PostgreSQL database: This is the database that will hold your Medusa application's details. -2. Redis database: This is the database that will store the Medusa server's session. -3. Medusa application in [server and worker mode](https://docs.medusajs.com/learn/production/worker-mode/index.html.md), where: - - The server mode handles incoming API requests and serving the Medusa Admin dashboard. - - The worker mode handles background tasks, such as scheduled jobs and subscribers. - -So, when choosing a hosting provider, make sure it supports deploying these resources. Also, for optimal experience, the hosting provider and plan must offer at least 2GB of RAM. - -*** - -## 1. Configure Medusa Application - -### Worker Mode - -The `workerMode` configuration determines which mode the Medusa application runs in. When you deploy the Medusa application, you deploy two instances: one in server mode, and one in worker mode. - -Learn more about worker mode in the [Worker Module chapter](https://docs.medusajs.com/learn/production/worker-mode/index.html.md). - -So, add the following configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - // ... - workerMode: process.env.MEDUSA_WORKER_MODE as "shared" | "worker" | "server", - }, -}) -``` - -Later, you’ll set different values of the `MEDUSA_WORKER_MODE` environment variable for each Medusa application deployment or instance. - -### Configure Medusa Admin - -The Medusa Admin is served by the Medusa server application. So, you need to disable it in the worker Medusa application only. - -To disable the Medusa Admin in the worker Medusa application while keeping it enabled in the server Medusa application, add the following configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - admin: { - disable: process.env.DISABLE_MEDUSA_ADMIN === "true", - }, -}) -``` - -Later, you’ll set different values of the `DISABLE_MEDUSA_ADMIN` environment variable for each Medusa application instance. - -### Configure Redis URL - -The `redisUrl` configuration specifies the connection URL to Redis to store the Medusa server's session. - -Learn more in the [Medusa Configuration documentation](https://docs.medusajs.com/learn/configurations/medusa-config#redisurl/index.html.md). - -So, add the following configuration in `medusa-config.ts` : - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - // ... - redisUrl: process.env.REDIS_URL, - }, -}) -``` - -*** - -## 2. Add predeploy Script - -Before you start the Medusa application in production, you should always run migrations and sync links. - -So, add the following script in `package.json`: - -```json -"scripts": { - // ... - "predeploy": "medusa db:migrate" -}, -``` - -*** - -## 3. Install Production Modules and Providers - -By default, your Medusa application uses modules and providers useful for development, such as the In-Memory Cache Module or the Local File Module Provider. - -It’s highly recommended to instead use modules and providers suitable for production, including: - -- [Redis Cache Module](https://docs.medusajs.com/resources/architectural-modules/cache/redis/index.html.md) -- [Redis Event Bus Module](https://docs.medusajs.com/resources/architectural-modules/event/redis/index.html.md) -- [Workflow Engine Redis Module](https://docs.medusajs.com/resources/architectural-modules/workflow-engine/redis/index.html.md) -- [S3 File Module Provider](https://docs.medusajs.com/resources/architectural-modules/file/s3/index.html.md) (or other file module providers production-ready). -- [SendGrid Notification Module Provider](https://docs.medusajs.com/resources/architectural-modules/notification/sendgrid/index.html.md) (or other notification module providers production-ready). - -Then, add these modules in `medusa-config.ts`: - -```ts title="medusa-config.ts" -import { Modules } from "@medusajs/framework/utils" - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/cache-redis", - options: { - redisUrl: process.env.REDIS_URL, - }, - }, - { - resolve: "@medusajs/medusa/event-bus-redis", - options: { - redisUrl: process.env.REDIS_URL, - }, - }, - { - resolve: "@medusajs/medusa/workflow-engine-redis", - options: { - redis: { - url: process.env.REDIS_URL, - }, - }, - }, - ], -}) -``` - -Check out the [Integrations](https://docs.medusajs.com/resources/integrations/index.html.md) and [Architectural Modules](https://docs.medusajs.com/resources/architectural-modules/index.html.md) documentation for other modules and providers to use. - -*** - -## 4. Create PostgreSQL and Redis Databases - -Your Medusa application must connect to PostgreSQL and Redis databases. So, before you deploy it, create production PostgreSQL and Redis databases. - -If your hosting provider doesn't support databases, you can use [Neon for PostgreSQL database hosting](https://neon.tech/), and [Redis Cloud for the Redis database hosting](https://redis.io/cloud/). - -After hosting both databases, keep their connection URLs for the next steps. - -*** - -## 5. Deploy Medusa Application in Server Mode - -As mentioned earlier, you'll deploy two instances or create two deployments of your Medusa application: one in server mode, and the other in worker mode. - -The deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. - -### Set Environment Variables - -When setting the environment variables of the Medusa application, set the following variables: - -```bash -COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET -JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET -STORE_CORS= # STOREFRONT URL -ADMIN_CORS= # ADMIN URL -AUTH_CORS= # STOREFRONT AND ADMIN URLS, SEPARATED BY COMMAS -DISABLE_MEDUSA_ADMIN=false -MEDUSA_WORKER_MODE=server -PORT=9000 -DATABASE_URL # POSTGRES DATABASE URL -REDIS_URL= # REDIS DATABASE URL -``` - -Where: - -- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. -- `STORE_CORS`'s value is the URL of your storefront. If you don’t have it yet, you can skip adding it for now. -- `ADMIN_CORS`'s value is the URL of the admin dashboard, which is the same as the server Medusa application. You can add it later if you don't currently have it. -- `AUTH_CORS`'s value is the URLs of any application authenticating users, customers, or other actor types, such as the storefront and admin URLs. The URLs are separated by commas. If you don’t have the URLs yet, you can set its value later. -- Set `DISABLE_MEDUSA_ADMIN`'s value to `false` so that the admin is built with the server application. -- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` -- Set the Redis database's connection URL as the value of `REDIS_URL`. - -Feel free to add any other relevant environment variables, such as for integrations and architectural modules. If you're using environment variables in your admin customizations, make sure to set them as well, as they're inlined during the build process. - -### Set Start Command - -The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`. So, you must install the dependencies in the `.medusa/server` directory, then run the `start` command in it. - -If your hosting provider doesn't support setting a current-working directory, set the start command to the following: - -```bash npm2yarn -cd .medusa/server && npm install && npm run predeploy && npm run start -``` - -Notice that you run the `predeploy` command before starting the Medusa application to run migrations and sync links whenever there's an update. - -### Set Backend URL in Admin Configuration - -The Medusa Admin is built and hosted statically. To send requests to the Medusa server application, you must set the backend URL in the Medusa Admin's configuration. - -After you’ve obtained the Medusa application’s URL, add the following configuration to `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - admin: { - // ... - backendUrl: process.env.MEDUSA_BACKEND_URL, - }, -}) -``` - -Then, push the changes to the GitHub repository or deployed application. - -In your hosting provider, add or modify the following environment variables for the Medusa application in server mode: - -```bash -ADMIN_CORS= # MEDUSA APPLICATION URL -AUTH_CORS= # ADD MEDUSA APPLICATION URL -MEDUSA_BACKEND_URL= # URL TO DEPLOYED MEDUSA APPLICATION -``` - -Where you set the value of `ADMIN_CORS` and `MEDUSA_BACKEND_URL` to the Medusa application’s URL, and you add the URL to `AUTH_CORS`. - -After setting the environment variables, make sure to restart the deployment for the changes to take effect. - -Remember to separate URLs in `AUTH_CORS` by commas. - -*** - -## 6. Deploy Medusa Application in Worker Mode - -Next, you'll deploy the Medusa application in worker mode. - -As explained in the previous section, the deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. - -### Set Environment Variables - -When setting the environment variables of the Medusa application, set the following variables: - -```bash -COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET -JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET -DISABLE_MEDUSA_ADMIN=true -MEDUSA_WORKER_MODE=worker -PORT=9000 -DATABASE_URL # POSTGRES DATABASE URL -REDIS_URL= # REDIS DATABASE URL -``` - -Where: - -- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. -- Set `DISABLE_MEDUSA_ADMIN`'s value to `true` so that the admin isn't built with the worker application. -- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` -- Set the Redis database's connection URL as the value of `REDIS_URL`. - -Feel free to add any other relevant environment variables, such as for integrations and architectural modules. - -### Set Start Command - -The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`. So, you must install the dependencies in the `.medusa/server` directory, then run the `start` command in it. - -If your hosting provider doesn't support setting a current-working directory, set the start command to the following: - -```bash npm2yarn -cd .medusa/server && npm run install && npm run start -``` - -*** - -## 7. Test Deployed Application - -Once the application is deployed and live, go to `/health`, where `` is the URL of the Medusa application in server mode. If the deployment was successful, you’ll see the `OK` response. - -The Medusa Admin is also available at `/app`. - -*** - -## Create Admin User - -If your hosting provider supports running commands in your Medusa application's directory, run the following command to create an admin user: - -```bash -npx medusa user -e admin-medusa@test.com -p supersecret -``` - -Replace the email `admin-medusa@test.com` and password `supersecret` with the credentials you want. - -You can use these credentials to log into the Medusa Admin dashboard. - - -# 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.

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) +- HTTP requests +- Workflow executions +- Query usages +- Database queries and operations *** -## Database Layer +## How to Configure Instrumentation in Medusa? -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.

So, you need to disable it in the worker Medusa application only. + +To disable the Medusa Admin in the worker Medusa application while keeping it enabled in the server Medusa application, add the following configuration in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + admin: { + disable: process.env.DISABLE_MEDUSA_ADMIN === "true", + }, +}) +``` + +Later, you’ll set different values of the `DISABLE_MEDUSA_ADMIN` environment variable for each Medusa application instance. + +### Configure Redis URL + +The `redisUrl` configuration specifies the connection URL to Redis to store the Medusa server's session. + +Learn more in the [Medusa Configuration documentation](https://docs.medusajs.com/learn/configurations/medusa-config#redisurl/index.html.md). + +So, add the following configuration in `medusa-config.ts` : + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + projectConfig: { + // ... + redisUrl: process.env.REDIS_URL, + }, +}) +``` + +*** + +## 2. Add predeploy Script + +Before you start the Medusa application in production, you should always run migrations and sync links. + +So, add the following script in `package.json`: + +```json +"scripts": { + // ... + "predeploy": "medusa db:migrate" +}, +``` + +*** + +## 3. Install Production Modules and Providers + +By default, your Medusa application uses modules and providers useful for development, such as the In-Memory Cache Module or the Local File Module Provider. + +It’s highly recommended to instead use modules and providers suitable for production, including: + +- [Redis Cache Module](https://docs.medusajs.com/resources/architectural-modules/cache/redis/index.html.md) +- [Redis Event Bus Module](https://docs.medusajs.com/resources/architectural-modules/event/redis/index.html.md) +- [Workflow Engine Redis Module](https://docs.medusajs.com/resources/architectural-modules/workflow-engine/redis/index.html.md) +- [S3 File Module Provider](https://docs.medusajs.com/resources/architectural-modules/file/s3/index.html.md) (or other file module providers production-ready). +- [SendGrid Notification Module Provider](https://docs.medusajs.com/resources/architectural-modules/notification/sendgrid/index.html.md) (or other notification module providers production-ready). + +Then, add these modules in `medusa-config.ts`: + +```ts title="medusa-config.ts" +import { Modules } from "@medusajs/framework/utils" + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/cache-redis", + options: { + redisUrl: process.env.REDIS_URL, + }, + }, + { + resolve: "@medusajs/medusa/event-bus-redis", + options: { + redisUrl: process.env.REDIS_URL, + }, + }, + { + resolve: "@medusajs/medusa/workflow-engine-redis", + options: { + redis: { + url: process.env.REDIS_URL, + }, + }, + }, + ], +}) +``` + +Check out the [Integrations](https://docs.medusajs.com/resources/integrations/index.html.md) and [Architectural Modules](https://docs.medusajs.com/resources/architectural-modules/index.html.md) documentation for other modules and providers to use. + +*** + +## 4. Create PostgreSQL and Redis Databases + +Your Medusa application must connect to PostgreSQL and Redis databases. So, before you deploy it, create production PostgreSQL and Redis databases. + +If your hosting provider doesn't support databases, you can use [Neon for PostgreSQL database hosting](https://neon.tech/), and [Redis Cloud for the Redis database hosting](https://redis.io/cloud/). + +After hosting both databases, keep their connection URLs for the next steps. + +*** + +## 5. Deploy Medusa Application in Server Mode + +As mentioned earlier, you'll deploy two instances or create two deployments of your Medusa application: one in server mode, and the other in worker mode. + +The deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. + +### Set Environment Variables + +When setting the environment variables of the Medusa application, set the following variables: + +```bash +COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET +JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET +STORE_CORS= # STOREFRONT URL +ADMIN_CORS= # ADMIN URL +AUTH_CORS= # STOREFRONT AND ADMIN URLS, SEPARATED BY COMMAS +DISABLE_MEDUSA_ADMIN=false +MEDUSA_WORKER_MODE=server +PORT=9000 +DATABASE_URL # POSTGRES DATABASE URL +REDIS_URL= # REDIS DATABASE URL +``` + +Where: + +- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. +- `STORE_CORS`'s value is the URL of your storefront. If you don’t have it yet, you can skip adding it for now. +- `ADMIN_CORS`'s value is the URL of the admin dashboard, which is the same as the server Medusa application. You can add it later if you don't currently have it. +- `AUTH_CORS`'s value is the URLs of any application authenticating users, customers, or other actor types, such as the storefront and admin URLs. The URLs are separated by commas. If you don’t have the URLs yet, you can set its value later. +- Set `DISABLE_MEDUSA_ADMIN`'s value to `false` so that the admin is built with the server application. +- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` +- Set the Redis database's connection URL as the value of `REDIS_URL`. + +Feel free to add any other relevant environment variables, such as for integrations and architectural modules. If you're using environment variables in your admin customizations, make sure to set them as well, as they're inlined during the build process. + +### Set Start Command + +The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`. So, you must install the dependencies in the `.medusa/server` directory, then run the `start` command in it. + +If your hosting provider doesn't support setting a current-working directory, set the start command to the following: + +```bash npm2yarn +cd .medusa/server && npm install && npm run predeploy && npm run start +``` + +Notice that you run the `predeploy` command before starting the Medusa application to run migrations and sync links whenever there's an update. + +### Set Backend URL in Admin Configuration + +The Medusa Admin is built and hosted statically. To send requests to the Medusa server application, you must set the backend URL in the Medusa Admin's configuration. + +After you’ve obtained the Medusa application’s URL, add the following configuration to `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + admin: { + // ... + backendUrl: process.env.MEDUSA_BACKEND_URL, + }, +}) +``` + +Then, push the changes to the GitHub repository or deployed application. + +In your hosting provider, add or modify the following environment variables for the Medusa application in server mode: + +```bash +ADMIN_CORS= # MEDUSA APPLICATION URL +AUTH_CORS= # ADD MEDUSA APPLICATION URL +MEDUSA_BACKEND_URL= # URL TO DEPLOYED MEDUSA APPLICATION +``` + +Where you set the value of `ADMIN_CORS` and `MEDUSA_BACKEND_URL` to the Medusa application’s URL, and you add the URL to `AUTH_CORS`. + +After setting the environment variables, make sure to restart the deployment for the changes to take effect. + +Remember to separate URLs in `AUTH_CORS` by commas. + +*** + +## 6. Deploy Medusa Application in Worker Mode + +Next, you'll deploy the Medusa application in worker mode. + +As explained in the previous section, the deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. + +### Set Environment Variables + +When setting the environment variables of the Medusa application, set the following variables: + +```bash +COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET +JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET +DISABLE_MEDUSA_ADMIN=true +MEDUSA_WORKER_MODE=worker +PORT=9000 +DATABASE_URL # POSTGRES DATABASE URL +REDIS_URL= # REDIS DATABASE URL +``` + +Where: + +- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. +- Set `DISABLE_MEDUSA_ADMIN`'s value to `true` so that the admin isn't built with the worker application. +- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` +- Set the Redis database's connection URL as the value of `REDIS_URL`. + +Feel free to add any other relevant environment variables, such as for integrations and architectural modules. + +### Set Start Command + +The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`.

Test Deployed Application + +Once the application is deployed and live, go to `/health`, where `` is the URL of the Medusa application in server mode. If the deployment was successful, you’ll see the `OK` response. + +The Medusa Admin is also available at `/app`. + +*** + +## Create Admin User + +If your hosting provider supports running commands in your Medusa application's directory, run the following command to create an admin user: + +```bash +npx medusa user -e admin-medusa@test.com -p supersecret +``` + +Replace the email `admin-medusa@test.com` and password `supersecret` with the credentials you want. + +You can use these credentials to log into the Medusa Admin dashboard. # Admin Development @@ -1941,6 +2214,65 @@ Refer to the [Medusa UI documentation](https://docs.medusajs.com/ui/index.html.m To build admin customizations that match the Medusa Admin's designs and layouts, refer to [this guide](https://docs.medusajs.com/resources/admin-components/index.html.md) to find common components. +# API Routes + +In this chapter, you’ll learn what API Routes are and how to create them. + +## What is an API Route? + +An API Route is an endpoint.

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). +In this chapter, you'll learn about `medusaIntegrationTestRunner` from Medusa's Testing Framework and how to use it to write integration tests. ### Prerequisites -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) +- [Testing Tools Setup](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools/index.html.md) + +## medusaIntegrationTestRunner Utility + +The `medusaIntegrationTestRunner` is from Medusa's Testing Framework and it's used to create integration tests in your Medusa project.

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) +``` *** -## 1. Create createBrandStep +### Run Tests -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 +Run the following command to run your tests: -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) - } -) +```bash npm2yarn +npm run test:integration ``` -You create a `createBrandStep` using the `createStep` function.

