http://localhost:9000/auth/user/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "admin@medusa-test.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password in the request body with your user's credentials. - -Then, send a `POST` request to `/admin/products` to create a product, and pass in the `additional_data` parameter a brand's ID: - -```bash -curl -X POST 'http://localhost:9000/admin/products' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "title": "Product 1", - "options": [ - { - "title": "Default option", - "values": ["Default option value"] - } - ], - "shipping_profile_id": "{shipping_profile_id}", - "additional_data": { - "brand_id": "{brand_id}" - } -}' -``` - -Make sure to replace `{token}` with the token you received from the previous request, `shipping_profile_id` with the ID of a shipping profile in your application, and `{brand_id}` with the ID of a brand in your application. You can retrieve the ID of a shipping profile either from the Medusa Admin, or the [List Shipping Profiles API route](https://docs.medusajs.com/api/admin#shipping-profiles_getshippingprofiles). - -The request creates a product and returns it. - -In the Medusa application's logs, you'll find the message `Linked brand to products`, indicating that the workflow hook handler ran and linked the brand to the products. - -*** - -## Next Steps: Query Linked Brands and Products - -Now that you've extending the create-product flow to link a brand to it, you want to retrieve the brand details of a product. You'll learn how to do so in the next chapter. - - -# Guide: Query Product's Brands - -In the previous chapters, you [defined a link](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md) between the [custom Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) and Medusa's [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md), then [extended the create-product flow](https://docs.medusajs.com/learn/customization/extend-features/extend-create-product/index.html.md) to link a product to a brand. - -In this chapter, you'll learn how to retrieve a product's brand (and vice-versa) in two ways: Using Medusa's existing API route, or in customizations, such as a custom API route. - -### Prerequisites - -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) -- [Defined link between the Brand and Product data models.](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md) - -*** - -## Approach 1: Retrieve Brands in Existing API Routes - -Medusa's existing API routes accept a `fields` query parameter that allows you to specify the fields and relations of a model to retrieve. So, when you send a request to the [List Products](https://docs.medusajs.com/api/admin#products_getproducts), [Get Product](https://docs.medusajs.com/api/admin#products_getproductsid), or any product-related store or admin routes that accept a `fields` query parameter, you can specify in this parameter to return the product's brands. - -Learn more about using the `fields` query parameter to retrieve custom linked data models in the [Retrieve Custom Linked Data Models from Medusa's API Routes](https://docs.medusajs.com/learn/fundamentals/api-routes/retrieve-custom-links/index.html.md) chapter. - -For example, send the following request to retrieve the list of products with their brands: - -```bash -curl 'http://localhost:9000/admin/products?fields=+brand.*' \ ---header 'Authorization: Bearer {token}' -``` - -Make sure to replace `{token}` with your admin user's authentication token. Learn how to retrieve it in the [API reference](https://docs.medusajs.com/api/store#authentication). - -Any product that is linked to a brand will have a `brand` property in its object: - -```json title="Example Product Object" -{ - "id": "prod_123", - // ... - "brand": { - "id": "01JEB44M61BRM3ARM2RRMK7GJF", - "name": "Acme", - "created_at": "2024-12-05T09:59:08.737Z", - "updated_at": "2024-12-05T09:59:08.737Z", - "deleted_at": null - } -} -``` - -By using the `fields` query parameter, you don't have to re-create existing API routes to get custom data models that you linked to core data models. - -### Limitations: Filtering by Brands in Existing API Routes - -While you can retrieve linked records using the `fields` query parameter of an existing API route, you can't filter by linked records. - -Instead, you'll have to create a custom API route that uses Query to retrieve linked records with filters, as explained in the [Query documentation](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-filters-and-pagination-on-linked-records/index.html.md). - -*** - -## Approach 2: Use Query to Retrieve Linked Records - -You can also retrieve linked records using Query. Query allows you to retrieve data across modules with filters, pagination, and more. You can resolve Query from the Medusa container and use it in your API route or workflow. - -Learn more about Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). - -For example, you can create an API route that retrieves brands and their products. If you followed the [Create Brands API route chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll have the file `src/api/admin/brands/route.ts` with a `POST` API route. Add a new `GET` function to the same file: - -```ts title="src/api/admin/brands/route.ts" highlights={highlights} -// other imports... -import { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const query = req.scope.resolve("query") - - const { data: brands } = await query.graph({ - entity: "brand", - fields: ["*", "products.*"], - }) - - res.json({ brands }) -} -``` - -This adds a `GET` API route at `/admin/brands`. In the API route, you resolve Query from the Medusa container. Query has a `graph` method that runs a query to retrieve data. It accepts an object having the following properties: - -- `entity`: The data model's name as specified in the first parameter of `model.define`. -- `fields`: An array of properties and relations to retrieve. You can pass: - - A property's name, such as `id`, or `*` for all properties. - - A relation or linked model's name, such as `products` (use the plural name since brands are linked to list of products). You suffix the name with `.*` to retrieve all its properties. - -`graph` returns an object having a `data` property, which is the retrieved brands. You return the brands in the response. - -### Test it Out - -To test the API route out, send a `GET` request to `/admin/brands`: - -```bash -curl 'http://localhost:9000/admin/brands' \ --H 'Authorization: Bearer {token}' -``` - -Make sure to replace `{token}` with your admin user's authentication token. Learn how to retrieve it in the [API reference](https://docs.medusajs.com/api/store#authentication). - -This returns the brands in your store with their linked products. For example: - -```json title="Example Response" -{ - "brands": [ - { - "id": "123", - // ... - "products": [ - { - "id": "prod_123", - // ... - } - ] - } - ] -} -``` - -### Limitations: Filtering by Brand in Query - -While you can use Query to retrieve linked records, you can't filter by linked records. - -For an alternative approach, refer to the [Query documentation](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-filters-and-pagination-on-linked-records/index.html.md). - -*** - -## Summary - -By following the examples of the previous chapters, you: - -- Defined a link between the Brand and Product modules's data models, allowing you to associate a product with a brand. -- Extended the create-product workflow and route to allow setting the product's brand while creating the product. -- Queried a product's brand, and vice versa. - -*** - -## Next Steps: Customize Medusa Admin - -Clients, such as the Medusa Admin dashboard, can now use brand-related features, such as creating a brand or setting the brand of a product. - -In the next chapters, you'll learn how to customize the Medusa Admin to show a product's brand on its details page, and to show a new page with the list of brands in your store. - - -# Translate Medusa Admin - -The Medusa Admin supports multiple languages, with the default being English.

These inventory items can be used to represent different parts of a product, or to represent a bundle of products. - -The Medusa application links inventory items from the [Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/index.html.md) to product variants in the [Product Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/index.html.md). Each variant can have multiple inventory items, and these inventory items can be re-used or shared across variants. - -Using inventory kits, you can implement use cases like: - -- [Multi-part products](#multi-part-products): A product that consists of multiple parts, each with its own inventory item. -- [Bundled products](#bundled-products): A product that is sold as a bundle, where each variant in the bundle product can re-use the inventory items of another product that should be sold as part of the bundle. - -*** - -## Multi-Part Products - -Consider your store sells bicycles that consist of a frame, wheels, and seats, and you want to manage the inventory of these parts separately. - -To implement this in Medusa, you can: - -- Create inventory items for each of the different parts. -- For each bicycle product, add a variant whose inventory kit consists of the inventory items of each of the parts. - -Then, whenever a customer purchases a bicycle, the inventory of each part is updated accordingly. You can also use the `required_quantity` of the variant's inventory items to set how much quantity is consumed of the part's inventory when a bicycle is sold. For example, the bicycle's wheels require 2 wheels inventory items to be sold when a bicycle is sold. - -![Diagram showcasing how a variant is linked to multi-part inventory items](https://res.cloudinary.com/dza7lstvk/image/upload/v1736414257/Medusa%20Resources/multi-part-product_kepbnx.jpg) - -### Create Multi-Part Product - -Using the [Medusa Admin](https://docs.medusajs.com/user-guide/products/create/multi-part/index.html.md), you can create a multi-part product by creating its inventory items first, then assigning these inventory items to the product's variant(s). - -Using [workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md), you can implement this by first creating the inventory items: - -```ts highlights={multiPartsHighlights1} -import { - createInventoryItemsWorkflow, - useQueryGraphStep, -} from "@medusajs/medusa/core-flows" -import { createWorkflow } from "@medusajs/framework/workflows-sdk" - -export const createMultiPartProductsWorkflow = createWorkflow( - "create-multi-part-products", - () => { - // Alternatively, you can create a stock location - const { data: stockLocations } = useQueryGraphStep({ - entity: "stock_location", - fields: ["*"], - filters: { - name: "European Warehouse", - }, - }) - - const inventoryItems = createInventoryItemsWorkflow.runAsStep({ - input: { - items: [ - { - sku: "FRAME", - title: "Frame", - location_levels: [ - { - stocked_quantity: 100, - location_id: stockLocations[0].id, - }, - ], - }, - { - sku: "WHEEL", - title: "Wheel", - location_levels: [ - { - stocked_quantity: 100, - location_id: stockLocations[0].id, - }, - ], - }, - { - sku: "SEAT", - title: "Seat", - location_levels: [ - { - stocked_quantity: 100, - location_id: stockLocations[0].id, - }, - ], - }, - ], - }, - }) - - // TODO create the product - } -) -``` - -You start by retrieving the stock location to create the inventory items in.

