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.

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. - - -# Extend Core Commerce Features - -In the upcoming chapters, you'll learn about the concepts and tools to extend Medusa's core commerce features. - -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 Medusa Framework and orchestration tools mitigate these issues while supporting all your customization needs: - -- [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. - -*** - -## Next Chapters: Link Brands to Products Example - -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: - -- Link brands from the custom [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) to products from Medusa's [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md). -- Extend the core product-creation workflow and the API route that uses it to allow setting the brand of a newly created product. -- Retrieve a product's associated brand's details. - - -# 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. - -*** - -## Next Chapters: Sync Brands Example - -In the previous chapters, you've [added brands](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) to your Medusa application.

Sync brands from the CMS at a daily schedule. - - -# Re-Use Customizations with Plugins - -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. - -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 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. - -![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) - -Medusa provides the tooling to create a plugin package, test it in a local Medusa application, and publish it to NPM. - -To learn more about plugins and how to create them, refer to [this chapter](https://docs.medusajs.com/learn/fundamentals/plugins/index.html.md). - - -# Customize Medusa Admin Dashboard - -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). - -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: - -- 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). - -From these customizations, you can send requests to custom API routes, allowing admin users to manage custom resources on the dashboard - -*** - -## Next Chapters: View Brands in Dashboard - -In the next chapters, you'll continue with the brands example to: - -- 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. - - -# Customizations Next Steps: Learn the Fundamentals - -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. - -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. - -## Useful Guides - -The following guides and references are useful for your development journey: - -3.

When configured, it reports traces for: - -- HTTP requests -- Workflow executions -- Query usages -- Database queries and operations - -*** - -## How to Configure Instrumentation in Medusa? - -### Prerequisites - -- [An exporter to visualize your application's traces, such as Zipkin.](https://zipkin.io/pages/quickstart.html) - -### Install Dependencies - -Start by installing the following OpenTelemetry dependencies in your Medusa project: - -```bash npm2yarn -npm install @opentelemetry/sdk-node @opentelemetry/resources @opentelemetry/sdk-trace-node @opentelemetry/instrumentation-pg -``` - -Also, install the dependencies relevant for the exporter you use. If you're using Zipkin, install the following dependencies: - -```bash npm2yarn -npm install @opentelemetry/exporter-zipkin -``` - -### Add instrumentation.ts - -Next, create the file `instrumentation.ts` with the following content: - -```ts title="instrumentation.ts" -import { registerOtel } from "@medusajs/medusa" -import { ZipkinExporter } from "@opentelemetry/exporter-zipkin" - -// If using an exporter other than Zipkin, initialize it here. -const exporter = new ZipkinExporter({ - serviceName: "my-medusa-project", -}) - -export function register() { - registerOtel({ - serviceName: "medusajs", - // pass exporter - exporter, - instrument: { - http: true, - workflows: true, - query: true, - }, - }) -} -``` - -In the `instrumentation.ts` file, you export a `register` function that uses Medusa's `registerOtel` utility function. You also initialize an instance of the exporter, such as Zipkin, and pass it to the `registerOtel` function. - -`registerOtel` accepts an object where you can pass any [NodeSDKConfiguration](https://open-telemetry.github.io/opentelemetry-js/interfaces/_opentelemetry_sdk_node.NodeSDKConfiguration.html) property along with the following properties: - -The `NodeSDKConfiguration` properties are accepted since Medusa v2.5.1. - -- serviceName: (\`string\`) The name of the service traced. -- exporter: (\[SpanExporter]\(https://open-telemetry.github.io/opentelemetry-js/interfaces/\_opentelemetry\_sdk\_trace\_base.SpanExporter.html)) An instance of an exporter, such as Zipkin. -- instrument: (\`object\`) Options specifying what to trace. - - - http: (\`boolean\`) Whether to trace HTTP requests. - - - query: (\`boolean\`) Whether to trace Query usages. - - - workflows: (\`boolean\`) Whether to trace Workflow executions. - - - db: (\`boolean\`) Whether to trace database queries and operations. -- instrumentations: (\[Instrumentation\[]]\(https://open-telemetry.github.io/opentelemetry-js/interfaces/\_opentelemetry\_instrumentation.Instrumentation.html)) Additional instrumentation options that OpenTelemetry accepts. - -*** - -## Test it Out - -To test it out, start your exporter, such as Zipkin. - -Then, start your Medusa application: - -```bash npm2yarn -npm run dev -``` - -Try to open the Medusa Admin or send a request to an API route. - -If you check traces in your exporter, you'll find new traces reported. - -### Trace Span Names - -Trace span names start with the following keywords based on what it's reporting: - -- `{methodName} {URL}` when reporting HTTP requests, where `{methodName}` is the HTTP method, and `{URL}` is the URL the request is sent to. -- `route:` when reporting route handlers running on an HTTP request. -- `middleware:` when reporting a middleware running on an HTTP request. -- `workflow:` when reporting a workflow execution. -- `step:` when reporting a step in a workflow execution. -- `query.graph:` when reporting Query usages. -- `pg.query:` when reporting database queries and operations. - - -# 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. - -## @medusajs/test-utils Package - -Medusa provides a Testing Framework to create integration tests for your custom API routes, modules, or other Medusa customizations. - -To use the Testing Framework, install `@medusajs/test-utils` as a `devDependency`: - -```bash npm2yarn -npm install --save-dev @medusajs/test-utils@latest -``` - -*** - -## Install and Configure Jest - -Writing tests with `@medusajs/test-utils`'s tools requires installing and configuring Jest in your project. - -Run the following command to install the required Jest dependencies: - -```bash npm2yarn -npm install --save-dev jest @types/jest @swc/jest -``` - -Then, create the file `jest.config.js` with the following content: - -```js title="jest.config.js" -const { loadEnv } = require("@medusajs/framework/utils") -loadEnv("test", process.cwd()) - -module.exports = { - transform: { - "^.+\\.[jt]s$": [ - "@swc/jest", - { - jsc: { - parser: { syntax: "typescript", decorators: true }, - }, - }, - ], - }, - testEnvironment: "node", - moduleFileExtensions: ["js", "ts", "json"], - modulePathIgnorePatterns: ["dist/"], - setupFiles: ["./integration-tests/setup.js"], -} - -if (process.env.TEST_TYPE === "integration:http") { - module.exports.testMatch = ["**/integration-tests/http/*.spec.[jt]s"] -} else if (process.env.TEST_TYPE === "integration:modules") { - module.exports.testMatch = ["**/src/modules/*/__tests__/**/*.[jt]s"] -} else if (process.env.TEST_TYPE === "unit") { - module.exports.testMatch = ["**/src/**/__tests__/**/*.unit.spec.[jt]s"] -} -``` - -Next, create the `integration-tests/setup.js` file with the following content: - -```js title="integration-tests/setup.js" -const { MetadataStorage } = require("@mikro-orm/core") - -MetadataStorage.clear() -``` - -*** - -## Add Test Commands - -Finally, add the following scripts to `package.json`: - -```json title="package.json" -"scripts": { - // ... - "test:integration:http": "TEST_TYPE=integration:http NODE_OPTIONS=--experimental-vm-modules jest --silent=false --runInBand --forceExit", - "test:integration:modules": "TEST_TYPE=integration:modules NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit", - "test:unit": "TEST_TYPE=unit NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit" -}, -``` - -You now have two commands: - -- `test:integration:http` to run integration tests (for example, for API routes and workflows) available under the `integration-tests/http` directory. -- `test:integration:modules` to run integration tests for modules available in any `__tests__` directory under `src/modules`. -- `test:unit` to run unit tests in any `__tests__` directory under the `src` directory. - -Medusa's Testing Framework works for integration tests only.

So, storefronts, admin dashboards, and other clients consume Medusa's functionalities through its API routes. - -In a common Medusa application, requests go through four layers in the stack. 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. It shows a storefront and an admin that can send a request to the HTTP layer. The HTTP layer then uses workflows to handle the business logic. Finally, the workflows use modules to query and manipulate data in the data stores.](https://res.cloudinary.com/dza7lstvk/image/upload/v1727175296/Medusa%20Book/http-layer_sroafr.jpg) - -*** - -## Database Layer - -The Medusa application injects into each module, including your [custom modules](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md), a connection to the configured PostgreSQL database.

The object has a required property `testSuite`. + +`testSuite`'s value is a function that defines the tests to run. The function accepts as a parameter an object that has the following properties: + +- `api`: a set of utility methods used to send requests to the Medusa application. It has the following methods: + - `get`: Send a `GET` request to an API route. + - `post`: Send a `POST` request to an API route. + - `delete`: Send a `DELETE` request to an API route. +- `getContainer`: a function that retrieves the Medusa Container. Use the `getContainer().resolve` method to resolve resources from the Medusa Container. + +The tests in the `testSuite` function are written using [Jest](https://jestjs.io/). + +### Jest Timeout + +Since your tests connect to the database and perform actions that require more time than the typical tests, make sure to increase the timeout in your test: + +```ts title="integration-tests/http/test.spec.ts" +// in your test's file +jest.setTimeout(60 * 1000) +``` + +*** + +### Run Tests + +Run the following command to run your tests: + +```bash npm2yarn +npm run test:integration +``` + +If you don't have a `test:integration` script in `package.json`, refer to the [Medusa Testing Tools chapter](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools#add-test-commands/index.html.md). + +This runs your Medusa application and runs the tests available under the `src/integrations/http` directory. + +*** + +## Other Options and Inputs + +Refer to [the Test Tooling Reference](https://docs.medusajs.com/resources/test-tools-reference/medusaIntegrationTestRunner/index.html.md) for other available parameter options and inputs of the `testSuite` function. + +*** + +## Database Used in Tests + +The `medusaIntegrationTestRunner` function creates a database with a random name before running the tests.

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. + + +# Write Tests for Modules + +In this chapter, you'll learn about `moduleIntegrationTestRunner` from Medusa's Testing Framework and how to use it to write integration tests for a module's main service. + +### Prerequisites + +- [Testing Tools Setup](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools/index.html.md) + +## moduleIntegrationTestRunner Utility + +`moduleIntegrationTestRunner` creates integration tests for a module.

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. + +![Diagram showcasing an overview of the Brand Module](https://res.cloudinary.com/dza7lstvk/image/upload/v1746546820/Medusa%20Resources/brand-module_pg86gm.jpg) + +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. + + +# 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.

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.

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: 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.

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.

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.

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.

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.

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.

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.

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.

