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.

Your efforts are only spent on implementing the functionality performed by the job, such as syncing products to an ERP. + +- You want the action to execute at a specified schedule while the Medusa application **isn't** running. Instead, use the operating system's equivalent of a cron job. +- You want to execute the action once when the application loads. Use [loaders](https://docs.medusajs.com/learn/fundamentals/modules/loaders/index.html.md) instead. +- You want to execute the action if an event occurs. Use [subscribers](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) instead. + +*** + +## How to Create a Scheduled Job? + +You create a scheduled job in a TypeScript or JavaScript file under the `src/jobs` directory. The file exports the asynchronous function to run, and the configurations indicating the schedule to run the function. + +For example, create the file `src/jobs/hello-world.ts` with the following content: + +![Example of scheduled job file in the application's directory structure](https://res.cloudinary.com/dza7lstvk/image/upload/v1732866423/Medusa%20Book/scheduled-job-dir-overview_ediqgm.jpg) + +```ts title="src/jobs/hello-world.ts" highlights={highlights} +import { MedusaContainer } from "@medusajs/framework/types" + +export default async function greetingJob(container: MedusaContainer) { + const logger = container.resolve("logger") + + logger.info("Greeting!") +} + +export const config = { + name: "greeting-every-minute", + schedule: "* * * * *", +} +``` + +You export an asynchronous function that receives the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) as a parameter. In the function, you resolve the [Logger utility](https://docs.medusajs.com/learn/debugging-and-testing/logging/index.html.md) from the Medusa container and log a message. + +You also export a `config` object that has the following properties: + +- `name`: A unique name for the job. +- `schedule`: A string that holds a [cron expression](https://crontab.guru/) indicating the schedule to run the job. + +This scheduled job executes every minute and logs into the terminal `Greeting!`. + +### Test the Scheduled Job + +To test out your scheduled job, start the Medusa application: + +```bash npm2yarn +npm run dev +``` + +After a minute, the following message will be logged to the terminal: + +```bash +info: Greeting! +``` + +*** + +## Example: Sync Products Once a Day + +In this section, you'll find a brief example of how you use a scheduled job to sync products to a third-party service. + +When implementing flows spanning across systems or [modules](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md), you use [workflows](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). A workflow is a task made up of a series of steps, and you construct it like you would a regular function, but it's a special function that supports rollback mechanism in case of errors, background execution, and more. + +You can learn how to create a workflow in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md), but this example assumes you already have a `syncProductToErpWorkflow` implemented. To execute this workflow once a day, create a scheduled job at `src/jobs/sync-products.ts` with the following content: + +```ts title="src/jobs/sync-products.ts" +import { MedusaContainer } from "@medusajs/framework/types" +import { syncProductToErpWorkflow } from "../workflows/sync-products-to-erp" + +export default async function syncProductsJob(container: MedusaContainer) { + await syncProductToErpWorkflow(container) + .run() +} + +export const config = { + name: "sync-products-job", + schedule: "0 0 * * *", +} +``` + +In the scheduled job function, you execute the `syncProductToErpWorkflow` by invoking it and passing it the container, then invoking the `run` method. You also specify in the exported configurations the schedule `0 0 * * *` which indicates midnight time of every day. + +The next time you start the Medusa application, it will run this job every day at midnight. + + +# Medusa's Architecture + +In this chapter, you'll learn about the architectural layers in Medusa. + +Find the full architectural diagram at the [end of this chapter](#full-diagram-of-medusas-architecture). + +## HTTP, Workflow, and Module Layers + +Medusa is a headless commerce platform.

However, you may need to associate data models of different modules, or you're trying to extend data models from Commerce Modules with custom properties. To do that, you define module links. + +A module link forms an association between two data models of different modules while maintaining module isolation. You can then manage and query linked records of the data models using Medusa's Modules SDK. + +In this chapter, you'll define a module link between the `Brand` data model of the Brand Module, and the `Product` data model of the Product Module.

Each module object has a special `linkable` property that holds the data models' link configurations. + +The `defineLink` function accepts two parameters of the same type, which is either: + +- The data model's link configuration, which you access from the Module's `linkable` property; +- Or an object that has two properties: + - `linkable`: the data model's link configuration, which you access from the Module's `linkable` property. + - `isList`: A boolean indicating whether many records of the data model can be linked to the other model. + +So, in the above code snippet, you define a link between the `Product` and `Brand` data models. Since a brand can be associated with multiple products, you enable `isList` in the `Product` model's object. + +*** + +## 2. Sync the Link to the Database + +A module link is represented in the database as a table that stores the IDs of linked records.

The workflow has the following steps: +This consumes the `productsCreated` hook, which runs after the products are created. -- `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. +If `brand` is passed in `additional_data`, you resolve the Product Module's main service and use its `upsertProducts` method to update the products, adding the brand to the `metadata` property. -You'll execute this workflow in the subscriber next. +### Compensation Function -Learn more about `useQueryGraphStep` in [this reference](https://docs.medusajs.com/resources/references/helper-steps/useQueryGraphStep/index.html.md). +Hooks also accept a compensation function as a second parameter to undo the actions made by the step function. + +For example, pass the following second parameter to the `productsCreated` hook: + +```ts title="src/workflows/hooks/product-created.ts" +createProductsWorkflow.hooks.productsCreated( + async ({ products, additional_data }, { container }) => { + // ... + }, + async ({ products, additional_data }, { container }) => { + if (!additional_data.brand) { + return + } + + const productModuleService = container.resolve( + Modules.PRODUCT + ) + + await productModuleService.upsertProducts( + products + ) + } +) +``` + +This updates the products to their original state before adding the brand to their `metadata` property. + + +# Handling CORS in API Routes + +In this chapter, you’ll learn about the CORS middleware and how to configure it for custom API routes. + +## CORS Overview + +Cross-Origin Resource Sharing (CORS) allows only configured origins to access your API Routes. + +For example, if you allow only origins starting with `http://localhost:7001` to access your Admin API Routes, other origins accessing those routes get a CORS error. + +### CORS Configurations + +The `storeCors` and `adminCors` properties of Medusa's `http` configuration set the allowed origins for routes starting with `/store` and `/admin` respectively. + +These configurations accept a URL pattern to identify allowed origins. + +For example: + +```js title="medusa-config.ts" +module.exports = defineConfig({ + projectConfig: { + http: { + storeCors: "http://localhost:8000", + adminCors: "http://localhost:7001", + // ... + }, + }, +}) +``` + +This allows the `http://localhost:7001` origin to access the Admin API Routes, and the `http://localhost:8000` origin to access Store API Routes. + +Learn more about the CORS configurations in [this resource guide](https://docs.medusajs.com/learn/configurations/medusa-config#http/index.html.md). *** -## 3. Handle brand.created Event +## CORS in Store and Admin Routes -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. +To disable the CORS middleware for a route, export a `CORS` variable in the route file with its value set to `false`. -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: +For example: -![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/api/store/custom/route.ts" highlights={[["15"]]} +import type { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" -```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 GET = ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: "[GET] Hello world!", }) } -export const config: SubscriberConfig = { - event: "brand.created", -} +export const CORS = false ``` -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). +This disables the CORS middleware on API Routes at the path `/store/custom`. *** -## Test it Out +## CORS in Custom Routes -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. +If you create a route that doesn’t start with `/store` or `/admin`, you must apply the CORS middleware manually. Otherwise, all requests to your API route lead to a CORS error. -First, start the Medusa application: +You can do that in the exported middlewares configurations in `src/api/middlewares.ts`. + +For example: + +```ts title="src/api/middlewares.ts" highlights={highlights} collapsibleLines="1-10" expandButtonLabel="Show Imports" +import { defineMiddlewares } from "@medusajs/framework/http" +import type { + MedusaNextFunction, + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { ConfigModule } from "@medusajs/framework/types" +import { parseCorsOrigins } from "@medusajs/framework/utils" +import cors from "cors" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom*", + middlewares: [ + ( + req: MedusaRequest, + res: MedusaResponse, + next: MedusaNextFunction + ) => { + const configModule: ConfigModule = + req.scope.resolve("configModule") + + return cors({ + origin: parseCorsOrigins( + configModule.projectConfig.http.storeCors + ), + credentials: true, + })(req, res, next) + }, + ], + }, + ], +}) +``` + +This retrieves the configurations exported from `medusa-config.ts` and applies the `storeCors` to routes starting with `/custom`. + + +# Middlewares + +In this chapter, you’ll learn about middlewares and how to create them. + +## What is a Middleware? + +A middleware is a function executed when a request is sent to an API Route. It's executed before the route handler function. + +Middlewares are used to guard API routes, parse request content types other than `application/json`, manipulate request data, and more. + +As Medusa's server is based on Express, you can use any [Express middleware](https://expressjs.com/en/resources/middleware.html). + +### Middleware Types + +There are two types of middlewares: + +1. Global Middleware: A middleware that applies to all routes matching a specified pattern. +2. Route Middleware: A middleware that applies to routes matching a specified pattern and HTTP method(s). + +These middlewares generally have the same definition and usage, but they differ in the routes they apply to. You'll learn how to create both types in the following sections. + +*** + +## How to Create a Global Middleware? + +Middlewares of all types are defined in the special file `src/api/middlewares.ts`. Use the `defineMiddlewares` function from the Medusa Framework to define the middlewares, and export its value. + +For example: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + MedusaNextFunction, + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom*", + middlewares: [ + ( + req: MedusaRequest, + res: MedusaResponse, + next: MedusaNextFunction + ) => { + console.log("Received a request!") + + next() + }, + ], + }, + ], +}) +``` + +The `defineMiddlewares` function accepts a middleware configurations object that has the property `routes`. `routes`'s value is an array of middleware route objects, each having the following properties: + +- `matcher`: a string or regular expression indicating the API route path to apply the middleware on. The regular expression must be compatible with [path-to-regexp](https://github.com/pillarjs/path-to-regexp). +- `middlewares`: An array of global and route middleware functions. + +In the example above, you define a global middleware that logs the message `Received a request!` whenever a request is sent to an API route path starting with `/custom`. + +### Test the Global Middleware + +To test the middleware: + +1. Start the 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: +2. Send a request to any API route starting with `/custom`. +3. See the following message in the terminal: ```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" +Received a request! ``` *** -## Next Chapter: Sync Brand from Third-Party CMS to Medusa +## How to Create a Route Middleware? -You can also automate syncing data from a third-party system to Medusa at a regular interval. In the next chapter, you'll learn how to sync brands from the third-party CMS to Medusa once a day. +In the previous section, you learned how to create a global middleware. You define the route middleware in the same way in `src/api/middlewares.ts`, but you specify an additional property `method` in the middleware route object. Its value is one or more HTTP methods to apply the middleware to. +For example: -# Guide: Query Product's Brands +```ts title="src/api/middlewares.ts" highlights={highlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + MedusaNextFunction, + MedusaRequest, + MedusaResponse, + defineMiddlewares, +} from "@medusajs/framework/http" -In the previous chapters, you [defined a link](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md) between the [custom Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) and Medusa's [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md), then [extended the create-product flow](https://docs.medusajs.com/learn/customization/extend-features/extend-create-product/index.html.md) to link a product to a brand. +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom*", + method: ["POST", "PUT"], + middlewares: [ + ( + req: MedusaRequest, + res: MedusaResponse, + next: MedusaNextFunction + ) => { + console.log("Received a request!") -In this chapter, you'll learn how to retrieve a product's brand (and vice-versa) in two ways: Using Medusa's existing API route, or in customizations, such as a custom API route. + next() + }, + ], + }, + ], +}) +``` -### Prerequisites +This example applies the middleware only when a `POST` or `PUT` request is sent to an API route path starting with `/custom`, changing the middleware from a global middleware to a route middleware. -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) -- [Defined link between the Brand and Product data models.](https://docs.medusajs.com/learn/customization/extend-features/define-link/index.html.md) +### Test the Route Middleware -*** +To test the middleware: -## Approach 1: Retrieve Brands in Existing API Routes +1. Start the application: -Medusa's existing API routes accept a `fields` query parameter that allows you to specify the fields and relations of a model to retrieve. So, when you send a request to the [List Products](https://docs.medusajs.com/api/admin#products_getproducts), [Get Product](https://docs.medusajs.com/api/admin#products_getproductsid), or any product-related store or admin routes that accept a `fields` query parameter, you can specify in this parameter to return the product's brands. +```bash npm2yarn +npm run dev +``` -Learn more about using the `fields` query parameter to retrieve custom linked data models in the [Retrieve Custom Linked Data Models from Medusa's API Routes](https://docs.medusajs.com/learn/fundamentals/api-routes/retrieve-custom-links/index.html.md) chapter. - -For example, send the following request to retrieve the list of products with their brands: +2. Send a `POST` request to any API route starting with `/custom`. +3. See the following message in the terminal: ```bash -curl 'http://localhost:9000/admin/products?fields=+brand.*' \ ---header 'Authorization: Bearer {token}' +Received a request! ``` -Make sure to replace `{token}` with your admin user's authentication token. Learn how to retrieve it in the [API reference](https://docs.medusajs.com/api/store#authentication). - -Any product that is linked to a brand will have a `brand` property in its object: - -```json title="Example Product Object" -{ - "id": "prod_123", - // ... - "brand": { - "id": "01JEB44M61BRM3ARM2RRMK7GJF", - "name": "Acme", - "created_at": "2024-12-05T09:59:08.737Z", - "updated_at": "2024-12-05T09:59:08.737Z", - "deleted_at": null - } -} -``` - -By using the `fields` query parameter, you don't have to re-create existing API routes to get custom data models that you linked to core data models. - -### Limitations: Filtering by Brands in Existing API Routes - -While you can retrieve linked records using the `fields` query parameter of an existing API route, you can't filter by linked records. - -Instead, you'll have to create a custom API route that uses Query to retrieve linked records with filters, as explained in the [Query documentation](https://docs.medusajs.com/learn/fundamentals/module-links/query#apply-filters-and-pagination-on-linked-records/index.html.md). - *** -## Approach 2: Use Query to Retrieve Linked Records +## When to Use Middlewares -You can also retrieve linked records using Query. Query allows you to retrieve data across modules with filters, pagination, and more. You can resolve Query from the Medusa container and use it in your API route or workflow. +- You want to protect API routes by a custom condition. +- You're modifying the request body. -Learn more about Query in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). +*** -For example, you can create an API route that retrieves brands and their products. If you followed the [Create Brands API route chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll have the file `src/api/admin/brands/route.ts` with a `POST` API route. Add a new `GET` function to the same file: +## Middleware Function Parameters -```ts title="src/api/admin/brands/route.ts" highlights={highlights} -// other imports... -import { +The middleware function accepts three parameters: + +1. A request object of type `MedusaRequest`. +2. A response object of type `MedusaResponse`. +3. A function of type `MedusaNextFunction` that executes the next middleware in the stack. + +You must call the `next` function in the middleware. Otherwise, other middlewares and the API route handler won’t execute. + +*** + +## Middleware for Routes with Path Parameters + +To indicate a path parameter in a middleware's `matcher` pattern, use the format `:{param-name}`. + +For example: + +```ts title="src/api/middlewares.ts" collapsibleLines="1-7" expandMoreLabel="Show Imports" highlights={pathParamHighlights} +import { + MedusaNextFunction, + MedusaRequest, + MedusaResponse, + defineMiddlewares, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom/:id", + middlewares: [ + // ... + ], + }, + ], +}) +``` + +This applies a middleware to the routes defined in the file `src/api/custom/[id]/route.ts`. + +*** + +## Request URLs with Trailing Backslashes + +A middleware whose `matcher` pattern doesn't end with a backslash won't be applied for