This includes configuring logging levels or saving logs to a file. - -The Medusa application registers the `Logger` class in the Medusa container and each module's container as `logger`. - -*** - -## How to Log a Message - -Resolve the `logger` using the Medusa container to log a message in your resource. - -For example, create the file `src/jobs/log-message.ts` with the following content: - -```ts title="src/jobs/log-message.ts" highlights={highlights} -import { MedusaContainer } from "@medusajs/framework/types" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" - -export default async function myCustomJob( - container: MedusaContainer -) { - const logger = container.resolve(ContainerRegistrationKeys.LOGGER) - - logger.info("I'm using the logger!") -} - -export const config = { - name: "test-logger", - // execute every minute - schedule: "* * * * *", -} -``` - -This creates a scheduled job that resolves the `logger` from the Medusa container and uses it to log a message. - -### Test the Scheduled Job - -To test out the above scheduled job, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -After a minute, you'll see the following message as part of the logged messages: - -```text -info: I'm using the logger! -``` - -*** - -## Log Levels - -The `Logger` class has the following methods: - -- `info`: The message is logged with level `info`. -- `warn`: The message is logged with level `warn`. -- `error`: The message is logged with level `error`. -- `debug`: The message is logged with level `debug`. - -Each of these methods accepts a string parameter to log in the terminal with the associated level. - -*** - -## Logging Configurations - -### Log Level - -The available log levels, from lowest to highest levels, are: - -1. `silly` -2. `debug` -3. `verbose` -4. `http` (default, meaning only HTTP requests are logged) -5. `info` -6. `warn` -7. `error` - -You can change that by setting the `LOG_LEVEL` environment variable to the minimum level you want to be logged. - -For example: - -```bash -LOG_LEVEL=error -``` - -This logs `error` messages only. - -The environment variable must be set as a system environment variable and not in `.env`. - -### Save Logs in a File - -Aside from showing the logs in the terminal, you can save the logs in a file by setting the `LOG_FILE` environment variable to the path of the file relative to the Medusa server’s root directory. - -For example: - -```bash -LOG_FILE=all.log -``` - -Your logs are now saved in the `all.log` file at the root of your Medusa application. - -The environment variable must be set as a system environment variable and not in `.env`. - -*** - -## Show Log with Progress - -The `Logger` class has an `activity` method used to log a message of level `info`. If the Medusa application is running in a development environment, a spinner starts to show the activity's progress. - -For example: - -```ts title="src/jobs/log-message.ts" -import { MedusaContainer } from "@medusajs/framework/types" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" - -export default async function myCustomJob( - container: MedusaContainer -) { - const logger = container.resolve(ContainerRegistrationKeys.LOGGER) - - const activityId = logger.activity("First log message") - - logger.progress(activityId, `Second log message`) - - logger.success(activityId, "Last log message") -} -``` - -The `activity` method returns the ID of the started activity. This ID can then be passed to one of the following methods of the `Logger` class: - -- `progress`: Log a message of level `info` that indicates progress within that same activity. -- `success`: Log a message of level `info` that indicates that the activity has succeeded. This also ends the associated activity. -- `failure`: Log a message of level `error` that indicates that the activity has failed.

Install Production Modules and Providers -Medusa's Testing Framework works for integration tests only. You can write unit tests using Jest. +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/infrastructure-modules/cache/redis/index.html.md) +- [Redis Event Bus Module](https://docs.medusajs.com/resources/infrastructure-modules/event/redis/index.html.md) +- [Workflow Engine Redis Module](https://docs.medusajs.com/resources/infrastructure-modules/workflow-engine/redis/index.html.md) +- [S3 File Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/file/s3/index.html.md) (or other file module providers production-ready). +- [SendGrid Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-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 [Infrastructure Modules](https://docs.medusajs.com/resources/infrastructure-modules/index.html.md) documentation for other modules and providers to use. *** -## Test Tools and Writing Tests +## 4. Create PostgreSQL and Redis Databases -The next chapters explain how to use the testing tools provided by `@medusajs/test-utils` to write tests. +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.

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 Infrastructure 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.

Medusa automatically registers these tools in the container, including custom ones that you've built, so that you can use them in your customizations. +A data model represents a table in the database. You create data models using Medusa's data modeling language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. -In other platforms, if you have a resource A (for example, a class) that depends on a resource B, you have to manually add resource B to the container or specify it beforehand as A's dependency, which is often done in a file separate from A's code. This becomes difficult to manage as you maintain larger applications with many changing dependencies. +You create a data model in a [module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). The module's service provides the methods to store and manage those data models. Then, you can resolve the module's service in other customizations, such as a [workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md), to manage the data models' records. -Medusa simplifies this process by giving you access to the container, with the tools or resources already registered, at all times in your customizations. When you reach a point in your code where you need a tool, you resolve it from the container and use it. +*** -For example, consider you're creating an API route that retrieves products based on filters using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md), a tool that fetches data across the application. In the API route's function, you can resolve Query from the container passed to the API route and use it: +## How to Create a Data Model -```ts highlights={highlights} -import { MedusaRequest, MedusaResponse } from "@medusajs/framework" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" +In a module, you can create a data model in a TypeScript or JavaScript file under the module's `models` directory. -export async function GET( +So, for example, assuming you have a Blog Module at `src/modules/blog`, you can create a `Post` data model by creating the `src/modules/blog/models/post.ts` file with the following content: + +![Updated directory overview after adding the data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732806790/Medusa%20Book/blog-dir-overview-1_jfvovj.jpg) + +```ts title="src/modules/blog/models/post.ts" +import { model } from "@medusajs/framework/utils" + +const Post = model.define("post", { + id: model.id().primaryKey(), + title: model.text(), +}) + +export default Post +``` + +You define the data model using the `define` method of the DML.

Migrations are useful when you re-use a module or you're working in a team, so that when one member of a team makes a database change, everyone else can reflect it on their side by running the migrations. + +For example, to generate a migration for the Blog Module, run the following command in your Medusa application's directory: + +If you're creating the module in a plugin, use the [plugin:db:generate command](https://docs.medusajs.com/resources/medusa-cli/commands/plugin#plugindbgenerate/index.html.md) instead. + +```bash +npx medusa db:generate blog +``` + +The `db:generate` command of the Medusa CLI accepts one or more module names to generate the migration for.

In the API route's function, you can resolve Query from the container passed to the API route and use it: -Learn how to create a wishlist plugin in [this guide](https://docs.medusajs.com/resources/plugins/guides/wishlist/index.html.md). +```ts highlights={highlights} +import { MedusaRequest, MedusaResponse } from "@medusajs/framework" +import { ContainerRegistrationKeys } from "@medusajs/framework/utils" -*** +export async function GET( + req: MedusaRequest, + res: MedusaResponse +) { + const query = req.scope.resolve("query") -## Plugin vs Module - -A [module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) is an isolated package related to a single domain or functionality, such as product reviews or integrating a Content Management System. A module can't access any resources in the Medusa application that are outside its codebase. - -A plugin, on the other hand, can contain multiple Medusa customizations, including modules. Your plugin can define a module, then build flows around it. - -For example, in a plugin, you can define a module that integrates a third-party service, then add a workflow that uses the module when a certain event occurs to sync data to that service. - -- You want to reuse your Medusa customizations across multiple projects. -- You want to share your Medusa customizations with the community. - -- You want to build a custom feature related to a single domain or integrate a third-party service. Instead, use a [module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). You can wrap that module in a plugin if it's used in other customizations, such as if it has a module link or it's used in a workflow. - -*** - -## How to Create a Plugin? - -The next chapter explains how you can create and publish a plugin. - - -# Data Models - -In this chapter, you'll learn what a data model is and how to create a data model. - -## What is a Data Model? - -A data model represents a table in the database. You create data models using Medusa's data modeling language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -You create a data model in a [module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). The module's service provides the methods to store and manage those data models. Then, you can resolve the module's service in other customizations, such as a [workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md), to manage the data models' records. - -*** - -## How to Create a Data Model - -In a module, you can create a data model in a TypeScript or JavaScript file under the module's `models` directory. - -So, for example, assuming you have a Blog Module at `src/modules/blog`, you can create a `Post` data model by creating the `src/modules/blog/models/post.ts` file with the following content: - -![Updated directory overview after adding the data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732806790/Medusa%20Book/blog-dir-overview-1_jfvovj.jpg) - -```ts title="src/modules/blog/models/post.ts" -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - id: model.id().primaryKey(), - title: model.text(), -}) - -export default Post -``` - -You define the data model using the `define` method of the DML. It accepts two parameters: - -1. The first one is the name of the data model's table in the database. Use snake-case names. -2. The second is an object, which is the data model's schema. The schema's properties are defined using the `model`'s methods, such as `text` and `id`. - - Data models automatically have the date properties `created_at`, `updated_at`, and `deleted_at`, so you don't need to add them manually. - -The code snippet above defines a `Post` data model with `id` and `title` properties. - -*** - -## Generate Migrations - -After you create a data model in a module, then [register that module in your Medusa configurations](https://docs.medusajs.com/learn/fundamentals/modules#4-add-module-to-medusas-configurations/index.html.md), you must generate a migration to create the data model's table in the database. - -A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations are useful when you re-use a module or you're working in a team, so that when one member of a team makes a database change, everyone else can reflect it on their side by running the migrations. - -For example, to generate a migration for the Blog Module, run the following command in your Medusa application's directory: - -If you're creating the module in a plugin, use the [plugin:db:generate command](https://docs.medusajs.com/resources/medusa-cli/commands/plugin#plugindbgenerate/index.html.md) instead. - -```bash -npx medusa db:generate blog -``` - -The `db:generate` command of the Medusa CLI accepts one or more module names to generate the migration for. It will create a migration file for the Blog Module in the directory `src/modules/blog/migrations` similar to the following: - -```ts -import { Migration } from "@mikro-orm/migrations" - -export class Migration20241121103722 extends Migration { - - async up(): Promise { - this.addSql("create table if not exists \"post\" (\"id\" text not null, \"title\" text not null, \"created_at\" timestamptz not null default now(), \"updated_at\" timestamptz not null default now(), \"deleted_at\" timestamptz null, constraint \"post_pkey\" primary key (\"id\"));") - } - - async down(): Promise { - this.addSql("drop table if exists \"post\" cascade;") - } + const { data: products } = await query.graph({ + entity: "product", + fields: ["*"], + filters: { + id: "prod_123", + }, + }) + res.json({ + products, + }) } ``` -In the migration class, the `up` method creates the table `post` and defines its columns using PostgreSQL syntax. The `down` method drops the table. +The API route accepts as a first parameter a request object that has a `scope` property, which is the Medusa container. It has a `resolve` method that resolves a resource from the container by the key it's registered with. -### Run Migrations - -To reflect the changes in the generated migration file on the database, run the `db:migrate` command: - -If you're creating the module in a plugin, run this command on the Medusa application that the plugin is installed in. - -```bash -npx medusa db:migrate -``` - -This creates the `post` table in the database. - -### Migrations on Data Model Changes - -Whenever you make a change to a data model, you must generate and run the migrations. - -For example, if you add a new column to the `Post` data model, you must generate a new migration and run it. +You can learn more about how Query works in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). *** -## Manage Data Models +## List of Resources Registered in the Medusa Container -Your module's service should extend the [service factory](https://docs.medusajs.com/learn/fundamentals/modules/service-factory/index.html.md), which generates data-management methods for your module's data models. +Find a full list of the registered resources and their registration key in [this reference](https://docs.medusajs.com/resources/medusa-container-resources/index.html.md) -For example, the Blog Module's service would have methods like `retrievePost` and `createPosts`. +*** -Refer to the [Service Factory](https://docs.medusajs.com/learn/fundamentals/modules/service-factory/index.html.md) chapter to learn more about how to extend the service factory and manage data models, and refer to the [Service Factory Reference](https://docs.medusajs.com/resources/service-factory-reference/index.html.md) for the full list of generated methods and how to use them. +## How to Resolve From the Medusa Container + +This section gives quick examples of how to resolve resources from the Medusa container in customizations other than an API route, which is covered in the section above. + +### Subscriber + +A [subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) function, which is executed when an event is emitted, accepts as a parameter an object with a `container` property, whose value is the Medusa container.

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

Add predeploy Script +## Log Levels -Before you start the Medusa application in production, you should always run migrations and sync links. +The `Logger` class has the following methods: -So, add the following script in `package.json`: +- `info`: The message is logged with level `info`. +- `warn`: The message is logged with level `warn`. +- `error`: The message is logged with level `error`. +- `debug`: The message is logged with level `debug`. -```json +Each of these methods accepts a string parameter to log in the terminal with the associated level. + +*** + +## Logging Configurations + +### Log Level + +The available log levels, from lowest to highest levels, are: + +1. `silly` +2. `debug` +3. `verbose` +4. `http` (default, meaning only HTTP requests are logged) +5. `info` +6. `warn` +7. `error` + +You can change that by setting the `LOG_LEVEL` environment variable to the minimum level you want to be logged. + +For example: + +```bash +LOG_LEVEL=error +``` + +This logs `error` messages only. + +The environment variable must be set as a system environment variable and not in `.env`. + +### Save Logs in a File + +Aside from showing the logs in the terminal, you can save the logs in a file by setting the `LOG_FILE` environment variable to the path of the file relative to the Medusa server’s root directory. + +For example: + +```bash +LOG_FILE=all.log +``` + +Your logs are now saved in the `all.log` file at the root of your Medusa application. + +The environment variable must be set as a system environment variable and not in `.env`. + +*** + +## Show Log with Progress + +The `Logger` class has an `activity` method used to log a message of level `info`. If the Medusa application is running in a development environment, a spinner starts to show the activity's progress. + +For example: + +```ts title="src/jobs/log-message.ts" +import { MedusaContainer } from "@medusajs/framework/types" +import { ContainerRegistrationKeys } from "@medusajs/framework/utils" + +export default async function myCustomJob( + container: MedusaContainer +) { + const logger = container.resolve(ContainerRegistrationKeys.LOGGER) + + const activityId = logger.activity("First log message") + + logger.progress(activityId, `Second log message`) + + logger.success(activityId, "Last log message") +} +``` + +The `activity` method returns the ID of the started activity. This ID can then be passed to one of the following methods of the `Logger` class: + +- `progress`: Log a message of level `info` that indicates progress within that same activity. +- `success`: Log a message of level `info` that indicates that the activity has succeeded. This also ends the associated activity. +- `failure`: Log a message of level `error` that indicates that the activity has failed. This also ends the associated activity. + +If you configured the `LOG_LEVEL` environment variable to a level higher than those associated with the above methods, their messages won’t be logged. + + +# Medusa Testing Tools + +In this chapter, you'll learn about Medusa's testing tools and how to install and configure them. + +## @medusajs/test-utils Package + +Medusa provides a Testing Framework to create integration tests for your custom API routes, modules, or other Medusa customizations. + +To use the Testing Framework, install `@medusajs/test-utils` as a `devDependency`: + +```bash npm2yarn +npm install --save-dev @medusajs/test-utils@latest +``` + +*** + +## Install and Configure Jest + +Writing tests with `@medusajs/test-utils`'s tools requires installing and configuring Jest in your project. + +Run the following command to install the required Jest dependencies: + +```bash npm2yarn +npm install --save-dev jest @types/jest @swc/jest +``` + +Then, create the file `jest.config.js` with the following content: + +```js title="jest.config.js" +const { loadEnv } = require("@medusajs/framework/utils") +loadEnv("test", process.cwd()) + +module.exports = { + transform: { + "^.+\\.[jt]s$": [ + "@swc/jest", + { + jsc: { + parser: { syntax: "typescript", decorators: true }, + }, + }, + ], + }, + testEnvironment: "node", + moduleFileExtensions: ["js", "ts", "json"], + modulePathIgnorePatterns: ["dist/"], + setupFiles: ["./integration-tests/setup.js"], +} + +if (process.env.TEST_TYPE === "integration:http") { + module.exports.testMatch = ["**/integration-tests/http/*.spec.[jt]s"] +} else if (process.env.TEST_TYPE === "integration:modules") { + module.exports.testMatch = ["**/src/modules/*/__tests__/**/*.[jt]s"] +} else if (process.env.TEST_TYPE === "unit") { + module.exports.testMatch = ["**/src/**/__tests__/**/*.unit.spec.[jt]s"] +} +``` + +Next, create the `integration-tests/setup.js` file with the following content: + +```js title="integration-tests/setup.js" +const { MetadataStorage } = require("@mikro-orm/core") + +MetadataStorage.clear() +``` + +*** + +## Add Test Commands + +Finally, add the following scripts to `package.json`: + +```json title="package.json" "scripts": { // ... - "predeploy": "medusa db:migrate" + "test:integration:http": "TEST_TYPE=integration:http NODE_OPTIONS=--experimental-vm-modules jest --silent=false --runInBand --forceExit", + "test:integration:modules": "TEST_TYPE=integration:modules NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit", + "test:unit": "TEST_TYPE=unit NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit" }, ``` -*** +You now have two commands: -## 3.

This section provides the general steps to perform during the deployment. +We are capable of getting a general understanding of how developers use Medusa and what general issues they run into through different means such as our Discord server, GitHub issues and discussions, and occasional one-on-one sessions. -### Set Environment Variables +However, although these methods can be insightful, they’re not enough to get a full and global understanding of how developers are using Medusa, especially in production. -When setting the environment variables of the Medusa application, set the following variables: +Collecting this data allows us to understand certain details such as: + +- What operating system do most Medusa developers use? +- What version of Medusa is widely used? +- What parts of the Medusa Admin are generally undiscovered by our users? +- How much data do users manage through our Medusa Admin? Is it being used for large number of products, orders, and other types of data? +- What Node version is globally used? Should we focus our efforts on providing support for versions that we don’t currently support? + +*** + +## Medusa Application Analytics + +This section covers which data in the Medusa application are collected and how to opt out of it. + +### Collected Data in the Medusa Application + +The following data is being collected on your Medusa application: + +- Unique project ID generated with UUID. +- Unique machine ID generated with UUID. +- Operating system information including Node version or operating system platform used. +- The version of the Medusa application and Medusa CLI are used. + +Data is only collected when the Medusa application is run with the command `medusa start`. + +### How to Opt Out + +If you prefer to disable data collection, you can do it either by setting the following environment variable to true: ```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 +MEDUSA_DISABLE_TELEMETRY=true ``` -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.

You add the brand's ID to the data payload, informing the subscribers which brand was created. - -You'll learn how to handle this event in a later step. - -*** - -## 2. Create Sync to Third-Party System Workflow - -The subscriber that will listen to the `brand.created` event will sync the created brand to the third-party CMS. So, you'll implement the syncing logic in a workflow, then execute the workflow in the subscriber. - -Workflows have a built-in durable execution engine that helps you complete tasks spanning multiple systems. Also, their rollback mechanism ensures that data is consistent across systems even when errors occur during execution. - -Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). - -You'll create a `syncBrandToSystemWorkflow` that has two steps: - -- `useQueryGraphStep`: a step that Medusa provides to retrieve data using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). You'll use this to retrieve the brand's details using its ID. -- `syncBrandToCmsStep`: a step that you'll create to sync the brand to the CMS. - -### syncBrandToCmsStep - -To implement the step that syncs the brand to the CMS, create the file `src/workflows/sync-brands-to-cms.ts` with the following content: - -![Directory structure of the Medusa application after adding the file](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493547/Medusa%20Book/cms-dir-overview-4_u5t0ug.jpg) - -```ts title="src/workflows/sync-brands-to-cms.ts" highlights={syncStepHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { InferTypeOf } from "@medusajs/framework/types" -import { Brand } from "../modules/brand/models/brand" -import { CMS_MODULE } from "../modules/cms" -import CmsModuleService from "../modules/cms/service" - -type SyncBrandToCmsStepInput = { - brand: InferTypeOf -} - -const syncBrandToCmsStep = createStep( - "sync-brand-to-cms", - async ({ brand }: SyncBrandToCmsStepInput, { container }) => { - const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) - - await cmsModuleService.createBrand(brand) - - return new StepResponse(null, brand.id) - }, - async (id, { container }) => { - if (!id) { - return - } - - const cmsModuleService: CmsModuleService = container.resolve(CMS_MODULE) - - await cmsModuleService.deleteBrand(id) - } -) -``` - -You create the `syncBrandToCmsStep` that accepts a brand as an input. In the step, you resolve the CMS Module's service from the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) and use its `createBrand` method. This method will create the brand in the third-party CMS. - -You also pass the brand's ID to the step's compensation function. In this function, you delete the brand in the third-party CMS if an error occurs during the workflow's execution. - -Learn more about compensation functions in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). - -### Create Workflow - -You can now create the workflow that uses the above step. Add the workflow to the same `src/workflows/sync-brands-to-cms.ts` file: - -```ts title="src/workflows/sync-brands-to-cms.ts" highlights={syncWorkflowHighlights} -// other imports... -import { - // ... - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" - -// ... - -type SyncBrandToCmsWorkflowInput = { - id: string -} - -export const syncBrandToCmsWorkflow = createWorkflow( - "sync-brand-to-cms", - (input: SyncBrandToCmsWorkflowInput) => { - // @ts-ignore - const { data: brands } = useQueryGraphStep({ - entity: "brand", - fields: ["*"], - filters: { - id: input.id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - syncBrandToCmsStep({ - brand: brands[0], - } as SyncBrandToCmsStepInput) - - return new WorkflowResponse({}) - } -) -``` - -You create a `syncBrandToCmsWorkflow` that accepts the brand's ID as input. The workflow has the following steps: - -- `useQueryGraphStep`: Retrieve the brand's details using Query. You pass the brand's ID as a filter, and set the `throwIfKeyNotFound` option to true so that the step throws an error if a brand with the specified ID doesn't exist. -- `syncBrandToCmsStep`: Create the brand in the third-party CMS. - -You'll execute this workflow in the subscriber next. - -Learn more about `useQueryGraphStep` in [this reference](https://docs.medusajs.com/resources/references/helper-steps/useQueryGraphStep/index.html.md). - -*** - -## 3. Handle brand.created Event - -You now have a workflow with the logic to sync a brand to the CMS. You need to execute this workflow whenever the `brand.created` event is emitted. So, you'll create a subscriber that listens to and handle the event. - -Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, create the file `src/subscribers/brand-created.ts` with the following content: - -![Directory structure of the Medusa application after adding the subscriber](https://res.cloudinary.com/dza7lstvk/image/upload/v1733493774/Medusa%20Book/cms-dir-overview-5_iqqwvg.jpg) - -```ts title="src/subscribers/brand-created.ts" highlights={subscriberHighlights} -import type { - SubscriberConfig, - SubscriberArgs, -} from "@medusajs/framework" -import { syncBrandToCmsWorkflow } from "../workflows/sync-brands-to-cms" - -export default async function brandCreatedHandler({ - event: { data }, - container, -}: SubscriberArgs<{ id: string }>) { - await syncBrandToCmsWorkflow(container).run({ - input: data, - }) -} - -export const config: SubscriberConfig = { - event: "brand.created", -} -``` - -A subscriber file must export: - -- The asynchronous function that's executed when the event is emitted. This must be the file's default export. -- An object that holds the subscriber's configurations. It has an `event` property that indicates the name of the event that the subscriber is listening to. - -The subscriber function accepts an object parameter that has two properties: - -- `event`: An object of event details. Its `data` property holds the event's data payload, which is the brand's ID. -- `container`: The Medusa container used to resolve Framework and commerce tools. - -In the function, you execute the `syncBrandToCmsWorkflow`, passing it the data payload as an input. So, everytime a brand is created, Medusa will execute this function, which in turn executes the workflow to sync the brand to the CMS. - -Learn more about subscribers in [this chapter](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md). - -*** - -## Test it Out - -To test the subscriber and workflow out, you'll use the [Create Brand API route](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md) you created in a previous chapter. - -First, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Since the `/admin/brands` API route has a `/admin` prefix, it's only accessible by authenticated admin users. So, to retrieve an authenticated token of your admin user, send a `POST` request to the `/auth/user/emailpass` API Route: - -```bash -curl -X POST 'http://localhost:9000/auth/user/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "admin@medusa-test.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password with your admin user's credentials. - -Don't have an admin user? Refer to [this guide](https://docs.medusajs.com/learn/installation#create-medusa-admin-user/index.html.md). - -Then, send a `POST` request to `/admin/brands`, passing the token received from the previous request in the `Authorization` header: - -```bash -curl -X POST 'http://localhost:9000/admin/brands' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "name": "Acme" -}' -``` - -This request returns the created brand. If you check the logs, you'll find the `brand.created` event was emitted, and that the request to the third-party system was simulated: - -```plain -info: Processing brand.created which has 1 subscribers -http: POST /admin/brands ← - (200) - 16.418 ms -info: Sending a POST request to /brands. -info: Request Data: { - "id": "01JEDWENYD361P664WRQPMC3J8", - "name": "Acme", - "created_at": "2024-12-06T11:42:32.909Z", - "updated_at": "2024-12-06T11:42:32.909Z", - "deleted_at": null -} -info: API Key: "123" -``` - -*** - -## Next Chapter: Sync Brand from Third-Party CMS to Medusa - -You can also automate syncing data from a third-party system to Medusa at a regular interval.

You create these widgets as React components that allow admin users to perform custom actions. +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. -For example, you can add a widget on the product details page that allow admin users to sync products to a third-party service. +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.

So, you add a check constraint that fails when inserting a record with a negative price value. *** -## Admin Components List +## How to Set a Check Constraint? -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. +To set check constraints on a data model, use the `checks` method. This method accepts an array of check constraints to apply on the data model. + +For example, to set a check constraint on a `price` property that ensures its value can only be a positive number: + +```ts highlights={checks1Highlights} +import { model } from "@medusajs/framework/utils" + +const CustomProduct = model.define("custom_product", { + // ... + price: model.bigNumber(), +}) +.checks([ + (columns) => `${columns.price} >= 0`, +]) +``` + +The item passed in the array parameter of `checks` can be a callback function that accepts as a parameter an object whose keys are the names of the properties in the data model schema, and values the respective column name in the database. + +The function returns a string indicating the [SQL check constraint expression](https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-CHECK-CONSTRAINTS). In the expression, use the `columns` parameter to access a property's column name. + +You can also pass an object to the `checks` method: + +```ts highlights={checks2Highlights} +import { model } from "@medusajs/framework/utils" + +const CustomProduct = model.define("custom_product", { + // ... + price: model.bigNumber(), +}) +.checks([ + { + name: "custom_product_price_check", + expression: (columns) => `${columns.price} >= 0`, + }, +]) +``` + +The object accepts the following properties: + +- `name`: The check constraint's name. +- `expression`: A function similar to the one that can be passed to the array. It accepts an object of columns and returns an [SQL check constraint expression](https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-CHECK-CONSTRAINTS). + +*** + +## Apply in Migrations + +After adding the check constraint, make sure to generate and run migrations if you already have the table in the database. Otherwise, the check constraint won't be reflected. + +To generate a migration for the data model's module then reflect it on the database, run the following command: + +```bash +npx medusa db:generate custom_module +npx medusa db:migrate +``` + +The first command generates the migration under the `migrations` directory of your module's directory, and the second reflects it on the database. + + +# Manage Relationships + +In this chapter, you'll learn how to manage relationships between data models when creating, updating, or retrieving records using the module's main service. + +This chapter applies to data model relationships within the same module. To manage linked data models across modules, check out [Links](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) and [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). + +## Manage One-to-One Relationship + +### BelongsTo Side of One-to-One + +When you create a record of a data model that belongs to another through a one-to-one relation, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. + +For example, assuming you have the [User and Email data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-one-relationship/index.html.md), set an email's user ID as follows: + +```ts highlights={belongsHighlights} +// when creating an email +const email = await helloModuleService.createEmails({ + // other properties... + user_id: "123", +}) + +// when updating an email +const email = await helloModuleService.updateEmails({ + id: "321", + // other properties... + user_id: "123", +}) +``` + +In the example above, you pass the `user_id` property when creating or updating an email to specify the user it belongs to. + +### HasOne Side + +When you create a record of a data model that has one of another, pass the ID of the other data model's record in the relation property. + +For example, assuming you have the [User and Email data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-one-relationship/index.html.md), set a user's email ID as follows: + +```ts highlights={hasOneHighlights} +// when creating a user +const user = await helloModuleService.createUsers({ + // other properties... + email: "123", +}) + +// when updating a user +const user = await helloModuleService.updateUsers({ + id: "321", + // other properties... + email: "123", +}) +``` + +In the example above, you pass the `email` property when creating or updating a user to specify the email it has. + +*** + +## Manage One-to-Many Relationship + +In a one-to-many relationship, you can only manage the associations from the `belongsTo` side. + +When you create a record of the data model on the `belongsTo` side, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. + +For example, assuming you have the [Product and Store data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-many-relationship/index.html.md), set a product's store ID as follows: + +```ts highlights={manyBelongsHighlights} +// when creating a product +const product = await helloModuleService.createProducts({ + // other properties... + store_id: "123", +}) + +// when updating a product +const product = await helloModuleService.updateProducts({ + id: "321", + // other properties... + store_id: "123", +}) +``` + +In the example above, you pass the `store_id` property when creating or updating a product to specify the store it belongs to. + +*** + +## Manage Many-to-Many Relationship + +If your many-to-many relation is represented with a [pivotEntity](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), refer to [this section](#manage-many-to-many-relationship-with-pivotentity) instead. + +### Create Associations + +When you create a record of a data model that has a many-to-many relationship to another data model, pass an array of IDs of the other data model's records in the relation property. + +For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), set the association between products and orders as follows: + +```ts highlights={manyHighlights} +// when creating a product +const product = await helloModuleService.createProducts({ + // other properties... + orders: ["123", "321"], +}) + +// when creating an order +const order = await helloModuleService.createOrders({ + id: "321", + // other properties... + products: ["123", "321"], +}) +``` + +In the example above, you pass the `orders` property when you create a product, and you pass the `products` property when you create an order. + +### Update Associations + +When you use the `update` methods generated by the service factory, you also pass an array of IDs as the relation property's value to add new associated records. + +However, this removes any existing associations to records whose IDs aren't included in the array. + +For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), you update the product's related orders as so: + +```ts +const product = await helloModuleService.updateProducts({ + id: "123", + // other properties... + orders: ["321"], +}) +``` + +If the product was associated with an order, and you don't include that order's ID in the `orders` array, the association between the product and order is removed. + +So, to add a new association without removing existing ones, retrieve the product first to pass its associated orders when updating the product: + +```ts highlights={updateAssociationHighlights} +const product = await helloModuleService.retrieveProduct( + "123", + { + relations: ["orders"], + } +) + +const updatedProduct = await helloModuleService.updateProducts({ + id: product.id, + // other properties... + orders: [ + ...product.orders.map((order) => order.id), + "321", + ], +}) +``` + +This keeps existing associations between the product and orders, and adds a new one. + +*** + +## Manage Many-to-Many Relationship with pivotEntity + +If your many-to-many relation is represented without a [pivotEntity](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), refer to [this section](#manage-many-to-many-relationship) instead. + +If you have a many-to-many relation with a `pivotEntity` specified, make sure to pass the data model representing the pivot table to [MedusaService](https://docs.medusajs.com/learn/fundamentals/modules/service-factory/index.html.md) that your module's service extends. + +For example, assuming you have the [Order, Product, and OrderProduct models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), add `OrderProduct` to `MedusaService`'s object parameter: + +```ts highlights={["4"]} +class BlogModuleService extends MedusaService({ + Order, + Product, + OrderProduct, +}) {} +``` + +This will generate Create, Read, Update and Delete (CRUD) methods for the `OrderProduct` data model, which you can use to create relations between orders and products and manage the extra columns in the pivot table. + +For example: + +```ts +// create order-product association +const orderProduct = await blogModuleService.createOrderProducts({ + order_id: "123", + product_id: "123", + metadata: { + test: true, + }, +}) + +// update order-product association +const orderProduct = await blogModuleService.updateOrderProducts({ + id: "123", + metadata: { + test: false, + }, +}) + +// delete order-product association +await blogModuleService.deleteOrderProducts("123") +``` + +Since the `OrderProduct` data model belongs to the `Order` and `Product` data models, you can set its order and product as explained in the [one-to-many relationship section](#manage-one-to-many-relationship) using `order_id` and `product_id`. + +Refer to the [service factory reference](https://docs.medusajs.com/resources/service-factory-reference/index.html.md) for a full list of generated methods and their usages. + +*** + +## Retrieve Records of Relation + +The `list`, `listAndCount`, and `retrieve` methods of a module's main service accept as a second parameter an object of options. + +To retrieve the records associated with a data model's records through a relationship, pass in the second parameter object a `relations` property whose value is an array of relationship names. + +For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), you retrieve a product's orders as follows: + +```ts highlights={retrieveHighlights} +const product = await blogModuleService.retrieveProducts( + "123", + { + relations: ["orders"], + } +) +``` + +In the example above, the retrieved product has an `orders` property, whose value is an array of orders associated with the product. + + +# Infer Type of Data Model + +In this chapter, you'll learn how to infer the type of a data model. + +## How to Infer Type of Data Model? + +Consider you have a `Post` data model. You can't reference this data model in a type, such as a workflow input or service method output types, since it's a variable. + +Instead, Medusa provides `InferTypeOf` that transforms your data model to a type. + +For example: + +```ts +import { InferTypeOf } from "@medusajs/framework/types" +import { Post } from "../modules/blog/models/post" // relative path to the model + +export type Post = InferTypeOf +``` + +`InferTypeOf` accepts as a type argument the type of the data model. + +Since the `Post` data model is a variable, use the `typeof` operator to pass the data model as a type argument to `InferTypeOf`. + +You can now use the `Post` type to reference a data model in other types, such as in workflow inputs or service method outputs: + +```ts title="Example Service" +// other imports... +import { InferTypeOf } from "@medusajs/framework/types" +import { Post } from "../models/post" + +type Post = InferTypeOf + +class BlogModuleService extends MedusaService({ Post }) { + async doSomething(): Promise { + // ... + } +} +``` + + +# Data Model Properties + +In this chapter, you'll learn about the different property types you can use in a data model and how to configure a data model's properties. + +## Data Model's Default Properties + +By default, Medusa creates the following properties for every data model: + +- `created_at`: A [dateTime](#dateTime) property that stores when a record of the data model was created. +- `updated_at`: A [dateTime](#dateTime) property that stores when a record of the data model was updated. +- `deleted_at`: A [dateTime](#dateTime) property that stores when a record of the data model was deleted. When you soft-delete a record, Medusa sets the `deleted_at` property to the current date. + +*** + +## Property Types + +This section covers the different property types you can define in a data model's schema using the `model` methods. + +### id + +The `id` method defines an automatically generated string ID property.