In addition, you must have `@swc/core` as a `devDependency`, as it's used by the plugin CLI tools. + +For example, assuming `2.5.0` is the latest Medusa version: + +```json title="package.json" +{ + "devDependencies": { + "@medusajs/admin-sdk": "2.5.0", + "@medusajs/cli": "2.5.0", + "@medusajs/framework": "2.5.0", + "@medusajs/medusa": "2.5.0", + "@medusajs/test-utils": "2.5.0", + "@medusajs/ui": "4.0.4", + "@medusajs/icons": "2.5.0", + "@swc/core": "1.5.7", + }, + "peerDependencies": { + "@medusajs/admin-sdk": "2.5.0", + "@medusajs/cli": "2.5.0", + "@medusajs/framework": "2.5.0", + "@medusajs/test-utils": "2.5.0", + "@medusajs/medusa": "2.5.0", + "@medusajs/ui": "4.0.3", + "@medusajs/icons": "2.5.0", + } +} +``` + +### Package Exports + +Your plugin project will already have the exports mentioned in this section. Unless you made changes to the exports or you created your plugin before [Medusa v2.7.0](https://github.com/medusajs/medusa/releases/tag/v2.7.0), you can skip this section. + +In the `package.json` file, make sure your plugin has the following exports: + +```json title="package.json" +{ + "exports": { + "./package.json": "./package.json", + "./workflows": "./.medusa/server/src/workflows/index.js", + "./.medusa/server/src/modules/*": "./.medusa/server/src/modules/*/index.js", + "./providers/*": "./.medusa/server/src/providers/*/index.js", + "./admin": { + "import": "./.medusa/server/src/admin/index.mjs", + "require": "./.medusa/server/src/admin/index.js", + "default": "./.medusa/server/src/admin/index.js" + }, + "./*": "./.medusa/server/src/*.js" + } +} +``` + +Aside from the `./package.json`, `./providers`, and `./admin`, these exports are only a recommendation. You can cherry-pick the files and directories you want to export. + +The plugin exports the following files and directories: + +- `./package.json`: The `package.json` file. Medusa needs to access the `package.json` when registering the plugin. +- `./workflows`: The workflows exported in `./src/workflows/index.ts`. +- `./.medusa/server/src/modules/*`: The definition file of modules. This is useful if you create links to the plugin's modules in the Medusa application. +- `./providers/*`: The definition file of module providers. This is useful if your plugin includes a module provider, allowing you to register the plugin's providers in Medusa applications. Learn more in the [Create Module Providers](#create-module-providers) section. +- `./admin`: The admin extensions exported in `./src/admin/index.ts`. +- `./*`: Any other files in the plugin's `src` directory. + +*** + +## 3. Publish Plugin Locally for Development and Testing + +Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. + +### Publish and Install Local Package + +### Prerequisites + +- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) + +The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. + +To publish the plugin to the local registry, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:publish +``` + +This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. + +Next, navigate to your Medusa application: + +```bash title="Medusa application" +cd ~/path/to/medusa-app +``` + +Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. + +Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: + +```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" +npm install --save-dev yalc +``` + +After that, run the following Medusa CLI command to install the plugin: + +```bash title="Medusa application" +npx medusa plugin:add @myorg/plugin-name +``` + +Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. + +### Register Plugin in Medusa Application + +After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. + +Add the plugin to the `plugins` array in the `medusa-config.ts` file: + +```ts title="medusa-config.ts" highlights={pluginHighlights} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: {}, + }, + ], +}) +``` + +The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. + +#### Pass Module Options through Plugin + +Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. + +For example: + +```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: { + apiKey: true, + }, + }, + ], +}) +``` + +The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). + +### Watch Plugin Changes During Development + +While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. + +To do that, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:develop +``` + +This command will: + +- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. +- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. + +### Start Medusa Application + +You can start your Medusa application's development server to test out your plugin: + +```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" +npm run dev +``` + +While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. + +*** + +## 4. Create Customizations in the Plugin + +You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. + +- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) +- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) +- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) +- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) +- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) +- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) +- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) +- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) +- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) + +While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). + +### Generating Migrations for Modules + +During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: + +```plain title="Plugin project" +DB_USERNAME=postgres +DB_PASSWORD=123... +DB_HOST=localhost +DB_PORT=5432 +DB_NAME=db_name +``` + +You can add these environment variables in a `.env` file in your plugin project. The variables are: + +- `DB_USERNAME`: The username of the PostgreSQL user to connect to the database. +- `DB_PASSWORD`: The password of the PostgreSQL user to connect to the database. +- `DB_HOST`: The host of the PostgreSQL database. Typically, it's `localhost` if you're running the database locally. +- `DB_PORT`: The port of the PostgreSQL database. Typically, it's `5432` if you're running the database locally. +- `DB_NAME`: The name of the PostgreSQL database to connect to. + +Then, run the following command in your plugin project to generate migrations for the modules in your plugin: + +```bash title="Plugin project" +npx medusa plugin:db:generate +``` + +This command generates migrations for all modules in the plugin. + +Finally, run these migrations on the Medusa application that the plugin is installed in using the `db:migrate` command: + +```bash title="Medusa application" +npx medusa db:migrate +``` + +The migrations in your application, including your plugin, will run and update the database. + +### Importing Module Resources + +In the [Prepare Plugin](#2-prepare-plugin) section, you learned about [exported resources](#package-exports) in your plugin. + +These exports allow you to import your plugin resources in your Medusa application, including workflows, links and modules. + +For example, to import the plugin's workflow in your Medusa application: + +`@myorg/plugin-name` is the plugin package's name. ```ts -export default defineLink( - BlogModule.linkable.post, - ProductModule.linkable.product -) +import { Workflow1, Workflow2 } from "@myorg/plugin-name/workflows" +import BlogModule from "@myorg/plugin-name/modules/blog" +// import other files created in plugin like ./src/types/blog.ts +import BlogType from "@myorg/plugin-name/types/blog" ``` +### Create Module Providers + +The [exported resources](#package-exports) also allow you to import module providers in your plugin and register them in the Medusa application's configuration. A module provider is a module that provides the underlying logic or integration related to a commerce or Infrastructure Module. + +For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/index.html.md) called `my-notification`, you can register it in your Medusa application's configuration like this: + +`@myorg/plugin-name` is the plugin package's name. + +```ts highlights={[["9"]]} title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + { + resolve: "@myorg/plugin-name/providers/my-notification", + id: "my-notification", + options: { + channels: ["email"], + // provider options... + }, + }, + ], + }, + }, + ], +}) +``` + +You pass to `resolve` the path to the provider relative to the plugin package. So, in this example, the `my-notification` provider is located in `./src/providers/my-notification/index.ts` of the plugin. + +To learn how to create module providers, refer to the following guides: + +- [File Module Provider](https://docs.medusajs.com/resources/references/file-provider-module/index.html.md) +- [Notification Module Provider](https://docs.medusajs.com/resources/references/notification-provider-module/index.html.md) +- [Auth Module Provider](https://docs.medusajs.com/resources/references/auth/provider/index.html.md) +- [Payment Module Provider](https://docs.medusajs.com/resources/references/payment/provider/index.html.md) +- [Fulfillment Module Provider](https://docs.medusajs.com/resources/references/fulfillment/provider/index.html.md) +- [Tax Module Provider](https://docs.medusajs.com/resources/references/tax/provider/index.html.md) + +*** + +## 5. Publish Plugin to NPM + +Make sure to add the keywords mentioned in the [Package Keywords](#package-keywords) section in your plugin's `package.json` file. + +Medusa's CLI tool provides a command that bundles your plugin to be published to npm. Once you're ready to publish your plugin publicly, run the following command in your plugin project: + +```bash +npx medusa plugin:build +``` + +The command will compile an output in the `.medusa/server` directory. + +You can now publish the plugin to npm using the [NPM CLI tool](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm). Run the following command to publish the plugin to npm: + +```bash +npm publish +``` + +If you haven't logged in before with your NPM account, you'll be asked to log in first. Then, your package is published publicly to be used in any Medusa application. + +### Install Public Plugin in Medusa Application + +You install a plugin that's published publicly using your package manager. For example: + +```bash npm2yarn +npm install @myorg/plugin-name +``` + +Where `@myorg/plugin-name` is the name of your plugin as published on NPM. + +Then, register the plugin in your Medusa application's configurations as explained in [this section](#register-plugin-in-medusa-application). + +*** + +## Update a Published Plugin + +To update the Medusa dependencies in a plugin, refer to [this documentation](https://docs.medusajs.com/learn/update#update-plugin-project/index.html.md). + +If you've published a plugin and you've made changes to it, you'll have to publish the update to NPM again. + +First, run the following command to change the version of the plugin: + +```bash +npm version +``` + +Where `` indicates the type of version update you’re publishing. For example, it can be `major` or `minor`. Refer to the [npm version documentation](https://docs.npmjs.com/cli/v10/commands/npm-version) for more information. + +Then, re-run the same commands for publishing a plugin: + +```bash +npx medusa plugin:build +npm publish +``` + +This will publish an updated version of your plugin under a new version. + # Add Columns to a Link Table @@ -9215,6 +11989,271 @@ await link.create({ ``` +# 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).

Create a Plugin Project - -Plugins are created in a separate Medusa project. This makes the development and publishing of the plugin easier. Later, you'll install that plugin in your Medusa application to test it out and use it. - -Medusa's `create-medusa-app` CLI tool provides the option to create a plugin project. Run the following command to create a new plugin project: - -```bash -npx create-medusa-app my-plugin --plugin -``` - -This will create a new Medusa plugin project in the `my-plugin` directory. - -### Plugin Directory Structure - -After the installation is done, the plugin structure will look like this: - -![Directory structure of a plugin project](https://res.cloudinary.com/dza7lstvk/image/upload/v1737019441/Medusa%20Book/project-dir_q4xtri.jpg) - -- `src/`: Contains the Medusa customizations. -- `src/admin`: Contains [admin extensions](https://docs.medusajs.com/learn/fundamentals/admin/index.html.md). -- `src/api`: Contains [API routes](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) and [middlewares](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md).

Prepare Plugin - -### Package Name - -Before developing, testing, and publishing your plugin, make sure its name in `package.json` is correct. This is the name you'll use to install the plugin in your Medusa application. - -For example: - -```json title="package.json" -{ - "name": "@myorg/plugin-name", - // ... -} -``` - -### Package Keywords - -Medusa scrapes NPM for a list of plugins that integrate third-party services, to later showcase them on the Medusa website. If you want your plugin to appear in that listing, make sure to add the `medusa-v2` and `medusa-plugin-integration` keywords to the `keywords` field in `package.json`. - -Only plugins that integrate third-party services are listed in the Medusa integrations page. If your plugin doesn't integrate a third-party service, you can skip this step. - -```json title="package.json" -{ - "keywords": [ - "medusa-plugin-integration", - "medusa-v2" - ], - // ... -} -``` - -In addition, make sure to use one of the following keywords based on your integration type: - -|Keyword|Description|Example| -|---|---|---| -|\`medusa-plugin-analytics\`|Analytics service integration|Google Analytics| -|\`medusa-plugin-auth\`|Authentication service integration|Auth0| -|\`medusa-plugin-cms\`|CMS service integration|Contentful| -|\`medusa-plugin-notification\`|Notification service integration|Twilio SMS| -|\`medusa-plugin-payment\`|Payment service integration|PayPal| -|\`medusa-plugin-search\`|Search service integration|MeiliSearch| -|\`medusa-plugin-shipping\`|Shipping service integration|DHL| -|\`medusa-plugin-other\`|Other third-party integrations|Sentry| - -### Package Dependencies - -Your plugin project will already have the dependencies mentioned in this section. Unless you made changes to the dependencies, you can skip this section. - -In the `package.json` file you must have the Medusa dependencies as `devDependencies` and `peerDependencies`. In addition, you must have `@swc/core` as a `devDependency`, as it's used by the plugin CLI tools. - -For example, assuming `2.5.0` is the latest Medusa version: - -```json title="package.json" -{ - "devDependencies": { - "@medusajs/admin-sdk": "2.5.0", - "@medusajs/cli": "2.5.0", - "@medusajs/framework": "2.5.0", - "@medusajs/medusa": "2.5.0", - "@medusajs/test-utils": "2.5.0", - "@medusajs/ui": "4.0.4", - "@medusajs/icons": "2.5.0", - "@swc/core": "1.5.7", - }, - "peerDependencies": { - "@medusajs/admin-sdk": "2.5.0", - "@medusajs/cli": "2.5.0", - "@medusajs/framework": "2.5.0", - "@medusajs/test-utils": "2.5.0", - "@medusajs/medusa": "2.5.0", - "@medusajs/ui": "4.0.3", - "@medusajs/icons": "2.5.0", - } -} -``` - -### Package Exports - -Your plugin project will already have the exports mentioned in this section. Unless you made changes to the exports or you created your plugin before [Medusa v2.7.0](https://github.com/medusajs/medusa/releases/tag/v2.7.0), you can skip this section. - -In the `package.json` file, make sure your plugin has the following exports: - -```json title="package.json" -{ - "exports": { - "./package.json": "./package.json", - "./workflows": "./.medusa/server/src/workflows/index.js", - "./.medusa/server/src/modules/*": "./.medusa/server/src/modules/*/index.js", - "./providers/*": "./.medusa/server/src/providers/*/index.js", - "./admin": { - "import": "./.medusa/server/src/admin/index.mjs", - "require": "./.medusa/server/src/admin/index.js", - "default": "./.medusa/server/src/admin/index.js" - }, - "./*": "./.medusa/server/src/*.js" - } -} -``` - -Aside from the `./package.json`, `./providers`, and `./admin`, these exports are only a recommendation. You can cherry-pick the files and directories you want to export. - -The plugin exports the following files and directories: - -- `./package.json`: The `package.json` file. Medusa needs to access the `package.json` when registering the plugin. -- `./workflows`: The workflows exported in `./src/workflows/index.ts`. -- `./.medusa/server/src/modules/*`: The definition file of modules. This is useful if you create links to the plugin's modules in the Medusa application. -- `./providers/*`: The definition file of module providers. This is useful if your plugin includes a module provider, allowing you to register the plugin's providers in Medusa applications. Learn more in the [Create Module Providers](#create-module-providers) section. -- `./admin`: The admin extensions exported in `./src/admin/index.ts`. -- `./*`: Any other files in the plugin's `src` directory. - -*** - -## 3. Publish Plugin Locally for Development and Testing - -Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. - -### Publish and Install Local Package - -### Prerequisites - -- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) - -The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. - -To publish the plugin to the local registry, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:publish -``` - -This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. - -Next, navigate to your Medusa application: - -```bash title="Medusa application" -cd ~/path/to/medusa-app -``` - -Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. - -Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm install --save-dev yalc -``` - -After that, run the following Medusa CLI command to install the plugin: - -```bash title="Medusa application" -npx medusa plugin:add @myorg/plugin-name -``` - -Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. - -### Register Plugin in Medusa Application - -After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. - -Add the plugin to the `plugins` array in the `medusa-config.ts` file: - -```ts title="medusa-config.ts" highlights={pluginHighlights} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: {}, - }, - ], -}) -``` - -The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. - -#### Pass Module Options through Plugin - -Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. - -For example: - -```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: { - apiKey: true, - }, - }, - ], -}) -``` - -The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). - -### Watch Plugin Changes During Development - -While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. - -To do that, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:develop -``` - -This command will: - -- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. -- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. - -### Start Medusa Application - -You can start your Medusa application's development server to test out your plugin: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm run dev -``` - -While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. - -*** - -## 4. Create Customizations in the Plugin - -You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. - -- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) -- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) -- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) -- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) -- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) -- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) -- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) -- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) -- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) - -While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). - -### Generating Migrations for Modules - -During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: - -```plain title="Plugin project" -DB_USERNAME=postgres -DB_PASSWORD=123... -DB_HOST=localhost -DB_PORT=5432 -DB_NAME=db_name -``` - -You can add these environment variables in a `.env` file in your plugin project. The variables are: - -- `DB_USERNAME`: The username of the PostgreSQL user to connect to the database. -- `DB_PASSWORD`: The password of the PostgreSQL user to connect to the database. -- `DB_HOST`: The host of the PostgreSQL database. Typically, it's `localhost` if you're running the database locally. -- `DB_PORT`: The port of the PostgreSQL database. Typically, it's `5432` if you're running the database locally. -- `DB_NAME`: The name of the PostgreSQL database to connect to. - -Then, run the following command in your plugin project to generate migrations for the modules in your plugin: - -```bash title="Plugin project" -npx medusa plugin:db:generate -``` - -This command generates migrations for all modules in the plugin. - -Finally, run these migrations on the Medusa application that the plugin is installed in using the `db:migrate` command: - -```bash title="Medusa application" -npx medusa db:migrate -``` - -The migrations in your application, including your plugin, will run and update the database. - -### Importing Module Resources - -In the [Prepare Plugin](#2-prepare-plugin) section, you learned about [exported resources](#package-exports) in your plugin. - -These exports allow you to import your plugin resources in your Medusa application, including workflows, links and modules. - -For example, to import the plugin's workflow in your Medusa application: - -`@myorg/plugin-name` is the plugin package's name. - -```ts -import { Workflow1, Workflow2 } from "@myorg/plugin-name/workflows" -import BlogModule from "@myorg/plugin-name/modules/blog" -// import other files created in plugin like ./src/types/blog.ts -import BlogType from "@myorg/plugin-name/types/blog" -``` - -### Create Module Providers - -The [exported resources](#package-exports) also allow you to import module providers in your plugin and register them in the Medusa application's configuration. A module provider is a module that provides the underlying logic or integration related to a commerce or Infrastructure Module. - -For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/index.html.md) called `my-notification`, you can register it in your Medusa application's configuration like this: - -`@myorg/plugin-name` is the plugin package's name. - -```ts highlights={[["9"]]} title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - { - resolve: "@myorg/plugin-name/providers/my-notification", - id: "my-notification", - options: { - channels: ["email"], - // provider options... - }, - }, - ], - }, - }, - ], -}) -``` - -You pass to `resolve` the path to the provider relative to the plugin package. So, in this example, the `my-notification` provider is located in `./src/providers/my-notification/index.ts` of the plugin. - -To learn how to create module providers, refer to the following guides: - -- [File Module Provider](https://docs.medusajs.com/resources/references/file-provider-module/index.html.md) -- [Notification Module Provider](https://docs.medusajs.com/resources/references/notification-provider-module/index.html.md) -- [Auth Module Provider](https://docs.medusajs.com/resources/references/auth/provider/index.html.md) -- [Payment Module Provider](https://docs.medusajs.com/resources/references/payment/provider/index.html.md) -- [Fulfillment Module Provider](https://docs.medusajs.com/resources/references/fulfillment/provider/index.html.md) -- [Tax Module Provider](https://docs.medusajs.com/resources/references/tax/provider/index.html.md) - -*** - -## 5. Publish Plugin to NPM - -Make sure to add the keywords mentioned in the [Package Keywords](#package-keywords) section in your plugin's `package.json` file. - -Medusa's CLI tool provides a command that bundles your plugin to be published to npm. Once you're ready to publish your plugin publicly, run the following command in your plugin project: - -```bash -npx medusa plugin:build -``` - -The command will compile an output in the `.medusa/server` directory. - -You can now publish the plugin to npm using the [NPM CLI tool](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm). Run the following command to publish the plugin to npm: - -```bash -npm publish -``` - -If you haven't logged in before with your NPM account, you'll be asked to log in first. Then, your package is published publicly to be used in any Medusa application. - -### Install Public Plugin in Medusa Application - -You install a plugin that's published publicly using your package manager. For example: - -```bash npm2yarn -npm install @myorg/plugin-name -``` - -Where `@myorg/plugin-name` is the name of your plugin as published on NPM. - -Then, register the plugin in your Medusa application's configurations as explained in [this section](#register-plugin-in-medusa-application). - -*** - -## Update a Published Plugin - -To update the Medusa dependencies in a plugin, refer to [this documentation](https://docs.medusajs.com/learn/update#update-plugin-project/index.html.md). - -If you've published a plugin and you've made changes to it, you'll have to publish the update to NPM again. - -First, run the following command to change the version of the plugin: - -```bash -npm version -``` - -Where `` indicates the type of version update you’re publishing. For example, it can be `major` or `minor`. Refer to the [npm version documentation](https://docs.npmjs.com/cli/v10/commands/npm-version) for more information. - -Then, re-run the same commands for publishing a plugin: - -```bash -npx medusa plugin:build -npm publish -``` - -This will publish an updated version of your plugin under a new version. - - # Module Container In this chapter, you'll learn about the module's container and how to resolve resources in that container. @@ -11858,6 +14289,38 @@ class BlogModuleService { ``` +# Infrastructure Modules + +In this chapter, you’ll learn about Infrastructure Modules. + +## What is an Infrastructure Module? + +An Infrastructure Module implements features and mechanisms related to the Medusa application’s architecture and infrastructure. + +Since modules are interchangeable, you have more control over Medusa’s architecture.