A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. - -In the module, you define the data models necessary for a feature and the logic to manage these data models. Later, you can build commerce flows around your module. - -In this step, you'll build a Loyalty Module that defines the necessary data models to store and manage loyalty points for customers. - -Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. - -### Create Module Directory - -Modules are created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/loyalty`. - -### Create Data Models - -A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -Refer to the [Data Models documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#1-create-data-model/index.html.md) to learn more. - -For the Loyalty Module, you need to define a `LoyaltyPoint` data model that represents a customer's loyalty points. So, create the file `src/modules/loyalty/models/loyalty-point.ts` with the following content: - -```ts title="src/modules/loyalty/models/loyalty-point.ts" highlights={dmlHighlights} -import { model } from "@medusajs/framework/utils" - -const LoyaltyPoint = model.define("loyalty_point", { - id: model.id().primaryKey(), - points: model.number().default(0), - customer_id: model.text().unique("IDX_LOYALTY_CUSTOMER_ID"), -}) - -export default LoyaltyPoint -``` - -You define the `LoyaltyPoint` data model using the `model.define` method of the DML. It accepts the data model's table name as a first parameter, and the model's schema object as a second parameter. - -The `LoyaltyPoint` data model has the following properties: - -- `id`: A unique ID for the loyalty points. -- `points`: The number of loyalty points a customer has. -- `customer_id`: The ID of the customer who owns the loyalty points. This property has a unique index to ensure that each customer has only one record in the `loyalty_point` table. - -Learn more about defining data model properties in the [Property Types documentation](https://docs.medusajs.com/docs/learn/fundamentals/data-models/properties/index.html.md). - -### Create Module's Service - -You now have the necessary data model in the Loyalty Module, but you'll need to manage its records. You do this by creating a service in the module. - -A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, allowing you to manage your data models, or connect to a third-party service, which is useful if you're integrating with external services. - -Refer to the [Module Service documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#2-create-service/index.html.md) to learn more. - -To create the Loyalty Module's service, create the file `src/modules/loyalty/service.ts` with the following content: - -```ts title="src/modules/loyalty/service.ts" -import { MedusaError, MedusaService } from "@medusajs/framework/utils" -import LoyaltyPoint from "./models/loyalty-point" -import { InferTypeOf } from "@medusajs/framework/types" - -type LoyaltyPoint = InferTypeOf - -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // TODO add methods -} - -export default LoyaltyModuleService -``` - -The `LoyaltyModuleService` extends `MedusaService` from the Modules SDK which generates a class with data-management methods for your module's data models. This saves you time on implementing Create, Read, Update, and Delete (CRUD) methods. - -So, the `LoyaltyModuleService` class now has methods like `createLoyaltyPoints` and `retrieveLoyaltyPoint`. - -Find all methods generated by the `MedusaService` in [the Service Factory reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/service-factory-reference/index.html.md). - -#### Add Methods to the Service - -Aside from the basic CRUD methods, you need to add methods that handle custom functionalities related to loyalty points. - -First, you need a method that adds loyalty points for a customer. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - async addPoints(customerId: string, points: number): Promise { - const existingPoints = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - if (existingPoints.length > 0) { - return await this.updateLoyaltyPoints({ - id: existingPoints[0].id, - points: existingPoints[0].points + points, - }) - } - - return await this.createLoyaltyPoints({ - customer_id: customerId, - points, - }) - } -} -``` - -You add an `addPoints` method that accepts two parameters: the ID of the customer and the points to add. - -In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method, which is automatically generated by the `MedusaService`. If the customer has existing points, you update them with the new points using the `updateLoyaltyPoints` method. - -Otherwise, if the customer doesn't have existing loyalty points, you create a new record with the `createLoyaltyPoints` method. - -The next method you'll add deducts points from the customer's loyalty points, which is useful when the customer redeems points. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async deductPoints(customerId: string, points: number): Promise { - const existingPoints = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - if (existingPoints.length === 0 || existingPoints[0].points < points) { - throw new MedusaError( - MedusaError.Types.NOT_ALLOWED, - "Insufficient loyalty points" - ) - } - - return await this.updateLoyaltyPoints({ - id: existingPoints[0].id, - points: existingPoints[0].points - points, - }) - } -} -``` - -The `deductPoints` method accepts the customer ID and the points to deduct. - -In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method. If the customer doesn't have existing points or if the points to deduct are greater than the existing points, you throw an error. - -Otherwise, you update the customer's loyalty points with the new value using the `updateLoyaltyPoints` method, which is automatically generated by `MedusaService`. - -Next, you'll add the method that retrieves the points of a customer. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async getPoints(customerId: string): Promise { - const points = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - return points[0]?.points || 0 - } -} -``` - -The `getPoints` method accepts the customer ID and retrieves the customer's loyalty points using the `listLoyaltyPoints` method. If the customer has no points, it returns `0`. - -#### Add Method to Map Points to Discount - -Finally, you'll add a method that implements the logic of mapping loyalty points to a discount amount. This is useful when the customer wants to redeem their points during checkout. - -The mapping logic may differ for each use case. For example, you may need to use a third-party service to map the loyalty points discount amount, or use some custom calculation. - -To simplify the logic in this tutorial, you'll use a simple calculation that maps 1 point to 1 currency unit. For example, `100` points = `$100` discount. - -Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async calculatePointsFromAmount(amount: number): Promise { - // Convert amount to points using a standard conversion rate - // For example, $1 = 1 point - // Round down to nearest whole point - const points = Math.floor(amount) - - if (points < 0) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Amount cannot be negative" - ) - } - - return points - } -} -``` - -The `calculatePointsFromAmount` method accepts the amount and converts it to the nearest whole number of points. If the amount is negative, it throws an error. - -You'll use this method later to calculate the amount discounted when a customer redeems their loyalty points. - -### Export Module Definition - -The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. - -So, create the file `src/modules/loyalty/index.ts` with the following content: - -```ts title="src/modules/loyalty/index.ts" -import { Module } from "@medusajs/framework/utils" -import LoyaltyModuleService from "./service" - -export const LOYALTY_MODULE = "loyalty" - -export default Module(LOYALTY_MODULE, { - service: LoyaltyModuleService, -}) -``` - -You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: - -1. The module's name, which is `loyalty`. -2. An object with a required property `service` indicating the module's service. - -You also export the module's name as `LOYALTY_MODULE` so you can reference it later. - -### Add Module to Medusa's Configurations - -Once you finish building the module, add it to Medusa's configurations to start using it. - -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/loyalty", - }, - ], -}) -``` - -Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. - -### Generate Migrations - -Since data models represent tables in the database, you define how they're created in the database with migrations. A migration is a TypeScript or JavaScript file that defines database changes made by a module. - -Refer to the [Migrations documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#5-generate-migrations/index.html.md) to learn more. - -Medusa's CLI tool can generate the migrations for you. To generate a migration for the Loyalty Module, run the following command in your Medusa application's directory: - -```bash -npx medusa db:generate loyalty -``` - -The `db:generate` command of the Medusa CLI accepts the name of the module to generate the migration for. You'll now have a `migrations` directory under `src/modules/loyalty` that holds the generated migration. - -Then, to reflect these migrations on the database, run the following command: - -```bash -npx medusa db:migrate -``` - -The table for the `LoyaltyPoint` data model is now created in the database. - -*** - -## Step 3: Change Loyalty Points Flow - -Now that you have a module that stores and manages loyalty points in the database, you'll start building flows around it that allow customers to earn and redeem points. - -The first flow you'll build will either add points to a customer's loyalty points or deduct them based on a purchased order. If the customer hasn't redeemed points, the points are added to their loyalty points. Otherwise, the points are deducted from their loyalty points. - -To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. - -In this section, you'll build the workflow that adds or deducts loyalty points for an order's customer. Later, you'll execute this workflow when an order is placed. - -Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the order's details. -- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. - -Medusa provides the `useQueryGraphStep` and `updatePromotionsStep` in its `@medusajs/medusa/core-flows` package. So, you'll only implement the other steps. - -### validateCustomerExistsStep - -In the workflow, you first need to validate that the customer is registered. Only registered customers can earn and redeem loyalty points. - -To do this, create the file `src/workflows/steps/validate-customer-exists.ts` with the following content: - -```ts title="src/workflows/steps/validate-customer-exists.ts" -import { CustomerDTO } from "@medusajs/framework/types" -import { createStep } from "@medusajs/framework/workflows-sdk" -import { MedusaError } from "@medusajs/framework/utils" - -export type ValidateCustomerExistsStepInput = { - customer: CustomerDTO | null | undefined -} - -export const validateCustomerExistsStep = createStep( - "validate-customer-exists", - async ({ customer }: ValidateCustomerExistsStepInput) => { - if (!customer) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer not found" - ) - } - - if (!customer.has_account) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer must have an account to earn or manage points" - ) - } - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `validate-customer-exists`. -2. An async function that receives two parameters: - - The step's input, which is in this case an object with the customer's details. - - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, you validate that the customer is defined and that it's registered based on its `has_account` property. Otherwise, you throw an error. - -### getCartLoyaltyPromoStep - -Next, you'll need to retrieve the loyalty promotion applied on the cart, if there's any. This is useful to determine whether the customer has redeemed points. - -Before you create a step, you'll create a utility function that the step uses to retrieve the loyalty promotion of a cart. You'll create it as a separate utility function to use it later in other customizations. - -Create the file `src/utils/promo.ts` with the following content: - -```ts title="src/utils/promo.ts" -import { PromotionDTO, CustomerDTO, CartDTO } from "@medusajs/framework/types" - -export type CartData = CartDTO & { - promotions?: PromotionDTO[] - customer?: CustomerDTO - metadata: { - loyalty_promo_id?: string - } -} - -export function getCartLoyaltyPromotion( - cart: CartData -): PromotionDTO | undefined { - if (!cart?.metadata?.loyalty_promo_id) { - return - } - - return cart.promotions?.find( - (promotion) => promotion.id === cart.metadata.loyalty_promo_id - ) -} -``` - -You create a `getCartLoyaltyPromotion` function that accepts the cart's details as an input and returns the loyalty promotion if it exists. You retrieve the loyalty promotion if its ID is stored in the cart's `metadata.loyalty_promo_id` property. - -You can now create the step that uses this utility to retrieve a carts loyalty points promotion. To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo.ts` with the following content: - -```ts title="src/workflows/steps/get-cart-loyalty-promo.ts" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" -import { MedusaError } from "@medusajs/framework/utils" - -type GetCartLoyaltyPromoStepInput = { - cart: CartData, - throwErrorOn?: "found" | "not-found" -} - -export const getCartLoyaltyPromoStep = createStep( - "get-cart-loyalty-promo", - async ({ cart, throwErrorOn }: GetCartLoyaltyPromoStepInput) => { - const loyaltyPromo = getCartLoyaltyPromotion(cart) - - if (throwErrorOn === "found" && loyaltyPromo) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Loyalty promotion already applied to cart" - ) - } else if (throwErrorOn === "not-found" && !loyaltyPromo) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "No loyalty promotion found on cart" - ) - } - - return new StepResponse(loyaltyPromo) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `cart`: The cart's details. -- `throwErrorOn`: An optional property that indicates whether to throw an error if the loyalty promotion is found or not found. - -The `throwErrorOn` property is useful to make the step reusable in different scenarios, allowing you to use it in later workflows. - -In the step, you call the `getCartLoyaltyPromotion` utility to retrieve the loyalty promotion. If the `throwErrorOn` property is set to `found` and the loyalty promotion is found, you throw an error. - -Otherwise, if the `throwErrorOn` property is set to `not-found` and the loyalty promotion is not found, you throw an error. - -To return data from a step, you return an instance of `StepResponse` from the Workflows SDK. It accepts as a parameter the data to return, which is the loyalty promotion in this case. - -### deductPurchasePointsStep - -If the order's cart has a loyalty promotion, you need to deduct points from the customer's loyalty points. To do this, create the file `src/workflows/steps/deduct-purchase-points.ts` with the following content: - -```ts title="src/workflows/steps/deduct-purchase-points.ts" highlights={deductStepHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import LoyaltyModuleService from "../../modules/loyalty/service" - -type DeductPurchasePointsInput = { - customer_id: string - amount: number -} - -export const deductPurchasePointsStep = createStep( - "deduct-purchase-points", - async ({ - customer_id, amount, - }: DeductPurchasePointsInput, { container }) => { - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const pointsToDeduct = await loyaltyModuleService.calculatePointsFromAmount( - amount - ) - - const result = await loyaltyModuleService.deductPoints( - customer_id, - pointsToDeduct - ) - - return new StepResponse(result, { - customer_id, - points: pointsToDeduct, - }) - }, - async (data, { container }) => { - if (!data) { - return - } - - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - // Restore points in case of failure - await loyaltyModuleService.addPoints( - data.customer_id, - data.points - ) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `customer_id`: The ID of the customer to deduct points from. -- `amount`: The promotion's amount, which will be used to calculate the points to deduct. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to deduct from the promotion's amount. - -After that, you call the `deductPoints` method to deduct the points from the customer's loyalty points. - -Finally, you return a `StepResponse` with the result of the `deductPoints`. - -#### Compensation Function - -This step has a compensation function, which is passed as a third parameter to the `createStep` function. - -The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. - -The compensation function accepts two parameters: - -1. Data passed from the step function to the compensation function. The data is passed as a second parameter of the returned `StepResponse` instance. -2. An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). - -In the compensation function, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `addPoints` method to restore the points deducted from the customer's loyalty points if an error occurs. - -### addPurchaseAsPointsStep - -The last step you'll create adds points to the customer's loyalty points. You'll use this step if the customer didn't redeem points during checkout. - -To create the step, create the file `src/workflows/steps/add-purchase-as-points.ts` with the following content: - -```ts title="src/workflows/steps/add-purchase-as-points.ts" highlights={addPointsHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import LoyaltyModuleService from "../../modules/loyalty/service" - -type StepInput = { - customer_id: string - amount: number -} - -export const addPurchaseAsPointsStep = createStep( - "add-purchase-as-points", - async (input: StepInput, { container }) => { - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const pointsToAdd = await loyaltyModuleService.calculatePointsFromAmount( - input.amount - ) - - const result = await loyaltyModuleService.addPoints( - input.customer_id, - pointsToAdd - ) - - return new StepResponse(result, { - customer_id: input.customer_id, - points: pointsToAdd, - }) - }, - async (data, { container }) => { - if (!data) { - return - } - - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - await loyaltyModuleService.deductPoints( - data.customer_id, - data.points - ) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `customer_id`: The ID of the customer to add points to. -- `amount`: The order's amount, which will be used to calculate the points to add. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to add from the order's amount. - -After that, you call the `addPoints` method to add the points to the customer's loyalty points. - -Finally, you return a `StepResponse` with the result of the `addPoints`. - -You also pass to the compensation function the customer's ID and the points added. In the compensation function, you deduct the points if an error occurs. - -### Add Utility Functions - -Before you create the workflow, you need a utility function that checks whether an order's cart has a loyalty promotion. This is useful to determine whether the customer redeemed points during checkout, allowing you to decide which steps to execute. - -To add the utility function, add the following to `src/utils/promo.ts`: - -```ts title="src/utils/promo.ts" -import { OrderDTO } from "@medusajs/framework/types" - -export type OrderData = OrderDTO & { - promotion?: PromotionDTO[] - customer?: CustomerDTO - cart?: CartData -} - -export const CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE = "customer_id" - -export function orderHasLoyaltyPromotion(order: OrderData): boolean { - const loyaltyPromotion = getCartLoyaltyPromotion( - order.cart as unknown as CartData - ) - - return loyaltyPromotion?.rules?.some((rule) => { - return rule?.attribute === CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE && ( - rule?.values?.some((value) => value.value === order.customer?.id) || false - ) - }) || false -} -``` - -You first define an `OrderData` type that extends the `OrderDTO` type. This type has the order's details, including the cart, customer, and promotions details. - -Then, you define a constant `CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE` that represents the attribute used in the promotion rule to check whether the customer ID is valid. - -Finally, you create the `orderHasLoyaltyPromotion` function that accepts an order's details and checks whether it has a loyalty promotion. It returns `true` if: - -- The order's cart has a loyalty promotion. You use the `getCartLoyaltyPromotion` utility to try to retrieve the loyalty promotion. -- The promotion's rules include the `customer_id` attribute and its value matches the order's customer ID. - - When you create the promotion for the cart later, you'll see how to set this rule. - -You'll use this utility in the workflow next. - -### Create the Workflow - -Now that you have all the steps, you can create the workflow that uses them. - -To create the workflow, create the file `src/workflows/handle-order-points.ts` with the following content: - -```ts title="src/workflows/handle-order-points.ts" highlights={handleOrderPointsHighlights} collapsibleLines="1-9" expandButtonLabel="Show Imports" -import { createWorkflow, when } from "@medusajs/framework/workflows-sdk" -import { updatePromotionsStep, useQueryGraphStep } from "@medusajs/medusa/core-flows" -import { validateCustomerExistsStep, ValidateCustomerExistsStepInput } from "./steps/validate-customer-exists" -import { deductPurchasePointsStep } from "./steps/deduct-purchase-points" -import { addPurchaseAsPointsStep } from "./steps/add-purchase-as-points" -import { OrderData, CartData } from "../utils/promo" -import { orderHasLoyaltyPromotion } from "../utils/promo" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" - -type WorkflowInput = { - order_id: string -} - -export const handleOrderPointsWorkflow = createWorkflow( - "handle-order-points", - ({ order_id }: WorkflowInput) => { - // @ts-ignore - const { data: orders } = useQueryGraphStep({ - entity: "order", - fields: [ - "id", - "customer.*", - "total", - "cart.*", - "cart.promotions.*", - "cart.promotions.rules.*", - "cart.promotions.rules.values.*", - "cart.promotions.application_method.*", - ], - filters: { - id: order_id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - validateCustomerExistsStep({ - customer: orders[0].customer, - } as ValidateCustomerExistsStepInput) - - const loyaltyPointsPromotion = getCartLoyaltyPromoStep({ - cart: orders[0].cart as unknown as CartData, - }) - - when(orders, (orders) => - orderHasLoyaltyPromotion(orders[0] as unknown as OrderData) && - loyaltyPointsPromotion !== undefined - ) - .then(() => { - deductPurchasePointsStep({ - customer_id: orders[0].customer!.id, - amount: loyaltyPointsPromotion.application_method!.value as number, - }) - - updatePromotionsStep([ - { - id: loyaltyPointsPromotion.id, - status: "inactive", - }, - ]) - }) - - - when( - orders, - (order) => !orderHasLoyaltyPromotion(order[0] as unknown as OrderData) - ) - .then(() => { - addPurchaseAsPointsStep({ - customer_id: orders[0].customer!.id, - amount: orders[0].total, - }) - }) - } -) -``` - -You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. - -It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an object with the order's ID. - -In the workflow's constructor function, you: - -- Use `useQueryGraphStep` to retrieve the order's details. You pass the order's ID as a filter to retrieve the order. - - This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules. -- Validate that the customer is registered using the `validateCustomerExistsStep`. -- Retrieve the cart's loyalty promotion using the `getCartLoyaltyPromoStep`. -- Use `when` to check whether the order's cart has a loyalty promotion. - - Since you can't perform data manipulation in a workflow's constructor function, `when` allows you to perform steps if a condition is satisfied. - - You pass as a first parameter the object to perform the condition on, which is the order in this case. In the second parameter, you pass a function that returns a boolean value, indicating whether the condition is satisfied. - - To specify the steps to perform if a condition is satisfied, you chain a `then` method to the `when` method. You can perform any step within the `then` method. - - In this case, if the order's cart has a loyalty promotion, you call the `deductPurchasePointsStep` to deduct points from the customer's loyalty points. You also call the `updatePromotionsStep` to deactivate the cart's loyalty promotion. -- You use another `when` to check whether the order's cart doesn't have a loyalty promotion. - - If the condition is satisfied, you call the `addPurchaseAsPointsStep` to add points to the customer's loyalty points. - -You'll use this workflow next when an order is placed. - -To learn more about the constraints on a workflow's constructor function, refer to the [Workflow Constraints](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md) documentation. Refer to the [When-Then](https://docs.medusajs.com/docs/learn/fundamentals/workflows/conditions/index.html.md) documentation to learn more about the `when` method and how to use it in a workflow. - -*** - -## Step 4: Handle Order Placed Event - -Now that you have the workflow that handles adding or deducting loyalty points for an order, you need to execute it when an order is placed. - -Medusa has an event system that allows you to listen to events emitted by the Medusa server using a [subscriber](https://docs.medusajs.com/docs//learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that's executed when its associated event is emitted. In a subscriber, you can execute a workflow that performs actions in result of the event. - -In this step, you'll create a subscriber that listens to the `order.placed` event and executes the `handleOrderPointsWorkflow` workflow. - -Refer to the [Events and Subscribers](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md) documentation to learn more. - -Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, to create a subscriber, create the fle `src/subscribers/order-placed.ts` with the following content: - -```ts title="src/subscribers/order-placed.ts" -import type { - SubscriberArgs, - SubscriberConfig, -} from "@medusajs/framework" -import { handleOrderPointsWorkflow } from "../workflows/handle-order-points" - -export default async function orderPlacedHandler({ - event: { data }, - container, -}: SubscriberArgs<{ id: string }>) { - await handleOrderPointsWorkflow(container).run({ - input: { - order_id: data.id, - }, - }) -} - -export const config: SubscriberConfig = { - event: "order.placed", -} -``` - -The subscriber file must export: - -- An asynchronous subscriber function that's executed whenever the associated event, which is `order.placed` is triggered. -- A configuration object with an event property whose value is the event the subscriber is listening to. You can also pass an array of event names to listen to multiple events in the same subscriber. - -The subscriber function accepts an object with the following properties: - -- `event`: An object with the event's data payload. For example, the `order.placed` event has the order's ID in its data payload. -- `container`: The Medusa container, which you can use to resolve services and tools. - -In the subscriber function, you execute the `handleOrderPointsWorkflow` by invoking it, passing it the Medusa container, then using its `run` method, passing it the workflow's input. - -Whenever an order is placed now, the subscriber will be executed, which in turn will execute the workflow that handles the loyalty points flow. - -### Test it Out - -To test out the loyalty points flow, you'll use the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) that you installed in the first step. As mentioned in that step, the storefront will be installed in a separate directory from the Medusa application, and its name is `{project-name}-storefront`, where `{project-name}` is the name of your Medusa application's directory. - -So, run the following command in the Medusa application's directory to start the Medusa server: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm run dev -``` - -Then, run the following command in the Next.js Starter Storefront's directory to start the Next.js server: - -```bash npm2yarn badgeLabel="Storefront" badgeColor="blue" -npm run dev -``` - -The Next.js Starter Storefront will be running on `http://localhost:8000`, and the Medusa server will be running on `http://localhost:9000`. - -Open the Next.js Starter Storefront in your browser and create a new account by going to Account at the top right. - -Once you're logged in, add an item to the cart and go through the checkout flow. - -After you place the order, you'll see the following message in your Medusa application's terminal: - -```bash -info: Processing order.placed which has 1 subscribers -``` - -This message indicates that the `order.placed` event was emitted, and that your subscriber was executed. - -Since you didn't redeem any points during checkout, loyalty points will be added to your account. You'll implement an API route that allows you to retrieve the loyalty points in the next step. - -*** - -## Step 5: Retrieve Loyalty Points API Route - -Next, you want to allow customers to view their loyalty points. You can show them on their profile page, or during checkout. - -To expose a feature to clients, you create an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. - -You'll create an API route at the path `/store/customers/me/loyalty-points` that returns the loyalty points of the authenticated customer. - -Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). - -An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`. - -So, to create an API route at the path `/store/customers/me/loyalty-points`, create the file `src/api/store/customers/me/loyalty-points/route.ts` with the following content: - -```ts title="src/api/store/customers/me/loyalty-points/route.ts" - -import { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { LOYALTY_MODULE } from "../../../../../modules/loyalty" -import LoyaltyModuleService from "../../../../../modules/loyalty/service" - -export async function GET( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) { - const loyaltyModuleService: LoyaltyModuleService = req.scope.resolve( - LOYALTY_MODULE - ) - - const points = await loyaltyModuleService.getPoints( - req.auth_context.actor_id - ) - - res.json({ - points, - }) -} -``` - -Since you export a `GET` route handler function, you're exposing a `GET` endpoint at `/store/customers/me/loyalty-points`. The route handler function accepts two parameters: - -1. A request object with details and context on the request, such as body parameters or authenticated customer details. -2. A response object to manipulate and send the response. - -In the route handler, you resolve the Loyalty Module's service from the Medusa container (which is available at `req.scope`). - -Then, you call the service's `getPoints` method to retrieve the authenticated customer's loyalty points. Note that routes starting with `/store/customers/me` are only accessible by authenticated customers. You can access the authenticated customer ID from the request's context, which is available at `req.auth_context.actor_id`. - -Finally, you return the loyalty points in the response. - -You'll test out this route as you customize the Next.js Starter Storefront next. - -*** - -## Step 6: Show Loyalty Points During Checkout - -Now that you have the API route to retrieve the loyalty points, you can show them during checkout. - -In this step, you'll customize the Next.js Starter Storefront to show the loyalty points in the checkout page. - -First, you'll add a server action function that retrieves the loyalty points from the route you created earlier. In `src/lib/data/customer.ts`, add the following function: - -```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" -export const getLoyaltyPoints = async () => { - const headers = { - ...(await getAuthHeaders()), - } - - return sdk.client.fetch<{ points: number }>( - `/store/customers/me/loyalty-points`, - { - method: "GET", - headers, - } - ) - .then(({ points }) => points) - .catch(() => null) -} -``` - -You add a `getLoyaltyPoints` function that retrieves the authenticated customer's loyalty points from the API route you created earlier. You pass the authentication headers using the `getAuthHeaders` function, which is a utility function defined in the Next.js Starter Storefront. - -If the customer isn't authenticated, the request will fail. So, you catch the error and return `null` in that case. - -Next, you'll create a component that shows the loyalty points in the checkout page. Create the file `src/modules/checkout/components/loyalty-points/index.tsx` with the following content: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={loyaltyPointsHighlights} -"use client" - -import { HttpTypes } from "@medusajs/types" -import { useEffect, useMemo, useState } from "react" -import { getLoyaltyPoints } from "../../../../lib/data/customer" -import { Button, Heading } from "@medusajs/ui" -import Link from "next/link" - -type LoyaltyPointsProps = { - cart: HttpTypes.StoreCart & { - promotions: HttpTypes.StorePromotion[] - } -} - -const LoyaltyPoints = ({ cart }: LoyaltyPointsProps) => { - const isLoyaltyPointsPromoApplied = useMemo(() => { - return cart.promotions.find( - (promo) => promo.id === cart.metadata?.loyalty_promo_id - ) !== undefined - }, [cart]) - const [loyaltyPoints, setLoyaltyPoints] = useState< - number | null - >(null) - - useEffect(() => { - getLoyaltyPoints() - .then((points) => { - console.log(points) - setLoyaltyPoints(points) - }) - }, []) - - const handleTogglePromotion = async ( - e: React.MouseEvent - ) => { - e.preventDefault() - // TODO apply or remove loyalty promotion - } - - return ( - <> -
-
- - Loyalty Points - - {loyaltyPoints === null && ( - - Sign up to get and use loyalty points - - )} - {loyaltyPoints !== null && ( -
- - - You have {loyaltyPoints} loyalty points - -
- )} -
- - ) -} - -export default LoyaltyPoints -``` - -You create a `LoyaltyPoints` component that accepts the cart's details as a prop. In the component, you: - -- Create a `isLoyaltyPointsPromoApplied` memoized value that checks whether the cart has a loyalty promotion applied. You use the `cart.metadata.loyalty_promo_id` property to check this. -- Create a `loyaltyPoints` state to store the customer's loyalty points. -- Call the `getLoyaltyPoints` function in a `useEffect` hook to retrieve the loyalty points from the API route you created earlier. You set the `loyaltyPoints` state with the retrieved points. -- Define `handleTogglePromotion` that, when clicked, would either apply or remove the promotion. You'll implement these functionalities later. -- Render the loyalty points in the component. If the customer isn't authenticated, you show a link to the account page to sign up. Otherwise, you show the loyalty points and a button to apply or remove the promotion. - -Next, you'll show this component at the end of the checkout's summary component. So, import the component in `src/modules/checkout/templates/checkout-summary/index.tsx`: - -```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import LoyaltyPoints from "../../components/loyalty-points" -``` - -Then, in the return statement of the `CheckoutSummary` component, add the following after the `div` wrapping the `DiscountCode`: - -```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" - -``` - -This will show the loyalty points component at the end of the checkout summary. - -### Test it Out - -To test out the customizations to the checkout flow, make sure both the Medusa application and Next.js Starter Storefront are running. - -Then, as an authenticated customer, add an item to cart and proceed to checkout. You'll find a new "Loyalty Points" section at the end of the checkout summary. - -![Loyalty Points Section at the end of the summary section at the right](https://res.cloudinary.com/dza7lstvk/image/upload/v1744195223/Medusa%20Resources/Screenshot_2025-04-09_at_1.39.34_PM_l5oltc.png) - -If you made a purchase before, you can see your loyalty points. You'll also see the "Apply Loyalty Points" button, which doesn't yet do anything. You'll add the functionality next. - -*** - -## Step 7: Apply Loyalty Points to Cart - -The next feature you'll implement allows the customer to apply their loyalty points during checkout. To implement the feature, you need: - -- A workflow that implements the steps of the apply loyalty points flow. -- An API route that exposes the workflow's functionality to clients. You'll then send a request to this API route to apply the loyalty points on the customer's cart. -- A function in the Next.js Starter Storefront that sends the request to the API route you created earlier. - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details. -- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. -- [getCartLoyaltyPromoAmountStep](#getCartLoyaltyPromoAmountStep): Get the amount to be discounted based on the loyalty points. -- [createPromotionsStep](https://docs.medusajs.com/references/medusa-workflows/steps/createPromotionsStep/index.html.md): Create a new loyalty promotion for the cart. -- [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/workflows/updateCartPromotionsWorkflow/index.html.md): Update the cart's promotions with the new loyalty promotion. -- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to store the ID of the loyalty promotion in the metadata. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details again. - -Most of the workflow's steps are either provided by Medusa in the `@medusajs/medusa/core-flows` package or steps you've already implemented. You only need to implement the `getCartLoyaltyPromoAmountStep` step. - -### getCartLoyaltyPromoAmountStep - -The fourth step in the workflow is the `getCartLoyaltyPromoAmountStep`, which retrieves the amount to be discounted based on the loyalty points. This step is useful to determine how much discount to apply to the cart. - -To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo-amount.ts` with the following content: - -```ts title="src/workflows/steps/get-cart-loyalty-promo-amount.ts" highlights={getCartLoyaltyPromoAmountStepHighlights} -import { PromotionDTO, CustomerDTO } from "@medusajs/framework/types" -import { MedusaError } from "@medusajs/framework/utils" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import LoyaltyModuleService from "../../modules/loyalty/service" -import { LOYALTY_MODULE } from "../../modules/loyalty" - -export type GetCartLoyaltyPromoAmountStepInput = { - cart: { - id: string - customer: CustomerDTO - promotions?: PromotionDTO[] - total: number - } -} - -export const getCartLoyaltyPromoAmountStep = createStep( - "get-cart-loyalty-promo-amount", - async ({ cart }: GetCartLoyaltyPromoAmountStepInput, { container }) => { - // Check if customer has any loyalty points - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - const loyaltyPoints = await loyaltyModuleService.getPoints( - cart.customer.id - ) - - if (loyaltyPoints <= 0) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer has no loyalty points" - ) - } - - const pointsAmount = await loyaltyModuleService.calculatePointsFromAmount( - loyaltyPoints - ) - - const amount = Math.min(pointsAmount, cart.total) - - return new StepResponse(amount) - } -) -``` - -You create a step that accepts an object having the cart's details. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `getPoints` method to retrieve the customer's loyalty points. If the customer has no loyalty points, you throw an error. - -Next, you call the `calculatePointsFromAmount` method to calculate the amount to be discounted based on the loyalty points. You use the `Math.min` function to ensure that the amount doesn't exceed the cart's total. - -Finally, you return a `StepResponse` with the amount to be discounted. - -### Create the Workflow - -You can now create the workflow that applies a loyalty promotion to the cart. - -To create the workflow, create the file `src/workflows/apply-loyalty-on-cart.ts` with the following content: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={applyLoyaltyOnCartWorkflowHighlights} collapsibleLines="1-24" expandButtonLabel="Show Imports" -import { - createWorkflow, - transform, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - createPromotionsStep, - updateCartPromotionsWorkflow, - updateCartsStep, - useQueryGraphStep, -} from "@medusajs/medusa/core-flows" -import { - validateCustomerExistsStep, - ValidateCustomerExistsStepInput, -} from "./steps/validate-customer-exists" -import { - getCartLoyaltyPromoAmountStep, - GetCartLoyaltyPromoAmountStepInput, -} from "./steps/get-cart-loyalty-promo-amount" -import { CartData, CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE } from "../utils/promo" -import { CreatePromotionDTO } from "@medusajs/framework/types" -import { PromotionActions } from "@medusajs/framework/utils" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" - -type WorkflowInput = { - cart_id: string -} - -const fields = [ - "id", - "customer.*", - "promotions.*", - "promotions.application_method.*", - "promotions.rules.*", - "promotions.rules.values.*", - "currency_code", - "total", - "metadata", -] - -export const applyLoyaltyOnCartWorkflow = createWorkflow( - "apply-loyalty-on-cart", - (input: WorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { - id: input.cart_id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - validateCustomerExistsStep({ - customer: carts[0].customer, - } as ValidateCustomerExistsStepInput) - - getCartLoyaltyPromoStep({ - cart: carts[0] as unknown as CartData, - throwErrorOn: "found", - }) - - const amount = getCartLoyaltyPromoAmountStep({ - cart: carts[0], - } as unknown as GetCartLoyaltyPromoAmountStepInput) - - // TODO create and apply the promotion on the cart - } -) -``` - -You create a workflow that accepts an object with the cart's ID as input. - -So far, you: - -- Use `useQueryGraphStep` to retrieve the cart's details. You pass the cart's ID as a filter to retrieve the cart. -- Validate that the customer is registered using the `validateCustomerExistsStep`. -- Check whether the cart has a loyalty promotion using the `getCartLoyaltyPromoStep`. You pass the `throwErrorOn` parameter with the value `found` to throw an error if a loyalty promotion is found in the cart. -- Retrieve the amount to be discounted based on the loyalty points using the `getCartLoyaltyPromoAmountStep`. - -Next, you need to create a new loyalty promotion for the cart. First, you'll prepare the data of the promotion to be created. - -Replace the `TODO` with the following: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={prepareLoyaltyPromoDataHighlights} -const promoToCreate = transform({ - carts, - amount, -}, (data) => { - const randomStr = Math.random().toString(36).substring(2, 8) - const uniqueId = ( - "LOYALTY-" + data.carts[0].customer?.first_name + "-" + randomStr - ).toUpperCase() - return { - code: uniqueId, - type: "standard", - status: "active", - application_method: { - type: "fixed", - value: data.amount, - target_type: "order", - currency_code: data.carts[0].currency_code, - allocation: "across", - }, - rules: [ - { - attribute: CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE, - operator: "eq", - values: [data.carts[0].customer!.id], - }, - ], - campaign: { - name: uniqueId, - description: "Loyalty points promotion for " + data.carts[0].customer!.email, - campaign_identifier: uniqueId, - budget: { - type: "usage", - limit: 1, - }, - }, - } -}) - -// TODO create promotion and apply it on cart -``` - -Since data manipulation isn't allowed in a workflow constructor, you use the [transform](https://docs.medusajs.com/docs/learn/fundamentals/workflows/variable-manipulation/index.html.md) function from the Workflows SDK. It accepts two parameters: - -- The data to perform manipulation on. In this case, you pass the cart's details and the amount to be discounted. -- A function that receives the data from the first parameter, and returns the transformed data. - -In the transformation function, you prepare th data of the loyalty promotion to be created. Some key details include: - -- You set the discount amount in the application method of the promotion. -- You add a rule to the promotion that ensures it can be used only in carts having their `customer_id` equal to this customer's ID. This prevents other customers from using this promotion. -- You create a campaign for the promotion, and you set the campaign budget to a single usage. This prevents the customer from using the promotion again. - -Learn more about promotion concepts in the [Promotion Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/index.html.md)'s documentation. - -You can now use the returned data to create a promotion and apply it to the cart. Replace the new `TODO` with the following: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={createLoyaltyPromoStepHighlights} -const loyaltyPromo = createPromotionsStep([ - promoToCreate, -] as CreatePromotionDTO[]) - -const { metadata, ...updatePromoData } = transform({ - carts, - promoToCreate, - loyaltyPromo, -}, (data) => { - const promos = [ - ...(data.carts[0].promotions?.map((promo) => promo?.code).filter(Boolean) || []) as string[], - data.promoToCreate.code, - ] - - return { - cart_id: data.carts[0].id, - promo_codes: promos, - action: PromotionActions.ADD, - metadata: { - loyalty_promo_id: data.loyaltyPromo[0].id, - }, - } -}) - -updateCartPromotionsWorkflow.runAsStep({ - input: updatePromoData, -}) - -updateCartsStep([ - { - id: input.cart_id, - metadata, - }, -]) - -// retrieve cart with updated promotions -// @ts-ignore -const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { id: input.cart_id }, -}).config({ name: "retrieve-cart" }) - -return new WorkflowResponse(updatedCarts[0]) -``` - -In the rest of the workflow, you: - -- Create the loyalty promotion using the data you prepared earlier using the `createPromotionsStep`. -- Use the `transform` function to prepare the data to update the cart's promotions. You add the new loyalty promotion code to the cart's promotions codes, and set the `loyalty_promo_id` in the cart's metadata. -- Update the cart's promotions with the new loyalty promotion using the `updateCartPromotionsWorkflow` workflow. -- Update the cart's metadata with the loyalty promotion ID using the `updateCartsStep`. -- Retrieve the cart's details again using `useQueryGraphStep` to get the updated cart with the new loyalty promotion. - -To return data from the workflow, you must return an instance of `WorkflowResponse`. You pass it the data to be returned, which is in this case the cart's details. - -### Create the API Route - -Next, you'll create the API route that executes this workflow. - -To create the API route, create the file `src/api/store/carts/[id]/loyalty-points/route.ts` with the following content: - -```ts title="src/api/store/carts/[id]/loyalty-points/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" -import { applyLoyaltyOnCartWorkflow } from "../../../../../workflows/apply-loyalty-on-cart" - -export async function POST( - req: MedusaRequest, - res: MedusaResponse -) { - const { id: cart_id } = req.params - - const { result: cart } = await applyLoyaltyOnCartWorkflow(req.scope) - .run({ - input: { - cart_id, - }, - }) - - res.json({ cart }) -} -``` - -Since you export a `POST` route handler, you expose a `POST` API route at `/store/carts/[id]/loyalty-points`. - -In the route handler, you execute the `applyLoyaltyOnCartWorkflow` workflow, passing it the cart ID as an input. You return the cart's details in the response. - -You can now use this API route in the Next.js Starter Storefront. - -### Apply Loyalty Points in the Storefront - -In the Next.js Starter Storefront, you need to add a server action function that sends a request to the API route you created earlier.