requests to URLs with a trailing backslash. + +For example, consider you have the following middleware: + +```ts title="src/api/middlewares.ts" collapsibleLines="1-7" expandMoreLabel="Show Imports" +import { + MedusaNextFunction, + MedusaRequest, + MedusaResponse, + defineMiddlewares, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom", + middlewares: [ + ( + req: MedusaRequest, + res: MedusaResponse, + next: MedusaNextFunction + ) => { + console.log("Received a request!") + + next() + }, + ], + }, + ], +}) +``` + +If you send a request to `http://localhost:9000/custom`, the middleware will run. + +However, if you send a request to `http://localhost:9000/custom/`, the middleware won't run. + +In general, avoid adding trailing backslashes when sending requests to API routes. + +*** + +## Middlewares and Route Ordering + +The ordering explained in this section was added in [Medusa v2.6](https://github.com/medusajs/medusa/releases/tag/v2.6) + +The Medusa application registers middlewares and API route handlers in the following order: + +1. Global middlewares in the following order: + 1. Global middleware defined in the Medusa's core. + 2. Global middleware defined in the plugins (in the order the plugins are registered in). + 3. Global middleware you define in the application. +2. Route middlewares in the following order: + 1. Route middleware defined in the Medusa's core. + 2. Route middleware defined in the plugins (in the order the plugins are registered in). + 3. Route middleware you define in the application. +3. API routes in the following order: + 1. API routes defined in the Medusa's core. + 2. API routes defined in the plugins (in the order the plugins are registered in). + 3. API routes you define in the application. + +### Middlewares Sorting + +On top of the previous ordering, Medusa sorts global and route middlewares based on their matcher pattern in the following order: + +1. Wildcard matchers. For example, `/custom*`. +2. Regex matchers. For example, `/custom/(products|collections)`. +3. Static matchers without parameters. For example, `/custom`. +4. Static matchers with parameters. For example, `/custom/:id`. + +For example, if you have the following middlewares: + +```ts title="src/api/middlewares.ts" +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom/:id", + middlewares: [/* ... */], + }, + { + matcher: "/custom", + middlewares: [/* ... */], + }, + { + matcher: "/custom*", + method: ["GET"], + middlewares: [/* ... */], + }, + { + matcher: "/custom/:id", + method: ["GET"], + middlewares: [/* ... */], + }, + ], +}) +``` + +The global middlewares are sorted into the following order before they're registered: + +1. Global middleware `/custom`. +2. Global middleware `/custom/:id`. + +And the route middlewares are sorted into the following order before they're registered: + +1. Route middleware `/custom*`. +2. Route middleware `/custom/:id`. + +Then, the middlwares are registered in the order mentioned earlier, with global middlewares first, then the route middlewares. + +### Middlewares and Route Execution Order + +When a request is sent to an API route, the global middlewares are executed first, then the route middlewares, and finally the route handler. + +For example, consider you have the following middlewares: + +```ts title="src/api/middlewares.ts" +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom", + middlewares: [ + (req, res, next) => { + console.log("Global middleware") + next() + }, + ], + }, + { + matcher: "/custom", + method: ["GET"], + middlewares: [ + (req, res, next) => { + console.log("Route middleware") + next() + }, + ], + }, + ], +}) +``` + +When you send a request to `/custom` route, the following messages are logged in the terminal: + +```bash +Global middleware +Route middleware +Hello from custom! # message logged from API route handler +``` + +The global middleware runs first, then the route middleware, and finally the route handler, assuming that it logs the message `Hello from custom!`. + +*** + +## Overriding Middlewares + +A middleware can not override an existing middleware. Instead, middlewares are added to the end of the middleware stack. + +For example, if you define a custom validation middleware, such as `validateAndTransformBody`, on an existing route, then both the original and the custom validation middleware will run. + + +# HTTP Methods + +In this chapter, you'll learn about how to add new API routes for each HTTP method. + +## HTTP Method Handler + +An API route is created for every HTTP method you export a handler function for in a route file. + +Allowed HTTP methods are: `GET`, `POST`, `DELETE`, `PUT`, `PATCH`, `OPTIONS`, and `HEAD`. + +For example, create the file `src/api/hello-world/route.ts` with the following content: + +```ts title="src/api/hello-world/route.ts" +import type { MedusaRequest, MedusaResponse, } from "@medusajs/framework/http" @@ -6898,283 +7800,1083 @@ export const GET = async ( req: MedusaRequest, res: MedusaResponse ) => { - const query = req.scope.resolve("query") - - const { data: brands } = await query.graph({ - entity: "brand", - fields: ["*", "products.*"], + res.json({ + message: "[GET] Hello world!", }) +} - res.json({ brands }) +export const POST = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: "[POST] Hello world!", + }) } ``` -This adds a `GET` API route at `/admin/brands`. In the API route, you resolve Query from the Medusa container. Query has a `graph` method that runs a query to retrieve data. It accepts an object having the following properties: +This adds two API Routes: -- `entity`: The data model's name as specified in the first parameter of `model.define`. -- `fields`: An array of properties and relations to retrieve. You can pass: - - A property's name, such as `id`, or `*` for all properties. - - A relation or linked model's name, such as `products` (use the plural name since brands are linked to list of products). You suffix the name with `.*` to retrieve all its properties. +- A `GET` route at `http://localhost:9000/hello-world`. +- A `POST` route at `http://localhost:9000/hello-world`. -`graph` returns an object having a `data` property, which is the retrieved brands.

The first is the error's type. `MedusaError` has a static property `Types` that you can use. `Types` is an enum whose possible values are explained in the next section. +2. The second is the message to show in the error response. + +### Error Object in Response + +The error object returned in the response has two properties: + +- `type`: The error's type. +- `message`: The error message, if available. +- `code`: A common snake-case code. Its values can be: + - `invalid_request_error` for the `DUPLICATE_ERROR` type. + - `api_error`: for the `DB_ERROR` type. + - `invalid_state_error` for `CONFLICT` error type. + - `unknown_error` for any unidentified error type. + - For other error types, this property won't be available unless you provide a code as a third parameter to the `MedusaError` constructor. + +### MedusaError Types + +|Type|Description|Status Code| +|---|---|---|---|---| +|\`DB\_ERROR\`|Indicates a database error.|\`500\`| +|\`DUPLICATE\_ERROR\`|Indicates a duplicate of a record already exists.

A function of type MedusaNextFunction that executes the next middleware in the stack. + +This example overrides Medusa's default error handler with a handler that always returns a `400` status code with the same message. + + +# API Route Parameters + +In this chapter, you’ll learn about path, query, and request body parameters. + +## Path Parameters + +To create an API route that accepts a path parameter, create a directory within the route file's path whose name is of the format `[param]`. + +For example, to create an API Route at the path `/hello-world/:id`, where `:id` is a path parameter, create the file `src/api/hello-world/[id]/route.ts` with the following content: + +```ts title="src/api/hello-world/[id]/route.ts" highlights={singlePathHighlights} +import type { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: `[GET] Hello ${req.params.id}!`, + }) +} +``` + +The `MedusaRequest` object has a `params` property. `params` holds the path parameters in key-value pairs. + +### Multiple Path Parameters + +To create an API route that accepts multiple path parameters, create within the file's path multiple directories whose names are of the format `[param]`. + +For example, to create an API route at `/hello-world/:id/name/:name`, create the file `src/api/hello-world/[id]/name/[name]/route.ts` with the following content: + +```ts title="src/api/hello-world/[id]/name/[name]/route.ts" highlights={multiplePathHighlights} +import type { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: `[GET] Hello ${ + req.params.id + } - ${req.params.name}!`, + }) +} +``` + +You access the `id` and `name` path parameters using the `req.params` property. + +*** + +## Query Parameters + +You can access all query parameters in the `query` property of the `MedusaRequest` object. `query` is an object of key-value pairs, where the key is a query parameter's name, and the value is its value. + +For example: + +```ts title="src/api/hello-world/route.ts" highlights={queryHighlights} +import type { + MedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: `Hello ${req.query.name}`, + }) +} +``` + +The value of `req.query.name` is the value passed in `?name=John`, for example. + +### Validate Query Parameters + +You can apply validation rules on received query parameters to ensure they match specified rules and types. + +Learn more in [this documentation](https://docs.medusajs.com/learn/fundamentals/api-routes/validation#how-to-validate-request-query-paramters/index.html.md). + +*** + +## Request Body Parameters + +The Medusa application parses the body of any request having a JSON, URL-encoded, or text request content types.