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. +This runs your Medusa application and runs the tests available under the `src/integrations/http` directory. *** -## 2.

Export Module Definition + +A module must export a definition that tells Medusa the name of the module and its main service.

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.

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.

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.

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

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 title="Medusa application" -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 title="Medusa application" -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 architectural module. - -For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/architectural-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. - - -# Emit Workflow and Service Events - -In this chapter, you'll learn about event types and how to emit an event in a service or workflow. - -## Event Types - -In your customization, you can emit an event, then listen to it in a subscriber and perform an asynchronus action, such as send a notification or data to a third-party system. - -There are two types of events in Medusa: - -1. Workflow event: an event that's emitted in a workflow after a commerce feature is performed. For example, Medusa emits the `order.placed` event after a cart is completed. -2. Service event: an event that's emitted to track, trace, or debug processes under the hood. For example, you can emit an event with an audit trail. - -### Which Event Type to Use? - -**Workflow events** are the most common event type in development, as most custom features and customizations are built around workflows. - -Some examples of workflow events: - -1. When a user creates a blog post and you're emitting an event to send a newsletter email. -2. When you finish syncing products to a third-party system and you want to notify the admin user of new products added. -3. When a customer purchases a digital product and you want to generate and send it to them. - -You should only go for a **service event** if you're emitting an event for processes under the hood that don't directly affect front-facing features. - -Some examples of service events: - -1. When you're tracing data manipulation and changes, and you want to track every time some custom data is changed. -2. When you're syncing data with a search engine. - -*** - -## Emit Event in a Workflow - -To emit a workflow event, use the `emitEventStep` helper step provided in the `@medusajs/medusa/core-flows` package. - -For example: - -```ts highlights={highlights} -import { - createWorkflow, -} from "@medusajs/framework/workflows-sdk" -import { - emitEventStep, -} from "@medusajs/medusa/core-flows" - -const helloWorldWorkflow = createWorkflow( - "hello-world", - () => { - // ... - - emitEventStep({ - eventName: "custom.created", - data: { - id: "123", - // other data payload - }, - }) - } -) -``` - -The `emitEventStep` accepts an object having the following properties: - -- `eventName`: The event's name. -- `data`: The data payload as an object. You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. - -In this example, you emit the event `custom.created` and pass in the data payload an ID property. - -### Test it Out - -If you execute the workflow, the event is emitted and you can see it in your application's logs. - -Any subscribers listening to the event are executed. - -*** - -## Emit Event in a Service - -To emit a service event: - -1. Resolve `event_bus` from the module's container in your service's constructor: - -### Extending Service Factory - -```ts title="src/modules/blog/service.ts" highlights={["9"]} -import { IEventBusService } from "@medusajs/framework/types" -import { MedusaService } from "@medusajs/framework/utils" - -class BlogModuleService extends MedusaService({ - Post, -}){ - protected eventBusService_: AbstractEventBusModuleService - - constructor({ event_bus }) { - super(...arguments) - this.eventBusService_ = event_bus - } -} -``` - -### Without Service Factory - -```ts title="src/modules/blog/service.ts" highlights={["6"]} -import { IEventBusService } from "@medusajs/framework/types" - -class BlogModuleService { - protected eventBusService_: AbstractEventBusModuleService - - constructor({ event_bus }) { - this.eventBusService_ = event_bus - } -} -``` - -2. Use the event bus service's `emit` method in the service's methods to emit an event: - -```ts title="src/modules/blog/service.ts" highlights={serviceHighlights} -class BlogModuleService { - // ... - performAction() { - // TODO perform action - - this.eventBusService_.emit({ - name: "custom.event", - data: { - id: "123", - // other data payload - }, - }) - } -} -``` - -The method accepts an object having the following properties: - -- `name`: The event's name. -- `data`: The data payload as an object. You can pass any properties in the object, and subscribers listening to the event will receive this data in the event's payload. - -3. By default, the Event Module's service isn't injected into your module's container. To add it to the container, pass it in the module's registration object in `medusa-config.ts` in the `dependencies` property: - -```ts title="medusa-config.ts" highlights={depsHighlight} -import { Modules } from "@medusajs/framework/utils" - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/blog", - dependencies: [ - Modules.EVENT_BUS, - ], - }, - ], -}) -``` - -The `dependencies` property accepts an array of module registration keys. The specified modules' main services are injected into the module's container. - -That's how you can resolve it in your module's main service's constructor. - -### Test it Out - -If you execute the `performAction` method of your service, the event is emitted and you can see it in your application's logs. - -Any subscribers listening to the event are also executed. - - # Add Columns to a Link Table In this chapter, you'll learn how to add custom columns to a link definition's table and manage them. @@ -11576,497 +11354,6 @@ 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). Refer to the [Read-Only Module Links chapter](https://docs.medusajs.com/learn/fundamentals/module-links/read-only/index.html.md) for more information on read-only links and their direction. - -## Link Direction - -The module link's direction depends on the order you pass the data model configuration parameters to `defineLink`. - -For example, the following defines a link from the Blog Module's `post` data model to the Product Module's `product` data model: - -```ts -export default defineLink( - BlogModule.linkable.post, - ProductModule.linkable.product -) -``` - -Whereas the following defines a link from the Product Module's `product` data model to the Blog Module's `post` data model: - -```ts -export default defineLink( - ProductModule.linkable.product, - BlogModule.linkable.post -) -``` - -The above links are two different links that serve different purposes. - -*** - -## Which Link Direction to Use? - -### Extend Data Models - -If you're adding a link to a data model to extend it and add new fields, define the link from the main data model to the custom data model. - -For example, consider you want to add a `subtitle` custom field to the `product` data model. To do that, you define a `Subtitle` data model in your module, then define a link from the `Product` data model to it: - -```ts -export default defineLink( - ProductModule.linkable.product, - BlogModule.linkable.subtitle -) -``` - -### Associate Data Models - -If you're linking data models to indicate an association between them, define the link from the custom data model to the main data model. - -For example, consider you have `Post` data model representing a blog post, and you want to associate a blog post with a product. To do that, define a link from the `Post` data model to `Product`: - -```ts -export default defineLink( - BlogModule.linkable.post, - ProductModule.linkable.product -) -``` - - -# Query Context - -In this chapter, you'll learn how to pass contexts when retrieving data with [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). - -## What is Query Context? - -Query context is a way to pass additional information when retrieving data with Query. This data can be useful when applying custom transformations to the retrieved data based on the current context. - -For example, consider you have a Blog Module with posts and authors. You can accept the user's language as a context and return the posts in the user's language. Another example is how Medusa uses Query Context to [retrieve product variants' prices based on the customer's currency](https://docs.medusajs.com/resources/commerce-modules/product/guides/price/index.html.md). - -*** - -## How to Use Query Context - -The `query.graph` method accepts an optional `context` parameter that can be used to pass additional context either to the data model you're retrieving (for example, `post`), or its related and linked models (for example, `author`). - -You initialize a context using `QueryContext` from the Modules SDK. It accepts an object of contexts as an argument. - -For example, to retrieve posts using Query while passing the user's language as a context: - -```ts -const { data } = await query.graph({ - entity: "post", - fields: ["*"], - context: QueryContext({ - lang: "es", - }), -}) -``` - -In this example, you pass in the context a `lang` property whose value is `es`. - -Then, to handle the context while retrieving records of the data model, in the associated module's service you override the generated `list` method of the data model. - -For example, continuing the example above, you can override the `listPosts` method of the Blog Module's service to handle the context: - -```ts highlights={highlights2} -import { MedusaContext, MedusaService } from "@medusajs/framework/utils" -import { Context, FindConfig } from "@medusajs/framework/types" -import Post from "./models/post" -import Author from "./models/author" - -class BlogModuleService extends MedusaService({ - Post, - Author, -}){ - // @ts-ignore - async listPosts( - filters?: any, - config?: FindConfig | undefined, - @MedusaContext() sharedContext?: Context | undefined - ) { - const context = filters.context ?? {} - delete filters.context - - let posts = await super.listPosts(filters, config, sharedContext) - - if (context.lang === "es") { - posts = posts.map((post) => { - return { - ...post, - title: post.title + " en español", - } - }) - } - - return posts - } -} - -export default BlogModuleService -``` - -In the above example, you override the generated `listPosts` method. This method receives as a first parameter the filters passed to the query, but it also includes a `context` property that holds the context passed to the query. - -You extract the context from `filters`, then retrieve the posts using the parent's `listPosts` method. After that, if the language is set in the context, you transform the titles of the posts. - -All posts returned will now have their titles appended with "en español". - -Learn more about the generated `list` method in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/list/index.html.md). - -### Using Pagination with Query - -If you pass pagination fields to `query.graph`, you must also override the `listAndCount` method in the service. - -For example, following along with the previous example, you must override the `listAndCountPosts` method of the Blog Module's service: - -```ts -import { MedusaContext, MedusaService } from "@medusajs/framework/utils" -import { Context, FindConfig } from "@medusajs/framework/types" -import Post from "./models/post" -import Author from "./models/author" - -class BlogModuleService extends MedusaService({ - Post, - Author, -}){ - // @ts-ignore - async listAndCountPosts( - filters?: any, - config?: FindConfig | undefined, - @MedusaContext() sharedContext?: Context | undefined - ) { - const context = filters.context ?? {} - delete filters.context - - const result = await super.listAndCountPosts( - filters, - config, - sharedContext - ) - - if (context.lang === "es") { - result.posts = posts.map((post) => { - return { - ...post, - title: post.title + " en español", - } - }) - } - - return result - } -} - -export default BlogModuleService -``` - -Now, the `listAndCountPosts` method will handle the context passed to `query.graph` when you pass pagination fields. You can also move the logic to transform the posts' titles to a separate method and call it from both `listPosts` and `listAndCountPosts`. - -*** - -## Passing Query Context to Related Data Models - -If you're retrieving a data model and you want to pass context to its associated model in the same module, you can pass them as part of `QueryContext`'s parameter, then handle them in the same `list` method. - -For linked data models, check out the [next section](#passing-query-context-to-linked-data-models). - -For example, to pass a context for the post's authors: - -```ts highlights={highlights3} -const { data } = await query.graph({ - entity: "post", - fields: ["*"], - context: QueryContext({ - lang: "es", - author: QueryContext({ - lang: "es", - }), - }), -}) -``` - -Then, in the `listPosts` method, you can handle the context for the post's authors: - -```ts highlights={highlights4} -import { MedusaContext, MedusaService } from "@medusajs/framework/utils" -import { Context, FindConfig } from "@medusajs/framework/types" -import Post from "./models/post" -import Author from "./models/author" - -class BlogModuleService extends MedusaService({ - Post, - Author, -}){ - // @ts-ignore - async listPosts( - filters?: any, - config?: FindConfig | undefined, - @MedusaContext() sharedContext?: Context | undefined - ) { - const context = filters.context ?? {} - delete filters.context - - let posts = await super.listPosts(filters, config, sharedContext) - - const isPostLangEs = context.lang === "es" - const isAuthorLangEs = context.author?.lang === "es" - - if (isPostLangEs || isAuthorLangEs) { - posts = posts.map((post) => { - return { - ...post, - title: isPostLangEs ? post.title + " en español" : post.title, - author: { - ...post.author, - name: isAuthorLangEs ? post.author.name + " en español" : post.author.name, - }, - } - }) - } - - return posts - } -} - -export default BlogModuleService -``` - -The context in `filters` will also have the context for `author`, which you can use to make transformations to the post's authors. - -*** - -## Passing Query Context to Linked Data Models - -If you're retrieving a data model and you want to pass context to a linked model in a different module, pass to the `context` property an object instead, where its keys are the linked model's name and the values are the context for that linked model. - -For example, consider the Product Module's `Product` data model is linked to the Blog Module's `Post` data model. You can pass context to the `Post` data model while retrieving products like so: - -```ts highlights={highlights5} -const { data } = await query.graph({ - entity: "product", - fields: ["*", "post.*"], - context: { - post: QueryContext({ - lang: "es", - }), - }, -}) -``` - -In this example, you retrieve products and their associated posts.

This data can be useful when applying custom transformations to the retrieved data based on the current context. + +For example, consider you have a Blog Module with posts and authors. You can accept the user's language as a context and return the posts in the user's language. Another example is how Medusa uses Query Context to [retrieve product variants' prices based on the customer's currency](https://docs.medusajs.com/resources/commerce-modules/product/guides/price/index.html.md). + +*** + +## How to Use Query Context + +The `query.graph` method accepts an optional `context` parameter that can be used to pass additional context either to the data model you're retrieving (for example, `post`), or its related and linked models (for example, `author`). + +You initialize a context using `QueryContext` from the Modules SDK. It accepts an object of contexts as an argument. + +For example, to retrieve posts using Query while passing the user's language as a context: + +```ts +const { data } = await query.graph({ + entity: "post", + fields: ["*"], + context: QueryContext({ + lang: "es", + }), +}) +``` + +In this example, you pass in the context a `lang` property whose value is `es`. + +Then, to handle the context while retrieving records of the data model, in the associated module's service you override the generated `list` method of the data model. + +For example, continuing the example above, you can override the `listPosts` method of the Blog Module's service to handle the context: + +```ts highlights={highlights2} +import { MedusaContext, MedusaService } from "@medusajs/framework/utils" +import { Context, FindConfig } from "@medusajs/framework/types" +import Post from "./models/post" +import Author from "./models/author" + +class BlogModuleService extends MedusaService({ + Post, + Author, +}){ + // @ts-ignore + async listPosts( + filters?: any, + config?: FindConfig | undefined, + @MedusaContext() sharedContext?: Context | undefined + ) { + const context = filters.context ?? {} + delete filters.context + + let posts = await super.listPosts(filters, config, sharedContext) + + if (context.lang === "es") { + posts = posts.map((post) => { + return { + ...post, + title: post.title + " en español", + } + }) + } + + return posts + } +} + +export default BlogModuleService +``` + +In the above example, you override the generated `listPosts` method. This method receives as a first parameter the filters passed to the query, but it also includes a `context` property that holds the context passed to the query. + +You extract the context from `filters`, then retrieve the posts using the parent's `listPosts` method. After that, if the language is set in the context, you transform the titles of the posts. + +All posts returned will now have their titles appended with "en español". + +Learn more about the generated `list` method in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/list/index.html.md). + +### Using Pagination with Query + +If you pass pagination fields to `query.graph`, you must also override the `listAndCount` method in the service. + +For example, following along with the previous example, you must override the `listAndCountPosts` method of the Blog Module's service: + +```ts +import { MedusaContext, MedusaService } from "@medusajs/framework/utils" +import { Context, FindConfig } from "@medusajs/framework/types" +import Post from "./models/post" +import Author from "./models/author" + +class BlogModuleService extends MedusaService({ + Post, + Author, +}){ + // @ts-ignore + async listAndCountPosts( + filters?: any, + config?: FindConfig | undefined, + @MedusaContext() sharedContext?: Context | undefined + ) { + const context = filters.context ?? {} + delete filters.context + + const result = await super.listAndCountPosts( + filters, + config, + sharedContext + ) + + if (context.lang === "es") { + result.posts = posts.map((post) => { + return { + ...post, + title: post.title + " en español", + } + }) + } + + return result + } +} + +export default BlogModuleService +``` + +Now, the `listAndCountPosts` method will handle the context passed to `query.graph` when you pass pagination fields. You can also move the logic to transform the posts' titles to a separate method and call it from both `listPosts` and `listAndCountPosts`. + +*** + +## Passing Query Context to Related Data Models + +If you're retrieving a data model and you want to pass context to its associated model in the same module, you can pass them as part of `QueryContext`'s parameter, then handle them in the same `list` method. + +For linked data models, check out the [next section](#passing-query-context-to-linked-data-models). + +For example, to pass a context for the post's authors: + +```ts highlights={highlights3} +const { data } = await query.graph({ + entity: "post", + fields: ["*"], + context: QueryContext({ + lang: "es", + author: QueryContext({ + lang: "es", + }), + }), +}) +``` + +Then, in the `listPosts` method, you can handle the context for the post's authors: + +```ts highlights={highlights4} +import { MedusaContext, MedusaService } from "@medusajs/framework/utils" +import { Context, FindConfig } from "@medusajs/framework/types" +import Post from "./models/post" +import Author from "./models/author" + +class BlogModuleService extends MedusaService({ + Post, + Author, +}){ + // @ts-ignore + async listPosts( + filters?: any, + config?: FindConfig | undefined, + @MedusaContext() sharedContext?: Context | undefined + ) { + const context = filters.context ?? {} + delete filters.context + + let posts = await super.listPosts(filters, config, sharedContext) + + const isPostLangEs = context.lang === "es" + const isAuthorLangEs = context.author?.lang === "es" + + if (isPostLangEs || isAuthorLangEs) { + posts = posts.map((post) => { + return { + ...post, + title: isPostLangEs ? post.title + " en español" : post.title, + author: { + ...post.author, + name: isAuthorLangEs ? post.author.name + " en español" : post.author.name, + }, + } + }) + } + + return posts + } +} + +export default BlogModuleService +``` + +The context in `filters` will also have the context for `author`, which you can use to make transformations to the post's authors. + +*** + +## Passing Query Context to Linked Data Models + +If you're retrieving a data model and you want to pass context to a linked model in a different module, pass to the `context` property an object instead, where its keys are the linked model's name and the values are the context for that linked model. + +For example, consider the Product Module's `Product` data model is linked to the Blog Module's `Post` data model. You can pass context to the `Post` data model while retrieving products like so: + +```ts highlights={highlights5} +const { data } = await query.graph({ + entity: "product", + fields: ["*", "post.*"], + context: { + post: QueryContext({ + lang: "es", + }), + }, +}) +``` + +In this example, you retrieve products and their associated posts.