The error’s name is `TransactionStepTimeoutError`. -# Guide: Create Brand API Route - -In the previous two chapters, you created a [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) that added the concepts of brands to your application, then created a [workflow to create a brand](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). 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, 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?

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. - -![Diagram showcasing an overview of the Brand Module](https://res.cloudinary.com/dza7lstvk/image/upload/v1746546820/Medusa%20Resources/brand-module_pg86gm.jpg) - -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. - - -# 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: 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. - - -# 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: 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: 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: 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.

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 also add two tiered prices that set the price to `$8` when the quantity is between `10` and `19`, and to `$6` when the quantity is `20` or more. - -### How are Tiered Prices Applied? - -The [price calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) mechanism considers the cart's items as a context when choosing the best price to apply. - -For example, consider the customer added the `variant_1` product variant (created in the workflow snippet of the [above section](#how-to-create-tiered-prices)) to their cart with a quantity of `15`. - -The price calculation mechanism will choose the second price, which is `$8`, because the quantity of `15` is between `10` and `19`. - -If there are other rules applied to the price, they may affect the price calculation. Keep reading to learn about other price rules, and refer to the [Price Calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) guide for more details on the calculation mechanism. - -*** - -## Price Rule - -You can also restrict prices by advanced rules, such as a customer's group, zip code, or a cart's total. - -Each rule of a price is represented by the [PriceRule data model](https://docs.medusajs.com/references/pricing/models/PriceRule/index.html.md). - -The `Price` data model has a `rules_count` property, which indicates how many rules, represented by `PriceRule`, are applied to the price. - -For exmaple, you create a price restricted to `10557` zip codes. - -![A diagram showcasing the relation between the PriceRule and Price](https://res.cloudinary.com/dza7lstvk/image/upload/v1709648772/Medusa%20Resources/price-rule-1_vy8bn9.jpg) - -A price can have multiple price rules. - -For example, a price can be restricted by a region and a zip code. - -![A diagram showcasing the relation between the PriceRule and Price with multiple rules.](https://res.cloudinary.com/dza7lstvk/image/upload/v1709649296/Medusa%20Resources/price-rule-3_pwpocz.jpg) - -### Price List Rules - -Rules applied to a price list are represented by the [PriceListRule data model](https://docs.medusajs.com/references/pricing/models/PriceListRule/index.html.md). - -The `rules_count` property of a `PriceList` indicates how many rules are applied to it. - -![A diagram showcasing the relation between the PriceSet, PriceList, Price, RuleType, and PriceListRuleValue](https://res.cloudinary.com/dza7lstvk/image/upload/v1709641999/Medusa%20Resources/price-list_zd10yd.jpg) - -### How to Create Prices with Rules? - -When you create prices, you can specify rules for each price.

When the total of the cart or order using this shipping option is greater than `$100`, the shipping option's price becomes free. - -### How is the Price Rule Applied? - -The [price calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) mechanism considers a price applicable when the resource that this price is in matches the specified rules. - -For example, a [cart object](https://docs.medusajs.com/api/store#carts_cart_schema) has an `item_total` property. So, if a shipping option has the following price: - -```json -{ - "currency_code": "usd", - "amount": 0, - "rules": { - "item_total": { - "operator": "gte", - "value": 100, - } - } -} -``` - -The shipping option's price is applied when the cart's `item_total` is greater than or equal to `$100`. - -You can also apply the rule on nested relations and properties. For example, to apply a shipping option's price based on the customer's group, you can apply a rule on the `customer.group.id` attribute: - -```json -{ - "currency_code": "usd", - "amount": 0, - "rules": { - "customer.group.id": { - "operator": "eq", - "value": "cusgrp_123" - } - } -} -``` - -In this example, the price is only applied if a cart's customer belongs to the customer group of ID `cusgrp_123`. - -These same rules apply to product variant prices as well, or any other resource that has a price. - - -# Tax-Inclusive Pricing - -In this document, you’ll learn about tax-inclusive pricing and how it's used when calculating prices. - -## What is Tax-Inclusive Pricing? - -A tax-inclusive price is a price of a resource that includes taxes. Medusa calculates the tax amount from the price rather than adds the amount to it. - -For example, if a product’s price is $50, the tax rate is 2%, and tax-inclusive pricing is enabled, then the product's price is $49, and the applied tax amount is $1. - -*** - -## How is Tax-Inclusive Pricing Set? - -The [PricePreference data model](https://docs.medusajs.com/references/pricing/models/PricePreference/index.html.md) holds the tax-inclusive setting for a context. It has two properties that indicate the context: - -- `attribute`: The name of the attribute to compare against. For example, `region_id` or `currency_code`. -- `value`: The attribute’s value. For example, `reg_123` or `usd`. - -Only `region_id` and `currency_code` are supported as an `attribute` at the moment. - -The `is_tax_inclusive` property indicates whether tax-inclusivity is enabled in the specified context. - -For example: - -```json -{ - "attribute": "currency_code", - "value": "USD", - "is_tax_inclusive": true, -} -``` - -In this example, tax-inclusivity is enabled for the `USD` currency code. - -*** - -## Tax-Inclusive Pricing in Price Calculation - -### Tax Context - -As mentioned in the [Price Calculation documentation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#calculation-context/index.html.md), The `calculatePrices` method accepts as a parameter a calculation context. - -To get accurate tax results, pass the `region_id` and / or `currency_code` in the calculation context. - -### Returned Tax Properties - -The `calculatePrices` method returns two properties related to tax-inclusivity: - -Learn more about the returned properties in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#returned-price-object/index.html.md). - -- `is_calculated_price_tax_inclusive`: Whether the selected `calculated_price` is tax-inclusive. -- `is_original_price_tax_inclusive` : Whether the selected `original_price` is tax-inclusive. - -A price is considered tax-inclusive if: - -1.

When the total of the cart or order using this shipping option is greater than `$100`, the shipping option's price becomes free. + +### How is the Price Rule Applied? + +The [price calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) mechanism considers a price applicable when the resource that this price is in matches the specified rules. + +For example, a [cart object](https://docs.medusajs.com/api/store#carts_cart_schema) has an `item_total` property. So, if a shipping option has the following price: + +```json +{ + "currency_code": "usd", + "amount": 0, + "rules": { + "item_total": { + "operator": "gte", + "value": 100, + } + } +} +``` + +The shipping option's price is applied when the cart's `item_total` is greater than or equal to `$100`. + +You can also apply the rule on nested relations and properties. For example, to apply a shipping option's price based on the customer's group, you can apply a rule on the `customer.group.id` attribute: + +```json +{ + "currency_code": "usd", + "amount": 0, + "rules": { + "customer.group.id": { + "operator": "eq", + "value": "cusgrp_123" + } + } +} +``` + +In this example, the price is only applied if a cart's customer belongs to the customer group of ID `cusgrp_123`. + +These same rules apply to product variant prices as well, or any other resource that has a price. + + +# Tax-Inclusive Pricing + +In this document, you’ll learn about tax-inclusive pricing and how it's used when calculating prices. + +## What is Tax-Inclusive Pricing? + +A tax-inclusive price is a price of a resource that includes taxes.

For example, when a customer purchases a product variant, the Medusa application decrements the stocked quantity of the product variant. + +This guide explains how to retrieve the inventory quantity of a product variant when `manage_inventory` is enabled. + +*** + +## Retrieve Product Variant Inventory + +To retrieve the inventory quantity of a product variant, use the `getVariantAvailability` utility function imported from `@medusajs/framework/utils`. It returns the available quantity of the product variant. + +For example: + +```ts highlights={variantAvailabilityHighlights} +import { getVariantAvailability } from "@medusajs/framework/utils" + +// ... + +// use req.scope instead of container in API routes +const query = container.resolve("query") + +const availability = await getVariantAvailability(query, { + variant_ids: ["variant_123"], + sales_channel_id: "sc_123", +}) +``` + +A product variant's inventory quantity is set per [stock location](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/stock-location/index.html.md). This stock location is linked to a [sales channel](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/index.html.md). + +So, to retrieve the inventory quantity of a product variant using `getVariantAvailability`, you need to also provide the ID of the sales channel to retrieve the inventory quantity in. + +Refer to the [Retrieve Sales Channel to Use](#retrieve-sales-channel-to-use) section to learn how to retrieve the sales channel ID to use in the `getVariantAvailability` function. + +### Parameters + +The `getVariantAvailability` function accepts the following parameters: + +- query: (Query) Instance of Query to retrieve the necessary data. +- options: (\`object\`) The options to retrieve the variant availability. + + - variant\_ids: (\`string\[]\`) The IDs of the product variants to retrieve their inventory availability. + + - sales\_channel\_id: (\`string\`) The ID of the sales channel to retrieve the variant availability in. + +### Returns + +The `getVariantAvailability` function resolves to an object whose keys are the IDs of each product variant passed in the `variant_ids` parameter. + +The value of each key is an object with the following properties: + +- availability: (\`number\`) The available quantity of the product variant in the stock location linked to the sales channel. If \`manage\_inventory\` is disabled, this value is \`0\`. +- sales\_channel\_id: (\`string\`) The ID of the sales channel that the availability is scoped to. + +For example, the object may look like this: + +```json title="Example result" +{ + "variant_123": { + "availability": 10, + "sales_channel_id": "sc_123" + } +} +``` + +*** + +## Retrieve Sales Channel to Use + +To retrieve the sales channel ID to use in the `getVariantAvailability` function, you can either: + +- Use the sales channel of the request's scope. +- Use the sales channel that the variant's product is available in. + +### Method 1: Use Sales Channel Scope in Store Routes + +Requests sent to API routes starting with `/store` must include a [publishable API key in the request header](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/publishable-api-keys/index.html.md). This scopes the request to one or more sales channels associated with the publishable API key. + +So, if you're retrieving the variant inventory availability in an API route starting with `/store`, you can access the sales channel using the `publishable_key_context.sales_channel_ids` property of the request object: + +```ts highlights={salesChannelScopeHighlights} +import { MedusaStoreRequest, MedusaResponse } from "@medusajs/framework/http" +import { getVariantAvailability } from "@medusajs/framework/utils" + +export async function GET( + req: MedusaStoreRequest, + res: MedusaResponse +) { + const query = req.scope.resolve("query") + const sales_channel_ids = req.publishable_key_context.sales_channel_ids + + const availability = await getVariantAvailability(query, { + variant_ids: ["variant_123"], + sales_channel_id: sales_channel_ids[0], + }) + + res.json({ + availability, + }) +} +``` + +In this example, you retrieve the scope's sales channel IDs using `req.publishable_key_context.sales_channel_ids`, whose value is an array of IDs. + +Then, you pass the first sales channel ID to the `getVariantAvailability` function to retrieve the inventory availability of the product variant in that sales channel. + +Notice that the request object's type is `MedusaStoreRequest` instead of `MedusaRequest` to ensure the availability of the `publishable_key_context` property. + +### Method 2: Use Product's Sales Channel + +A product is linked to the sales channels it's available in. So, you can retrieve the details of the variant's product, including its sales channels. + +For example: + +```ts highlights={productSalesChannelHighlights} +import { getVariantAvailability } from "@medusajs/framework/utils" + +// ... + +// use req.scope instead of container in API routes +const query = container.resolve("query") + +const { data: variants } = await query.graph({ + entity: "variant", + fields: ["id", "product.sales_channels.*"], + filters: { + id: "variant_123", + }, +}) + +const availability = await getVariantAvailability(query, { + variant_ids: ["variant_123"], + sales_channel_id: variants[0].product!.sales_channels![0]!.id, +}) +``` + +In this example, you retrieve the sales channels of the variant's product using [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md). + +You pass the ID of the variant as a filter, and you specify `product.sales_channels.*` as the fields to retrieve. This retrieves the sales channels linked to the variant's product. + +Then, you pass the first sales channel ID to the `getVariantAvailability` function to retrieve the inventory availability of the product variant in that sales channel. + + ## Workflows -- [addShippingMethodToCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/addShippingMethodToCartWorkflow/index.html.md) --

However, it delegates the actual payment processing to module providers that integrate third-party payment services. + +The [Stripe Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-provider/stripe/index.html.md) is a Payment Module Provider that integrates Stripe into your Medusa application to process payments. It can also save payment methods securely. + +In this section, you'll set up the Stripe Module Provider in your Medusa application. + +### Prerequisites + +- [Stripe account](https://stripe.com/) +- [Stripe Secret and Public API Keys](https://support.stripe.com/questions/locate-api-keys-in-the-dashboard) + +### Register the Stripe Module Provider + +To register the Stripe Module Provider in your Medusa application, add it to the array of providers passed to the Payment Module in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/payment", + options: { + providers: [ + { + resolve: "@medusajs/medusa/payment-stripe", + id: "stripe", + options: { + apiKey: process.env.STRIPE_API_KEY, + }, + }, + ], + }, + }, + ], +}) +``` + +The Medusa configuration accepts a `modules` array, which contains the modules to be loaded. While the Payment Module is loaded by default, you need to add it again when registering a new provider. + +You register provides in the `providers` option of the Payment Module. Each provider is an object with the following properties: + +- `resolve`: The package name of the provider. +- `id`: The ID of the provider. This is used to identify the provider in the Medusa application. +- `options`: The options to be passed to the provider. In this case, the `apiKey` option is required for the Stripe Module Provider. + +Learn about other options in the [Stripe Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-provider/stripe#module-options/index.html.md) documentation. + +### Add Environment Variables + +Next, add the following environment variables to your `.env` file: + +```plain +STRIPE_API_KEY=sk_... +``` + +Where `STRIPE_API_KEY` is your Stripe Secret API Key.