Migrations are useful when you re-use a module or you're working in a team, so that when one member of a team makes a database change, everyone else can reflect it on their side by running the migrations. + +The migration's file has a class with two methods: + +- The `up` method reflects changes on the database. +- The `down` method reverts the changes made in the `up` method. + +*** + +## Generate Migration + +Instead of you writing the migration manually, the Medusa CLI tool provides a [db:generate](https://docs.medusajs.com/resources/medusa-cli/commands/db#dbgenerate/index.html.md) command to generate a migration for a modules' data models. + +For example, assuming you have a `blog` Module, you can generate a migration for it by running the following command: + +```bash +npx medusa db:generate blog +``` + +This generates a migration file under the `migrations` directory of the Blog Module. You can then run it to reflect the changes in the database as mentioned in [this section](#run-the-migration). + +*** + +## Write a Migration Manually + +You can also write migrations manually. To do that, create a file in the `migrations` directory of the module and in it, a class that has an `up` and `down` method. The class's name should be of the format `Migration{YEAR}{MONTH}{DAY}{HOUR}{MINUTE}.ts` to ensure migrations are ran in the correct order. + +For example: + +```ts title="src/modules/blog/migrations/Migration202507021059.ts" +import { Migration } from "@mikro-orm/migrations" + +export class Migration202507021059 extends Migration { + + async up(): Promise { + this.addSql("create table if not exists \"author\" (\"id\" text not null, \"name\" text not null, \"created_at\" timestamptz not null default now(), \"updated_at\" timestamptz not null default now(), \"deleted_at\" timestamptz null, constraint \"author_pkey\" primary key (\"id\"));") + } + + async down(): Promise { + this.addSql("drop table if exists \"author\" cascade;") + } + +} +``` + +The migration class in the file extends the `Migration` class imported from `@mikro-orm/migrations`. In the `up` and `down` method of the migration class, you use the `addSql` method provided by MikroORM's `Migration` class to run PostgreSQL syntax. + +In the example above, the `up` method creates the table `author`, and the `down` method drops the table if the migration is reverted. + +Refer to [MikroORM's documentation](https://mikro-orm.io/docs/migrations#migration-class) for more details on writing migrations. + +*** + +## Run the Migration + +To run your migration, run the following command: + +This command also syncs module links. If you don't want that, use the `--skip-links` option. + +```bash +npx medusa db:migrate +``` + +This reflects the changes in the database as implemented in the migration's `up` method. + +*** + +## Rollback the Migration + +To rollback or revert the last migration you ran for a module, run the following command: + +```bash +npx medusa db:rollback blog +``` + +This rolls back the last ran migration on the Blog Module. + +### Caution: Rollback Migration before Deleting + +If you need to delete a migration file, make sure to rollback the migration first. Otherwise, you might encounter issues when generating and running new migrations. + +For example, if you delete the migration of the Blog Module, then try to create a new one, Medusa will create a brand new migration that re-creates the tables or indices. If those are still in the database, you might encounter errors. + +So, always rollback the migration before deleting it. + +*** + +## More Database Commands + +To learn more about the Medusa CLI's database commands, refer to [this CLI reference](https://docs.medusajs.com/resources/medusa-cli/commands/db/index.html.md). # Pass Additional Data to Medusa's API Route @@ -8337,113 +9552,6 @@ createProductsWorkflow.hooks.productsCreated( This updates the products to their original state before adding the brand to their `metadata` property. -# Throwing and Handling Errors - -In this guide, you'll learn how to throw errors in your Medusa application, how it affects an API route's response, and how to change the default error handler of your Medusa application. - -## Throw MedusaError - -When throwing an error in your API routes, middlewares, workflows, or any customization, throw a `MedusaError` from the Medusa Framework. - -The Medusa application's API route error handler then wraps your thrown error in a uniform object and returns it in the response. - -For example: - -```ts -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" -import { MedusaError } from "@medusajs/framework/utils" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - if (!req.query.q) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "The `q` query parameter is required." - ) - } - - // ... -} -``` - -The `MedusaError` class accepts in its constructor two parameters: - -1.

If your plugin doesn't integrate a third-party service, you can skip this step. - -```json title="package.json" -{ - "keywords": [ - "medusa-plugin-integration", - "medusa-v2" - ], - // ... -} -``` - -In addition, make sure to use one of the following keywords based on your integration type: - -|Keyword|Description|Example| -|---|---|---| -|\`medusa-plugin-analytics\`|Analytics service integration|Google Analytics| -|\`medusa-plugin-auth\`|Authentication service integration|Auth0| -|\`medusa-plugin-cms\`|CMS service integration|Contentful| -|\`medusa-plugin-notification\`|Notification service integration|Twilio SMS| -|\`medusa-plugin-payment\`|Payment service integration|PayPal| -|\`medusa-plugin-search\`|Search service integration|MeiliSearch| -|\`medusa-plugin-shipping\`|Shipping service integration|DHL| -|\`medusa-plugin-other\`|Other third-party integrations|Sentry| - -### Package Dependencies - -Your plugin project will already have the dependencies mentioned in this section. Unless you made changes to the dependencies, you can skip this section. - -In the `package.json` file you must have the Medusa dependencies as `devDependencies` and `peerDependencies`. In addition, you must have `@swc/core` as a `devDependency`, as it's used by the plugin CLI tools. - -For example, assuming `2.5.0` is the latest Medusa version: - -```json title="package.json" -{ - "devDependencies": { - "@medusajs/admin-sdk": "2.5.0", - "@medusajs/cli": "2.5.0", - "@medusajs/framework": "2.5.0", - "@medusajs/medusa": "2.5.0", - "@medusajs/test-utils": "2.5.0", - "@medusajs/ui": "4.0.4", - "@medusajs/icons": "2.5.0", - "@swc/core": "1.5.7", - }, - "peerDependencies": { - "@medusajs/admin-sdk": "2.5.0", - "@medusajs/cli": "2.5.0", - "@medusajs/framework": "2.5.0", - "@medusajs/test-utils": "2.5.0", - "@medusajs/medusa": "2.5.0", - "@medusajs/ui": "4.0.3", - "@medusajs/icons": "2.5.0", - } -} -``` - -### Package Exports - -Your plugin project will already have the exports mentioned in this section. Unless you made changes to the exports or you created your plugin before [Medusa v2.7.0](https://github.com/medusajs/medusa/releases/tag/v2.7.0), you can skip this section. - -In the `package.json` file, make sure your plugin has the following exports: - -```json title="package.json" -{ - "exports": { - "./package.json": "./package.json", - "./workflows": "./.medusa/server/src/workflows/index.js", - "./.medusa/server/src/modules/*": "./.medusa/server/src/modules/*/index.js", - "./providers/*": "./.medusa/server/src/providers/*/index.js", - "./admin": { - "import": "./.medusa/server/src/admin/index.mjs", - "require": "./.medusa/server/src/admin/index.js", - "default": "./.medusa/server/src/admin/index.js" - }, - "./*": "./.medusa/server/src/*.js" - } -} -``` - -Aside from the `./package.json`, `./providers`, and `./admin`, these exports are only a recommendation. You can cherry-pick the files and directories you want to export. - -The plugin exports the following files and directories: - -- `./package.json`: The `package.json` file. Medusa needs to access the `package.json` when registering the plugin. -- `./workflows`: The workflows exported in `./src/workflows/index.ts`. -- `./.medusa/server/src/modules/*`: The definition file of modules. This is useful if you create links to the plugin's modules in the Medusa application. -- `./providers/*`: The definition file of module providers. This is useful if your plugin includes a module provider, allowing you to register the plugin's providers in Medusa applications. Learn more in the [Create Module Providers](#create-module-providers) section. -- `./admin`: The admin extensions exported in `./src/admin/index.ts`. -- `./*`: Any other files in the plugin's `src` directory. - -*** - -## 3. Publish Plugin Locally for Development and Testing - -Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. - -### Publish and Install Local Package - -### Prerequisites - -- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) - -The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. - -To publish the plugin to the local registry, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:publish -``` - -This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. - -Next, navigate to your Medusa application: - -```bash title="Medusa application" -cd ~/path/to/medusa-app -``` - -Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. - -Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm install --save-dev yalc -``` - -After that, run the following Medusa CLI command to install the plugin: - -```bash title="Medusa application" -npx medusa plugin:add @myorg/plugin-name -``` - -Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. - -### Register Plugin in Medusa Application - -After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. - -Add the plugin to the `plugins` array in the `medusa-config.ts` file: - -```ts title="medusa-config.ts" highlights={pluginHighlights} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: {}, - }, - ], -}) -``` - -The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. - -#### Pass Module Options through Plugin - -Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. - -For example: - -```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: { - apiKey: true, - }, - }, - ], -}) -``` - -The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). - -### Watch Plugin Changes During Development - -While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. - -To do that, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:develop -``` - -This command will: - -- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. -- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. - -### Start Medusa Application - -You can start your Medusa application's development server to test out your plugin: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm run dev -``` - -While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. - -*** - -## 4. Create Customizations in the Plugin - -You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. - -- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) -- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) -- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) -- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) -- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) -- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) -- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) -- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) -- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) - -While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). - -### Generating Migrations for Modules - -During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: - -```plain title="Plugin project" -DB_USERNAME=postgres -DB_PASSWORD=123... -DB_HOST=localhost -DB_PORT=5432 -DB_NAME=db_name -``` - -You can add these environment variables in a `.env` file in your plugin project. The variables are: - -- `DB_USERNAME`: The username of the PostgreSQL user to connect to the database. -- `DB_PASSWORD`: The password of the PostgreSQL user to connect to the database. -- `DB_HOST`: The host of the PostgreSQL database. Typically, it's `localhost` if you're running the database locally. -- `DB_PORT`: The port of the PostgreSQL database. Typically, it's `5432` if you're running the database locally. -- `DB_NAME`: The name of the PostgreSQL database to connect to. - -Then, run the following command in your plugin project to generate migrations for the modules in your plugin: - -```bash title="Plugin project" -npx medusa plugin:db:generate -``` - -This command generates migrations for all modules in the plugin. - -Finally, run these migrations on the Medusa application that the plugin is installed in using the `db:migrate` command: - -```bash title="Medusa application" -npx medusa db:migrate -``` - -The migrations in your application, including your plugin, will run and update the database. - -### Importing Module Resources - -In the [Prepare Plugin](#2-prepare-plugin) section, you learned about [exported resources](#package-exports) in your plugin. - -These exports allow you to import your plugin resources in your Medusa application, including workflows, links and modules. - -For example, to import the plugin's workflow in your Medusa application: - -`@myorg/plugin-name` is the plugin package's name. - -```ts -import { Workflow1, Workflow2 } from "@myorg/plugin-name/workflows" -import BlogModule from "@myorg/plugin-name/modules/blog" -// import other files created in plugin like ./src/types/blog.ts -import BlogType from "@myorg/plugin-name/types/blog" -``` - -### Create Module Providers - -The [exported resources](#package-exports) also allow you to import module providers in your plugin and register them in the Medusa application's configuration. A module provider is a module that provides the underlying logic or integration related to a commerce or Infrastructure Module. - -For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/index.html.md) called `my-notification`, you can register it in your Medusa application's configuration like this: - -`@myorg/plugin-name` is the plugin package's name. - -```ts highlights={[["9"]]} title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - { - resolve: "@myorg/plugin-name/providers/my-notification", - id: "my-notification", - options: { - channels: ["email"], - // provider options... - }, - }, - ], - }, - }, - ], -}) -``` - -You pass to `resolve` the path to the provider relative to the plugin package. So, in this example, the `my-notification` provider is located in `./src/providers/my-notification/index.ts` of the plugin. - -To learn how to create module providers, refer to the following guides: - -- [File Module Provider](https://docs.medusajs.com/resources/references/file-provider-module/index.html.md) -- [Notification Module Provider](https://docs.medusajs.com/resources/references/notification-provider-module/index.html.md) -- [Auth Module Provider](https://docs.medusajs.com/resources/references/auth/provider/index.html.md) -- [Payment Module Provider](https://docs.medusajs.com/resources/references/payment/provider/index.html.md) -- [Fulfillment Module Provider](https://docs.medusajs.com/resources/references/fulfillment/provider/index.html.md) -- [Tax Module Provider](https://docs.medusajs.com/resources/references/tax/provider/index.html.md) - -*** - -## 5. Publish Plugin to NPM - -Make sure to add the keywords mentioned in the [Package Keywords](#package-keywords) section in your plugin's `package.json` file. - -Medusa's CLI tool provides a command that bundles your plugin to be published to npm. Once you're ready to publish your plugin publicly, run the following command in your plugin project: - -```bash -npx medusa plugin:build -``` - -The command will compile an output in the `.medusa/server` directory. - -You can now publish the plugin to npm using the [NPM CLI tool](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm). Run the following command to publish the plugin to npm: - -```bash -npm publish -``` - -If you haven't logged in before with your NPM account, you'll be asked to log in first. Then, your package is published publicly to be used in any Medusa application. - -### Install Public Plugin in Medusa Application - -You install a plugin that's published publicly using your package manager. For example: - -```bash npm2yarn -npm install @myorg/plugin-name -``` - -Where `@myorg/plugin-name` is the name of your plugin as published on NPM. - -Then, register the plugin in your Medusa application's configurations as explained in [this section](#register-plugin-in-medusa-application). - -*** - -## Update a Published Plugin - -To update the Medusa dependencies in a plugin, refer to [this documentation](https://docs.medusajs.com/learn/update#update-plugin-project/index.html.md). - -If you've published a plugin and you've made changes to it, you'll have to publish the update to NPM again. - -First, run the following command to change the version of the plugin: - -```bash -npm version -``` - -Where `` indicates the type of version update you’re publishing. For example, it can be `major` or `minor`. Refer to the [npm version documentation](https://docs.npmjs.com/cli/v10/commands/npm-version) for more information. - -Then, re-run the same commands for publishing a plugin: - -```bash -npx medusa plugin:build -npm publish -``` - -This will publish an updated version of your plugin under a new version. - - -# Add Data Model Check Constraints - -In this chapter, you'll learn how to add check constraints to your data model. - -## What is a Check Constraint? - -A check constraint is a condition that must be satisfied by records inserted into a database table, otherwise an error is thrown. - -For example, if you have a data model with a `price` property, you want to only allow positive number values. So, you add a check constraint that fails when inserting a record with a negative price value. - -*** - -## How to Set a Check Constraint? - -To set check constraints on a data model, use the `checks` method. This method accepts an array of check constraints to apply on the data model. - -For example, to set a check constraint on a `price` property that ensures its value can only be a positive number: - -```ts highlights={checks1Highlights} -import { model } from "@medusajs/framework/utils" - -const CustomProduct = model.define("custom_product", { - // ... - price: model.bigNumber(), -}) -.checks([ - (columns) => `${columns.price} >= 0`, -]) -``` - -The item passed in the array parameter of `checks` can be a callback function that accepts as a parameter an object whose keys are the names of the properties in the data model schema, and values the respective column name in the database. - -The function returns a string indicating the [SQL check constraint expression](https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-CHECK-CONSTRAINTS). In the expression, use the `columns` parameter to access a property's column name. - -You can also pass an object to the `checks` method: - -```ts highlights={checks2Highlights} -import { model } from "@medusajs/framework/utils" - -const CustomProduct = model.define("custom_product", { - // ... - price: model.bigNumber(), -}) -.checks([ - { - name: "custom_product_price_check", - expression: (columns) => `${columns.price} >= 0`, - }, -]) -``` - -The object accepts the following properties: - -- `name`: The check constraint's name. -- `expression`: A function similar to the one that can be passed to the array. It accepts an object of columns and returns an [SQL check constraint expression](https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-CHECK-CONSTRAINTS). - -*** - -## Apply in Migrations - -After adding the check constraint, make sure to generate and run migrations if you already have the table in the database. Otherwise, the check constraint won't be reflected. - -To generate a migration for the data model's module then reflect it on the database, run the following command: - -```bash -npx medusa db:generate custom_module -npx medusa db:migrate -``` - -The first command generates the migration under the `migrations` directory of your module's directory, and the second reflects it on the database. - - -# Infer Type of Data Model - -In this chapter, you'll learn how to infer the type of a data model. - -## How to Infer Type of Data Model? - -Consider you have a `Post` data model. You can't reference this data model in a type, such as a workflow input or service method output types, since it's a variable. - -Instead, Medusa provides `InferTypeOf` that transforms your data model to a type. - -For example: - -```ts -import { InferTypeOf } from "@medusajs/framework/types" -import { Post } from "../modules/blog/models/post" // relative path to the model - -export type Post = InferTypeOf -``` - -`InferTypeOf` accepts as a type argument the type of the data model. - -Since the `Post` data model is a variable, use the `typeof` operator to pass the data model as a type argument to `InferTypeOf`. - -You can now use the `Post` type to reference a data model in other types, such as in workflow inputs or service method outputs: - -```ts title="Example Service" -// other imports... -import { InferTypeOf } from "@medusajs/framework/types" -import { Post } from "../models/post" - -type Post = InferTypeOf - -class BlogModuleService extends MedusaService({ Post }) { - async doSomething(): Promise { - // ... - } -} -``` - - -# Data Model Database Index - -In this chapter, you’ll learn how to define a database index on a data model. - -You can also define an index on a property as explained in the [Properties chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties#define-database-index-on-property/index.html.md). - -## Define Database Index on Data Model - -A data model has an `indexes` method that defines database indices on its properties. - -The index can be on multiple columns (composite index). For example: - -```ts highlights={dataModelIndexHighlights} -import { model } from "@medusajs/framework/utils" - -const MyCustom = model.define("my_custom", { - id: model.id().primaryKey(), - name: model.text(), - age: model.number(), -}).indexes([ - { - on: ["name", "age"], - }, -]) - -export default MyCustom -``` - -The `indexes` method receives an array of indices as a parameter. Each index is an object with a required `on` property indicating the properties to apply the index on. - -In the above example, you define a composite index on the `name` and `age` properties. - -### Index Conditions - -An index can have conditions. For example: - -```ts highlights={conditionHighlights} -import { model } from "@medusajs/framework/utils" - -const MyCustom = model.define("my_custom", { - id: model.id().primaryKey(), - name: model.text(), - age: model.number(), -}).indexes([ - { - on: ["name", "age"], - where: { - age: 30, - }, - }, -]) - -export default MyCustom -``` - -The index object passed to `indexes` accepts a `where` property whose value is an object of conditions. The object's key is a property's name, and its value is the condition on that property. - -In the example above, the composite index is created on the `name` and `age` properties when the `age`'s value is `30`. - -A property's condition can be a negation. For example: - -```ts highlights={negationHighlights} -import { model } from "@medusajs/framework/utils" - -const MyCustom = model.define("my_custom", { - id: model.id().primaryKey(), - name: model.text(), - age: model.number().nullable(), -}).indexes([ - { - on: ["name", "age"], - where: { - age: { - $ne: null, - }, - }, - }, -]) - -export default MyCustom -``` - -A property's value in `where` can be an object having a `$ne` property. `$ne`'s value indicates what the specified property's value shouldn't be. - -In the example above, the composite index is created on the `name` and `age` properties when `age`'s value is not `null`. - -### Unique Database Index - -The object passed to `indexes` accepts a `unique` property indicating that the created index must be a unique index. - -For example: - -```ts highlights={uniqueHighlights} -import { model } from "@medusajs/framework/utils" - -const MyCustom = model.define("my_custom", { - id: model.id().primaryKey(), - name: model.text(), - age: model.number(), -}).indexes([ - { - on: ["name", "age"], - unique: true, - }, -]) - -export default MyCustom -``` - -This creates a unique composite index on the `name` and `age` properties. - - -# Manage Relationships - -In this chapter, you'll learn how to manage relationships between data models when creating, updating, or retrieving records using the module's main service. - -This chapter applies to data model relationships within the same module. To manage linked data models across modules, check out [Links](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) and [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). - -## Manage One-to-One Relationship - -### BelongsTo Side of One-to-One - -When you create a record of a data model that belongs to another through a one-to-one relation, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. - -For example, assuming you have the [User and Email data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-one-relationship/index.html.md), set an email's user ID as follows: - -```ts highlights={belongsHighlights} -// when creating an email -const email = await helloModuleService.createEmails({ - // other properties... - user_id: "123", -}) - -// when updating an email -const email = await helloModuleService.updateEmails({ - id: "321", - // other properties... - user_id: "123", -}) -``` - -In the example above, you pass the `user_id` property when creating or updating an email to specify the user it belongs to. - -### HasOne Side - -When you create a record of a data model that has one of another, pass the ID of the other data model's record in the relation property. - -For example, assuming you have the [User and Email data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-one-relationship/index.html.md), set a user's email ID as follows: - -```ts highlights={hasOneHighlights} -// when creating a user -const user = await helloModuleService.createUsers({ - // other properties... - email: "123", -}) - -// when updating a user -const user = await helloModuleService.updateUsers({ - id: "321", - // other properties... - email: "123", -}) -``` - -In the example above, you pass the `email` property when creating or updating a user to specify the email it has. - -*** - -## Manage One-to-Many Relationship - -In a one-to-many relationship, you can only manage the associations from the `belongsTo` side. - -When you create a record of the data model on the `belongsTo` side, pass the ID of the other data model's record in the `{relation}_id` property, where `{relation}` is the name of the relation property. - -For example, assuming you have the [Product and Store data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#one-to-many-relationship/index.html.md), set a product's store ID as follows: - -```ts highlights={manyBelongsHighlights} -// when creating a product -const product = await helloModuleService.createProducts({ - // other properties... - store_id: "123", -}) - -// when updating a product -const product = await helloModuleService.updateProducts({ - id: "321", - // other properties... - store_id: "123", -}) -``` - -In the example above, you pass the `store_id` property when creating or updating a product to specify the store it belongs to. - -*** - -## Manage Many-to-Many Relationship - -If your many-to-many relation is represented with a [pivotEntity](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), refer to [this section](#manage-many-to-many-relationship-with-pivotentity) instead. - -### Create Associations - -When you create a record of a data model that has a many-to-many relationship to another data model, pass an array of IDs of the other data model's records in the relation property. - -For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), set the association between products and orders as follows: - -```ts highlights={manyHighlights} -// when creating a product -const product = await helloModuleService.createProducts({ - // other properties... - orders: ["123", "321"], -}) - -// when creating an order -const order = await helloModuleService.createOrders({ - id: "321", - // other properties... - products: ["123", "321"], -}) -``` - -In the example above, you pass the `orders` property when you create a product, and you pass the `products` property when you create an order. - -### Update Associations - -When you use the `update` methods generated by the service factory, you also pass an array of IDs as the relation property's value to add new associated records. - -However, this removes any existing associations to records whose IDs aren't included in the array. - -For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), you update the product's related orders as so: - -```ts -const product = await helloModuleService.updateProducts({ - id: "123", - // other properties... - orders: ["321"], -}) -``` - -If the product was associated with an order, and you don't include that order's ID in the `orders` array, the association between the product and order is removed. - -So, to add a new association without removing existing ones, retrieve the product first to pass its associated orders when updating the product: - -```ts highlights={updateAssociationHighlights} -const product = await helloModuleService.retrieveProduct( - "123", - { - relations: ["orders"], - } -) - -const updatedProduct = await helloModuleService.updateProducts({ - id: product.id, - // other properties... - orders: [ - ...product.orders.map((order) => order.id), - "321", - ], -}) -``` - -This keeps existing associations between the product and orders, and adds a new one. - -*** - -## Manage Many-to-Many Relationship with pivotEntity - -If your many-to-many relation is represented without a [pivotEntity](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), refer to [this section](#manage-many-to-many-relationship) instead. - -If you have a many-to-many relation with a `pivotEntity` specified, make sure to pass the data model representing the pivot table to [MedusaService](https://docs.medusajs.com/learn/fundamentals/modules/service-factory/index.html.md) that your module's service extends. - -For example, assuming you have the [Order, Product, and OrderProduct models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-with-custom-columns/index.html.md), add `OrderProduct` to `MedusaService`'s object parameter: - -```ts highlights={["4"]} -class BlogModuleService extends MedusaService({ - Order, - Product, - OrderProduct, -}) {} -``` - -This will generate Create, Read, Update and Delete (CRUD) methods for the `OrderProduct` data model, which you can use to create relations between orders and products and manage the extra columns in the pivot table. - -For example: - -```ts -// create order-product association -const orderProduct = await blogModuleService.createOrderProducts({ - order_id: "123", - product_id: "123", - metadata: { - test: true, - }, -}) - -// update order-product association -const orderProduct = await blogModuleService.updateOrderProducts({ - id: "123", - metadata: { - test: false, - }, -}) - -// delete order-product association -await blogModuleService.deleteOrderProducts("123") -``` - -Since the `OrderProduct` data model belongs to the `Order` and `Product` data models, you can set its order and product as explained in the [one-to-many relationship section](#manage-one-to-many-relationship) using `order_id` and `product_id`. - -Refer to the [service factory reference](https://docs.medusajs.com/resources/service-factory-reference/index.html.md) for a full list of generated methods and their usages. - -*** - -## Retrieve Records of Relation - -The `list`, `listAndCount`, and `retrieve` methods of a module's main service accept as a second parameter an object of options. - -To retrieve the records associated with a data model's records through a relationship, pass in the second parameter object a `relations` property whose value is an array of relationship names. - -For example, assuming you have the [Order and Product data models from the previous chapter](https://docs.medusajs.com/learn/fundamentals/data-models/relationships#many-to-many-relationship/index.html.md), you retrieve a product's orders as follows: - -```ts highlights={retrieveHighlights} -const product = await blogModuleService.retrieveProducts( - "123", - { - relations: ["orders"], - } -) -``` - -In the example above, the retrieved product has an `orders` property, whose value is an array of orders associated with the product. - - -# Data Model Properties - -In this chapter, you'll learn about the different property types you can use in a data model and how to configure a data model's properties. - -## Data Model's Default Properties - -By default, Medusa creates the following properties for every data model: - -- `created_at`: A [dateTime](#dateTime) property that stores when a record of the data model was created. -- `updated_at`: A [dateTime](#dateTime) property that stores when a record of the data model was updated. -- `deleted_at`: A [dateTime](#dateTime) property that stores when a record of the data model was deleted. When you soft-delete a record, Medusa sets the `deleted_at` property to the current date. - -*** - -## Property Types - -This section covers the different property types you can define in a data model's schema using the `model` methods. - -### id - -The `id` method defines an automatically generated string ID property. The generated ID is a unique string that has a mix of letters and numbers. - -For example: - -```ts highlights={idHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - id: model.id(), - // ... -}) - -export default Post -``` - -### text - -The `text` method defines a string property. - -For example: - -```ts highlights={textHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - name: model.text(), - // ... -}) - -export default Post -``` - -### number - -The `number` method defines a number property. - -For example: - -```ts highlights={numberHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - age: model.number(), - // ... -}) - -export default Post -``` - -### float - -This property is only available after [Medusa v2.1.2](https://github.com/medusajs/medusa/releases/tag/v2.1.2). - -The `float` method defines a number property that allows for values with decimal places. - -Use this property type when it's less important to have high precision for numbers with large decimal places. Alternatively, for higher percision, use the [bigNumber property](#bignumber). - -For example: - -```ts highlights={floatHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - rating: model.float(), - // ... -}) - -export default Post -``` - -### bigNumber - -The `bigNumber` method defines a number property that expects large numbers, such as prices. - -Use this property type when it's important to have high precision for numbers with large decimal places. Alternatively, for less percision, use the [float property](#float). - -For example: - -```ts highlights={bigNumberHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - price: model.bigNumber(), - // ... -}) - -export default Post -``` - -### boolean - -The `boolean` method defines a boolean property. - -For example: - -```ts highlights={booleanHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - hasAccount: model.boolean(), - // ... -}) - -export default Post -``` - -### enum - -The `enum` method defines a property whose value can only be one of the specified values. - -For example: - -```ts highlights={enumHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - color: model.enum(["black", "white"]), - // ... -}) - -export default Post -``` - -The `enum` method accepts an array of possible string values. - -### dateTime - -The `dateTime` method defines a timestamp property. - -For example: - -```ts highlights={dateTimeHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - date_of_birth: model.dateTime(), - // ... -}) - -export default Post -``` - -### json - -The `json` method defines a property whose value is a stringified JSON object. - -For example: - -```ts highlights={jsonHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - metadata: model.json(), - // ... -}) - -export default Post -``` - -### array - -The `array` method defines an array of strings property. - -For example: - -```ts highlights={arrHightlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - names: model.array(), - // ... -}) - -export default Post -``` - -### Properties Reference - -Refer to the [Data Model Language (DML) reference](https://docs.medusajs.com/resources/references/data-model/index.html.md) for a full reference of the properties. - -*** - -## Set Primary Key Property - -To set any `id`, `text`, or `number` property as a primary key, use the `primaryKey` method. - -For example: - -```ts highlights={highlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - id: model.id().primaryKey(), - // ... -}) - -export default Post -``` - -In the example above, the `id` property is defined as the data model's primary key. - -*** - -## Property Default Value - -Use the `default` method on a property's definition to specify the default value of a property. - -For example: - -```ts highlights={defaultHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - color: model - .enum(["black", "white"]) - .default("black"), - age: model - .number() - .default(0), - // ... -}) - -export default Post -``` - -In this example, you set the default value of the `color` enum property to `black`, and that of the `age` number property to `0`. - -*** - -## Make Property Optional - -Use the `nullable` method to indicate that a property’s value can be `null`. This is useful when you want a property to be optional. - -For example: - -```ts highlights={nullableHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - price: model.bigNumber().nullable(), - // ... -}) - -export default Post -``` - -In the example above, the `price` property is configured to allow `null` values, making it optional. - -*** - -## Unique Property - -The `unique` method indicates that a property’s value must be unique in the database through a unique index. - -For example: - -```ts highlights={uniqueHighlights} -import { model } from "@medusajs/framework/utils" - -const User = model.define("user", { - email: model.text().unique(), - // ... -}) - -export default User -``` - -In this example, multiple users can’t have the same email. - -*** - -## Define Database Index on Property - -Use the `index` method on a property's definition to define a database index. - -For example: - -```ts highlights={dbIndexHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - id: model.id().primaryKey(), - name: model.text().index( - "IDX_MY_CUSTOM_NAME" - ), -}) - -export default Post -``` - -The `index` method optionally accepts the name of the index as a parameter. - -In this example, you define an index on the `name` property. - -*** - -## Define a Searchable Property - -Methods generated by the [service factory](https://docs.medusajs.com/learn/fundamentals/modules/service-factory/index.html.md) that accept filters, such as `list{ModelName}s`, accept a `q` property as part of the filters. - -When the `q` filter is passed, the data model's searchable properties are queried to find matching records. - -Use the `searchable` method on a `text` property to indicate that it's searchable. - -For example: - -```ts highlights={searchableHighlights} -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - title: model.text().searchable(), - // ... -}) - -export default Post -``` - -In this example, the `title` property is searchable. - -### Search Example - -If you pass a `q` filter to the `listPosts` method: - -```ts -const posts = await blogModuleService.listPosts({ - q: "New Products", -}) -``` - -This retrieves records that include `New Products` in their `title` property. - - -# Migrations - -In this chapter, you'll learn what a migration is and how to generate a migration or write it manually. - -## What is a Migration? - -A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations are useful when you re-use a module or you're working in a team, so that when one member of a team makes a database change, everyone else can reflect it on their side by running the migrations. - -The migration's file has a class with two methods: - -- The `up` method reflects changes on the database. -- The `down` method reverts the changes made in the `up` method. - -*** - -## Generate Migration - -Instead of you writing the migration manually, the Medusa CLI tool provides a [db:generate](https://docs.medusajs.com/resources/medusa-cli/commands/db#dbgenerate/index.html.md) command to generate a migration for a modules' data models. - -For example, assuming you have a `blog` Module, you can generate a migration for it by running the following command: - -```bash -npx medusa db:generate blog -``` - -This generates a migration file under the `migrations` directory of the Blog Module. You can then run it to reflect the changes in the database as mentioned in [this section](#run-the-migration). - -*** - -## Write a Migration Manually - -You can also write migrations manually. To do that, create a file in the `migrations` directory of the module and in it, a class that has an `up` and `down` method. The class's name should be of the format `Migration{YEAR}{MONTH}{DAY}{HOUR}{MINUTE}.ts` to ensure migrations are ran in the correct order. - -For example: - -```ts title="src/modules/blog/migrations/Migration202507021059.ts" -import { Migration } from "@mikro-orm/migrations" - -export class Migration202507021059 extends Migration { - - async up(): Promise { - this.addSql("create table if not exists \"author\" (\"id\" text not null, \"name\" text not null, \"created_at\" timestamptz not null default now(), \"updated_at\" timestamptz not null default now(), \"deleted_at\" timestamptz null, constraint \"author_pkey\" primary key (\"id\"));") - } - - async down(): Promise { - this.addSql("drop table if exists \"author\" cascade;") - } - -} -``` - -The migration class in the file extends the `Migration` class imported from `@mikro-orm/migrations`. In the `up` and `down` method of the migration class, you use the `addSql` method provided by MikroORM's `Migration` class to run PostgreSQL syntax. - -In the example above, the `up` method creates the table `author`, and the `down` method drops the table if the migration is reverted. - -Refer to [MikroORM's documentation](https://mikro-orm.io/docs/migrations#migration-class) for more details on writing migrations. - -*** - -## Run the Migration - -To run your migration, run the following command: - -This command also syncs module links. If you don't want that, use the `--skip-links` option. - -```bash -npx medusa db:migrate -``` - -This reflects the changes in the database as implemented in the migration's `up` method. - -*** - -## Rollback the Migration - -To rollback or revert the last migration you ran for a module, run the following command: - -```bash -npx medusa db:rollback blog -``` - -This rolls back the last ran migration on the Blog Module. - -### Caution: Rollback Migration before Deleting - -If you need to delete a migration file, make sure to rollback the migration first. Otherwise, you might encounter issues when generating and running new migrations. - -For example, if you delete the migration of the Blog Module, then try to create a new one, Medusa will create a brand new migration that re-creates the tables or indices. If those are still in the database, you might encounter errors. - -So, always rollback the migration before deleting it. - -*** - -## More Database Commands - -To learn more about the Medusa CLI's database commands, refer to [this CLI reference](https://docs.medusajs.com/resources/medusa-cli/commands/db/index.html.md). - - # 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. @@ -11677,663 +11478,6 @@ export default defineLink( ``` -# 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. - -## Link Table's Default Columns - -When you define a link between two data models, Medusa creates a link table in the database to store the IDs of the linked records. You can learn more about the created table in the [Module Links chapter](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md). - -In various cases, you might need to store additional data in the link table. For example, if you define a link between a `product` and a `post`, you might want to store the publish date of the product's post in the link table. - -In those cases, you can add a custom column to a link's table in the link definition. You can later set that column whenever you create or update a link between the linked records. - -*** - -## How to Add Custom Columns to a Link's Table? - -The `defineLink` function used to define a link accepts a third parameter, which is an object of options. - -To add custom columns to a link's table, pass in the third parameter of `defineLink` a `database` property: - -```ts highlights={linkHighlights} -import BlogModule from "../modules/blog" -import ProductModule from "@medusajs/medusa/product" -import { defineLink } from "@medusajs/framework/utils" - -export default defineLink( - ProductModule.linkable.product, - BlogModule.linkable.blog, - { - database: { - extraColumns: { - metadata: { - type: "json", - }, - }, - }, - } -) -``` - -This adds to the table created for the link between `product` and `blog` a `metadata` column of type `json`. - -### Database Options - -The `database` property defines configuration for the table created in the database. - -Its `extraColumns` property defines custom columns to create in the link's table. - -`extraColumns`'s value is an object whose keys are the names of the columns, and values are the column's configurations as an object. - -### Column Configurations - -The column's configurations object accepts the following properties: - -- `type`: The column's type.