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 title="Medusa application" +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 title="Medusa application" +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 architectural module. + +For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/architectural-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. + + # Scheduled Jobs Number of Executions In this chapter, you'll learn how to set a limit on the number of times a scheduled job is executed. @@ -13229,37 +13472,6 @@ export const countProductsStep = createStep( Your workflow can use services of both custom and commerce modules, supporting you in building custom flows without having to re-build core commerce features. -# Architectural Modules - -In this chapter, you’ll learn about architectural modules. - -## What is an Architectural Module? - -An architectural 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 object has a `container` property that you use to resolve resources from the Medusa container. + +For example: + +```ts +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { ContainerRegistrationKeys } from "@medusajs/framework/utils" + +const step1 = createStep( + "step-1", + async () => { + return new StepResponse( + `Hello from step one!`, + { message: "Oops!

You may have the following step: + +```ts +// other imports... +import { promiseAll } from "@medusajs/framework/utils" + +type StepInput = { + ids: string[] +} + +const step1 = createStep( + "step-1", + async ({ ids }: StepInput, { container }) => { + const erpModuleService = container.resolve( + ERP_MODULE + ) + const prevData: unknown[] = [] + + await promiseAll( + ids.map(async (id) => { + const data = await erpModuleService.retrieve(id) + + await erpModuleService.delete(id) + + prevData.push(id) + }) + ) + + return new StepResponse(ids, prevData) + } +) +``` + +In the step, you loop over the IDs to retrieve the item's data, store them in a `prevData` variable, then delete them using the ERP Module's service. You then pass the `prevData` variable to the compensation function. + +However, if an error occurs in the loop, the `prevData` variable won't be passed to the compensation function as the execution never reached the return statement. + +To handle errors in the loop so that the compensation function receives the last version of `prevData` before the error occurred, you wrap the loop in a try-catch block. Then, in the catch block, you invoke and return the `StepResponse.permanentFailure` function: + +```ts highlights={highlights} +try { + await promiseAll( + ids.map(async (id) => { + const data = await erpModuleService.retrieve(id) + + await erpModuleService.delete(id) + + prevData.push(id) + }) + ) +} catch (e) { + return StepResponse.permanentFailure( + `An error occurred: ${e}`, + prevData + ) +} +``` + +The `StepResponse.permanentFailure` fails the step and its workflow, triggering current and previous steps' compensation functions. The `permanentFailure` function accepts as a first parameter the error message, which is saved in the workflow's error details, and as a second parameter the data to pass to the compensation function. + +So, if an error occurs during the loop, the compensation function will still receive the `prevData` variable to undo the changes made before the step failed. + + +# Execute Another Workflow + +In this chapter, you'll learn how to execute a workflow in another. + +## Execute in a Workflow + +To execute a workflow in another, use the `runAsStep` method that every workflow has. + +For example: + +```ts highlights={workflowsHighlights} collapsibleLines="1-7" expandMoreButton="Show Imports" +import { + createWorkflow, +} from "@medusajs/framework/workflows-sdk" +import { + createProductsWorkflow, +} from "@medusajs/medusa/core-flows" + +const workflow = createWorkflow( + "hello-world", + async (input) => { + const products = createProductsWorkflow.runAsStep({ + input: { + products: [ + // ... + ], + }, + }) + + // ... + } +) +``` + +Instead of invoking the workflow and passing it the container, you use its `runAsStep` method and pass it an object as a parameter. + +The object has an `input` property to pass input to the workflow. + +*** + +## Preparing Input Data + +If you need to perform some data manipulation to prepare the other workflow's input data, use `transform` from the Workflows SDK. + +Learn about transform in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation/index.html.md). + +For example: + +```ts highlights={transformHighlights} collapsibleLines="1-12" +import { + createWorkflow, + transform, +} from "@medusajs/framework/workflows-sdk" +import { + createProductsWorkflow, +} from "@medusajs/medusa/core-flows" + +type WorkflowInput = { + title: string +} + +const workflow = createWorkflow( + "hello-product", + async (input: WorkflowInput) => { + const createProductsData = transform({ + input, + }, (data) => [ + { + title: `Hello ${data.input.title}`, + }, + ]) + + const products = createProductsWorkflow.runAsStep({ + input: { + products: createProductsData, + }, + }) + + // ... + } +) +``` + +In this example, you use the `transform` function to prepend `Hello` to the title of the product.

The Medusa application's commerce features are built around [commerce modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md), which are available out-of-the-box. These features include management capabilities related to carts, orders, promotions, and more. + +A loyalty point system allows customers to earn points for purchases, which can be redeemed for discounts or rewards.

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

It accepts two parameters: + +- The data to perform manipulation on. In this case, you pass the cart's details and the amount to be discounted. +- A function that receives the data from the first parameter, and returns the transformed data. + +In the transformation function, you prepare th data of the loyalty promotion to be created. Some key details include: + +- You set the discount amount in the application method of the promotion. +- You add a rule to the promotion that ensures it can be used only in carts having their `customer_id` equal to this customer's ID. This prevents other customers from using this promotion. +- You create a campaign for the promotion, and you set the campaign budget to a single usage. This prevents the customer from using the promotion again. + +Learn more about promotion concepts in the [Promotion Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/index.html.md)'s documentation. + +You can now use the returned data to create a promotion and apply it to the cart. Replace the new `TODO` with the following: + +```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={createLoyaltyPromoStepHighlights} +const loyaltyPromo = createPromotionsStep([ + promoToCreate +] as CreatePromotionDTO[]) + +const { metadata, ...updatePromoData } = transform({ + carts, + promoToCreate, + loyaltyPromo +}, (data) => { + const promos = [ + ...(data.carts[0].promotions?.map((promo) => promo?.code).filter(Boolean) || []) as string[], + data.promoToCreate.code + ] + + return { + cart_id: data.carts[0].id, + promo_codes: promos, + action: PromotionActions.ADD, + metadata: { + loyalty_promo_id: data.loyaltyPromo[0].id + } + } +}) + +updateCartPromotionsWorkflow.runAsStep({ + input: updatePromoData +}) + +updateCartsStep([ + { + id: input.cart_id, + metadata + } +]) + +// retrieve cart with updated promotions +// @ts-ignore +const { data: updatedCarts } = useQueryGraphStep({ + entity: "cart", + fields, + filters: { id: input.cart_id }, +}).config({ name: "retrieve-cart" }) + +return new WorkflowResponse(updatedCarts[0]) +``` + +In the rest of the workflow, you: + +- Create the loyalty promotion using the data you prepared earlier using the `createPromotionsStep`. +- Use the `transform` function to prepare the data to update the cart's promotions.

You remove the `loyalty_promo_id` from the metadata. +- Update the cart's metadata with the new metadata using the `updateCartsStep`. +- Deactivate the loyalty promotion using the `updatePromotionsStep`. +- Retrieve the cart's details again using `useQueryGraphStep` to get the updated cart with the new loyalty promotion. +- Return the cart's details in a `WorkflowResponse` instance. + +### Create the API Route + +Next, you'll create the API route that executes this workflow. + +To create the API route, add the following in `src/api/store/carts/[id]/loyalty-points/route.ts`: + +```ts title="src/api/store/carts/[id]/loyalty-points/route.ts" +// other imports... +import { removeLoyaltyFromCartWorkflow } from "../../../../../workflows/remove-loyalty-from-cart"; + +// ... +export async function DELETE( + req: MedusaRequest, + res: MedusaResponse +) { + const { id: cart_id } = req.params + + const { result: cart } = await removeLoyaltyFromCartWorkflow(req.scope) + .run({ + input: { + cart_id + } + }) + + res.json({ cart }) +} +``` + +You export a `DELETE` route handler, which exposes a `DELETE` API route at `/store/carts/[id]/loyalty-points`. + +In the route handler, you execute the `removeLoyaltyFromCartWorkflow` workflow, passing it the cart ID as an input. You return the cart's details in the response. + +You can now use this API route in the Next.js Starter Storefront. + +### Remove Loyalty Points in the Storefront + +In the Next.js Starter Storefront, you need to add a server action function that sends a request to the API route you created earlier. Then, you'll use that function when the customer clicks the "Remove Loyalty Points" button, which shows when the cart has a loyalty promotion applied. + +To add the function, add the following to `src/lib/data/cart.ts`: + +```ts title="src/lib/data/cart.ts" badgeLabel="Storefront" badgeColor="blue" +export async function removeLoyaltyPointsOnCart() { + const cartId = await getCartId() + const headers = { + ...(await getAuthHeaders()), + } + const next = { + ...(await getCacheOptions("carts")), + } + + return await sdk.client.fetch<{ + cart: HttpTypes.StoreCart & { + promotions: HttpTypes.StorePromotion[] + } + }>(`/store/carts/${cartId}/loyalty-points`, { + method: "DELETE", + headers, + }) + .then(async (result) => { + const cartCacheTag = await getCacheTag("carts") + revalidateTag(cartCacheTag) + + return result + }) +} +``` + +You create a `removeLoyaltyPointsOnCart` function that sends a request to the API route you created earlier. + +In the function, you retrieve the cart ID stored in the cookie using the `getCartId` function, which is available in the Next.js Starter Storefront. + +Then, you send the request to the API route. Once the request is resolved successfully, you revalidate the cart cache tag to ensure that the cart's details are updated and refetched by other components. This ensures that the promotion is removed from the checkout summary without needing to refresh the page. + +Finally, you'll use this function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. + +At the top of `src/modules/checkout/components/loyalty-points/index.tsx`, add the following import: + +```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" +import { removeLoyaltyPointsOnCart } from "../../../../lib/data/cart" +``` + +Then, replace the `TODO` in `handleTogglePromotion` with the following: + +```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" +await removeLoyaltyPointsOnCart() +``` + +In the `handleTogglePromotion` function, you call the `removeLoyaltyPointsOnCart` function if the cart has a loyalty promotion. This will send a request to the API route you created earlier, which will execute the workflow that removes the loyalty promotion from the cart. + +### Test it Out + +To test out removing the loyalty points from the cart, start the Medusa application and Next.js Starter Storefront. + +Then, in the checkout flow as an authenticated customer, after applying the loyalty points, click on the "Remove Loyalty Points" button. The checkout summary will be updated with the removed promotion and the discount amount. + +![The "Remove Loyalty Points" button is shown in the "Loyalty Points" section](https://res.cloudinary.com/dza7lstvk/image/upload/v1744204436/Medusa%20Resources/Screenshot_2025-04-09_at_4.13.24_PM_xt5trh.png) + +*** + +## Step 9: Validate Loyalty Points on Cart Completion + +After the customer applies the loyalty points to the cart and places the order, you need to validate that the customer actually has the loyalty points. This prevents edge cases where the customer may have applied the loyalty points previously but they don't have them anymore. + +So, in this step, you'll hook into Medusa's cart completion flow to perform the validation. + +Since Medusa uses workflows in its API routes, it allows you to hook into them and perform custom functionalities using [Workflow Hooks](https://docs.medusajs.com/docs/learn/fundamentals/workflows/workflow-hooks/index.html.md). A workflow hook is a point in a workflow where you can inject custom functionality as a step function, called a hook handler. + +Medusa uses the [completeCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/completeCartWorkflow/index.html.md) hook to complete the cart and place an order. This workflow has a `validate` hook that allows you to perform custom validation before the cart is completed. + +To consume the `validate` hook, create the file `src/workflows/hooks/complete-cart.ts` with the following content: + +```ts title="src/workflows/hooks/complete-cart.ts" highlights={completeCartWorkflowHookHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" +import { completeCartWorkflow } from "@medusajs/medusa/core-flows"; +import LoyaltyModuleService from "../../modules/loyalty/service"; +import { LOYALTY_MODULE } from "../../modules/loyalty"; +import { CartData, getCartLoyaltyPromotion } from "../../utils/promo"; +import { MedusaError } from "@medusajs/framework/utils"; + +completeCartWorkflow.hooks.validate( + async ({ cart }, { container }) => { + const query = container.resolve("query") + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + const { data: carts } = await query.graph({ + entity: "cart", + fields: [ + "id", + "promotions.*", + "customer.*", + "promotions.rules.*", + "promotions.rules.values.*", + "promotions.application_method.*", + "metadata" + ], + filters: { + id: cart.id + } + }, { + throwIfKeyNotFound: true + }) + + const loyaltyPromo = getCartLoyaltyPromotion( + carts[0] as unknown as CartData + ) + + if (!loyaltyPromo) { + return + } + + const customerLoyaltyPoints = await loyaltyModuleService.getPoints( + carts[0].customer!.id + ) + const requiredPoints = await loyaltyModuleService.calculatePointsFromAmount( + loyaltyPromo.application_method!.value as number + ) + + if (customerLoyaltyPoints < requiredPoints) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `Customer does not have enough loyalty points. Required: ${ + requiredPoints + }, Available: ${customerLoyaltyPoints}` + ) + } + } +) +``` + +Workflows have a special `hooks` property that includes all the hooks tht you can consume in that workflow. You consume the hook by invoking it from the workflow's `hooks` property. + +Since the hook is essentially a step function, it accepts the following parameters: + +- The hook's input passed from the workflow, which differs for each hook. The `validate` hook receives an object having the cart's details. +- The step context object, which contains the Medusa container. You can use it to resolve services and perform actions. + +In the hook, you resolve Query and the Loyalty Module's service. Then, you use Query to retrieve the cart's necessary details, including its promotions, customer, and metadata. + +After that, you retrieve the customer's loyalty points and calculate the required points to apply the loyalty promotion. + +If the customer doesn't have enough loyalty points, you throw an error. This will prevent the cart from being completed if the customer doesn't have enough loyalty points. + +*** + +## Test Out Cart Completion with Loyalty Points + +Since you now have the entire loyalty points flow implemented, you can test it out by going through the checkout flow, applying the loyalty points to the cart. + +When you place the order, if the customer has sufficient loyalty points, the validation hook will pass. + +Then, the `order.placed` event will be emitted, which will execute the subscriber that calls the `handleOrderPointsWorkflow`. + +In the workflow, since the order's cart has a loyalty promotion, the points equivalent to the promotion will be deducted, and the promotion becomes inactive. + +You can confirm that the loyalty points were deducted either by sending a request to the [retrieve loyalty points API route](#step-5-retrieve-loyalty-points-api-route), or by going through the checkout process again in the storefront. + +*** + +## Next Steps + +You've now implement a loyalty points system in Medusa. There's still more that you can implement based on your use case: + +- Add loyalty points on registration or other events.

[Get in touch](https://medusajs.com/contact) for early access. - -When you install a Medusa application, you get a fully-fledged commerce platform with a Framework for customization. The Medusa application's commerce features are built around [commerce modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md), which are available out-of-the-box. These features include management capabilities related to carts, orders, promotions, and more. - -A loyalty point system allows customers to earn points for purchases, which can be redeemed for discounts or rewards. In this tutorial, you'll learn how to customize the Medusa application to implement a loyalty points system. - -You can follow this tutorial whether you're new to Medusa or an advanced Medusa developer. - -## Summary - -By following this tutorial, you will learn how to: - -- Install and set up Medusa. -- Define models to store loyalty points and the logic to manage them. -- Build flows that allow customers to earn and redeem points during checkout. - - Points are redeemed through dynamic promotions specific to the customer. -- Customize the cart completion flow to validate applied loyalty points. - -![Diagram illustrating redeem loyalty points flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1744126213/Medusa%20Resources/redeem-points-flow_kzgkux.jpg) - -- [Loyalty Points Repository](https://github.com/medusajs/examples/tree/main/loyalty-points): Find the full code for this guide in this repository. -- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1744212595/OpenApi/Loyalty-Points_jwi5e9.yaml): Import this OpenApi Specs file into tools like Postman. - -*** - -## Step 1: Install a Medusa Application - -### Prerequisites - -- [Node.js v20+](https://nodejs.org/en/download) -- [Git CLI tool](https://git-scm.com/downloads) -- [PostgreSQL](https://www.postgresql.org/download/) - -Start by installing the Medusa application on your machine with the following command: - -```bash -npx create-medusa-app@latest -``` - -You'll first be asked for the project's name. Then, when asked whether you want to install the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md), choose Yes. - -Afterward, the installation process will start, which will install the Medusa application in a directory with your project's name, and the Next.js Starter Storefront in a separate directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more in [Medusa's Architecture documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user.

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

In this case, you pass the cart's details and the amount to be discounted. -- A function that receives the data from the first parameter, and returns the transformed data. - -In the transformation function, you prepare th data of the loyalty promotion to be created.