Once the request is resolved successfully, you revalidate the cart cache tag to ensure that the cart's details are updated and refetched by other components. This ensures that the applied promotion is shown in the checkout summary without needing to refresh the page. - -Finally, you'll use this function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. - -At the top of `src/modules/checkout/components/loyalty-points/index.tsx`, import the function: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import { applyLoyaltyPointsOnCart } from "../../../../lib/data/cart" -``` - -Then, replace the `handleTogglePromotion` function with the following: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const handleTogglePromotion = async ( - e: React.MouseEvent -) => { - e.preventDefault() - if (!isLoyaltyPointsPromoApplied) { - await applyLoyaltyPointsOnCart() - } else { - // TODO remove loyalty points - } -} -``` - -In the `handleTogglePromotion` function, you call the `applyLoyaltyPointsOnCart` function if the cart doesn't have a loyalty promotion. This will send a request to the API route you created earlier, which will execute the workflow that applies the loyalty promotion to the cart. - -You'll implement removing the loyalty points promotion in a later step. - -### Test it Out - -To test out applying the loyalty points on the cart, start the Medusa application and Next.js Starter Storefront. - -Then, in the checkout flow as an authenticated customer, click on the "Apply Loyalty Points" button. The checkout summary will be updated with the applied promotion and the discount amount. - -If you don't want the promotion to be shown in the "Promotions(s) applied" section, you can filter the promotions in `src/modules/checkout/components/discount-code/index.tsx` to not show a promotion matching `cart.metadata.loyalty_promo_id`. - -![Discounted amount is shown as part of the summary and the promotion is shown as part of the applied promotions](https://res.cloudinary.com/dza7lstvk/image/upload/v1744200895/Medusa%20Resources/Screenshot_2025-04-09_at_3.14.19_PM_abmtjh.png) - -*** - -## Step 8: Remove Loyalty Points From Cart - -In this step, you'll implement the functionality to remove the loyalty points promotion from the cart. This is useful if the customer changes their mind and wants to remove the promotion. - -To implement this functionality, you'll need to: - -- Create a workflow that removes the loyalty points promotion from the cart. -- Create an API route that executes the workflow. -- Create a function in the Next.js Starter Storefront that sends a request to the API route you created earlier. -- Use the function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. - -### Create the Workflow - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. -- [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/workflows/updateCartPromotionsWorkflow/index.html.md): Update the cart's promotions to remove the loyalty promotion. -- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to remove the loyalty promotion ID from the metadata. -- [updatePromotionsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updatePromotionsStep/index.html.md): Deactive the loyalty promotion. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details again. - -Since you already have all the steps, you can create the workflow. - -To create the workflow, create the file `src/workflows/remove-loyalty-from-cart.ts` with the following content: - -```ts title="src/workflows/remove-loyalty-from-cart.ts" collapsibleLines="1-15" expandButtonLabel="Show Imports" highlights={removeLoyaltyFromCartWorkflowHighlights} -import { - createWorkflow, - transform, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - useQueryGraphStep, - updateCartPromotionsWorkflow, - updateCartsStep, - updatePromotionsStep, -} from "@medusajs/medusa/core-flows" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" -import { PromotionActions } from "@medusajs/framework/utils" -import { CartData } from "../utils/promo" - -type WorkflowInput = { - cart_id: string -} - -const fields = [ - "id", - "customer.*", - "promotions.*", - "promotions.application_method.*", - "promotions.rules.*", - "promotions.rules.values.*", - "currency_code", - "total", - "metadata", -] - -export const removeLoyaltyFromCartWorkflow = createWorkflow( - "remove-loyalty-from-cart", - (input: WorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { - id: input.cart_id, - }, - }) - - const loyaltyPromo = getCartLoyaltyPromoStep({ - cart: carts[0] as unknown as CartData, - throwErrorOn: "not-found", - }) - - updateCartPromotionsWorkflow.runAsStep({ - input: { - cart_id: input.cart_id, - promo_codes: [loyaltyPromo.code!], - action: PromotionActions.REMOVE, - }, - }) - - const newMetadata = transform({ - carts, - }, (data) => { - const { loyalty_promo_id, ...rest } = data.carts[0].metadata || {} - - return { - ...rest, - loyalty_promo_id: null, - } - }) - - updateCartsStep([ - { - id: input.cart_id, - metadata: newMetadata, - }, - ]) - - updatePromotionsStep([ - { - id: loyaltyPromo.id, - status: "inactive", - }, - ]) - - // retrieve cart with updated promotions - // @ts-ignore - const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { id: input.cart_id }, - }).config({ name: "retrieve-cart" }) - - return new WorkflowResponse(updatedCarts[0]) - } -) -``` - -You create a workflow that accepts an object with the cart's ID as input. - -In the workflow, you: - -- Use `useQueryGraphStep` to retrieve the cart's details.