Use this property when specifying the `entity` property in Query's `graph` method. - -For example: - -```ts highlights={retrieveHighlights} -import productPostLink from "../links/product-post" - -// ... - -const { data } = await query.graph({ - entity: productPostLink.entryPoint, - fields: ["metadata", "product.*", "post.*"], - filters: { - product_id: "prod_123", - }, -}) -``` - -This retrieves the product of id `prod_123` and its linked `post` records. - -In the `fields` array you pass `metadata`, which is the custom column to retrieve of the link. - -*** - -## Update Custom Column's Value - -Link's `create` method updates a link's data if the link between the specified records already exists. - -So, to update the value of a custom column in a created link, use the `create` method again passing it a new value for the custom column. - -For example: - -```ts -await link.create({ - [Modules.PRODUCT]: { - product_id: "123", - }, - [BLOG_MODULE]: { - post_id: "321", - }, - data: { - metadata: { - test: false, - }, - }, -}) -``` - - -# Data Model Relationships - -In this chapter, you’ll learn how to define relationships between data models in your module. - -## What is a Relationship Property? - -A relationship property defines an association in the database between two models. It's created using the Data Model Language (DML) methods, such as `hasOne` or `belongsTo`. - -When you generate a migration for these data models, the migrations include foreign key columns or pivot tables, based on the relationship's type. - -You want to create a relation between data models in the same module. - -You want to create a relationship between data models in different modules. Use module links instead. - -*** - -## One-to-One Relationship - -A one-to-one relationship indicates that one record of a data model belongs to or is associated with another. - -To define a one-to-one relationship, create relationship properties in the data models using the following methods: - -1. `hasOne`: indicates that the model has one record of the specified model. -2. `belongsTo`: indicates that the model belongs to one record of the specified model. - -For example: - -```ts highlights={oneToOneHighlights} -import { model } from "@medusajs/framework/utils" - -const User = model.define("user", { - id: model.id().primaryKey(), - email: model.hasOne(() => Email), -}) - -const Email = model.define("email", { - id: model.id().primaryKey(), - user: model.belongsTo(() => User, { - mappedBy: "email", - }), -}) -``` - -In the example above, a user has one email, and an email belongs to one user. - -The `hasOne` and `belongsTo` methods accept a function as the first parameter. The function returns the associated data model. - -The `belongsTo` method also requires passing as a second parameter an object with the property `mappedBy`. Its value is the name of the relationship property in the other data model. - -### Optional Relationship - -To make the relationship optional on the `hasOne` or `belongsTo` side, use the `nullable` method on either property as explained in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties#make-property-optional/index.html.md). - -### One-sided One-to-One Relationship - -If the one-to-one relationship is only defined on one side, pass `undefined` to the `mappedBy` property in the `belongsTo` method. - -For example: - -```ts highlights={oneToOneUndefinedHighlights} -import { model } from "@medusajs/framework/utils" - -const User = model.define("user", { - id: model.id().primaryKey(), -}) - -const Email = model.define("email", { - id: model.id().primaryKey(), - user: model.belongsTo(() => User, { - mappedBy: undefined, - }), -}) -``` - -### One-to-One Relationship in the Database - -When you generate the migrations of data models that have a one-to-one relationship, the migration adds to the table of the data model that has the `belongsTo` property: - -1. A column of the format `{relation_name}_id` to store the ID of the record of the related data model. For example, the `email` table will have a `user_id` column. -2. A foreign key on the `{relation_name}_id` column to the table of the related data model. - -![Diagram illustrating the relation between user and email records in the database](https://res.cloudinary.com/dza7lstvk/image/upload/v1726733492/Medusa%20Book/one-to-one_cj5np3.jpg) - -*** - -## One-to-Many Relationship - -A one-to-many relationship indicates that one record of a data model has many records of another data model. - -To define a one-to-many relationship, create relationship properties in the data models using the following methods: - -1. `hasMany`: indicates that the model has more than one record of the specified model. -2. `belongsTo`: indicates that the model belongs to one record of the specified model. - -For example: - -```ts highlights={oneToManyHighlights} -import { model } from "@medusajs/framework/utils" - -const Store = model.define("store", { - id: model.id().primaryKey(), - products: model.hasMany(() => Product), -}) - -const Product = model.define("product", { - id: model.id().primaryKey(), - store: model.belongsTo(() => Store, { - mappedBy: "products", - }), -}) -``` - -In this example, a store has many products, but a product belongs to one store. - -### Optional Relationship - -To make the relationship optional on the `belongsTo` side, use the `nullable` method on the property as explained in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties#make-property-optional/index.html.md). - -### One-to-Many Relationship in the Database - -When you generate the migrations of data models that have a one-to-many relationship, the migration adds to the table of the data model that has the `belongsTo` property: - -1.

A function that returns the associated data model. -2. An object of optional configuration. Only one of the data models in the relation can define the `pivotTable`, `joinColumn`, and `inverseJoinColumn` configurations, and it's considered the owner data model. The object can accept the following properties: - - `mappedBy`: The name of the relationship property in the other data model. If not set, the property's name is inferred from the associated data model's name. - - `pivotTable`: The name of the pivot table created in the database for the many-to-many relation. If not set, the pivot table is inferred by combining the names of the data models' tables in alphabetical order, separating them by `_`, and pluralizing the last name. For example, `order_products`. - - `joinColumn`: The name of the column in the pivot table that points to the owner model's primary key. - - `inverseJoinColumn`: The name of the column in the pivot table that points to the owned model's primary key. - -The `pivotTable`, `joinColumn`, and `inverseJoinColumn` properties are only available after [Medusa v2.0.7](https://github.com/medusajs/medusa/releases/tag/v2.0.7). - -Following [Medusa v2.1.0](https://github.com/medusajs/medusa/releases/tag/v2.1.0), if `pivotTable`, `joinColumn`, and `inverseJoinColumn` aren't specified on either model, the owner is decided based on alphabetical order. So, in the example above, the `Order` data model would be the owner. - -In this example, an order is associated with many products, and a product is associated with many orders. Since the `pivotTable`, `joinColumn`, and `inverseJoinColumn` configurations are defined on the order, it's considered the owner data model. - -### Many-to-Many Relationship in the Database - -When you generate the migrations of data models that have a many-to-many relationship, the migration adds a new pivot table. Its name is either the name you specify in the `pivotTable` configuration or the inferred name combining the names of the data models' tables in alphabetical order, separating them by `_`, and pluralizing the last name. For example, `order_products`. - -The pivot table has a column with the name `{data_model}_id` for each of the data model's tables. It also has foreign keys on each of these columns to their respective tables. - -The pivot table has columns with foreign keys pointing to the primary key of the associated tables. The column's name is either: - -- The value of the `joinColumn` configuration for the owner table, and the `inverseJoinColumn` configuration for the owned table; -- Or the inferred name `{table_name}_id`. - -![Diagram illustrating the relation between order and product records in the database](https://res.cloudinary.com/dza7lstvk/image/upload/v1726734269/Medusa%20Book/many-to-many_fzy5pq.jpg) - -### Many-To-Many with Custom Columns - -To add custom columns to the pivot table between two data models having a many-to-many relationship, you must define a new data model that represents the pivot table. - -For example: - -```ts highlights={manyToManyColumnHighlights} -import { model } from "@medusajs/framework/utils" - -export const Order = model.define("order_test", { - id: model.id().primaryKey(), - products: model.manyToMany(() => Product, { - pivotEntity: () => OrderProduct, - }), -}) - -export const Product = model.define("product_test", { - id: model.id().primaryKey(), - orders: model.manyToMany(() => Order), -}) - -export const OrderProduct = model.define("orders_products", { - id: model.id().primaryKey(), - order: model.belongsTo(() => Order, { - mappedBy: "products", - }), - product: model.belongsTo(() => Product, { - mappedBy: "orders", - }), - metadata: model.json().nullable(), -}) -``` - -The `Order` and `Product` data models have a many-to-many relationship. To add extra columns to the created pivot table, you pass a `pivotEntity` option to the `products` relation in `Order` (since `Order` is the owner). The value of `pivotEntity` is a function that returns the data model representing the pivot table. - -The `OrderProduct` model defines, aside from the ID, the following properties: - -- `order`: A relation that indicates this model belongs to the `Order` data model. You set the `mappedBy` option to the many-to-many relation's name in the `Order` data model. -- `product`: A relation that indicates this model belongs to the `Product` data model.

Unless you made changes to the dependencies, you can skip this section. + +In the `package.json` file you must have the Medusa dependencies as `devDependencies` and `peerDependencies`. In addition, you must have `@swc/core` as a `devDependency`, as it's used by the plugin CLI tools. + +For example, assuming `2.5.0` is the latest Medusa version: + +```json title="package.json" +{ + "devDependencies": { + "@medusajs/admin-sdk": "2.5.0", + "@medusajs/cli": "2.5.0", + "@medusajs/framework": "2.5.0", + "@medusajs/medusa": "2.5.0", + "@medusajs/test-utils": "2.5.0", + "@medusajs/ui": "4.0.4", + "@medusajs/icons": "2.5.0", + "@swc/core": "1.5.7", + }, + "peerDependencies": { + "@medusajs/admin-sdk": "2.5.0", + "@medusajs/cli": "2.5.0", + "@medusajs/framework": "2.5.0", + "@medusajs/test-utils": "2.5.0", + "@medusajs/medusa": "2.5.0", + "@medusajs/ui": "4.0.3", + "@medusajs/icons": "2.5.0", + } +} +``` + +### Package Exports + +Your plugin project will already have the exports mentioned in this section. Unless you made changes to the exports or you created your plugin before [Medusa v2.7.0](https://github.com/medusajs/medusa/releases/tag/v2.7.0), you can skip this section. + +In the `package.json` file, make sure your plugin has the following exports: + +```json title="package.json" +{ + "exports": { + "./package.json": "./package.json", + "./workflows": "./.medusa/server/src/workflows/index.js", + "./.medusa/server/src/modules/*": "./.medusa/server/src/modules/*/index.js", + "./providers/*": "./.medusa/server/src/providers/*/index.js", + "./admin": { + "import": "./.medusa/server/src/admin/index.mjs", + "require": "./.medusa/server/src/admin/index.js", + "default": "./.medusa/server/src/admin/index.js" + }, + "./*": "./.medusa/server/src/*.js" + } +} +``` + +Aside from the `./package.json`, `./providers`, and `./admin`, these exports are only a recommendation. You can cherry-pick the files and directories you want to export. + +The plugin exports the following files and directories: + +- `./package.json`: The `package.json` file. Medusa needs to access the `package.json` when registering the plugin. +- `./workflows`: The workflows exported in `./src/workflows/index.ts`. +- `./.medusa/server/src/modules/*`: The definition file of modules. This is useful if you create links to the plugin's modules in the Medusa application. +- `./providers/*`: The definition file of module providers. This is useful if your plugin includes a module provider, allowing you to register the plugin's providers in Medusa applications. Learn more in the [Create Module Providers](#create-module-providers) section. +- `./admin`: The admin extensions exported in `./src/admin/index.ts`. +- `./*`: Any other files in the plugin's `src` directory. + +*** + +## 3. Publish Plugin Locally for Development and Testing + +Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. + +### Publish and Install Local Package + +### Prerequisites + +- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) + +The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. + +To publish the plugin to the local registry, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:publish +``` + +This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. + +Next, navigate to your Medusa application: + +```bash title="Medusa application" +cd ~/path/to/medusa-app +``` + +Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. + +Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: + +```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" +npm install --save-dev yalc +``` + +After that, run the following Medusa CLI command to install the plugin: + +```bash title="Medusa application" +npx medusa plugin:add @myorg/plugin-name +``` + +Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. + +### Register Plugin in Medusa Application + +After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. + +Add the plugin to the `plugins` array in the `medusa-config.ts` file: + +```ts title="medusa-config.ts" highlights={pluginHighlights} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: {}, + }, + ], +}) +``` + +The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. + +#### Pass Module Options through Plugin + +Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. + +For example: + +```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: { + apiKey: true, + }, + }, + ], +}) +``` + +The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). + +### Watch Plugin Changes During Development + +While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. + +To do that, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:develop +``` + +This command will: + +- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. +- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. + +### Start Medusa Application + +You can start your Medusa application's development server to test out your plugin: + +```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" +npm run dev +``` + +While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. + +*** + +## 4. Create Customizations in the Plugin + +You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. + +- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) +- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) +- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) +- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) +- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) +- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) +- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) +- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) +- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) + +While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). + +### Generating Migrations for Modules + +During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: + +```plain title="Plugin project" +DB_USERNAME=postgres +DB_PASSWORD=123... +DB_HOST=localhost +DB_PORT=5432 +DB_NAME=db_name +``` + +You can add these environment variables in a `.env` file in your plugin project. The variables are: + +- `DB_USERNAME`: The username of the PostgreSQL user to connect to the database. +- `DB_PASSWORD`: The password of the PostgreSQL user to connect to the database. +- `DB_HOST`: The host of the PostgreSQL database. Typically, it's `localhost` if you're running the database locally. +- `DB_PORT`: The port of the PostgreSQL database. Typically, it's `5432` if you're running the database locally. +- `DB_NAME`: The name of the PostgreSQL database to connect to. + +Then, run the following command in your plugin project to generate migrations for the modules in your plugin: + +```bash title="Plugin project" +npx medusa plugin:db:generate +``` + +This command generates migrations for all modules in the plugin. + +Finally, run these migrations on the Medusa application that the plugin is installed in using the `db:migrate` command: + +```bash title="Medusa application" +npx medusa db:migrate +``` + +The migrations in your application, including your plugin, will run and update the database. + +### Importing Module Resources + +In the [Prepare Plugin](#2-prepare-plugin) section, you learned about [exported resources](#package-exports) in your plugin. + +These exports allow you to import your plugin resources in your Medusa application, including workflows, links and modules. + +For example, to import the plugin's workflow in your Medusa application: + +`@myorg/plugin-name` is the plugin package's name. + +```ts +import { Workflow1, Workflow2 } from "@myorg/plugin-name/workflows" +import BlogModule from "@myorg/plugin-name/modules/blog" +// import other files created in plugin like ./src/types/blog.ts +import BlogType from "@myorg/plugin-name/types/blog" +``` + +### Create Module Providers + +The [exported resources](#package-exports) also allow you to import module providers in your plugin and register them in the Medusa application's configuration. A module provider is a module that provides the underlying logic or integration related to a commerce or Infrastructure Module. + +For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/index.html.md) called `my-notification`, you can register it in your Medusa application's configuration like this: + +`@myorg/plugin-name` is the plugin package's name. + +```ts highlights={[["9"]]} title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + { + resolve: "@myorg/plugin-name/providers/my-notification", + id: "my-notification", + options: { + channels: ["email"], + // provider options... + }, + }, + ], + }, + }, + ], +}) +``` + +You pass to `resolve` the path to the provider relative to the plugin package. So, in this example, the `my-notification` provider is located in `./src/providers/my-notification/index.ts` of the plugin. + +To learn how to create module providers, refer to the following guides: + +- [File Module Provider](https://docs.medusajs.com/resources/references/file-provider-module/index.html.md) +- [Notification Module Provider](https://docs.medusajs.com/resources/references/notification-provider-module/index.html.md) +- [Auth Module Provider](https://docs.medusajs.com/resources/references/auth/provider/index.html.md) +- [Payment Module Provider](https://docs.medusajs.com/resources/references/payment/provider/index.html.md) +- [Fulfillment Module Provider](https://docs.medusajs.com/resources/references/fulfillment/provider/index.html.md) +- [Tax Module Provider](https://docs.medusajs.com/resources/references/tax/provider/index.html.md) + +*** + +## 5. Publish Plugin to NPM + +Make sure to add the keywords mentioned in the [Package Keywords](#package-keywords) section in your plugin's `package.json` file. + +Medusa's CLI tool provides a command that bundles your plugin to be published to npm. Once you're ready to publish your plugin publicly, run the following command in your plugin project: + +```bash +npx medusa plugin:build +``` + +The command will compile an output in the `.medusa/server` directory. + +You can now publish the plugin to npm using the [NPM CLI tool](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm). Run the following command to publish the plugin to npm: + +```bash +npm publish +``` + +If you haven't logged in before with your NPM account, you'll be asked to log in first. Then, your package is published publicly to be used in any Medusa application. + +### Install Public Plugin in Medusa Application + +You install a plugin that's published publicly using your package manager. For example: + +```bash npm2yarn +npm install @myorg/plugin-name +``` + +Where `@myorg/plugin-name` is the name of your plugin as published on NPM. + +Then, register the plugin in your Medusa application's configurations as explained in [this section](#register-plugin-in-medusa-application). + +*** + +## Update a Published Plugin + +To update the Medusa dependencies in a plugin, refer to [this documentation](https://docs.medusajs.com/learn/update#update-plugin-project/index.html.md). + +If you've published a plugin and you've made changes to it, you'll have to publish the update to NPM again. + +First, run the following command to change the version of the plugin: + +```bash +npm version +``` + +Where `` indicates the type of version update you’re publishing. For example, it can be `major` or `minor`. Refer to the [npm version documentation](https://docs.npmjs.com/cli/v10/commands/npm-version) for more information. + +Then, re-run the same commands for publishing a plugin: + +```bash +npx medusa plugin:build +npm publish +``` + +This will publish an updated version of your plugin under a new version. + + # Commerce Modules In this chapter, you'll learn about Medusa's Commerce Modules. @@ -13732,6 +13544,259 @@ export default async function helloWorldLoader({ ``` +# Module Isolation + +In this chapter, you'll learn how modules are isolated, and what that means for your custom development. + +- Modules can't access resources, such as services or data models, from other modules. +- Use [Module Links](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) to extend an existing module's data models, and [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md) to retrieve data across modules. +- Use [workflows](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) to build features that depend on functionalities from different modules. + +## How are Modules Isolated? + +A module is unaware of any resources other than its own, such as services or data models.

Its value can be a boolean or a string. + +By default, `skipOnPermanentFailure` is disabled. When it's enabled, the workflow's status is set to `skipped` instead of `failed`.

Third-Party Service Authenticate Flow + +This authentication flow authenticates the user with a third-party service, such as Google. + +[How to authenticate customer with a third-party provider in the storefront.](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/storefront-development/customers/third-party-login/index.html.md). + +It requires the following steps: + +![Diagram showcasing the authentication flow between the frontend, Medusa application, and third-party service](https://res.cloudinary.com/dza7lstvk/image/upload/v1725528159/Medusa%20Resources/Third_Party_Auth_tvf4ng.jpg) + +1. Authenticate the user with the [Auth Route](#login-route). +2. The auth route returns a URL to authenticate with third-party service, such as login with Google. The frontend (such as a storefront), when it receives a `location` property in the response, must redirect to the returned location. +3. Once the authentication with the third-party service finishes, it redirects back to the frontend with a `code` query parameter. So, make sure your third-party service is configured to redirect to your frontend page after successful authentication. +4. The frontend sends a request to the [Validate Callback Route](#validate-callback-route) passing it the query parameters received from the third-party service, such as the `code` and `state` query parameters. +5. If the callback validation is successful, the frontend receives the authentication token. +6. Decode the received token in the frontend using tools like [react-jwt](https://www.npmjs.com/package/react-jwt). + - If the decoded data has an `actor_id` property, then the user is already registered. So, use this token for subsequent authenticated requests. + - If not, follow the rest of the steps. +7. The frontend uses the authentication token to create the user with their respective API route. + - For example, for customers you would use the [Create Customer API route](https://docs.medusajs.com/api/store#customers_postcustomers). + - For admin users, you accept an invite using the [Accept Invite API route](https://docs.medusajs.com/api/admin#invites_postinvitesaccept) +8. The frontend sends a request to the [Refresh Token Route](#refresh-token-route) to retrieve a new token with the user information populated. + +*** + +## Register Route + +The Medusa application defines an API route at `/auth/{actor_type}/{provider}/register` that creates an auth identity for an actor type, such as a `customer`. It returns a JWT token that you pass to an API route that creates the user. + +```bash +curl -X POST http://localhost:9000/auth/{actor_type}/{providers}/register +-H 'Content-Type: application/json' \ +--data-raw '{ + "email": "Whitney_Schultz@gmail.com" + // ... +}' +``` + +This API route is useful for providers like `emailpass` that uses custom logic to authenticate a user. For authentication providers that authenticate with third-party services, such as Google, use the [Auth Route](#login-route) instead. + +For example, if you're registering a customer, you: + +1. Send a request to `/auth/customer/emailpass/register` to retrieve the registration JWT token. +2. Send a request to the [Create Customer API route](https://docs.medusajs.com/api/store#customers_postcustomers) to create the customer, passing the [JWT token in the header](https://docs.medusajs.com/api/store#authentication). + +### Path Parameters + +Its path parameters are: + +- `{actor_type}`: the actor type of the user you're authenticating. For example, `customer`. +- `{provider}`: the auth provider to handle the authentication. For example, `emailpass`. + +### Request Body Parameters + +This route accepts in the request body the data that the specified authentication provider requires to handle authentication. + +For example, the EmailPass provider requires an `email` and `password` fields in the request body. + +### Response Fields + +If the authentication is successful, you'll receive a `token` field in the response body object: + +```json +{ + "token": "..." +} +``` + +Use that token in the header of subsequent requests to send authenticated requests. + +### Handling Existing Identities + +An auth identity with the same email may already exist in Medusa. This can happen if: + +- Another actor type is using that email. For example, an admin user is trying to register as a customer. +- The same email belongs to a record of the same actor type. For example, another customer has the same email. + +In these scenarios, the Register Route will return an error instead of a token: + +```json +{ + "type": "unauthorized", + "message": "Identity with email already exists" +} +``` + +To handle these scenarios, you can use the [Login Route](#login-route) to validate that the email and password match the existing identity. If so, you can allow the admin user, for example, to register as a customer. + +Otherwise, if the email and password don't match the existing identity, such as when the email belongs to another customer, the [Login Route](#login-route) returns an error: + +```json +{ + "type": "unauthorized", + "message": "Invalid email or password" +} +``` + +You can show that error message to the customer. + +*** + +## Login Route + +The Medusa application defines an API route at `/auth/{actor_type}/{provider}` that authenticates a user of an actor type.

It calls the `update` method of the specified authentication provider. +The `Exchange` data model has a `difference_due` property that stores the outstanding amount. -For example: +|Condition|Result| +|---|---|---| +|\`difference\_due \< 0\`|Merchant owes the customer a refund of the | +|\`difference\_due > 0\`|Merchant requires additional payment from the customer of the | +|\`difference\_due = 0\`|No payment processing is required.| -```ts -const { success } = await authModuleService.updateProvider( - "emailpass", - // passed to the auth provider - { - entity_id: "user@example.com", - password: "supersecret", - } -) - -if (success) { - // password reset successfully -} -``` - -The method accepts as a first parameter the ID of the provider, and as a second parameter the data necessary to reset the password. - -In the example above, you use the `emailpass` provider, so you have to pass an object having an `email` and `password` properties. - -If the returned `success` property is `true`, the password has reset successfully. - - -# How to Use Authentication Routes - -In this document, you'll learn about the authentication routes and how to use them to create and log-in users, and reset their password. - -These routes are added by Medusa's HTTP layer, not the Auth Module. - -## Types of Authentication Flows - -### 1. Basic Authentication Flow - -This authentication flow doesn't require validation with third-party services. - -[How to register customer in storefront using basic authentication flow](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/storefront-development/customers/register/index.html.md). - -The steps are: - -![Diagram showcasing the basic authentication flow between the frontend and the Medusa application](https://res.cloudinary.com/dza7lstvk/image/upload/v1725539370/Medusa%20Resources/basic-auth-routes_pgpjch.jpg) - -1. Register the user with the [Register Route](#register-route). -2. Use the authentication token to create the user with their respective API route. - - For example, for customers you would use the [Create Customer API route](https://docs.medusajs.com/api/store#customers_postcustomers). - - For admin users, you accept an invite using the [Accept Invite API route](https://docs.medusajs.com/api/admin#invites_postinvitesaccept) -3. Authenticate the user with the [Auth Route](#login-route). - -After registration, you only use the [Auth Route](#login-route) for subsequent authentication. - -To handle errors related to existing identities, refer to [this section](#handling-existing-identities). - -### 2. Third-Party Service Authenticate Flow - -This authentication flow authenticates the user with a third-party service, such as Google. - -[How to authenticate customer with a third-party provider in the storefront.](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/storefront-development/customers/third-party-login/index.html.md). - -It requires the following steps: - -![Diagram showcasing the authentication flow between the frontend, Medusa application, and third-party service](https://res.cloudinary.com/dza7lstvk/image/upload/v1725528159/Medusa%20Resources/Third_Party_Auth_tvf4ng.jpg) - -1. Authenticate the user with the [Auth Route](#login-route). -2. The auth route returns a URL to authenticate with third-party service, such as login with Google. The frontend (such as a storefront), when it receives a `location` property in the response, must redirect to the returned location. -3. Once the authentication with the third-party service finishes, it redirects back to the frontend with a `code` query parameter. So, make sure your third-party service is configured to redirect to your frontend page after successful authentication. -4. The frontend sends a request to the [Validate Callback Route](#validate-callback-route) passing it the query parameters received from the third-party service, such as the `code` and `state` query parameters. -5. If the callback validation is successful, the frontend receives the authentication token. -6. Decode the received token in the frontend using tools like [react-jwt](https://www.npmjs.com/package/react-jwt). - - If the decoded data has an `actor_id` property, then the user is already registered. So, use this token for subsequent authenticated requests. - - If not, follow the rest of the steps. -7. The frontend uses the authentication token to create the user with their respective API route. - - For example, for customers you would use the [Create Customer API route](https://docs.medusajs.com/api/store#customers_postcustomers). - - For admin users, you accept an invite using the [Accept Invite API route](https://docs.medusajs.com/api/admin#invites_postinvitesaccept) -8. The frontend sends a request to the [Refresh Token Route](#refresh-token-route) to retrieve a new token with the user information populated. +Any payment or refund made is stored in the [Transaction data model](https://docs.medusajs.com/references/order/models/OrderTransaction/index.html.md). *** -## Register Route +## How Exchanges Impact an Order’s Version -The Medusa application defines an API route at `/auth/{actor_type}/{provider}/register` that creates an auth identity for an actor type, such as a `customer`.