You can add in the plugin [API Routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md), [Workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md), and other customizations, as you'll see in this guide. Afterward, you can test it out locally in a Medusa application, then publish it to npm to install and use it in any Medusa application. + +Refer to the [Plugins](https://docs.medusajs.com/docs/learn/fundamentals/plugins/index.html.md) documentation to learn more about plugins. + +A Medusa plugin is set up in a different project, giving you the flexibility in building and publishing it, while providing you with the tools to test it out locally in a Medusa application. + +To create a new Medusa plugin project, run the following command in a directory different than that of the Medusa application: + +```bash npm2yarn +npx create-medusa-app@latest medusa-plugin-magento --plugin +``` + +Where `medusa-plugin-magento` is the name of the plugin's directory and the name set in the plugin's `package.json`. So, if you wish to publish it to NPM later under a different name, you can change it here in the command or later in `package.json`. + +Once the installation process is done, a new directory named `medusa-plugin-magento` will be created with the plugin project files. + +![Directory structure of a plugin project](https://res.cloudinary.com/dza7lstvk/image/upload/v1737019441/Medusa%20Book/project-dir_q4xtri.jpg) + +*** + +## Step 3: Set up Plugin in Medusa Application + +Before you start your development, you'll set up the plugin in the Medusa application you installed in the first step. This will allow you to test the plugin during your development process. + +In the plugin's directory, run the following command to publish the plugin to the local package registry: + +```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, you'll install the plugin in the Medusa application from the local registry. + +If you've installed your Medusa project before v2.3.1, you must install [yalc](https://github.com/wclr/yalc) as a development dependency first. + +Run the following command in the Medusa application's directory to install the plugin: + +```bash title="Medusa application" +npx medusa plugin:add medusa-plugin-magento +``` + +This command installs the plugin in the Medusa application from the local package registry. + +Next, register the plugin in the `medusa-config.ts` file of the Medusa application: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "medusa-plugin-magento", + options: { + // TODO add options + }, + }, + ], +}) +``` + +You add the plugin to the array of plugins. Later, you'll pass options useful to retrieve data from Magento. + +Finally, to ensure your plugin's changes are constantly published to the local registry, simplifying your testing process, keep the following command running in the plugin project during development: + +```bash title="Plugin project" +npx medusa plugin:develop +``` + +*** + +## Step 4: Implement Magento Module + +To connect to external applications in Medusa, you create a custom module. 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 Magento Module in the Magento plugin that connects to a Magento server's REST APIs and retrieves data, such as products. + +Refer to the [Modules](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) documentation to learn more about modules. + +### Create Module Directory + +A module is created under the `src/modules` directory of your plugin. So, create the directory `src/modules/magento`. + +![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739272368/magento-1_ikev4x.jpg) + +### Create Module's 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 external systems or the database, which is useful if your module defines tables in the database. + +In this section, you'll create the Magento Module's service that connects to Magento's REST APIs and retrieves data. + +Start by creating the file `src/modules/magento/service.ts` in the plugin with the following content: + +![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739272483/magento-2_ajetpr.jpg) + +```ts title="src/modules/magento/service.ts" +type Options = { + baseUrl: string + storeCode?: string + username: string + password: string + migrationOptions?: { + imageBaseUrl?: string + } +} + +export default class MagentoModuleService { + private options: Options + + constructor({}, options: Options) { + this.options = { + ...options, + storeCode: options.storeCode || "default", + } + } +} +``` + +You create a `MagentoModuleService` that has an `options` property to store the module's options. These options include: + +- `baseUrl`: The base URL of the Magento server. +- `storeCode`: The store code of the Magento store, which is `default` by default. +- `username`: The username of a Magento admin user to authenticate with the Magento server. +- `password`: The password of the Magento admin user. +- `migrationOptions`: Additional options useful for migrating data, such as the base URL to use for product images. + +The service's constructor accepts as a first parameter the [Module Container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md), which allows you to access resources available for the module. 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 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. + +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. + +Lastly, add an `isAccessTokenExpired` method that checks if the access token has expired: + +```ts title="src/modules/magento/service.ts" +export default class MagentoModuleService { + // ... + async isAccessTokenExpired(): Promise { + return !this.accessToken || this.accessToken.expiresAt < new Date() + } +} +``` + +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. + +### Retrieve Products from Magento + +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. + +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: + +![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/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() + } + + // 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 `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/magento/index.ts` with the following content: + +![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 MagentoModuleService from "./service" + +export const MAGENTO_MODULE = "magento" + +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 `magento`. +2. An object with a required property `service` indicating the module's service. + +You'll later use the module's service to retrieve products from Magento. + +### Pass Options to Plugin + +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. + +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({ + // ... + plugins: [ + { + resolve: "medusa-plugin-magento", + options: { + baseUrl: process.env.MAGENTO_BASE_URL, + username: process.env.MAGENTO_USERNAME, + password: process.env.MAGENTO_PASSWORD, + migrationOptions: { + imageBaseUrl: process.env.MAGENTO_IMAGE_BASE_URL, + }, + }, + }, + ], +}) +``` + +You pass the options that you defined in the `MagentoModuleService`. Make sure to also set their environment variables in the `.env` file: + +```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: + +- `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. + +Medusa supports integrating third-party services, such as [S3](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/architectural-modules/file/s3/index.html.md), in a File Module Provider. Refer to the [File Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/architectural-modules/file/index.html.md) documentation to find other module providers and how to create a custom provider. + +You can now use the Magento Module to migrate data, which you'll do in the next steps. + +*** + +## Step 5: Build Product Migration Workflow + +In this section, you'll add the feature to migrate products from Magento to Medusa. To implement this feature, you'll use a workflow. + +A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an API route or a scheduled job. + +By implementing the migration feature in a workflow, you ensure that the data remains consistent and that the migration process can be rolled back if an error occurs. + +Refer to the [Workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) documentation to learn more about workflows. + +### Workflow Steps + +The workflow you'll create will have the following steps: + +- [getMagentoProductsStep](#getMagentoProductsStep): Retrieve products from Magento using the Magento Module. +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve Medusa store details, which you'll need when creating the products. +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve a shipping profile, which you'll associate the created products with. +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve Magento products that are already in Medusa to update them, instead of creating them. +- [createProductsWorkflow](https://docs.medusajs.com/references/medusa-workflows/createProductsWorkflow/index.html.md): Create products in the Medusa application. +- [updateProductsWorkflow](https://docs.medusajs.com/references/medusa-workflows/updateProductsWorkflow/index.html.md): Update existing products in the Medusa application. + +You only need to implement the `getMagentoProductsStep` step, which retrieves the products from Magento. The other steps and workflows are provided by Medusa's `@medusajs/medusa/core-flows` package. + +### getMagentoProductsStep + +The first step of the workflow retrieves and returns the products from Magento. + +In your plugin, create the file `src/workflows/steps/get-magento-products.ts` with the following content: + +![Diagram showcasing the get-magento-products file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739349590/Medusa%20Resources/magento-5_ueb4wn.jpg) + +```ts title="src/workflows/steps/get-magento-products.ts" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { MAGENTO_MODULE } from "../../modules/magento" +import MagentoModuleService from "../../modules/magento/service" + +type GetMagentoProductsInput = { + currentPage: number + pageSize: number +} + +export const getMagentoProductsStep = createStep( + "get-magento-products", + async ({ currentPage, pageSize }: GetMagentoProductsInput, { container }) => { + const magentoModuleService: MagentoModuleService = + container.resolve(MAGENTO_MODULE) + + const response = await magentoModuleService.getProducts({ + currentPage, + pageSize, + }) + + return new StepResponse(response) + } +) +``` + +You create a step using `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's name, which is `get-magento-products`. +2. An async function that executes the step's logic. The function receives two parameters: + - The input data for the step, which in this case is the pagination parameters. + - An object holding the workflow's context, including the [Medusa Container](https://docs.medusajs.com/docslearn/fundamentals/medusa-container/index.html.md) that allows you to resolve Framework and commerce tools. + +In the step function, you resolve the Magento Module's service from the container, then use its `getProducts` method to retrieve the products from Magento. + +Steps that return data must return them in a `StepResponse` instance. The `StepResponse` constructor accepts as a parameter the data to return. + +### Create migrateProductsFromMagentoWorkflow + +You'll now create the workflow that migrates products from Magento using the step you created and steps from Medusa's `@medusajs/medusa/core-flows` package. + +In your plugin, create the file `src/workflows/migrate-products-from-magento.ts` with the following content: + +![Diagram showcasing the migrate-products-from-magento file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739349820/Medusa%20Resources/magento-6_jjdaxj.jpg) + +```ts title="src/workflows/migrate-products-from-magento.ts" +import { + createWorkflow, transform, WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" +import { + CreateProductWorkflowInputDTO, UpsertProductDTO, +} from "@medusajs/framework/types" +import { + createProductsWorkflow, + updateProductsWorkflow, + useQueryGraphStep, +} from "@medusajs/medusa/core-flows" +import { getMagentoProductsStep } from "./steps/get-magento-products" + +type MigrateProductsFromMagentoWorkflowInput = { + currentPage: number + pageSize: number +} + +export const migrateProductsFromMagentoWorkflowId = + "migrate-products-from-magento" + +export const migrateProductsFromMagentoWorkflow = createWorkflow( + { + name: migrateProductsFromMagentoWorkflowId, + retentionTime: 10000, + store: true, + }, + (input: MigrateProductsFromMagentoWorkflowInput) => { + const { pagination, products, attributes } = getMagentoProductsStep( + input + ) + // TODO prepare data to create and update products + } +) +``` + +You create a workflow using `createWorkflow` from the Workflows SDK. It accepts two parameters: + +1. An object with the workflow's configuration, including the name and whether to store the workflow's executions. You enable storing the workflow execution so that you can view it later in the Medusa Admin dashboard. +2. A worflow constructor function, which holds the workflow's implementation. The function receives the input data for the workflow, which is the pagination parameters. + +In the workflow constructor function, you use the `getMagentoProductsStep` step to retrieve the products from Magento, passing it the pagination parameters from the workflow's input. + +Next, you'll retrieve the Medusa store details and shipping profiles. These are necessary to prepare the data of the products to create or update. + +Replace the `TODO` in the workflow function with the following: + +```ts title="src/workflows/migrate-products-from-magento.ts" +const { data: stores } = useQueryGraphStep({ + entity: "store", + fields: ["supported_currencies.*", "default_sales_channel_id"], + pagination: { + take: 1, + skip: 0, + }, +}) + +const { data: shippingProfiles } = useQueryGraphStep({ + entity: "shipping_profile", + fields: ["id"], + pagination: { + take: 1, + skip: 0, + }, +}).config({ name: "get-shipping-profiles" }) + +// TODO retrieve existing products +``` + +You use the `useQueryGraphStep` step to retrieve the store details and shipping profiles. `useQueryGraphStep` is a Medusa step that wraps [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), allowing you to use it in a workflow. Query is a tool that retrieves data across modules. + +Whe retrieving the store details, you specifically retrieve its supported currencies and default sales channel ID. You'll associate the products with the store's default sales channel, and set their variant prices in the supported currencies. You'll also associate the products with a shipping profile. + +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: + +```ts title="src/workflows/migrate-products-from-magento.ts" +const externalIdFilters = transform({ + products, +}, (data) => { + return data.products.map((product) => product.id.toString()) +}) + +const { data: existingProducts } = useQueryGraphStep({ + entity: "product", + fields: ["id", "external_id", "variants.id", "variants.metadata"], + filters: { + external_id: externalIdFilters, + }, +}).config({ name: "get-existing-products" }) + +// TODO prepare products to create or update +``` + +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. + +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. + +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: + +- 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. + +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 ?

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 * * *", +} +``` + +A scheduled job file must export: + +- 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. + +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. + +Based on the job's configurations, the Medusa application will run the job at midnight every day. + +### Test it Out + +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 +``` + +After a minute, you'll see a message in the terminal indicating that the migration started: + +```plain title="Terminal" +info: Migrating products from Magento... +``` + +Once the migration is done, you'll see the following message: + +```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. Then, click on Products in the sidebar. You'll see your magento products in the list of products. + +![Click on products at the sidebar on the right, then view the products in the table in the middle.](https://res.cloudinary.com/dza7lstvk/image/upload/v1739359394/Medusa%20Resources/Screenshot_2025-02-12_at_1.22.44_PM_uva98i.png) + +*** + +## Next Steps + +You've now implemented the logic to migrate products from Magento to Medusa.

The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md).

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 Notification Module delegates sending notifications to other modules, called module providers. In this step, you'll create a Resend Module Provider that implements sending notifications through the email channel. In later steps, you'll send email notifications with Resend when an order is placed through this provider. + +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/resend`. + +### 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 Resend Module Provider's service and the methods necessary to send an email with Resend. + +Start by creating the file `src/modules/resend/service.ts` with the following content: + +```ts title="src/modules/resend/service.ts" highlights={serviceHighlights1} +import { + AbstractNotificationProviderService, +} from "@medusajs/framework/utils" +import { + Logger, +} from "@medusajs/framework/types" +import { + Resend, +} from "resend" + +type ResendOptions = { + api_key: string + from: string + html_templates?: Record +} + +class ResendNotificationProviderService extends AbstractNotificationProviderService { + static identifier = "notification-resend" + private resendClient: Resend + private options: ResendOptions + private logger: Logger + + // ... +} + +export default ResendNotificationProviderService +``` + +A Notification Module Provider's service must extend the `AbstractNotificationProviderService`. It has a `send` method that you'll implement soon. The service must also have an `identifier` static property, which is a unique identifier that the Medusa application will use to register the provider in the database. + +The `ResendNotificationProviderService` class also has the following properties: + +- `resendClient` of type `Resend` (from the Resend SDK you installed in the previous step) to send emails through Resend. +- `options` of type `ResendOptions`. Modules accept options through Medusa's configurations. This ensures that the module is reusable across applications and you don't use sensitive variables like API keys directly in your code. The options that the Resend Module Provider accepts are: + - `api_key`: The Resend API key. + - `from`: The email address to send the emails from. + - `html_templates`: An optional object to replace the default subject and template that the Resend Module uses. This is also useful to support custom emails in different Medusa application setups. +- `logger` property, which is an instance of Medusa's [Logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md), to log messages. + +To send requests using the `resendClient`, you need to initialize it in the class's constructor. So, add the following constructor to `ResendNotificationProviderService`: + +```ts title="src/modules/resend/service.ts" +// ... + +type InjectedDependencies = { + logger: Logger +} + +class ResendNotificationProviderService extends AbstractNotificationProviderService { + // ... + constructor( + { logger }: InjectedDependencies, + options: ResendOptions + ) { + super() + this.resendClient = new Resend(options.api_key) + this.options = options + this.logger = logger + } +} +``` + +A module's service accepts two parameters: + +1. Dependencies resolved from the [Module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md), which is the module's local registry that the Medusa application adds Framework tools to. In this service, you resolve the [Logger utility](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) from the module's container. +2. The module's options that are passed to the module in Medusa's configuration as you'll see in a later section. + +Using the API key passed in the module's options, you initialize the Resend client. You also set the `options` and `logger` properties. + +#### Validate Options Method + +A Notification Module Provider's service can implement a static `validateOptions` method that ensures the options passed to the module through Medusa's configurations are valid. + +So, add to the `ResendNotificationProviderService` the `validateOptions` method: + +```ts title="src/modules/resend/service.ts" +// other imports... +import { + // other imports... + MedusaError, +} from "@medusajs/framework/utils" + +// ... + +class ResendNotificationProviderService extends AbstractNotificationProviderService { + // ... + static validateOptions(options: Record) { + if (!options.api_key) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Option `api_key` is required in the provider's options." + ) + } + if (!options.from) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Option `from` is required in the provider's options." + ) + } + } +} +``` + +In the `validateOptions` method, you throw an error if the `api_key` or `from` options aren't passed to the module. To throw errors, you use `MedusaError` from the Modules SDK. This ensures errors follow Medusa's conventions and are displayed similar to Medusa's errors. + +#### Implement Template Methods + +Each email type has a different template and content. For example, order confirmation emails show the order's details, whereas customer confirmation emails show a greeting message to the customer. + +So, add two methods to the `ResendNotificationProviderService` class that retrieve the email template and subject of a specified template type: + +```ts title="src/modules/resend/service.ts" highlights={serviceHighlights2} +// imports and types... + +enum Templates { + ORDER_PLACED = "order-placed", +} + +const templates: {[key in Templates]?: (props: unknown) => React.ReactNode} = { + // TODO add templates +} + +class ResendNotificationProviderService extends AbstractNotificationProviderService { + // ... + getTemplate(template: Templates) { + if (this.options.html_templates?.[template]) { + return this.options.html_templates[template].content + } + const allowedTemplates = Object.keys(templates) + + if (!allowedTemplates.includes(template)) { + return null + } + + return templates[template] + } + + getTemplateSubject(template: Templates) { + if (this.options.html_templates?.[template]?.subject) { + return this.options.html_templates[template].subject + } + switch(template) { + case Templates.ORDER_PLACED: + return "Order Confirmation" + default: + return "New Email" + } + } +} +``` + +You first define a `Templates` enum, which holds the names of supported template types. You can add more template types to this enum later. You also define a `templates` variable that specifies the React template for each template type. You'll add templates to this variable later. + +In the `ResendNotificationProviderService` you add two methods: + +- `getTemplate`: Retrieve the template of a template type. If the `html_templates` option is set for the specified template type, you return its `content`'s value. Otherwise, you retrieve the template from the `templates` variable. +- `getTemplateSubject`: Retrieve the subject of a template type. If a `subject` is passed for the template type in the `html_templates`, you return its value. Otherwise, you return a subject based on the template type. + +You'll use these methods in the `send` method next. + +#### Implement Send Method + +In this section, you'll implement the `send` method of `ResendNotificationProviderService`. When you send a notification through the email channel later using the Notification Module, the Notification Module's service will use this `send` method under the hood to send the email with Resend. + +In the `send` method, you'll retrieve the template and subject of the email template, then send the email using the Resend client. + +Add the `send` method to the `ResendNotificationProviderService` class: + +```ts title="src/modules/resend/service.ts" highlights={serviceHighlights3} +// other imports... +import { + // ... + ProviderSendNotificationDTO, + ProviderSendNotificationResultsDTO, +} from "@medusajs/framework/types" +import { + // ... + CreateEmailOptions, +} from "resend" + +class ResendNotificationProviderService extends AbstractNotificationProviderService { + // ... + async send( + notification: ProviderSendNotificationDTO + ): Promise { + const template = this.getTemplate(notification.template as Templates) + + if (!template) { + this.logger.error(`Couldn't find an email template for ${notification.template}. The valid options are ${Object.values(Templates)}`) + return {} + } + + const emailOptions: CreateEmailOptions = { + from: this.options.from, + to: [notification.to], + subject: this.getTemplateSubject(notification.template as Templates), + html: "", + } + + if (typeof template === "string") { + emailOptions.html = template + } else { + emailOptions.react = template(notification.data) + delete emailOptions.html + } + + const { data, error } = await this.resendClient.emails.send(emailOptions) + + if (error) { + this.logger.error(`Failed to send email`, error) + return {} + } + + return { id: data.id } + } +} +``` + +The `send` method receives the notification details object as a parameter. Some of its properties include: + +- `to`: The address to send the notification to. +- `template`: The template type of the notification. +- `data`: The data useful for the email type. For example, when sending an order-confirmation email, `data` would hold the order's details. + +In the method, you retrieve the template and subject of the email using the methods you defined earlier. Then, you put together the data to pass to Resend, such as the email address to send the notification to and the email address to send from. Also, if the email's template is a string, it's passed as an HTML template. Otherwise, it's passed as a React template. + +Finally, you use the `emails.send` method of the Resend client to send the email. If an error occurs you log it in the terminal. Otherwise, you return the ID of the send email as received from Resend. Medusa uses this ID when creating the notification in its database. + +### Export Module Definition + +The `ResendNotificationProviderService` class now has the methods necessary to start sending emails. + +Next, you must export the module provider's definition, which lets Medusa know what module this provider belongs to and its service. + +Create the file `src/modules/resend/index.ts` with the following content: + +```ts title="src/modules/resend/index.ts" +import { + ModuleProvider, + Modules, +} from "@medusajs/framework/utils" +import ResendNotificationProviderService from "./service" + +export default ModuleProvider(Modules.NOTIFICATION, { + services: [ResendNotificationProviderService], +}) +``` + +You export the module provider's definition using `ModuleProvider` from the Modules SDK. It accepts as a first parameter the name of the module that this provider belongs to, which is the Notification Module. It also accepts as a second parameter an object having a `service` property indicating the provider's service. + +### Add Module to Configurations + +Finally, to register modules and module providers in Medusa, you must add them to Medusa's configurations. + +Medusa's configurations are set in the `medusa-config.ts` file, which is at the root directory of your Medusa application. The configuration object accepts a `modules` array, whose value is an array of modules to add to the application. + +Add the `modules` property to the exported configurations in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + { + resolve: "./src/modules/resend", + id: "resend", + options: { + channels: ["email"], + api_key: process.env.RESEND_API_KEY, + from: process.env.RESEND_FROM_EMAIL, + }, + }, + ], + }, + }, + ], +}) +``` + +In the `modules` array, you pass a module object having the following properties: + +- `resolve`: The NPM package of the Notification Module. Since the Resend Module is a Notification Module Provider, it'll be passed in the options of the Notification Module. +- `options`: An object of options to pass to the module. It has a `providers` property which is an array of module providers to register. Each module provider object has the following properties: + - `resolve`: The path to the module provider to register in the application. It can also be the name of an NPM package. + - `id`: A unique ID, which Medusa will use along with the `identifier` static property that you set earlier in the class to identify this module provider. + - `options`: An object of options to pass to the module provider. These are the options you expect and use in the module provider's service. You must also specify the `channels` option, which indicates the channels that this provider sends notifications through. + +Some of the module's options, such as the Resend API key, are set in environment variables. So, add the following environment variables to `.env`: + +```shell +RESEND_FROM_EMAIL=onboarding@resend.dev +RESEND_API_KEY= +``` + +Where: + +- `RESEND_FROM_EMAIL`: The email to send emails from. If you've configured the custom domain as explained in [Step 2](#step-2-prepare-resend-account), change this email to an email from your custom domain. Otherwise, you can use `onboarding@resend.dev` for development purposes. +- `RESEND_API_KEY` is the API key of your Resend account.