This workflow has a `validate` hook that allows you to perform custom validation before the cart is completed. - -To consume the `validate` hook, create the file `src/workflows/hooks/complete-cart.ts` with the following content: - -```ts title="src/workflows/hooks/complete-cart.ts" highlights={completeCartWorkflowHookHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" -import { completeCartWorkflow } from "@medusajs/medusa/core-flows" -import LoyaltyModuleService from "../../modules/loyalty/service" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" -import { MedusaError } from "@medusajs/framework/utils" - -completeCartWorkflow.hooks.validate( - async ({ cart }, { container }) => { - const query = container.resolve("query") - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const { data: carts } = await query.graph({ - entity: "cart", - fields: [ - "id", - "promotions.*", - "customer.*", - "promotions.rules.*", - "promotions.rules.values.*", - "promotions.application_method.*", - "metadata", - ], - filters: { - id: cart.id, - }, - }, { - throwIfKeyNotFound: true, - }) - - const loyaltyPromo = getCartLoyaltyPromotion( - carts[0] as unknown as CartData - ) - - if (!loyaltyPromo) { - return - } - - const customerLoyaltyPoints = await loyaltyModuleService.getPoints( - carts[0].customer!.id - ) - const requiredPoints = await loyaltyModuleService.calculatePointsFromAmount( - loyaltyPromo.application_method!.value as number - ) - - if (customerLoyaltyPoints < requiredPoints) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - `Customer does not have enough loyalty points. Required: ${ - requiredPoints - }, Available: ${customerLoyaltyPoints}` - ) - } - } -) -``` - -Workflows have a special `hooks` property that includes all the hooks tht you can consume in that workflow. You consume the hook by invoking it from the workflow's `hooks` property. - -Since the hook is essentially a step function, it accepts the following parameters: - -- The hook's input passed from the workflow, which differs for each hook. The `validate` hook receives an object having the cart's details. -- The step context object, which contains the Medusa container. You can use it to resolve services and perform actions. - -In the hook, you resolve Query and the Loyalty Module's service. Then, you use Query to retrieve the cart's necessary details, including its promotions, customer, and metadata. - -After that, you retrieve the customer's loyalty points and calculate the required points to apply the loyalty promotion. - -If the customer doesn't have enough loyalty points, you throw an error. This will prevent the cart from being completed if the customer doesn't have enough loyalty points. - -*** - -## Test Out Cart Completion with Loyalty Points - -Since you now have the entire loyalty points flow implemented, you can test it out by going through the checkout flow, applying the loyalty points to the cart. - -When you place the order, if the customer has sufficient loyalty points, the validation hook will pass. - -Then, the `order.placed` event will be emitted, which will execute the subscriber that calls the `handleOrderPointsWorkflow`. - -In the workflow, since the order's cart has a loyalty promotion, the points equivalent to the promotion will be deducted, and the promotion becomes inactive. - -You can confirm that the loyalty points were deducted either by sending a request to the [retrieve loyalty points API route](#step-5-retrieve-loyalty-points-api-route), or by going through the checkout process again in the storefront. - -*** - -## Next Steps - -You've now implement a loyalty points system in Medusa. There's still more that you can implement based on your use case: - -- Add loyalty points on registration or other events. Refer to the [Events Reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/events-reference/index.html.md) for a full list of available events you can listen to. -- Show the customer their loyalty point usage history. This will require adding another data model in the Loyalty Module that records the usage history. You can create records of that data model when an order that has a loyalty promotion is placed, then customize the storefront to show a new page for loyalty points history. -- Customize the Medusa Admin to show a new page or [UI Route](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md) for loyalty points information and analytics. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - # Implement Product Reviews in Medusa In this tutorial, you'll learn how to implement product reviews in Medusa. @@ -44647,6 +43064,1797 @@ If you're new to Medusa, check out the [main documentation](https://docs.medusaj To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). +# Implement Loyalty Points System in Medusa + +In this tutorial, you'll learn how to implement a loyalty points system in Medusa. + +Medusa Cloud provides a beta Store Credits feature that facilitates building a loyalty point system. [Get in touch](https://medusajs.com/contact) for early access. + +When you install a Medusa application, you get a fully-fledged commerce platform with a Framework for customization. The Medusa application's commerce features are built around [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md), which are available out-of-the-box. These features include management capabilities related to carts, orders, promotions, and more. + +A loyalty point system allows customers to earn points for purchases, which can be redeemed for discounts or rewards. In this tutorial, you'll learn how to customize the Medusa application to implement a loyalty points system. + +You can follow this tutorial whether you're new to Medusa or an advanced Medusa developer. + +## Summary + +By following this tutorial, you will learn how to: + +- Install and set up Medusa. +- Define models to store loyalty points and the logic to manage them. +- Build flows that allow customers to earn and redeem points during checkout. + - Points are redeemed through dynamic promotions specific to the customer. +- Customize the cart completion flow to validate applied loyalty points. + +![Diagram illustrating redeem loyalty points flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1744126213/Medusa%20Resources/redeem-points-flow_kzgkux.jpg) + +- [Loyalty Points Repository](https://github.com/medusajs/examples/tree/main/loyalty-points): Find the full code for this guide in this repository. +- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1744212595/OpenApi/Loyalty-Points_jwi5e9.yaml): Import this OpenApi Specs file into tools like Postman. + +*** + +## Step 1: Install a Medusa Application + +### Prerequisites + +- [Node.js v20+](https://nodejs.org/en/download) +- [Git CLI tool](https://git-scm.com/downloads) +- [PostgreSQL](https://www.postgresql.org/download/) + +Start by installing the Medusa application on your machine with the following command: + +```bash +npx create-medusa-app@latest +``` + +You'll first be asked for the project's name. Then, when asked whether you want to install the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md), choose Yes. + +Afterward, the installation process will start, which will install the Medusa application in a directory with your project's name, and the Next.js Starter Storefront in a separate directory with the `{project-name}-storefront` name. + +The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more in [Medusa's Architecture documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). + +Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user. Enter the user's credentials and submit the form.