For example, `reg_123` or `usd`. - -Only `region_id` and `currency_code` are supported as an `attribute` at the moment. - -The `is_tax_inclusive` property indicates whether tax-inclusivity is enabled in the specified context. - -For example: - -```json -{ - "attribute": "currency_code", - "value": "USD", - "is_tax_inclusive": true, -} -``` - -In this example, tax-inclusivity is enabled for the `USD` currency code. - -*** - -## Tax-Inclusive Pricing in Price Calculation - -### Tax Context - -As mentioned in the [Price Calculation documentation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#calculation-context/index.html.md), The `calculatePrices` method accepts as a parameter a calculation context. - -To get accurate tax results, pass the `region_id` and / or `currency_code` in the calculation context. - -### Returned Tax Properties - -The `calculatePrices` method returns two properties related to tax-inclusivity: - -Learn more about the returned properties in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#returned-price-object/index.html.md). - -- `is_calculated_price_tax_inclusive`: Whether the selected `calculated_price` is tax-inclusive. -- `is_original_price_tax_inclusive` : Whether the selected `original_price` is tax-inclusive. - -A price is considered tax-inclusive if: - -1. It belongs to the region or currency code specified in the calculation context; -2. and the region or currency code has a price preference with `is_tax_inclusive` enabled. - -### Tax Context Precedence - -A region’s price preference’s `is_tax_inclusive`'s value takes higher precedence in determining whether a price is tax-inclusive if: - -- both the `region_id` and `currency_code` are provided in the calculation context; -- the selected price belongs to the region; -- and the region has a price preference - - -# Promotion Actions - -In this document, you’ll learn about promotion actions and how they’re computed using the [computeActions method](https://docs.medusajs.com/references/promotion/computeActions/index.html.md). - -## computeActions Method - -The Promotion Module's main service has a [computeActions method](https://docs.medusajs.com/references/promotion/computeActions/index.html.md) that returns an array of actions to perform on a cart when one or more promotions are applied. - -Actions inform you what adjustment must be made to a cart item or shipping method. Each action is an object having the `action` property indicating the type of action. - -*** - -## Action Types - -### `addItemAdjustment` Action - -The `addItemAdjustment` action indicates that an adjustment must be made to an item. For example, removing $5 off its amount. - -This action has the following format: - -```ts -export interface AddItemAdjustmentAction { - action: "addItemAdjustment" - item_id: string - amount: number - code: string - description?: string -} -``` - -This action means that a new record should be created of the `LineItemAdjustment` data model in the Cart Module, or `OrderLineItemAdjustment` data model in the Order Module. - -Refer to [this reference](https://docs.medusajs.com/references/promotion/interfaces/promotion.AddItemAdjustmentAction/index.html.md) for details on the object’s properties. - -### `removeItemAdjustment` Action - -The `removeItemAdjustment` action indicates that an adjustment must be removed from a line item. For example, remove the $5 discount. - -The `computeActions` method accepts any previous item adjustments in the `items` property of the second parameter. - -This action has the following format: - -```ts -export interface RemoveItemAdjustmentAction { - action: "removeItemAdjustment" - adjustment_id: string - description?: string - code: string -} -``` - -This action means that a new record should be removed of the `LineItemAdjustment` (or `OrderLineItemAdjustment`) with the specified ID in the `adjustment_id` property. - -Refer to [this reference](https://docs.medusajs.com/references/promotion/interfaces/promotion.RemoveItemAdjustmentAction/index.html.md) for details on the object’s properties. - -### `addShippingMethodAdjustment` Action - -The `addShippingMethodAdjustment` action indicates that an adjustment must be made on a shipping method.

The budget limits how many times the promotion can be used. - -There are two types of budgets: - -- `spend`: An amount that, when crossed, the promotion becomes unusable. For example, if the amount limit is set to `$100`, and the total amount of usage of this promotion crosses that threshold, the promotion can no longer be applied. -- `usage`: The number of times that a promotion can be used. For example, if the usage limit is set to `10`, the promotion can be used only 10 times by customers. After that, it can no longer be applied. - -![A diagram showcasing the relation between the Campaign and CampaignBudget data models](https://res.cloudinary.com/dza7lstvk/image/upload/v1709899463/Medusa%20Resources/campagin-budget_rvqlmi.jpg) - - -# Promotion Concepts - -In this guide, you’ll learn about the main promotion and rule concepts in the Promotion Module. - -Refer to this [Medusa Admin User Guide](https://docs.medusajs.com/user-guide/promotions/index.html.md) to learn how to manage promotions using the dashboard. - -## What is a Promotion? - -A promotion, represented by the [Promotion data model](https://docs.medusajs.com/references/promotion/models/Promotion/index.html.md), is a discount that can be applied on cart items, shipping methods, or entire orders. - -A promotion has two types: - -- `standard`: A standard promotion with rules. -- `buyget`: “A buy X get Y” promotion with rules. - -|\`standard\`|\`buyget\`| -|---|---| -|A coupon code that gives customers 10% off their entire order.|Buy two shirts and get another for free.| -|A coupon code that gives customers $15 off any shirt in their order.|Buy two shirts and get 10% off the entire order.| -|A discount applied automatically for VIP customers that removes 10% off their shipping method’s amount.|Spend $100 and get free shipping.| - -The Medusa Admin UI may not provide a way to create each of these promotion examples. However, they are supported by the Promotion Module and Medusa's workflows and API routes. - -*** - -## Promotion Rules - -A promotion can be restricted by a set of rules, each rule is represented by the [PromotionRule data model](https://docs.medusajs.com/references/promotion/models/PromotionRule/index.html.md). - -For example, you can create a promotion that only customers of the `VIP` customer group can use. - -![A diagram showcasing the relation between Promotion and PromotionRule](https://res.cloudinary.com/dza7lstvk/image/upload/v1709833196/Medusa%20Resources/promotion-promotion-rule_msbx0w.jpg) - -A `PromotionRule`'s `attribute` property indicates the property's name to which this rule is applied. For example, `customer_group_id`. - -The expected value for the attribute is stored in the `PromotionRuleValue` data model. So, a rule can have multiple values. - -When testing whether a promotion can be applied to a cart, the rule's `attribute` property and its values are tested on the cart itself. - -For example, the cart's customer must be part of the customer group(s) indicated in the promotion rule's value. - -### Flexible Rules - -The `PromotionRule`'s `operator` property adds more flexibility to the rule’s condition rather than simple equality (`eq`). - -For example, to restrict the promotion to only `VIP` and `B2B` customer groups: - -- Add a `PromotionRule` record with its `attribute` property set to `customer_group_id` and `operator` property to `in`. -- Add two `PromotionRuleValue` records associated with the rule: one with the value `VIP` and the other `B2B`. - -![A diagram showcasing the relation between PromotionRule and PromotionRuleValue when a rule has multiple values](https://res.cloudinary.com/dza7lstvk/image/upload/v1709897383/Medusa%20Resources/promotion-promotion-rule-multiple_hctpmt.jpg) - -In this case, a customer’s group must be in the `VIP` and `B2B` set of values to use the promotion. - -*** - -## How to Apply Rules on a Promotion? - -### Using Workflows - -If you're managing promotions using [Medusa's workflows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/medusa-workflows-reference/index.html.md) or the API routes that use them, you can specify rules for the promotion or its [application method](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/application-method/index.html.md). - -For example, if you're creating a promotion using the [createPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/createPromotionsWorkflow/index.html.md): - -```ts -const { result } = await createPromotionsWorkflow(container) - .run({ - input: { - promotionsData: [{ - code: "10OFF", - type: "standard", - status: "active", - application_method: { - type: "percentage", - target_type: "items", - allocation: "across", - value: 10, - currency_code: "usd", - }, - rules: [ - { - attribute: "customer.group.id", - operator: "eq", - values: [ - "cusgrp_123", - ], - }, - ], - }], - }, - }) -``` - -In this example, the promotion is restricted to customers with the `cusgrp_123` customer group. - -### Using Promotion Module's Service - -For most use cases, it's recommended to use [workflows](#using-workflows) instead of directly using the module's service. - -If you're managing promotions using the Promotion Module's service, you can specify rules for the promotion or its [application method](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/application-method/index.html.md) in its methods. - -For example, if you're creating a promotion with the [createPromotions](https://docs.medusajs.com/references/promotion/createPromotions/index.html.md) method: - -```ts -const promotions = await promotionModuleService.createPromotions([ - { - code: "50OFF", - type: "standard", - status: "active", - application_method: { - type: "percentage", - target_type: "items", - value: 50, - }, - rules: [ - { - attribute: "customer.group.id", - operator: "eq", - values: [ - "cusgrp_123", - ], - }, - ], - }, -]) -``` - -In this example, the promotion is restricted to customers with the `cusgrp_123` customer group. - -### How is the Promotion Rule Applied? - -A promotion is applied on a resource if its attributes match the promotion's rules. - -For example, consider you have the following promotion with a rule that restricts the promotion to a specific customer: - -```json -{ - "code": "10OFF", - "type": "standard", - "status": "active", - "application_method": { - "type": "percentage", - "target_type": "items", - "allocation": "across", - "value": 10, - "currency_code": "usd" - }, - "rules": [ - { - "attribute": "customer_id", - "operator": "eq", - "values": [ - "cus_123" - ] - } - ] -} -``` - -When you try to apply this promotion on a cart, the cart's `customer_id` is compared to the promotion rule's value based on the specified operator. So, the promotion will only be applied if the cart's `customer_id` is equal to `cus_123`. - - -# Links between Promotion Module and Other Modules - -This document showcases the module links defined between the Promotion Module and other Commerce Modules. +This document showcases the module links defined between the Store Module and other Commerce Modules. ## Summary -The Promotion Module has the following links to other modules: +The Store Module has the following links to other modules: Read-only links are used to query data across modules, but the relations aren't stored in a pivot table in the database. |First Data Model|Second Data Model|Type|Description| |---|---|---|---| -|Cart|Promotion|Stored - many-to-many|Learn more| -|LineItemAdjustment|Promotion|Read-only - has one|Learn more| -|Order|Promotion|Stored - many-to-many|Learn more| +|StoreCurrency|Currency|Read-only - has many|Learn more| *** -## Cart Module +## Currency Module -A promotion can be applied on line items and shipping methods of a cart.

Then, in the method, you emit the events in the group, then clear the grouped events using the `clearGroupedEvents` which you'll learn about next. + +To add events to the grouped events map, you can do it in the `emit` method: + +```ts title="src/modules/my-event/service.ts" +class MyEventService extends AbstractEventBusModuleService { + // ... + async emit(data: Message | Message[], options: Record): Promise { + const events = Array.isArray(data) ? data : [data] + + for (const event of events) { + console.log(`Received the event ${event.name} with data ${event.data}`) + + if (event.metadata.eventGroupId) { + const groupedEvents = this.groupedEventsMap_.get( + event.metadata.eventGroupId + ) || [] + + groupedEvents.push(event) + + this.groupedEventsMap_.set(event.metadata.eventGroupId, groupedEvents) + continue + } + + // TODO push the event somewhere + } + } +} +``` + +### clearGroupedEvents Method + +If your Event Module supports grouped events, this method is used to remove the events of a group. + +For example: + +```ts title="src/modules/my-event/service.ts" +class MyEventService extends AbstractEventBusModuleService { + // from previous section + protected groupedEventsMap_: Map + + async clearGroupedEvents(eventGroupId: string): Promise { + this.groupedEventsMap_.delete(eventGroupId) + } + + // ... +} +``` + +The method accepts the group's name as a parameter. + +In the method, you delete the group from the `groupedEventsMap_` property (added in the previous section), deleting the stored events of it as well. + +*** + +## 3. Create Module Definition File + +Create the file `src/modules/my-event/index.ts` with the following content: + +```ts title="src/modules/my-event/index.ts" +import MyEventService from "./service" +import { Module } from "@medusajs/framework/utils" + +export default Module("my-event", { + service: MyEventService, +}) +``` + +This exports the module's definition, indicating that the `MyEventService` is the main service of the module. + +*** + +## 4. Use Module + +To use your Event Module, add it to the `modules` object exported as part of the configurations in `medusa-config.ts`. An Event Module is added under the `eventBus` key. + +For example: + +```ts title="medusa-config.ts" +import { Modules } from "@medusajs/framework/utils" + +// ... + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/my-event", + options: { + // any options + }, + }, + ], +}) +``` + + +# File Module + +In this document, you'll learn about the File Module and its providers. + +## What is the File Module? + +The File Module exposes the functionalities to upload assets, such as product images, to the Medusa application. Medusa uses the File Module in its core commerce features for all file operations, and you can use it in your custom features as well. + +*** + +## How to Use the File Module? + +You can use the File Module as part of the [workflows](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) you build for your custom features. A workflow is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism. + +In a step of your workflow, you can resolve the File Module's service and use its methods to upload files, retrieve files, or delete files. + +For example: + +```ts +import { Modules } from "@medusajs/framework/utils" +import { + createStep, + createWorkflow, + StepResponse, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" + +const step1 = createStep( + "step-1", + async ({}, { container }) => { + const fileModuleService = container.resolve( + Modules.FILE + ) + + const { url } = await fileModuleService.retrieveFile("image.png") + + return new StepResponse(url) + } +) + +export const workflow = createWorkflow( + "workflow-1", + () => { + const url = step1() + + return new WorkflowResponse(url) + } +) +``` + +In the example above, you create a workflow that has a step. In the step, you resolve the service of the File Module from the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). + +Then, you use the `retrieveFile` method of the File Module to retrieve the URL of the file with the name `"image.png"`. The URL is then returned as a response from the step and the workflow. + +*** + +### What is a File Module Provider? + +A File Module Provider implements the underlying logic of handling uploads and downloads of assets, such as integrating third-party services. The File Module then uses the registered File Module Provider to handle file operations. + +Only one File Module Provider can be registered at a time. If you register multiple providers, the File Module will throw an error. + +By default, Medusa uses the [Local File Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/file/local/index.html.md). This module uploads files to the `uploads` directory of your Medusa application. + +This is useful for development.

Create Module Definition File - -Create the file `src/modules/my-event/index.ts` with the following content: - -```ts title="src/modules/my-event/index.ts" -import MyEventService from "./service" -import { Module } from "@medusajs/framework/utils" - -export default Module("my-event", { - service: MyEventService, -}) -``` - -This exports the module's definition, indicating that the `MyEventService` is the main service of the module. - -*** - -## 4. Use Module - -To use your Event Module, add it to the `modules` object exported as part of the configurations in `medusa-config.ts`. An Event Module is added under the `eventBus` key. - -For example: - -```ts title="medusa-config.ts" -import { Modules } from "@medusajs/framework/utils" - -// ... - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/my-event", - options: { - // any options - }, - }, - ], -}) -``` - - -# Local Event Module - -The Local Event Module uses Node EventEmitter to implement Medusa's pub/sub events system. The Node EventEmitter is limited to a single process environment. - -This module is useful for development and testing, but it’s not recommended to be used in production. - -For production, it’s recommended to use modules like [Redis Event Bus Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/event/redis/index.html.md). - -*** - -## Register the Local Event Module - -The Local Event Module is registered by default in your application. - -Add the module into the `modules` property of the exported object in `medusa-config.ts`: - -```ts title="medusa-config.ts" -import { Modules } from "@medusajs/framework/utils" - -// ... - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/event-bus-local", - }, - ], -}) -``` - -*** - -## Test the Module - -To test the module, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -You'll see the following message in the terminal's logs: - -```bash noCopy noReport -Local Event Bus installed.

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).