This is useful for auto-completion and to avoid typing errors. + +To test it out, send the following request to your Medusa application: + +```bash +curl -X POST 'http://localhost:9000/hello-world' \ +-H 'Content-Type: application/json' \ +--data-raw '{ + "name": "John" +}' +``` + +This returns the following JSON object: + +```json +{ + "message": "[POST] Hello John!" +} +``` + +### Validate Body Parameters + +You can apply validation rules on received body parameters to ensure they match specified rules and types. + +Learn more in [this documentation](https://docs.medusajs.com/learn/fundamentals/api-routes/validation#how-to-validate-request-body/index.html.md). + + +# Configure Request Body Parser + +In this chapter, you'll learn how to configure the request body parser for your API routes. + +## Default Body Parser Configuration + +The Medusa application configures the body parser by default to parse JSON, URL-encoded, and text request content types. You can parse other data types by adding the relevant [Express middleware](https://expressjs.com/en/guide/using-middleware.html) or preserve the raw body data by configuring the body parser, which is useful for webhook requests. + +This chapter shares some examples of configuring the body parser for different data types or use cases. + +*** + +## Preserve Raw Body Data for Webhooks + +If your API route receives webhook requests, you might want to preserve the raw body data. To do this, you can configure the body parser to parse the raw body data and store it in the `req.rawBody` property. + +To do that, create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" highlights={preserveHighlights} +import { defineMiddlewares } from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + method: ["POST"], + bodyParser: { preserveRawBody: true }, + matcher: "/custom", + }, + ], +}) +``` + +The middleware route object passed to `routes` accepts a `bodyParser` property whose value is an object of configuration for the default body parser. By enabling the `preserveRawBody` property, the raw body data is preserved and stored in the `req.rawBody` property. + +Learn more about [middlewares](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md). + +You can then access the raw body data in your API route handler: + +```ts title="src/api/custom/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export async function POST( + req: MedusaRequest, + res: MedusaResponse +) { + console.log(req.rawBody) + + // TODO use raw body +} +``` + +*** + +## Configure Request Body Size Limit + +By default, the body parser limits the request body size to `100kb`. If a request body exceeds that size, the Medusa application throws an error. + +You can configure the body parser to accept larger request bodies by setting the `sizeLimit` property of the `bodyParser` object in a middleware route object. For example: + +```ts title="src/api/middlewares.ts" highlights={sizeLimitHighlights} +import { defineMiddlewares } from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + method: ["POST"], + bodyParser: { sizeLimit: "2mb" }, + matcher: "/custom", + }, + ], +}) +``` + +The `sizeLimit` property accepts one of the following types of values: + +- A string representing the size limit in bytes (For example, `100kb`, `2mb`, `5gb`). It is passed to the [bytes](https://www.npmjs.com/package/bytes) library to parse the size. +- A number representing the size limit in bytes. For example, `1024` for 1kb. + +*** + +## Configure File Uploads + +To accept file uploads in your API routes, you can configure the [Express Multer middleware](https://expressjs.com/en/resources/middleware/multer.html) on your route. + +The `multer` package is available through the `@medusajs/medusa` package, so you don't need to install it. However, for better typing support, install the `@types/multer` package as a development dependency: + +```bash npm2yarn +npm install --save-dev @types/multer +``` + +Then, to configure file upload for your route, create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" highlights={uploadHighlights} +import { defineMiddlewares } from "@medusajs/framework/http" +import multer from "multer" + +const upload = multer({ storage: multer.memoryStorage() }) + +export default defineMiddlewares({ + routes: [ + { + method: ["POST"], + matcher: "/custom", + middlewares: [ + // @ts-ignore + upload.array("files"), + ], + }, + ], +}) +``` + +In the example above, you configure the `multer` middleware to store the uploaded files in memory. Then, you apply the `upload.array("files")` middleware to the route to accept file uploads. By using the `array` method, you accept multiple file uploads with the same `files` field name. + +You can then access the uploaded files in your API route handler: + +```ts title="src/api/custom/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export async function POST( + req: MedusaRequest, + res: MedusaResponse +) { + const files = req.files as Express.Multer.File[] + + // TODO handle files +} +``` + +The uploaded files are stored in the `req.files` property as an array of Multer file objects that have properties like `filename` and `mimetype`. + +### Uploading Files using File Module Provider + +The recommended way to upload the files to storage using the configured [File Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/file/index.html.md) is to use the [uploadFilesWorkflow](https://docs.medusajs.com/resources/references/medusa-workflows/uploadFilesWorkflow/index.html.md): + +```ts title="src/api/custom/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" +import { MedusaError } from "@medusajs/framework/utils" +import { uploadFilesWorkflow } from "@medusajs/medusa/core-flows" + +export async function POST( + req: MedusaRequest, + res: MedusaResponse +) { + const files = req.files as Express.Multer.File[] + + if (!files?.length) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "No files were uploaded" + ) + } + + const { result } = await uploadFilesWorkflow(req.scope).run({ + input: { + files: files?.map((f) => ({ + filename: f.originalname, + mimeType: f.mimetype, + content: f.buffer.toString("binary"), + access: "public", + })), + }, + }) + + res.status(200).json({ files: result }) +} +``` + +Check out the [uploadFilesWorkflow reference](https://docs.medusajs.com/resources/references/medusa-workflows/uploadFilesWorkflow/index.html.md) for details on the expected input and output of the workflow. + + +# API Route Response + +In this chapter, you'll learn how to send a response in your API route. + +## Send a JSON Response + +To send a JSON response, use the `json` method of the `MedusaResponse` object passed as the second parameter of your API route handler. + +For example: + +```ts title="src/api/custom/route.ts" highlights={jsonHighlights} +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: "Hello, World!", + }) +} +``` + +This API route returns the following JSON object: + +```json +{ + "message": "Hello, World!" +} +``` + +*** + +## Set Response Status Code + +By default, setting the JSON data using the `json` method returns a response with a `200` status code. + +To change the status code, use the `status` method of the `MedusaResponse` object. + +For example: + +```ts title="src/api/custom/route.ts" highlights={statusHighlight} +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.status(201).json({ + message: "Hello, World!", + }) +} +``` + +The response of this API route has the status code `201`. + +*** + +## Change Response Content Type + +To return response data other than a JSON object, use the `writeHead` method of the `MedusaResponse` object. It allows you to set the response headers, including the content type. + +For example, to create an API route that returns an event stream: + +```ts highlights={streamHighlights} +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" + +export const GET = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.writeHead(200, { + "Content-Type": "text/event-stream", + "Cache-Control": "no-cache", + Connection: "keep-alive", + }) + + const interval = setInterval(() => { + res.write("Streaming data...\n") + }, 3000) + + req.on("end", () => { + clearInterval(interval) + res.end() + }) +} +``` + +The `writeHead` method accepts two parameters: + +1. The first one is the response's status code. +2. The second is an object of key-value pairs to set the headers of the response. + +This API route opens a stream by setting the `Content-Type` in the header to `text/event-stream`. It then simulates a stream by creating an interval that writes the stream data every three seconds. + +*** + +## Do More with Responses + +The `MedusaResponse` type is based on [Express's Response](https://expressjs.com/en/api.html#res). Refer to their API reference for other uses of responses. + + +# Protected Routes + +In this chapter, you’ll learn how to create protected routes. + +## What is a Protected Route? + +A protected route is a route that requires requests to be user-authenticated before performing the route's functionality. Otherwise, the request fails, and the user is prevented access. + +*** + +## Default Protected Routes + +Medusa applies an authentication guard on routes starting with `/admin`, including custom API routes. + +Requests to `/admin` must be user-authenticated to access the route. + +Refer to the API Reference for [Admin](https://docs.medusajs.com/api/admin#authentication) and [Store](https://docs.medusajs.com/api/store#authentication) authentication methods. + +*** + +## Protect Custom API Routes + +To protect custom API Routes to only allow authenticated customer or admin users, use the `authenticate` middleware from the Medusa Framework. + +For example: + +```ts title="src/api/middlewares.ts" highlights={highlights} +import { + defineMiddlewares, + authenticate, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom/admin*", + middlewares: [authenticate("user", ["session", "bearer", "api-key"])], + }, + { + matcher: "/custom/customer*", + middlewares: [authenticate("customer", ["session", "bearer"])], + }, + ], +}) +``` + +The `authenticate` middleware function accepts three parameters: + +1. The type of user authenticating. Use `user` for authenticating admin users, and `customer` for authenticating customers. You can also pass `*` to allow all types of users, or pass an array of actor types. +2. An array of types of authentication methods allowed. Both `user` and `customer` scopes support `session` and `bearer`. The `admin` scope also supports the `api-key` authentication method. +3. An optional object of configurations accepting the following properties: + - `allowUnauthenticated`: (default: `false`) A boolean indicating whether authentication is required. For example, you may have an API route where you want to access the logged-in customer if available, but guest customers can still access it too. + - `allowUnregistered` (default: `false`): A boolean indicating if unregistered users should be allowed access. This is useful when you want to allow users who aren’t registered to access certain routes. + +### Example: Custom Actor Type + +For example, to require authentication of a custom actor type `manager` to an API route: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + authenticate, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/manager*", + middlewares: [authenticate("manager", ["session", "bearer"])], + }, + ], +}) +``` + +Refer to the [Custom Actor-Type Guide](https://docs.medusajs.com/resources/commerce-modules/auth/create-actor-type/index.html.md) for detailed explanation on how to create a custom actor type and apply authentication middlewares. + +### Example: Allow Multiple Actor Types + +To allow multiple actor types to access an API route, pass an array of actor types to the `authenticate` middleware: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + authenticate, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom*", + middlewares: [authenticate(["user", "customer"], ["session", "bearer"])], + }, + ], +}) +``` + +*** + +## Authentication Opt-Out + +To disable the authentication guard on custom routes under the `/admin` path prefix, export an `AUTHENTICATE` variable in the route file with its value set to `false`. + +For example: + +```ts title="src/api/admin/custom/route.ts" highlights={[["15"]]} +import type { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" + +export const GET = async ( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) => { + res.json({ + message: "Hello", + }) +} + +export const AUTHENTICATE = false +``` + +Now, any request sent to the `/admin/custom` API route is allowed, regardless if the admin user is authenticated. + +*** + +## Authenticated Request Type + +To access the authentication details in an API route, such as the logged-in user's ID, set the type of the first request parameter to `AuthenticatedMedusaRequest`. It extends `MedusaRequest`. + +The `auth_context.actor_id` property of `AuthenticatedMedusaRequest` holds the ID of the authenticated user or customer. If there isn't any authenticated user or customer, `auth_context` is `undefined`. + +If you opt-out of authentication in a route as mentioned in the [previous section](#authentication-opt-out), you can't access the authenticated user or customer anymore. Use the [authenticate middleware](#protect-custom-api-routes) instead. + +### Retrieve Logged-In Customer's Details + +You can access the logged-in customer’s ID in all API routes starting with `/store` using the `auth_context.actor_id` property of the `AuthenticatedMedusaRequest` object. + +For example: + +```ts title="src/api/store/custom/route.ts" highlights={[["19", "req.auth_context.actor_id", "Access the logged-in customer's ID."]]} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import type { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { Modules } from "@medusajs/framework/utils" +import { ICustomerModuleService } from "@medusajs/framework/types" + +export const GET = async ( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) => { + if (req.auth_context?.actor_id) { + // retrieve customer + const customerModuleService: ICustomerModuleService = req.scope.resolve( + Modules.CUSTOMER + ) + + const customer = await customerModuleService.retrieveCustomer( + req.auth_context.actor_id + ) + } + + // ... +} +``` + +In this example, you resolve the Customer Module's main service, then use it to retrieve the logged-in customer, if available. + +### Retrieve Logged-In Admin User's Details + +You can access the logged-in admin user’s ID in all API Routes starting with `/admin` using the `auth_context.actor_id` property of the `AuthenticatedMedusaRequest` object. + +For example: + +```ts title="src/api/admin/custom/route.ts" highlights={[["17", "req.auth_context.actor_id", "Access the logged-in admin user's ID."]]} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import type { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { Modules } from "@medusajs/framework/utils" +import { IUserModuleService } from "@medusajs/framework/types" + +export const GET = async ( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) => { + const userModuleService: IUserModuleService = req.scope.resolve( + Modules.USER + ) + + const user = await userModuleService.retrieveUser( + req.auth_context.actor_id + ) + + // ... +} +``` + +In the route handler, you resolve the User Module's main service, then use it to retrieve the logged-in admin user. + + +# Retrieve Custom Links from Medusa's API Route + +In this chapter, you'll learn how to retrieve custom data models linked to existing Medusa data models from Medusa's API routes. + +## Why Retrieve Custom Linked Data Models? + +Often, you'll link custom data models to existing Medusa data models to implement custom features or expand on existing ones. + +For example, to add brands for products, you can create a `Brand` data model in a Brand Module, then [define a link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) to the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md)'s `Product` data model. + +When you implement this customization, you might need to retrieve the brand of a product using the existing [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid). You can do this by passing the linked data model's name in the `fields` query parameter of the API route. + +*** + +## How to Retrieve Custom Linked Data Models Using `fields`? + +Most of Medusa's API routes accept a `fields` query parameter that allows you to specify the fields and relations to retrieve in the resource, such as a product. + +For example, to retrieve the brand of a product, you can pass the `brand` field in the `fields` query parameter of the [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid): + +```bash +curl 'http://localhost:9000/admin/products/{id}?fields=*brand' \ +-H 'Authorization: Bearer {access_token}' +``` + +The `fields` query parameter accepts a comma-separated list of fields and relations to retrieve. To learn more about using the `fields` query parameter, refer to the [API Reference](https://docs.medusajs.com/api/store#select-fields-and-relations). + +By prefixing `brand` with an asterisk (`*`), you retrieve all the default fields of the product, including the `brand` field. If you don't include the `*` prefix, the response will only include the product's brand. + +*** + +## API Routes that Restrict Retrievable Fields + +Some of Medusa's API routes restrict the fields and relations you can retrieve, which means you can't pass your custom linked data models in the `fields` query parameter. Medusa makes this restriction to ensure the API routes are performant and secure. + +The API routes that restrict the fields and relations you can retrieve are: + +- [Customer Store API Routes](https://docs.medusajs.com/api/store#customers) +- [Customer Admin API Routes](https://docs.medusajs.com/api/admin#customers) +- [Product Category Admin API Routes](https://docs.medusajs.com/api/admin#product-categories) + +### How to Override Allowed Fields and Relations + +For these routes, you need to override the allowed fields and relations to be retrieved. You can do this by adding a [middleware](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md) to those routes. + +For example, to allow retrieving the `b2b_company` of a customer using the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid), create the file `src/api/middlewares.ts` with the following content: + +Learn how to create a middleware in the [Middlewares](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md) chapter. + +```ts title="src/api/middlewares.ts" highlights={highlights} +import { defineMiddlewares } from "@medusajs/medusa" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/customers/me", + method: "GET", + middlewares: [ + (req, res, next) => { + req.allowed?.push("b2b_company") + next() + }, + ], + }, + ], +}) +``` + +In this example, you apply a middleware to the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid). + +The request object passed to middlewares has an `allowed` property that contains the fields and relations that can be retrieved. So, you modify the `allowed` array to include the `b2b_company` field. + +You can now retrieve the `b2b_company` field using the `fields` query parameter of the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid): + +```bash +curl 'http://localhost:9000/admin/customers/{id}?fields=*b2b_company' \ +-H 'Authorization: Bearer {access_token}' +``` + +In this example, you retrieve the `b2b_company` relation of the customer using the `fields` query parameter. + + +# Request Body and Query Parameter Validation + +In this chapter, you'll learn how to validate request body and query parameters in your custom API route. + +## Request Validation + +Consider you're creating a `POST` API route at `/custom`. It accepts two parameters `a` and `b` that are required numbers, and returns their sum. + +Medusa provides