A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. + +In the module, you define the data models necessary for a feature and the logic to manage these data models. Later, you can build commerce flows around your module. + +In this step, you'll build a Loyalty Module that defines the necessary data models to store and manage loyalty points for customers. + +Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. + +### Create Module Directory + +Modules are created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/loyalty`. + +### Create Data Models + +A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. + +Refer to the [Data Models documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#1-create-data-model/index.html.md) to learn more. + +For the Loyalty Module, you need to define a `LoyaltyPoint` data model that represents a customer's loyalty points. So, create the file `src/modules/loyalty/models/loyalty-point.ts` with the following content: + +```ts title="src/modules/loyalty/models/loyalty-point.ts" highlights={dmlHighlights} +import { model } from "@medusajs/framework/utils" + +const LoyaltyPoint = model.define("loyalty_point", { + id: model.id().primaryKey(), + points: model.number().default(0), + customer_id: model.text().unique("IDX_LOYALTY_CUSTOMER_ID"), +}) + +export default LoyaltyPoint +``` + +You define the `LoyaltyPoint` data model using the `model.define` method of the DML. It accepts the data model's table name as a first parameter, and the model's schema object as a second parameter. + +The `LoyaltyPoint` data model has the following properties: + +- `id`: A unique ID for the loyalty points. +- `points`: The number of loyalty points a customer has. +- `customer_id`: The ID of the customer who owns the loyalty points. This property has a unique index to ensure that each customer has only one record in the `loyalty_point` table. + +Learn more about defining data model properties in the [Property Types documentation](https://docs.medusajs.com/docs/learn/fundamentals/data-models/properties/index.html.md). + +### Create Module's Service + +You now have the necessary data model in the Loyalty Module, but you'll need to manage its records. You do this by creating a service in the module. + +A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, allowing you to manage your data models, or connect to a third-party service, which is useful if you're integrating with external services. + +Refer to the [Module Service documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#2-create-service/index.html.md) to learn more. + +To create the Loyalty Module's service, create the file `src/modules/loyalty/service.ts` with the following content: + +```ts title="src/modules/loyalty/service.ts" +import { MedusaError, MedusaService } from "@medusajs/framework/utils" +import LoyaltyPoint from "./models/loyalty-point" +import { InferTypeOf } from "@medusajs/framework/types" + +type LoyaltyPoint = InferTypeOf + +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // TODO add methods +} + +export default LoyaltyModuleService +``` + +The `LoyaltyModuleService` extends `MedusaService` from the Modules SDK which generates a class with data-management methods for your module's data models. This saves you time on implementing Create, Read, Update, and Delete (CRUD) methods. + +So, the `LoyaltyModuleService` class now has methods like `createLoyaltyPoints` and `retrieveLoyaltyPoint`. + +Find all methods generated by the `MedusaService` in [the Service Factory reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/service-factory-reference/index.html.md). + +#### Add Methods to the Service + +Aside from the basic CRUD methods, you need to add methods that handle custom functionalities related to loyalty points. + +First, you need a method that adds loyalty points for a customer. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + async addPoints(customerId: string, points: number): Promise { + const existingPoints = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + if (existingPoints.length > 0) { + return await this.updateLoyaltyPoints({ + id: existingPoints[0].id, + points: existingPoints[0].points + points, + }) + } + + return await this.createLoyaltyPoints({ + customer_id: customerId, + points, + }) + } +} +``` + +You add an `addPoints` method that accepts two parameters: the ID of the customer and the points to add. + +In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method, which is automatically generated by the `MedusaService`. If the customer has existing points, you update them with the new points using the `updateLoyaltyPoints` method. + +Otherwise, if the customer doesn't have existing loyalty points, you create a new record with the `createLoyaltyPoints` method. + +The next method you'll add deducts points from the customer's loyalty points, which is useful when the customer redeems points. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async deductPoints(customerId: string, points: number): Promise { + const existingPoints = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + if (existingPoints.length === 0 || existingPoints[0].points < points) { + throw new MedusaError( + MedusaError.Types.NOT_ALLOWED, + "Insufficient loyalty points" + ) + } + + return await this.updateLoyaltyPoints({ + id: existingPoints[0].id, + points: existingPoints[0].points - points, + }) + } +} +``` + +The `deductPoints` method accepts the customer ID and the points to deduct. + +In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method. If the customer doesn't have existing points or if the points to deduct are greater than the existing points, you throw an error. + +Otherwise, you update the customer's loyalty points with the new value using the `updateLoyaltyPoints` method, which is automatically generated by `MedusaService`. + +Next, you'll add the method that retrieves the points of a customer. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async getPoints(customerId: string): Promise { + const points = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + return points[0]?.points || 0 + } +} +``` + +The `getPoints` method accepts the customer ID and retrieves the customer's loyalty points using the `listLoyaltyPoints` method. If the customer has no points, it returns `0`. + +#### Add Method to Map Points to Discount + +Finally, you'll add a method that implements the logic of mapping loyalty points to a discount amount. This is useful when the customer wants to redeem their points during checkout. + +The mapping logic may differ for each use case. For example, you may need to use a third-party service to map the loyalty points discount amount, or use some custom calculation. + +To simplify the logic in this tutorial, you'll use a simple calculation that maps 1 point to 1 currency unit. For example, `100` points = `$100` discount. + +Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async calculatePointsFromAmount(amount: number): Promise { + // Convert amount to points using a standard conversion rate + // For example, $1 = 1 point + // Round down to nearest whole point + const points = Math.floor(amount) + + if (points < 0) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Amount cannot be negative" + ) + } + + return points + } +} +``` + +The `calculatePointsFromAmount` method accepts the amount and converts it to the nearest whole number of points. If the amount is negative, it throws an error. + +You'll use this method later to calculate the amount discounted when a customer redeems their loyalty points. + +### Export Module Definition + +The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. + +So, create the file `src/modules/loyalty/index.ts` with the following content: + +```ts title="src/modules/loyalty/index.ts" +import { Module } from "@medusajs/framework/utils" +import LoyaltyModuleService from "./service" + +export const LOYALTY_MODULE = "loyalty" + +export default Module(LOYALTY_MODULE, { + service: LoyaltyModuleService, +}) +``` + +You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name, which is `loyalty`. +2. An object with a required property `service` indicating the module's service. + +You also export the module's name as `LOYALTY_MODULE` so you can reference it later. + +### Add Module to Medusa's Configurations + +Once you finish building the module, add it to Medusa's configurations to start using it. + +In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/loyalty", + }, + ], +}) +``` + +Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. + +### Generate Migrations + +Since data models represent tables in the database, you define how they're created in the database with migrations. A migration is a TypeScript or JavaScript file that defines database changes made by a module. + +Refer to the [Migrations documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#5-generate-migrations/index.html.md) to learn more. + +Medusa's CLI tool can generate the migrations for you. To generate a migration for the Loyalty Module, run the following command in your Medusa application's directory: + +```bash +npx medusa db:generate loyalty +``` + +The `db:generate` command of the Medusa CLI accepts the name of the module to generate the migration for. You'll now have a `migrations` directory under `src/modules/loyalty` that holds the generated migration. + +Then, to reflect these migrations on the database, run the following command: + +```bash +npx medusa db:migrate +``` + +The table for the `LoyaltyPoint` data model is now created in the database. + +*** + +## Step 3: Change Loyalty Points Flow + +Now that you have a module that stores and manages loyalty points in the database, you'll start building flows around it that allow customers to earn and redeem points. + +The first flow you'll build will either add points to a customer's loyalty points or deduct them based on a purchased order. If the customer hasn't redeemed points, the points are added to their loyalty points. Otherwise, the points are deducted from their loyalty points. + +To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. + +In this section, you'll build the workflow that adds or deducts loyalty points for an order's customer. Later, you'll execute this workflow when an order is placed. + +Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). + +The workflow will have the following steps: + +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the order's details. +- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. +- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. + +Medusa provides the `useQueryGraphStep` and `updatePromotionsStep` in its `@medusajs/medusa/core-flows` package. So, you'll only implement the other steps. + +### validateCustomerExistsStep + +In the workflow, you first need to validate that the customer is registered. Only registered customers can earn and redeem loyalty points. + +To do this, create the file `src/workflows/steps/validate-customer-exists.ts` with the following content: + +```ts title="src/workflows/steps/validate-customer-exists.ts" +import { CustomerDTO } from "@medusajs/framework/types" +import { createStep } from "@medusajs/framework/workflows-sdk" +import { MedusaError } from "@medusajs/framework/utils" + +export type ValidateCustomerExistsStepInput = { + customer: CustomerDTO | null | undefined +} + +export const validateCustomerExistsStep = createStep( + "validate-customer-exists", + async ({ customer }: ValidateCustomerExistsStepInput) => { + if (!customer) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Customer not found" + ) + } + + if (!customer.has_account) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Customer must have an account to earn or manage points" + ) + } + } +) +``` + +You create a step with `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's unique name, which is `validate-customer-exists`. +2. An async function that receives two parameters: + - The step's input, which is in this case an object with the customer's details. + - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. + +In the step function, you validate that the customer is defined and that it's registered based on its `has_account` property. Otherwise, you throw an error. + +### getCartLoyaltyPromoStep + +Next, you'll need to retrieve the loyalty promotion applied on the cart, if there's any. This is useful to determine whether the customer has redeemed points. + +Before you create a step, you'll create a utility function that the step uses to retrieve the loyalty promotion of a cart. You'll create it as a separate utility function to use it later in other customizations. + +Create the file `src/utils/promo.ts` with the following content: + +```ts title="src/utils/promo.ts" +import { PromotionDTO, CustomerDTO, CartDTO } from "@medusajs/framework/types" + +export type CartData = CartDTO & { + promotions?: PromotionDTO[] + customer?: CustomerDTO + metadata: { + loyalty_promo_id?: string + } +} + +export function getCartLoyaltyPromotion( + cart: CartData +): PromotionDTO | undefined { + if (!cart?.metadata?.loyalty_promo_id) { + return + } + + return cart.promotions?.find( + (promotion) => promotion.id === cart.metadata.loyalty_promo_id + ) +} +``` + +You create a `getCartLoyaltyPromotion` function that accepts the cart's details as an input and returns the loyalty promotion if it exists. You retrieve the loyalty promotion if its ID is stored in the cart's `metadata.loyalty_promo_id` property. + +You can now create the step that uses this utility to retrieve a carts loyalty points promotion. To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo.ts` with the following content: + +```ts title="src/workflows/steps/get-cart-loyalty-promo.ts" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" +import { MedusaError } from "@medusajs/framework/utils" + +type GetCartLoyaltyPromoStepInput = { + cart: CartData, + throwErrorOn?: "found" | "not-found" +} + +export const getCartLoyaltyPromoStep = createStep( + "get-cart-loyalty-promo", + async ({ cart, throwErrorOn }: GetCartLoyaltyPromoStepInput) => { + const loyaltyPromo = getCartLoyaltyPromotion(cart) + + if (throwErrorOn === "found" && loyaltyPromo) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Loyalty promotion already applied to cart" + ) + } else if (throwErrorOn === "not-found" && !loyaltyPromo) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "No loyalty promotion found on cart" + ) + } + + return new StepResponse(loyaltyPromo) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `cart`: The cart's details. +- `throwErrorOn`: An optional property that indicates whether to throw an error if the loyalty promotion is found or not found. + +The `throwErrorOn` property is useful to make the step reusable in different scenarios, allowing you to use it in later workflows. + +In the step, you call the `getCartLoyaltyPromotion` utility to retrieve the loyalty promotion. If the `throwErrorOn` property is set to `found` and the loyalty promotion is found, you throw an error. + +Otherwise, if the `throwErrorOn` property is set to `not-found` and the loyalty promotion is not found, you throw an error. + +To return data from a step, you return an instance of `StepResponse` from the Workflows SDK. It accepts as a parameter the data to return, which is the loyalty promotion in this case. + +### deductPurchasePointsStep + +If the order's cart has a loyalty promotion, you need to deduct points from the customer's loyalty points. To do this, create the file `src/workflows/steps/deduct-purchase-points.ts` with the following content: + +```ts title="src/workflows/steps/deduct-purchase-points.ts" highlights={deductStepHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { LOYALTY_MODULE } from "../../modules/loyalty" +import LoyaltyModuleService from "../../modules/loyalty/service" + +type DeductPurchasePointsInput = { + customer_id: string + amount: number +} + +export const deductPurchasePointsStep = createStep( + "deduct-purchase-points", + async ({ + customer_id, amount, + }: DeductPurchasePointsInput, { container }) => { + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + const pointsToDeduct = await loyaltyModuleService.calculatePointsFromAmount( + amount + ) + + const result = await loyaltyModuleService.deductPoints( + customer_id, + pointsToDeduct + ) + + return new StepResponse(result, { + customer_id, + points: pointsToDeduct, + }) + }, + async (data, { container }) => { + if (!data) { + return + } + + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + // Restore points in case of failure + await loyaltyModuleService.addPoints( + data.customer_id, + data.points + ) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `customer_id`: The ID of the customer to deduct points from. +- `amount`: The promotion's amount, which will be used to calculate the points to deduct. + +In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to deduct from the promotion's amount. + +After that, you call the `deductPoints` method to deduct the points from the customer's loyalty points. + +Finally, you return a `StepResponse` with the result of the `deductPoints`. + +#### Compensation Function + +This step has a compensation function, which is passed as a third parameter to the `createStep` function. + +The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. + +The compensation function accepts two parameters: + +1. Data passed from the step function to the compensation function. The data is passed as a second parameter of the returned `StepResponse` instance. +2. An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). + +In the compensation function, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `addPoints` method to restore the points deducted from the customer's loyalty points if an error occurs. + +### addPurchaseAsPointsStep + +The last step you'll create adds points to the customer's loyalty points. You'll use this step if the customer didn't redeem points during checkout. + +To create the step, create the file `src/workflows/steps/add-purchase-as-points.ts` with the following content: + +```ts title="src/workflows/steps/add-purchase-as-points.ts" highlights={addPointsHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { LOYALTY_MODULE } from "../../modules/loyalty" +import LoyaltyModuleService from "../../modules/loyalty/service" + +type StepInput = { + customer_id: string + amount: number +} + +export const addPurchaseAsPointsStep = createStep( + "add-purchase-as-points", + async (input: StepInput, { container }) => { + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + const pointsToAdd = await loyaltyModuleService.calculatePointsFromAmount( + input.amount + ) + + const result = await loyaltyModuleService.addPoints( + input.customer_id, + pointsToAdd + ) + + return new StepResponse(result, { + customer_id: input.customer_id, + points: pointsToAdd, + }) + }, + async (data, { container }) => { + if (!data) { + return + } + + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + await loyaltyModuleService.deductPoints( + data.customer_id, + data.points + ) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `customer_id`: The ID of the customer to add points to. +- `amount`: The order's amount, which will be used to calculate the points to add. + +In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to add from the order's amount. + +After that, you call the `addPoints` method to add the points to the customer's loyalty points. + +Finally, you return a `StepResponse` with the result of the `addPoints`. + +You also pass to the compensation function the customer's ID and the points added. In the compensation function, you deduct the points if an error occurs. + +### Add Utility Functions + +Before you create the workflow, you need a utility function that checks whether an order's cart has a loyalty promotion. This is useful to determine whether the customer redeemed points during checkout, allowing you to decide which steps to execute. + +To add the utility function, add the following to `src/utils/promo.ts`: + +```ts title="src/utils/promo.ts" +import { OrderDTO } from "@medusajs/framework/types" + +export type OrderData = OrderDTO & { + promotion?: PromotionDTO[] + customer?: CustomerDTO + cart?: CartData +} + +export const CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE = "customer_id" + +export function orderHasLoyaltyPromotion(order: OrderData): boolean { + const loyaltyPromotion = getCartLoyaltyPromotion( + order.cart as unknown as CartData + ) + + return loyaltyPromotion?.rules?.some((rule) => { + return rule?.attribute === CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE && ( + rule?.values?.some((value) => value.value === order.customer?.id) || false + ) + }) || false +} +``` + +You first define an `OrderData` type that extends the `OrderDTO` type. This type has the order's details, including the cart, customer, and promotions details. + +Then, you define a constant `CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE` that represents the attribute used in the promotion rule to check whether the customer ID is valid. + +Finally, you create the `orderHasLoyaltyPromotion` function that accepts an order's details and checks whether it has a loyalty promotion. It returns `true` if: + +- The order's cart has a loyalty promotion. You use the `getCartLoyaltyPromotion` utility to try to retrieve the loyalty promotion. +- The promotion's rules include the `customer_id` attribute and its value matches the order's customer ID. + - When you create the promotion for the cart later, you'll see how to set this rule. + +You'll use this utility in the workflow next. + +### Create the Workflow + +Now that you have all the steps, you can create the workflow that uses them. + +To create the workflow, create the file `src/workflows/handle-order-points.ts` with the following content: + +```ts title="src/workflows/handle-order-points.ts" highlights={handleOrderPointsHighlights} collapsibleLines="1-9" expandButtonLabel="Show Imports" +import { createWorkflow, when } from "@medusajs/framework/workflows-sdk" +import { updatePromotionsStep, useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { validateCustomerExistsStep, ValidateCustomerExistsStepInput } from "./steps/validate-customer-exists" +import { deductPurchasePointsStep } from "./steps/deduct-purchase-points" +import { addPurchaseAsPointsStep } from "./steps/add-purchase-as-points" +import { OrderData, CartData } from "../utils/promo" +import { orderHasLoyaltyPromotion } from "../utils/promo" +import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" + +type WorkflowInput = { + order_id: string +} + +export const handleOrderPointsWorkflow = createWorkflow( + "handle-order-points", + ({ order_id }: WorkflowInput) => { + // @ts-ignore + const { data: orders } = useQueryGraphStep({ + entity: "order", + fields: [ + "id", + "customer.*", + "total", + "cart.*", + "cart.promotions.*", + "cart.promotions.rules.*", + "cart.promotions.rules.values.*", + "cart.promotions.application_method.*", + ], + filters: { + id: order_id, + }, + options: { + throwIfKeyNotFound: true, + }, + }) + + validateCustomerExistsStep({ + customer: orders[0].customer, + } as ValidateCustomerExistsStepInput) + + const loyaltyPointsPromotion = getCartLoyaltyPromoStep({ + cart: orders[0].cart as unknown as CartData, + }) + + when(orders, (orders) => + orderHasLoyaltyPromotion(orders[0] as unknown as OrderData) && + loyaltyPointsPromotion !== undefined + ) + .then(() => { + deductPurchasePointsStep({ + customer_id: orders[0].customer!.id, + amount: loyaltyPointsPromotion.application_method!.value as number, + }) + + updatePromotionsStep([ + { + id: loyaltyPointsPromotion.id, + status: "inactive", + }, + ]) + }) + + + when( + orders, + (order) => !orderHasLoyaltyPromotion(order[0] as unknown as OrderData) + ) + .then(() => { + addPurchaseAsPointsStep({ + customer_id: orders[0].customer!.id, + amount: orders[0].total, + }) + }) + } +) +``` + +You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. + +It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an object with the order's ID. + +In the workflow's constructor function, you: + +- Use `useQueryGraphStep` to retrieve the order's details. You pass the order's ID as a filter to retrieve the order. + - This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules. +- Validate that the customer is registered using the `validateCustomerExistsStep`. +- Retrieve the cart's loyalty promotion using the `getCartLoyaltyPromoStep`. +- Use `when` to check whether the order's cart has a loyalty promotion. + - Since you can't perform data manipulation in a workflow's constructor function, `when` allows you to perform steps if a condition is satisfied. + - You pass as a first parameter the object to perform the condition on, which is the order in this case. In the second parameter, you pass a function that returns a boolean value, indicating whether the condition is satisfied. + - To specify the steps to perform if a condition is satisfied, you chain a `then` method to the `when` method. You can perform any step within the `then` method. + - In this case, if the order's cart has a loyalty promotion, you call the `deductPurchasePointsStep` to deduct points from the customer's loyalty points. You also call the `updatePromotionsStep` to deactivate the cart's loyalty promotion. +- You use another `when` to check whether the order's cart doesn't have a loyalty promotion. + - If the condition is satisfied, you call the `addPurchaseAsPointsStep` to add points to the customer's loyalty points. + +You'll use this workflow next when an order is placed. + +To learn more about the constraints on a workflow's constructor function, refer to the [Workflow Constraints](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md) documentation. Refer to the [When-Then](https://docs.medusajs.com/docs/learn/fundamentals/workflows/conditions/index.html.md) documentation to learn more about the `when` method and how to use it in a workflow. + +*** + +## Step 4: Handle Order Placed Event + +Now that you have the workflow that handles adding or deducting loyalty points for an order, you need to execute it when an order is placed. + +Medusa has an event system that allows you to listen to events emitted by the Medusa server using a [subscriber](https://docs.medusajs.com/docs//learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that's executed when its associated event is emitted. In a subscriber, you can execute a workflow that performs actions in result of the event. + +In this step, you'll create a subscriber that listens to the `order.placed` event and executes the `handleOrderPointsWorkflow` workflow. + +Refer to the [Events and Subscribers](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md) documentation to learn more. + +Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, to create a subscriber, create the fle `src/subscribers/order-placed.ts` with the following content: + +```ts title="src/subscribers/order-placed.ts" +import type { + SubscriberArgs, + SubscriberConfig, +} from "@medusajs/framework" +import { handleOrderPointsWorkflow } from "../workflows/handle-order-points" + +export default async function orderPlacedHandler({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await handleOrderPointsWorkflow(container).run({ + input: { + order_id: data.id, + }, + }) +} + +export const config: SubscriberConfig = { + event: "order.placed", +} +``` + +The subscriber file must export: + +- An asynchronous subscriber function that's executed whenever the associated event, which is `order.placed` is triggered. +- A configuration object with an event property whose value is the event the subscriber is listening to. You can also pass an array of event names to listen to multiple events in the same subscriber. + +The subscriber function accepts an object with the following properties: + +- `event`: An object with the event's data payload. For example, the `order.placed` event has the order's ID in its data payload. +- `container`: The Medusa container, which you can use to resolve services and tools. + +In the subscriber function, you execute the `handleOrderPointsWorkflow` by invoking it, passing it the Medusa container, then using its `run` method, passing it the workflow's input. + +Whenever an order is placed now, the subscriber will be executed, which in turn will execute the workflow that handles the loyalty points flow. + +### Test it Out + +To test out the loyalty points flow, you'll use the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) that you installed in the first step. As mentioned in that step, the storefront will be installed in a separate directory from the Medusa application, and its name is `{project-name}-storefront`, where `{project-name}` is the name of your Medusa application's directory. + +So, run the following command in the Medusa application's directory to start the Medusa server: + +```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" +npm run dev +``` + +Then, run the following command in the Next.js Starter Storefront's directory to start the Next.js server: + +```bash npm2yarn badgeLabel="Storefront" badgeColor="blue" +npm run dev +``` + +The Next.js Starter Storefront will be running on `http://localhost:8000`, and the Medusa server will be running on `http://localhost:9000`. + +Open the Next.js Starter Storefront in your browser and create a new account by going to Account at the top right. + +Once you're logged in, add an item to the cart and go through the checkout flow. + +After you place the order, you'll see the following message in your Medusa application's terminal: + +```bash +info: Processing order.placed which has 1 subscribers +``` + +This message indicates that the `order.placed` event was emitted, and that your subscriber was executed. + +Since you didn't redeem any points during checkout, loyalty points will be added to your account. You'll implement an API route that allows you to retrieve the loyalty points in the next step. + +*** + +## Step 5: Retrieve Loyalty Points API Route + +Next, you want to allow customers to view their loyalty points. You can show them on their profile page, or during checkout. + +To expose a feature to clients, you create an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. + +You'll create an API route at the path `/store/customers/me/loyalty-points` that returns the loyalty points of the authenticated customer. + +Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). + +An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`. + +So, to create an API route at the path `/store/customers/me/loyalty-points`, create the file `src/api/store/customers/me/loyalty-points/route.ts` with the following content: + +```ts title="src/api/store/customers/me/loyalty-points/route.ts" + +import { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { LOYALTY_MODULE } from "../../../../../modules/loyalty" +import LoyaltyModuleService from "../../../../../modules/loyalty/service" + +export async function GET( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) { + const loyaltyModuleService: LoyaltyModuleService = req.scope.resolve( + LOYALTY_MODULE + ) + + const points = await loyaltyModuleService.getPoints( + req.auth_context.actor_id + ) + + res.json({ + points, + }) +} +``` + +Since you export a `GET` route handler function, you're exposing a `GET` endpoint at `/store/customers/me/loyalty-points`. The route handler function accepts two parameters: + +1. A request object with details and context on the request, such as body parameters or authenticated customer details. +2. A response object to manipulate and send the response. + +In the route handler, you resolve the Loyalty Module's service from the Medusa container (which is available at `req.scope`). + +Then, you call the service's `getPoints` method to retrieve the authenticated customer's loyalty points. Note that routes starting with `/store/customers/me` are only accessible by authenticated customers. You can access the authenticated customer ID from the request's context, which is available at `req.auth_context.actor_id`. + +Finally, you return the loyalty points in the response. + +You'll test out this route as you customize the Next.js Starter Storefront next. + +*** + +## Step 6: Show Loyalty Points During Checkout + +Now that you have the API route to retrieve the loyalty points, you can show them during checkout. + +In this step, you'll customize the Next.js Starter Storefront to show the loyalty points in the checkout page. + +First, you'll add a server action function that retrieves the loyalty points from the route you created earlier. In `src/lib/data/customer.ts`, add the following function: + +```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" +export const getLoyaltyPoints = async () => { + const headers = { + ...(await getAuthHeaders()), + } + + return sdk.client.fetch<{ points: number }>( + `/store/customers/me/loyalty-points`, + { + method: "GET", + headers, + } + ) + .then(({ points }) => points) + .catch(() => null) +} +``` + +You add a `getLoyaltyPoints` function that retrieves the authenticated customer's loyalty points from the API route you created earlier. You pass the authentication headers using the `getAuthHeaders` function, which is a utility function defined in the Next.js Starter Storefront. + +If the customer isn't authenticated, the request will fail. So, you catch the error and return `null` in that case. + +Next, you'll create a component that shows the loyalty points in the checkout page. Create the file `src/modules/checkout/components/loyalty-points/index.tsx` with the following content: + +```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={loyaltyPointsHighlights} +"use client" + +import { HttpTypes } from "@medusajs/types" +import { useEffect, useMemo, useState } from "react" +import { getLoyaltyPoints } from "../../../../lib/data/customer" +import { Button, Heading } from "@medusajs/ui" +import Link from "next/link" + +type LoyaltyPointsProps = { + cart: HttpTypes.StoreCart & { + promotions: HttpTypes.StorePromotion[] + } +} + +const LoyaltyPoints = ({ cart }: LoyaltyPointsProps) => { + const isLoyaltyPointsPromoApplied = useMemo(() => { + return cart.promotions.find( + (promo) => promo.id === cart.metadata?.loyalty_promo_id + ) !== undefined + }, [cart]) + const [loyaltyPoints, setLoyaltyPoints] = useState< + number | null + >(null) + + useEffect(() => { + getLoyaltyPoints() + .then((points) => { + console.log(points) + setLoyaltyPoints(points) + }) + }, []) + + const handleTogglePromotion = async ( + e: React.MouseEvent + ) => { + e.preventDefault() + // TODO apply or remove loyalty promotion + } + + return ( + <> +
+
+ + Loyalty Points + + {loyaltyPoints === null && ( + + Sign up to get and use loyalty points + + )} + {loyaltyPoints !== null && ( +
+ + + You have {loyaltyPoints} loyalty points + +
+ )} +
+ + ) +} + +export default LoyaltyPoints +``` + +You create a `LoyaltyPoints` component that accepts the cart's details as a prop. In the component, you: + +- Create a `isLoyaltyPointsPromoApplied` memoized value that checks whether the cart has a loyalty promotion applied. You use the `cart.metadata.loyalty_promo_id` property to check this. +- Create a `loyaltyPoints` state to store the customer's loyalty points. +- Call the `getLoyaltyPoints` function in a `useEffect` hook to retrieve the loyalty points from the API route you created earlier. You set the `loyaltyPoints` state with the retrieved points. +- Define `handleTogglePromotion` that, when clicked, would either apply or remove the promotion. You'll implement these functionalities later. +- Render the loyalty points in the component. If the customer isn't authenticated, you show a link to the account page to sign up. Otherwise, you show the loyalty points and a button to apply or remove the promotion. + +Next, you'll show this component at the end of the checkout's summary component. So, import the component in `src/modules/checkout/templates/checkout-summary/index.tsx`: + +```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" +import LoyaltyPoints from "../../components/loyalty-points" +``` + +Then, in the return statement of the `CheckoutSummary` component, add the following after the `div` wrapping the `DiscountCode`: + +```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" + +``` + +This will show the loyalty points component at the end of the checkout summary. + +### Test it Out + +To test out the customizations to the checkout flow, make sure both the Medusa application and Next.js Starter Storefront are running. + +Then, as an authenticated customer, add an item to cart and proceed to checkout. You'll find a new "Loyalty Points" section at the end of the checkout summary. + +![Loyalty Points Section at the end of the summary section at the right](https://res.cloudinary.com/dza7lstvk/image/upload/v1744195223/Medusa%20Resources/Screenshot_2025-04-09_at_1.39.34_PM_l5oltc.png) + +If you made a purchase before, you can see your loyalty points. You'll also see the "Apply Loyalty Points" button, which doesn't yet do anything. You'll add the functionality next. + +*** + +## Step 7: Apply Loyalty Points to Cart + +The next feature you'll implement allows the customer to apply their loyalty points during checkout. To implement the feature, you need: + +- A workflow that implements the steps of the apply loyalty points flow. +- An API route that exposes the workflow's functionality to clients. You'll then send a request to this API route to apply the loyalty points on the customer's cart. +- A function in the Next.js Starter Storefront that sends the request to the API route you created earlier. + +The workflow will have the following steps: + +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details. +- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. +- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. +- [getCartLoyaltyPromoAmountStep](#getCartLoyaltyPromoAmountStep): Get the amount to be discounted based on the loyalty points. +- [createPromotionsStep](https://docs.medusajs.com/references/medusa-workflows/steps/createPromotionsStep/index.html.md): Create a new loyalty promotion for the cart. +- [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/workflows/updateCartPromotionsWorkflow/index.html.md): Update the cart's promotions with the new loyalty promotion. +- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to store the ID of the loyalty promotion in the metadata. +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details again. + +Most of the workflow's steps are either provided by Medusa in the `@medusajs/medusa/core-flows` package or steps you've already implemented. You only need to implement the `getCartLoyaltyPromoAmountStep` step. + +### getCartLoyaltyPromoAmountStep + +The fourth step in the workflow is the `getCartLoyaltyPromoAmountStep`, which retrieves the amount to be discounted based on the loyalty points. This step is useful to determine how much discount to apply to the cart. + +To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo-amount.ts` with the following content: + +```ts title="src/workflows/steps/get-cart-loyalty-promo-amount.ts" highlights={getCartLoyaltyPromoAmountStepHighlights} +import { PromotionDTO, CustomerDTO } from "@medusajs/framework/types" +import { MedusaError } from "@medusajs/framework/utils" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import LoyaltyModuleService from "../../modules/loyalty/service" +import { LOYALTY_MODULE } from "../../modules/loyalty" + +export type GetCartLoyaltyPromoAmountStepInput = { + cart: { + id: string + customer: CustomerDTO + promotions?: PromotionDTO[] + total: number + } +} + +export const getCartLoyaltyPromoAmountStep = createStep( + "get-cart-loyalty-promo-amount", + async ({ cart }: GetCartLoyaltyPromoAmountStepInput, { container }) => { + // Check if customer has any loyalty points + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + const loyaltyPoints = await loyaltyModuleService.getPoints( + cart.customer.id + ) + + if (loyaltyPoints <= 0) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Customer has no loyalty points" + ) + } + + const pointsAmount = await loyaltyModuleService.calculatePointsFromAmount( + loyaltyPoints + ) + + const amount = Math.min(pointsAmount, cart.total) + + return new StepResponse(amount) + } +) +``` + +You create a step that accepts an object having the cart's details. + +In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `getPoints` method to retrieve the customer's loyalty points. If the customer has no loyalty points, you throw an error. + +Next, you call the `calculatePointsFromAmount` method to calculate the amount to be discounted based on the loyalty points. You use the `Math.min` function to ensure that the amount doesn't exceed the cart's total. + +Finally, you return a `StepResponse` with the amount to be discounted. + +### Create the Workflow + +You can now create the workflow that applies a loyalty promotion to the cart. + +To create the workflow, create the file `src/workflows/apply-loyalty-on-cart.ts` with the following content: + +```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={applyLoyaltyOnCartWorkflowHighlights} collapsibleLines="1-24" expandButtonLabel="Show Imports" +import { + createWorkflow, + transform, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" +import { + createPromotionsStep, + updateCartPromotionsWorkflow, + updateCartsStep, + useQueryGraphStep, +} from "@medusajs/medusa/core-flows" +import { + validateCustomerExistsStep, + ValidateCustomerExistsStepInput, +} from "./steps/validate-customer-exists" +import { + getCartLoyaltyPromoAmountStep, + GetCartLoyaltyPromoAmountStepInput, +} from "./steps/get-cart-loyalty-promo-amount" +import { CartData, CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE } from "../utils/promo" +import { CreatePromotionDTO } from "@medusajs/framework/types" +import { PromotionActions } from "@medusajs/framework/utils" +import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" + +type WorkflowInput = { + cart_id: string +} + +const fields = [ + "id", + "customer.*", + "promotions.*", + "promotions.application_method.*", + "promotions.rules.*", + "promotions.rules.values.*", + "currency_code", + "total", + "metadata", +] + +export const applyLoyaltyOnCartWorkflow = createWorkflow( + "apply-loyalty-on-cart", + (input: WorkflowInput) => { + // @ts-ignore + const { data: carts } = useQueryGraphStep({ + entity: "cart", + fields, + filters: { + id: input.cart_id, + }, + options: { + throwIfKeyNotFound: true, + }, + }) + + validateCustomerExistsStep({ + customer: carts[0].customer, + } as ValidateCustomerExistsStepInput) + + getCartLoyaltyPromoStep({ + cart: carts[0] as unknown as CartData, + throwErrorOn: "found", + }) + + const amount = getCartLoyaltyPromoAmountStep({ + cart: carts[0], + } as unknown as GetCartLoyaltyPromoAmountStepInput) + + // TODO create and apply the promotion on the cart + } +) +``` + +You create a workflow that accepts an object with the cart's ID as input. + +So far, you: + +- Use `useQueryGraphStep` to retrieve the cart's details.