So, after registering the Stripe Module Provider, you need to enable it in a region. + +To enable it in a region, start the Medusa application with the following command: + +```bash npm2yarn +npm run dev +``` + +Then, go to `localhost:9000/app` and log in with the user you created earlier. + +Once you're logged in: + +1.

You can find it in the Stripe dashboard under Developers > API keys. + +*** + +## Step 3: List Payment Methods API Route + +The Payment Module uses [account holders](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/account-holder/index.html.md) to represent a customer's details that are stored in a third-party payment provider. Medusa creates an account holder for each customer, allowing you later to retrieve the customer's saved payment methods in the third-party provider. + +![Diagram illustrating the relation between customers and account holders in Medusa, and customers in Stripe](https://res.cloudinary.com/dza7lstvk/image/upload/v1745314344/Medusa%20Resources/customer-account-stripe_in5ei6.jpg) + +While this feature is available out-of-the-box, you need to expose it to clients, like storefronts, by creating 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. + +In this step, you'll create an API route that lists the saved payment methods for an authenticated customer. + +Refer to the [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md) documentation to learn more. + +### Create API Route + +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`, and it can include path parameters using square brackets. + +So, to create an API route at the path `/store/payment-methods/:account-holder-id`, create the file `src/api/store/payment-methods/[account_holder_id]/route.ts` with the following content: + +```ts title="src/api/store/payment-methods/[account_holder_id]/route.ts" highlights={apiRouteHighlights} +import { MedusaError } from "@medusajs/framework/utils" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export async function GET( + req: MedusaRequest, + res: MedusaResponse +) { + const { account_holder_id } = req.params + const query = req.scope.resolve("query") + const paymentModuleService = req.scope.resolve("payment") + + const { data: [accountHolder] } = await query.graph({ + entity: "account_holder", + fields: [ + "data", + "provider_id", + ], + filters: { + id: account_holder_id, + }, + }) + + if (!accountHolder) { + throw new MedusaError( + MedusaError.Types.NOT_FOUND, + "Account holder not found" + ) + } + + const paymentMethods = await paymentModuleService.listPaymentMethods( + { + provider_id: accountHolder.provider_id, + context: { + account_holder: { + data: { + id: accountHolder.data.id, + }, + }, + }, + } + ) + + res.json({ + payment_methods: paymentMethods, + }) +} +``` + +Since you export a route handler function named `GET`, you expose a `GET` API route at `/store/payment-methods/:account-holder-id`. 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. + +The request object has a `scope` property, which is an instance of the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). The Medusa container is a registry of Framework and commerce tools that you can access in the API route. + +You use the Medusa container to resolve: + +- [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules in the Medusa application. +- The [Payment Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/index.html.md)'s service, which provides an interface to manage and process payments with third-party providers. + +You use Query to retrieve the account holder with the ID passed as a path parameter. If the account holder is not found, you throw an error. + +Then, you use the [listPaymentMethods](https://docs.medusajs.com/references/payment/listPaymentMethods/index.html.md) method of the Payment Module's service to retrieve the payment providers saved in the third-party provider. The method accepts an object with the following properties: + +- `provider_id`: The ID of the provider, such as Stripe's ID. The account holder stores the ID its associated provider. +- `context`: The context of the request. In this case, you pass the account holder's ID to retrieve the payment methods associated with it in the third-party provider. + +Finally, you return the payment methods in the response. + +### Protect API Route + +Only authenticated customers can access and use saved payment methods. So, you need to protect the API route to ensure that only authenticated customers can access it. + +To protect an API route, you can add 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. You can add an authentication middleware that ensures that the request is authenticated before executing the route handler function. + +Refer to the [Middlewares](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) documentation to learn more. + +Middlewares are added in the `src/api/middlewares.ts` file. So, create the file with the following content: + +```ts title="src/api/middlewares.ts" +import { authenticate, defineMiddlewares } from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/payment-methods/:provider_id/:account_holder_id", + method: "GET", + middlewares: [ + authenticate("customer", ["bearer", "session"]), + ], + }, + ], +}) +``` + +The `src/api/middlewares.ts` file must use the `defineMiddlewares` function and export its result. The `defineMiddlewares` function accepts a `routes` array that accepts objects with the following properties: + +- `matcher`: The path of the API route to apply the middleware to. +- `method`: The HTTP method of the API route to apply the middleware to. +- `middlewares`: An array of middlewares to apply to the API route. + +You apply the `authenticate` middleware to the API route you created earlier. The `authenticate` middleware ensures that only authenticated customers can access the API route. + +Refer to the [Protected Routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/protected-routes/index.html.md) documentation to learn more about the `authenticate` middleware. + +Your API route can now only be accessed by authenticated customers. You'll test it out as you customize the Next.js Starter Storefront in the next steps. + +*** + +## Step 4: Save Payment Methods During Checkout + +In this step, you'll customize the checkout flow in the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to save payment methods during checkout. + +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-payment`, you can find the storefront by going back to the parent directory and changing to the `medusa-payment-storefront` directory: + +```bash +cd ../medusa-payment-storefront # change based on your project name +``` + +During checkout, when the customer chooses a payment method, such as Stripe, the Next.js Starter Storefront creates a [payment session](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-session/index.html.md) in Medusa using the [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route. + +Under the hood, Medusa uses the associated payment provider (Stripe) to initiate the payment process with the associated third-party payment provider. The [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route accepts a `data` object parameter in the request body that allows you to pass data relevant to the third-party payment provider. + +So, to save the payment method that the customer uses during checkout with Stripe, you must pass the `setup_future_usage` property in the `data` object. The `setup_future_usage` property is a Stripe-specific property that allows you to save the payment method for future use. + +In `src/modules/checkout/components/payment/index.tsx` of the Next.js Starter Storefront, there are two uses of the `initiatePaymentSession` function. Update each of them to pass the `data` property: + +```ts title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" +// update in two places +await initiatePaymentSession(cart, { + // ... + data: { + setup_future_usage: "off_session", + }, +}) +``` + +You customize the `initiatePaymentSession` function to pass the `data` object with the `setup_future_usage` property. You set the value to `off_session` to allow using the payment method outside of the checkout flow, such as for follow up payments. You can use `on_session` instead if you only want the payment method to be used by the customer during checkout. + +By making this change, you always save the payment method that the customer uses during checkout. You can alternatively show a checkbox to confirm saving the payment method, and only pass the `data` object if the customer checks it. + +### Test it Out + +To test it out, start the Medusa application by running the following command in the Medusa application's directory: + +```bash npm2yarn +npm run dev +``` + +Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: + +```bash npm2yarn +npm run dev +``` + +You can open the storefront in your browser at `localhost:8000`. Then, create a new customer account by clicking on the "Account" link at the top right. + +After creating an account and logging in, add a product to the cart and go to the checkout page. Once you get to the payment step, choose Stripe and enter a [test card number](https://docs.stripe.com/testing#cards), such as `4242 4242 4242 4242`. + +Then, place the order. Once the order is placed, you can check on the Stripe dashboard that the payment method was saved by: + +1. Going to the "Customers" section in the Stripe dashboard. +2. Clicking on the customer you just placed the order with. +3. Scrolling down to the "Payment methods" section. You'll find the payment method you just used to place the order. + +![Saved payment method on the Stripe dashboard](https://res.cloudinary.com/dza7lstvk/image/upload/v1745249064/Medusa%20Resources/Screenshot_2025-04-21_at_6.24.00_PM_peotrd.png) + +In the next step, you'll show the saved payment methods to the customer during checkout and allow them to select one of them. + +*** + +## Step 5: Use Saved Payment Methods During Checkout + +In this step, you'll customize the checkout flow in the Next.js Starter Storefront to show the saved payment methods to the customer and allow them to select one of them to place the order. + +### Retrieve Saved Payment Methods + +To retrieve the saved payment methods, you'll add a server function that retrieves the customer's saved payment methods from the API route you created earlier. + +Add the following in `src/lib/data/payment.ts`: + +```ts title="src/lib/data/payment.ts" badgeLabel="Storefront" badgeColor="blue" highlights={paymentHighlights} +export type SavedPaymentMethod = { + id: string + provider_id: string + data: { + card: { + brand: string + last4: string + exp_month: number + exp_year: number + } + } +} + +export const getSavedPaymentMethods = async (accountHolderId: string) => { + const headers = { + ...(await getAuthHeaders()), + } + + return sdk.client.fetch<{ + payment_methods: SavedPaymentMethod[] + }>( + `/store/payment-methods/${accountHolderId}`, + { + method: "GET", + headers, + } + ).catch(() => { + return { + payment_methods: [], + } + }) +} +``` + +You define a type for the retrieved payment methods. It contains the following properties: + +- `id`: The ID of the payment method in the third-party provider. +- `provider_id`: The ID of the provider in the Medusa application, such as Stripe's ID. +- `data`: Additional data retrieved from the third-party provider related to the saved payment method. The type is modeled after the data returned by Stripe, but you can change it to match other payment providers. + +You also create a `getSavedPaymentMethods` function that retrieves the saved payment methods from the API route you created earlier. The function accepts the account holder ID as a parameter and returns the saved payment methods. + +### Add Saved Payment Methods Component + +Next, you'll add the component that shows the saved payment methods and allows the customer to select one of them. + +The component that shows the Stripe card element is defined in `src/modules/checkout/components/payment-container/index.tsx`. So, you'll define the component for the saved payment methods in the same file. + +Start by adding the following import statements at the top of the file: + +```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +import { Button } from "@medusajs/ui" +import { useEffect, useState } from "react" +import { HttpTypes } from "@medusajs/types" +import { SavedPaymentMethod, getSavedPaymentMethods } from "@lib/data/payment" +import { initiatePaymentSession } from "../../../../lib/data/cart" +import { capitalize } from "lodash" +``` + +Then, update the `PaymentContainerProps` type to include the payment session and cart details: + +```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +type PaymentContainerProps = { + // ... + paymentSession?: HttpTypes.StorePaymentSession + cart: HttpTypes.StoreCart +} +``` + +You'll need these details to find which saved payment method the customer selected, and to initiate a new payment session for the cart when the customer chooses a saved payment method. + +Next, add the following component at the end of the file: + +```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeSavedPaymentMethodsHighlights} +const StripeSavedPaymentMethodsContainer = ({ + paymentSession, + setCardComplete, + setCardBrand, + setError, + cart, +}: { + paymentSession?: HttpTypes.StorePaymentSession + setCardComplete: (complete: boolean) => void + setCardBrand: (brand: string) => void + setError: (error: string | null) => void + cart: HttpTypes.StoreCart +}) => { + const [savedPaymentMethods, setSavedPaymentMethods] = useState< + SavedPaymentMethod[] + >([]) + const [selectedPaymentMethod, setSelectedPaymentMethod] = useState< + string | undefined + >( + paymentSession?.data?.payment_method_id as string | undefined + ) + + useEffect(() => { + const accountHolderId = ( + paymentSession?.context?.account_holder as Record + ) + ?.id + + if (!accountHolderId) { + return + } + + getSavedPaymentMethods(accountHolderId) + .then(({ payment_methods }) => { + setSavedPaymentMethods(payment_methods) + }) + }, [paymentSession]) + + useEffect(() => { + if (!selectedPaymentMethod || !savedPaymentMethods.length) { + setCardComplete(false) + setCardBrand("") + setError(null) + return + } + const selectedMethod = savedPaymentMethods.find( + (method) => method.id === selectedPaymentMethod + ) + + if (!selectedMethod) { + return + } + + setCardBrand(capitalize(selectedMethod.data.card.brand)) + setCardComplete(true) + setError(null) + }, [selectedPaymentMethod, savedPaymentMethods]) + + const handleSelect = async (method: SavedPaymentMethod) => { + // initiate a new payment session with the selected payment method + await initiatePaymentSession(cart, { + provider_id: method.provider_id, + data: { + payment_method_id: method.id, + }, + }).catch((error) => { + setError(error.message) + }) + + setSelectedPaymentMethod(method.id) + } + + if (!savedPaymentMethods.length) { + return <> + } + + // TODO add return statement +} +``` + +You define a `StripeSavedPaymentMethodsContainer` component that accepts the following props: + +- `paymentSession`: The cart's current payment session. +- `setCardComplete`: A function to tell parent components whether the cart or payment method selection is complete. This allows the customer to proceed to the next step in the checkout flow. +- `setCardBrand`: A function to set the brand of the selected payment method. This is useful to show the brand of the selected payment method in review sections of the checkout flow. +- `setError`: A function to set the error message in case of an error. +- `cart`: The cart's details. + +In the component, you define a state variable to store the saved payment methods and another one to store the selected payment method. + +Then, you use the `useEffect` hook to retrieve the saved payment methods for the account holder set in the cart's payment session. You use the `getSavedPaymentMethods` function you created earlier to retrieve the saved payment methods. + +You also use another `useEffect` hook that is executed when the selected payment method changes. In this hook, you check if the selected payment method is valid and set the card brand and completion status accordingly. + +Finally, you define a `handleSelect` function that you'll execute when the customer selects a saved payment method. It creates a new payment session with the selected payment method. + +To show the saved payment methods, replace the `TODO` with the following `return` statement: + +```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +return ( +
+ + Choose a saved payment method: + + {savedPaymentMethods.map((method) => ( +
handleSelect(method)} + > +
+ { + if (e.target.checked) { + handleSelect(method) + } + }} + /> +
+ + {capitalize(method.data.card.brand)} •••• {method.data.card.last4} + + + Expires {method.data.card.exp_month}/{method.data.card.exp_year} + +
+
+
+ ))} +
+) +``` + +You display the saved payment methods as radio buttons. When the customer selects one of them, you execute the `handleSelect` function to initiate a new payment session with the selected payment method. + +### Modify Existing Stripe Element + +Now that you have the component to show the saved payment methods, you need to modify the existing Stripe element to allow customers to select an existing payment method or enter a new one. + +In the same `src/modules/checkout/components/payment-container/index.tsx` file, expand the new `paymentSession` and `cart` props of the `StripeCardContainer` component: + +```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +export const StripeCardContainer = ({ + // ... + paymentSession, + cart, +}: Omit & { + // ... +}) => { + // ... +} +``` + +Then, add a new state variable that keeps track of whether the customer is using a saved payment method or entering a new one: + +```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +const [isUsingSavedPaymentMethod, setIsUsingSavedPaymentMethod] = useState( + paymentSession?.data?.payment_method_id !== undefined +) +``` + +Next, add a function that resets the payment session when the customer switches between saved and new payment methods: + +```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" +const handleRefreshSession = async () => { + await initiatePaymentSession(cart, { + provider_id: paymentProviderId, + }) + setIsUsingSavedPaymentMethod(false) +} +``` + +This function initiates a new payment session for the cart and disables the `isUsingSavedPaymentMethod` state variable. + +Finally, replace the `return` statement of the `StripeCardContainer` component with the following: + +```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeCardReturnHighlights} +return ( + + {selectedPaymentOptionId === paymentProviderId && + (stripeReady ? ( +
+ + {isUsingSavedPaymentMethod && ( + + )} + {!isUsingSavedPaymentMethod && ( + <> + + Enter your card details: + + { + setCardBrand( + e.brand && e.brand.charAt(0).toUpperCase() + e.brand.slice(1) + ) + setError(e.error?.message || null) + setCardComplete(e.complete) + }} + /> + + )} +
+ ) : ( + + ))} +
+) +``` + +You update the `return` statement to: + +- Pass the new `paymentSession` and `cart` props to the `PaymentContainer` component. +- Show the `StripeSavedPaymentMethodsContainer` component before Stripe's card element. +- Add a button that's shown when the customer selects a saved payment method. The button allows the customer to switch back to entering a new payment method. + +The existing Stripe element in checkout will now show the saved payment methods to the customer along with the component to enter a card's details. + +Since you added new props to the `StripeCardContainer` and `PaymentContainer` components, you need to update other components that use them to pass the props. + +In `src/modules/checkout/components/payment/index.tsx`, find usages of `StripeCardContainer` and `PaymentContainer` in the return statement and add the `paymentSession` and `cart` props: + +```tsx title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["5"], ["6"], ["11"], ["12"]]} +
+ {isStripeFunc(paymentMethod.id) ? ( + + ) : ( + + )} +
+``` + +### Support Updating Stripe's Client Secret + +The Next.js Starter Storefront uses Stripe's `Elements` component to wrap the payment elements. The `Elements` component requires a `clientSecret` prop, which is available in the cart's payment session. + +With the recent changes, the client secret will be updated whenever a payment session is initiated, such as when the customer selects a saved payment method. However, the `options.clientSecret` prop of the `Elements` component is immutable, meaning that it cannot be changed after the component is mounted. + +To force the component to re-mount and update the `clientSecret` prop, you can add a `key` prop to the `Elements` component. The `key` prop ensures that the `Elements` component re-mounts whenever the client secret changes, allowing Stripe to process the updated payment session. + +In `src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx`, find the `Elements` component in the `return` statement and add the `key` prop: + +```tsx title="src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["4"]]} + + {children} + +``` + +You set the `key` prop to the client secret, which forces the `Elements` component to re-mount whenever the client secret changes. + +### Support Payment with Saved Payment Method + +The last change you need to make ensures that the customer can place an order with a saved payment method. + +When the customer places the order, and they've chosen Stripe as a payment method, the Next.js Starter Storefront uses Stripe's `confirmCardPayment` method to confirm the payment. This method accepts either the ID of a saved payment method, or the details of a new card. + +So, you need to update the `confirmCardPayment` usage to support passing the ID of the selected payment method if the customer has selected one. + +In `src/modules/checkout/components/payment-button/index.tsx`, find the `handlePayment` method and update its first `if` condition: + +```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" +if (!stripe || !elements || (!card && !session?.data.payment_method_id) || !cart) { + setSubmitting(false) + return +} +``` + +This allows the customer to place their order if they have selected a saved payment method but have not entered a new card. + +Then, find the usage of `confirmCardPayment` in the `handlePayment` function and change it to the following: + +```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={confirmPaymentHighlights} +await stripe +.confirmCardPayment(session?.data.client_secret as string, { + payment_method: session?.data.payment_method_id as string || { + card: card!, + billing_details: { + name: + cart.billing_address?.first_name + + " " + + cart.billing_address?.last_name, + address: { + city: cart.billing_address?.city ?? undefined, + country: cart.billing_address?.country_code ?? undefined, + line1: cart.billing_address?.address_1 ?? undefined, + line2: cart.billing_address?.address_2 ?? undefined, + postal_code: cart.billing_address?.postal_code ?? undefined, + state: cart.billing_address?.province ?? undefined, + }, + email: cart.email, + phone: cart.billing_address?.phone ?? undefined, + }, + }, +}) +.then(({ error, paymentIntent }) => { + if (error) { + const pi = error.payment_intent + + if ( + (pi && pi.status === "requires_capture") || + (pi && pi.status === "succeeded") + ) { + onPaymentCompleted() + } + + setErrorMessage(error.message || null) + return + } + + if ( + (paymentIntent && paymentIntent.status === "requires_capture") || + paymentIntent.status === "succeeded" + ) { + return onPaymentCompleted() + } + + return +}) +``` + +In particular, you're changing the `payment_method` property to either be the ID of the selected payment method, or the details of a new card. This allows the customer to place an order with either a saved payment method or a new one. + +### Test it Out + +You can now test out placing orders with a saved payment method. + +To do that, start the Medusa application by running the following command in the Medusa application's directory: + +```bash npm2yarn +npm run dev +``` + +Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: + +```bash npm2yarn +npm run dev +``` + +In the Next.js Starter Storefront, login with the customer account you created earlier and add a product to the cart. + +Then, proceed to the checkout flow.