two middlewares to validate the request body and query paramters of incoming requests to your custom API routes: + +- `validateAndTransformBody` to validate the request's body parameters against a schema. +- `validateAndTransformQuery` to validate the request's query parameters against a schema. + +Both middlewares accept a [Zod](https://zod.dev/) schema as a parameter, which gives you flexibility in how you define your validation schema with complex rules. + +The next steps explain how to add request body and query parameter validation to the API route mentioned earlier. + +*** + +## How to Validate Request Body + +### Step 1: Create Validation Schema + +Medusa uses [Zod](https://zod.dev/) to create validation schemas. These schemas are then used to validate incoming request bodies or query parameters. + +To create a validation schema with Zod, create a `validators.ts` file in any `src/api` subfolder. This file holds Zod schemas for each of your API routes. + +For example, create the file `src/api/custom/validators.ts` with the following content: + +```ts title="src/api/custom/validators.ts" +import { z } from "zod" + +export const PostStoreCustomSchema = z.object({ + a: z.number(), + b: z.number(), +}) +``` + +The `PostStoreCustomSchema` variable is a Zod schema that indicates the request body is valid if: + +1. It's an object. +2. It has a property `a` that is a required number. +3. It has a property `b` that is a required number. + +### Step 2: Add Request Body Validation Middleware + +To use this schema for validating the body parameters of requests to `/custom`, use the `validateAndTransformBody` middleware provided by `@medusajs/framework/http`. It accepts the Zod schema as a parameter. + +For example, create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformBody, +} from "@medusajs/framework/http" +import { PostStoreCustomSchema } from "./custom/validators" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom", + method: "POST", + middlewares: [ + validateAndTransformBody(PostStoreCustomSchema), + ], + }, + ], +}) +``` + +This applies the `validateAndTransformBody` middleware on `POST` requests to `/custom`. It uses the `PostStoreCustomSchema` as the validation schema. + +#### How the Validation Works + +If a request's body parameters don't pass the validation, the `validateAndTransformBody` middleware throws an error indicating the validation errors. + +If a request's body parameters are validated successfully, the middleware sets the validated body parameters in the `validatedBody` property of `MedusaRequest`. + +### Step 3: Use Validated Body in API Route + +In your API route, consume the validated body using the `validatedBody` property of `MedusaRequest`. + +For example, create the file `src/api/custom/route.ts` with the following content: + +```ts title="src/api/custom/route.ts" highlights={routeHighlights} +import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" +import { z } from "zod" +import { PostStoreCustomSchema } from "./validators" + +type PostStoreCustomSchemaType = z.infer< + typeof PostStoreCustomSchema +> + +export const POST = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + res.json({ + sum: req.validatedBody.a + req.validatedBody.b, + }) +} +``` + +In the API route, you use the `validatedBody` property of `MedusaRequest` to access the values of the `a` and `b` properties. + +To pass the request body's type as a type parameter to `MedusaRequest`, use Zod's `infer` type that accepts the type of a schema as a parameter. ### Test it Out -To test the API route out, send a `GET` request to `/admin/brands`: +To test out the validation, send a `POST` request to `/custom` passing `a` and `b` body parameters. You can try sending incorrect request body parameters to test out the validation. -```bash -curl 'http://localhost:9000/admin/brands' \ --H 'Authorization: Bearer {token}' -``` +For example, if you omit the `a` parameter, you'll receive a `400` response code with the following response data: -Make sure to replace `{token}` with your admin user's authentication token.

A service's constructor accepts two parameters: - -1. The module's container. Since a module is [isolated](https://docs.medusajs.com/learn/fundamentals/modules/isolation/index.html.md), it has a [local container](https://docs.medusajs.com/learn/fundamentals/modules/container/index.html.md) different than the Medusa container you use in other customizations. This container holds Framework tools like the [Logger utility](https://docs.medusajs.com/learn/debugging-and-testing/logging/index.html.md) and resources within the module. -2. Options passed to the module when it's later added in Medusa's configurations. These options are useful to pass secret keys or configurations that ensure your module is re-usable across applications. For the CMS Module, you accept the API key to connect to the dummy CMS as an option. - -When integrating a third-party system that has a Node.js SDK or client, you can initialize that client in the constructor to be used in the service's methods. - -### Integration Methods - -Next, you'll add methods that simulate sending requests to a third-party CMS.

-### Compensation Function - -Hooks also accept a compensation function as a second parameter to undo the actions made by the step function. - -For example, pass the following second parameter to the `productsCreated` hook: - -```ts title="src/workflows/hooks/product-created.ts" -createProductsWorkflow.hooks.productsCreated( - async ({ products, additional_data }, { container }) => { - // ... - }, - async ({ products, additional_data }, { container }) => { -

-For example, if you allow only origins starting with `http://localhost:7001` to access your Admin API Routes, other origins accessing those routes get a CORS error. - -### CORS Configurations - -The `storeCors` and `adminCors` properties of Medusa's `http` configuration set the allowed origins for routes starting with `/store` and `/admin` respectively. - -These configurations accept a URL pattern to identify allowed origins. - -For example: - -```js title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - storeCors: "http://localhost:8000", - adminCors: "http://localhost:7001", - // ... - }, - }, -}) -``` - -This allows the `http://localhost:7001` origin to access the Admin API Routes, and the `http://localhost:8000` origin to access Store API Routes. - -Learn more about the CORS configurations in [this resource guide](https://docs.medusajs.com/learn/configurations/medusa-config#http/index.html.md). - -*** - -## CORS in Store and Admin Routes - -To disable the CORS middleware for a route, export a `CORS` variable in the route file with its value set to `false`. - -For example: - -```ts title="src/api/store/custom/route.ts" highlights={[["15"]]} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: "[GET] Hello world!", - }) -} - -export const CORS = false -``` - -This disables the CORS middleware on API Routes at the path `/store/custom`. - -*** - -## CORS in Custom Routes - -If you create a route that doesn’t start with `/store` or `/admin`, you must apply the CORS middleware manually. Otherwise, all requests to your API route lead to a CORS error. - -You can do that in the exported middlewares configurations in `src/api/middlewares.ts`. - -For example: - -```ts title="src/api/middlewares.ts" highlights={highlights} collapsibleLines="1-10" expandButtonLabel="Show Imports" -import { defineMiddlewares } from "@medusajs/framework/http" -import type { - MedusaNextFunction, - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { ConfigModule } from "@medusajs/framework/types" -import { parseCorsOrigins } from "@medusajs/framework/utils" -import cors from "cors" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom*", - middlewares: [ - ( - req: MedusaRequest, - res: MedusaResponse, - next: MedusaNextFunction - ) => { - const configModule: ConfigModule = - req.scope.resolve("configModule") - - return cors({ - origin: parseCorsOrigins( - configModule.projectConfig.http.storeCors - ), - credentials: true, - })(req, res, next) - }, - ], - }, - ], -}) -``` - -This retrieves the configurations exported from `medusa-config.ts` and applies the `storeCors` to routes starting with `/custom`. - - -# 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. The first is the error's type. `MedusaError` has a static property `Types` that you can use. `Types` is an enum whose possible values are explained in the next section. -2. The second is the message to show in the error response. - -### Error Object in Response - -The error object returned in the response has two properties: - -- `type`: The error's type. -- `message`: The error message, if available. -- `code`: A common snake-case code. Its values can be: - - `invalid_request_error` for the `DUPLICATE_ERROR` type. - - `api_error`: for the `DB_ERROR` type. - - `invalid_state_error` for `CONFLICT` error type. - - `unknown_error` for any unidentified error type. - - For other error types, this property won't be available unless you provide a code as a third parameter to the `MedusaError` constructor. - -### MedusaError Types - -|Type|Description|Status Code| -|---|---|---|---|---| -|\`DB\_ERROR\`|Indicates a database error.|\`500\`| -|\`DUPLICATE\_ERROR\`|Indicates a duplicate of a record already exists. For example, when trying to create a customer whose email is registered by another customer.|\`422\`| -|\`INVALID\_ARGUMENT\`|Indicates an error that occurred due to incorrect arguments or other unexpected state.|\`500\`| -|\`INVALID\_DATA\`|Indicates a validation error.|\`400\`| -|\`UNAUTHORIZED\`|Indicates that a user is not authorized to perform an action or access a route.|\`401\`| -|\`NOT\_FOUND\`|Indicates that the requested resource, such as a route or a record, isn't found.|\`404\`| -|\`NOT\_ALLOWED\`|Indicates that an operation isn't allowed.|\`400\`| -|\`CONFLICT\`|Indicates that a request conflicts with another previous or ongoing request.