Required: ${ + requiredPoints + }, Available: ${customerLoyaltyPoints}` + ) + } + } +) +``` + +Workflows have a special `hooks` property that includes all the hooks tht you can consume in that workflow. You consume the hook by invoking it from the workflow's `hooks` property. + +Since the hook is essentially a step function, it accepts the following parameters: + +- The hook's input passed from the workflow, which differs for each hook. The `validate` hook receives an object having the cart's details. +- The step context object, which contains the Medusa container. You can use it to resolve services and perform actions. + +In the hook, you resolve Query and the Loyalty Module's service. Then, you use Query to retrieve the cart's necessary details, including its promotions, customer, and metadata. + +After that, you retrieve the customer's loyalty points and calculate the required points to apply the loyalty promotion. + +If the customer doesn't have enough loyalty points, you throw an error. This will prevent the cart from being completed if the customer doesn't have enough loyalty points. + +*** + +## Test Out Cart Completion with Loyalty Points + +Since you now have the entire loyalty points flow implemented, you can test it out by going through the checkout flow, applying the loyalty points to the cart. + +When you place the order, if the customer has sufficient loyalty points, the validation hook will pass. + +Then, the `order.placed` event will be emitted, which will execute the subscriber that calls the `handleOrderPointsWorkflow`. + +In the workflow, since the order's cart has a loyalty promotion, the points equivalent to the promotion will be deducted, and the promotion becomes inactive. + +You can confirm that the loyalty points were deducted either by sending a request to the [retrieve loyalty points API route](#step-5-retrieve-loyalty-points-api-route), or by going through the checkout process again in the storefront. + +*** + +## Next Steps + +You've now implement a loyalty points system in Medusa.