Then, you can use that provider to authenticate users using custom logic. + +In this step, you'll create a Phone Authentication Module Provider that allows users to log in with their phone numbers and an OTP. Later, you'll integrate Twilio to send the OTPs to the users, and customize the storefront to allow customers to log in with their phone numbers. + +An Authentication Module Provider doesn't need to handle storing and managing specific user details, such as creating customers or admin users. Instead, it only focuses on the logic of authenticating a type of user using custom logic or integration. You can learn more in the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) documentation. + +### Prerequisite: Install jsonwebtoken + +In the Phone Authentication Module Provider, you'll use the `jsonwebtoken` package to sign and verify the OTPs. + +To install the package, run the following command in the Medusa application directory: + +```bash npm2yarn +npm install jsonwebtoken +npm install @types/jsonwebtoken --save-dev +``` + +### a. Create Module Directory + +Modules are created under the `src/modules` directory. So, start by creating the directory `src/modules/phone-auth`. + +### b. Create Auth Module Provider Service + +A module has a service that contains its logic. For Authentication Module Providers, the service implements the logic to authenticate users. + +To create the service of the Phone Authentication Module Provider, create the file `src/modules/phone-auth/service.ts` with the following content: + +```ts title="src/modules/phone-auth/service.ts" highlights={phoneAuthServiceHighlights} +import { + AbstractAuthModuleProvider, + AbstractEventBusModuleService, +} from "@medusajs/framework/utils" +import { + Logger, +} from "@medusajs/types" + +type InjectedDependencies = { + logger: Logger + event_bus: AbstractEventBusModuleService +} + +type Options = { + jwtSecret: string +} + +class PhoneAuthService extends AbstractAuthModuleProvider { + static DISPLAY_NAME = "Phone Auth" + static identifier = "phone-auth" + private options: Options + private logger: Logger + private event_bus: AbstractEventBusModuleService + + constructor(container: InjectedDependencies, options: Options) { + // @ts-ignore + super(...arguments) + + this.options = options + this.logger = container.logger + this.event_bus = container.event_bus + } +} + +export default PhoneAuthService +``` + +An Authentication Module Provider's service must extend the `AbstractAuthModuleProvider` class. You'll get a type error about implementing the abstract methods of that class, which you'll add in the next steps. + +An Authentication Module Provider must also have the following static properties: + +- `identifier`: A unique identifier for the provider. +- `DISPLAY_NAME`: A human-readable name for the provider. This name is used for display purposes. + +A module provider's constructor receives two parameters: + +- `container`: The [module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md) that contains Framework resources available to the module. You access the following resources: + - `logger`: A [Logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) class to log debug messages. + - `event_bus`: The [Event Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/event/index.html.md)'s service to emit events. +- `options`: Options that are passed to the module provider when it's registered in Medusa's configurations. You define the following option: + - `jwtSecret`: A secret used to sign and verify the OTPs. + +You'll learn how to set this option when you [add the module provider to Medusa's configurations](#h-add-module-provider-to-medusas-configurations). + +In the constructor, you set the class's properties to the injected dependencies and options. + +In the next sections, you'll implement the methods of the `AbstractAuthModuleProvider` class. + +Refer to the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider/index.html.md) guide for detailed information about the methods. + +### c. Implement validateOptions Method + +The `validateOptions` method is used to validate the options passed to the module provider. If the method throws an error, the Medusa application won't start. + +So, add the `validateOptions` method to the `PhoneAuthService` class: + +```ts title="src/modules/phone-auth/service.ts" +// other imports... +import { + MedusaError, +} from "@medusajs/framework/utils" + +class PhoneAuthService extends AbstractAuthModuleProvider { + // ... + static validateOptions(options: Record): void | never { + if (!options.jwtSecret) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "JWT secret is required" + ) + } + } +} +``` + +The `validateOptions` method receives the options passed to the module provider as a parameter. + +In the method, you throw an error if the `jwtSecret` option is not set. + +### d. Implement register Method + +When a customer (or another actor type) registers in your application, they must also have an [auth identity](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-identity-and-actor-types/index.html.md) that allows them to login. + +The `register` method of an auth provider uses custom logic to create the auth identity for the actor type (such as customer). In the method, you can perform custom validation and specify the custom authentication details to store for the user's auth identity. + +Medusa uses the `register` method to create an auth identity that will be associated with the customer when they register. You can learn more in the [Authentication Flows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-flows/index.html.md) documentation. + +![Diagram showcasing the relation between a customer and auth identity](https://res.cloudinary.com/dza7lstvk/image/upload/v1747747179/Medusa%20Resources/customer-auth-identity_je1bvh.jpg) + +So, add the `register` method to the `PhoneAuthService` class: + +```ts title="src/modules/phone-auth/service.ts" highlights={registerHighlights} +// other imports... +import { + AuthenticationInput, + AuthIdentityProviderService, + AuthenticationResponse, +} from "@medusajs/types" + +class PhoneAuthService extends AbstractAuthModuleProvider { + // ... + async register( + data: AuthenticationInput, + authIdentityProviderService: AuthIdentityProviderService + ): Promise { + const { phone } = data.body || {} + + if (!phone) { + return { + success: false, + error: "Phone number is required", + } + } + + try { + await authIdentityProviderService.retrieve({ + entity_id: phone, + }) + + return { + success: false, + error: "User with phone number already exists", + } + } catch (error) { + const user = await authIdentityProviderService.create({ + entity_id: phone, + }) + + return { + success: true, + authIdentity: user, + } + } + } +} +``` + +#### Parameters + +The `register` method receives an object parameter with the following properties: + +- `data`: An object containing properties like `body` that holds request-body parameters. Clients will pass relevant authentication data, such as the user's phone number, in the request body. +- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. + +The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#register/index.html.md) guide. + +#### Method Logic + +In the method, you extract the `phone` property from the request body, and return an error if it's not provided. You also return an error if another user is using the same phone number. + +Otherwise, you create a new auth identity for the user. You set the phone number as the `entity_id` of the auth identity, which is a unique identifier. + +#### Return Value + +Finally, you return an object with the following properties: + +- `success`: A boolean indicating whether the registration was successful. +- `authIdentity`: The created auth identity of the user. This property is only set if the registration was successful. +- `error`: An error message if the registration failed. + +### e. Implement authenticate Method + +When a customer (or another actor type) logs in, the `authenticate` method of an auth provider is called. This method uses custom logic to authenticate the user. + +Authentication providers may implement one of the following flows: + +- Direct authentication, where the user is authenticated using this method only. For example, authenticating with an email and password. +- Authentication with callback verification, where the user is authenticated using this method and then a callback is used to verify additional information. + +For the Phone Authentication Module Provider, you'll implement the second flow. The user will first be authenticated using the `authenticate` method to make sure the user exists and generate an OTP. Then, they need to supply the OTP to verify their identity. + +![Diagram showcasing authentication with callback verification](https://res.cloudinary.com/dza7lstvk/image/upload/v1747749683/Medusa%20Resources/authentication-flow_ey59hw.jpg) + +So, add the `authenticate` method to the `PhoneAuthService` class: + +```ts title="src/modules/phone-auth/service.ts" highlights={authenticateHighlights} +// other imports... +import { + AuthIdentityDTO, +} from "@medusajs/types" +import jwt from "jsonwebtoken" + +class PhoneAuthService extends AbstractAuthModuleProvider { + // ... + async authenticate( + data: AuthenticationInput, + authIdentityProviderService: AuthIdentityProviderService + ): Promise { + const { phone } = data.body || {} + + if (!phone) { + return { + success: false, + error: "Phone number is required", + } + } + + try { + await authIdentityProviderService.retrieve({ + entity_id: phone, + }) + } catch (error) { + return { + success: false, + error: "User with phone number does not exist", + } + } + + const { hashedOTP, otp } = await this.generateOTP() + + await authIdentityProviderService.update(phone, { + provider_metadata: { + otp: hashedOTP, + }, + }) + + await this.event_bus.emit({ + name: "phone-auth.otp.generated", + data: { + otp, + phone, + }, + }, {}) + + return { + success: true, + location: "otp", + } + } + + async generateOTP(): Promise<{ hashedOTP: string, otp: string }> { + // Generate a 6-digit OTP + const otp = Math.floor(100000 + Math.random() * 900000).toString() + + // for debug + this.logger.info(`Generated OTP: ${otp}`) + + const hashedOTP = jwt.sign({ otp }, this.options.jwtSecret, { + expiresIn: "60s", + }) + + return { hashedOTP, otp } + } +} +``` + +You add two methods: the `authenticate` method, and a helper `generateOTP` method. + +#### authenticate Parameters + +The `authenticate` method receives an object parameter with the following properties: + +- `data`: An object containing properties like `body` that holds request-body parameters. Clients will pass relevant authentication data, such as the user's phone number, in the request body. +- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. + +The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#authenticate/index.html.md) guide. + +#### authenticate Logic + +In the method, you return an error if the `phone` property is not provided in the request body, or if a user with that phone number doesn't exist. + +Next, you generate a 6-digit OTP using the `generateOTP` method. Notice that you currently log the OTP for debugging purposes. You can remove this line later once you integrate Twilio. + +The OTP is hashed and stored in the `provider_metadata` property of the user's auth identity. The `provider_metadata` property is a JSON object that stores additional information about the auth identity. + +Then, you emit an event with the generated OTP and the user's phone number. This allows you later to handle the event and send the OTP to the user using services like Twilio. + +#### authenticate Return Value + +Finally, you return an object with the following properties: + +- `success`: A boolean indicating whether the authentication was successful. +- `location`: A string indicating a URL to perform additional actions in. In this case, you set the location to `otp`, indicating that the user should verify with the OTP. +- `error`: An error message if the authentication failed. + +### f. Implement validateCallback Method + +When an authentication provider requires a callback to verify the user, the Medusa application calls the `validateCallback` method. + +You can use this method to verify the OTP that the user entered. If valid, you return the logged in user, and the Medusa application will return a JWT token that the user can use to authenticate in the application. + +![Diagram showcasing how callback verification fits in the authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1747749734/Medusa%20Resources/callback-flow_yney5a.jpg) + +So, add the `validateCallback` method to the `PhoneAuthService` class: + +```ts title="src/modules/phone-auth/service.ts" highlights={validateCallbackHighlights} +class PhoneAuthService extends AbstractAuthModuleProvider { + // ... + async validateCallback( + data: AuthenticationInput, + authIdentityProviderService: AuthIdentityProviderService + ): Promise { + const { phone, otp } = data.query || {} + + if (!phone || !otp) { + return { + success: false, + error: "Phone number and OTP are required", + } + } + + const user = await authIdentityProviderService.retrieve({ + entity_id: phone, + }) + + if (!user) { + return { + success: false, + error: "User with phone number does not exist", + } + } + + // verify that OTP is correct + const userProvider = user.provider_identities?.find((provider) => provider.provider === this.identifier) + if (!userProvider || !userProvider.provider_metadata?.otp) { + return { + success: false, + error: "User with phone number does not have a phone auth provider", + } + } + + try { + const decodedOTP = jwt.verify( + userProvider.provider_metadata.otp as string, + this.options.jwtSecret + ) as { otp: string } + + if (decodedOTP.otp !== otp) { + throw new Error("Invalid OTP") + } + } catch (error) { + return { + success: false, + error: error.message || "Invalid OTP", + } + } + + const updatedUser = await authIdentityProviderService.update(phone, { + provider_metadata: { + otp: null, + }, + }) + + return { + success: true, + authIdentity: updatedUser, + } + } +} +``` + +#### Parameters + +The `validateCallback` method receives an object parameter with the following properties: + +- `data`: An object containing properties like `query` that holds query parameters. Clients will pass relevant authentication data, such as the user's phone number and OTP, in the request query. +- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. + +The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#validatecallback/index.html.md) guide. + +#### Method Logic + +In the method, you return an error if the phone and otp aren't provided in the request query, or if a user with that phone number doesn't exist. + +Next, you verify that the OTP provided by the user is correct. You retrieve the hashed OTP from the `provider_metadata` property of the user's auth identity. If the OTP is not valid, you return an error. + +Since you set the hash expiration to 60 seconds, the OTP will be valid for 60 seconds. After that, the user will need to request a new OTP. + +After that, you update the user's auth identity to remove the OTP from the `provider_metadata` property. + +#### Return Value + +Finally, you return an object with the following properties: + +- `success`: A boolean indicating whether the authentication was successful. +- `authIdentity`: The user's auth identity. This property is only set if the authentication was successful. +- `error`: An error message if the authentication failed. + +### g. Export Module Definition + +You've now finished implementing the necessary methods for the Phone Authentication Module Provider. + +The final piece to a module is its definition, which you export in an `index.ts` file at the module's root directory. This definition tells Medusa the name of the module, its service, and optionally its loaders. + +To create the module's definition, create the file `src/modules/phone-auth/index.ts` with the following content: + +```ts title="src/modules/phone-auth/index.ts" +import PhoneAuthService from "./service" +import { + ModuleProvider, + Modules, +} from "@medusajs/framework/utils" + +export default ModuleProvider(Modules.AUTH, { + services: [PhoneAuthService], +}) +``` + +You use `ModuleProvider` from the Modules SDK to create the module provider's definition. It accepts two parameters: + +1. The name of the module that this provider belongs to, which is `Modules.AUTH` in this case. +2. An object with a required property `services` indicating the module provider's services. Each of these services will be registered as authentication providers in Medusa. + +### h. Add Module Provider 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: + +```ts title="medusa-config.ts" +// other imports... +import { Modules, ContainerRegistrationKeys } from "@medusajs/framework/utils" + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/auth", + dependencies: [ + Modules.CACHE, + ContainerRegistrationKeys.LOGGER, + Modules.EVENT_BUS, + ], + options: { + providers: [ + // default provider + { + resolve: "@medusajs/medusa/auth-emailpass", + id: "emailpass", + }, + { + resolve: "./src/modules/phone-auth", + id: "phone-auth", + options: { + jwtSecret: process.env.PHONE_AUTH_JWT_SECRET || "supersecret", + }, + }, + ], + }, + }, + ], +}) +``` + +To pass an Auth Module Provider to the Auth Module, you add the `modules` property to the Medusa configuration and pass the Auth Module in its value. + +The Auth Module accepts a `dependencies` option, allowing you to inject dependencies into the containers of the module and its providers. The Auth Module requires passing the [Cache Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/cache/index.html.md) and Logger, but you also inject the `event_bus` dependency to use the Event Module's service in the Phone Authentication Module Provider. + +The Auth Module also accepts a `providers` option, which is an array of Auth Module Providers to register. You register the `emailpass` provider, which is registered by default when you don't provide any other providers. + +To register the Phone Authentication Module Provider, you add an object to the `providers` array with the following properties: + +- `resolve`: The NPM package or path to the module provider. In this case, it's the path to the `src/modules/phone-auth` directory. +- `id`: The ID of the module provider. The auth provider is then registered with the ID `au_{id}`. +- `options`: The options to pass to the module provider. These are the options you defined in the `Options` interface of the module provider's service. + +### i. Enable Phone Authentication for Customers + +By default, customers and admin users can be authenticated using the `emailpass` provider. When you add a new provider, you need to specify which actor types can use it. + +In `medusa-config.ts`, add to `projectConfig.http` a new `authMethodsPerActor` property: + +```ts title="medusa-config.ts" highlights={authMethodsPerActorHighlights} +module.exports = defineConfig({ + projectConfig: { + // ... + http: { + // ... + authMethodsPerActor: { + user: ["emailpass"], + customer: ["emailpass", "phone-auth"], + }, + }, + }, + // ... +}) +``` + +The `authMethodsPerActor` property is an object whose keys are actor types. The values are arrays of authentication method IDs that can be used for that actor type. + +In this case, you enable the `phone-auth` provider for customers. You can also enable it for other actor types, such as admin users or vendors. + +### Test Out Phone Authentication + +In this section, you'll test out the Phone Authentication Module Provider using Medusa's API routes. You can, instead, test it out later using the [Next.js Starter Storefront](#step-4-use-phone-authentication-in-the-nextjs-starter-storefront). + +First, start the Medusa application with the following command: + +```bash npm2yarn +npm run start +``` + +#### Prerequisite: Retrieve Publishable API Key + +Before you start testing the authentication provider using the API routes, you need to retrieve your application's publishable API key. This key is necessary to send requests to API routes starting with `/store`. + +To retrieve the publishable API key: + +1. Open the Medusa Admin dashboard at `http://localhost:9000/admin` and log in. +2. Go to Settings -> Publishable API Keys. +3. Click on the API key in the table. +4. In its details page, click on the API key to copy it. + +![Publishable API Key page with the API key clicked](https://res.cloudinary.com/dza7lstvk/image/upload/fl_lossy/f_auto/r_16/ar_16:9,c_pad/v1/User%20Guide/Screenshot_2025-02-25_at_6.14.15_PM_muwq9e.png) + +#### a. Retrieve Registration Token + +The first step is to retrieve a registration token for a new customer. This token will allow them to register in the application. + +To retrieve the registration token, send a `POST` request to `/auth/customer/phone-auth/register`: + +```bash +curl -X POST 'http://localhost:9000/auth/customer/phone-auth/register' \ +--header 'Content-Type: application/json' \ +--data '{ + "phone": "+19077890116" +}' +``` + +Make sure to replace the phone number with the one you want to use. + +This will return a `token` in the response: + +```json title="Example Response" +{ + "token": "123..." +} +``` + +#### b. Register Customer + +Next, you'll register the customer using the [Register Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You'll pass the registration token you received in the previous step in the header of this request. + +So, send a `POST` request to `/store/customers`: + +```bash +curl -X POST 'http://localhost:9000/store/customers' \ +--header 'x-publishable-api-key: {publishable_api_key}' \ +--header 'Content-Type: application/json' \ +--header 'Authorization: Bearer {reg_token}' \ +--data-raw '{ + "email": "+19077890116@gmail.com", + "phone": "19077890116", + "first_name": "John", + "last_name": "Smith" +}' +``` + +Make sure to replace: + +- `{publishable_api_key}` with the publishable API key you retrieved from the Medusa Admin dashboard. +- `{reg_token}` with the registration token you received in the previous step. +- The customer details in the request body with the ones you want to use. Use the same phone number you used in the previous step. + - You pass the email because it's required by the [Register Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You set it to the phone number with a `gmail.com` domain. + +The request will return the created customer's details: + +```json title="Example Response" +{ + "customer": { + "id": "cus_01JVPESW5SM1MSVPNM2MSC0ZEC", + "email": "+19077890116@gmail.com", + "company_name": null, + "first_name": "John", + "last_name": "Smith", + "phone": "19077890116", + "metadata": null, + "has_account": true, + "deleted_at": null, + "created_at": "2025-05-20T09:01:13.273Z", + "updated_at": "2025-05-20T09:01:13.273Z", + "addresses": [] + } +} +``` + +The customer can now authenticate using the phone number and OTP. + +#### c. Authenticate Customer + +Next, you'll authenticate the customer using the [Authenticate Customer](https://docs.medusajs.com/api/store#auth_postactor_typeauth_provider) API route. This would send the customer an OTP to their phone number (which you'll implement in the next step). + +So, send a `POST` request to `/auth/customer/phone-auth`: + +```bash +curl -X POST 'http://localhost:9000/auth/customer/phone-auth' \ +--header 'Content-Type: application/json' \ +--data '{ + "phone": "+19077890116" +}' +``` + +Make sure to replace the phone number with the one you used to register the customer. + +This will return a `location` in the response: + +```json title="Example Response" +{ + "location": "otp" +} +``` + +Indicating that the user should verify their OTP. + +You can also use this route to resend the OTP if the user didn't receive it or if a minute has passed since the last OTP was sent. + +#### d. Verify OTP + +If you check the logs of the Medusa application, you'll see that the OTP was generated and logged: + +```bash +info: Generated OTP: 576794 +``` + +As mentioned before, this is only for debugging purposes. In the next step, you'll implement the logic to send the OTP to the user using Twilio. + +So, to verify the OTP, you'll send a request to the [Verify Callback API route](https://docs.medusajs.com/api/store#auth_postactor_typeauth_providercallback): + +```bash +curl -X POST 'http://localhost:9000/auth/customer/phone-auth/callback?phone=%2B19077890116&otp=476588' +``` + +You pass the following query parameters: + +- `phone`: The phone number of the customer. Make sure to use the same phone number you used to register the customer, and to encode it. For example, the `+` sign should be encoded as `%2B`. +- `otp`: The OTP that the customer received. Make sure to use the same OTP shown in the logs. + +If the OTP is valid, you'll receive a JWT token in the response: + +```json title="Example Response" +{ + "token": "123..." +} +``` + +You can use this token to authenticate the customer in the application. For example, you can use the token to [retrieve the customer's details](https://docs.medusajs.com/api/store#customers_getcustomersme). + +If the OTP has expired, send a request to the [Authenticate Customer](#c-authenticate-customer) API route to generate a new OTP + +*** + +## Step 3: Integrate Twilio SMS + +Similar to the Auth Module, the [Notification Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/notification/index.html.md) allows registering custom providers to send notifications, such as SMS or email. + +In this step, you'll create a Twilio Notification Module Provider, then use it to send the OTP to the customer. + +### Prerequisites + +- [Twilio Account](https://console.twilio.com/) +- [Twilio From Phone Number](https://www.twilio.com/docs/phone-numbers) +- [Twilio Account SID, which you can retrieve from the Twilio Console homepage.](https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account-namer#console-dashboard-home-page) +- [Twilio Auth Token, which you can retrieve from the Twilio Console homepage.](https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account-namer#console-dashboard-home-page) + +### a. Install Twilio SDK + +Before you start implementing the Twilio Notification Module Provider, install the Twilio SDK to interact with the Twilio API. + +Run the following command in the Medusa application directory: + +```bash npm2yarn +npm install twilio +``` + +You'll use the Twilio SDK in the Notification Module Provider's service. + +### b. Create Module Directory + +Create the directory `src/modules/twilio-sms` to create the Twilio Notification Module Provider. + +### c. Create Notification Module Provider Service + +A Notification Module Provider has a service that contains the sending logic. The service must extend the `AbstractNotificationProviderService` class. + +So, create the file `src/modules/twilio-sms/service.ts` with the following content: + +```ts title="src/modules/twilio-sms/service.ts" highlights={twilioSmsServiceHighlights} +import { + AbstractNotificationProviderService, +} from "@medusajs/framework/utils" +import { Twilio } from "twilio" + +type InjectedDependencies = {} + +type TwilioSmsServiceOptions = { + accountSid: string + authToken: string + from: string +} + +class TwilioSmsService extends AbstractNotificationProviderService { + static readonly identifier = "twilio-sms" + private readonly client: Twilio + private readonly from: string + + constructor(container: InjectedDependencies, options: TwilioSmsServiceOptions) { + super() + + this.client = new Twilio(options.accountSid, options.authToken) + this.from = options.from + } +} +``` + +You'll get a type error about implementing the abstract methods of the `AbstractNotificationProviderService` class, which you'll add in the next steps. + +A Notification Module Provider must have an `identifier` static property, which is a unique identifier for the module. This identifier is used to register the module in the Medusa application. + +A module provider's constructor receives two parameters: + +- `container`: The [module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md) that contains Framework resources available to the module. You don't need to access any resources for this provider. +- `options`: Options that are passed to the module provider when it's registered in Medusa's configurations. You define the following option: + - `accountSid`: The Twilio account SID. + - `authToken`: The Twilio auth token. + - `from`: The Twilio phone number to send the SMS from. + +You'll learn how to set these options when you [add the module provider to Medusa's configurations](#g-add-module-provider-to-medusas-configurations). + +In the constructor, you set the class's properties to the injected dependencies and options. + +In the next sections, you'll implement the methods of the `AbstractNotificationProviderService` class. + +Refer to the [Create Notification Module Provider](https://docs.medusajs.com/references/notification-provider-module/index.html.md) guide for detailed information about the methods. + +### d. Implement validateOptions Method + +The `validateOptions` method is used to validate the options passed to the module provider. If the method throws an error, the Medusa application won't start. + +So, add the `validateOptions` method to the `TwilioSmsService` class: + +```ts title="src/modules/twilio-sms/service.ts" +class TwilioSmsService extends AbstractNotificationProviderService { + // ... + static validateOptions(options: Record): void | never { + if (!options.accountSid) { + throw new Error("Account SID is required") + } + if (!options.authToken) { + throw new Error("Auth token is required") + } + if (!options.from) { + throw new Error("From is required") + } + } +} +``` + +The `validateOptions` method receives the options passed to the module provider as a parameter. + +In the method, you throw an error if any of the options are not set. + +### e. Implement send Method + +The only required method for a Notification Module Provider is the `send` method. When the Medusa application needs to send a notification using the provider's channel (such as SMS), it calls this method of the registered provider. + +So, add the `send` method to the `TwilioSmsService` class: + +```ts title="src/modules/twilio-sms/service.ts" highlights={sendHighlights} +// other imports... +import { + ProviderSendNotificationDTO, + ProviderSendNotificationResultsDTO, +} from "@medusajs/types" + +class TwilioSmsService extends AbstractNotificationProviderService { + // ... + async send( + notification: ProviderSendNotificationDTO + ): Promise { + const { to, content, template, data } = notification + const contentText = content?.text || await this.getTemplateContent( + template, data + ) + + const message = await this.client.messages.create({ + body: contentText, + from: this.from, + to, + }) + + return { + id: message.sid, + } + } + + async getTemplateContent( + template: string, + data?: Record | null + ): Promise { + switch (template) { + case "otp-template": + if (!data?.otp) { + throw new Error("OTP is required for OTP template") + } + + return `Your OTP is ${data.otp}` + default: + throw new Error(`Template ${template} not found`) + } + } +} +``` + +You implement the `send` method and a helper `getTemplateContent` method. + +#### send Parameters + +The `send` method receives an object parameter with the following properties: + +- `to`: The phone number to send the SMS to. +- `content`: An object containing the content of the SMS. The `text` property is the text to send. +- `template`: The template to use for the SMS. This is used to retrieve the fallback content of the SMS if `content.text` is not provided. +- `data`: An object containing the data to use in the template. This is used to replace placeholders in the template with actual values. + +The method receives other parameters, which you can find in the [Create Notification Module Provider](https://docs.medusajs.com/references/notification-provider-module#send/index.html.md) guide. + +#### send Method Logic + +In the method, you set the SMS content either to the `text` property of the `content` object or to the template content. You define a `getTemplateContent` method that retrieves the content for a template. + +Then, you use the `messages.create` method of the Twilio client to send the SMS. You pass the following parameters: + +- `body`: The content of the SMS. +- `from`: The Twilio phone number to send the SMS from. +- `to`: The phone number to send the SMS to. + +#### send Return Value + +Finally, you return an object that has an `id` property with the ID of the sent SMS. This ID is stored in the notification record in the database. + +### f. Export Module Definition + +You've now finished implementing the necessary methods for the Twilio Notification Module Provider. You only need to export its definition. + +To create the module's definition, create the file `src/modules/twilio-sms/index.ts` with the following content: + +```ts title="src/modules/twilio-sms/index.ts" +import { + ModuleProvider, + Modules, +} from "@medusajs/framework/utils" +import TwilioSMSNotificationService from "./service" + +export default ModuleProvider(Modules.NOTIFICATION, { + services: [TwilioSMSNotificationService], +}) +``` + +You use `ModuleProvider` from the Modules SDK to create the module provider's definition passing it two parameters: + +1. The name of the module that this provider belongs to, which is `Modules.NOTIFICATION` in this case. +2. An object with a required property `services` indicating the module provider's services. Each of these services will be registered as notification providers in Medusa. + +### g. Add Module Provider to Medusa's Configurations + +You'll now add the Twilio Notification Module Provider to Medusa's configurations to start using it. + +In `medusa-config.ts`, add the following to the `modules` property: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + // ... + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + // default provider + { + resolve: "@medusajs/medusa/notification-local", + id: "local", + options: { + name: "Local Notification Provider", + channels: ["feed"], + }, + }, + { + resolve: "./src/modules/twilio-sms", + id: "twilio-sms", + options: { + channels: ["sms"], + accountSid: process.env.TWILIO_ACCOUNT_SID, + authToken: process.env.TWILIO_AUTH_TOKEN, + from: process.env.TWILIO_FROM, + }, + }, + ], + }, + }, + ], +}) +``` + +You pass the Notification Module in the `modules` property to register the Twilio Notification Module Provider. + +The Notification Module accepts a `providers` option, which is an array of Notification Module Providers to register. You register the `local` provider, which is registered by default when you don't provide any other providers. + +To register the Twilio Notification Module Provider, you add an object with the following properties: + +- `resolve`: The path to the module provider. +- `id`: The ID of the module provider. The notification provider is then registered with the ID `np_{identifier}_{id}`. +- `options`: The options to pass to the module provider. These include the options you defined in the `Options` interface of the module provider's service. + - `channels`: The channels that the notification provider supports. In this case, you set it to `sms`, which is the channel used to send SMS notifications. + - `accountSid`: The Twilio account SID. + - `authToken`: The Twilio auth token. + - `from`: The Twilio phone number to send the SMS from. + +### h. Add Environment Variables + +To set the value of the Twilio options, add the following environment variables to your `.env` file: + +```shell title=".env" +TWILIO_ACCOUNT_SID=AC... +TWILIO_AUTH_TOKEN=05... +TWILIO_FROM=+1... +``` + +Where: + +- `TWILIO_ACCOUNT_SID`: The Twilio account SID. +- `TWILIO_AUTH_TOKEN`: The Twilio auth token. +- `TWILIO_FROM`: The Twilio phone number to send the SMS from. Make sure to use the phone number you purchased from Twilio. + +You can retrieve these information from the Twilio Console homepage. + +![Twilio console homepage showing the account SID, phone number, and auth token](https://res.cloudinary.com/dza7lstvk/image/upload/v1747736641/Medusa%20Resources/CleanShot_2025-05-20_at_13.22.55_2x_sztmfo.png) + +### i. Handle OTP Generated Event + +Now that you have integrated Twilio into Medusa, you can use it to send the OTP to the customer. To do that, you need to handle the `phone-auth.otp.generated` event that you emitted in the `authenticate` method of the Phone Authentication Module Provider. + +You can listen to events in a [subscriber](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that listens to events to perform actions when the event is emitted. + +In this step, you'll create a subscriber that listens to the `phone-auth.otp.generated` event and sends an SMS to the customer with the OTP. + +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 file `src/subscribers/send-otp.ts` with the following content: + +```ts title="src/subscribers/send-otp.ts" highlights={sendOtpHighlights} +import { + SubscriberArgs, + type SubscriberConfig, +} from "@medusajs/medusa" +import { Modules } from "@medusajs/framework/utils" + +export default async function sendOtpHandler({ + event: { data: { + phone, + otp, + } }, + container, +}: SubscriberArgs<{ phone: string, otp: string }>) { + const notificationModuleService = container.resolve( + Modules.NOTIFICATION + ) + + await notificationModuleService.createNotifications({ + to: phone, + channel: "sms", + template: "otp-template", + data: { + otp, + }, + }) +} + +export const config: SubscriberConfig = { + event: "phone-auth.otp.generated", +} +``` + +The subscriber file must export: + +- An asynchronous subscriber function that's executed whenever the associated event is triggered. +- A configuration object with an event property whose value is the event the subscriber is listening to, which is `phone-auth.otp.generated`. + +The subscriber function accepts an object with the following properties: + +- `event`: An object with the event's data payload. In the `authenticate` method, you emitted the event with the following data: + - `phone`: The phone number of the user. + - `otp`: The OTP that was generated. +- `container`: The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which you can use to resolve Framework and commerce resources. + +In the subscriber function, you resolve the Notification Module's service from the Medusa container. Then, you use its `createNotifications` method to send the OTP to the user. + +Under the hood, the Notification Module's service delegates the sending to the Notification Module Provider of the `sms` channel, which is the Twilio Notification Module Provider in this case. + +The `createNotifications` method accepts an object with the following properties: + +- `to`: The phone number to send the notification to. You use the phone number from the event's data payload. +- `channel`: The channel to use to send the notification, which is `sms`. +- `template`: The template to use for the notification content, which is `otp-template`. +- `data`: An object containing the data to use in the template. You pass the OTP to the template. + +### j. Test it Out + +To test out the Twilio Notification Module Provider, you can follow the steps in the [Test Out Phone Authentication](#test-out-phone-authentication) section. + +After you authenticate the customer, the OTP will be sent to the customer's phone number using Twilio. Then, you can use the OTP to verify the authentication and receive a JWT token. + +Alternatively, you can also test it out after customizing the Next.js Starter Storefront, which you'll do in the next step. + +Make sure to remove the OTP logging line in the `generateOTP` method of the Phone Authentication Module Provider's service now that you have integrated Twilio. + +*** + +## Step 4: Use Phone Authentication in the Next.js Starter Storefront + +In this step, you'll customize the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to allow customers to authenticate using their phone number and OTP. + +By default, the Next.js Starter Storefront supports email and password authentication. You'll replace it with phone authentication, but you can also keep both authentication methods if you want to. + +The Next.js Starter Storefront was installed in a separate directory from Medusa. The directory's name is `{your-project}-storefront`. + +So, if your Medusa application's directory is `medusa-phone-auth`, you can find the storefront by going back to the parent directory and changing to the `medusa-phone-auth-storefront` directory: + +```bash +cd ../medusa-phone-auth-storefront # change based on your project name +``` + +### a. Install Phone Input Package + +To easily show a phone input where the user can enter their phone number, install the `react-phone-number-input` package: + +```bash npm2yarn badgeLabel="Storefront" badgeColor="blue" +npm install react-phone-number-input +``` + +You'll use it in the login and registration forms to show a phone input. + +### b. Add Authenticate Function + +Before adding the forms, you'll add the functions that send requests to the Medusa API to authenticate the customer. + +The first one you'll add is the `authenticateWithPhone` function, which sends a request to the `/auth/customer/phone-auth` API route to authenticate the customer using their phone number. + +In `src/lib/data/customer.ts`, add the following function: + +```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" +export const authenticateWithPhone = async (phone: string) => { + try { + const response = await sdk.auth.login("customer", "phone-auth", { + phone, + }) + + if ( + typeof response === "string" || + !response.location || + response.location !== "otp" + ) { + throw new Error("Failed to login") + } + + return true + } catch (error: any) { + return error.toString() + } +} +``` + +The function accepts the phone number as a parameter. + +In the function, you use the [JS SDK](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md), which is configured within the Next.js Starter Storefront, to send a request to the `/auth/customer/phone-auth` API route. You pass the phone number in the request body. + +If the request doesn't return a `location` property set to `otp`, you throw an error. Otherwise, you return `true` to indicate that the request was successful. + +### c. add Verify OTP Function + +Next, you'll add the `verifyOTP` function, which sends a request to the `/auth/customer/phone-auth/callback` API route to verify the OTP. + +In `src/lib/data/customer.ts`, add the following function: + +```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" highlights={verifyOtpHighlights} +export const verifyOtp = async ({ + otp, + phone, +}: { + otp: string + phone: string +}) => { + try { + const token = await sdk.auth.callback("customer", "phone-auth", { + phone, + otp, + }) + + await setAuthToken(token) + + const customerCacheTag = await getCacheTag("customers") + revalidateTag(customerCacheTag) + + await transferCart() + + return true + } catch (e: any) { + return e.toString() + } +} +``` + +The function accepts an object with the following properties: + +- `otp`: The OTP to verify. +- `phone`: The phone number of the customer. + +In the function, you use the JS SDK to send a request to the `/auth/customer/phone-auth/callback` API route. You pass the phone number and OTP in the request body. + +If the request is successful and you receive a token, you set the token in the cookies and refresh the customer cache. This ensures that all customer-related UI is updated after logging in, such as showing the customer's profile when accessing the `/account` page. + +Then, you call the `transferCart` function to transfer the cart from the guest user to the authenticated customer. + +Finally, you return `true` to indicate that the request was successful. + +### d. Add Registration Function + +The last function you'll add is the `registerWithPhone` function, which will register the customer using their phone number. + +In `src/lib/data/customer.ts`, add the following function: + +```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" highlights={registerWithPhoneHighlights} +export const registerWithPhone = async ({ + firstName, + lastName, + phone, +}: { + firstName: string + lastName: string + phone: string +}) => { + try { + const { token: regToken } = await sdk.client.fetch< + { token: string } + >(`/auth/customer/phone-auth/register`, { + method: "POST", + body: { + phone, + }, + }) + + await setAuthToken(regToken as string) + const headers = { + ...(await getAuthHeaders()), + } + + const email = `${phone}@gmail.com` + const customerData = { + email, + first_name: firstName, + last_name: lastName, + phone, + } + + await sdk.store.customer.create( + customerData, + {}, + headers + ) + + return await authenticateWithPhone(phone) + } catch (error: any) { + return error.toString() + } +} +``` + +The function accepts an object with the following properties: + +- `firstName`: The first name of the customer. +- `lastName`: The last name of the customer. +- `phone`: The phone number of the customer. + +In the function, you retrieve a registration token for the customer using the `/auth/customer/phone-auth/register` API route. You pass the phone number in the request body. + +Then, after setting the registration token in the cookies, you create a customer using the [Create Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You pass the following properties in the request body: + +- `email`: The email of the customer. You set it to the phone number with a `@gmail.com` domain. +- `first_name`: The first name of the customer. +- `last_name`: The last name of the customer. +- `phone`: The phone number of the customer. + +Finally, you call the `authenticateWithPhone` function to authenticate the customer using their phone number. At this step, the customer would receive an OTP to login. + +### e. Add OTP Form + +Next, you'll add an OTP form that allows the customer to enter the OTP they receive after login or registration. Later, you'll reuse this form in both the login and registration pages. + +Create the file `src/modules/account/components/otp/index.tsx` with the following content: + +```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={otpHighlights} +"use client" + +import { Input } from "@medusajs/ui" +import { useState, useRef, useEffect } from "react" +import { authenticateWithPhone, verifyOtp } from "../../../../lib/data/customer" +import ErrorMessage from "../../../checkout/components/error-message" + +type Props = { + phone: string +} + +export const Otp = ({ phone }: Props) => { + const [otp, setOtp] = useState("") + const [error, setError] = useState("") + const [isLoading, setIsLoading] = useState(false) + const [countdown, setCountdown] = useState(60) + const inputRefs = useRef<(HTMLInputElement | null)[]>([]) + + const handleSubmit = async () => { + setIsLoading(true) + const response = await verifyOtp({ + otp, + phone, + }) + setOtp("") + setIsLoading(false) + + if (typeof response === "string") { + setError(response) + } + } + + const handleResend = async () => { + authenticateWithPhone(phone) + setCountdown(60) + } + + const handlePaste = (e: React.ClipboardEvent) => { + e.preventDefault() + const pastedData = e.clipboardData.getData("text") + const numericValue = pastedData.replace(/\D/g, "").slice(0, 6) + + if (numericValue) { + setOtp(numericValue) + // Focus the next empty input after pasted content + const nextEmptyIndex = Math.min(numericValue.length, 5) + inputRefs.current[nextEmptyIndex]?.focus() + } + } + + // TODO add use effects +} +``` + +You create an `Otp` component that accepts the phone number as a prop. + +In the component, you define the following state variables: + +- `otp`: The OTP entered by the customer. +- `error`: The error message to show if the OTP verification fails. +- `isLoading`: A boolean indicating whether the OTP verification is in progress. +- `countdown`: The countdown timer for resending the OTP. +- `inputRefs`: A ref to store the input elements for the OTP digits. You'll show six input elements for the OTP digits. + +You also define the following functions: + +- `handleSubmit`: This function is called when the customer submits the OTP. It calls the `verifyOtp` function to verify the OTP entered by the customer. +- `handleResend`: This function is called when the customer clicks the "Resend OTP" button that you'll add later. It calls the `authenticateWithPhone` function to resend the OTP to the customer's phone number. +- `handlePaste`: This function is called when the customer pastes the OTP in the input field. It improves the experience of pasting the OTP without having to enter it manually. + +#### Handle Variable Changes + +Next, you'll add `useEffect` hooks to handle changes in the state variables. + +Replace the `TODO` with the following: + +```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={useEffectHighlights} +useEffect(() => { + if (inputRefs.current[0]) { + inputRefs.current[0].focus() + } +}, [inputRefs.current]) + +useEffect(() => { + if (otp.length !== 6 || isLoading) { + return + } + + handleSubmit() +}, [otp, isLoading]) + +useEffect(() => { + const timer = setInterval(() => { + setCountdown((prev) => { + return prev > 0 ? prev - 1 : 0 + }) + }, 1000) + + return () => clearInterval(timer) +}, []) + +// TODO render form +``` + +You add three `useEffect` hooks: + +1. The first one focuses the first input element when the component mounts. +2. The second one automatically submits the OTP when the customer enters six digits. +3. The third one adds an interval to update the countdown timer every second. + +### f. Render OTP Form + +Lastly, you'll render the OTP form with the input elements and the resend button. + +Replace the `TODO` with the following: + +```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" +return ( +
+

+ Verify Phone Number +

+

+ Enter the code sent to your phone number to login. +

+
+ {[...Array(6)].map((_, index) => ( + { + inputRefs.current[index] = el + }} + onPaste={handlePaste} + value={otp[index] || ""} + onChange={(e) => { + const elm = e.target + const value = elm.value + setOtp((prev) => { + const newOtp = prev.split("") + newOtp[index] = value + return newOtp.join("") + }) + if (value && /^\d+$/.test(value)) { + // Move focus to next input + const nextInput = elm.parentElement?.nextElementSibling?.querySelector("input") + nextInput?.focus() + } + }} + onKeyDown={(e) => { + if (e.key === "Backspace" && !e.currentTarget.value) { + // Move focus to previous input on backspace + const prevInput = e.currentTarget.parentElement?.previousElementSibling?.querySelector("input") + prevInput?.focus() + } + }} + /> + ))} +
+
+ +
+ +
+) +``` + +You show six input elements for the OTP digits. When a value is entered in an input, the focus moves to the next input. In addition, when the customer presses backspace on an empty input, the focus moves to the previous input. + +You also show a resend button that allows the customer to resend the OTP once the countdown timer reaches zero. + +You now have an OTP form that you can use in both the login and registration pages. + +### g. Add Registration Form + +You'll now add a registration form that allows the customer to register using their phone number. + +First, in `src/modules/account/templates/login-template.tsx`, update the `LOGIN_VIEW` to the following: + +```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["4"], ["5"]]} +export enum LOGIN_VIEW { + SIGN_IN = "sign-in", + REGISTER = "register", + REGISTER_PHONE = "register-phone", + SIGN_IN_PHONE = "sign-in-phone", +} +``` + +By default, the login template supports switching between the login and registration views for email and password authentication. With the above change, you add two new views: login and registration with phone number. + +Then, to add the registration form, create the file `src/modules/account/components/register-phone/index.tsx` with the following content: + +```tsx title="src/modules/account/components/register-phone/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={registerPhoneHighlights} +"use client" + +import { useState } from "react" +import Input from "@modules/common/components/input" +import { LOGIN_VIEW } from "@modules/account/templates/login-template" +import ErrorMessage from "@modules/checkout/components/error-message" +import LocalizedClientLink from "@modules/common/components/localized-client-link" +import { registerWithPhone } from "@lib/data/customer" +import "react-phone-number-input/style.css" +import PhoneInput from "react-phone-number-input" +import { Otp } from "../otp" +import { useParams } from "next/navigation" +import { Button } from "@medusajs/ui" + +type Props = { + setCurrentView: (view: LOGIN_VIEW) => void +} + +const RegisterPhone = ({ setCurrentView }: Props) => { + const [firstName, setFirstName] = useState("") + const [lastName, setLastName] = useState("") + const [phone, setPhone] = useState("") + const [error, setError] = useState("") + const [loading, setLoading] = useState(false) + const [enterOtp, setEnterOtp] = useState(false) + const { countryCode } = useParams() as { countryCode: string } + + const handleSubmit = async (e: React.FormEvent) => { + e.preventDefault() + setLoading(true) + const response = await registerWithPhone({ + firstName, + lastName, + phone, + }) + setLoading(false) + if (typeof response === "string") { + setError(response) + return + } + + setEnterOtp(true) + } + + if (enterOtp) { + return + } + + // TODO render form +} + +export default RegisterPhone +``` + +You create a `RegisterPhone` component that accepts a `setCurrentView` prop to switch between the login and registration views. + +In the component, you define the following state variables: + +- `firstName`, `lastName`, and `phone` to store the form inputs' values. +- `error`: The error message to show if the registration fails. +- `loading`: A boolean indicating whether the registration is in progress. +- `enterOtp`: A boolean indicating whether to show the OTP form.

Add to Login Template + +Next, you'll add the `LoginPhone` component to the login template. + +In `src/modules/account/templates/login-template.tsx`, add the following import: + +```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" +import LoginPhone from "../components/login-phone" +``` + +Next, in the `LoginTemplate` component, change the default value of the `currentView` state to `LOGIN_VIEW.SIGN_IN_PHONE`: + +```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" +const [currentView, setCurrentView] = useState(LOGIN_VIEW.SIGN_IN_PHONE) +``` + +This ensures the phone login form is shown by default. + +Finally, replace the `return` statement of the `LoginTemplate` component to the following: + +```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" +return ( +

Show the phone number in the profile page: Currently, it shows the email address, which is a fake address you've set. +2. Disable phone and email updates: Currently, the customer can update their phone number, which is not allowed for phone authentication. + +### a. Show Phone Number in Profile Page + +To show the phone number in the profile page instead of the email, in `src/modules/account/components/overview/index.tsx`, find the following in the `return` statement: + +```tsx title="src/modules/account/components/overview/index.tsx" badgeLabel="Storefront" badgeColor="blue" + + {customer?.email} + +``` + +And replace it with the following: + +```tsx title="src/modules/account/components/overview/index.tsx" badgeLabel="Storefront" badgeColor="blue" + + {customer?.phone} + +``` + +If you check the profile page now, you'll see the phone number instead of the email address at the top right. + +![Phone number showing in profile page](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740378/Medusa%20Resources/CleanShot_2025-05-20_at_14.25.59_2x_x0pxvt.png) + +### b. Remove Email and Phone Fields + +Next, you'll remove the fields to update email and phone number from the profile page. + +In `src/app/[countryCode]/(main)/account/@dashboard/profile/page.tsx`, find the following lines to remove from the `return` statement: + +```tsx title="src/app/[countryCode]/(main)/account/@dashboard/profile/page.tsx" badgeLabel="Storefront" badgeColor="blue" +
+ {/* ... */} + {/* Remove the following */} + + + + + {/* ... */} +
+``` + +If you go to your profile page and click on "Profile" in the sidebar, the email and phone number sections will be removed. + +![Profile page without email and phone fields](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740515/Medusa%20Resources/CleanShot_2025-05-20_at_14.28.09_2x_ugab7d.png) + +### c. Disable Phone Updates in Medusa + +While removing the email and phone fields from the profile page prevents customers using the storefront from updating their phone number, it doesn't prevent them from updating it using Medusa's API. + +In this section, you'll add a [middleware](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) to the `/store/customers/me` API route that prevents customers from updating their phone number. + +A middleware is a function that's executed whenever a request is sent to an API route. It's executed before the route handler, allowing you to validate requests, apply authentication guards, and more. + +Learn more in the [Middlewares](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) documentation. + +To add a middleware in your Medusa application, create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" badgeLabel="Medusa Application" badgeColor="green" +import { defineMiddlewares } from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/customers/me", + method: ["POST"], + middlewares: [ + async (req, res, next) => { + const { phone } = req.body as Record + + if (phone) { + return res.status(400).json({ + error: "Phone number is not allowed to be updated", + }) + } + + next() + }, + ], + }, + ], +}) +``` + +You define middlewares using the `defineMiddlewares` function. It accepts an object having a `routes` property that holds all middlewares applied to API routes. + +Each object in `routes` has the following properties: + +- `matcher`: The API route path to apply the middleware on. You set it to `/store/customers/me`. +- `method`: The HTTP method to apply the middleware to. You set it to `POST` so that the middleware is applied only on `POST` requests sent to the `/store/customers/me` route. +- `middlewares`: An array of middlewares to apply on the route. You add a middleware that throws an error if the request body contains a `phone` property. This prevents customers from updating their phone number using the API. + +Any `POST` request to the `/store/customers/me` route will now be validated to ensure it's not updating the phone number. + +*** + +## Next Steps + +You've now implemented phone authentication in Medusa with Twilio integration. You can further customize the phone authentication feature based on your business use case. + +### Authenticate Other Actor Types + +This tutorial focused on authenticating customers using their phone number. However, you can also authenticate other actor types, such as admin users and vendors. + +To do that, first, enable the `phone-auth` authentication strategy in `medusa-config.ts` for the actor types. For example: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + projectConfig: { + // ... + http: { + // ... + authMethodsPerActor: { + user: ["emailpass", "phone-auth"], + customer: ["emailpass", "phone-auth"], + vendor: ["emailpass", "phone-auth"], + }, + }, + }, +}) +``` + +Then, when sending requests to the authentication API routes mentioned in the [Test Out Phone Authentication](#test-out-phone-authentication) section, replace `customer` in the API route paths with the actor type you want to authenticate: + +- `/auth/customer/phone-auth/register` -> `/auth/user/phone-auth/register` +- `/auth/customer/phone-auth` -> `/auth/user/phone-auth` +- `/auth/customer/phone-auth/callback` -> `/auth/user/phone-auth/callback` + +Finally, update the UI to show the phone authentication option for the actor type you want to authenticate. This depends on the UI you're using, but you can follow an approach similar to the Next.js Starter Storefront customizations. + +The login form of Medusa Admin can't be customized, so you'll have to build a custom admin dashboard to support phone authentication for admin users. + +### Learn More about Medusa + +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). + +### Troubleshooting + +If you encounter issues during your development, check out the [troubleshooting guides](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/troubleshooting/index.html.md). + +### Getting Help + +If you encounter issues not covered in the troubleshooting guides: + +1.