You'll test it out in a later section. + +*** + +## Step 5: Add Order Confirmation Template + +In this step, you'll add a React template for order confirmation emails. You'll create it using the [react-email](https://github.com/resend/react-email) package you installed earlier. You can follow the same steps for other email templates, such as for customer confirmation. + +Create the directory `src/modules/resend/emails` that will hold the email templates. Then, to add the template for order confirmation, create the file `src/modules/resend/emails/order-placed.tsx` with the following content: + +```tsx title="src/modules/resend/emails/order-placed.tsx" highlights={templateHighlights} +import { Text, Column, Container, Heading, Html, Img, Row, Section } from "@react-email/components" +import { BigNumberValue, OrderDTO } from "@medusajs/framework/types" + +type OrderPlacedEmailProps = { + order: OrderDTO +} + +function OrderPlacedEmailComponent({ order }: OrderPlacedEmailProps) { + const formatter = new Intl.NumberFormat([], { + style: "currency", + currencyDisplay: "narrowSymbol", + currency: order.currency_code, + }) + + const formatPrice = (price: BigNumberValue) => { + if (typeof price === "number") { + return formatter.format(price) + } + + if (typeof price === "string") { + return formatter.format(parseFloat(price)) + } + + return price?.toString() || "" + } + + return ( + + Thank you for your order + {order.email}'s Items + + {order.items.map((item) => { + return ( +
+ + + {item.product_title} + + + + {item.product_title} + + {item.variant_title} + {formatPrice(item.total)} + + +
+ ) + })} + + + ) +} + +export const orderPlacedEmail = (props: OrderPlacedEmailProps) => ( + +) +``` + +You define the `OrderPlacedEmailComponent` which is a React email template that shows the order's details, such as items and their totals. The component accepts an `order` object as a prop. + +You also export an `orderPlacedEmail` function, which accepts props as an input and returns the `OrderPlacedEmailComponent` passing it the props. Because you can't use JSX syntax in `src/modules/resend/service.ts`, you'll import this function instead. + +Next, update the `templates` variable in `src/modules/resend/service.ts` to assign this template to the `order-placed` template type: + +```ts title="src/modules/resend/service.ts" +// other imports... +import { orderPlacedEmail } from "./emails/order-placed" + +const templates: {[key in Templates]?: (props: unknown) => React.ReactNode} = { + [Templates.ORDER_PLACED]: orderPlacedEmail, +} +``` + +The `ResendNotificationProviderService` will now use the `OrderPlacedEmailComponent` as the template of order confirmation emails. + +*** + +## Step 6: Send Email when Order is Placed + +Medusa has an event system that emits an event when a commerce operation is performed. You can then listen and handle that event in an asynchronous function called a subscriber. + +So, to send a confirmation email when a customer places an order, which is a commerce operation that Medusa already implements, you don't need to extend or hack your way into Medusa's implementation as you would do with other commerce platforms. + +Instead, you'll create a subscriber that listens to the `order.placed` event and sends an email when the event is emitted. + +Learn more about Medusa's event system in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). + +### Send Order Confirmation Email Workflow + +To send the order confirmation email, you need to retrieve the order's details first, then use the Notification Module's service to send the email. To implement this flow, you'll create a workflow. + +A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in a subscriber. + +Learn more about workflows in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) + +#### Send Notification Step + +You'll start by implementing the step of the workflow that sends the notification. To do that, create the file `src/workflows/steps/send-notification.ts` with the following content: + +```ts title="src/workflows/steps/send-notification.ts" +import { Modules } from "@medusajs/framework/utils" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { CreateNotificationDTO } from "@medusajs/framework/types" + +export const sendNotificationStep = createStep( + "send-notification", + async (data: CreateNotificationDTO[], { container }) => { + const notificationModuleService = container.resolve( + Modules.NOTIFICATION + ) + const notification = await notificationModuleService.createNotifications(data) + return new StepResponse(notification) + } +) +``` + +You define the `sendNotificationStep` using the `createStep` function that accepts two parameters: + +- A string indicating the step's unique name. +- The step's function definition as a second parameter. It accepts the step's input as a first parameter, and an object of options as a second. + +The `container` property in the second parameter is an instance of the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools, such as a module's service, that you can resolve to utilize their functionalities. + +The Medusa container is accessible by all customizations, such as workflows and subscribers, except for modules. Each module has its own container with Framework tools like the Logger utility. + +In the step function, you resolve the Notification Module's service, and use its `createNotifications` method, passing it the notification's data that the step receives as an input. + +The step returns an instance of `StepResponse`, which must be returned by any step. It accepts as a parameter the data to return to the workflow that executed this step. + +#### Workflow Implementation + +You'll now create the workflow that uses the `sendNotificationStep` to send the order confirmation email. + +Create the file `src/workflows/send-order-confirmation.ts` with the following content: + +```ts title="src/workflows/send-order-confirmation.ts" highlights={workflowHighlights} +import { + createWorkflow, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" +import { useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { sendNotificationStep } from "./steps/send-notification" + +type WorkflowInput = { + id: string +} + +export const sendOrderConfirmationWorkflow = createWorkflow( + "send-order-confirmation", + ({ id }: WorkflowInput) => { + // @ts-ignore + const { data: orders } = useQueryGraphStep({ + entity: "order", + fields: [ + "id", + "email", + "currency_code", + "total", + "items.*", + ], + filters: { + id, + }, + }) + + const notification = sendNotificationStep([{ + to: orders[0].email, + channel: "email", + template: "order-placed", + data: { + order: orders[0], + }, + }]) + + return new WorkflowResponse(notification) + } +) +``` + +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 workflow has the following steps: + +1. `useQueryGraphStep`, which is a step implemented by Medusa that uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), a tool that allows you to retrieve data across modules. You use it to retrieve the order's details. +2. `sendNotificationStep` which is the step you implemented. You pass it an array with one object, which is the notification's details having following properties: + - `to`: The address to send the email to. You pass the customer's email that is stored in the order. + - `channel`: The channel to send the notification through, which is `email`. Since you specified `email` in the Resend Module Provider's `channel` option, the Notification Module will delegate the sending to the Resend Module Provider's service. + - `template`: The email's template type. You retrieve the template content in the `ResendNotificationProviderService`'s `send` method based on the template specified here. + - `data`: The data to pass to the email template, which is the order's details. + +A workflow's constructor function has some constraints in implementation. Learn more about them in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). + +You'll execute the workflow when you create the subscriber next. + +#### Add the Order Placed Subscriber + +Now that you have the workflow to send an order-confirmation email, you'll execute it in a subscriber that's executed whenever an order is placed. + +You create a subscriber in a TypeScript or JavaScript file under the `src/subscribers` directory. So, create the file `src/subscribers/order-placed.ts` with the following content: + +```ts title="src/subscribers/order-placed.ts" highlights={subscriberHighlights} +import type { + SubscriberArgs, + SubscriberConfig, +} from "@medusajs/framework" +import { sendOrderConfirmationWorkflow } from "../workflows/send-order-confirmation" + +export default async function orderPlacedHandler({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await sendOrderConfirmationWorkflow(container) + .run({ + input: { + id: data.id, + }, + }) +} + +export const config: SubscriberConfig = { + event: "order.placed", +} +``` + +A subscriber file exports: + +- An asynchronous function that's executed whenever the associated event is emitted, which is the `order.placed` event. +- A configuration object with an `event` property indicating the event the subscriber is listening to. + +The subscriber function accepts the event's details as a first paramter which has a `data` property that holds the data payload of the event. For example, Medusa emits the `order.placed` event with the order's ID in the data payload. The function also accepts as a second parameter the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). + +In the function, you execute the `sendOrderConfirmationWorkflow` by invoking it, passing it the `container`, then using its `run` method. The `run` method accepts an object having an `input` property, which is the input to pass to the workflow. You pass the ID of the placed order as received in the event's data payload. + +This subscriber now runs whenever an order is placed. You'll see this in action in the next section. + +*** + +## Test it Out: Place an Order + +To test out the Resend integration, you'll place an order using the [Next.js storefront](https://docs.medusajs.com/docs/learn/storefront-development/nextjs-starter/index.html.md) that you installed as part of installing Medusa. + +Start your Medusa application first: + +```bash npm2yarn +npm run dev +``` + +Then, in the Next.js storefront's directory (which was installed in a directory outside of the Medusa application's directory with the name `{project-name}-storefront`, where `{project-name}` is the name of the Medusa application's directory), run the following command to start the storefront: + +```bash npm2yarn +npm run dev +``` + +Then, open the storefront in your browser at `http://localhost:8000` and: + +1.

Then, when you're asked whether you want to install the Next.js storefront, choose `Y` for yes. - -Afterwards, the installation process will start, which will install the Medusa application in a directory with your project's name, and the Next.js storefront in a directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more about Medusa's architecture in [this documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user.