However, it delegates the actual payment processing to module providers that integrate third-party payment services. - -The [Stripe Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-provider/stripe/index.html.md) is a Payment Module Provider that integrates Stripe into your Medusa application to process payments. It can also save payment methods securely. - -In this section, you'll set up the Stripe Module Provider in your Medusa application. - -### Prerequisites - -- [Stripe account](https://stripe.com/) -- [Stripe Secret and Public API Keys](https://support.stripe.com/questions/locate-api-keys-in-the-dashboard) - -### Register the Stripe Module Provider - -To register the Stripe Module Provider in your Medusa application, add it to the array of providers passed to the Payment Module in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/payment", - options: { - providers: [ - { - resolve: "@medusajs/medusa/payment-stripe", - id: "stripe", - options: { - apiKey: process.env.STRIPE_API_KEY, - }, - }, - ], - }, - }, - ], -}) -``` - -The Medusa configuration accepts a `modules` array, which contains the modules to be loaded. While the Payment Module is loaded by default, you need to add it again when registering a new provider. - -You register provides in the `providers` option of the Payment Module. Each provider is an object with the following properties: - -- `resolve`: The package name of the provider. -- `id`: The ID of the provider. This is used to identify the provider in the Medusa application. -- `options`: The options to be passed to the provider. In this case, the `apiKey` option is required for the Stripe Module Provider. - -Learn about other options in the [Stripe Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-provider/stripe#module-options/index.html.md) documentation. - -### Add Environment Variables - -Next, add the following environment variables to your `.env` file: - -```plain -STRIPE_API_KEY=sk_... -``` - -Where `STRIPE_API_KEY` is your Stripe Secret API Key. You can find it in the Stripe dashboard under Developers > API keys. - -![Secret API Key in the Stripe dashboard](https://res.cloudinary.com/dza7lstvk/image/upload/v1745313823/Medusa%20Resources/Screenshot_2025-04-22_at_12.20.08_PM_w6rxxo.png) - -### Enable Stripe in a Region - -In Medusa, each [region](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/region/index.html.md) (which is a geographical area where your store operates) can have different payment methods enabled. So, after registering the Stripe Module Provider, you need to enable it in a region. - -To enable it in a region, start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Then, go to `localhost:9000/app` and log in with the user you created earlier. - -Once you're logged in: - -1.