A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. + +In this step, you'll create a custom module that provides the necessary functionalities to integrate Algolia with Medusa. + +Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. + +Before building the module, you need to install Algolia's JavaScript client. Run the following command in your Medusa application's root directory: + +```bash npm2yarn +npm install algoliasearch +``` + +### Create Module Directory + +A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/algolia`. + +### Create Service + +You define a module's functionalities in a service. A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, which is useful if your module defines tables in the database, or connect to a third-party service. + +In this section, you'll create the Algolia Module's service and the methods necessary to manage indexed products in Algolia and search through them. + +To create the Algolia Module's service, create the file `src/modules/algolia/service.ts` with the following content: + +```ts title="src/modules/algolia/service.ts" +import { algoliasearch, SearchClient } from "algoliasearch" + +type AlgoliaOptions = { + apiKey: string; + appId: string; + productIndexName: string; +} + +export type AlgoliaIndexType = "product" + +export default class AlgoliaModuleService { + private client: SearchClient + private options: AlgoliaOptions + + constructor({}, options: AlgoliaOptions) { + this.client = algoliasearch(options.appId, options.apiKey) + this.options = options + } + + // TODO add methods +} +``` + +You export a class that will be the Algolia Module's main service. In the service, you define two properties: + +- `client`: An instance of the Algolia Search Client, which you'll use to perform actions with Algolia's API. +- `options`: An object of options that the Module receives when it's registered, which you'll learn about later. The options contain: + - `apiKey`: The Algolia API key. + - `appId`: The Algolia App ID. + - `productIndexName`: The name of the index where products are stored. + +If you want to index other types of data, such as product categories, you can add new properties for their index names in the `AlgoliaOptions` type. + +A module's service receives the module's options as a second parameter in its constructor. In the constructor, you initialize the Algolia client using the module's options. + +A module has a container that holds all resources registered in that module, and you can access those resources in the first parameter of the constructor. Learn more about it in the [Module Container documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md). + +#### Index Data Method + +The first method you need to add to the servie is a method that receives an array of data to add or update in Algolia's index. + +Add the following methods to the `AlgoliaModuleService` class: + +```ts title="src/modules/algolia/service.ts" +export default class AlgoliaModuleService { + // ... + async getIndexName(type: AlgoliaIndexType) { + switch (type) { + case "product": + return this.options.productIndexName + default: + throw new Error(`Invalid index type: ${type}`) + } + } + + async indexData(data: Record[], type: AlgoliaIndexType = "product") { + const indexName = await this.getIndexName(type) + this.client.saveObjects({ + indexName, + objects: data.map((item) => ({ + ...item, + // set the object ID to allow updating later + objectID: item.id, + })), + }) + } +} +``` + +You define two methods: + +1. `getIndexName`: A method that receives an `AlgoliaIndexType` (defined in the previous snippt) and returns the index name for that type. In this case, you only have one type, `product`, so you return the product index name. + - If you want to index other types of data, you can add more cases to the switch statement. +2. `indexData`: A method that receives an array of data and an `AlgoliaIndexType`. The method indexes the data in the Algolia index for the given type. + - Notice that you set the `objectID` property of each object to the object's `id`. This ensures that you later update the object instead of creating a new one. + +#### Retrieve and Delete Methods + +The next methods you'll add to the service are methods to retrieve and delete data from the Algolia index. You'll see their use later as you keep the Algolia index in sync with Medusa. + +Add the following methods to the `AlgoliaModuleService` class: + +```ts title="src/modules/algolia/service.ts" +export default class AlgoliaModuleService { + // ... + + async retrieveFromIndex(objectIDs: string[], type: AlgoliaIndexType = "product") { + const indexName = await this.getIndexName(type) + return await this.client.getObjects>({ + requests: objectIDs.map((objectID) => ({ + indexName, + objectID, + })), + }) + } + + async deleteFromIndex(objectIDs: string[], type: AlgoliaIndexType = "product") { + const indexName = await this.getIndexName(type) + await this.client.deleteObjects({ + indexName, + objectIDs, + }) + } +} +``` + +You define two methods: + +1. `retrieveFromIndex`: A method that receives an array of object IDs and an `AlgoliaIndexType`. The method retrieves the objects with the given IDs from the Algolia index. +2. `deleteFromIndex`: A method that receives an array of object IDs and an `AlgoliaIndexType`. The method deletes the objects with the given IDs from the Algolia index. + +#### Search Method + +The last method you'll implement is a method to search through the Algolia index. You'll later use this method to expose the search functionality to clients, such as the Next.js Storefront. + +Add the following method to the `AlgoliaModuleService` class: + +```ts title="src/modules/algolia/service.ts" +export default class AlgoliaModuleService { + // ... + + async search(query: string, type: AlgoliaIndexType = "product") { + const indexName = await this.getIndexName(type) + return await this.client.search({ + requests: [ + { + indexName, + query, + }, + ], + }) + } +} +``` + +The `search` method receives a query string and an `AlgoliaIndexType`. The method searches through the Algolia index for the given type, such as products, and returns the results. + +### Export Module Definition + +The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. + +So, create the file `src/modules/algolia/index.ts` with the following content: + +```ts title="src/modules/algolia/index.ts" +import { Module } from "@medusajs/framework/utils" +import AlgoliaModuleService from "./service" + +export const ALGOLIA_MODULE = "algolia" + +export default Module(ALGOLIA_MODULE, { + service: AlgoliaModuleService, +}) +``` + +You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name, which is `algolia`. +2. An object with a required property `service` indicating the module's service. + +You also export the module's name as `ALGOLIA_MODULE` so you can reference it later. + +### Add Module to Medusa's Configurations + +Once you finish building the module, add it to Medusa's configurations to start using it. + +In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/algolia", + options: { + appId: process.env.ALGOLIA_APP_ID!, + apiKey: process.env.ALGOLIA_API_KEY!, + productIndexName: process.env.ALGOLIA_PRODUCT_INDEX_NAME!, + }, + }, + ], +}) +``` + +Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. + +You also pass an `options` property with the module's options, including the Algolia App ID, API Key, and the product index name. + +### Add Environment Variables + +Before you can start using the Algolia Module, you need to set the environment variables for the Algolia App ID, API Key, and the product index name. + +Add the following environment variables to your `.env` file: + +```env +ALGOLIA_APP_ID=your-algolia-app-id +ALGOLIA_API_KEY=your-algolia-api-key +ALGOLIA_PRODUCT_INDEX_NAME=your-product-index-name +``` + +Where: + +- `your-algolia-app-id` is your Algolia App ID. You can retrieve it from the Algolia dashboard by clicking at the application ID at the top left next to the sidebar. The pop up will show the application ID below the application's name. + +![Find the Algolia App ID by clicking on the application name in the Algolia dashboard, then copying the ID below the name in the pop-up](https://res.cloudinary.com/dza7lstvk/image/upload/v1742815360/Medusa%20Resources/Screenshot_2025-03-24_at_1.19.30_PM_kdp3y5.png) + +- `your-algolia-api-key` is your Algolia API Key. To retrieve it from the Algolia dashboard: + 1. Click on Settings in the sidebar. + 2. Choose API Keys under "Team and Access". + +![In the settings page, find the Team and Access section at the right of the page and choose API Keys](https://res.cloudinary.com/dza7lstvk/image/upload/v1742815534/Medusa%20Resources/Screenshot_2025-03-24_at_1.25.09_PM_hwsiba.png) + +3. Copy the Admin API Key. + +- `your-product-index-name` is the name of the index where you'll store products. You can find it by going to Search -> Index, and copying the index name at the top of the page. + +![In the Algolia dashboard, go to Search -> Index and copy the index name at the top of the page](https://res.cloudinary.com/dza7lstvk/image/upload/v1742815790/Medusa%20Resources/Screenshot_2025-03-24_at_1.28.58_PM_yq10sf.png) + +Your module is now ready for use. You'll see how to use it in the next steps. + +*** + +## Step 3: Sync Products to Algolia Workflow + +To keep the Algolia index in sync with Medusa, you need to trigger indexing when products are created, updated, or deleted in Medusa. You can also allow the admin to manually trigger a reindex. + +To implement the indexing functionality, you need to create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. + +Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). + +In this step, you'll create a workflow that indexes products in Algolia. In the next steps, you'll learn how to use the workflow when products are created, updated, or deleted, or when the admin manually triggers a reindex. + +The workflow has the following steps: + +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve products matching specified filters and pagination parameters. +- [syncProductsStep](#syncProductsStep): Index products in Algolia. + +Medusa provides the `useQueryGraphStep` in its `@medusajs/medusa/core-flows` package. So, you only need to implement the second step. + +### syncProductsStep + +In the second step of the workflow, you create or update indexes in Algolia for the products retrieved in the first step. + +To create the step, create the file `src/workflows/steps/sync-products.ts` with the following content: + +```ts title="src/workflows/steps/sync-products.ts" +import { ProductDTO } from "@medusajs/framework/types" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { ALGOLIA_MODULE } from "../../modules/algolia" +import AlgoliaModuleService from "../../modules/algolia/service" + +export type SyncProductsStepInput = { + products: ProductDTO[] +} + +export const syncProductsStep = createStep( + "sync-products", + async ({ products }: SyncProductsStepInput, { container }) => { + const algoliaModuleService: AlgoliaModuleService = container.resolve(ALGOLIA_MODULE) + + const existingProducts = (await algoliaModuleService.retrieveFromIndex( + products.map((product) => product.id), + "product" + )).results.filter(Boolean) + const newProducts = products.filter( + (product) => !existingProducts.some((p) => p.objectID === product.id) + ) + await algoliaModuleService.indexData( + products as unknown as Record[], + "product" + ) + + return new StepResponse(undefined, { + newProducts: newProducts.map((product) => product.id), + existingProducts, + }) + } + // TODO add compensation +) +``` + +You create a step with `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's unique name, which is `sync-products`. +2. An async function that receives two parameters: + - The step's input, which is in this case an object holding an array of products to sync into Algolia. + - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. + +In the step function, you resolve the Algolia Module's service from the Medusa container using the name you exported in the module definition's file. + +Then, you retrieve the products that are already indexed in Algolia and determine which products are new. You'll learn why this is useful in a bit. + +Finally, you pass the products you received in the input to Algolia to create or update its indices. + +A step function must return a `StepResponse` instance. The `StepResponse` constructor accepts two parameters: + +1. The step's output, which is the review created. +2. Data to pass to the step's compensation function. + +#### Compensation Function + +The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. + +To add a compensation function to a step, pass it as a third parameter to `createStep`: + +```ts title="src/workflows/steps/sync-products.ts" +export const syncProductsStep = createStep( + // ... + async (input, { container }) => { + if (!input) { + return + } + + const algoliaModuleService: AlgoliaModuleService = container.resolve(ALGOLIA_MODULE) + + if (input.newProducts) { + await algoliaModuleService.deleteFromIndex( + input.newProducts, + "product" + ) + } + + if (input.existingProducts) { + await algoliaModuleService.indexData( + input.existingProducts, + "product" + ) + } + } +) +``` + +The compensation function receives two parameters: + +1. The data you passed as a second parameter of `StepResponse` in the step function. +2. A context object similar to the step function that holds the Medusa container. + +In the compensation function, you resolve the Algolia Module's service from the container. Then, you delete from Algolia the products that were newly indexed, and revert the existing products to their original data. + +### Add Sync Products Workflow + +You can now create the worklow that syncs the products to Algolia. + +To create the workflow, create the file `src/workflows/sync-products.ts` with the following content: + +```ts title="src/workflows/sync-products.ts" +import { createWorkflow, WorkflowResponse } from "@medusajs/framework/workflows-sdk" +import { useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { syncProductsStep, SyncProductsStepInput } from "./steps/sync-products" + +type SyncProductsWorkflowInput = { + filters?: Record + limit?: number + offset?: number +} + +export const syncProductsWorkflow = createWorkflow( + "sync-products", + ({ filters, limit, offset }: SyncProductsWorkflowInput) => { + // @ts-ignore + const { data, metadata } = useQueryGraphStep({ + entity: "product", + fields: ["id", "title", "description", "handle", "thumbnail", "categories.*", "tags.*"], + pagination: { + take: limit, + skip: offset, + }, + filters: { + // @ts-ignore + status: "published", + ...filters, + }, + }) + + syncProductsStep({ + products: data, + } as SyncProductsStepInput) + + return new WorkflowResponse({ + products: data, + metadata, + }) + } +) +``` + +You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. + +It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is pagination and filter parameters for the products to retrieve. + +In the workflow's constructor function, you: + +1. Execute `useQueryGraphStep` to retrieve products from Medusa's database. This step uses Medusa's [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) tool to retrieve data across modules. You pass it the pagination and filter parameters you received in the input. +2. Execute `syncProductsStep` to index the products in Algolia. You pass it the products you retrieved in the previous step. + +A workflow must return an instance of `WorkflowResponse`. The `WorkflowResponse` constructor accepts the workflow's output as a parameter, which is an object holding the retrieved products and their pagination details. + +In the next step, you'll learn how to execute this workflow. + +*** + +## Step 4: Trigger Algolia Sync Manually + +As mentioned earlier, you'll trigger the Algolia sync automatically when product events occur, but you also want to allow the admin to manually trigger a reindex. + +In this step, you'll add the functionality to trigger the `syncProductsWorkflow` manually from the Medusa Admin dashboard. This requires: + +1. Creating a subscriber that listens to a custom `algolia.sync` event to trigger syncing products to Algolia. +2. Creating an API route that the Medusa Admin dashboard can call to emit the `algolia.sync` event, which triggers the subscriber. +3. Add a new page or UI route to the Medusa Admin dashboard to allow the admin to trigger the reindex. + +### Create Products Sync Subscriber + +A subscriber is an asynchronous function that listens to one or more events and performs actions when these events are emitted. A subscriber is useful when syncing data across systems, as the operation can be time-consuming and should be performed in the background. + +Learn more about subscribers in the [Events and Subscribers documentation](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). + +You create a subscriber in a TypeScript or JavaScript file under the `src/subscribers` directory. So, to create the subscriber that listens to the `algolia.sync` event, create the file `src/subscribers/products-sync.ts` with the following content: + +```ts title="src/subscribers/algolia-sync.ts" +import { + SubscriberArgs, + type SubscriberConfig, +} from "@medusajs/framework" +import { syncProductsWorkflow } from "../workflows/sync-products" + +export default async function algoliaSyncHandler({ + container, +}: SubscriberArgs) { + const logger = container.resolve("logger") + + let hasMore = true + let offset = 0 + const limit = 50 + let totalIndexed = 0 + + logger.info("Starting product indexing...") + + while (hasMore) { + const { result: { products, metadata } } = await syncProductsWorkflow(container) + .run({ + input: { + limit, + offset, + }, + }) + + hasMore = offset + limit < (metadata?.count ?? 0) + offset += limit + totalIndexed += products.length + } + + logger.info(`Successfully indexed ${totalIndexed} products`) +} + +export const config: SubscriberConfig = { + event: "algolia.sync", +} +``` + +A subscriber file must export: + +1. An asynchronous function, which is the subscriber that is executed when the event is emitted. +2. A configuration object that holds the name of the event the subscriber listens to, which is `algolia.sync` in this case. + +The subscriber function receives an object as a parameter that has a `container` property, which is the Medusa container. + +In the subscriber function, you initialize variables to keep track of the pagination and the total number of products indexed. + +Then, you start a loop that retrieves products in batches of 50 and indexes them in Algolia using the `syncProductsWorkflow`. Finally, you log the total number of products indexed. + +You'll learn how to emit the `algolia.sync` event next. + +If you want to sync other data types, you can do it in this subscriber as well. + +### Create API Route to Trigger Sync + +To allow the Medusa Admin dashboard to trigger the `algolia.sync` event, you need to create an API route that emits the event. + +An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. + +Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). + +An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`. + +So, to create an API route at the path `/admin/algolia/sync`, create the file `src/api/admin/algolia/sync/route.ts` with the following content: + +```ts title="src/api/admin/algolia/sync/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" +import { Modules } from "@medusajs/framework/utils" + +export async function POST( + req: MedusaRequest, + res: MedusaResponse +) { + const eventModuleService = req.scope.resolve(Modules.EVENT_BUS) + await eventModuleService.emit({ + name: "algolia.sync", + data: {}, + }) + res.send({ + message: "Syncing data to Algolia", + }) +} +``` + +Since you export a `POST` route handler function, you expose an `API` route at `/admin/algolia/sync`. The route handler function accepts two parameters: + +1. A request object with details and context on the request, such as body parameters or authenticated user details. +2. A response object to manipulate and send the response. + +In the route handler, you use the Medusa container that is available in the request object to resolve the [Event Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/event/index.html.md). This module manages events and their subscribers. + +Then, you emit the `algolia.sync` event using the Event Module's `emit` method, passing it the event name. + +Finally, you send a response with a message indicating that data is being synced to Algolia. + +### Add Algolia Sync Page to Admin Dashboard + +The last step is to add a new page to the admin dashboard that allows the admin to trigger the reindex. You add a new page using a [UI Route](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md). + +A UI route is a React component that specifies the content to be shown in a new page in the Medusa Admin dashboard. You'll create a UI route to display a button that triggers the reindex when clicked. + +Learn more about UI routes in the [UI Routes documentation](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md). + +#### Configure JS SDK + +Before creating the UI route, you'll configure Medusa's [JS SDK](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md) that you can use to send requests to the Medusa server from any client application, including your Medusa Admin customizations. + +The JS SDK is installed by default in your Medusa application. To configure it, create the file `src/admin/lib/sdk.ts` with the following content: + +```ts title="src/admin/lib/sdk.ts" +import Medusa from "@medusajs/js-sdk" + +export const sdk = new Medusa({ + baseUrl: "http://localhost:9000", + debug: process.env.NODE_ENV === "development", + auth: { + type: "session", + }, +}) +``` + +You create an instance of the JS SDK using the `Medusa` class from the JS SDK. You pass it an object having the following properties: + +- `baseUrl`: The base URL of the Medusa server. +- `debug`: A boolean indicating whether to log debug information into the console. +- `auth`: An object specifying the authentication type. When using the JS SDK for admin customizations, you use the `session` authentication type. + +#### Create UI Route + +You'll now create the UI route that displays a button to trigger the reindex. You create a UI route in a `page.tsx` file under a sub-directory of `src/admin/routes` directory. The file's path relative to `src/admin/routes` determines its path in the dashboard. + +So, to create a new page under the Settings section of the Medusa Admin, create the file `src/admin/routes/settings/algolia/page.tsx` with the following content: + +```tsx title="src/admin/routes/settings/algolia/page.tsx" +import { Container, Heading, Button, toast } from "@medusajs/ui" +import { useMutation } from "@tanstack/react-query" +import { sdk } from "../../../lib/sdk" +import { defineRouteConfig } from "@medusajs/admin-sdk" + +const AlgoliaPage = () => { + const { mutate, isPending } = useMutation({ + mutationFn: () => + sdk.client.fetch("/admin/algolia/sync", { + method: "POST", + }), + onSuccess: () => { + toast.success("Successfully triggered data sync to Algolia") + }, + onError: (err) => { + console.error(err) + toast.error("Failed to sync data to Algolia") + }, + }) + + const handleSync = () => { + mutate() + } + + return ( + +
+ Algolia Sync +
+
+ +
+ + ) +} + +export const config = defineRouteConfig({ + label: "Algolia", +}) + +export default AlgoliaPage +``` + +A UI route's file must export: + +1. A React component that defines the content of the page. +2. A configuration object that specifies the route's label in the dashboard. This label is used to show a sidebar item for the new route. + +In the React component, you use `useMutation` hook from `@tanstack/react-query` to create a mutation that sends a `POST` request to the API route you created earlier. In the mutation function, you use the JS SDK to send the request. + +Then, in the return statement, you display a button that triggers the mutation when clicked, which sends a request to the API route you created earlier. + +### Test it Out + +You'll now test out the entire flow, starting from triggering the reindex manually from the Medusa Admin dashboard, to checking the Algolia dashboard for the indexed products. + +Run the following command to start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, open the Medusa Admin at `http://localhost:9000/app` and log in with the credentials you set up in the first step. + +Can't remember the credentials? Learn how to create a user in the [Medusa CLI reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/medusa-cli/commands/user/index.html.md). + +After you log in, go to Settings from the sidebar. You'll find in the Settings' sidebar a new "Algolia" item. If you click on it, you'll find the page you created with the button to sync products to Algolia. + +If you click on the button, the products will be synced to Algolia. + +![The Algolia Sync page in the Medusa Admin dashboard with a button to sync products to Algolia](https://res.cloudinary.com/dza7lstvk/image/upload/v1742820813/Medusa%20Resources/Screenshot_2025-03-24_at_2.52.31_PM_eiegzb.png) + +You can check that the sync ran and was completed by checking the Medusa logs in the terminal where you started the Medusa application. You should find the following messages: + +```bash +info: Processing algolia.sync which has 1 subscribers +info: Starting product indexing... +info: Successfully indexed 4 products +``` + +These messages indicate that the `algolia.sync` event was emitted, which triggered the subscriber you created to sync the products using the `syncProductsWorkflow`. + +Finally, you can check the Algolia dashboard to see the indexed products. Go to Search -> Index, and check the records of the index you set up in the Algolia Module's options (`products`, for example). + +![The Algolia dashboard showing the indexed products](https://res.cloudinary.com/dza7lstvk/image/upload/v1742821034/Medusa%20Resources/Screenshot_2025-03-24_at_2.56.38_PM_mtojrv.png) + +*** + +## Step 5: Update Index on Product Changes + +You'll now automate the indexing of the products whenever a change occurs. That includes when a product is created, updated, or deleted. + +Similar to before, you'll create subscribers to listen to these events. + +### Handle Create and Update Products + +The action to perform when a product is created or updated is the same. You'll use the `syncProductsWorkflow` to sync the product to Algolia. + +So, you only need one subscriber to handle these two events. To create the subscriber, create the file `src/subscribers/product-sync.ts` with the following content: + +```ts title="src/subscribers/product-sync.ts" +import { SubscriberArgs, type SubscriberConfig } from "@medusajs/framework" +import { syncProductsWorkflow } from "../workflows/sync-products" + +export default async function handleProductEvents({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await syncProductsWorkflow(container) + .run({ + input: { + filters: { + id: data.id, + }, + }, + }) +} + +export const config: SubscriberConfig = { + event: ["product.created", "product.updated"], +} +``` + +The subscriber listens to the `product.created` and `product.updated` events. When either of these events is emitted, the subscriber triggers the `syncProductsWorkflow` to sync the product to Algolia. + +When the `product.created` and `product.updated` events are emitted, the product's ID is passed in the event data payload, which you can access in the `event.data` property of the subscriber function's parameter. + +So, you pass the product's ID to the `syncProductsWorkflow` as a filter to retrieve only the product that was created or updated. + +#### Test it Out + +To test it out, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, either create a product or update an existing one using the Medusa Admin dashboard. If you check the Algolia dashboard, you'll find that the product was created or updated. + +### Handle Product Deletion + +When a product is deleted, you need to remove it from the Algolia index. As this requires a different action than creating or updating a product, you'll create a new workflow that deletes the product from Algolia, then create a subscriber that listens to the `product.deleted` event to trigger the workflow. + +#### Create Delete Product Step + +The workflow to delete a product from Algolia will have only one step that deletes products by their IDs from Algolia. + +So, create the step at `src/workflows/steps/delete-products-from-algolia.ts` with the following content: + +```ts title="src/workflows/steps/delete-products-from-algolia.ts" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { ALGOLIA_MODULE } from "../../modules/algolia" + +export type DeleteProductsFromAlgoliaWorkflow = { + ids: string[] +} + +export const deleteProductsFromAlgoliaStep = createStep( + "delete-products-from-algolia-step", + async ( + { ids }: DeleteProductsFromAlgoliaWorkflow, + { container } + ) => { + const algoliaModuleService = container.resolve(ALGOLIA_MODULE) + + const existingRecords = await algoliaModuleService.retrieveFromIndex( + ids, + "product" + ) + await algoliaModuleService.deleteFromIndex( + ids, + "product" + ) + + return new StepResponse(undefined, existingRecords) + }, + async (existingRecords, { container }) => { + if (!existingRecords) { + return + } + const algoliaModuleService = container.resolve(ALGOLIA_MODULE) + + await algoliaModuleService.indexData( + existingRecords as unknown as Record[], + "product" + ) + } +) +``` + +The step receives the IDs of the products to delete as an input. + +In the step, you resolve the Algolia Module's service and retrieve the existing records from Algolia. This is useful to revert the deletion if an error occurs. + +Then, you delete the products from Algolia and pass the existing records to the compensation function. + +In the compensation function, you reindex the existing records if an error occurs. + +#### Create Delete Product Workflow + +You can now create the workflow that deletes products from Algolia. Create the file `src/workflows/delete-products-from-algolia.ts` with the following content: + +```ts title="src/workflows/delete-products-from-algolia.ts" +import { createWorkflow } from "@medusajs/framework/workflows-sdk" +import { deleteProductsFromAlgoliaStep } from "./steps/delete-products-from-algolia" + +type DeleteProductsFromAlgoliaWorkflowInput = { + ids: string[] +} + +export const deleteProductsFromAlgoliaWorkflow = createWorkflow( + "delete-products-from-algolia", + (input: DeleteProductsFromAlgoliaWorkflowInput) => { + deleteProductsFromAlgoliaStep(input) + } +) +``` + +The workflow receives an object with the IDs of the products to delete. It then executes the `deleteProductsFromAlgoliaStep` to delete the products from Algolia. + +#### Create Delete Product Subscriber + +Finally, you'll create the subscriber that listens to the `product.deleted` event to trigger the above workflow. + +Create the file `src/subscribers/product-delete.ts` with the following content: + +```ts title="src/subscribers/product-delete.ts" +import { SubscriberArgs, type SubscriberConfig } from "@medusajs/framework" +import { deleteProductsFromAlgoliaWorkflow } from "../workflows/delete-products-from-algolia" + +export default async function handleProductDeleted({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await deleteProductsFromAlgoliaWorkflow(container) + .run({ + input: { + ids: [data.id], + }, + }) +} + +export const config: SubscriberConfig = { + event: "product.deleted", +} +``` + +The subscriber listens to the `product.deleted` event. When the event is emitted, the subscriber triggers the `deleteProductsFromAlgoliaWorkflow`, passing it the ID of the product to delete. + +#### Test it Out + +To test product deletion, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, delete a product from the Medusa Admin dashboard. If you check the Algolia dashboard, you'll find that the product was deleted there as well. + +*** + +## Step 6: Add Search API Route + +Before customizing the storefront to show the search UI, you'll create an API route in your Medusa application that allows storefronts to search products in Algolia. + +While you can implement the search functionality directly in the storefront to interact with Algolia, this approach centralizes your search integration in Medusa, allowing you to change or modify the integration as necessary. You can also rely on the same behavior and results across different storefronts. + +To implement the API Route, create the file `src/api/store/products/search/route.ts` with the following content: + +```ts title="src/api/store/products/search/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" +import { ALGOLIA_MODULE } from "../../../../modules/algolia" +import AlgoliaModuleService from "../../../../modules/algolia/service" +import { z } from "zod" + +export const SearchSchema = z.object({ + query: z.string(), +}) + +type SearchRequest = z.infer + +export async function POST( + req: MedusaRequest, + res: MedusaResponse +) { + const algoliaModuleService: AlgoliaModuleService = req.scope.resolve(ALGOLIA_MODULE) + + const { query } = req.validatedBody + + const results = await algoliaModuleService.search( + query as string + ) + + res.json(results) +} +``` + +You first define a schema with [Zod](https://zod.dev/), a library to define validation schemas. The schema defines the structure of the request body, which in this case is an object with a `query` property of type `string`. Later, you'll use the schema to enforce request body validation. + +Then, you expose a `POST` API Route at `/store/search` that searches Algolia using the `search` method you implemented in the Algolia Module's service. You pass to it the query string from the request body. + +Finally, you return the search results as it is in the response. + +### Add Validation Middleware + +To ensure that requests sent to the API route have the required request body parameters, you can use a [middleware](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). A middleware is a function executed when a request is sent to an API Route. It's executed before the route handler. + +Learn more about middleware in the [Middlewares documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). + +Middlewares are created in the `src/api/middlewares.ts` file. So create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformBody, +} from "@medusajs/framework/http" +import { SearchSchema } from "./store/products/search/route" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/products/search", + method: ["POST"], + middlewares: [ + validateAndTransformBody(SearchSchema), + ], + }, + ], +}) +``` + +To export the middlewares, you use the `defineMiddlewares` function. It accepts an object having a `routes` property, whose value is an array of middleware route objects. Each middleware route object has the following properties: + +- `matcher`: The path of the route the middleware applies to. +- `method`: The HTTP methods the middleware applies to, which is in this case `POST`. +- `middlewares`: An array of middleware functions to apply to the route. You apply the `validateAndTransformBody` middleware which ensures that a request's body has the required parameters. You pass it the schema you defined earlier in the API route's file. + +You can use the search API route now. You'll see it in action as you customize the storefront in the next step. + +*** + +## Step 7: Search Products in Next.js Storefront + +The last step is to provide the search functionalities to customers on your storefront. In the first step, you installed the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) along with the Medusa application. + +In this step, you'll customize the Next.js Starter Storefront to add the search functionality. + +The Next.js Starter Storefront was installed in a separate directory from Medusa. The directory's name is `{your-project}-storefront`. + +So, if your Medusa application's directory is `medusa-search`, you can find the storefront by going back to the parent directory and changing to the `medusa-search-storefront` directory: + +```bash +cd ../medusa-search-storefront # change based on your project name +``` + +### Install Algolia Packages + +Before adding the implementation of the search functionality, you need to install the Algolia packages necessary to add the search functionality in your storefront. + +Run the following command in the directory of your Next.js Starter Storefront: + +```bash npm2yarn +npm install algoliasearch react-instantsearch +``` + +This installs the Algolia Search JavaScript client and the React InstantSearch library, which you'll use to build the search functionality. + +### Add Search Client Configuration + +Next, you need to configure the search client. Not only do you need to initialize Algolia, but you also need to change the searching mechanism to use your custom API route in the Medusa application instead of Algolia's API directly. + +In `src/lib/config.ts`, add the following imports at the top of the file: + +```ts title="src/lib/config.ts" badgeLabel="Storefront" badgeColor="blue" +import { + liteClient as algoliasearch, + LiteClient as SearchClient, +} from "algoliasearch/lite" +``` + +Then, add the following at the end of the file: + +```ts title="src/lib/config.ts" badgeLabel="Storefront" badgeColor="blue" +export const searchClient: SearchClient = { + ...(algoliasearch( + process.env.NEXT_PUBLIC_ALGOLIA_APP_ID || "", + process.env.NEXT_PUBLIC_ALGOLIA_API_KEY || "" + )), + search: async (params) => { + const request = Array.isArray(params) ? params[0] : params + const query = "params" in request ? request.params?.query : + "query" in request ? request.query : "" + + if (!query) { + return { + results: [ + { + hits: [], + nbHits: 0, + nbPages: 0, + page: 0, + hitsPerPage: 0, + processingTimeMS: 0, + query: "", + params: "", + }, + ], + } + } + + return await sdk.client.fetch(`/store/products/search`, { + method: "POST", + body: { + query, + }, + }) + }, +} +``` + +In the code above, you create a `searchClient` object that initializes the Algolia client with your Algolia App ID and API Key. + +You also define a `search` method that sends a `POST` request to the search API route you created in the Medusa application. You use the JS SDK (which is initialized in this same file) to send the request. + +### Set Environment Variables + +In the storefront's `.env.local` file, add the following Algolia-related environment variables: + +```plain badgeLabel="Storefront" badgeColor="blue" +NEXT_PUBLIC_ALGOLIA_APP_ID=your_algolia_app_id +NEXT_PUBLIC_ALGOLIA_API_KEY=your_algolia_api_key +NEXT_PUBLIC_ALGOLIA_PRODUCT_INDEX_NAME=your-products-index-name +``` + +Where: + +- `your_algolia_app_id` is your Algolia App ID, as explained in the [Add Environment Variables section](#add-environment-variables) earlier. +- `your_algolia_api_key` is your Algolia Search API key. You can retrieve it from the [same API keys page on the Algolia dashboard](#add-environment-variables) that you retrieved the Admin API key from. +- `your-products-index-name` is the name of the index you created in Algolia to store the products, which you can retrieve as explained in the [Add Environment Variables section](#add-environment-variables) earlier. You'll use this variable later. + +Do not expose your Admin API key in the storefront. The Admin API key should only be used in the Medusa application to interact with Algolia, as it has full access to your Algolia account. + +### Add Search Modal Component + +You'll now add a search modal component that customers can use to search for products. The search modal will display the search results in real-time as the customer types in the search query. + +Later, you'll add the search modal to the navigation bar, allowing customers to open the search modal from any page. + +Create the file `src/modules/search/components/modal/index.tsx` with the following content: + +```tsx title="src/modules/search/components/modal/index.tsx" badgeLabel="Storefront" badgeColor="blue" +"use client" + +import React, { useEffect, useState } from "react" +import { Hits, InstantSearch, SearchBox } from "react-instantsearch" +import { searchClient } from "../../../../lib/config" +import Modal from "../../../common/components/modal" +import { Button } from "@medusajs/ui" +import Image from "next/image" +import Link from "next/link" +import { usePathname } from "next/navigation" + +type Hit = { + objectID: string; + id: string; + title: string; + description: string; + handle: string; + thumbnail: string; +} + +export default function SearchModal() { + const [isOpen, setIsOpen] = useState(false) + const pathname = usePathname() + + useEffect(() => { + setIsOpen(false) + }, [pathname]) + + return ( + <> +
+ +
+ setIsOpen(false)}> + + + + + + + ) +} + +const Hit = ({ hit }: { hit: Hit }) => { + return ( +
+ {hit.title} +
+

{hit.title}

+

{hit.description}

+
+ +
+ ) +} +``` + +You create a `SearchModal` component that displays a search box and the search results using widgets from Algolia's `react-instantsearch` library. + +To display each result item (or hit), you create a `Hit` component that displays the product's title, description, and thumbnail. You also add a link to the product's page. + +Finally, you show the search modal when the customer clicks a "Search" button, which you'll add to the navigation bar next. + +### Add Search Button to Navigation Bar + +The last step is to show the search button in the navigation bar. + +In `src/modules/layout/templates/nav/index.tsx`, add the following imports at the top of the file: + +```tsx title="src/modules/layout/templates/nav/index.tsx" badgeLabel="Storefront" badgeColor="blue" +import SearchModal from "@modules/search/components/modal" +``` + +Then, in the return statement of the `Nav` component, add the `SearchModal` component before the `div` surrounding the "Account" link: + +```tsx title="src/modules/layout/templates/nav/index.tsx" badgeLabel="Storefront" badgeColor="blue" + +``` + +The search button will now appear in the navigation bar before the Account link. + +### Test it Out + +To test out the storefront changes and the search API route, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +Then, start the Next.js Starter Storefront from its directory: + +```bash npm2yarn +npm run dev +``` + +Next, go to `localhost:8000`. You'll find a Search button at the top right of the navigation bar. If you click on it, you can search through your products. You can also click on a product to view its page. + +![The Next.js Starter Storefront showing the search modal with search results](https://res.cloudinary.com/dza7lstvk/image/upload/v1742827777/Medusa%20Resources/Screenshot_2025-03-24_at_4.49.23_PM_kzhldx.png) + +*** + +## Next Steps + +You've now integrated Algolia with Medusa and added search functionality to your storefront.