[react-email](https://github.com/resend/react-email), which is a package created by Resend to create email templates with React: - -```bash npm2yarn -npm install @react-email/components -E -``` - -You'll use these packages in the next steps. - -*** - -## Step 4: Create Resend Module Provider - -To integrate third-party services into Medusa, you create a custom module. 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 Notification Module delegates sending notifications to other modules, called module providers. In this step, you'll create a Resend Module Provider that implements sending notifications through the email channel. In later steps, you'll send email notifications with Resend when an order is placed through this provider. - -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/resend`. - -### 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 Resend Module Provider's service and the methods necessary to send an email with Resend. - -Start by creating the file `src/modules/resend/service.ts` with the following content: - -```ts title="src/modules/resend/service.ts" highlights={serviceHighlights1} -import { - AbstractNotificationProviderService, -} from "@medusajs/framework/utils" -import { - Logger, -} from "@medusajs/framework/types" -import { - Resend, -} from "resend" - -type ResendOptions = { - api_key: string - from: string - html_templates?: Record -} - -class ResendNotificationProviderService extends AbstractNotificationProviderService { - static identifier = "notification-resend" - private resendClient: Resend - private options: ResendOptions - private logger: Logger - - // ... -} - -export default ResendNotificationProviderService -``` - -A Notification Module Provider's service must extend the `AbstractNotificationProviderService`. It has a `send` method that you'll implement soon. The service must also have an `identifier` static property, which is a unique identifier that the Medusa application will use to register the provider in the database. - -The `ResendNotificationProviderService` class also has the following properties: - -- `resendClient` of type `Resend` (from the Resend SDK you installed in the previous step) to send emails through Resend. -- `options` of type `ResendOptions`. Modules accept options through Medusa's configurations. This ensures that the module is reusable across applications and you don't use sensitive variables like API keys directly in your code. The options that the Resend Module Provider accepts are: - - `api_key`: The Resend API key. - - `from`: The email address to send the emails from. - - `html_templates`: An optional object to replace the default subject and template that the Resend Module uses. This is also useful to support custom emails in different Medusa application setups. -- `logger` property, which is an instance of Medusa's [Logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md), to log messages. - -To send requests using the `resendClient`, you need to initialize it in the class's constructor. So, add the following constructor to `ResendNotificationProviderService`: - -```ts title="src/modules/resend/service.ts" -// ... - -type InjectedDependencies = { - logger: Logger -} - -class ResendNotificationProviderService extends AbstractNotificationProviderService { - // ... - constructor( - { logger }: InjectedDependencies, - options: ResendOptions - ) { - super() - this.resendClient = new Resend(options.api_key) - this.options = options - this.logger = logger - } -} -``` - -A module's service accepts two parameters: - -1. Dependencies resolved from the [Module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md), which is the module's local registry that the Medusa application adds Framework tools to. In this service, you resolve the [Logger utility](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) from the module's container. -2. The module's options that are passed to the module in Medusa's configuration as you'll see in a later section. - -Using the API key passed in the module's options, you initialize the Resend client. You also set the `options` and `logger` properties. - -#### Validate Options Method - -A Notification Module Provider's service can implement a static `validateOptions` method that ensures the options passed to the module through Medusa's configurations are valid. - -So, add to the `ResendNotificationProviderService` the `validateOptions` method: - -```ts title="src/modules/resend/service.ts" -// other imports... -import { - // other imports... - MedusaError, -} from "@medusajs/framework/utils" - -// ... - -class ResendNotificationProviderService extends AbstractNotificationProviderService { - // ... - static validateOptions(options: Record) { - if (!options.api_key) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Option `api_key` is required in the provider's options." - ) - } - if (!options.from) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Option `from` is required in the provider's options." - ) - } - } -} -``` - -In the `validateOptions` method, you throw an error if the `api_key` or `from` options aren't passed to the module. To throw errors, you use `MedusaError` from the Modules SDK. This ensures errors follow Medusa's conventions and are displayed similar to Medusa's errors. - -#### Implement Template Methods - -Each email type has a different template and content. For example, order confirmation emails show the order's details, whereas customer confirmation emails show a greeting message to the customer. - -So, add two methods to the `ResendNotificationProviderService` class that retrieve the email template and subject of a specified template type: - -```ts title="src/modules/resend/service.ts" highlights={serviceHighlights2} -// imports and types... - -enum Templates { - ORDER_PLACED = "order-placed", -} - -const templates: {[key in Templates]?: (props: unknown) => React.ReactNode} = { - // TODO add templates -} - -class ResendNotificationProviderService extends AbstractNotificationProviderService { - // ... - getTemplate(template: Templates) { - if (this.options.html_templates?.[template]) { - return this.options.html_templates[template].content - } - const allowedTemplates = Object.keys(templates) - - if (!allowedTemplates.includes(template)) { - return null - } - - return templates[template] - } - - getTemplateSubject(template: Templates) { - if (this.options.html_templates?.[template]?.subject) { - return this.options.html_templates[template].subject - } - switch(template) { - case Templates.ORDER_PLACED: - return "Order Confirmation" - default: - return "New Email" - } - } -} -``` - -You first define a `Templates` enum, which holds the names of supported template types. You can add more template types to this enum later. You also define a `templates` variable that specifies the React template for each template type. You'll add templates to this variable later. - -In the `ResendNotificationProviderService` you add two methods: - -- `getTemplate`: Retrieve the template of a template type. If the `html_templates` option is set for the specified template type, you return its `content`'s value. Otherwise, you retrieve the template from the `templates` variable. -- `getTemplateSubject`: Retrieve the subject of a template type. If a `subject` is passed for the template type in the `html_templates`, you return its value. Otherwise, you return a subject based on the template type. - -You'll use these methods in the `send` method next. - -#### Implement Send Method - -In this section, you'll implement the `send` method of `ResendNotificationProviderService`. When you send a notification through the email channel later using the Notification Module, the Notification Module's service will use this `send` method under the hood to send the email with Resend. - -In the `send` method, you'll retrieve the template and subject of the email template, then send the email using the Resend client. - -Add the `send` method to the `ResendNotificationProviderService` class: - -```ts title="src/modules/resend/service.ts" highlights={serviceHighlights3} -// other imports... -import { - // ... - ProviderSendNotificationDTO, - ProviderSendNotificationResultsDTO, -} from "@medusajs/framework/types" -import { - // ... - CreateEmailOptions, -} from "resend" - -class ResendNotificationProviderService extends AbstractNotificationProviderService { - // ... - async send( - notification: ProviderSendNotificationDTO - ): Promise { - const template = this.getTemplate(notification.template as Templates) - - if (!template) { - this.logger.error(`Couldn't find an email template for ${notification.template}. The valid options are ${Object.values(Templates)}`) - return {} - } - - const emailOptions: CreateEmailOptions = { - from: this.options.from, - to: [notification.to], - subject: this.getTemplateSubject(notification.template as Templates), - html: "", - } - - if (typeof template === "string") { - emailOptions.html = template - } else { - emailOptions.react = template(notification.data) - delete emailOptions.html - } - - const { data, error } = await this.resendClient.emails.send(emailOptions) - - if (error) { - this.logger.error(`Failed to send email`, error) - return {} - } - - return { id: data.id } - } -} -``` - -The `send` method receives the notification details object as a parameter. Some of its properties include: - -- `to`: The address to send the notification to. -- `template`: The template type of the notification. -- `data`: The data useful for the email type. For example, when sending an order-confirmation email, `data` would hold the order's details. - -In the method, you retrieve the template and subject of the email using the methods you defined earlier. Then, you put together the data to pass to Resend, such as the email address to send the notification to and the email address to send from. Also, if the email's template is a string, it's passed as an HTML template. Otherwise, it's passed as a React template. - -Finally, you use the `emails.send` method of the Resend client to send the email. If an error occurs you log it in the terminal. Otherwise, you return the ID of the send email as received from Resend. Medusa uses this ID when creating the notification in its database. - -### Export Module Definition - -The `ResendNotificationProviderService` class now has the methods necessary to start sending emails. - -Next, you must export the module provider's definition, which lets Medusa know what module this provider belongs to and its service. - -Create the file `src/modules/resend/index.ts` with the following content: - -```ts title="src/modules/resend/index.ts" -import { - ModuleProvider, - Modules, -} from "@medusajs/framework/utils" -import ResendNotificationProviderService from "./service" - -export default ModuleProvider(Modules.NOTIFICATION, { - services: [ResendNotificationProviderService], -}) -``` - -You export the module provider's definition using `ModuleProvider` from the Modules SDK. It accepts as a first parameter the name of the module that this provider belongs to, which is the Notification Module. It also accepts as a second parameter an object having a `service` property indicating the provider's service. - -### Add Module to Configurations - -Finally, to register modules and module providers in Medusa, you must add them to Medusa's configurations. - -Medusa's configurations are set in the `medusa-config.ts` file, which is at the root directory of your Medusa application. The configuration object accepts a `modules` array, whose value is an array of modules to add to the application. - -Add the `modules` property to the exported configurations in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - { - resolve: "./src/modules/resend", - id: "resend", - options: { - channels: ["email"], - api_key: process.env.RESEND_API_KEY, - from: process.env.RESEND_FROM_EMAIL, - }, - }, - ], - }, - }, - ], -}) -``` - -In the `modules` array, you pass a module object having the following properties: - -- `resolve`: The NPM package of the Notification Module. Since the Resend Module is a Notification Module Provider, it'll be passed in the options of the Notification Module. -- `options`: An object of options to pass to the module. It has a `providers` property which is an array of module providers to register. Each module provider object has the following properties: - - `resolve`: The path to the module provider to register in the application. It can also be the name of an NPM package. - - `id`: A unique ID, which Medusa will use along with the `identifier` static property that you set earlier in the class to identify this module provider. - - `options`: An object of options to pass to the module provider. These are the options you expect and use in the module provider's service. You must also specify the `channels` option, which indicates the channels that this provider sends notifications through. - -Some of the module's options, such as the Resend API key, are set in environment variables. So, add the following environment variables to `.env`: - -```shell -RESEND_FROM_EMAIL=onboarding@resend.dev -RESEND_API_KEY= -``` - -Where: - -- `RESEND_FROM_EMAIL`: The email to send emails from. If you've configured the custom domain as explained in [Step 2](#step-2-prepare-resend-account), change this email to an email from your custom domain. Otherwise, you can use `onboarding@resend.dev` for development purposes. -- `RESEND_API_KEY` is the API key of your Resend account. To retrieve it: - - Go to API Keys in the sidebar. - - Click on the Create API Key button. - -![Click on the API keys in the sidebar, then click on the Create API Key button at the top right](https://res.cloudinary.com/dza7lstvk/image/upload/v1732535399/Medusa%20Resources/Screenshot_2024-11-25_at_10.22.25_AM_v4d09s.png) - -- In the form that opens, enter a name for the API key (for example, Medusa). You can keep its permissions to Full Access or change it to Sending Access. Once you're done, click Add. - -![The form to create an API key with fields for the API key's name, permissions, and domain](https://res.cloudinary.com/dza7lstvk/image/upload/v1732535464/Medusa%20Resources/Screenshot_2024-11-25_at_10.23.26_AM_g7gcuc.png) - -- A new pop-up will show with your API key hidden. Copy it before closing the pop-up, since you can't access the key again afterwards. Use its value for the `RESEND_API_KEY` environment variable. - -![Click the copy icon to copy the API key](https://res.cloudinary.com/dza7lstvk/image/upload/v1732535791/Medusa%20Resources/Screenshot_2024-11-25_at_10.23.43_AM_divins.png) - -Your Resend Module Provider is all set up. You'll test it out in a later section. - -*** - -## Step 5: Add Order Confirmation Template - -In this step, you'll add a React template for order confirmation emails. You'll create it using the [react-email](https://github.com/resend/react-email) package you installed earlier. You can follow the same steps for other email templates, such as for customer confirmation. - -Create the directory `src/modules/resend/emails` that will hold the email templates. Then, to add the template for order confirmation, create the file `src/modules/resend/emails/order-placed.tsx` with the following content: - -```tsx title="src/modules/resend/emails/order-placed.tsx" highlights={templateHighlights} -import { Text, Column, Container, Heading, Html, Img, Row, Section } from "@react-email/components" -import { BigNumberValue, OrderDTO } from "@medusajs/framework/types" - -type OrderPlacedEmailProps = { - order: OrderDTO -} - -function OrderPlacedEmailComponent({ order }: OrderPlacedEmailProps) { - const formatter = new Intl.NumberFormat([], { - style: "currency", - currencyDisplay: "narrowSymbol", - currency: order.currency_code, - }) - - const formatPrice = (price: BigNumberValue) => { - if (typeof price === "number") { - return formatter.format(price) - } - - if (typeof price === "string") { - return formatter.format(parseFloat(price)) - } - - return price?.toString() || "" - } - - return ( - - Thank you for your order - {order.email}'s Items - - {order.items.map((item) => { - return ( -
- - - {item.product_title} - - - - {item.product_title} - - {item.variant_title} - {formatPrice(item.total)} - - -
- ) - })} - - - ) -} - -export const orderPlacedEmail = (props: OrderPlacedEmailProps) => ( - -) -``` - -You define the `OrderPlacedEmailComponent` which is a React email template that shows the order's details, such as items and their totals. The component accepts an `order` object as a prop. - -You also export an `orderPlacedEmail` function, which accepts props as an input and returns the `OrderPlacedEmailComponent` passing it the props. Because you can't use JSX syntax in `src/modules/resend/service.ts`, you'll import this function instead. - -Next, update the `templates` variable in `src/modules/resend/service.ts` to assign this template to the `order-placed` template type: - -```ts title="src/modules/resend/service.ts" -// other imports... -import { orderPlacedEmail } from "./emails/order-placed" - -const templates: {[key in Templates]?: (props: unknown) => React.ReactNode} = { - [Templates.ORDER_PLACED]: orderPlacedEmail, -} -``` - -The `ResendNotificationProviderService` will now use the `OrderPlacedEmailComponent` as the template of order confirmation emails. - -*** - -## Step 6: Send Email when Order is Placed - -Medusa has an event system that emits an event when a commerce operation is performed. You can then listen and handle that event in an asynchronous function called a subscriber. - -So, to send a confirmation email when a customer places an order, which is a commerce operation that Medusa already implements, you don't need to extend or hack your way into Medusa's implementation as you would do with other commerce platforms. - -Instead, you'll create a subscriber that listens to the `order.placed` event and sends an email when the event is emitted. - -Learn more about Medusa's event system in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). - -### Send Order Confirmation Email Workflow - -To send the order confirmation email, you need to retrieve the order's details first, then use the Notification Module's service to send the email. To implement this flow, you'll create a workflow. - -A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in a subscriber. - -Learn more about workflows in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) - -#### Send Notification Step - -You'll start by implementing the step of the workflow that sends the notification. To do that, create the file `src/workflows/steps/send-notification.ts` with the following content: - -```ts title="src/workflows/steps/send-notification.ts" -import { Modules } from "@medusajs/framework/utils" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { CreateNotificationDTO } from "@medusajs/framework/types" - -export const sendNotificationStep = createStep( - "send-notification", - async (data: CreateNotificationDTO[], { container }) => { - const notificationModuleService = container.resolve( - Modules.NOTIFICATION - ) - const notification = await notificationModuleService.createNotifications(data) - return new StepResponse(notification) - } -) -``` - -You define the `sendNotificationStep` using the `createStep` function that accepts two parameters: - -- A string indicating the step's unique name. -- The step's function definition as a second parameter. It accepts the step's input as a first parameter, and an object of options as a second. - -The `container` property in the second parameter is an instance of the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools, such as a module's service, that you can resolve to utilize their functionalities. - -The Medusa container is accessible by all customizations, such as workflows and subscribers, except for modules. Each module has its own container with Framework tools like the Logger utility. - -In the step function, you resolve the Notification Module's service, and use its `createNotifications` method, passing it the notification's data that the step receives as an input. - -The step returns an instance of `StepResponse`, which must be returned by any step. It accepts as a parameter the data to return to the workflow that executed this step. - -#### Workflow Implementation - -You'll now create the workflow that uses the `sendNotificationStep` to send the order confirmation email. - -Create the file `src/workflows/send-order-confirmation.ts` with the following content: - -```ts title="src/workflows/send-order-confirmation.ts" highlights={workflowHighlights} -import { - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" -import { sendNotificationStep } from "./steps/send-notification" - -type WorkflowInput = { - id: string -} - -export const sendOrderConfirmationWorkflow = createWorkflow( - "send-order-confirmation", - ({ id }: WorkflowInput) => { - // @ts-ignore - const { data: orders } = useQueryGraphStep({ - entity: "order", - fields: [ - "id", - "email", - "currency_code", - "total", - "items.*", - ], - filters: { - id, - }, - }) - - const notification = sendNotificationStep([{ - to: orders[0].email, - channel: "email", - template: "order-placed", - data: { - order: orders[0], - }, - }]) - - return new WorkflowResponse(notification) - } -) -``` - -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 workflow has the following steps: - -1. `useQueryGraphStep`, which is a step implemented by Medusa that uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), a tool that allows you to retrieve data across modules. You use it to retrieve the order's details. -2. `sendNotificationStep` which is the step you implemented. You pass it an array with one object, which is the notification's details having following properties: - - `to`: The address to send the email to. You pass the customer's email that is stored in the order. - - `channel`: The channel to send the notification through, which is `email`. Since you specified `email` in the Resend Module Provider's `channel` option, the Notification Module will delegate the sending to the Resend Module Provider's service. - - `template`: The email's template type. You retrieve the template content in the `ResendNotificationProviderService`'s `send` method based on the template specified here. - - `data`: The data to pass to the email template, which is the order's details. - -A workflow's constructor function has some constraints in implementation. Learn more about them in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). - -You'll execute the workflow when you create the subscriber next. - -#### Add the Order Placed Subscriber - -Now that you have the workflow to send an order-confirmation email, you'll execute it in a subscriber that's executed whenever an order is placed. - -You create a subscriber in a TypeScript or JavaScript file under the `src/subscribers` directory. So, create the file `src/subscribers/order-placed.ts` with the following content: - -```ts title="src/subscribers/order-placed.ts" highlights={subscriberHighlights} -import type { - SubscriberArgs, - SubscriberConfig, -} from "@medusajs/framework" -import { sendOrderConfirmationWorkflow } from "../workflows/send-order-confirmation" - -export default async function orderPlacedHandler({ - event: { data }, - container, -}: SubscriberArgs<{ id: string }>) { - await sendOrderConfirmationWorkflow(container) - .run({ - input: { - id: data.id, - }, - }) -} - -export const config: SubscriberConfig = { - event: "order.placed", -} -``` - -A subscriber file exports: - -- An asynchronous function that's executed whenever the associated event is emitted, which is the `order.placed` event. -- A configuration object with an `event` property indicating the event the subscriber is listening to. - -The subscriber function accepts the event's details as a first paramter which has a `data` property that holds the data payload of the event. For example, Medusa emits the `order.placed` event with the order's ID in the data payload. The function also accepts as a second parameter the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). - -In the function, you execute the `sendOrderConfirmationWorkflow` by invoking it, passing it the `container`, then using its `run` method. The `run` method accepts an object having an `input` property, which is the input to pass to the workflow. You pass the ID of the placed order as received in the event's data payload. - -This subscriber now runs whenever an order is placed. You'll see this in action in the next section. - -*** - -## Test it Out: Place an Order - -To test out the Resend integration, you'll place an order using the [Next.js storefront](https://docs.medusajs.com/docs/learn/storefront-development/nextjs-starter/index.html.md) that you installed as part of installing Medusa. - -Start your Medusa application first: - -```bash npm2yarn -npm run dev -``` - -Then, in the Next.js storefront's directory (which was installed in a directory outside of the Medusa application's directory with the name `{project-name}-storefront`, where `{project-name}` is the name of the Medusa application's directory), run the following command to start the storefront: - -```bash npm2yarn -npm run dev -``` - -Then, open the storefront in your browser at `http://localhost:8000` and: - -1.