You can find it in the Stripe dashboard under Developers > API keys. - -*** - -## Step 3: List Payment Methods API Route - -The Payment Module uses [account holders](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/account-holder/index.html.md) to represent a customer's details that are stored in a third-party payment provider. Medusa creates an account holder for each customer, allowing you later to retrieve the customer's saved payment methods in the third-party provider. - -![Diagram illustrating the relation between customers and account holders in Medusa, and customers in Stripe](https://res.cloudinary.com/dza7lstvk/image/upload/v1745314344/Medusa%20Resources/customer-account-stripe_in5ei6.jpg) - -While this feature is available out-of-the-box, you need to expose it to clients, like storefronts, by creating 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. - -In this step, you'll create an API route that lists the saved payment methods for an authenticated customer. - -Refer to the [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md) documentation to learn more. - -### Create API Route - -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`, and it can include path parameters using square brackets. - -So, to create an API route at the path `/store/payment-methods/:account-holder-id`, create the file `src/api/store/payment-methods/[account_holder_id]/route.ts` with the following content: - -```ts title="src/api/store/payment-methods/[account_holder_id]/route.ts" highlights={apiRouteHighlights} -import { MedusaError } from "@medusajs/framework/utils" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export async function GET( - req: MedusaRequest, - res: MedusaResponse -) { - const { account_holder_id } = req.params - const query = req.scope.resolve("query") - const paymentModuleService = req.scope.resolve("payment") - - const { data: [accountHolder] } = await query.graph({ - entity: "account_holder", - fields: [ - "data", - "provider_id", - ], - filters: { - id: account_holder_id, - }, - }) - - if (!accountHolder) { - throw new MedusaError( - MedusaError.Types.NOT_FOUND, - "Account holder not found" - ) - } - - const paymentMethods = await paymentModuleService.listPaymentMethods( - { - provider_id: accountHolder.provider_id, - context: { - account_holder: { - data: { - id: accountHolder.data.id, - }, - }, - }, - } - ) - - res.json({ - payment_methods: paymentMethods, - }) -} -``` - -Since you export a route handler function named `GET`, you expose a `GET` API route at `/store/payment-methods/:account-holder-id`. 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. - -The request object has a `scope` property, which is an instance of the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). The Medusa container is a registry of Framework and commerce tools that you can access in the API route. - -You use the Medusa container to resolve: - -- [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules in the Medusa application. -- The [Payment Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/index.html.md)'s service, which provides an interface to manage and process payments with third-party providers. - -You use Query to retrieve the account holder with the ID passed as a path parameter. If the account holder is not found, you throw an error. - -Then, you use the [listPaymentMethods](https://docs.medusajs.com/references/payment/listPaymentMethods/index.html.md) method of the Payment Module's service to retrieve the payment providers saved in the third-party provider. The method accepts an object with the following properties: - -- `provider_id`: The ID of the provider, such as Stripe's ID. The account holder stores the ID its associated provider. -- `context`: The context of the request. In this case, you pass the account holder's ID to retrieve the payment methods associated with it in the third-party provider. - -Finally, you return the payment methods in the response. - -### Protect API Route - -Only authenticated customers can access and use saved payment methods. So, you need to protect the API route to ensure that only authenticated customers can access it. - -To protect an API route, you can add 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. You can add an authentication middleware that ensures that the request is authenticated before executing the route handler function. - -Refer to the [Middlewares](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) documentation to learn more. - -Middlewares are added in the `src/api/middlewares.ts` file. So, create the file with the following content: - -```ts title="src/api/middlewares.ts" -import { authenticate, defineMiddlewares } from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/payment-methods/:provider_id/:account_holder_id", - method: "GET", - middlewares: [ - authenticate("customer", ["bearer", "session"]), - ], - }, - ], -}) -``` - -The `src/api/middlewares.ts` file must use the `defineMiddlewares` function and export its result. The `defineMiddlewares` function accepts a `routes` array that accepts objects with the following properties: - -- `matcher`: The path of the API route to apply the middleware to. -- `method`: The HTTP method of the API route to apply the middleware to. -- `middlewares`: An array of middlewares to apply to the API route. - -You apply the `authenticate` middleware to the API route you created earlier. The `authenticate` middleware ensures that only authenticated customers can access the API route. - -Refer to the [Protected Routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/protected-routes/index.html.md) documentation to learn more about the `authenticate` middleware. - -Your API route can now only be accessed by authenticated customers. You'll test it out as you customize the Next.js Starter Storefront in the next steps. - -*** - -## Step 4: Save Payment Methods During Checkout - -In this step, you'll customize the checkout flow in the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to save payment methods during checkout. - -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-payment`, you can find the storefront by going back to the parent directory and changing to the `medusa-payment-storefront` directory: - -```bash -cd ../medusa-payment-storefront # change based on your project name -``` - -During checkout, when the customer chooses a payment method, such as Stripe, the Next.js Starter Storefront creates a [payment session](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-session/index.html.md) in Medusa using the [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route. - -Under the hood, Medusa uses the associated payment provider (Stripe) to initiate the payment process with the associated third-party payment provider. The [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route accepts a `data` object parameter in the request body that allows you to pass data relevant to the third-party payment provider. - -So, to save the payment method that the customer uses during checkout with Stripe, you must pass the `setup_future_usage` property in the `data` object. The `setup_future_usage` property is a Stripe-specific property that allows you to save the payment method for future use. - -In `src/modules/checkout/components/payment/index.tsx` of the Next.js Starter Storefront, there are two uses of the `initiatePaymentSession` function. Update each of them to pass the `data` property: - -```ts title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" -// update in two places -await initiatePaymentSession(cart, { - // ... - data: { - setup_future_usage: "off_session", - }, -}) -``` - -You customize the `initiatePaymentSession` function to pass the `data` object with the `setup_future_usage` property. You set the value to `off_session` to allow using the payment method outside of the checkout flow, such as for follow up payments. You can use `on_session` instead if you only want the payment method to be used by the customer during checkout. - -By making this change, you always save the payment method that the customer uses during checkout. You can alternatively show a checkbox to confirm saving the payment method, and only pass the `data` object if the customer checks it. - -### Test it Out - -To test it out, start the Medusa application by running the following command in the Medusa application's directory: - -```bash npm2yarn -npm run dev -``` - -Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: - -```bash npm2yarn -npm run dev -``` - -You can open the storefront in your browser at `localhost:8000`. Then, create a new customer account by clicking on the "Account" link at the top right. - -After creating an account and logging in, add a product to the cart and go to the checkout page. Once you get to the payment step, choose Stripe and enter a [test card number](https://docs.stripe.com/testing#cards), such as `4242 4242 4242 4242`. - -Then, place the order. Once the order is placed, you can check on the Stripe dashboard that the payment method was saved by: - -1. Going to the "Customers" section in the Stripe dashboard. -2. Clicking on the customer you just placed the order with. -3. Scrolling down to the "Payment methods" section. You'll find the payment method you just used to place the order. - -![Saved payment method on the Stripe dashboard](https://res.cloudinary.com/dza7lstvk/image/upload/v1745249064/Medusa%20Resources/Screenshot_2025-04-21_at_6.24.00_PM_peotrd.png) - -In the next step, you'll show the saved payment methods to the customer during checkout and allow them to select one of them. - -*** - -## Step 5: Use Saved Payment Methods During Checkout - -In this step, you'll customize the checkout flow in the Next.js Starter Storefront to show the saved payment methods to the customer and allow them to select one of them to place the order. - -### Retrieve Saved Payment Methods - -To retrieve the saved payment methods, you'll add a server function that retrieves the customer's saved payment methods from the API route you created earlier. - -Add the following in `src/lib/data/payment.ts`: - -```ts title="src/lib/data/payment.ts" badgeLabel="Storefront" badgeColor="blue" highlights={paymentHighlights} -export type SavedPaymentMethod = { - id: string - provider_id: string - data: { - card: { - brand: string - last4: string - exp_month: number - exp_year: number - } - } -} - -export const getSavedPaymentMethods = async (accountHolderId: string) => { - const headers = { - ...(await getAuthHeaders()), - } - - return sdk.client.fetch<{ - payment_methods: SavedPaymentMethod[] - }>( - `/store/payment-methods/${accountHolderId}`, - { - method: "GET", - headers, - } - ).catch(() => { - return { - payment_methods: [], - } - }) -} -``` - -You define a type for the retrieved payment methods. It contains the following properties: - -- `id`: The ID of the payment method in the third-party provider. -- `provider_id`: The ID of the provider in the Medusa application, such as Stripe's ID. -- `data`: Additional data retrieved from the third-party provider related to the saved payment method. The type is modeled after the data returned by Stripe, but you can change it to match other payment providers. - -You also create a `getSavedPaymentMethods` function that retrieves the saved payment methods from the API route you created earlier. The function accepts the account holder ID as a parameter and returns the saved payment methods. - -### Add Saved Payment Methods Component - -Next, you'll add the component that shows the saved payment methods and allows the customer to select one of them. - -The component that shows the Stripe card element is defined in `src/modules/checkout/components/payment-container/index.tsx`. So, you'll define the component for the saved payment methods in the same file. - -Start by adding the following import statements at the top of the file: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import { Button } from "@medusajs/ui" -import { useEffect, useState } from "react" -import { HttpTypes } from "@medusajs/types" -import { SavedPaymentMethod, getSavedPaymentMethods } from "@lib/data/payment" -import { initiatePaymentSession } from "../../../../lib/data/cart" -import { capitalize } from "lodash" -``` - -Then, update the `PaymentContainerProps` type to include the payment session and cart details: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -type PaymentContainerProps = { - // ... - paymentSession?: HttpTypes.StorePaymentSession - cart: HttpTypes.StoreCart -} -``` - -You'll need these details to find which saved payment method the customer selected, and to initiate a new payment session for the cart when the customer chooses a saved payment method. - -Next, add the following component at the end of the file: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeSavedPaymentMethodsHighlights} -const StripeSavedPaymentMethodsContainer = ({ - paymentSession, - setCardComplete, - setCardBrand, - setError, - cart, -}: { - paymentSession?: HttpTypes.StorePaymentSession - setCardComplete: (complete: boolean) => void - setCardBrand: (brand: string) => void - setError: (error: string | null) => void - cart: HttpTypes.StoreCart -}) => { - const [savedPaymentMethods, setSavedPaymentMethods] = useState< - SavedPaymentMethod[] - >([]) - const [selectedPaymentMethod, setSelectedPaymentMethod] = useState< - string | undefined - >( - paymentSession?.data?.payment_method_id as string | undefined - ) - - useEffect(() => { - const accountHolderId = ( - paymentSession?.context?.account_holder as Record - ) - ?.id - - if (!accountHolderId) { - return - } - - getSavedPaymentMethods(accountHolderId) - .then(({ payment_methods }) => { - setSavedPaymentMethods(payment_methods) - }) - }, [paymentSession]) - - useEffect(() => { - if (!selectedPaymentMethod || !savedPaymentMethods.length) { - setCardComplete(false) - setCardBrand("") - setError(null) - return - } - const selectedMethod = savedPaymentMethods.find( - (method) => method.id === selectedPaymentMethod - ) - - if (!selectedMethod) { - return - } - - setCardBrand(capitalize(selectedMethod.data.card.brand)) - setCardComplete(true) - setError(null) - }, [selectedPaymentMethod, savedPaymentMethods]) - - const handleSelect = async (method: SavedPaymentMethod) => { - // initiate a new payment session with the selected payment method - await initiatePaymentSession(cart, { - provider_id: method.provider_id, - data: { - payment_method_id: method.id, - }, - }).catch((error) => { - setError(error.message) - }) - - setSelectedPaymentMethod(method.id) - } - - if (!savedPaymentMethods.length) { - return <> - } - - // TODO add return statement -} -``` - -You define a `StripeSavedPaymentMethodsContainer` component that accepts the following props: - -- `paymentSession`: The cart's current payment session. -- `setCardComplete`: A function to tell parent components whether the cart or payment method selection is complete. This allows the customer to proceed to the next step in the checkout flow. -- `setCardBrand`: A function to set the brand of the selected payment method. This is useful to show the brand of the selected payment method in review sections of the checkout flow. -- `setError`: A function to set the error message in case of an error. -- `cart`: The cart's details. - -In the component, you define a state variable to store the saved payment methods and another one to store the selected payment method. - -Then, you use the `useEffect` hook to retrieve the saved payment methods for the account holder set in the cart's payment session. You use the `getSavedPaymentMethods` function you created earlier to retrieve the saved payment methods. - -You also use another `useEffect` hook that is executed when the selected payment method changes. In this hook, you check if the selected payment method is valid and set the card brand and completion status accordingly. - -Finally, you define a `handleSelect` function that you'll execute when the customer selects a saved payment method. It creates a new payment session with the selected payment method. - -To show the saved payment methods, replace the `TODO` with the following `return` statement: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -
- - Choose a saved payment method: - - {savedPaymentMethods.map((method) => ( -
handleSelect(method)} - > -
- { - if (e.target.checked) { - handleSelect(method) - } - }} - /> -
- - {capitalize(method.data.card.brand)} •••• {method.data.card.last4} - - - Expires {method.data.card.exp_month}/{method.data.card.exp_year} - -
-
-
- ))} -
-) -``` - -You display the saved payment methods as radio buttons. When the customer selects one of them, you execute the `handleSelect` function to initiate a new payment session with the selected payment method. - -### Modify Existing Stripe Element - -Now that you have the component to show the saved payment methods, you need to modify the existing Stripe element to allow customers to select an existing payment method or enter a new one. - -In the same `src/modules/checkout/components/payment-container/index.tsx` file, expand the new `paymentSession` and `cart` props of the `StripeCardContainer` component: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -export const StripeCardContainer = ({ - // ... - paymentSession, - cart, -}: Omit & { - // ... -}) => { - // ... -} -``` - -Then, add a new state variable that keeps track of whether the customer is using a saved payment method or entering a new one: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const [isUsingSavedPaymentMethod, setIsUsingSavedPaymentMethod] = useState( - paymentSession?.data?.payment_method_id !== undefined -) -``` - -Next, add a function that resets the payment session when the customer switches between saved and new payment methods: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const handleRefreshSession = async () => { - await initiatePaymentSession(cart, { - provider_id: paymentProviderId, - }) - setIsUsingSavedPaymentMethod(false) -} -``` - -This function initiates a new payment session for the cart and disables the `isUsingSavedPaymentMethod` state variable. - -Finally, replace the `return` statement of the `StripeCardContainer` component with the following: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeCardReturnHighlights} -return ( - - {selectedPaymentOptionId === paymentProviderId && - (stripeReady ? ( -
- - {isUsingSavedPaymentMethod && ( - - )} - {!isUsingSavedPaymentMethod && ( - <> - - Enter your card details: - - { - setCardBrand( - e.brand && e.brand.charAt(0).toUpperCase() + e.brand.slice(1) - ) - setError(e.error?.message || null) - setCardComplete(e.complete) - }} - /> - - )} -
- ) : ( - - ))} -
-) -``` - -You update the `return` statement to: - -- Pass the new `paymentSession` and `cart` props to the `PaymentContainer` component. -- Show the `StripeSavedPaymentMethodsContainer` component before Stripe's card element. -- Add a button that's shown when the customer selects a saved payment method. The button allows the customer to switch back to entering a new payment method. - -The existing Stripe element in checkout will now show the saved payment methods to the customer along with the component to enter a card's details. - -Since you added new props to the `StripeCardContainer` and `PaymentContainer` components, you need to update other components that use them to pass the props. - -In `src/modules/checkout/components/payment/index.tsx`, find usages of `StripeCardContainer` and `PaymentContainer` in the return statement and add the `paymentSession` and `cart` props: - -```tsx title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["5"], ["6"], ["11"], ["12"]]} -
- {isStripeFunc(paymentMethod.id) ? ( - - ) : ( - - )} -
-``` - -### Support Updating Stripe's Client Secret - -The Next.js Starter Storefront uses Stripe's `Elements` component to wrap the payment elements. The `Elements` component requires a `clientSecret` prop, which is available in the cart's payment session. - -With the recent changes, the client secret will be updated whenever a payment session is initiated, such as when the customer selects a saved payment method. However, the `options.clientSecret` prop of the `Elements` component is immutable, meaning that it cannot be changed after the component is mounted. - -To force the component to re-mount and update the `clientSecret` prop, you can add a `key` prop to the `Elements` component. The `key` prop ensures that the `Elements` component re-mounts whenever the client secret changes, allowing Stripe to process the updated payment session. - -In `src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx`, find the `Elements` component in the `return` statement and add the `key` prop: - -```tsx title="src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["4"]]} - - {children} - -``` - -You set the `key` prop to the client secret, which forces the `Elements` component to re-mount whenever the client secret changes. - -### Support Payment with Saved Payment Method - -The last change you need to make ensures that the customer can place an order with a saved payment method. - -When the customer places the order, and they've chosen Stripe as a payment method, the Next.js Starter Storefront uses Stripe's `confirmCardPayment` method to confirm the payment. This method accepts either the ID of a saved payment method, or the details of a new card. - -So, you need to update the `confirmCardPayment` usage to support passing the ID of the selected payment method if the customer has selected one. - -In `src/modules/checkout/components/payment-button/index.tsx`, find the `handlePayment` method and update its first `if` condition: - -```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" -if (!stripe || !elements || (!card && !session?.data.payment_method_id) || !cart) { - setSubmitting(false) - return -} -``` - -This allows the customer to place their order if they have selected a saved payment method but have not entered a new card. - -Then, find the usage of `confirmCardPayment` in the `handlePayment` function and change it to the following: - -```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={confirmPaymentHighlights} -await stripe -.confirmCardPayment(session?.data.client_secret as string, { - payment_method: session?.data.payment_method_id as string || { - card: card!, - billing_details: { - name: - cart.billing_address?.first_name + - " " + - cart.billing_address?.last_name, - address: { - city: cart.billing_address?.city ?? undefined, - country: cart.billing_address?.country_code ?? undefined, - line1: cart.billing_address?.address_1 ?? undefined, - line2: cart.billing_address?.address_2 ?? undefined, - postal_code: cart.billing_address?.postal_code ?? undefined, - state: cart.billing_address?.province ?? undefined, - }, - email: cart.email, - phone: cart.billing_address?.phone ?? undefined, - }, - }, -}) -.then(({ error, paymentIntent }) => { - if (error) { - const pi = error.payment_intent - - if ( - (pi && pi.status === "requires_capture") || - (pi && pi.status === "succeeded") - ) { - onPaymentCompleted() - } - - setErrorMessage(error.message || null) - return - } - - if ( - (paymentIntent && paymentIntent.status === "requires_capture") || - paymentIntent.status === "succeeded" - ) { - return onPaymentCompleted() - } - - return -}) -``` - -In particular, you're changing the `payment_method` property to either be the ID of the selected payment method, or the details of a new card. This allows the customer to place an order with either a saved payment method or a new one. - -### Test it Out - -You can now test out placing orders with a saved payment method. - -To do that, start the Medusa application by running the following command in the Medusa application's directory: - -```bash npm2yarn -npm run dev -``` - -Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: - -```bash npm2yarn -npm run dev -``` - -In the Next.js Starter Storefront, login with the customer account you created earlier and add a product to the cart. - -Then, proceed to the checkout flow. In the payment step, you should see the saved payment method you used earlier. You can select it and place the order. - -![Saved payment method in checkout](https://res.cloudinary.com/dza7lstvk/image/upload/v1745308047/Medusa%20Resources/Screenshot_2025-04-21_at_4.07.34_PM_krudjq.png) - -Once the order is placed successfully, you can check it in the Medusa Admin dashboard.

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 in this case is `undefined`. +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/algolia-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.