Use it to override the default error handler for API routes. - -This error handler will also be used for errors thrown in Medusa's API routes and resources. - -For example, create `src/api/middlewares.ts` with the following: - -```ts title="src/api/middlewares.ts" collapsibleLines="1-8" expandMoreLabel="Show Imports" -import { - defineMiddlewares, - MedusaNextFunction, - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { MedusaError } from "@medusajs/framework/utils" - -export default defineMiddlewares({ - errorHandler: ( - error: MedusaError | any, - req: MedusaRequest, - res: MedusaResponse, - next: MedusaNextFunction - ) => { - res.status(400).json({ - error: "Something happened.", - }) - }, -}) -``` - -The `errorHandler` property's value is a function that accepts four parameters: - -1. The error thrown. Its type can be `MedusaError` or any other thrown error type. -2. A request object of type `MedusaRequest`. -3. A response object of type `MedusaResponse`. -4. A function of type MedusaNextFunction that executes the next middleware in the stack. - -This example overrides Medusa's default error handler with a handler that always returns a `400` status code with the same message. - - -# HTTP Methods - -In this chapter, you'll learn about how to add new API routes for each HTTP method. - -## HTTP Method Handler - -An API route is created for every HTTP method you export a handler function for in a route file. - -Allowed HTTP methods are: `GET`, `POST`, `DELETE`, `PUT`, `PATCH`, `OPTIONS`, and `HEAD`. - -For example, create the file `src/api/hello-world/route.ts` with the following content: - -```ts title="src/api/hello-world/route.ts" -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: "[GET] Hello world!", - }) -} - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: "[POST] Hello world!", - }) -} -``` - -This adds two API Routes: - -- A `GET` route at `http://localhost:9000/hello-world`. -- A `POST` route at `http://localhost:9000/hello-world`. - - -# API Route Parameters - -In this chapter, you’ll learn about path, query, and request body parameters. - -## Path Parameters - -To create an API route that accepts a path parameter, create a directory within the route file's path whose name is of the format `[param]`. - -For example, to create an API Route at the path `/hello-world/:id`, where `:id` is a path parameter, create the file `src/api/hello-world/[id]/route.ts` with the following content: - -```ts title="src/api/hello-world/[id]/route.ts" highlights={singlePathHighlights} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: `[GET] Hello ${req.params.id}!`, - }) -} -``` - -The `MedusaRequest` object has a `params` property. `params` holds the path parameters in key-value pairs. - -### Multiple Path Parameters - -To create an API route that accepts multiple path parameters, create within the file's path multiple directories whose names are of the format `[param]`. - -For example, to create an API route at `/hello-world/:id/name/:name`, create the file `src/api/hello-world/[id]/name/[name]/route.ts` with the following content: - -```ts title="src/api/hello-world/[id]/name/[name]/route.ts" highlights={multiplePathHighlights} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: `[GET] Hello ${ - req.params.id - } - ${req.params.name}!`, - }) -} -``` - -You access the `id` and `name` path parameters using the `req.params` property. - -*** - -## Query Parameters - -You can access all query parameters in the `query` property of the `MedusaRequest` object. `query` is an object of key-value pairs, where the key is a query parameter's name, and the value is its value. - -For example: - -```ts title="src/api/hello-world/route.ts" highlights={queryHighlights} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: `Hello ${req.query.name}`, - }) -} -``` - -The value of `req.query.name` is the value passed in `?name=John`, for example. - -### Validate Query Parameters - -You can apply validation rules on received query parameters to ensure they match specified rules and types. - -Learn more in [this documentation](https://docs.medusajs.com/learn/fundamentals/api-routes/validation#how-to-validate-request-query-paramters/index.html.md). - -*** - -## Request Body Parameters - -The Medusa application parses the body of any request having a JSON, URL-encoded, or text request content types. The request body parameters are set in the `MedusaRequest`'s `body` property. - -Learn more about configuring body parsing in [this guide](https://docs.medusajs.com/learn/fundamentals/api-routes/parse-body/index.html.md). - -For example: - -```ts title="src/api/hello-world/route.ts" highlights={bodyHighlights} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -type HelloWorldReq = { - name: string -} - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: `[POST] Hello ${req.body.name}!`, - }) -} -``` - -In this example, you use the `name` request body parameter to create the message in the returned response. - -The `MedusaRequest` type accepts a type argument that indicates the type of the request body. This is useful for auto-completion and to avoid typing errors. - -To test it out, send the following request to your Medusa application: - -```bash -curl -X POST 'http://localhost:9000/hello-world' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "name": "John" -}' -``` - -This returns the following JSON object: - -```json -{ - "message": "[POST] Hello John!" -} -``` - -### Validate Body Parameters - -You can apply validation rules on received body parameters to ensure they match specified rules and types. - -Learn more in [this documentation](https://docs.medusajs.com/learn/fundamentals/api-routes/validation#how-to-validate-request-body/index.html.md). - - -# Middlewares - -In this chapter, you’ll learn about middlewares and how to create them. - -## What is a Middleware? - -A middleware is a function executed when a request is sent to an API Route. It's executed before the route handler function. - -Middlewares are used to guard API routes, parse request content types other than `application/json`, manipulate request data, and more. - -As Medusa's server is based on Express, you can use any [Express middleware](https://expressjs.com/en/resources/middleware.html). - -### Middleware Types - -There are two types of middlewares: - -1. Global Middleware: A middleware that applies to all routes matching a specified pattern. -2. Route Middleware: A middleware that applies to routes matching a specified pattern and HTTP method(s). - -These middlewares generally have the same definition and usage, but they differ in the routes they apply to. You'll learn how to create both types in the following sections. - -*** - -## How to Create a Global Middleware? - -Middlewares of all types are defined in the special file `src/api/middlewares.ts`. Use the `defineMiddlewares` function from the Medusa Framework to define the middlewares, and export its value. - -For example: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - MedusaNextFunction, - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom*", - middlewares: [ - ( - req: MedusaRequest, - res: MedusaResponse, - next: MedusaNextFunction - ) => { - console.log("Received a request!") - - next() - }, - ], - }, - ], -}) -``` - -The `defineMiddlewares` function accepts a middleware configurations object that has the property `routes`. `routes`'s value is an array of middleware route objects, each having the following properties: - -- `matcher`: a string or regular expression indicating the API route path to apply the middleware on. The regular expression must be compatible with [path-to-regexp](https://github.com/pillarjs/path-to-regexp). -- `middlewares`: An array of global and route middleware functions. - -In the example above, you define a global middleware that logs the message `Received a request!` whenever a request is sent to an API route path starting with `/custom`. - -### Test the Global Middleware - -To test the middleware: - -1. Start the application: - -```bash npm2yarn -npm run dev -``` - -2. Send a request to any API route starting with `/custom`. -3. See the following message in the terminal: - -```bash -Received a request! -``` - -*** - -## How to Create a Route Middleware? - -In the previous section, you learned how to create a global middleware. You define the route middleware in the same way in `src/api/middlewares.ts`, but you specify an additional property `method` in the middleware route object. Its value is one or more HTTP methods to apply the middleware to. - -For example: - -```ts title="src/api/middlewares.ts" highlights={highlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - MedusaNextFunction, - MedusaRequest, - MedusaResponse, - defineMiddlewares, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom*", - method: ["POST", "PUT"], - middlewares: [ - ( - req: MedusaRequest, - res: MedusaResponse, - next: MedusaNextFunction - ) => { - console.log("Received a request!") - - next() - }, - ], - }, - ], -}) -``` - -This example applies the middleware only when a `POST` or `PUT` request is sent to an API route path starting with `/custom`, changing the middleware from a global middleware to a route middleware. - -### Test the Route Middleware - -To test the middleware: - -1. Start the application: - -```bash npm2yarn -npm run dev -``` - -2. Send a `POST` request