The options contain: - - `apiKey`: The Algolia API key. - - `appId`: The Algolia App ID. - - `productIndexName`: The name of the index where products are stored. +The service must have an `identifier` static property, which is a unique identifier for the provider. You set the identifier to `shipstation`. -If you want to index other types of data, such as product categories, you can add new properties for their index names in the `AlgoliaOptions` type. +A module can receive options that are set when you later add the module to Medusa's configurations.

So, add to the class defined in `src/modules/shipstation/client.ts` a new method: + +```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights2} +// other imports... +import { + CarriersResponse, +} from "./types" + +export class ShipStationClient { // ... - async getIndexName(type: AlgoliaIndexType) { - switch (type) { - case "product": - return this.options.productIndexName - default: - throw new Error(`Invalid index type: ${type}`) + async getCarriers(): Promise { + return await this.sendRequest("/carriers") + } +} +``` + +You added a new `getCarriers` method that uses the `sendRequest` method to send a request to the [ShipStation's List Carriers endpoint](https://docs.shipstation.com/openapi/carriers/list_carriers). The method returns `CarriersResponse` that you defined earlier. + +Finally, add the `getFulfillmentOptions` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights3} +// other imports... +import { + FulfillmentOption, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async getFulfillmentOptions(): Promise { + const { carriers } = await this.client.getCarriers() + const fulfillmentOptions: FulfillmentOption[] = [] + + carriers + .filter((carrier) => !carrier.disabled_by_billing_plan) + .forEach((carrier) => { + carrier.services.forEach((service) => { + fulfillmentOptions.push({ + id: `${carrier.carrier_id}__${service.service_code}`, + name: service.name, + carrier_id: carrier.carrier_id, + carrier_service_code: service.service_code, + }) + }) + }) + + return fulfillmentOptions + } +} +``` + +In the `getFulfillmentOptions` method, you retrieve the carriers from ShipStation. You then filter out the carriers disabled by your ShipStation billing plan, and loop over the remaining carriers and their services. + +You return an array of fulfillment-option objects, where each object represents a carrier and service pairing. Each object has the following properties: + +- an `id` property, which you set to a combination of the carrier ID and the service code. +- a `name` property, which you set to the service's `name`. The admin user will see this name when they create a shipping option for the ShipStation provider. +- You can pass other data, such as `carrier_id` and `carrier_service_code`, and Medusa will store the fulfillment option in the `data` property of shipping options created later. + +Learn more about the shipping option's `data` property in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). + +You'll see this method in action later when you create a shipping option. + +#### canCalculate + +When an admin user creates a shipping option for your provider, they can choose whether the price is flat rate or calculated during checkout. + +If the user chooses calculated, Medusa validates that your fulfillment provider supports calculated prices using the `canCalculate` method of your provider's service. + +This method accepts the shipping option's `data` field, which will hold the data of an option returned by `getFulfillmentOptions`. It returns a boolean value indicating whether the shipping option can have a calculated price. + +Add the method to `ShipStationProviderService` in `src/modules/shipstation/service.ts`: + +```ts title="src/modules/shipstation/service.ts" +// other imports... +import { + // ... + CreateShippingOptionDTO, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async canCalculate(data: CreateShippingOptionDTO): Promise { + return true + } +} +``` + +Since all shipping option prices can be calculated with ShipStation based on the chosen carrier and service zone, you always return `true` in this method. + +You'll implement the calculation mechanism in a later method. + +#### calculatePrice + +When the customer views available shipping options during checkout, the Medusa application requests the calculated price from your fulfillment provider using its `calculatePrice` method. + +To retrieve shipping prices with ShipStation, you create a shipment first then get its rates. So, in the `calculatePrice` method, you'll either: + +- Send a request to [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates) that creates a shipment and returns its prices; +- Or, if a shipment was already created before, you'll retrieve its prices using [ShipStation's get shipment rates endpoint](https://docs.shipstation.com/openapi/shipments/list_shipment_rates). + +First, add the following types to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" highlights={typesHighlights1} +export type ShipStationAddress = { + name: string + phone: string + email?: string | null + company_name?: string | null + address_line1: string + address_line2?: string | null + address_line3?: string | null + city_locality: string + state_province: string + postal_code: string + country_code: string + address_residential_indicator: "unknown" | "yes" | "no" + instructions?: string | null + geolocation?: { + type?: string + value?: string + }[] +} + +export type Rate = { + rate_id: string + shipping_amount: { + currency: string + amount: number + } + insurance_amount: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + other_amount: { + currency: string + amount: number + } + tax_amount: { + currency: string + amount: number + } +} + +export type RateResponse = { + rates: Rate[] +} + +export type GetShippingRatesRequest = { + shipment_id?: string + shipment?: Omit + rate_options: { + carrier_ids: string[] + service_codes: string[] + preferred_currency: string + } +} + +export type GetShippingRatesResponse = { + shipment_id: string + carrier_id?: string + service_code?: string + external_order_id?: string + rate_response: RateResponse +} + +export type Shipment = { + shipment_id: string + carrier_id: string + service_code: string + ship_to: ShipStationAddress + return_to?: ShipStationAddress + is_return?: boolean + ship_from: ShipStationAddress + items?: [ + { + name?: string + quantity?: number + sku?: string } - } - - async indexData(data: Record[], type: AlgoliaIndexType = "product") { - const indexName = await this.getIndexName(type) - this.client.saveObjects({ - indexName, - objects: data.map((item) => ({ - ...item, - // set the object ID to allow updating later - objectID: item.id, - })), - }) - } + ] + warehouse_id?: string + shipment_status: "pending" | "processing" | "label_purchased" | "cancelled" + [k: string]: unknown } + ``` -You define two methods: +You add the following types: -1. `getIndexName`: A method that receives an `AlgoliaIndexType` (defined in the previous snippt) and returns the index name for that type. In this case, you only have one type, `product`, so you return the product index name. - - If you want to index other types of data, you can add more cases to the switch statement. -2. `indexData`: A method that receives an array of data and an `AlgoliaIndexType`. The method indexes the data in the Algolia index for the given type. - - Notice that you set the `objectID` property of each object to the object's `id`. This ensures that you later update the object instead of creating a new one. +- `ShipStationAddress`: an address to ship from or to. +- `Rate`: a price rate for a specified carrier and service zone. +- `RateResponse`: The response when retrieving rates. +- `GetShippingRatesRequest`: The request body data for [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates). You can refer to their API reference for other accepted parameters. +- `GetShippingRatesResponse`: The response of the [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates). You can refer to their API reference for other response fields. +- `Shipment`: A shipment's details. -#### Retrieve and Delete Methods +Then, add the following methods to `ShipStationClient`: -The next methods you'll add to the service are methods to retrieve and delete data from the Algolia index. You'll see their use later as you keep the Algolia index in sync with Medusa. - -Add the following methods to the `AlgoliaModuleService` class: - -```ts title="src/modules/algolia/service.ts" -export default class AlgoliaModuleService { +```ts title="src/modules/shipstation/client.ts" highlights={serviceHighlights7} +// other imports... +import { // ... + GetShippingRatesRequest, + GetShippingRatesResponse, + RateResponse, +} from "./types" - async retrieveFromIndex(objectIDs: string[], type: AlgoliaIndexType = "product") { - const indexName = await this.getIndexName(type) - return await this.client.getObjects>({ - requests: objectIDs.map((objectID) => ({ - indexName, - objectID, - })), - }) - } - - async deleteFromIndex(objectIDs: string[], type: AlgoliaIndexType = "product") { - const indexName = await this.getIndexName(type) - await this.client.deleteObjects({ - indexName, - objectIDs, - }) - } -} -``` - -You define two methods: - -1. `retrieveFromIndex`: A method that receives an array of object IDs and an `AlgoliaIndexType`. The method retrieves the objects with the given IDs from the Algolia index. -2. `deleteFromIndex`: A method that receives an array of object IDs and an `AlgoliaIndexType`. The method deletes the objects with the given IDs from the Algolia index. - -#### Search Method - -The last method you'll implement is a method to search through the Algolia index. You'll later use this method to expose the search functionality to clients, such as the Next.js Storefront. - -Add the following method to the `AlgoliaModuleService` class: - -```ts title="src/modules/algolia/service.ts" -export default class AlgoliaModuleService { +export class ShipStationClient { // ... + async getShippingRates( + data: GetShippingRatesRequest + ): Promise { + return await this.sendRequest("/rates", { + method: "POST", + body: JSON.stringify(data), + }).then((resp) => { + if (resp.rate_response.errors?.length) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `An error occured while retrieving rates from ShipStation: ${ + resp.rate_response.errors.map((error) => error.message) + }` + ) + } - async search(query: string, type: AlgoliaIndexType = "product") { - const indexName = await this.getIndexName(type) - return await this.client.search({ - requests: [ - { - indexName, - query, - }, - ], + return resp }) } + + async getShipmentRates(id: string): Promise { + return await this.sendRequest(`/shipments/${id}/rates`) + } } ``` -The `search` method receives a query string and an `AlgoliaIndexType`. The method searches through the Algolia index for the given type, such as products, and returns the results. +The `getShippingRates` method accepts as a parameter the data to create a shipment and retrieve its rate. In the method, you send the request using the `sendRequest` method, and throw any errors in the rate retrieval before returning the response. -### Export Module Definition +The `getShipmentRates` method accepts the ID of the shipment as a parameter, sends the request using the `sendRequest` method and returns its response holding the shipment's rates. -The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. +Next, add to `ShipStationProviderService` a private method that'll be used to create a shipment in ShipStation and get its rates: -So, create the file `src/modules/algolia/index.ts` with the following content: +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights8} +// other imports... +import { + // ... + MedusaError, +} from "@medusajs/framework/utils" +import { + // ... + CalculateShippingOptionPriceDTO, +} from "@medusajs/framework/types" +import { + GetShippingRatesResponse, + ShipStationAddress, +} from "./types" -```ts title="src/modules/algolia/index.ts" -import { Module } from "@medusajs/framework/utils" -import AlgoliaModuleService from "./service" +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + private async createShipment({ + carrier_id, + carrier_service_code, + from_address, + to_address, + items, + currency_code, + }: { + carrier_id: string + carrier_service_code: string + from_address?: { + name?: string + address?: Omit< + StockLocationAddressDTO, "created_at" | "updated_at" | "deleted_at" + > + }, + to_address?: Omit< + CartAddressDTO, "created_at" | "updated_at" | "deleted_at" | "id" + >, + items: CartLineItemDTO[] | OrderLineItemDTO[], + currency_code: string + }): Promise { + if (!from_address?.address) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "from_location.address is required to calculate shipping rate" + ) + } + const ship_from: ShipStationAddress = { + name: from_address?.name || "", + phone: from_address?.address?.phone || "", + address_line1: from_address?.address?.address_1 || "", + city_locality: from_address?.address?.city || "", + state_province: from_address?.address?.province || "", + postal_code: from_address?.address?.postal_code || "", + country_code: from_address?.address?.country_code || "", + address_residential_indicator: "unknown", + } + if (!to_address) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "shipping_address is required to calculate shipping rate" + ) + } + + const ship_to: ShipStationAddress = { + name: `${to_address.first_name} ${to_address.last_name}`, + phone: to_address.phone || "", + address_line1: to_address.address_1 || "", + city_locality: to_address.city || "", + state_province: to_address.province || "", + postal_code: to_address.postal_code || "", + country_code: to_address.country_code || "", + address_residential_indicator: "unknown", + } -export const ALGOLIA_MODULE = "algolia" + // TODO create shipment + } +} +``` -export default Module(ALGOLIA_MODULE, { - service: AlgoliaModuleService, +The `createShipment` method accepts as a parameter an object having the following properties: + +- `carrier_id`: The ID of the carrier to create the shipment for. +- `carrier_service_code`: The code of the carrier's service. +- `from_address`: The address to ship items from, which is the address of the stock location associated with a shipping option. +- `to_address`: The address to ship items to, which is the customer's address. +- `items`: An array of the items in the cart or order (for fulfilling the order later). +- `currency_code`: The currency code of the cart or order. + +In the `createShipment` method, so far you only prepare the data to be sent to ShipStation.

You can instead pass a package for each item, specifying its weight and optionally its height, width, and length. -You also export the module's name as `ALGOLIA_MODULE` so you can reference it later. +Finally, add the `calculatePrice` method to `ShipStationProviderService`: -### Add Module to Medusa's Configurations +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights5} +// other imports... +import { + // ... + CalculatedShippingOptionPrice, +} from "@medusajs/framework/types" -Once you finish building the module, add it to Medusa's configurations to start using it. +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async calculatePrice( + optionData: CalculateShippingOptionPriceDTO["optionData"], + data: CalculateShippingOptionPriceDTO["data"], + context: CalculateShippingOptionPriceDTO["context"] + ): Promise { + const { shipment_id } = data as { + shipment_id?: string + } || {} + const { carrier_id, carrier_service_code } = optionData as { + carrier_id: string + carrier_service_code: string + } + let rate: Rate | undefined -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + if (!shipment_id) { + const shipment = await this.createShipment({ + carrier_id, + carrier_service_code, + from_address: { + name: context.from_location?.name, + address: context.from_location?.address, + }, + to_address: context.shipping_address, + items: context.items || [], + currency_code: context.currency_code as string, + }) + rate = shipment.rate_response.rates[0] + } else { + const rateResponse = await this.client.getShipmentRates(shipment_id) + rate = rateResponse[0].rates[0] + } + + const calculatedPrice = !rate ? 0 : rate.shipping_amount.amount + rate.insurance_amount.amount + + rate.confirmation_amount.amount + rate.other_amount.amount + + (rate.tax_amount?.amount || 0) + + return { + calculated_amount: calculatedPrice, + is_calculated_price_tax_inclusive: !!rate?.tax_amount, + } + } +} +``` + +The `calculatePrice` method accepts the following parameters: + +1. The `data` property of the chosen shipping option during checkout. +2. The `data` property of the shipping method, which will hold the ID of the shipment in ShipStation. +3. An object of the checkout's context, including the cart's items, the location associated with the shipping option, and more. + +In the method, you first check if a `shipment_id` is already stored in the shipping method's `data` property. If so, you retrieve the shipment's rates using the client's `getShipmentRates` method. Otherwise, you use the `createShipment` method to create the shipment and get its rates. + +A rate returned by ShipStation has four properties that, when added up, make up the full price: `shipping_amount`, `insurance_amount`, `confirmation_amount`, and `other_amount`. It may have a `tax_amount` property, which is the amount for applied taxes. + +Learn more about these fields in [ShipStation's documentation](https://docs.shipstation.com/rate-shopping#about-the-response). + +The method returns an object having the following properties: + +- `calculated_amount`: The shipping method's price calculated by adding the four rate properties with the tax property, if available. +- `is_calculated_price_tax_inclusive`: Whether the price includes taxes, which is inferred from whether the `tax_amount` property is set in the rate. + +Customers will now see the calculated price of a ShipStation shipping option during checkout. + +#### validateFulfillmentData + +When a customer chooses a shipping option during checkout, Medusa creates a shipping method from that option. A shipping method has a `data` property to store data relevant for later processing of the method and its fulfillments. + +So, in the `validateFulfillmentData` method of your provider, you'll create a shipment in ShipStation if it wasn't already created using their [get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates), and store the ID of that shipment in the created shipping method's `data` property. + +Add the `validateFulfillmentData` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights4} +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async validateFulfillmentData( + optionData: Record, + data: Record, + context: Record + ): Promise { + let { shipment_id } = data as { + shipment_id?: string + } + + if (!shipment_id) { + const { carrier_id, carrier_service_code } = optionData as { + carrier_id: string + carrier_service_code: string + } + const shipment = await this.createShipment({ + carrier_id, + carrier_service_code, + from_address: { + // @ts-ignore + name: context.from_location?.name, + // @ts-ignore + address: context.from_location?.address, + }, + // @ts-ignore + to_address: context.shipping_address, + // @ts-ignore + items: context.items || [], + // @ts-ignore + currency_code: context.currency_code, + }) + shipment_id = shipment.shipment_id + } + + return { + ...data, + shipment_id, + } + } +} +``` + +The `validateFulfillmentData` method accepts the following parameters: + +1. The `data` property of the chosen shipping option during checkout. It will hold the carrier ID and its service code. +2. The `data` property of the shipping method to be created. This can hold custom data sent in the [Add Shipping Method API route](https://docs.medusajs.com/api/store#carts_postcartsidshippingmethods). +3. An object of the checkout's context, including the cart's items, the location associated with the shipping option, and more. + +In the method, you try to retrieve the shipment ID from the shipping method's `data` parameter if it was already created.

You include in it the ID of the shipment in ShipStation. + +#### createFulfillment + +After the customer places the order, the admin user can manage its fulfillments. When the admin user creates a fulfillment for the order, Medusa uses the `createFulfillment` method of the associated provider to handle any processing in the third-party provider. + +This method supports creating split fulfillments, meaning you can partially fulfill and order's items. So, you'll create a new shipment, then purchase a label for that shipment. You'll use the existing shipment to retrieve details like the address to ship from and to. + +First, add a new type to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" +export type Label = { + label_id: string + status: "processing" | "completed" | "error" | "voided" + shipment_id: string + ship_date: Date + shipment_cost: { + currency: string + amount: number + } + insurance_cost: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + tracking_number: string + is_return_label: boolean + carrier_id: string + service_code: string + trackable: string + tracking_status: "unknown" | "in_transit" | "error" | "delivered" + label_download: { + href: string + pdf: string + png: string + zpl: string + } +} +``` + +You add the `Label` type for the details in a label object.