As a second parameter, it accepts the module's options. + +### Add Authentication Logic + +To authenticate with the Magento server, you'll add a method to the service that retrieves an access token from Magento using the username and password in the options. This access token is used in subsequent requests to the Magento server. + +First, add the following property to the `MagentoModuleService` class: + +```ts title="src/modules/magento/service.ts" +export default class MagentoModuleService { + private accessToken: { + token: string + expiresAt: Date + } + // ... +} +``` + +You add an `accessToken` property to store the access token and its expiration date. The access token Magento returns expires after four hours, so you store the expiration date to know when to refresh the token. + +Next, add the following `authenticate` method to the `MagentoModuleService` class: + +```ts title="src/modules/magento/service.ts" +import { MedusaError } from "@medusajs/framework/utils" + +export default class MagentoModuleService { + // ... + async authenticate() { + const response = await fetch(`${this.options.baseUrl}/rest/${this.options.storeCode}/V1/integration/admin/token`, { + method: "POST", + headers: { + "Content-Type": "application/json", + }, + body: JSON.stringify({ username: this.options.username, password: this.options.password }), }) + + const token = await response.text() + + if (!response.ok) { + throw new MedusaError(MedusaError.Types.UNAUTHORIZED, `Failed to authenticate with Magento: ${token}`) + } + + this.accessToken = { + token: token.replaceAll("\"", ""), + expiresAt: new Date(Date.now() + 4 * 60 * 60 * 1000), // 4 hours in milliseconds + } } } ``` -You define two methods: +You create an `authenticate` method that sends a POST request to the Magento server's `/rest/{storeCode}/V1/integration/admin/token` endpoint, passing the username and password in the request body. -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. +If the request is successful, you store the access token and its expiration date in the `accessToken` property. If the request fails, you throw a `MedusaError` with the error message returned by Magento. -#### Retrieve and Delete Methods +Lastly, add an `isAccessTokenExpired` method that checks if the access token has expired: -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/magento/service.ts" +export default class MagentoModuleService { // ... - - 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, - }) + async isAccessTokenExpired(): Promise { + return !this.accessToken || this.accessToken.expiresAt < new Date() } } ``` -You define two methods: +In the `isAccessTokenExpired` method, you return a boolean indicating whether the access token has expired. You'll use this in later methods to check if you need to refresh the access token. -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. +### Retrieve Products from Magento -#### Search Method +Next, you'll add a method that retrieves products from Magento. Due to limitations in Magento's API that makes it difficult to differentiate between simple products that don't belong to a configurable product and those that do, you'll only retrieve configurable products and their children. You'll also retrieve the configurable attributes of the product, such as color and size. -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. +First, you'll add some types to represent a Magento product and its attributes. Create the file `src/modules/magento/types.ts` in the plugin with the following content: -Add the following method to the `AlgoliaModuleService` class: +![Diagram showcasing the types file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739346287/Medusa%20Resources/magento-3_fpghog.jpg) -```ts title="src/modules/algolia/service.ts" -export default class AlgoliaModuleService { +```ts title="src/modules/magento/types.ts" +export type MagentoProduct = { + id: number + sku: string + name: string + price: number + status: number + // not handling other types + type_id: "simple" | "configurable" + created_at: string + updated_at: string + extension_attributes: { + category_links: { + category_id: string + }[] + configurable_product_links?: number[] + configurable_product_options?: { + id: number + attribute_id: string + label: string + position: number + values: { + value_index: number + }[] + }[] + } + media_gallery_entries: { + id: number + media_type: string + label: string + position: number + disabled: boolean + types: string[] + file: string + }[] + custom_attributes: { + attribute_code: string + value: string + }[] + // added by module + children?: MagentoProduct[] +} + +export type MagentoAttribute = { + attribute_code: string + attribute_id: number + default_frontend_label: string + options: { + label: string + value: string + }[] +} + +export type MagentoPagination = { + search_criteria: { + filter_groups: [], + page_size: number + current_page: number + } + total_count: number +} + +export type MagentoPaginatedResponse = { + items: TData[] +} & MagentoPagination +``` + +You define the following types: + +- `MagentoProduct`: Represents a product in Magento. +- `MagentoAttribute`: Represents an attribute in Magento. +- `MagentoPagination`: Represents the pagination information returned by Magento's API. +- `MagentoPaginatedResponse`: Represents a paginated response from Magento's API for a specific item type, such as products. + +Next, add the `getProducts` method to the `MagentoModuleService` class: + +```ts title="src/modules/magento/service.ts" +export default class MagentoModuleService { // ... + async getProducts(options?: { + currentPage?: number + pageSize?: number + }): Promise<{ + products: MagentoProduct[] + attributes: MagentoAttribute[] + pagination: MagentoPagination + }> { + const { currentPage = 1, pageSize = 100 } = options || {} + const getAccessToken = await this.isAccessTokenExpired() + if (getAccessToken) { + await this.authenticate() + } - async search(query: string, type: AlgoliaIndexType = "product") { - const indexName = await this.getIndexName(type) - return await this.client.search({ - requests: [ - { - indexName, - query, + // TODO prepare query params + } +} +``` + +The `getProducts` method receives an optional `options` object with the `currentPage` and `pageSize` properties. So far, you check if the access token has expired and, if so, retrieve a new one using the `authenticate` method. + +Next, you'll prepare the query parameters to pass in the request that retrieves products. Replace the `TODO` with the following: + +```ts title="src/modules/magento/service.ts" +const searchQuery = new URLSearchParams() +// pass pagination parameters +searchQuery.append( + "searchCriteria[currentPage]", + currentPage?.toString() || "1" +) +searchQuery.append( + "searchCriteria[pageSize]", + pageSize?.toString() || "100" +) + +// retrieve only configurable products +searchQuery.append( + "searchCriteria[filter_groups][1][filters][0][field]", + "type_id" +) +searchQuery.append( + "searchCriteria[filter_groups][1][filters][0][value]", + "configurable" +) +searchQuery.append( + "searchCriteria[filter_groups][1][filters][0][condition_type]", + "in" +) + +// TODO send request to retrieve products +``` + +You create a `searchQuery` object to store the query parameters to pass in the request. Then, you add the pagination parameters and the filter to retrieve only configurable products. + +Next, you'll send the request to retrieve products from Magento. Replace the `TODO` with the following: + +```ts title="src/modules/magento/service.ts" +const { items: products, ...pagination }: MagentoPaginatedResponse = await fetch( + `${this.options.baseUrl}/rest/${this.options.storeCode}/V1/products?${searchQuery}`, + { + headers: { + "Authorization": `Bearer ${this.accessToken.token}`, + }, + } +).then((res) => res.json()) +.catch((err) => { + console.log(err) + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `Failed to get products from Magento: ${err.message}` + ) +}) + +// TODO prepare products +``` + +You send a `GET` request to the Magento server's `/rest/{storeCode}/V1/products` endpoint, passing the query parameters in the URL. You also pass the access token in the `Authorization` header. + +Next, you'll prepare the retrieved products by retrieving their children, configurable attributes, and modifying their image URLs. Replace the `TODO` with the following: + +```ts title="src/modules/magento/service.ts" +const attributeIds: string[] = [] + +await promiseAll( + products.map(async (product) => { + // retrieve its children + product.children = await fetch( + `${this.options.baseUrl}/rest/${this.options.storeCode}/V1/configurable-products/${product.sku}/children`, + { + headers: { + "Authorization": `Bearer ${this.accessToken.token}`, }, - ], + } + ).then((res) => res.json()) + .catch((err) => { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `Failed to get product children from Magento: ${err.message}` + ) }) + + product.media_gallery_entries = product.media_gallery_entries.map( + (entry) => ({ + ...entry, + file: `${this.options.migrationOptions?.imageBaseUrl}${entry.file}`, + } + )) + + attributeIds.push(...( + product.extension_attributes.configurable_product_options?.map( + (option) => option.attribute_id) || [] + ) + ) + }) +) + +// TODO retrieve attributes +``` + +You loop over the retrieved products and retrieve their children using the `/rest/{storeCode}/V1/configurable-products/{sku}/children` endpoint. You also modify the image URLs to use the base URL in the migration options, if provided. + +In addition, you store the IDs of the configurable products' attributes in the `attributeIds` array. You'll add a method that retrieves these attributes. + +Add the new method `getAttributes` to the `MagentoModuleService` class: + +```ts title="src/modules/magento/service.ts" +export default class MagentoModuleService { + // ... + async getAttributes({ + ids, + }: { + ids: string[] + }): Promise { + const getAccessToken = await this.isAccessTokenExpired() + if (getAccessToken) { + await this.authenticate() + } + + // filter by attribute IDs + const searchQuery = new URLSearchParams() + searchQuery.append( + "searchCriteria[filter_groups][0][filters][0][field]", + "attribute_id" + ) + searchQuery.append( + "searchCriteria[filter_groups][0][filters][0][value]", + ids.join(",") + ) + searchQuery.append( + "searchCriteria[filter_groups][0][filters][0][condition_type]", + "in" + ) + + const { + items: attributes, + }: MagentoPaginatedResponse = await fetch( + `${this.options.baseUrl}/rest/${this.options.storeCode}/V1/products/attributes?${searchQuery}`, + { + headers: { + "Authorization": `Bearer ${this.accessToken.token}`, + }, + } + ).then((res) => res.json()) + .catch((err) => { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `Failed to get attributes from Magento: ${err.message}` + ) + }) + + return attributes } } ``` -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 `getAttributes` method receives an object with the `ids` property, which is an array of attribute IDs. You check if the access token has expired and, if so, retrieve a new one using the `authenticate` method. + +Next, you prepare the query parameters to pass in the request to retrieve attributes. You send a `GET` request to the Magento server's `/rest/{storeCode}/V1/products/attributes` endpoint, passing the query parameters in the URL. You also pass the access token in the `Authorization` header. + +Finally, you return the retrieved attributes. + +Now, go back to the `getProducts` method and replace the `TODO` with the following: + +```ts title="src/modules/magento/service.ts" +const attributes = await this.getAttributes({ ids: attributeIds }) + +return { products, attributes, pagination } +``` + +You retrieve the configurable products' attributes using the `getAttributes` method and return the products, attributes, and pagination information. + +You'll use this method in a later step to retrieve products from Magento. ### 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: +So, create the file `src/modules/magento/index.ts` with the following content: -```ts title="src/modules/algolia/index.ts" +![Diagram showcasing the module definition file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739348316/Medusa%20Resources/magento-4_bmepvh.jpg) + +```ts title="src/modules/magento/index.ts" import { Module } from "@medusajs/framework/utils" -import AlgoliaModuleService from "./service" +import MagentoModuleService from "./service" -export const ALGOLIA_MODULE = "algolia" +export const MAGENTO_MODULE = "magento" -export default Module(ALGOLIA_MODULE, { - service: AlgoliaModuleService, +export default Module(MAGENTO_MODULE, { + service: MagentoModuleService, }) ``` 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`. +1. The module's name, which is `magento`. 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. +You'll later use the module's service to retrieve products from Magento. -### Add Module to Medusa's Configurations +### Pass Options to Plugin -Once you finish building the module, add it to Medusa's configurations to start using it. +As mentioned earlier when you registered the plugin in the Medusa Application's `medusa-config.ts` file, you can pass options to the plugin. These options are then passed to the modules in the plugin. -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: +So, add the following options to the plugin's registration in the `medusa-config.ts` file of the Medusa application: ```ts title="medusa-config.ts" module.exports = defineConfig({ // ... - modules: [ + plugins: [ { - resolve: "./src/modules/algolia", + resolve: "medusa-plugin-magento", options: { - appId: process.env.ALGOLIA_APP_ID!, - apiKey: process.env.ALGOLIA_API_KEY!, - productIndexName: process.env.ALGOLIA_PRODUCT_INDEX_NAME!, + baseUrl: process.env.MAGENTO_BASE_URL, + username: process.env.MAGENTO_USERNAME, + password: process.env.MAGENTO_PASSWORD, + migrationOptions: { + imageBaseUrl: process.env.MAGENTO_IMAGE_BASE_URL, + }, }, }, ], }) ``` -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 pass the options that you defined in the `MagentoModuleService`. Make sure to also set their environment variables in the `.env` file: -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 +```bash +MAGENTO_BASE_URL=https://magento.example.com +MAGENTO_USERNAME=admin +MAGENTO_PASSWORD=password +MAGENTO_IMAGE_BASE_URL=https://magento.example.com/pub/media/catalog/product ``` 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. +- `MAGENTO_BASE_URL`: The base URL of the Magento server. It can also be a local URL, such as `http://localhost:8080`. +- `MAGENTO_USERNAME`: The username of a Magento admin user to authenticate with the Magento server. +- `MAGENTO_PASSWORD`: The password of the Magento admin user. +- `MAGENTO_IMAGE_BASE_URL`: The base URL to use for product images. Magento stores product images in the `pub/media/catalog/product` directory, so you can reference them directly or use a CDN URL. If the URLs of product images in the Medusa server already have a different base URL, you can omit this option. -![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) +Medusa supports integrating third-party services, such as [S3](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/file/s3/index.html.md), in a File Module Provider.

You'll see how to use it in the next steps. +You can now use the Magento Module to migrate data, which you'll do in the next steps. *** -## Step 3: Sync Products to Algolia Workflow +## Step 5: Build Product Migration 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. +In this section, you'll add the feature to migrate products from Magento to Medusa. To implement this feature, you'll use a workflow. -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. +A workflow is a series of queries and actions, called steps, that complete a task.