After entering the shipping address, choose a delivery and payment methods, then click the Place Order button. - -Once the order is placed, you'll find the following message logged in the Medusa application's terminal: - -```bash -info: Processing order.placed which has 1 subscribers -``` - -This indicates that the `order.placed` event was emitted and its subscriber, which you added in the previous step, is executed. - -If you check the inbox of the email address you specified in the shipping address, you'll find a new email with the order's details. - -![Example of order-confirmation email](https://res.cloudinary.com/dza7lstvk/image/upload/v1732551372/Medusa%20Resources/Screenshot_2024-11-25_at_6.15.59_PM_efyuoj.png) - -*** - -## Next Steps - -You've now integrated Medusa with Resend. You can add more templates for other emails, such as customer registration confirmation, user invites, and more. Check out the [Events Reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/events-reference/index.html.md) for a list of all events that the Medusa application emits. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - -# How to Build Magento Data Migration Plugin - -In this tutorial, you'll learn how to build a [plugin](https://docs.medusajs.com/docs/learn/fundamentals/plugins/index.html.md) that migrates data, such as products, from Magento to Medusa. - -Magento is known for its customization capabilities. However, its monolithic architecture imposes limitations on business requirements, often forcing development teams to implement hacky workarounds. Over time, these customizations become challenging to maintain, especially as the business scales, leading to increased technical debt and slower feature delivery. - -Medusa's modular architecture allows you to build a custom digital commerce platform that meets your business requirements without the limitations of a monolithic system. By migrating from Magento to Medusa, you can take advantage of Medusa's modern technology stack to build a scalable and flexible commerce platform that grows with your business. - -By following this tutorial, you'll create a Medusa plugin that migrates data from a Magento server to a Medusa application in minimal time. You can re-use this plugin across multiple Medusa applications, allowing you to adopt Medusa across your projects. - -## Summary - -### Prerequisites - - - -This tutorial will teach you how to: - -- Install and set up a Medusa application project. -- Install and set up a Medusa plugin. -- Implement a Magento Module in the plugin to connect to Magento's APIs and retrieve products. - - This guide will only focus on migrating product data from Magento to Medusa. You can extend the implementation to migrate other data, such as customers, orders, and more. -- Trigger data migration from Magento to Medusa in a scheduled job. - -You can follow this tutorial whether you're new to Medusa or an advanced Medusa developer. - -![Diagram showcasing the flow of migrating data from Magento to Medusa](https://res.cloudinary.com/dza7lstvk/image/upload/v1739360550/Medusa%20Resources/magento-summary_hsewci.jpg) - -[Example Repository](https://github.com/medusajs/examples/tree/main/migrate-from-magento): Find the full code of the guide in this repository. The repository also includes additional features, such as triggering migrations from the Medusa Admin dashboard. - -*** - -## Step 1: Install a Medusa Application - -You'll first install a Medusa application that exposes core commerce features through REST APIs. You'll later install the Magento plugin in this application to test it out. - -### Prerequisites - -- [Node.js v20+](https://nodejs.org/en/download) -- [Git CLI tool](https://git-scm.com/downloads) -- [PostgreSQL](https://www.postgresql.org/download/) - -Start by installing the Medusa application on your machine with the following command: - -```bash -npx create-medusa-app@latest -``` - -You'll be asked for the project's name. You can also optionally choose to install the [Next.js starter storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md). - -Afterward, the installation process will start, which will install the Medusa application in a directory with your project's name. If you chose to install the Next.js starter, it'll be installed in a separate directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Refer to the [Medusa Architecture](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md) documentation to learn more. - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user. Enter the user's credentials and submit the form. Afterward, you can log in with the new user and explore the dashboard. - -Check out the [troubleshooting guides](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/troubleshooting/create-medusa-app-errors/index.html.md) for help. - -*** - -## Step 2: Install a Medusa Plugin Project - -A plugin is a package of reusable Medusa customizations that you can install in any Medusa application. You can add in the plugin [API Routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md), [Workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md), and other customizations, as you'll see in this guide. Afterward, you can test it out locally in a Medusa application, then publish it to npm to install and use it in any Medusa application. - -Refer to the [Plugins](https://docs.medusajs.com/docs/learn/fundamentals/plugins/index.html.md) documentation to learn more about plugins. - -A Medusa plugin is set up in a different project, giving you the flexibility in building and publishing it, while providing you with the tools to test it out locally in a Medusa application. - -To create a new Medusa plugin project, run the following command in a directory different than that of the Medusa application: - -```bash npm2yarn -npx create-medusa-app@latest medusa-plugin-magento --plugin -``` - -Where `medusa-plugin-magento` is the name of the plugin's directory and the name set in the plugin's `package.json`. So, if you wish to publish it to NPM later under a different name, you can change it here in the command or later in `package.json`. - -Once the installation process is done, a new directory named `medusa-plugin-magento` will be created with the plugin project files. - -![Directory structure of a plugin project](https://res.cloudinary.com/dza7lstvk/image/upload/v1737019441/Medusa%20Book/project-dir_q4xtri.jpg) - -*** - -## Step 3: Set up Plugin in Medusa Application - -Before you start your development, you'll set up the plugin in the Medusa application you installed in the first step. This will allow you to test the plugin during your development process. - -In the plugin's directory, run the following command to publish the plugin to the local package registry: - -```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, you'll install the plugin in the Medusa application from the local registry. - -If you've installed your Medusa project before v2.3.1, you must install [yalc](https://github.com/wclr/yalc) as a development dependency first. - -Run the following command in the Medusa application's directory to install the plugin: - -```bash title="Medusa application" -npx medusa plugin:add medusa-plugin-magento -``` - -This command installs the plugin in the Medusa application from the local package registry. - -Next, register the plugin in the `medusa-config.ts` file of the Medusa application: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "medusa-plugin-magento", - options: { - // TODO add options - }, - }, - ], -}) -``` - -You add the plugin to the array of plugins. Later, you'll pass options useful to retrieve data from Magento. - -Finally, to ensure your plugin's changes are constantly published to the local registry, simplifying your testing process, keep the following command running in the plugin project during development: - -```bash title="Plugin project" -npx medusa plugin:develop -``` - -*** - -## Step 4: Implement Magento Module - -To connect to external applications in Medusa, you create a custom module. 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 Magento Module in the Magento plugin that connects to a Magento server's REST APIs and retrieves data, such as products. - -Refer to the [Modules](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) documentation to learn more about modules. - -### Create Module Directory - -A module is created under the `src/modules` directory of your plugin. So, create the directory `src/modules/magento`. - -![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739272368/magento-1_ikev4x.jpg) - -### Create Module's 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 external systems or the database, which is useful if your module defines tables in the database. - -In this section, you'll create the Magento Module's service that connects to Magento's REST APIs and retrieves data. - -Start by creating the file `src/modules/magento/service.ts` in the plugin with the following content: - -![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739272483/magento-2_ajetpr.jpg) - -```ts title="src/modules/magento/service.ts" -type Options = { - baseUrl: string - storeCode?: string - username: string - password: string - migrationOptions?: { - imageBaseUrl?: string - } -} - -export default class MagentoModuleService { - private options: Options - - constructor({}, options: Options) { - this.options = { - ...options, - storeCode: options.storeCode || "default", - } - } -} -``` - -You create a `MagentoModuleService` that has an `options` property to store the module's options. These options include: - -- `baseUrl`: The base URL of the Magento server. -- `storeCode`: The store code of the Magento store, which is `default` by default. -- `username`: The username of a Magento admin user to authenticate with the Magento server. -- `password`: The password of the Magento admin user. -- `migrationOptions`: Additional options useful for migrating data, such as the base URL to use for product images. - -The service's constructor accepts as a first parameter the [Module Container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md), which allows you to access resources available for the module. 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 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. - -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. - -Lastly, add an `isAccessTokenExpired` method that checks if the access token has expired: - -```ts title="src/modules/magento/service.ts" -export default class MagentoModuleService { - // ... - async isAccessTokenExpired(): Promise { - return !this.accessToken || this.accessToken.expiresAt < new Date() - } -} -``` - -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. - -### Retrieve Products from Magento - -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. - -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: - -![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/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() - } - - // 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 `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/magento/index.ts` with the following content: - -![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 MagentoModuleService from "./service" - -export const MAGENTO_MODULE = "magento" - -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 `magento`. -2. An object with a required property `service` indicating the module's service. - -You'll later use the module's service to retrieve products from Magento. - -### Pass Options to Plugin - -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. - -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({ - // ... - plugins: [ - { - resolve: "medusa-plugin-magento", - options: { - baseUrl: process.env.MAGENTO_BASE_URL, - username: process.env.MAGENTO_USERNAME, - password: process.env.MAGENTO_PASSWORD, - migrationOptions: { - imageBaseUrl: process.env.MAGENTO_IMAGE_BASE_URL, - }, - }, - }, - ], -}) -``` - -You pass the options that you defined in the `MagentoModuleService`. Make sure to also set their environment variables in the `.env` file: - -```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: - -- `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. - -Medusa supports integrating third-party services, such as [S3](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/architectural-modules/file/s3/index.html.md), in a File Module Provider. Refer to the [File Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/architectural-modules/file/index.html.md) documentation to find other module providers and how to create a custom provider. - -You can now use the Magento Module to migrate data, which you'll do in the next steps. - -*** - -## Step 5: Build Product Migration Workflow - -In this section, you'll add the feature to migrate products from Magento to Medusa. To implement this feature, you'll use a workflow. - -A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an API route or a scheduled job. - -By implementing the migration feature in a workflow, you ensure that the data remains consistent and that the migration process can be rolled back if an error occurs. - -Refer to the [Workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) documentation to learn more about workflows. - -### Workflow Steps - -The workflow you'll create will have the following steps: - -- [getMagentoProductsStep](#getMagentoProductsStep): Retrieve products from Magento using the Magento Module. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve Medusa store details, which you'll need when creating the products. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve a shipping profile, which you'll associate the created products with. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve Magento products that are already in Medusa to update them, instead of creating them. -- [createProductsWorkflow](https://docs.medusajs.com/references/medusa-workflows/createProductsWorkflow/index.html.md): Create products in the Medusa application. -- [updateProductsWorkflow](https://docs.medusajs.com/references/medusa-workflows/updateProductsWorkflow/index.html.md): Update existing products in the Medusa application. - -You only need to implement the `getMagentoProductsStep` step, which retrieves the products from Magento. The other steps and workflows are provided by Medusa's `@medusajs/medusa/core-flows` package. - -### getMagentoProductsStep - -The first step of the workflow retrieves and returns the products from Magento. - -In your plugin, create the file `src/workflows/steps/get-magento-products.ts` with the following content: - -![Diagram showcasing the get-magento-products file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739349590/Medusa%20Resources/magento-5_ueb4wn.jpg) - -```ts title="src/workflows/steps/get-magento-products.ts" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { MAGENTO_MODULE } from "../../modules/magento" -import MagentoModuleService from "../../modules/magento/service" - -type GetMagentoProductsInput = { - currentPage: number - pageSize: number -} - -export const getMagentoProductsStep = createStep( - "get-magento-products", - async ({ currentPage, pageSize }: GetMagentoProductsInput, { container }) => { - const magentoModuleService: MagentoModuleService = - container.resolve(MAGENTO_MODULE) - - const response = await magentoModuleService.getProducts({ - currentPage, - pageSize, - }) - - return new StepResponse(response) - } -) -``` - -You create a step using `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's name, which is `get-magento-products`. -2. An async function that executes the step's logic. The function receives two parameters: - - The input data for the step, which in this case is the pagination parameters. - - An object holding the workflow's context, including the [Medusa Container](https://docs.medusajs.com/docslearn/fundamentals/medusa-container/index.html.md) that allows you to resolve Framework and commerce tools. - -In the step function, you resolve the Magento Module's service from the container, then use its `getProducts` method to retrieve the products from Magento. - -Steps that return data must return them in a `StepResponse` instance. The `StepResponse` constructor accepts as a parameter the data to return. - -### Create migrateProductsFromMagentoWorkflow - -You'll now create the workflow that migrates products from Magento using the step you created and steps from Medusa's `@medusajs/medusa/core-flows` package. - -In your plugin, create the file `src/workflows/migrate-products-from-magento.ts` with the following content: - -![Diagram showcasing the migrate-products-from-magento file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1739349820/Medusa%20Resources/magento-6_jjdaxj.jpg) - -```ts title="src/workflows/migrate-products-from-magento.ts" -import { - createWorkflow, transform, WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - CreateProductWorkflowInputDTO, UpsertProductDTO, -} from "@medusajs/framework/types" -import { - createProductsWorkflow, - updateProductsWorkflow, - useQueryGraphStep, -} from "@medusajs/medusa/core-flows" -import { getMagentoProductsStep } from "./steps/get-magento-products" - -type MigrateProductsFromMagentoWorkflowInput = { - currentPage: number - pageSize: number -} - -export const migrateProductsFromMagentoWorkflowId = - "migrate-products-from-magento" - -export const migrateProductsFromMagentoWorkflow = createWorkflow( - { - name: migrateProductsFromMagentoWorkflowId, - retentionTime: 10000, - store: true, - }, - (input: MigrateProductsFromMagentoWorkflowInput) => { - const { pagination, products, attributes } = getMagentoProductsStep( - input - ) - // TODO prepare data to create and update products - } -) -``` - -You create a workflow using `createWorkflow` from the Workflows SDK. It accepts two parameters: - -1. An object with the workflow's configuration, including the name and whether to store the workflow's executions. You enable storing the workflow execution so that you can view it later in the Medusa Admin dashboard. -2. A worflow constructor function, which holds the workflow's implementation. The function receives the input data for the workflow, which is the pagination parameters. - -In the workflow constructor function, you use the `getMagentoProductsStep` step to retrieve the products from Magento, passing it the pagination parameters from the workflow's input. - -Next, you'll retrieve the Medusa store details and shipping profiles. These are necessary to prepare the data of the products to create or update. - -Replace the `TODO` in the workflow function with the following: - -```ts title="src/workflows/migrate-products-from-magento.ts" -const { data: stores } = useQueryGraphStep({ - entity: "store", - fields: ["supported_currencies.*", "default_sales_channel_id"], - pagination: { - take: 1, - skip: 0, - }, -}) - -const { data: shippingProfiles } = useQueryGraphStep({ - entity: "shipping_profile", - fields: ["id"], - pagination: { - take: 1, - skip: 0, - }, -}).config({ name: "get-shipping-profiles" }) - -// TODO retrieve existing products -``` - -You use the `useQueryGraphStep` step to retrieve the store details and shipping profiles. `useQueryGraphStep` is a Medusa step that wraps [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), allowing you to use it in a workflow. Query is a tool that retrieves data across modules. - -Whe retrieving the store details, you specifically retrieve its supported currencies and default sales channel ID. You'll associate the products with the store's default sales channel, and set their variant prices in the supported currencies. You'll also associate the products with a shipping profile. - -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: - -```ts title="src/workflows/migrate-products-from-magento.ts" -const externalIdFilters = transform({ - products, -}, (data) => { - return data.products.map((product) => product.id.toString()) -}) - -const { data: existingProducts } = useQueryGraphStep({ - entity: "product", - fields: ["id", "external_id", "variants.id", "variants.metadata"], - filters: { - external_id: externalIdFilters, - }, -}).config({ name: "get-existing-products" }) - -// TODO prepare products to create or update -``` - -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. - -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. - -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: - -- 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. - -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 ?

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".

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 * * *", -} -``` - -A scheduled job file must export: - -- 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. - -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. - -Based on the job's configurations, the Medusa application will run the job at midnight every day. - -### Test it Out - -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 -``` - -After a minute, you'll see a message in the terminal indicating that the migration started: - -```plain title="Terminal" -info: Migrating products from Magento... -``` - -Once the migration is done, you'll see the following message: - -```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. Then, click on Products in the sidebar. You'll see your magento products in the list of products. - -![Click on products at the sidebar on the right, then view the products in the table in the middle.](https://res.cloudinary.com/dza7lstvk/image/upload/v1739359394/Medusa%20Resources/Screenshot_2025-02-12_at_1.22.44_PM_uva98i.png) - -*** - -## Next Steps - -You've now implemented the logic to migrate products from Magento to Medusa. You can re-use the plugin across Medusa applications. You can also expand on the plugin to: - -- Migrate other entities, such as orders, customers, and categories. Migrating other entities follows the same pattern as migrating products, using workflows and scheduled jobs. You only need to format the data to be migrated as needed. -- Allow triggering migrations from the Medusa Admin dashboard using [Admin Customizations](https://docs.medusajs.com/docs/learn/fundamentals/admin/index.html.md).