While the Payment Module is loaded by default, you need to add it again when registering a new provider. - -You register provides in the `providers` option of the Payment Module. Each provider is an object with the following properties: - -- `resolve`: The package name of the provider. -- `id`: The ID of the provider. This is used to identify the provider in the Medusa application. -- `options`: The options to be passed to the provider. In this case, the `apiKey` option is required for the Stripe Module Provider. - -Learn about other options in the [Stripe Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-provider/stripe#module-options/index.html.md) documentation. - -### Add Environment Variables - -Next, add the following environment variables to your `.env` file: - -```plain -STRIPE_API_KEY=sk_... -``` - -Where `STRIPE_API_KEY` is your Stripe Secret API Key. You can find it in the Stripe dashboard under Developers > API keys. - -![Secret API Key in the Stripe dashboard](https://res.cloudinary.com/dza7lstvk/image/upload/v1745313823/Medusa%20Resources/Screenshot_2025-04-22_at_12.20.08_PM_w6rxxo.png) - -### Enable Stripe in a Region - -In Medusa, each [region](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/region/index.html.md) (which is a geographical area where your store operates) can have different payment methods enabled. So, after registering the Stripe Module Provider, you need to enable it in a region. - -To enable it in a region, start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Then, go to `localhost:9000/app` and log in with the user you created earlier. - -Once you're logged in: - -1. Go to Settings -> Regions. -2. Click on the region where you want to enable the payment provider. -3. Click the icon at the top right of the first section -4. Choose "Edit" from the dropdown menu -5. In the side window that opens, find the "Payment Providers" field and select Stripe from the dropdown. -6.

The directory's name is `{your-project}-storefront`. - -So, if your Medusa application's directory is `medusa-payment`, you can find the storefront by going back to the parent directory and changing to the `medusa-payment-storefront` directory: - -```bash -cd ../medusa-payment-storefront # change based on your project name -``` - -In the Next.js Starter Storefront project, add the Stripe public API key as an environment variable in `.env.local`: - -```plain badgeLabel="Storefront" badgeColor="blue" -NEXT_PUBLIC_STRIPE_KEY=pk_123... -``` - -Where `NEXT_PUBLIC_STRIPE_KEY` is your Stripe public API key. You can find it in the Stripe dashboard under Developers > API keys. - -*** - -## Step 3: List Payment Methods API Route - -The Payment Module uses [account holders](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/account-holder/index.html.md) to represent a customer's details that are stored in a third-party payment provider. Medusa creates an account holder for each customer, allowing you later to retrieve the customer's saved payment methods in the third-party provider. - -![Diagram illustrating the relation between customers and account holders in Medusa, and customers in Stripe](https://res.cloudinary.com/dza7lstvk/image/upload/v1745314344/Medusa%20Resources/customer-account-stripe_in5ei6.jpg) - -While this feature is available out-of-the-box, you need to expose it to clients, like storefronts, by creating an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). An API Route is an endpoint that exposes commerce features to external applications and clients. - -In this step, you'll create an API route that lists the saved payment methods for an authenticated customer. - -Refer to the [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md) documentation to learn more. - -### Create API Route - -An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`, and it can include path parameters using square brackets. - -So, to create an API route at the path `/store/payment-methods/:account-holder-id`, create the file `src/api/store/payment-methods/[account_holder_id]/route.ts` with the following content: - -```ts title="src/api/store/payment-methods/[account_holder_id]/route.ts" highlights={apiRouteHighlights} -import { MedusaError } from "@medusajs/framework/utils" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export async function GET( - req: MedusaRequest, - res: MedusaResponse -) { - const { account_holder_id } = req.params - const query = req.scope.resolve("query") - const paymentModuleService = req.scope.resolve("payment") - - const { data: [accountHolder] } = await query.graph({ - entity: "account_holder", - fields: [ - "data", - "provider_id", - ], - filters: { - id: account_holder_id, - }, - }) - - if (!accountHolder) { - throw new MedusaError( - MedusaError.Types.NOT_FOUND, - "Account holder not found" - ) - } - - const paymentMethods = await paymentModuleService.listPaymentMethods( - { - provider_id: accountHolder.provider_id, - context: { - account_holder: { - data: { - id: accountHolder.data.id, - }, - }, - }, - } - ) - - res.json({ - payment_methods: paymentMethods, - }) -} -``` - -Since you export a route handler function named `GET`, you expose a `GET` API route at `/store/payment-methods/:account-holder-id`. The route handler function accepts two parameters: - -1. A request object with details and context on the request, such as body parameters or authenticated customer details. -2. A response object to manipulate and send the response. - -The request object has a `scope` property, which is an instance of the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). The Medusa container is a registry of Framework and commerce tools that you can access in the API route. - -You use the Medusa container to resolve: - -- [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules in the Medusa application. -- The [Payment Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/index.html.md)'s service, which provides an interface to manage and process payments with third-party providers. - -You use Query to retrieve the account holder with the ID passed as a path parameter. If the account holder is not found, you throw an error. - -Then, you use the [listPaymentMethods](https://docs.medusajs.com/references/payment/listPaymentMethods/index.html.md) method of the Payment Module's service to retrieve the payment providers saved in the third-party provider. The method accepts an object with the following properties: - -- `provider_id`: The ID of the provider, such as Stripe's ID. The account holder stores the ID its associated provider. -- `context`: The context of the request. In this case, you pass the account holder's ID to retrieve the payment methods associated with it in the third-party provider. - -Finally, you return the payment methods in the response. - -### Protect API Route - -Only authenticated customers can access and use saved payment methods. So, you need to protect the API route to ensure that only authenticated customers can access it. - -To protect an API route, you can add a [middleware](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). A middleware is a function executed when a request is sent to an API Route. You can add an authentication middleware that ensures that the request is authenticated before executing the route handler function. - -Refer to the [Middlewares](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) documentation to learn more. - -Middlewares are added in the `src/api/middlewares.ts` file. So, create the file with the following content: - -```ts title="src/api/middlewares.ts" -import { authenticate, defineMiddlewares } from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/payment-methods/:provider_id/:account_holder_id", - method: "GET", - middlewares: [ - authenticate("customer", ["bearer", "session"]), - ], - }, - ], -}) -``` - -The `src/api/middlewares.ts` file must use the `defineMiddlewares` function and export its result. The `defineMiddlewares` function accepts a `routes` array that accepts objects with the following properties: - -- `matcher`: The path of the API route to apply the middleware to. -- `method`: The HTTP method of the API route to apply the middleware to. -- `middlewares`: An array of middlewares to apply to the API route. - -You apply the `authenticate` middleware to the API route you created earlier. The `authenticate` middleware ensures that only authenticated customers can access the API route. - -Refer to the [Protected Routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/protected-routes/index.html.md) documentation to learn more about the `authenticate` middleware. - -Your API route can now only be accessed by authenticated customers. You'll test it out as you customize the Next.js Starter Storefront in the next steps. - -*** - -## Step 4: Save Payment Methods During Checkout - -In this step, you'll customize the checkout flow in the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to save payment methods during checkout. - -The Next.js Starter Storefront was installed in a separate directory from Medusa. The directory's name is `{your-project}-storefront`. - -So, if your Medusa application's directory is `medusa-payment`, you can find the storefront by going back to the parent directory and changing to the `medusa-payment-storefront` directory: - -```bash -cd ../medusa-payment-storefront # change based on your project name -``` - -During checkout, when the customer chooses a payment method, such as Stripe, the Next.js Starter Storefront creates a [payment session](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/payment/payment-session/index.html.md) in Medusa using the [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route. - -Under the hood, Medusa uses the associated payment provider (Stripe) to initiate the payment process with the associated third-party payment provider. The [Initialize Payment Session](https://docs.medusajs.com/api/store#payment-collections_postpaymentcollectionsidpaymentsessions) API route accepts a `data` object parameter in the request body that allows you to pass data relevant to the third-party payment provider. - -So, to save the payment method that the customer uses during checkout with Stripe, you must pass the `setup_future_usage` property in the `data` object. The `setup_future_usage` property is a Stripe-specific property that allows you to save the payment method for future use. - -In `src/modules/checkout/components/payment/index.tsx` of the Next.js Starter Storefront, there are two uses of the `initiatePaymentSession` function. Update each of them to pass the `data` property: - -```ts title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" -// update in two places -await initiatePaymentSession(cart, { - // ... - data: { - setup_future_usage: "off_session", - }, -}) -``` - -You customize the `initiatePaymentSession` function to pass the `data` object with the `setup_future_usage` property. You set the value to `off_session` to allow using the payment method outside of the checkout flow, such as for follow up payments. You can use `on_session` instead if you only want the payment method to be used by the customer during checkout. - -By making this change, you always save the payment method that the customer uses during checkout. You can alternatively show a checkbox to confirm saving the payment method, and only pass the `data` object if the customer checks it. - -### Test it Out - -To test it out, start the Medusa application by running the following command in the Medusa application's directory: - -```bash npm2yarn -npm run dev -``` - -Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: - -```bash npm2yarn -npm run dev -``` - -You can open the storefront in your browser at `localhost:8000`. Then, create a new customer account by clicking on the "Account" link at the top right. - -After creating an account and logging in, add a product to the cart and go to the checkout page. Once you get to the payment step, choose Stripe and enter a [test card number](https://docs.stripe.com/testing#cards), such as `4242 4242 4242 4242`. - -Then, place the order. Once the order is placed, you can check on the Stripe dashboard that the payment method was saved by: - -1. Going to the "Customers" section in the Stripe dashboard. -2. Clicking on the customer you just placed the order with. -3. Scrolling down to the "Payment methods" section. You'll find the payment method you just used to place the order. - -![Saved payment method on the Stripe dashboard](https://res.cloudinary.com/dza7lstvk/image/upload/v1745249064/Medusa%20Resources/Screenshot_2025-04-21_at_6.24.00_PM_peotrd.png) - -In the next step, you'll show the saved payment methods to the customer during checkout and allow them to select one of them. - -*** - -## Step 5: Use Saved Payment Methods During Checkout - -In this step, you'll customize the checkout flow in the Next.js Starter Storefront to show the saved payment methods to the customer and allow them to select one of them to place the order. - -### Retrieve Saved Payment Methods - -To retrieve the saved payment methods, you'll add a server function that retrieves the customer's saved payment methods from the API route you created earlier. - -Add the following in `src/lib/data/payment.ts`: - -```ts title="src/lib/data/payment.ts" badgeLabel="Storefront" badgeColor="blue" highlights={paymentHighlights} -export type SavedPaymentMethod = { - id: string - provider_id: string - data: { - card: { - brand: string - last4: string - exp_month: number - exp_year: number - } - } -} - -export const getSavedPaymentMethods = async (accountHolderId: string) => { - const headers = { - ...(await getAuthHeaders()), - } - - return sdk.client.fetch<{ - payment_methods: SavedPaymentMethod[] - }>( - `/store/payment-methods/${accountHolderId}`, - { - method: "GET", - headers, - } - ).catch(() => { - return { - payment_methods: [], - } - }) -} -``` - -You define a type for the retrieved payment methods. It contains the following properties: - -- `id`: The ID of the payment method in the third-party provider. -- `provider_id`: The ID of the provider in the Medusa application, such as Stripe's ID. -- `data`: Additional data retrieved from the third-party provider related to the saved payment method. The type is modeled after the data returned by Stripe, but you can change it to match other payment providers. - -You also create a `getSavedPaymentMethods` function that retrieves the saved payment methods from the API route you created earlier. The function accepts the account holder ID as a parameter and returns the saved payment methods. - -### Add Saved Payment Methods Component - -Next, you'll add the component that shows the saved payment methods and allows the customer to select one of them. - -The component that shows the Stripe card element is defined in `src/modules/checkout/components/payment-container/index.tsx`. So, you'll define the component for the saved payment methods in the same file. - -Start by adding the following import statements at the top of the file: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import { Button } from "@medusajs/ui" -import { useEffect, useState } from "react" -import { HttpTypes } from "@medusajs/types" -import { SavedPaymentMethod, getSavedPaymentMethods } from "@lib/data/payment" -import { initiatePaymentSession } from "../../../../lib/data/cart" -import { capitalize } from "lodash" -``` - -Then, update the `PaymentContainerProps` type to include the payment session and cart details: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -type PaymentContainerProps = { - // ... - paymentSession?: HttpTypes.StorePaymentSession - cart: HttpTypes.StoreCart -} -``` - -You'll need these details to find which saved payment method the customer selected, and to initiate a new payment session for the cart when the customer chooses a saved payment method. - -Next, add the following component at the end of the file: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeSavedPaymentMethodsHighlights} -const StripeSavedPaymentMethodsContainer = ({ - paymentSession, - setCardComplete, - setCardBrand, - setError, - cart, -}: { - paymentSession?: HttpTypes.StorePaymentSession - setCardComplete: (complete: boolean) => void - setCardBrand: (brand: string) => void - setError: (error: string | null) => void - cart: HttpTypes.StoreCart -}) => { - const [savedPaymentMethods, setSavedPaymentMethods] = useState< - SavedPaymentMethod[] - >([]) - const [selectedPaymentMethod, setSelectedPaymentMethod] = useState< - string | undefined - >( - paymentSession?.data?.payment_method_id as string | undefined - ) - - useEffect(() => { - const accountHolderId = ( - paymentSession?.context?.account_holder as Record - ) - ?.id - - if (!accountHolderId) { - return - } - - getSavedPaymentMethods(accountHolderId) - .then(({ payment_methods }) => { - setSavedPaymentMethods(payment_methods) - }) - }, [paymentSession]) - - useEffect(() => { - if (!selectedPaymentMethod || !savedPaymentMethods.length) { - setCardComplete(false) - setCardBrand("") - setError(null) - return - } - const selectedMethod = savedPaymentMethods.find( - (method) => method.id === selectedPaymentMethod - ) - - if (!selectedMethod) { - return - } - - setCardBrand(capitalize(selectedMethod.data.card.brand)) - setCardComplete(true) - setError(null) - }, [selectedPaymentMethod, savedPaymentMethods]) - - const handleSelect = async (method: SavedPaymentMethod) => { - // initiate a new payment session with the selected payment method - await initiatePaymentSession(cart, { - provider_id: method.provider_id, - data: { - payment_method_id: method.id, - }, - }).catch((error) => { - setError(error.message) - }) - - setSelectedPaymentMethod(method.id) - } - - if (!savedPaymentMethods.length) { - return <> - } - - // TODO add return statement -} -``` - -You define a `StripeSavedPaymentMethodsContainer` component that accepts the following props: - -- `paymentSession`: The cart's current payment session. -- `setCardComplete`: A function to tell parent components whether the cart or payment method selection is complete. This allows the customer to proceed to the next step in the checkout flow. -- `setCardBrand`: A function to set the brand of the selected payment method. This is useful to show the brand of the selected payment method in review sections of the checkout flow. -- `setError`: A function to set the error message in case of an error. -- `cart`: The cart's details. - -In the component, you define a state variable to store the saved payment methods and another one to store the selected payment method. - -Then, you use the `useEffect` hook to retrieve the saved payment methods for the account holder set in the cart's payment session. You use the `getSavedPaymentMethods` function you created earlier to retrieve the saved payment methods. - -You also use another `useEffect` hook that is executed when the selected payment method changes. In this hook, you check if the selected payment method is valid and set the card brand and completion status accordingly. - -Finally, you define a `handleSelect` function that you'll execute when the customer selects a saved payment method. It creates a new payment session with the selected payment method. - -To show the saved payment methods, replace the `TODO` with the following `return` statement: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -
- - Choose a saved payment method: - - {savedPaymentMethods.map((method) => ( -
handleSelect(method)} - > -
- { - if (e.target.checked) { - handleSelect(method) - } - }} - /> -
- - {capitalize(method.data.card.brand)} •••• {method.data.card.last4} - - - Expires {method.data.card.exp_month}/{method.data.card.exp_year} - -
-
-
- ))} -
-) -``` - -You display the saved payment methods as radio buttons. When the customer selects one of them, you execute the `handleSelect` function to initiate a new payment session with the selected payment method. - -### Modify Existing Stripe Element - -Now that you have the component to show the saved payment methods, you need to modify the existing Stripe element to allow customers to select an existing payment method or enter a new one. - -In the same `src/modules/checkout/components/payment-container/index.tsx` file, expand the new `paymentSession` and `cart` props of the `StripeCardContainer` component: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -export const StripeCardContainer = ({ - // ... - paymentSession, - cart, -}: Omit & { - // ... -}) => { - // ... -} -``` - -Then, add a new state variable that keeps track of whether the customer is using a saved payment method or entering a new one: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const [isUsingSavedPaymentMethod, setIsUsingSavedPaymentMethod] = useState( - paymentSession?.data?.payment_method_id !== undefined -) -``` - -Next, add a function that resets the payment session when the customer switches between saved and new payment methods: - -```ts title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const handleRefreshSession = async () => { - await initiatePaymentSession(cart, { - provider_id: paymentProviderId, - }) - setIsUsingSavedPaymentMethod(false) -} -``` - -This function initiates a new payment session for the cart and disables the `isUsingSavedPaymentMethod` state variable. - -Finally, replace the `return` statement of the `StripeCardContainer` component with the following: - -```tsx title="src/modules/checkout/components/payment-container/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={stripeCardReturnHighlights} -return ( - - {selectedPaymentOptionId === paymentProviderId && - (stripeReady ? ( -
- - {isUsingSavedPaymentMethod && ( - - )} - {!isUsingSavedPaymentMethod && ( - <> - - Enter your card details: - - { - setCardBrand( - e.brand && e.brand.charAt(0).toUpperCase() + e.brand.slice(1) - ) - setError(e.error?.message || null) - setCardComplete(e.complete) - }} - /> - - )} -
- ) : ( - - ))} - -) -``` - -You update the `return` statement to: - -- Pass the new `paymentSession` and `cart` props to the `PaymentContainer` component. -- Show the `StripeSavedPaymentMethodsContainer` component before Stripe's card element. -- Add a button that's shown when the customer selects a saved payment method. The button allows the customer to switch back to entering a new payment method. - -The existing Stripe element in checkout will now show the saved payment methods to the customer along with the component to enter a card's details. - -Since you added new props to the `StripeCardContainer` and `PaymentContainer` components, you need to update other components that use them to pass the props. - -In `src/modules/checkout/components/payment/index.tsx`, find usages of `StripeCardContainer` and `PaymentContainer` in the return statement and add the `paymentSession` and `cart` props: - -```tsx title="src/modules/checkout/components/payment/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["5"], ["6"], ["11"], ["12"]]} -
- {isStripeFunc(paymentMethod.id) ? ( - - ) : ( - - )} -
-``` - -### Support Updating Stripe's Client Secret - -The Next.js Starter Storefront uses Stripe's `Elements` component to wrap the payment elements. The `Elements` component requires a `clientSecret` prop, which is available in the cart's payment session. - -With the recent changes, the client secret will be updated whenever a payment session is initiated, such as when the customer selects a saved payment method. However, the `options.clientSecret` prop of the `Elements` component is immutable, meaning that it cannot be changed after the component is mounted. - -To force the component to re-mount and update the `clientSecret` prop, you can add a `key` prop to the `Elements` component. The `key` prop ensures that the `Elements` component re-mounts whenever the client secret changes, allowing Stripe to process the updated payment session. - -In `src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx`, find the `Elements` component in the `return` statement and add the `key` prop: - -```tsx title="src/modules/checkout/components/payment-wrapper/stripe-wrapper.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["4"]]} - - {children} - -``` - -You set the `key` prop to the client secret, which forces the `Elements` component to re-mount whenever the client secret changes. - -### Support Payment with Saved Payment Method - -The last change you need to make ensures that the customer can place an order with a saved payment method. - -When the customer places the order, and they've chosen Stripe as a payment method, the Next.js Starter Storefront uses Stripe's `confirmCardPayment` method to confirm the payment. This method accepts either the ID of a saved payment method, or the details of a new card. - -So, you need to update the `confirmCardPayment` usage to support passing the ID of the selected payment method if the customer has selected one. - -In `src/modules/checkout/components/payment-button/index.tsx`, find the `handlePayment` method and update its first `if` condition: - -```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" -if (!stripe || !elements || (!card && !session?.data.payment_method_id) || !cart) { - setSubmitting(false) - return -} -``` - -This allows the customer to place their order if they have selected a saved payment method but have not entered a new card. - -Then, find the usage of `confirmCardPayment` in the `handlePayment` function and change it to the following: - -```ts title="src/modules/checkout/components/payment-button/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={confirmPaymentHighlights} -await stripe -.confirmCardPayment(session?.data.client_secret as string, { - payment_method: session?.data.payment_method_id as string || { - card: card!, - billing_details: { - name: - cart.billing_address?.first_name + - " " + - cart.billing_address?.last_name, - address: { - city: cart.billing_address?.city ?? undefined, - country: cart.billing_address?.country_code ?? undefined, - line1: cart.billing_address?.address_1 ?? undefined, - line2: cart.billing_address?.address_2 ?? undefined, - postal_code: cart.billing_address?.postal_code ?? undefined, - state: cart.billing_address?.province ?? undefined, - }, - email: cart.email, - phone: cart.billing_address?.phone ?? undefined, - }, - }, -}) -.then(({ error, paymentIntent }) => { - if (error) { - const pi = error.payment_intent - - if ( - (pi && pi.status === "requires_capture") || - (pi && pi.status === "succeeded") - ) { - onPaymentCompleted() - } - - setErrorMessage(error.message || null) - return - } - - if ( - (paymentIntent && paymentIntent.status === "requires_capture") || - paymentIntent.status === "succeeded" - ) { - return onPaymentCompleted() - } - - return -}) -``` - -In particular, you're changing the `payment_method` property to either be the ID of the selected payment method, or the details of a new card. This allows the customer to place an order with either a saved payment method or a new one. - -### Test it Out - -You can now test out placing orders with a saved payment method. - -To do that, start the Medusa application by running the following command in the Medusa application's directory: - -```bash npm2yarn -npm run dev -``` - -Then, start the Next.js Starter Storefront by running the following command in the storefront's directory: - -```bash npm2yarn -npm run dev -``` - -In the Next.js Starter Storefront, login with the customer account you created earlier and add a product to the cart. - -Then, proceed to the checkout flow. In the payment step, you should see the saved payment method you used earlier. You can select it and place the order. - -![Saved payment method in checkout](https://res.cloudinary.com/dza7lstvk/image/upload/v1745308047/Medusa%20Resources/Screenshot_2025-04-21_at_4.07.34_PM_krudjq.png) - -Once the order is placed successfully, you can check it in the Medusa Admin dashboard.

You can use [Stripe's APIs](https://docs.stripe.com/api/payment_methods/detach) in the storefront or add an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md) in Medusa to delete the saved payment method. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - -# Implement Phone Authentication and Integrate Twilio SMS - -In this tutorial, you will learn how to implement phone number authentication in your Medusa application. - -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 authentication with custom providers and for custom user or actor types. - -In this tutorial, you'll learn how to implement a custom authentication provider that allows customers to log in with their phone number. You'll also integrate [Twilio](https://www.twilio.com/en-us/messaging/channels/sms) to send SMS messages to those customers with the one-time password (OTP) for authentication. - -Twilio is just one option to deliver the OTP to the customer. You can integrate a different SMS provider or use a different method to send OTPs. - -## Summary - -By following this tutorial, you will learn how to: - -- Install and set up Medusa. -- Implement a custom phone authentication provider. -- Integrate Twilio to send OTPs by SMS. -- Customize the Next.js Starter Storefront to allow customers to log in with their phone numbers. - -You can follow this tutorial whether you're new to Medusa or an advanced Medusa developer. - -![Diagram showcasing the phone authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1747744941/Medusa%20Resources/phone-auth-overview_bt5yrp.jpg) - -While this tutorial focuses on supporting phone authentication for customers, you can use the authentication provider for any actor type, such as admin user or vendor.