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. +Next, you'll retrieve products that were previously migrated from Magento to determine which products to create or update. Replace the `TODO` with the following: -### Create Products Sync Subscriber +```ts title="src/workflows/migrate-products-from-magento.ts" +const externalIdFilters = transform({ + products, +}, (data) => { + return data.products.map((product) => product.id.toString()) +}) -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. +const { data: existingProducts } = useQueryGraphStep({ + entity: "product", + fields: ["id", "external_id", "variants.id", "variants.metadata"], + filters: { + external_id: externalIdFilters, + }, +}).config({ name: "get-existing-products" }) -Learn more about subscribers in the [Events and Subscribers documentation](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). +// TODO prepare products to create or update +``` -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/algolia-sync.ts` with the following content: +Since the Medusa application creates an internal representation of the workflow's constructor function, you can't manipulate data directly, as variables have no value while creating the internal representation. -```ts title="src/subscribers/algolia-sync.ts" -import { - SubscriberArgs, - type SubscriberConfig, -} from "@medusajs/framework" -import { syncProductsWorkflow } from "../workflows/sync-products" +Refer to the [Workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md) documentation to learn more about the workflow constructor function's constraints. -export default async function algoliaSyncHandler({ - container, -}: SubscriberArgs) { - const logger = container.resolve("logger") - - let hasMore = true - let offset = 0 - const limit = 50 - let totalIndexed = 0 +Instead, you can manipulate data in a workflow's constructor function using `transform` from the Workflows SDK. `transform` is a function that accepts two parameters: - logger.info("Starting product indexing...") +- The data to transform, which in this case is the Magento products. +- A function that transforms the data. The function receives the data passed in the first parameter and returns the transformed data. - while (hasMore) { - const { result: { products, metadata } } = await syncProductsWorkflow(container) - .run({ - input: { - limit, - offset, - }, +In the transformation function, you return the IDs of the Magento products. Then, you use the `useQueryGraphStep` to retrieve products in the Medusa application that have an `external_id` property matching the IDs of the Magento products. You'll use this property to store the IDs of the products in Magento. + +Next, you'll prepare the data to create and update the products. Replace the `TODO` in the workflow function with the following: + +```ts title="src/workflows/migrate-products-from-magento.ts" highlights={prepareHighlights} +const { + productsToCreate, + productsToUpdate, +} = transform({ + products, + attributes, + stores, + shippingProfiles, + existingProducts, +}, (data) => { + const productsToCreate = new Map() + const productsToUpdate = new Map() + + data.products.forEach((magentoProduct) => { + const productData: CreateProductWorkflowInputDTO | UpsertProductDTO = { + title: magentoProduct.name, + description: magentoProduct.custom_attributes.find( + (attr) => attr.attribute_code === "description" + )?.value, + status: magentoProduct.status === 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: "", - }, - ], + title: child.name, + sku: child.sku, + options: childOptions, + prices: data.stores[0].supported_currencies.map(({ currency_code }) => { + return { + amount: child.price, + currency_code, + } + }), + metadata: { + external_id: variantExternalId, + }, + id: existingVariant?.id, } - } - - return await sdk.client.fetch(`/store/products/search`, { - method: "POST", - body: { - query, - }, }) + + productData.images = magentoProduct.media_gallery_entries.filter((entry) => !entry.types.includes("thumbnail")).map((entry) => { + return { + url: entry.file, + metadata: { + external_id: entry.id.toString(), + }, + } + }) + + if (productData.id) { + productsToUpdate.set(existingProduct.id, productData) + } else { + productsToCreate.set(productData.external_id!, productData) + } + }) + + return { + productsToCreate: Array.from(productsToCreate.values()), + productsToUpdate: Array.from(productsToUpdate.values()), + } +}) + +// TODO create and update products +``` + +You use `transform` again to prepare the data to create and update the products in the Medusa application. For each Magento product, you map its equivalent Medusa product's data: + +- You set the product's general details, such as the title, description, status, handle, external ID, and thumbnail using the Magento product's data and custom attributes. +- You associate the product with the default sales channel and shipping profile retrieved previously. +- You map the Magento product's configurable product options to Medusa product options. In Medusa, a product's option has a label, such as "Color", and values, such as "Red". To map the option values, you use the attributes retrieved from Magento. +- You map the Magento product's children to Medusa product variants. For the variant options, you pass an object whose keys is the option's label, such as "Color", and values is the option's value, such as "Red". For the prices, you set the variant's price based on the Magento child's price for every supported currency in the Medusa store. Also, you set the Magento child product's ID in the Medusa variant's `metadata.external_id` property. +- You map the Magento product's media gallery entries to Medusa product images. You filter out the thumbnail image and set the URL and the Magento image's ID in the Medusa image's `metadata.external_id` property. + +In addition, you use the existing products retrieved in the previous step to determine whether a product should be created or updated. If there's an existing product whose `external_id` matches the ID of the magento product, you set the existing product's ID in the `id` property of the product to be updated. You also do the same for its variants. + +Finally, you return the products to create and update. + +The last steps of the workflow is to create and update the products. Replace the `TODO` in the workflow function with the following: + +```ts title="src/workflows/migrate-products-from-magento.ts" +createProductsWorkflow.runAsStep({ + input: { + products: productsToCreate, }, +}) + +updateProductsWorkflow.runAsStep({ + input: { + products: productsToUpdate, + }, +}) + +return new WorkflowResponse(pagination) +``` + +You use the `createProductsWorkflow` and `updateProductsWorkflow` workflows from Medusa's `@medusajs/medusa/core-flows` package to create and update the products in the Medusa application. + +Workflows must return an instance of `WorkflowResponse`, passing as a parameter the data to return to the workflow's executor. This workflow returns the pagination parameters, allowing you to paginate the product migration process. + +You can now use this workflow to migrate products from Magento to Medusa. You'll learn how to use it in the next steps. + +*** + +## Step 6: Schedule Product Migration + +There are many ways to execute tasks asynchronously in Medusa, such as [scheduling a job](https://docs.medusajs.com/docs/learn/fundamentals/scheduled-jobs/index.html.md) or [handling emitted events](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). + +In this guide, you'll learn how to schedule the product migration at a specified interval using a scheduled job. A scheduled job is an asynchronous function that the Medusa application runs at the interval you specify during the Medusa application's runtime. + +Refer to the [Scheduled Jobs](https://docs.medusajs.com/docs/learn/fundamentals/scheduled-jobs/index.html.md) documentation to learn more about scheduled jobs. + +To create a scheduled job, in your plugin, create the file `src/jobs/migrate-magento.ts` with the following content: + +![Diagram showcasing the migrate-magento file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739358924/Medusa%20Resources/magento-7_rqoodo.jpg) + +```ts title="src/jobs/migrate-magento.ts" +import { MedusaContainer } from "@medusajs/framework/types" +import { migrateProductsFromMagentoWorkflow } from "../workflows" + +export default async function migrateMagentoJob( + container: MedusaContainer +) { + const logger = container.resolve("logger") + logger.info("Migrating products from Magento...") + + let currentPage = 0 + const pageSize = 100 + let totalCount = 0 + + do { + currentPage++ + + const { + result: pagination, + } = await migrateProductsFromMagentoWorkflow(container).run({ + input: { + currentPage, + pageSize, + }, + }) + + totalCount = pagination.total_count + } while (currentPage * pageSize < totalCount) + + logger.info("Finished migrating products from Magento") +} + +export const config = { + name: "migrate-magento-job", + schedule: "0 0 * * *", } ``` -In the code above, you create a `searchClient` object that initializes the Algolia client with your Algolia App ID and API Key. +A scheduled job file must export: -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. +- An asynchronous function that executes the job's logic. The function receives the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md) as a parameter. +- An object with the job's configuration, including the name and the schedule. The schedule is a cron job pattern as a string. -### Set Environment Variables +In the job function, you resolve the [logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) from the container to log messages. Then, you paginate the product migration process by running the `migrateProductsFromMagentoWorkflow` workflow at each page until you've migrated all products. You use the pagination result returned by the workflow to determine whether there are more products to migrate. -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 ( - <> -

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. +Based on the job's configurations, the Medusa application will run the job at midnight every day. ### Test it Out -To test out the storefront changes and the search API route, start the Medusa application: +To test out this scheduled job, first, change the configuration to run the job every minute: + +```ts title="src/jobs/migrate-magento.ts" +export const config = { + // ... + schedule: "* * * * *", +} +``` + +Then, make sure to run the `plugin:develop` command in the plugin if you haven't already: + +```bash +npx medusa plugin:develop +``` + +This ensures that the plugin's latest changes are reflected in the Medusa application. + +Finally, start the Medusa application that the plugin is installed in: ```bash npm2yarn npm run dev ``` -Then, start the Next.js Starter Storefront from its directory: +After a minute, you'll see a message in the terminal indicating that the migration started: -```bash npm2yarn -npm run dev +```plain title="Terminal" +info: Migrating products from Magento... ``` -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. +Once the migration is done, you'll see the following message: -![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) +```plain title="Terminal" +info: Finished migrating products from Magento +``` + +To confirm that the products were migrated, open the Medusa Admin dashboard at `http://localhost:9000/app` and log in.

A module is a re-usable 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. - -Medusa's Fulfillment Module delegates processing fulfillments and shipments to other modules, called module providers. In this step, you'll create a ShipStation Module Provider that implements all functionalities required for fulfillment. In later steps, you'll add into Medusa shipping options for ShipStation, and allow customers to choose it during checkout. - -Learn more about modules in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). - -### Create Module Directory - -A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/shipstation`. - -![The directory structure of the Medusa application after adding the module's directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1734338950/Medusa%20Resources/shipstation-dir-overview-1_dlsrbv.jpg) - -### 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 ShipStation Module Provider's service and the methods necessary to handle fulfillment. - -Start by creating the file `src/modules/shipstation/service.ts` with the following content: - -![The directory structure of the Medusa application after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339042/Medusa%20Resources/shipstation-dir-overview-2_cmgvcj.jpg) - -```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights1} -import { AbstractFulfillmentProviderService } from "@medusajs/framework/utils" - -export type ShipStationOptions = { - api_key: string -} - -class ShipStationProviderService extends AbstractFulfillmentProviderService { - static identifier = "shipstation" - protected options_: ShipStationOptions - - constructor({}, options: ShipStationOptions) { - super() - - this.options_ = options - } - - // TODO add methods -} - -export default ShipStationProviderService -``` - -A Fulfillment Module Provider service must extend the `AbstractFulfillmentProviderService` class. You'll implement the abstract methods of this class in the upcoming sections. - -The service must have an `identifier` static property, which is a unique identifier for the provider. You set the identifier to `shipstation`. - -A module can receive options that are set when you later add the module to Medusa's configurations. These options allow you to safely store secret values outside of your code. - -The ShipStation module requires an `api_key` option, indicating your ShipStation's API key. You receive the options as a second parameter of the service's constructor. - -### Create Client - -To send requests to ShipStation, you'll create a client class that provides the methods to send requests. You'll then use that class in your service. - -Create the file `src/modules/shipstation/client.ts` with the following content: - -![The directory structure of the Medusa application after adding the client file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339519/Medusa%20Resources/shipstation-dir-overview-3_b8im2d.jpg) - -```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights1} -import { ShipStationOptions } from "./service" -import { MedusaError } from "@medusajs/framework/utils" - -export class ShipStationClient { - options: ShipStationOptions - - constructor(options) { - this.options = options - } - - private async sendRequest(url: string, data?: RequestInit): Promise { - return fetch(`https://api.shipstation.com/v2${url}`, { - ...data, - headers: { - ...data?.headers, - "api-key": this.options.api_key, - "Content-Type": "application/json", - }, - }).then((resp) => { - const contentType = resp.headers.get("content-type") - if (!contentType?.includes("application/json")) { - return resp.text() - } - - return resp.json() - }) - .then((resp) => { - if (typeof resp !== "string" && resp.errors?.length) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - `An error occured while sending a request to ShipStation: ${ - resp.errors.map((error) => error.message) - }` - ) - } - - return resp - }) - } -} -``` - -The `ShipStationClient` class accepts the ShipStation options in its constructor and sets those options in the `options` property. - -You also add a private `sendRequest` method that accepts a path to send a request to and the request's configurations. In the method, you send a request using the Fetch API, passing the API key from the options in the request header. You also parse the response body based on its content type, and check if there are any errors to be thrown before returning the parsed response. - -You'll add more methods to send requests in the upcoming steps. - -To use the client in `ShipStationProviderService`, add it as a class property and initialize it in the constructor: - -```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights2} -// imports... -import { ShipStationClient } from "./client" - -// ... - -class ShipStationProviderService extends AbstractFulfillmentProviderService { - // properties... - protected client: ShipStationClient - - constructor({}, options: ShipStationOptions) { - // ... - this.client = new ShipStationClient(options) - } -} -``` - -You import `ShipStationClient` and add a new `client` property in `ShipStationProviderService`. In the class's constructor, you set the `client` property by initializing `ShipStationProviderService`, passing it the module's options. - -You'll use the `client` property when implementing the service's methods. - -### Implement Service Methods - -In this section, you'll go back to the `ShipStationProviderService` method to implement the abstract methods of `AbstractFulfillmentProviderService`. - -Refer to [this guide](https://docs.medusajs.com/references/fulfillment/provider/index.html.md) for a full reference of all methods, their parameters and return types. - -#### getFulfillmentOptions - -The `getFulfillmentOptions` method returns the options that this fulfillment provider supports. When admin users add shipping options later in the Medusa Admin, they'll select one of these options. - -Learn more about shipping options in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). - -ShipStation requires that a shipment must be associated with a carrier and one of its services. So, in this method, you'll retrieve the list of carriers from ShipStation and return them as fulfillment options. Shipping options created from these fulfillment options will always have access to the option's carrier and service. - -Before you start implementing methods, you'll add the expected carrier types returned by ShipStation. Create the file `src/modules/shipstation/types.ts` with the following content: - -![The directory structure of the Medusa application after adding the types file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734340402/Medusa%20Resources/shipstation-dir-overview-4_fwsle0.jpg) - -```ts title="src/modules/shipstation/types.ts" -export type Carrier = { - carrier_id: string - disabled_by_billing_plan: boolean - friendly_name: string - services: { - service_code: string - name: string - }[] - packages: { - package_code: string - }[] - [k: string]: unknown -} - -export type CarriersResponse = { - carriers: Carrier[] -} -``` - -You define a `Carrier` type that holds a carrier's details, and a `CarriersResponse` type, which is the response returned by ShipStation. - -A carrier has more fields that you can use. Refer to [ShipStation's documentation](https://docs.shipstation.com/openapi/carriers/list_carriers#carriers/list_carriers/t=response\&c=200\&path=carriers) for all carrier fields. - -Next, you'll add in `ShipStationClient` the method to retrieve the carriers from ShipStation. 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 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 - } - ] - warehouse_id?: string - shipment_status: "pending" | "processing" | "label_purchased" | "cancelled" - [k: string]: unknown -} - -``` - -You add the following types: - -- `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. - -Then, add the following methods to `ShipStationClient`: - -```ts title="src/modules/shipstation/client.ts" highlights={serviceHighlights7} -// other imports... -import { - // ... - GetShippingRatesRequest, - GetShippingRatesResponse, - RateResponse, -} from "./types" - -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: ${ - resp.rate_response.errors.map((error) => error.message) - }` - ) - } - - return resp - }) - } - - async getShipmentRates(id: string): Promise { - return await this.sendRequest(`/shipments/${id}/rates`) - } -} -``` - -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. - -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. - -Next, add to `ShipStationProviderService` a private method that'll be used to create a shipment in ShipStation and get its rates: - -```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" - -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", - } - - // TODO create shipment - } -} -``` - -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. ShipStation requires the addresses to ship the items from and to. - -To send the request, replace the `TODO` with the following: - -```ts title="src/modules/shipstation/service.ts" -// Sum the package's weight -// You can instead create different packages for each item -const packageWeight = items.reduce((sum, item) => { - // @ts-ignore - return sum + (item.variant.weight || 0) -}, 0) - -return await this.client.getShippingRates({ - shipment: { - carrier_id: carrier_id, - service_code: carrier_service_code, - ship_to, - ship_from, - validate_address: "no_validation", - items: items?.map((item) => ({ - name: item.title, - quantity: item.quantity, - sku: item.variant_sku || "", - })), - packages: [{ - weight: { - value: packageWeight, - unit: "kilogram", - }, - }], - customs: { - contents: "merchandise", - non_delivery: "return_to_sender", - }, - }, - rate_options: { - carrier_ids: [carrier_id], - service_codes: [carrier_service_code], - preferred_currency: currency_code as string, - }, -}) -``` - -You create a shipment and get its rates using the `getShippingRates` method you added to the client. You pass the method the expected request body parameters by [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates), including the carrier ID, the items to be shipped, and more. - -The above snippet assumes all items are sent in a single package. You can instead pass a package for each item, specifying its weight and optionally its height, width, and length. - -Finally, add the `calculatePrice` method to `ShipStationProviderService`: - -```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights5} -// other imports... -import { - // ... - CalculatedShippingOptionPrice, -} from "@medusajs/framework/types" - -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 - - 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. If not, you create the shipment in ShipStation using the `createShipment` method. - -Finally, you return the object to be stored in the shipping method's `data` property. 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. You can find more properties in [ShipStation's documentation](https://docs.shipstation.com/openapi/labels/create_label#labels/create_label/response\&c=200/body). - -Then, add the following methods to the `ShipStationClient`: - -```ts title="src/modules/shipstation/client.ts" -// other imports... -import { - // ... - Label, - Shipment, -} from "./types" - -export class ShipStationClient { - // ... - - async getShipment(id: string): Promise { - return await this.sendRequest(`/shipments/${id}`) - } - - async purchaseLabelForShipment(id: string): Promise