To do that, use the `createDataTableColumnHelper` from Medusa UI: - -```tsx title="src/admin/routes/custom/page.tsx" -import { - createDataTableColumnHelper, -} from "@medusajs/ui" -import { - HttpTypes, -} from "@medusajs/framework/types" - -const columnHelper = createDataTableColumnHelper() - -const columns = [ - columnHelper.accessor("title", { - header: "Title", - // Enables sorting for the column. - enableSorting: true, - // If omitted, the header will be used instead if it's a string, - // otherwise the accessor key (id) will be used. - sortLabel: "Title", - // If omitted the default value will be "A-Z" - sortAscLabel: "A-Z", - // If omitted the default value will be "Z-A" - sortDescLabel: "Z-A", - }), - columnHelper.accessor("status", { - header: "Status", - cell: ({ getValue }) => { - const status = getValue() - return ( - - {status === "published" ? "Published" : "Draft"} - - ) - }, - }), -] -``` - -`createDataTableColumnHelper` utility creates a column helper that helps you define the columns for the data table. The column helper has an `accessor` method that accepts two parameters: - -1. The column's key in the table's data. -2. An object with the following properties: - - `header`: The column's header. - - `cell`: (optional) By default, a data's value for a column is displayed as a string. Use this property to specify custom rendering of the value. It accepts a function that returns a string or a React node. The function receives an object that has a `getValue` property function to retrieve the raw value of the cell. - - `enableSorting`: (optional) A boolean that enables sorting data by this column. - - `sortLabel`: (optional) The label for the sorting button. If omitted, the `header` will be used instead if it's a string, otherwise the accessor key (id) will be used. - - `sortAscLabel`: (optional) The label for the ascending sorting button. If omitted, the default value will be "A-Z". - - `sortDescLabel`: (optional) The label for the descending sorting button. If omitted, the default value will be "Z-A". - -Next, you'll define the filters that can be applied to the data table. You'll configure filtering by product status. - -To define the filters, add the following: - -```tsx title="src/admin/routes/custom/page.tsx" -// other imports... -import { - // ... - createDataTableFilterHelper, -} from "@medusajs/ui" - -const filterHelper = createDataTableFilterHelper() - -const filters = [ - filterHelper.accessor("status", { - type: "select", - label: "Status", - options: [ - { - label: "Published", - value: "published", - }, - { - label: "Draft", - value: "draft", - }, - ], - }), -] -``` - -`createDataTableFilterHelper` utility creates a filter helper that helps you define the filters for the data table. The filter helper has an `accessor` method that accepts two parameters: - -1. The key of a column in the table's data. -2. An object with the following properties: - - `type`: The type of filter. It can be either: - - `select`: A select dropdown allowing users to choose multiple values. - - `radio`: A radio button allowing users to choose one value. - - `date`: A date picker allowing users to choose a date. - - `label`: The filter's label. - - `options`: An array of objects with `label` and `value` properties. The `label` is the option's label, and the `value` is the value to filter by. - -You'll now start creating the UI widget's component. Start by adding the necessary state variables: - -```tsx title="src/admin/routes/custom/page.tsx" -// other imports... -import { - // ... - DataTablePaginationState, - DataTableFilteringState, - DataTableSortingState, -} from "@medusajs/ui" -import { useMemo, useState } from "react" - -// ... - -const limit = 15 - -const CustomPage = () => { - const [pagination, setPagination] = useState({ - pageSize: limit, - pageIndex: 0, - }) - const [search, setSearch] = useState("") - const [filtering, setFiltering] = useState({}) - const [sorting, setSorting] = useState(null) - - const offset = useMemo(() => { - return pagination.pageIndex * limit - }, [pagination]) - const statusFilters = useMemo(() => { - return (filtering.status || []) as ProductStatus - }, [filtering]) - - // TODO add data fetching logic -} -``` - -In the component, you've added the following state variables: - -- `pagination`: An object of type `DataTablePaginationState` that holds the pagination state. It has two properties: - - `pageSize`: The number of items to show per page. - - `pageIndex`: The current page index. -- `search`: A string that holds the search query. -- `filtering`: An object of type `DataTableFilteringState` that holds the filtering state. -- `sorting`: An object of type `DataTableSortingState` that holds the sorting state. - -You've also added two memoized variables: - -- `offset`: How many items to skip when fetching data based on the current page. -- `statusFilters`: The selected status filters, if any. - -Next, you'll fetch the products from the Medusa application. Assuming you have the JS SDK configured as explained in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md), add the following imports at the top of the file: - -```tsx title="src/admin/routes/custom/page.tsx" -import { sdk } from "../../lib/config" -import { useQuery } from "@tanstack/react-query" -``` - -This imports the JS SDK instance and `useQuery` from [Tanstack Query](https://tanstack.com/query/latest). - -Then, replace the `TODO` in the component with the following: - -```tsx title="src/admin/routes/custom/page.tsx" -const { data, isLoading } = useQuery({ - queryFn: () => sdk.admin.product.list({ - limit, - offset, - q: search, - status: statusFilters, - order: sorting ? `${sorting.desc ? "-" : ""}${sorting.id}` : undefined, - }), - queryKey: [["products", limit, offset, search, statusFilters, sorting?.id, sorting?.desc]], -}) - -// TODO configure data table -``` - -You use the `useQuery` hook to fetch the products from the Medusa application. In the `queryFn`, you call the `sdk.admin.product.list` method to fetch the products. You pass the following query parameters to the method: - -- `limit`: The number of products to fetch per page. -- `offset`: The number of products to skip based on the current page. -- `q`: The search query, if set. -- `status`: The status filters, if set. -- `order`: The sorting order, if set. - -So, whenever the user changes the current page, search query, status filters, or sorting, the products are fetched based on the new parameters. - -Next, you'll configure the data table. Medusa UI provides a `useDataTable` hook that helps you configure the data table. Add the following imports at the top of the file: - -```tsx title="src/admin/routes/custom/page.tsx" -import { - // ... - useDataTable, -} from "@medusajs/ui" -import { useNavigate } from "react-router-dom" -``` - -Then, replace the `TODO` in the component with the following: - -```tsx title="src/admin/routes/custom/page.tsx" -const navigate = useNavigate() - -const table = useDataTable({ - columns, - data: data?.products || [], - getRowId: (row) => row.id, - rowCount: data?.count || 0, - isLoading, - pagination: { - state: pagination, - onPaginationChange: setPagination, - }, - search: { - state: search, - onSearchChange: setSearch, - }, - filtering: { - state: filtering, - onFilteringChange: setFiltering, - }, - filters, - sorting: { - // Pass the pagination state and updater to the table instance - state: sorting, - onSortingChange: setSorting, - }, - onRowClick: (event, row) => { - // Handle row click, for example - navigate(`/products/${row.id}`) - }, -}) - -// TODO render component -``` - -The `useDataTable` hook accepts an object with the following properties: - -- columns: (\`array\`) The columns to display in the data table. You created this using the \`createDataTableColumnHelper\` utility. -- data: (\`array\`) The products fetched from the Medusa application. -- getRowId: (\`function\`) A function that returns the unique ID of a row. -- rowCount: (\`number\`) The total number of products that can be retrieved. This is used to determine the number of pages. -- isLoading: (\`boolean\`) A boolean that indicates if the data is being fetched. -- pagination: (\`object\`) An object to configure pagination. - - - state: (\`object\`) The pagination React state variable. - - - onPaginationChange: (\`function\`) A function that updates the pagination state. -- search: (\`object\`) An object to configure searching. - - - state: (\`string\`) The search query React state variable. - - - onSearchChange: (\`function\`) A function that updates the search query state. -- filtering: (\`object\`) An object to configure filtering. - - - state: (\`object\`) The filtering React state variable. - - - onFilteringChange: (\`function\`) A function that updates the filtering state. -- filters: (\`array\`) The filters to display in the data table. You created this using the \`createDataTableFilterHelper\` utility. -- sorting: (\`object\`) An object to configure sorting. - - - state: (\`object\`) The sorting React state variable. - - - onSortingChange: (\`function\`) A function that updates the sorting state. -- onRowClick: (\`function\`) A function that allows you to perform an action when the user clicks on a row. In this example, you navigate to the product's detail page. - - - event: (\`mouseevent\`) An instance of the \[MouseClickEvent]\(https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent) object. - - - row: (\`object\`) The data of the row that was clicked. - -Finally, you'll render the data table. But first, add the following imports at the top of the page: - -```tsx title="src/admin/routes/custom/page.tsx" -import { - // ... - DataTable, -} from "@medusajs/ui" -import { SingleColumnLayout } from "../../layouts/single-column" -import { Container } from "../../components/container" -``` - -Aside from the `DataTable` component, you also import the [SingleColumnLayout](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/admin-components/layouts/single-column/index.html.md) and [Container](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/admin-components/components/container/index.html.md) components implemented in other Admin Component guides. These components ensure a style consistent to other pages in the admin dashboard. - -Then, replace the `TODO` in the component with the following: - -```tsx title="src/admin/routes/custom/page.tsx" -return ( - - - - - Products -
- - - -
- - - - - - -) -``` - -You render the `DataTable` component and pass the `table` instance as a prop. In the `DataTable` component, you render a toolbar showing a heading, filter menu, sorting menu, and a search input. You also show pagination after the table. - -Lastly, export the component and the UI widget's configuration at the end of the file: - -```tsx title="src/admin/routes/custom/page.tsx" -// other imports... -import { defineRouteConfig } from "@medusajs/admin-sdk" -import { ChatBubbleLeftRight } from "@medusajs/icons" - -// ... - -export const config = defineRouteConfig({ - label: "Custom", - icon: ChatBubbleLeftRight, -}) - -export default CustomPage -``` - -If you start your Medusa application and go to `localhost:9000/app/custom`, you'll see the data table showing the list of products with pagination, filtering, searching, and sorting functionalities. - -### Full Example Code - -```tsx title="src/admin/routes/custom/page.tsx" -import { defineRouteConfig } from "@medusajs/admin-sdk" -import { ChatBubbleLeftRight } from "@medusajs/icons" -import { - Badge, - createDataTableColumnHelper, - createDataTableFilterHelper, - DataTable, - DataTableFilteringState, - DataTablePaginationState, - DataTableSortingState, - Heading, - useDataTable, -} from "@medusajs/ui" -import { useQuery } from "@tanstack/react-query" -import { SingleColumnLayout } from "../../layouts/single-column" -import { sdk } from "../../lib/config" -import { useMemo, useState } from "react" -import { Container } from "../../components/container" -import { HttpTypes, ProductStatus } from "@medusajs/framework/types" - -const columnHelper = createDataTableColumnHelper() - -const columns = [ - columnHelper.accessor("title", { - header: "Title", - // Enables sorting for the column. - enableSorting: true, - // If omitted, the header will be used instead if it's a string, - // otherwise the accessor key (id) will be used. - sortLabel: "Title", - // If omitted the default value will be "A-Z" - sortAscLabel: "A-Z", - // If omitted the default value will be "Z-A" - sortDescLabel: "Z-A", - }), - columnHelper.accessor("status", { - header: "Status", - cell: ({ getValue }) => { - const status = getValue() - return ( - - {status === "published" ?

To do that, use the `createDataTableColumnHelper` from Medusa UI: + +```tsx title="src/admin/routes/custom/page.tsx" +import { + createDataTableColumnHelper, +} from "@medusajs/ui" +import { + HttpTypes, +} from "@medusajs/framework/types" + +const columnHelper = createDataTableColumnHelper() + +const columns = [ + columnHelper.accessor("title", { + header: "Title", + // Enables sorting for the column. + enableSorting: true, + // If omitted, the header will be used instead if it's a string, + // otherwise the accessor key (id) will be used. + sortLabel: "Title", + // If omitted the default value will be "A-Z" + sortAscLabel: "A-Z", + // If omitted the default value will be "Z-A" + sortDescLabel: "Z-A", + }), + columnHelper.accessor("status", { + header: "Status", + cell: ({ getValue }) => { + const status = getValue() + return ( + + {status === "published" ? "Published" : "Draft"} + + ) + }, + }), +] +``` + +`createDataTableColumnHelper` utility creates a column helper that helps you define the columns for the data table. The column helper has an `accessor` method that accepts two parameters: + +1. The column's key in the table's data. +2. An object with the following properties: + - `header`: The column's header. + - `cell`: (optional) By default, a data's value for a column is displayed as a string. Use this property to specify custom rendering of the value. It accepts a function that returns a string or a React node. The function receives an object that has a `getValue` property function to retrieve the raw value of the cell. + - `enableSorting`: (optional) A boolean that enables sorting data by this column. + - `sortLabel`: (optional) The label for the sorting button. If omitted, the `header` will be used instead if it's a string, otherwise the accessor key (id) will be used. + - `sortAscLabel`: (optional) The label for the ascending sorting button. If omitted, the default value will be "A-Z". + - `sortDescLabel`: (optional) The label for the descending sorting button. If omitted, the default value will be "Z-A". + +Next, you'll define the filters that can be applied to the data table. You'll configure filtering by product status. + +To define the filters, add the following: + +```tsx title="src/admin/routes/custom/page.tsx" +// other imports... +import { + // ... + createDataTableFilterHelper, +} from "@medusajs/ui" + +const filterHelper = createDataTableFilterHelper() + +const filters = [ + filterHelper.accessor("status", { + type: "select", + label: "Status", + options: [ + { + label: "Published", + value: "published", + }, + { + label: "Draft", + value: "draft", + }, + ], + }), +] +``` + +`createDataTableFilterHelper` utility creates a filter helper that helps you define the filters for the data table. The filter helper has an `accessor` method that accepts two parameters: + +1. The key of a column in the table's data. +2. An object with the following properties: + - `type`: The type of filter. It can be either: + - `select`: A select dropdown allowing users to choose multiple values. + - `radio`: A radio button allowing users to choose one value. + - `date`: A date picker allowing users to choose a date. + - `label`: The filter's label. + - `options`: An array of objects with `label` and `value` properties. The `label` is the option's label, and the `value` is the value to filter by. + +You'll now start creating the UI widget's component. Start by adding the necessary state variables: + +```tsx title="src/admin/routes/custom/page.tsx" +// other imports... +import { + // ... + DataTablePaginationState, + DataTableFilteringState, + DataTableSortingState, +} from "@medusajs/ui" +import { useMemo, useState } from "react" + +// ... + +const limit = 15 + +const CustomPage = () => { + const [pagination, setPagination] = useState({ + pageSize: limit, + pageIndex: 0, + }) + const [search, setSearch] = useState("") + const [filtering, setFiltering] = useState({}) + const [sorting, setSorting] = useState(null) + + const offset = useMemo(() => { + return pagination.pageIndex * limit + }, [pagination]) + const statusFilters = useMemo(() => { + return (filtering.status || []) as ProductStatus + }, [filtering]) + + // TODO add data fetching logic +} +``` + +In the component, you've added the following state variables: + +- `pagination`: An object of type `DataTablePaginationState` that holds the pagination state. It has two properties: + - `pageSize`: The number of items to show per page. + - `pageIndex`: The current page index. +- `search`: A string that holds the search query. +- `filtering`: An object of type `DataTableFilteringState` that holds the filtering state. +- `sorting`: An object of type `DataTableSortingState` that holds the sorting state. + +You've also added two memoized variables: + +- `offset`: How many items to skip when fetching data based on the current page. +- `statusFilters`: The selected status filters, if any. + +Next, you'll fetch the products from the Medusa application. Assuming you have the JS SDK configured as explained in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md), add the following imports at the top of the file: + +```tsx title="src/admin/routes/custom/page.tsx" +import { sdk } from "../../lib/config" +import { useQuery } from "@tanstack/react-query" +``` + +This imports the JS SDK instance and `useQuery` from [Tanstack Query](https://tanstack.com/query/latest). + +Then, replace the `TODO` in the component with the following: + +```tsx title="src/admin/routes/custom/page.tsx" +const { data, isLoading } = useQuery({ + queryFn: () => sdk.admin.product.list({ + limit, + offset, + q: search, + status: statusFilters, + order: sorting ? `${sorting.desc ? "-" : ""}${sorting.id}` : undefined, + }), + queryKey: [["products", limit, offset, search, statusFilters, sorting?.id, sorting?.desc]], +}) + +// TODO configure data table +``` + +You use the `useQuery` hook to fetch the products from the Medusa application. In the `queryFn`, you call the `sdk.admin.product.list` method to fetch the products. You pass the following query parameters to the method: + +- `limit`: The number of products to fetch per page. +- `offset`: The number of products to skip based on the current page. +- `q`: The search query, if set. +- `status`: The status filters, if set. +- `order`: The sorting order, if set. + +So, whenever the user changes the current page, search query, status filters, or sorting, the products are fetched based on the new parameters. + +Next, you'll configure the data table. Medusa UI provides a `useDataTable` hook that helps you configure the data table. Add the following imports at the top of the file: + +```tsx title="src/admin/routes/custom/page.tsx" +import { + // ... + useDataTable, +} from "@medusajs/ui" +import { useNavigate } from "react-router-dom" +``` + +Then, replace the `TODO` in the component with the following: + +```tsx title="src/admin/routes/custom/page.tsx" +const navigate = useNavigate() + +const table = useDataTable({ + columns, + data: data?.products || [], + getRowId: (row) => row.id, + rowCount: data?.count || 0, + isLoading, + pagination: { + state: pagination, + onPaginationChange: setPagination, + }, + search: { + state: search, + onSearchChange: setSearch, + }, + filtering: { + state: filtering, + onFilteringChange: setFiltering, + }, + filters, + sorting: { + // Pass the pagination state and updater to the table instance + state: sorting, + onSortingChange: setSorting, + }, + onRowClick: (event, row) => { + // Handle row click, for example + navigate(`/products/${row.id}`) + }, +}) + +// TODO render component +``` + +The `useDataTable` hook accepts an object with the following properties: + +- columns: (\`array\`) The columns to display in the data table. You created this using the \`createDataTableColumnHelper\` utility. +- data: (\`array\`) The products fetched from the Medusa application. +- getRowId: (\`function\`) A function that returns the unique ID of a row. +- rowCount: (\`number\`) The total number of products that can be retrieved. This is used to determine the number of pages. +- isLoading: (\`boolean\`) A boolean that indicates if the data is being fetched. +- pagination: (\`object\`) An object to configure pagination. + + - state: (\`object\`) The pagination React state variable. + + - onPaginationChange: (\`function\`) A function that updates the pagination state. +- search: (\`object\`) An object to configure searching. + + - state: (\`string\`) The search query React state variable. + + - onSearchChange: (\`function\`) A function that updates the search query state. +- filtering: (\`object\`) An object to configure filtering. + + - state: (\`object\`) The filtering React state variable. + + - onFilteringChange: (\`function\`) A function that updates the filtering state. +- filters: (\`array\`) The filters to display in the data table. You created this using the \`createDataTableFilterHelper\` utility. +- sorting: (\`object\`) An object to configure sorting. + + - state: (\`object\`) The sorting React state variable. + + - onSortingChange: (\`function\`) A function that updates the sorting state. +- onRowClick: (\`function\`) A function that allows you to perform an action when the user clicks on a row. In this example, you navigate to the product's detail page. + + - event: (\`mouseevent\`) An instance of the \[MouseClickEvent]\(https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent) object. + + - row: (\`object\`) The data of the row that was clicked. + +Finally, you'll render the data table. But first, add the following imports at the top of the page: + +```tsx title="src/admin/routes/custom/page.tsx" +import { + // ... + DataTable, +} from "@medusajs/ui" +import { SingleColumnLayout } from "../../layouts/single-column" +import { Container } from "../../components/container" +``` + +Aside from the `DataTable` component, you also import the [SingleColumnLayout](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/admin-components/layouts/single-column/index.html.md) and [Container](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/admin-components/components/container/index.html.md) components implemented in other Admin Component guides. These components ensure a style consistent to other pages in the admin dashboard. + +Then, replace the `TODO` in the component with the following: + +```tsx title="src/admin/routes/custom/page.tsx" +return ( + + + + + Products +
+ + + +
+ + + + + + +) +``` + +You render the `DataTable` component and pass the `table` instance as a prop. In the `DataTable` component, you render a toolbar showing a heading, filter menu, sorting menu, and a search input. You also show pagination after the table. + +Lastly, export the component and the UI widget's configuration at the end of the file: + +```tsx title="src/admin/routes/custom/page.tsx" +// other imports... +import { defineRouteConfig } from "@medusajs/admin-sdk" +import { ChatBubbleLeftRight } from "@medusajs/icons" + +// ... + +export const config = defineRouteConfig({ + label: "Custom", + icon: ChatBubbleLeftRight, +}) + +export default CustomPage +``` + +If you start your Medusa application and go to `localhost:9000/app/custom`, you'll see the data table showing the list of products with pagination, filtering, searching, and sorting functionalities. + +### Full Example Code + +```tsx title="src/admin/routes/custom/page.tsx" +import { defineRouteConfig } from "@medusajs/admin-sdk" +import { ChatBubbleLeftRight } from "@medusajs/icons" +import { + Badge, + createDataTableColumnHelper, + createDataTableFilterHelper, + DataTable, + DataTableFilteringState, + DataTablePaginationState, + DataTableSortingState, + Heading, + useDataTable, +} from "@medusajs/ui" +import { useQuery } from "@tanstack/react-query" +import { SingleColumnLayout } from "../../layouts/single-column" +import { sdk } from "../../lib/config" +import { useMemo, useState } from "react" +import { Container } from "../../components/container" +import { HttpTypes, ProductStatus } from "@medusajs/framework/types" + +const columnHelper = createDataTableColumnHelper() + +const columns = [ + columnHelper.accessor("title", { + header: "Title", + // Enables sorting for the column. + enableSorting: true, + // If omitted, the header will be used instead if it's a string, + // otherwise the accessor key (id) will be used. + sortLabel: "Title", + // If omitted the default value will be "A-Z" + sortAscLabel: "A-Z", + // If omitted the default value will be "Z-A" + sortDescLabel: "Z-A", + }), + columnHelper.accessor("status", { + header: "Status", + cell: ({ getValue }) => { + const status = getValue() + return ( + + {status === "published" ?