Then, when asked whether you want to install the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md), choose Yes. - -Afterward, the installation process will start, which will install the Medusa application in a directory with your project's name, and the Next.js Starter Storefront in a separate directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more in [Medusa's Architecture documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user. Enter the user's credentials and submit the form. 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: Implement Phone Authentication Module Provider - -In Medusa, you integrate custom authentication providers by creating an [Authentication Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-providers/index.html.md). Then, you can use that provider to authenticate users using custom logic. - -In this step, you'll create a Phone Authentication Module Provider that allows users to log in with their phone numbers and an OTP. Later, you'll integrate Twilio to send the OTPs to the users, and customize the storefront to allow customers to log in with their phone numbers. - -An Authentication Module Provider doesn't need to handle storing and managing specific user details, such as creating customers or admin users. Instead, it only focuses on the logic of authenticating a type of user using custom logic or integration. You can learn more in the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) documentation. - -### Prerequisite: Install jsonwebtoken - -In the Phone Authentication Module Provider, you'll use the `jsonwebtoken` package to sign and verify the OTPs. - -To install the package, run the following command in the Medusa application directory: - -```bash npm2yarn -npm install jsonwebtoken -npm install @types/jsonwebtoken --save-dev -``` - -### a. Create Module Directory - -Modules are created under the `src/modules` directory. So, start by creating the directory `src/modules/phone-auth`. - -### b. Create Auth Module Provider Service - -A module has a service that contains its logic. For Authentication Module Providers, the service implements the logic to authenticate users. - -To create the service of the Phone Authentication Module Provider, create the file `src/modules/phone-auth/service.ts` with the following content: - -```ts title="src/modules/phone-auth/service.ts" highlights={phoneAuthServiceHighlights} -import { - AbstractAuthModuleProvider, - AbstractEventBusModuleService, -} from "@medusajs/framework/utils" -import { - Logger, -} from "@medusajs/types" - -type InjectedDependencies = { - logger: Logger - event_bus: AbstractEventBusModuleService -} - -type Options = { - jwtSecret: string -} - -class PhoneAuthService extends AbstractAuthModuleProvider { - static DISPLAY_NAME = "Phone Auth" - static identifier = "phone-auth" - private options: Options - private logger: Logger - private event_bus: AbstractEventBusModuleService - - constructor(container: InjectedDependencies, options: Options) { - // @ts-ignore - super(...arguments) - - this.options = options - this.logger = container.logger - this.event_bus = container.event_bus - } -} - -export default PhoneAuthService -``` - -An Authentication Module Provider's service must extend the `AbstractAuthModuleProvider` class. You'll get a type error about implementing the abstract methods of that class, which you'll add in the next steps. - -An Authentication Module Provider must also have the following static properties: - -- `identifier`: A unique identifier for the provider. -- `DISPLAY_NAME`: A human-readable name for the provider. This name is used for display purposes. - -A module provider's constructor receives two parameters: - -- `container`: The [module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md) that contains Framework resources available to the module. You access the following resources: - - `logger`: A [Logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) class to log debug messages. - - `event_bus`: The [Event Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/event/index.html.md)'s service to emit events. -- `options`: Options that are passed to the module provider when it's registered in Medusa's configurations. You define the following option: - - `jwtSecret`: A secret used to sign and verify the OTPs. - -You'll learn how to set this option when you [add the module provider to Medusa's configurations](#h-add-module-provider-to-medusas-configurations). - -In the constructor, you set the class's properties to the injected dependencies and options. - -In the next sections, you'll implement the methods of the `AbstractAuthModuleProvider` class. - -Refer to the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider/index.html.md) guide for detailed information about the methods. - -### c. Implement validateOptions Method - -The `validateOptions` method is used to validate the options passed to the module provider. If the method throws an error, the Medusa application won't start. - -So, add the `validateOptions` method to the `PhoneAuthService` class: - -```ts title="src/modules/phone-auth/service.ts" -// other imports... -import { - MedusaError, -} from "@medusajs/framework/utils" - -class PhoneAuthService extends AbstractAuthModuleProvider { - // ... - static validateOptions(options: Record): void | never { - if (!options.jwtSecret) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "JWT secret is required" - ) - } - } -} -``` - -The `validateOptions` method receives the options passed to the module provider as a parameter. - -In the method, you throw an error if the `jwtSecret` option is not set. - -### d. Implement register Method - -When a customer (or another actor type) registers in your application, they must also have an [auth identity](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-identity-and-actor-types/index.html.md) that allows them to login. - -The `register` method of an auth provider uses custom logic to create the auth identity for the actor type (such as customer). In the method, you can perform custom validation and specify the custom authentication details to store for the user's auth identity. - -Medusa uses the `register` method to create an auth identity that will be associated with the customer when they register. You can learn more in the [Authentication Flows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-flows/index.html.md) documentation. - -![Diagram showcasing the relation between a customer and auth identity](https://res.cloudinary.com/dza7lstvk/image/upload/v1747747179/Medusa%20Resources/customer-auth-identity_je1bvh.jpg) - -So, add the `register` method to the `PhoneAuthService` class: - -```ts title="src/modules/phone-auth/service.ts" highlights={registerHighlights} -// other imports... -import { - AuthenticationInput, - AuthIdentityProviderService, - AuthenticationResponse, -} from "@medusajs/types" - -class PhoneAuthService extends AbstractAuthModuleProvider { - // ... - async register( - data: AuthenticationInput, - authIdentityProviderService: AuthIdentityProviderService - ): Promise { - const { phone } = data.body || {} - - if (!phone) { - return { - success: false, - error: "Phone number is required", - } - } - - try { - await authIdentityProviderService.retrieve({ - entity_id: phone, - }) - - return { - success: false, - error: "User with phone number already exists", - } - } catch (error) { - const user = await authIdentityProviderService.create({ - entity_id: phone, - }) - - return { - success: true, - authIdentity: user, - } - } - } -} -``` - -#### Parameters - -The `register` method receives an object parameter with the following properties: - -- `data`: An object containing properties like `body` that holds request-body parameters. Clients will pass relevant authentication data, such as the user's phone number, in the request body. -- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. - -The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#register/index.html.md) guide. - -#### Method Logic - -In the method, you extract the `phone` property from the request body, and return an error if it's not provided. You also return an error if another user is using the same phone number. - -Otherwise, you create a new auth identity for the user. You set the phone number as the `entity_id` of the auth identity, which is a unique identifier. - -#### Return Value - -Finally, you return an object with the following properties: - -- `success`: A boolean indicating whether the registration was successful. -- `authIdentity`: The created auth identity of the user. This property is only set if the registration was successful. -- `error`: An error message if the registration failed. - -### e. Implement authenticate Method - -When a customer (or another actor type) logs in, the `authenticate` method of an auth provider is called. This method uses custom logic to authenticate the user. - -Authentication providers may implement one of the following flows: - -- Direct authentication, where the user is authenticated using this method only. For example, authenticating with an email and password. -- Authentication with callback verification, where the user is authenticated using this method and then a callback is used to verify additional information. - -For the Phone Authentication Module Provider, you'll implement the second flow. The user will first be authenticated using the `authenticate` method to make sure the user exists and generate an OTP. Then, they need to supply the OTP to verify their identity. - -![Diagram showcasing authentication with callback verification](https://res.cloudinary.com/dza7lstvk/image/upload/v1747749683/Medusa%20Resources/authentication-flow_ey59hw.jpg) - -So, add the `authenticate` method to the `PhoneAuthService` class: - -```ts title="src/modules/phone-auth/service.ts" highlights={authenticateHighlights} -// other imports... -import { - AuthIdentityDTO, -} from "@medusajs/types" -import jwt from "jsonwebtoken" - -class PhoneAuthService extends AbstractAuthModuleProvider { - // ... - async authenticate( - data: AuthenticationInput, - authIdentityProviderService: AuthIdentityProviderService - ): Promise { - const { phone } = data.body || {} - - if (!phone) { - return { - success: false, - error: "Phone number is required", - } - } - - try { - await authIdentityProviderService.retrieve({ - entity_id: phone, - }) - } catch (error) { - return { - success: false, - error: "User with phone number does not exist", - } - } - - const { hashedOTP, otp } = await this.generateOTP() - - await authIdentityProviderService.update(phone, { - provider_metadata: { - otp: hashedOTP, - }, - }) - - await this.event_bus.emit({ - name: "phone-auth.otp.generated", - data: { - otp, - phone, - }, - }, {}) - - return { - success: true, - location: "otp", - } - } - - async generateOTP(): Promise<{ hashedOTP: string, otp: string }> { - // Generate a 6-digit OTP - const otp = Math.floor(100000 + Math.random() * 900000).toString() - - // for debug - this.logger.info(`Generated OTP: ${otp}`) - - const hashedOTP = jwt.sign({ otp }, this.options.jwtSecret, { - expiresIn: "60s", - }) - - return { hashedOTP, otp } - } -} -``` - -You add two methods: the `authenticate` method, and a helper `generateOTP` method. - -#### authenticate Parameters - -The `authenticate` method receives an object parameter with the following properties: - -- `data`: An object containing properties like `body` that holds request-body parameters. Clients will pass relevant authentication data, such as the user's phone number, in the request body. -- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. - -The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#authenticate/index.html.md) guide. - -#### authenticate Logic - -In the method, you return an error if the `phone` property is not provided in the request body, or if a user with that phone number doesn't exist. - -Next, you generate a 6-digit OTP using the `generateOTP` method. Notice that you currently log the OTP for debugging purposes. You can remove this line later once you integrate Twilio. - -The OTP is hashed and stored in the `provider_metadata` property of the user's auth identity. The `provider_metadata` property is a JSON object that stores additional information about the auth identity. - -Then, you emit an event with the generated OTP and the user's phone number. This allows you later to handle the event and send the OTP to the user using services like Twilio. - -#### authenticate Return Value - -Finally, you return an object with the following properties: - -- `success`: A boolean indicating whether the authentication was successful. -- `location`: A string indicating a URL to perform additional actions in. In this case, you set the location to `otp`, indicating that the user should verify with the OTP. -- `error`: An error message if the authentication failed. - -### f. Implement validateCallback Method - -When an authentication provider requires a callback to verify the user, the Medusa application calls the `validateCallback` method. - -You can use this method to verify the OTP that the user entered. If valid, you return the logged in user, and the Medusa application will return a JWT token that the user can use to authenticate in the application. - -![Diagram showcasing how callback verification fits in the authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1747749734/Medusa%20Resources/callback-flow_yney5a.jpg) - -So, add the `validateCallback` method to the `PhoneAuthService` class: - -```ts title="src/modules/phone-auth/service.ts" highlights={validateCallbackHighlights} -class PhoneAuthService extends AbstractAuthModuleProvider { - // ... - async validateCallback( - data: AuthenticationInput, - authIdentityProviderService: AuthIdentityProviderService - ): Promise { - const { phone, otp } = data.query || {} - - if (!phone || !otp) { - return { - success: false, - error: "Phone number and OTP are required", - } - } - - const user = await authIdentityProviderService.retrieve({ - entity_id: phone, - }) - - if (!user) { - return { - success: false, - error: "User with phone number does not exist", - } - } - - // verify that OTP is correct - const userProvider = user.provider_identities?.find((provider) => provider.provider === this.identifier) - if (!userProvider || !userProvider.provider_metadata?.otp) { - return { - success: false, - error: "User with phone number does not have a phone auth provider", - } - } - - try { - const decodedOTP = jwt.verify( - userProvider.provider_metadata.otp as string, - this.options.jwtSecret - ) as { otp: string } - - if (decodedOTP.otp !== otp) { - throw new Error("Invalid OTP") - } - } catch (error) { - return { - success: false, - error: error.message || "Invalid OTP", - } - } - - const updatedUser = await authIdentityProviderService.update(phone, { - provider_metadata: { - otp: null, - }, - }) - - return { - success: true, - authIdentity: updatedUser, - } - } -} -``` - -#### Parameters - -The `validateCallback` method receives an object parameter with the following properties: - -- `data`: An object containing properties like `query` that holds query parameters. Clients will pass relevant authentication data, such as the user's phone number and OTP, in the request query. -- `authIdentityProviderService`: A service injected by the [Auth Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/index.html.md) that allows you to manage auth identities. - -The method receives other parameters, which you can find in the [Create Auth Module Provider](https://docs.medusajs.com/references/auth/provider#validatecallback/index.html.md) guide. - -#### Method Logic - -In the method, you return an error if the phone and otp aren't provided in the request query, or if a user with that phone number doesn't exist. - -Next, you verify that the OTP provided by the user is correct. You retrieve the hashed OTP from the `provider_metadata` property of the user's auth identity. If the OTP is not valid, you return an error. - -Since you set the hash expiration to 60 seconds, the OTP will be valid for 60 seconds. After that, the user will need to request a new OTP. - -After that, you update the user's auth identity to remove the OTP from the `provider_metadata` property. - -#### Return Value - -Finally, you return an object with the following properties: - -- `success`: A boolean indicating whether the authentication was successful. -- `authIdentity`: The user's auth identity. This property is only set if the authentication was successful. -- `error`: An error message if the authentication failed. - -### g. Export Module Definition - -You've now finished implementing the necessary methods for the Phone Authentication Module Provider. - -The final piece to a module is its definition, which you export in an `index.ts` file at the module's root directory. This definition tells Medusa the name of the module, its service, and optionally its loaders. - -To create the module's definition, create the file `src/modules/phone-auth/index.ts` with the following content: - -```ts title="src/modules/phone-auth/index.ts" -import PhoneAuthService from "./service" -import { - ModuleProvider, - Modules, -} from "@medusajs/framework/utils" - -export default ModuleProvider(Modules.AUTH, { - services: [PhoneAuthService], -}) -``` - -You use `ModuleProvider` from the Modules SDK to create the module provider's definition. It accepts two parameters: - -1. The name of the module that this provider belongs to, which is `Modules.AUTH` in this case. -2. An object with a required property `services` indicating the module provider's services. Each of these services will be registered as authentication providers in Medusa. - -### h. Add Module Provider 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: - -```ts title="medusa-config.ts" -// other imports... -import { Modules, ContainerRegistrationKeys } from "@medusajs/framework/utils" - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/auth", - dependencies: [ - Modules.CACHE, - ContainerRegistrationKeys.LOGGER, - Modules.EVENT_BUS, - ], - options: { - providers: [ - // default provider - { - resolve: "@medusajs/medusa/auth-emailpass", - id: "emailpass", - }, - { - resolve: "./src/modules/phone-auth", - id: "phone-auth", - options: { - jwtSecret: process.env.PHONE_AUTH_JWT_SECRET || "supersecret", - }, - }, - ], - }, - }, - ], -}) -``` - -To pass an Auth Module Provider to the Auth Module, you add the `modules` property to the Medusa configuration and pass the Auth Module in its value. - -The Auth Module accepts a `dependencies` option, allowing you to inject dependencies into the containers of the module and its providers. The Auth Module requires passing the [Cache Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/cache/index.html.md) and Logger, but you also inject the `event_bus` dependency to use the Event Module's service in the Phone Authentication Module Provider. - -The Auth Module also accepts a `providers` option, which is an array of Auth Module Providers to register. You register the `emailpass` provider, which is registered by default when you don't provide any other providers. - -To register the Phone Authentication Module Provider, you add an object to the `providers` array with the following properties: - -- `resolve`: The NPM package or path to the module provider. In this case, it's the path to the `src/modules/phone-auth` directory. -- `id`: The ID of the module provider. The auth provider is then registered with the ID `au_{id}`. -- `options`: The options to pass to the module provider. These are the options you defined in the `Options` interface of the module provider's service. - -### i. Enable Phone Authentication for Customers - -By default, customers and admin users can be authenticated using the `emailpass` provider. When you add a new provider, you need to specify which actor types can use it. - -In `medusa-config.ts`, add to `projectConfig.http` a new `authMethodsPerActor` property: - -```ts title="medusa-config.ts" highlights={authMethodsPerActorHighlights} -module.exports = defineConfig({ - projectConfig: { - // ... - http: { - // ... - authMethodsPerActor: { - user: ["emailpass"], - customer: ["emailpass", "phone-auth"], - }, - }, - }, - // ... -}) -``` - -The `authMethodsPerActor` property is an object whose keys are actor types. The values are arrays of authentication method IDs that can be used for that actor type. - -In this case, you enable the `phone-auth` provider for customers. You can also enable it for other actor types, such as admin users or vendors. - -### Test Out Phone Authentication - -In this section, you'll test out the Phone Authentication Module Provider using Medusa's API routes. You can, instead, test it out later using the [Next.js Starter Storefront](#step-4-use-phone-authentication-in-the-nextjs-starter-storefront). - -First, start the Medusa application with the following command: - -```bash npm2yarn -npm run start -``` - -#### Prerequisite: Retrieve Publishable API Key - -Before you start testing the authentication provider using the API routes, you need to retrieve your application's publishable API key. This key is necessary to send requests to API routes starting with `/store`. - -To retrieve the publishable API key: - -1. Open the Medusa Admin dashboard at `http://localhost:9000/admin` and log in. -2. Go to Settings -> Publishable API Keys. -3. Click on the API key in the table. -4. In its details page, click on the API key to copy it. - -![Publishable API Key page with the API key clicked](https://res.cloudinary.com/dza7lstvk/image/upload/fl_lossy/f_auto/r_16/ar_16:9,c_pad/v1/User%20Guide/Screenshot_2025-02-25_at_6.14.15_PM_muwq9e.png) - -#### a. Retrieve Registration Token - -The first step is to retrieve a registration token for a new customer. This token will allow them to register in the application. - -To retrieve the registration token, send a `POST` request to `/auth/customer/phone-auth/register`: - -```bash -curl -X POST 'http://localhost:9000/auth/customer/phone-auth/register' \ ---header 'Content-Type: application/json' \ ---data '{ - "phone": "+19077890116" -}' -``` - -Make sure to replace the phone number with the one you want to use. - -This will return a `token` in the response: - -```json title="Example Response" -{ - "token": "123..." -} -``` - -#### b. Register Customer - -Next, you'll register the customer using the [Register Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You'll pass the registration token you received in the previous step in the header of this request. - -So, send a `POST` request to `/store/customers`: - -```bash -curl -X POST 'http://localhost:9000/store/customers' \ ---header 'x-publishable-api-key: {publishable_api_key}' \ ---header 'Content-Type: application/json' \ ---header 'Authorization: Bearer {reg_token}' \ ---data-raw '{ - "email": "+19077890116@gmail.com", - "phone": "19077890116", - "first_name": "John", - "last_name": "Smith" -}' -``` - -Make sure to replace: - -- `{publishable_api_key}` with the publishable API key you retrieved from the Medusa Admin dashboard. -- `{reg_token}` with the registration token you received in the previous step. -- The customer details in the request body with the ones you want to use. Use the same phone number you used in the previous step. - - You pass the email because it's required by the [Register Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You set it to the phone number with a `gmail.com` domain. - -The request will return the created customer's details: - -```json title="Example Response" -{ - "customer": { - "id": "cus_01JVPESW5SM1MSVPNM2MSC0ZEC", - "email": "+19077890116@gmail.com", - "company_name": null, - "first_name": "John", - "last_name": "Smith", - "phone": "19077890116", - "metadata": null, - "has_account": true, - "deleted_at": null, - "created_at": "2025-05-20T09:01:13.273Z", - "updated_at": "2025-05-20T09:01:13.273Z", - "addresses": [] - } -} -``` - -The customer can now authenticate using the phone number and OTP. - -#### c. Authenticate Customer - -Next, you'll authenticate the customer using the [Authenticate Customer](https://docs.medusajs.com/api/store#auth_postactor_typeauth_provider) API route. This would send the customer an OTP to their phone number (which you'll implement in the next step). - -So, send a `POST` request to `/auth/customer/phone-auth`: - -```bash -curl -X POST 'http://localhost:9000/auth/customer/phone-auth' \ ---header 'Content-Type: application/json' \ ---data '{ - "phone": "+19077890116" -}' -``` - -Make sure to replace the phone number with the one you used to register the customer. - -This will return a `location` in the response: - -```json title="Example Response" -{ - "location": "otp" -} -``` - -Indicating that the user should verify their OTP. - -You can also use this route to resend the OTP if the user didn't receive it or if a minute has passed since the last OTP was sent. - -#### d. Verify OTP - -If you check the logs of the Medusa application, you'll see that the OTP was generated and logged: - -```bash -info: Generated OTP: 576794 -``` - -As mentioned before, this is only for debugging purposes. In the next step, you'll implement the logic to send the OTP to the user using Twilio. - -So, to verify the OTP, you'll send a request to the [Verify Callback API route](https://docs.medusajs.com/api/store#auth_postactor_typeauth_providercallback): - -```bash -curl -X POST 'http://localhost:9000/auth/customer/phone-auth/callback?phone=%2B19077890116&otp=476588' -``` - -You pass the following query parameters: - -- `phone`: The phone number of the customer. Make sure to use the same phone number you used to register the customer, and to encode it. For example, the `+` sign should be encoded as `%2B`. -- `otp`: The OTP that the customer received. Make sure to use the same OTP shown in the logs. - -If the OTP is valid, you'll receive a JWT token in the response: - -```json title="Example Response" -{ - "token": "123..." -} -``` - -You can use this token to authenticate the customer in the application. For example, you can use the token to [retrieve the customer's details](https://docs.medusajs.com/api/store#customers_getcustomersme). - -If the OTP has expired, send a request to the [Authenticate Customer](#c-authenticate-customer) API route to generate a new OTP - -*** - -## Step 3: Integrate Twilio SMS - -Similar to the Auth Module, the [Notification Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/notification/index.html.md) allows registering custom providers to send notifications, such as SMS or email. - -In this step, you'll create a Twilio Notification Module Provider, then use it to send the OTP to the customer. - -### Prerequisites - -- [Twilio Account](https://console.twilio.com/) -- [Twilio From Phone Number](https://www.twilio.com/docs/phone-numbers) -- [Twilio Account SID, which you can retrieve from the Twilio Console homepage.](https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account-namer#console-dashboard-home-page) -- [Twilio Auth Token, which you can retrieve from the Twilio Console homepage.](https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account-namer#console-dashboard-home-page) - -### a. Install Twilio SDK - -Before you start implementing the Twilio Notification Module Provider, install the Twilio SDK to interact with the Twilio API. - -Run the following command in the Medusa application directory: - -```bash npm2yarn -npm install twilio -``` - -You'll use the Twilio SDK in the Notification Module Provider's service. - -### b. Create Module Directory - -Create the directory `src/modules/twilio-sms` to create the Twilio Notification Module Provider. - -### c. Create Notification Module Provider Service - -A Notification Module Provider has a service that contains the sending logic. The service must extend the `AbstractNotificationProviderService` class. - -So, create the file `src/modules/twilio-sms/service.ts` with the following content: - -```ts title="src/modules/twilio-sms/service.ts" highlights={twilioSmsServiceHighlights} -import { - AbstractNotificationProviderService, -} from "@medusajs/framework/utils" -import { Twilio } from "twilio" - -type InjectedDependencies = {} - -type TwilioSmsServiceOptions = { - accountSid: string - authToken: string - from: string -} - -class TwilioSmsService extends AbstractNotificationProviderService { - static readonly identifier = "twilio-sms" - private readonly client: Twilio - private readonly from: string - - constructor(container: InjectedDependencies, options: TwilioSmsServiceOptions) { - super() - - this.client = new Twilio(options.accountSid, options.authToken) - this.from = options.from - } -} -``` - -You'll get a type error about implementing the abstract methods of the `AbstractNotificationProviderService` class, which you'll add in the next steps. - -A Notification Module Provider must have an `identifier` static property, which is a unique identifier for the module. This identifier is used to register the module in the Medusa application. - -A module provider's constructor receives two parameters: - -- `container`: The [module's container](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md) that contains Framework resources available to the module. You don't need to access any resources for this provider. -- `options`: Options that are passed to the module provider when it's registered in Medusa's configurations. You define the following option: - - `accountSid`: The Twilio account SID. - - `authToken`: The Twilio auth token. - - `from`: The Twilio phone number to send the SMS from. - -You'll learn how to set these options when you [add the module provider to Medusa's configurations](#g-add-module-provider-to-medusas-configurations). - -In the constructor, you set the class's properties to the injected dependencies and options. - -In the next sections, you'll implement the methods of the `AbstractNotificationProviderService` class. - -Refer to the [Create Notification Module Provider](https://docs.medusajs.com/references/notification-provider-module/index.html.md) guide for detailed information about the methods. - -### d. Implement validateOptions Method - -The `validateOptions` method is used to validate the options passed to the module provider. If the method throws an error, the Medusa application won't start. - -So, add the `validateOptions` method to the `TwilioSmsService` class: - -```ts title="src/modules/twilio-sms/service.ts" -class TwilioSmsService extends AbstractNotificationProviderService { - // ... - static validateOptions(options: Record): void | never { - if (!options.accountSid) { - throw new Error("Account SID is required") - } - if (!options.authToken) { - throw new Error("Auth token is required") - } - if (!options.from) { - throw new Error("From is required") - } - } -} -``` - -The `validateOptions` method receives the options passed to the module provider as a parameter. - -In the method, you throw an error if any of the options are not set. - -### e. Implement send Method - -The only required method for a Notification Module Provider is the `send` method. When the Medusa application needs to send a notification using the provider's channel (such as SMS), it calls this method of the registered provider. - -So, add the `send` method to the `TwilioSmsService` class: - -```ts title="src/modules/twilio-sms/service.ts" highlights={sendHighlights} -// other imports... -import { - ProviderSendNotificationDTO, - ProviderSendNotificationResultsDTO, -} from "@medusajs/types" - -class TwilioSmsService extends AbstractNotificationProviderService { - // ... - async send( - notification: ProviderSendNotificationDTO - ): Promise { - const { to, content, template, data } = notification - const contentText = content?.text || await this.getTemplateContent( - template, data - ) - - const message = await this.client.messages.create({ - body: contentText, - from: this.from, - to, - }) - - return { - id: message.sid, - } - } - - async getTemplateContent( - template: string, - data?: Record | null - ): Promise { - switch (template) { - case "otp-template": - if (!data?.otp) { - throw new Error("OTP is required for OTP template") - } - - return `Your OTP is ${data.otp}` - default: - throw new Error(`Template ${template} not found`) - } - } -} -``` - -You implement the `send` method and a helper `getTemplateContent` method. - -#### send Parameters - -The `send` method receives an object parameter with the following properties: - -- `to`: The phone number to send the SMS to. -- `content`: An object containing the content of the SMS. The `text` property is the text to send. -- `template`: The template to use for the SMS. This is used to retrieve the fallback content of the SMS if `content.text` is not provided. -- `data`: An object containing the data to use in the template. This is used to replace placeholders in the template with actual values. - -The method receives other parameters, which you can find in the [Create Notification Module Provider](https://docs.medusajs.com/references/notification-provider-module#send/index.html.md) guide. - -#### send Method Logic - -In the method, you set the SMS content either to the `text` property of the `content` object or to the template content. You define a `getTemplateContent` method that retrieves the content for a template. - -Then, you use the `messages.create` method of the Twilio client to send the SMS. You pass the following parameters: - -- `body`: The content of the SMS. -- `from`: The Twilio phone number to send the SMS from. -- `to`: The phone number to send the SMS to. - -#### send Return Value - -Finally, you return an object that has an `id` property with the ID of the sent SMS. This ID is stored in the notification record in the database. - -### f. Export Module Definition - -You've now finished implementing the necessary methods for the Twilio Notification Module Provider. You only need to export its definition. - -To create the module's definition, create the file `src/modules/twilio-sms/index.ts` with the following content: - -```ts title="src/modules/twilio-sms/index.ts" -import { - ModuleProvider, - Modules, -} from "@medusajs/framework/utils" -import TwilioSMSNotificationService from "./service" - -export default ModuleProvider(Modules.NOTIFICATION, { - services: [TwilioSMSNotificationService], -}) -``` - -You use `ModuleProvider` from the Modules SDK to create the module provider's definition passing it two parameters: - -1. The name of the module that this provider belongs to, which is `Modules.NOTIFICATION` in this case. -2. An object with a required property `services` indicating the module provider's services. Each of these services will be registered as notification providers in Medusa. - -### g. Add Module Provider to Medusa's Configurations - -You'll now add the Twilio Notification Module Provider to Medusa's configurations to start using it. - -In `medusa-config.ts`, add the following to the `modules` property: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - // ... - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - // default provider - { - resolve: "@medusajs/medusa/notification-local", - id: "local", - options: { - name: "Local Notification Provider", - channels: ["feed"], - }, - }, - { - resolve: "./src/modules/twilio-sms", - id: "twilio-sms", - options: { - channels: ["sms"], - accountSid: process.env.TWILIO_ACCOUNT_SID, - authToken: process.env.TWILIO_AUTH_TOKEN, - from: process.env.TWILIO_FROM, - }, - }, - ], - }, - }, - ], -}) -``` - -You pass the Notification Module in the `modules` property to register the Twilio Notification Module Provider. - -The Notification Module accepts a `providers` option, which is an array of Notification Module Providers to register. You register the `local` provider, which is registered by default when you don't provide any other providers. - -To register the Twilio Notification Module Provider, you add an object with the following properties: - -- `resolve`: The path to the module provider. -- `id`: The ID of the module provider. The notification provider is then registered with the ID `np_{identifier}_{id}`. -- `options`: The options to pass to the module provider. These include the options you defined in the `Options` interface of the module provider's service. - - `channels`: The channels that the notification provider supports. In this case, you set it to `sms`, which is the channel used to send SMS notifications. - - `accountSid`: The Twilio account SID. - - `authToken`: The Twilio auth token. - - `from`: The Twilio phone number to send the SMS from. - -### h. Add Environment Variables - -To set the value of the Twilio options, add the following environment variables to your `.env` file: - -```shell title=".env" -TWILIO_ACCOUNT_SID=AC... -TWILIO_AUTH_TOKEN=05... -TWILIO_FROM=+1... -``` - -Where: - -- `TWILIO_ACCOUNT_SID`: The Twilio account SID. -- `TWILIO_AUTH_TOKEN`: The Twilio auth token. -- `TWILIO_FROM`: The Twilio phone number to send the SMS from. Make sure to use the phone number you purchased from Twilio. - -You can retrieve these information from the Twilio Console homepage. - -![Twilio console homepage showing the account SID, phone number, and auth token](https://res.cloudinary.com/dza7lstvk/image/upload/v1747736641/Medusa%20Resources/CleanShot_2025-05-20_at_13.22.55_2x_sztmfo.png) - -### i. Handle OTP Generated Event - -Now that you have integrated Twilio into Medusa, you can use it to send the OTP to the customer. To do that, you need to handle the `phone-auth.otp.generated` event that you emitted in the `authenticate` method of the Phone Authentication Module Provider. - -You can listen to events in a [subscriber](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that listens to events to perform actions when the event is emitted. - -In this step, you'll create a subscriber that listens to the `phone-auth.otp.generated` event and sends an SMS to the customer with the OTP. - -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 file `src/subscribers/send-otp.ts` with the following content: - -```ts title="src/subscribers/send-otp.ts" highlights={sendOtpHighlights} -import { - SubscriberArgs, - type SubscriberConfig, -} from "@medusajs/medusa" -import { Modules } from "@medusajs/framework/utils" - -export default async function sendOtpHandler({ - event: { data: { - phone, - otp, - } }, - container, -}: SubscriberArgs<{ phone: string, otp: string }>) { - const notificationModuleService = container.resolve( - Modules.NOTIFICATION - ) - - await notificationModuleService.createNotifications({ - to: phone, - channel: "sms", - template: "otp-template", - data: { - otp, - }, - }) -} - -export const config: SubscriberConfig = { - event: "phone-auth.otp.generated", -} -``` - -The subscriber file must export: - -- An asynchronous subscriber function that's executed whenever the associated event is triggered. -- A configuration object with an event property whose value is the event the subscriber is listening to, which is `phone-auth.otp.generated`. - -The subscriber function accepts an object with the following properties: - -- `event`: An object with the event's data payload. In the `authenticate` method, you emitted the event with the following data: - - `phone`: The phone number of the user. - - `otp`: The OTP that was generated. -- `container`: The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which you can use to resolve Framework and commerce resources. - -In the subscriber function, you resolve the Notification Module's service from the Medusa container. Then, you use its `createNotifications` method to send the OTP to the user. - -Under the hood, the Notification Module's service delegates the sending to the Notification Module Provider of the `sms` channel, which is the Twilio Notification Module Provider in this case. - -The `createNotifications` method accepts an object with the following properties: - -- `to`: The phone number to send the notification to. You use the phone number from the event's data payload. -- `channel`: The channel to use to send the notification, which is `sms`. -- `template`: The template to use for the notification content, which is `otp-template`. -- `data`: An object containing the data to use in the template. You pass the OTP to the template. - -### j. Test it Out - -To test out the Twilio Notification Module Provider, you can follow the steps in the [Test Out Phone Authentication](#test-out-phone-authentication) section. - -After you authenticate the customer, the OTP will be sent to the customer's phone number using Twilio. Then, you can use the OTP to verify the authentication and receive a JWT token. - -Alternatively, you can also test it out after customizing the Next.js Starter Storefront, which you'll do in the next step. - -Make sure to remove the OTP logging line in the `generateOTP` method of the Phone Authentication Module Provider's service now that you have integrated Twilio. - -*** - -## Step 4: Use Phone Authentication in the Next.js Starter Storefront - -In this step, you'll customize the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to allow customers to authenticate using their phone number and OTP. - -By default, the Next.js Starter Storefront supports email and password authentication. You'll replace it with phone authentication, but you can also keep both authentication methods if you want to. - -The Next.js Starter Storefront was installed in a separate directory from Medusa. The directory's name is `{your-project}-storefront`. - -So, if your Medusa application's directory is `medusa-phone-auth`, you can find the storefront by going back to the parent directory and changing to the `medusa-phone-auth-storefront` directory: - -```bash -cd ../medusa-phone-auth-storefront # change based on your project name -``` - -### a. Install Phone Input Package - -To easily show a phone input where the user can enter their phone number, install the `react-phone-number-input` package: - -```bash npm2yarn badgeLabel="Storefront" badgeColor="blue" -npm install react-phone-number-input -``` - -You'll use it in the login and registration forms to show a phone input. - -### b. Add Authenticate Function - -Before adding the forms, you'll add the functions that send requests to the Medusa API to authenticate the customer. - -The first one you'll add is the `authenticateWithPhone` function, which sends a request to the `/auth/customer/phone-auth` API route to authenticate the customer using their phone number. - -In `src/lib/data/customer.ts`, add the following function: - -```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" -export const authenticateWithPhone = async (phone: string) => { - try { - const response = await sdk.auth.login("customer", "phone-auth", { - phone, - }) - - if ( - typeof response === "string" || - !response.location || - response.location !== "otp" - ) { - throw new Error("Failed to login") - } - - return true - } catch (error: any) { - return error.toString() - } -} -``` - -The function accepts the phone number as a parameter. - -In the function, you use the [JS SDK](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md), which is configured within the Next.js Starter Storefront, to send a request to the `/auth/customer/phone-auth` API route. You pass the phone number in the request body. - -If the request doesn't return a `location` property set to `otp`, you throw an error. Otherwise, you return `true` to indicate that the request was successful. - -### c. add Verify OTP Function - -Next, you'll add the `verifyOTP` function, which sends a request to the `/auth/customer/phone-auth/callback` API route to verify the OTP. - -In `src/lib/data/customer.ts`, add the following function: - -```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" highlights={verifyOtpHighlights} -export const verifyOtp = async ({ - otp, - phone, -}: { - otp: string - phone: string -}) => { - try { - const token = await sdk.auth.callback("customer", "phone-auth", { - phone, - otp, - }) - - await setAuthToken(token) - - const customerCacheTag = await getCacheTag("customers") - revalidateTag(customerCacheTag) - - await transferCart() - - return true - } catch (e: any) { - return e.toString() - } -} -``` - -The function accepts an object with the following properties: - -- `otp`: The OTP to verify. -- `phone`: The phone number of the customer. - -In the function, you use the JS SDK to send a request to the `/auth/customer/phone-auth/callback` API route. You pass the phone number and OTP in the request body. - -If the request is successful and you receive a token, you set the token in the cookies and refresh the customer cache. This ensures that all customer-related UI is updated after logging in, such as showing the customer's profile when accessing the `/account` page. - -Then, you call the `transferCart` function to transfer the cart from the guest user to the authenticated customer. - -Finally, you return `true` to indicate that the request was successful. - -### d. Add Registration Function - -The last function you'll add is the `registerWithPhone` function, which will register the customer using their phone number. - -In `src/lib/data/customer.ts`, add the following function: - -```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" highlights={registerWithPhoneHighlights} -export const registerWithPhone = async ({ - firstName, - lastName, - phone, -}: { - firstName: string - lastName: string - phone: string -}) => { - try { - const { token: regToken } = await sdk.client.fetch< - { token: string } - >(`/auth/customer/phone-auth/register`, { - method: "POST", - body: { - phone, - }, - }) - - await setAuthToken(regToken as string) - const headers = { - ...(await getAuthHeaders()), - } - - const email = `${phone}@gmail.com` - const customerData = { - email, - first_name: firstName, - last_name: lastName, - phone, - } - - await sdk.store.customer.create( - customerData, - {}, - headers - ) - - return await authenticateWithPhone(phone) - } catch (error: any) { - return error.toString() - } -} -``` - -The function accepts an object with the following properties: - -- `firstName`: The first name of the customer. -- `lastName`: The last name of the customer. -- `phone`: The phone number of the customer. - -In the function, you retrieve a registration token for the customer using the `/auth/customer/phone-auth/register` API route. You pass the phone number in the request body. - -Then, after setting the registration token in the cookies, you create a customer using the [Create Customer](https://docs.medusajs.com/api/store#customers_postcustomers) API route. You pass the following properties in the request body: - -- `email`: The email of the customer. You set it to the phone number with a `@gmail.com` domain. -- `first_name`: The first name of the customer. -- `last_name`: The last name of the customer. -- `phone`: The phone number of the customer. - -Finally, you call the `authenticateWithPhone` function to authenticate the customer using their phone number. At this step, the customer would receive an OTP to login. - -### e. Add OTP Form - -Next, you'll add an OTP form that allows the customer to enter the OTP they receive after login or registration. Later, you'll reuse this form in both the login and registration pages. - -Create the file `src/modules/account/components/otp/index.tsx` with the following content: - -```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={otpHighlights} -"use client" - -import { Input } from "@medusajs/ui" -import { useState, useRef, useEffect } from "react" -import { authenticateWithPhone, verifyOtp } from "../../../../lib/data/customer" -import ErrorMessage from "../../../checkout/components/error-message" - -type Props = { - phone: string -} - -export const Otp = ({ phone }: Props) => { - const [otp, setOtp] = useState("") - const [error, setError] = useState("") - const [isLoading, setIsLoading] = useState(false) - const [countdown, setCountdown] = useState(60) - const inputRefs = useRef<(HTMLInputElement | null)[]>([]) - - const handleSubmit = async () => { - setIsLoading(true) - const response = await verifyOtp({ - otp, - phone, - }) - setOtp("") - setIsLoading(false) - - if (typeof response === "string") { - setError(response) - } - } - - const handleResend = async () => { - authenticateWithPhone(phone) - setCountdown(60) - } - - const handlePaste = (e: React.ClipboardEvent) => { - e.preventDefault() - const pastedData = e.clipboardData.getData("text") - const numericValue = pastedData.replace(/\D/g, "").slice(0, 6) - - if (numericValue) { - setOtp(numericValue) - // Focus the next empty input after pasted content - const nextEmptyIndex = Math.min(numericValue.length, 5) - inputRefs.current[nextEmptyIndex]?.focus() - } - } - - // TODO add use effects -} -``` - -You create an `Otp` component that accepts the phone number as a prop. - -In the component, you define the following state variables: - -- `otp`: The OTP entered by the customer. -- `error`: The error message to show if the OTP verification fails. -- `isLoading`: A boolean indicating whether the OTP verification is in progress. -- `countdown`: The countdown timer for resending the OTP. -- `inputRefs`: A ref to store the input elements for the OTP digits. You'll show six input elements for the OTP digits. - -You also define the following functions: - -- `handleSubmit`: This function is called when the customer submits the OTP. It calls the `verifyOtp` function to verify the OTP entered by the customer. -- `handleResend`: This function is called when the customer clicks the "Resend OTP" button that you'll add later. It calls the `authenticateWithPhone` function to resend the OTP to the customer's phone number. -- `handlePaste`: This function is called when the customer pastes the OTP in the input field. It improves the experience of pasting the OTP without having to enter it manually. - -#### Handle Variable Changes - -Next, you'll add `useEffect` hooks to handle changes in the state variables. - -Replace the `TODO` with the following: - -```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={useEffectHighlights} -useEffect(() => { - if (inputRefs.current[0]) { - inputRefs.current[0].focus() - } -}, [inputRefs.current]) - -useEffect(() => { - if (otp.length !== 6 || isLoading) { - return - } - - handleSubmit() -}, [otp, isLoading]) - -useEffect(() => { - const timer = setInterval(() => { - setCountdown((prev) => { - return prev > 0 ? prev - 1 : 0 - }) - }, 1000) - - return () => clearInterval(timer) -}, []) - -// TODO render form -``` - -You add three `useEffect` hooks: - -1. The first one focuses the first input element when the component mounts. -2. The second one automatically submits the OTP when the customer enters six digits. -3. The third one adds an interval to update the countdown timer every second. - -### f. Render OTP Form - -Lastly, you'll render the OTP form with the input elements and the resend button. - -Replace the `TODO` with the following: - -```tsx title="src/modules/account/components/otp/index.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -

- Verify Phone Number -

-

- Enter the code sent to your phone number to login. -

-
- {[...Array(6)].map((_, index) => ( - { - inputRefs.current[index] = el - }} - onPaste={handlePaste} - value={otp[index] || ""} - onChange={(e) => { - const elm = e.target - const value = elm.value - setOtp((prev) => { - const newOtp = prev.split("") - newOtp[index] = value - return newOtp.join("") - }) - if (value && /^\d+$/.test(value)) { - // Move focus to next input - const nextInput = elm.parentElement?.nextElementSibling?.querySelector("input") - nextInput?.focus() - } - }} - onKeyDown={(e) => { - if (e.key === "Backspace" && !e.currentTarget.value) { - // Move focus to previous input on backspace - const prevInput = e.currentTarget.parentElement?.previousElementSibling?.querySelector("input") - prevInput?.focus() - } - }} - /> - ))} -
-
- -
- -
-) -``` - -You show six input elements for the OTP digits. When a value is entered in an input, the focus moves to the next input. In addition, when the customer presses backspace on an empty input, the focus moves to the previous input. - -You also show a resend button that allows the customer to resend the OTP once the countdown timer reaches zero. - -You now have an OTP form that you can use in both the login and registration pages. - -### g. Add Registration Form - -You'll now add a registration form that allows the customer to register using their phone number. - -First, in `src/modules/account/templates/login-template.tsx`, update the `LOGIN_VIEW` to the following: - -```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={[["4"], ["5"]]} -export enum LOGIN_VIEW { - SIGN_IN = "sign-in", - REGISTER = "register", - REGISTER_PHONE = "register-phone", - SIGN_IN_PHONE = "sign-in-phone", -} -``` - -By default, the login template supports switching between the login and registration views for email and password authentication. With the above change, you add two new views: login and registration with phone number. - -Then, to add the registration form, create the file `src/modules/account/components/register-phone/index.tsx` with the following content: - -```tsx title="src/modules/account/components/register-phone/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={registerPhoneHighlights} -"use client" - -import { useState } from "react" -import Input from "@modules/common/components/input" -import { LOGIN_VIEW } from "@modules/account/templates/login-template" -import ErrorMessage from "@modules/checkout/components/error-message" -import LocalizedClientLink from "@modules/common/components/localized-client-link" -import { registerWithPhone } from "@lib/data/customer" -import "react-phone-number-input/style.css" -import PhoneInput from "react-phone-number-input" -import { Otp } from "../otp" -import { useParams } from "next/navigation" -import { Button } from "@medusajs/ui" - -type Props = { - setCurrentView: (view: LOGIN_VIEW) => void -} - -const RegisterPhone = ({ setCurrentView }: Props) => { - const [firstName, setFirstName] = useState("") - const [lastName, setLastName] = useState("") - const [phone, setPhone] = useState("") - const [error, setError] = useState("") - const [loading, setLoading] = useState(false) - const [enterOtp, setEnterOtp] = useState(false) - const { countryCode } = useParams() as { countryCode: string } - - const handleSubmit = async (e: React.FormEvent) => { - e.preventDefault() - setLoading(true) - const response = await registerWithPhone({ - firstName, - lastName, - phone, - }) - setLoading(false) - if (typeof response === "string") { - setError(response) - return - } - - setEnterOtp(true) - } - - if (enterOtp) { - return - } - - // TODO render form -} - -export default RegisterPhone -``` - -You create a `RegisterPhone` component that accepts a `setCurrentView` prop to switch between the login and registration views. - -In the component, you define the following state variables: - -- `firstName`, `lastName`, and `phone` to store the form inputs' values. -- `error`: The error message to show if the registration fails. -- `loading`: A boolean indicating whether the registration is in progress. -- `enterOtp`: A boolean indicating whether to show the OTP form. This is enabled once the customer is registered and they need to authenticate using the OTP. -- `countryCode`: The country code of the customer, which is retrieved from the URL parameters. You'll use this to show the phone input with a default selected country. - -You also define a `handleSubmit` function that handles the form submission. It calls the `registerWithPhone` function to register the customer using their phone number. - -If the registration is successful, you set `enterOtp` to `true` to show the OTP form. Otherwise, you set the error message. - -#### Render Registration Form - -Next, you'll render the registration form with the input fields and the submit button. - -Replace the `TODO` with the following: - -```tsx title="src/modules/account/components/register-phone/index.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -

You'll use this to show the phone input with a default selected country. - -You also define a `handleSubmit` function that handles the form submission. It calls the `authenticateWithPhone` function to authenticate the customer using their phone number. Then, it enables `enterOtp` to show the OTP form. - -#### Render Login Form - -Next, you'll render the login form with the input field and the submit button. - -Replace the `TODO` with the following: - -```tsx title="src/modules/account/components/login-phone/index.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -

-) -``` - -You render the login form with an input field for the phone number. You also show a submit button that calls the `handleSubmit` function when clicked. - -### i. Add to Login Template - -Next, you'll add the `LoginPhone` component to the login template. - -In `src/modules/account/templates/login-template.tsx`, add the following import: - -```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" -import LoginPhone from "../components/login-phone" -``` - -Next, in the `LoginTemplate` component, change the default value of the `currentView` state to `LOGIN_VIEW.SIGN_IN_PHONE`: - -```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" -const [currentView, setCurrentView] = useState(LOGIN_VIEW.SIGN_IN_PHONE) -``` - -This ensures the phone login form is shown by default. - -Finally, replace the `return` statement of the `LoginTemplate` component to the following: - -```tsx title="src/modules/account/templates/login-template.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -
- {currentView === "sign-in" ? ( - - ) : currentView === "register" ? ( - - ) : currentView === "register-phone" ? ( - - ) : ( - - )} -
-) -``` - -You show the login form when the `currentView` is set to `sign-in-phone`. - -### Test it Out - -You can now test out the phone authentication feature in the Next.js Starter Storefront. - -First, start the Medusa application by running the following command in the Medusa project's directory: - -```bash npm2yarn badgeLabel="Medusa Application" badgeColor="green" -npm run dev -``` - -Then, start the Next.js Starter Storefront by running the following command in the storefront project's directory: - -```bash npm2yarn badgeLabel="Storefront" badgeColor="blue" -npm run dev -``` - -Open your browser, navigate to `http://localhost:8000`, and click on the "Account" link at the top right. This will show the login form with just the phone number input. - -![Login form with phone number input](https://res.cloudinary.com/dza7lstvk/image/upload/v1747739945/Medusa%20Resources/CleanShot_2025-05-20_at_14.18.36_2x_ubuika.png) - -You can also switch to the registration form by clicking on the "Join" link below the login form. - -![Registration form with phone number input](https://res.cloudinary.com/dza7lstvk/image/upload/v1747739988/Medusa%20Resources/CleanShot_2025-05-20_at_14.19.35_2x_btlc2s.png) - -You can try to login with the account you created before, or register with a new one. Once successful, you'll see the OTP form to enter the OTP you received as SMS. - -![OTP form](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740102/Medusa%20Resources/CleanShot_2025-05-20_at_14.21.18_2x_yrkuyg.png) - -After you enter the six digits, you'll be logged in and you'll see your profile page. - -![Profile page](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740166/Medusa%20Resources/CleanShot_2025-05-20_at_14.22.30_2x_kshb83.png) - -*** - -## Step 5: Disallow Phone Updates - -The phone authentication feature is now complete, but there are two improvements you can make: - -1. Show the phone number in the profile page: Currently, it shows the email address, which is a fake address you've set. -2. Disable phone and email updates: Currently, the customer can update their phone number, which is not allowed for phone authentication. - -### a. Show Phone Number in Profile Page - -To show the phone number in the profile page instead of the email, in `src/modules/account/components/overview/index.tsx`, find the following in the `return` statement: - -```tsx title="src/modules/account/components/overview/index.tsx" badgeLabel="Storefront" badgeColor="blue" - - {customer?.email} - -``` - -And replace it with the following: - -```tsx title="src/modules/account/components/overview/index.tsx" badgeLabel="Storefront" badgeColor="blue" - - {customer?.phone} - -``` - -If you check the profile page now, you'll see the phone number instead of the email address at the top right. - -![Phone number showing in profile page](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740378/Medusa%20Resources/CleanShot_2025-05-20_at_14.25.59_2x_x0pxvt.png) - -### b. Remove Email and Phone Fields - -Next, you'll remove the fields to update email and phone number from the profile page. - -In `src/app/[countryCode]/(main)/account/@dashboard/profile/page.tsx`, find the following lines to remove from the `return` statement: - -```tsx title="src/app/[countryCode]/(main)/account/@dashboard/profile/page.tsx" badgeLabel="Storefront" badgeColor="blue" -
- {/* ... */} - {/* Remove the following */} - - - - - {/* ... */} -
-``` - -If you go to your profile page and click on "Profile" in the sidebar, the email and phone number sections will be removed. - -![Profile page without email and phone fields](https://res.cloudinary.com/dza7lstvk/image/upload/v1747740515/Medusa%20Resources/CleanShot_2025-05-20_at_14.28.09_2x_ugab7d.png) - -### c. Disable Phone Updates in Medusa - -While removing the email and phone fields from the profile page prevents customers using the storefront from updating their phone number, it doesn't prevent them from updating it using Medusa's API. - -In this section, you'll add a [middleware](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) to the `/store/customers/me` API route that prevents customers from updating their phone number. - -A middleware is a function that's executed whenever a request is sent to an API route. It's executed before the route handler, allowing you to validate requests, apply authentication guards, and more. - -Learn more in the [Middlewares](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md) documentation. - -To add a middleware in your Medusa application, create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" badgeLabel="Medusa Application" badgeColor="green" -import { defineMiddlewares } from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/customers/me", - method: ["POST"], - middlewares: [ - async (req, res, next) => { - const { phone } = req.body as Record - - if (phone) { - return res.status(400).json({ - error: "Phone number is not allowed to be updated", - }) - } - - next() - }, - ], - }, - ], -}) -``` - -You define middlewares using the `defineMiddlewares` function. It accepts an object having a `routes` property that holds all middlewares applied to API routes. - -Each object in `routes` has the following properties: - -- `matcher`: The API route path to apply the middleware on. You set it to `/store/customers/me`. -- `method`: The HTTP method to apply the middleware to. You set it to `POST` so that the middleware is applied only on `POST` requests sent to the `/store/customers/me` route. -- `middlewares`: An array of middlewares to apply on the route. You add a middleware that throws an error if the request body contains a `phone` property. This prevents customers from updating their phone number using the API. - -Any `POST` request to the `/store/customers/me` route will now be validated to ensure it's not updating the phone number. - -*** - -## Next Steps - -You've now implemented phone authentication in Medusa with Twilio integration. You can further customize the phone authentication feature based on your business use case. - -### Authenticate Other Actor Types - -This tutorial focused on authenticating customers using their phone number. However, you can also authenticate other actor types, such as admin users and vendors. - -To do that, first, enable the `phone-auth` authentication strategy in `medusa-config.ts` for the actor types. For example: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - // ... - http: { - // ... - authMethodsPerActor: { - user: ["emailpass", "phone-auth"], - customer: ["emailpass", "phone-auth"], - vendor: ["emailpass", "phone-auth"], - }, - }, - }, -}) -``` - -Then, when sending requests to the authentication API routes mentioned in the [Test Out Phone Authentication](#test-out-phone-authentication) section, replace `customer` in the API route paths with the actor type you want to authenticate: - -- `/auth/customer/phone-auth/register` -> `/auth/user/phone-auth/register` -- `/auth/customer/phone-auth` -> `/auth/user/phone-auth` -- `/auth/customer/phone-auth/callback` -> `/auth/user/phone-auth/callback` - -Finally, update the UI to show the phone authentication option for the actor type you want to authenticate. This depends on the UI you're using, but you can follow an approach similar to the Next.js Starter Storefront customizations. - -The login form of Medusa Admin can't be customized, so you'll have to build a custom admin dashboard to support phone authentication for admin users. - -### Learn More about Medusa - -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). - -### Troubleshooting - -If you encounter issues during your development, check out the [troubleshooting guides](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/troubleshooting/index.html.md). - -### Getting Help - -If you encounter issues not covered in the troubleshooting guides: - -1.

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

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/infrastructure-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/infrastructure-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/docs/learn/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.

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.

If you don't have an account, create one [here](https://www.shipstation.com/start-a-free-trial). + +### Enable Carriers + +To create labels for your shipments, you need to enable carriers. This requires you to enter payment and address details. + +To enable carriers: + +1. On the Onboard page, in the "Enable carriers & see rates" section, click on the "Enable Carriers" button. + +![Scroll down to the Enable carriers & see rates section, and find the "Enable Carriers" button.](https://res.cloudinary.com/dza7lstvk/image/upload/v1734523873/Medusa%20Resources/Screenshot_2024-12-18_at_2.10.54_PM_pmvcfr.png) + +2.

Find Shipping API and activate it. + +You'll later retrieve your API key. + +*** + +## Step 3: Create ShipStation 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 Fulfillment Module delegates processing fulfillments and shipments to other modules, called module providers. In this step, you'll create a ShipStation Module Provider that implements all functionalities required for fulfillment. In later steps, you'll add into Medusa shipping options for ShipStation, and allow customers to choose it during checkout. + +Learn more about modules in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). + +### Create Module Directory + +A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/shipstation`. + +![The directory structure of the Medusa application after adding the module's directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1734338950/Medusa%20Resources/shipstation-dir-overview-1_dlsrbv.jpg) + +### Create Service + +You define a module's functionalities in a service. A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, which is useful if your module defines tables in the database, or connect to a third-party service. + +In this section, you'll create the ShipStation Module Provider's service and the methods necessary to handle fulfillment. + +Start by creating the file `src/modules/shipstation/service.ts` with the following content: + +![The directory structure of the Medusa application after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339042/Medusa%20Resources/shipstation-dir-overview-2_cmgvcj.jpg) + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights1} +import { AbstractFulfillmentProviderService } from "@medusajs/framework/utils" + +export type ShipStationOptions = { + api_key: string +} + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + static identifier = "shipstation" + protected options_: ShipStationOptions + + constructor({}, options: ShipStationOptions) { + super() + + this.options_ = options + } + + // TODO add methods +} + +export default ShipStationProviderService +``` + +A Fulfillment Module Provider service must extend the `AbstractFulfillmentProviderService` class. You'll implement the abstract methods of this class in the upcoming sections. + +The service must have an `identifier` static property, which is a unique identifier for the provider. You set the identifier to `shipstation`. + +A module can receive options that are set when you later add the module to Medusa's configurations. These options allow you to safely store secret values outside of your code. + +The ShipStation module requires an `api_key` option, indicating your ShipStation's API key. You receive the options as a second parameter of the service's constructor. + +### Create Client + +To send requests to ShipStation, you'll create a client class that provides the methods to send requests. You'll then use that class in your service. + +Create the file `src/modules/shipstation/client.ts` with the following content: + +![The directory structure of the Medusa application after adding the client file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339519/Medusa%20Resources/shipstation-dir-overview-3_b8im2d.jpg) + +```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights1} +import { ShipStationOptions } from "./service" +import { MedusaError } from "@medusajs/framework/utils" + +export class ShipStationClient { + options: ShipStationOptions + + constructor(options) { + this.options = options + } + + private async sendRequest(url: string, data?: RequestInit): Promise { + return fetch(`https://api.shipstation.com/v2${url}`, { + ...data, + headers: { + ...data?.headers, + "api-key": this.options.api_key, + "Content-Type": "application/json", + }, + }).then((resp) => { + const contentType = resp.headers.get("content-type") + if (!contentType?.includes("application/json")) { + return resp.text() + } + + return resp.json() + }) + .then((resp) => { + if (typeof resp !== "string" && resp.errors?.length) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `An error occured while sending a request to ShipStation: ${ + resp.errors.map((error) => error.message) + }` + ) + } + + return resp + }) + } +} +``` + +The `ShipStationClient` class accepts the ShipStation options in its constructor and sets those options in the `options` property. + +You also add a private `sendRequest` method that accepts a path to send a request to and the request's configurations. In the method, you send a request using the Fetch API, passing the API key from the options in the request header. You also parse the response body based on its content type, and check if there are any errors to be thrown before returning the parsed response. + +You'll add more methods to send requests in the upcoming steps. + +To use the client in `ShipStationProviderService`, add it as a class property and initialize it in the constructor: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights2} +// imports... +import { ShipStationClient } from "./client" + +// ... + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // properties... + protected client: ShipStationClient + + constructor({}, options: ShipStationOptions) { + // ... + this.client = new ShipStationClient(options) + } +} +``` + +You import `ShipStationClient` and add a new `client` property in `ShipStationProviderService`. In the class's constructor, you set the `client` property by initializing `ShipStationProviderService`, passing it the module's options. + +You'll use the `client` property when implementing the service's methods. + +### Implement Service Methods + +In this section, you'll go back to the `ShipStationProviderService` method to implement the abstract methods of `AbstractFulfillmentProviderService`. + +Refer to [this guide](https://docs.medusajs.com/references/fulfillment/provider/index.html.md) for a full reference of all methods, their parameters and return types. + +#### getFulfillmentOptions + +The `getFulfillmentOptions` method returns the options that this fulfillment provider supports. When admin users add shipping options later in the Medusa Admin, they'll select one of these options. + +Learn more about shipping options in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). + +ShipStation requires that a shipment must be associated with a carrier and one of its services. So, in this method, you'll retrieve the list of carriers from ShipStation and return them as fulfillment options. Shipping options created from these fulfillment options will always have access to the option's carrier and service. + +Before you start implementing methods, you'll add the expected carrier types returned by ShipStation. Create the file `src/modules/shipstation/types.ts` with the following content: + +![The directory structure of the Medusa application after adding the types file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734340402/Medusa%20Resources/shipstation-dir-overview-4_fwsle0.jpg) + +```ts title="src/modules/shipstation/types.ts" +export type Carrier = { + carrier_id: string + disabled_by_billing_plan: boolean + friendly_name: string + services: { + service_code: string + name: string + }[] + packages: { + package_code: string + }[] + [k: string]: unknown +} + +export type CarriersResponse = { + carriers: Carrier[] +} +``` + +You define a `Carrier` type that holds a carrier's details, and a `CarriersResponse` type, which is the response returned by ShipStation. + +A carrier has more fields that you can use. Refer to [ShipStation's documentation](https://docs.shipstation.com/openapi/carriers/list_carriers#carriers/list_carriers/t=response\&c=200\&path=carriers) for all carrier fields. + +Next, you'll add in `ShipStationClient` the method to retrieve the carriers from ShipStation. So, add to the class defined in `src/modules/shipstation/client.ts` a new method: + +```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights2} +// other imports... +import { + CarriersResponse, +} from "./types" + +export class ShipStationClient { + // ... + async getCarriers(): Promise { + return await this.sendRequest("/carriers") + } +} +``` + +You added a new `getCarriers` method that uses the `sendRequest` method to send a request to the [ShipStation's List Carriers endpoint](https://docs.shipstation.com/openapi/carriers/list_carriers). The method returns `CarriersResponse` that you defined earlier. + +Finally, add the `getFulfillmentOptions` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights3} +// other imports... +import { + FulfillmentOption, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async getFulfillmentOptions(): Promise { + const { carriers } = await this.client.getCarriers() + const fulfillmentOptions: FulfillmentOption[] = [] + + carriers + .filter((carrier) => !carrier.disabled_by_billing_plan) + .forEach((carrier) => { + carrier.services.forEach((service) => { + fulfillmentOptions.push({ + id: `${carrier.carrier_id}__${service.service_code}`, + name: service.name, + carrier_id: carrier.carrier_id, + carrier_service_code: service.service_code, + }) + }) + }) + + return fulfillmentOptions + } +} +``` + +In the `getFulfillmentOptions` method, you retrieve the carriers from ShipStation. You then filter out the carriers disabled by your ShipStation billing plan, and loop over the remaining carriers and their services. + +You return an array of fulfillment-option objects, where each object represents a carrier and service pairing. Each object has the following properties: + +- an `id` property, which you set to a combination of the carrier ID and the service code. +- a `name` property, which you set to the service's `name`. The admin user will see this name when they create a shipping option for the ShipStation provider. +- You can pass other data, such as `carrier_id` and `carrier_service_code`, and Medusa will store the fulfillment option in the `data` property of shipping options created later. + +Learn more about the shipping option's `data` property in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). + +You'll see this method in action later when you create a shipping option. + +#### canCalculate + +When an admin user creates a shipping option for your provider, they can choose whether the price is flat rate or calculated during checkout. + +If the user chooses calculated, Medusa validates that your fulfillment provider supports calculated prices using the `canCalculate` method of your provider's service. + +This method accepts the shipping option's `data` field, which will hold the data of an option returned by `getFulfillmentOptions`. It returns a boolean value indicating whether the shipping option can have a calculated price. + +Add the method to `ShipStationProviderService` in `src/modules/shipstation/service.ts`: + +```ts title="src/modules/shipstation/service.ts" +// other imports... +import { + // ... + CreateShippingOptionDTO, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async canCalculate(data: CreateShippingOptionDTO): Promise { + return true + } +} +``` + +Since all shipping option prices can be calculated with ShipStation based on the chosen carrier and service zone, you always return `true` in this method. + +You'll implement the calculation mechanism in a later method. + +#### calculatePrice + +When the customer views available shipping options during checkout, the Medusa application requests the calculated price from your fulfillment provider using its `calculatePrice` method. + +To retrieve shipping prices with ShipStation, you create a shipment first then get its rates. So, in the `calculatePrice` method, you'll either: + +- Send a request to [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates) that creates a shipment and returns its prices; +- Or, if a shipment was already created before, you'll retrieve its prices using [ShipStation's get shipment rates endpoint](https://docs.shipstation.com/openapi/shipments/list_shipment_rates). + +First, add the following types to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" highlights={typesHighlights1} +export type ShipStationAddress = { + name: string + phone: string + email?: string | null + company_name?: string | null + address_line1: string + address_line2?: string | null + address_line3?: string | null + city_locality: string + state_province: string + postal_code: string + country_code: string + address_residential_indicator: "unknown" | "yes" | "no" + instructions?: string | null + geolocation?: { + type?: string + value?: string + }[] +} + +export type Rate = { + rate_id: string + shipping_amount: { + currency: string + amount: number + } + insurance_amount: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + other_amount: { + currency: string + amount: number + } + tax_amount: { + currency: string + amount: number + } +} + +export type RateResponse = { + rates: Rate[] +} + +export type GetShippingRatesRequest = { + shipment_id?: string + shipment?: Omit + rate_options: { + carrier_ids: string[] + service_codes: string[] + preferred_currency: string + } +} + +export type GetShippingRatesResponse = { + shipment_id: string + carrier_id?: string + service_code?: string + external_order_id?: string + rate_response: RateResponse +} + +export type Shipment = { + shipment_id: string + carrier_id: string + service_code: string + ship_to: ShipStationAddress + return_to?: ShipStationAddress + is_return?: boolean + ship_from: ShipStationAddress + items?: [ + { + name?: string + quantity?: number + sku?: string + } + ] + warehouse_id?: string + shipment_status: "pending" | "processing" | "label_purchased" | "cancelled" + [k: string]: unknown +} + +``` + +You add the following types: + +- `ShipStationAddress`: an address to ship from or to. +- `Rate`: a price rate for a specified carrier and service zone. +- `RateResponse`: The response when retrieving rates. +- `GetShippingRatesRequest`: The request body data for [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates).

ShipStation requires the addresses to ship the items from and to. + +To send the request, replace the `TODO` with the following: + +```ts title="src/modules/shipstation/service.ts" +// Sum the package's weight +// You can instead create different packages for each item +const packageWeight = items.reduce((sum, item) => { + // @ts-ignore + return sum + (item.variant.weight || 0) +}, 0) + +return await this.client.getShippingRates({ + shipment: { + carrier_id: carrier_id, + service_code: carrier_service_code, + ship_to, + ship_from, + validate_address: "no_validation", + items: items?.map((item) => ({ + name: item.title, + quantity: item.quantity, + sku: item.variant_sku || "", + })), + packages: [{ + weight: { + value: packageWeight, + unit: "kilogram", + }, + }], + customs: { + contents: "merchandise", + non_delivery: "return_to_sender", + }, + }, + rate_options: { + carrier_ids: [carrier_id], + service_codes: [carrier_service_code], + preferred_currency: currency_code as string, + }, +}) +``` + +You create a shipment and get its rates using the `getShippingRates` method you added to the client. You pass the method the expected request body parameters by [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates), including the carrier ID, the items to be shipped, and more. + +The above snippet assumes all items are sent in a single package. You can instead pass a package for each item, specifying its weight and optionally its height, width, and length. + +Finally, add the `calculatePrice` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights5} +// other imports... +import { + // ... + CalculatedShippingOptionPrice, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async calculatePrice( + optionData: CalculateShippingOptionPriceDTO["optionData"], + data: CalculateShippingOptionPriceDTO["data"], + context: CalculateShippingOptionPriceDTO["context"] + ): Promise { + const { shipment_id } = data as { + shipment_id?: string + } || {} + const { carrier_id, carrier_service_code } = optionData as { + carrier_id: string + carrier_service_code: string + } + let rate: Rate | undefined + + if (!shipment_id) { + const shipment = await this.createShipment({ + carrier_id, + carrier_service_code, + from_address: { + name: context.from_location?.name, + address: context.from_location?.address, + }, + to_address: context.shipping_address, + items: context.items || [], + currency_code: context.currency_code as string, + }) + rate = shipment.rate_response.rates[0] + } else { + const rateResponse = await this.client.getShipmentRates(shipment_id) + rate = rateResponse[0].rates[0] + } + + const calculatedPrice = !rate ? 0 : rate.shipping_amount.amount + rate.insurance_amount.amount + + rate.confirmation_amount.amount + rate.other_amount.amount + + (rate.tax_amount?.amount || 0) + + return { + calculated_amount: calculatedPrice, + is_calculated_price_tax_inclusive: !!rate?.tax_amount, + } + } +} +``` + +The `calculatePrice` method accepts the following parameters: + +1. The `data` property of the chosen shipping option during checkout. +2. The `data` property of the shipping method, which will hold the ID of the shipment in ShipStation. +3. An object of the checkout's context, including the cart's items, the location associated with the shipping option, and more. + +In the method, you first check if a `shipment_id` is already stored in the shipping method's `data` property. If so, you retrieve the shipment's rates using the client's `getShipmentRates` method. Otherwise, you use the `createShipment` method to create the shipment and get its rates. + +A rate returned by ShipStation has four properties that, when added up, make up the full price: `shipping_amount`, `insurance_amount`, `confirmation_amount`, and `other_amount`. It may have a `tax_amount` property, which is the amount for applied taxes. + +Learn more about these fields in [ShipStation's documentation](https://docs.shipstation.com/rate-shopping#about-the-response). + +The method returns an object having the following properties: + +- `calculated_amount`: The shipping method's price calculated by adding the four rate properties with the tax property, if available. +- `is_calculated_price_tax_inclusive`: Whether the price includes taxes, which is inferred from whether the `tax_amount` property is set in the rate. + +Customers will now see the calculated price of a ShipStation shipping option during checkout. + +#### validateFulfillmentData + +When a customer chooses a shipping option during checkout, Medusa creates a shipping method from that option. A shipping method has a `data` property to store data relevant for later processing of the method and its fulfillments. + +So, in the `validateFulfillmentData` method of your provider, you'll create a shipment in ShipStation if it wasn't already created using their [get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates), and store the ID of that shipment in the created shipping method's `data` property. + +Add the `validateFulfillmentData` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights4} +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async validateFulfillmentData( + optionData: Record, + data: Record, + context: Record + ): Promise { + let { shipment_id } = data as { + shipment_id?: string + } + + if (!shipment_id) { + const { carrier_id, carrier_service_code } = optionData as { + carrier_id: string + carrier_service_code: string + } + const shipment = await this.createShipment({ + carrier_id, + carrier_service_code, + from_address: { + // @ts-ignore + name: context.from_location?.name, + // @ts-ignore + address: context.from_location?.address, + }, + // @ts-ignore + to_address: context.shipping_address, + // @ts-ignore + items: context.items || [], + // @ts-ignore + currency_code: context.currency_code, + }) + shipment_id = shipment.shipment_id + } + + return { + ...data, + shipment_id, + } + } +} +``` + +The `validateFulfillmentData` method accepts the following parameters: + +1. The `data` property of the chosen shipping option during checkout. It will hold the carrier ID and its service code. +2. The `data` property of the shipping method to be created. This can hold custom data sent in the [Add Shipping Method API route](https://docs.medusajs.com/api/store#carts_postcartsidshippingmethods). +3. An object of the checkout's context, including the cart's items, the location associated with the shipping option, and more. + +In the method, you try to retrieve the shipment ID from the shipping method's `data` parameter if it was already created. If not, you create the shipment in ShipStation using the `createShipment` method. + +Finally, you return the object to be stored in the shipping method's `data` property. You include in it the ID of the shipment in ShipStation. + +#### createFulfillment + +After the customer places the order, the admin user can manage its fulfillments. When the admin user creates a fulfillment for the order, Medusa uses the `createFulfillment` method of the associated provider to handle any processing in the third-party provider. + +This method supports creating split fulfillments, meaning you can partially fulfill and order's items. So, you'll create a new shipment, then purchase a label for that shipment. You'll use the existing shipment to retrieve details like the address to ship from and to. + +First, add a new type to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" +export type Label = { + label_id: string + status: "processing" | "completed" | "error" | "voided" + shipment_id: string + ship_date: Date + shipment_cost: { + currency: string + amount: number + } + insurance_cost: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + tracking_number: string + is_return_label: boolean + carrier_id: string + service_code: string + trackable: string + tracking_status: "unknown" | "in_transit" | "error" | "delivered" + label_download: { + href: string + pdf: string + png: string + zpl: string + } +} +``` + +You add the `Label` type for the details in a label object. You can find more properties in [ShipStation's documentation](https://docs.shipstation.com/openapi/labels/create_label#labels/create_label/response\&c=200/body). + +Then, add the following methods to the `ShipStationClient`: + +```ts title="src/modules/shipstation/client.ts" +// other imports... +import { + // ... + Label, + Shipment, +} from "./types" + +export class ShipStationClient { + // ... + + async getShipment(id: string): Promise { + return await this.sendRequest(`/shipments/${id}`) + } + + async purchaseLabelForShipment(id: string): Promise