to any API route starting with `/custom`. -3. See the following message in the terminal: - -```bash -Received a request! -``` - -*** - -## When to Use Middlewares - -- You want to protect API routes by a custom condition. -- You're modifying the request body. - -*** - -## Middleware Function Parameters - -The middleware function accepts three parameters: - -1. A request object of type `MedusaRequest`. -2. A response object of type `MedusaResponse`. -3. A function of type `MedusaNextFunction` that executes the next middleware in the stack. - -You must call the `next` function in the middleware. Otherwise, other middlewares and the API route handler won’t execute. - -*** - -## Middleware for Routes with Path Parameters - -To indicate a path parameter in a middleware's `matcher` pattern, use the format `:{param-name}`. - -For example: - -```ts title="src/api/middlewares.ts" collapsibleLines="1-7" expandMoreLabel="Show Imports" highlights={pathParamHighlights} -import { - MedusaNextFunction, - MedusaRequest, - MedusaResponse, - defineMiddlewares, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom/:id", - middlewares: [ - // ... - ], - }, - ], -}) -``` - -This applies a middleware to the routes defined in the file `src/api/custom/[id]/route.ts`. - -*** - -## Request URLs with Trailing Backslashes - -A middleware whose `matcher` pattern doesn't end with a backslash won't be applied for requests to URLs with a trailing backslash. - -For example, consider you have the following middleware: - -```ts title="src/api/middlewares.ts" collapsibleLines="1-7" expandMoreLabel="Show Imports" -import { - MedusaNextFunction, - MedusaRequest, - MedusaResponse, - defineMiddlewares, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom", - middlewares: [ - ( - req: MedusaRequest, - res: MedusaResponse, - next: MedusaNextFunction - ) => { - console.log("Received a request!") - - next() - }, - ], - }, - ], -}) -``` - -If you send a request to `http://localhost:9000/custom`, the middleware will run. - -However, if you send a request to `http://localhost:9000/custom/`, the middleware won't run. - -In general, avoid adding trailing backslashes when sending requests to API routes. - -*** - -## Middlewares and Route Ordering - -The ordering explained in this section was added in [Medusa v2.6](https://github.com/medusajs/medusa/releases/tag/v2.6) - -The Medusa application registers middlewares and API route handlers in the following order: - -1. Global middlewares in the following order: - 1. Global middleware defined in the Medusa's core. - 2. Global middleware defined in the plugins (in the order the plugins are registered in). - 3. Global middleware you define in the application. -2. Route middlewares in the following order: - 1. Route middleware defined in the Medusa's core. - 2. Route middleware defined in the plugins (in the order the plugins are registered in). - 3. Route middleware you define in the application. -3. API routes in the following order: - 1. API routes defined in the Medusa's core. - 2. API routes defined in the plugins (in the order the plugins are registered in). - 3. API routes you define in the application. - -### Middlewares Sorting - -On top of the previous ordering, Medusa sorts global and route middlewares based on their matcher pattern in the following order: - -1. Wildcard matchers. For example, `/custom*`. -2. Regex matchers. For example, `/custom/(products|collections)`. -3. Static matchers without parameters. For example, `/custom`. -4. Static matchers with parameters. For example, `/custom/:id`. - -For example, if you have the following middlewares: - -```ts title="src/api/middlewares.ts" -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom/:id", - middlewares: [/* ... */], - }, - { - matcher: "/custom", - middlewares: [/* ... */], - }, - { - matcher: "/custom*", - method: ["GET"], - middlewares: [/* ... */], - }, - { - matcher: "/custom/:id", - method: ["GET"], - middlewares: [/* ... */], - }, - ], -}) -``` - -The global middlewares are sorted into the following order before they're registered: - -1. Global middleware `/custom`. -2. Global middleware `/custom/:id`. - -And the route middlewares are sorted into the following order before they're registered: - -1. Route middleware `/custom*`. -2. Route middleware `/custom/:id`. - -Then, the middlwares are registered in the order mentioned earlier, with global middlewares first, then the route middlewares. - -### Middlewares and Route Execution Order - -When a request is sent to an API route, the global middlewares are executed first, then the route middlewares, and finally the route handler. - -For example, consider you have the following middlewares: - -```ts title="src/api/middlewares.ts" -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom", - middlewares: [ - (req, res, next) => { - console.log("Global middleware") - next() - }, - ], - }, - { - matcher: "/custom", - method: ["GET"], - middlewares: [ - (req, res, next) => { - console.log("Route middleware") - next() - }, - ], - }, - ], -}) -``` - -When you send a request to `/custom` route, the following messages are logged in the terminal: - -```bash -Global middleware -Route middleware -Hello from custom! # message logged from API route handler -``` - -The global middleware runs first, then the route middleware, and finally the route handler, assuming that it logs the message `Hello from custom!`. - -*** - -## Overriding Middlewares - -A middleware can not override an existing middleware. Instead, middlewares are added to the end of the middleware stack. - -For example, if you define a custom validation middleware, such as `validateAndTransformBody`, on an existing route, then both the original and the custom validation middleware will run. - - -# Configure Request Body Parser - -In this chapter, you'll learn how to configure the request body parser for your API routes. - -## Default Body Parser Configuration - -The Medusa application configures the body parser by default to parse JSON, URL-encoded, and text request content types. You can parse other data types by adding the relevant [Express middleware](https://expressjs.com/en/guide/using-middleware.html) or preserve the raw body data by configuring the body parser, which is useful for webhook requests. - -This chapter shares some examples of configuring the body parser for different data types or use cases. - -*** - -## Preserve Raw Body Data for Webhooks - -If your API route receives webhook requests, you might want to preserve the raw body data. To do this, you can configure the body parser to parse the raw body data and store it in the `req.rawBody` property. - -To do that, create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" highlights={preserveHighlights} -import { defineMiddlewares } from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - method: ["POST"], - bodyParser: { preserveRawBody: true }, - matcher: "/custom", - }, - ], -}) -``` - -The middleware route object passed to `routes` accepts a `bodyParser` property whose value is an object of configuration for the default body parser. By enabling the `preserveRawBody` property, the raw body data is preserved and stored in the `req.rawBody` property. - -Learn more about [middlewares](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md). - -You can then access the raw body data in your API route handler: - -```ts title="src/api/custom/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export async function POST( - req: MedusaRequest, - res: MedusaResponse -) { - console.log(req.rawBody) - - // TODO use raw body -} -``` - -*** - -## Configure Request Body Size Limit - -By default, the body parser limits the request body size to `100kb`. If a request body exceeds that size, the Medusa application throws an error. - -You can configure the body parser to accept larger request bodies by setting the `sizeLimit` property of the `bodyParser` object in a middleware route object. For example: - -```ts title="src/api/middlewares.ts" highlights={sizeLimitHighlights} -import { defineMiddlewares } from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - method: ["POST"], - bodyParser: { sizeLimit: "2mb" }, - matcher: "/custom", - }, - ], -}) -``` - -The `sizeLimit` property accepts one of the following types of values: - -- A string representing the size limit in bytes (For example, `100kb`, `2mb`, `5gb`). It is passed to the [bytes](https://www.npmjs.com/package/bytes) library to parse the size. -- A number representing the size limit in bytes. For example, `1024` for 1kb. - -*** - -## Configure File Uploads - -To accept file uploads in your API routes, you can configure the [Express Multer middleware](https://expressjs.com/en/resources/middleware/multer.html) on your route. - -The `multer` package is available through the `@medusajs/medusa` package, so you don't need to install it. However, for better typing support, install the `@types/multer` package as a development dependency: - -```bash npm2yarn -npm install --save-dev @types/multer -``` - -Then, to configure file upload for your route, create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" highlights={uploadHighlights} -import { defineMiddlewares } from "@medusajs/framework/http" -import multer from "multer" - -const upload = multer({ storage: multer.memoryStorage() }) - -export default defineMiddlewares({ - routes: [ - { - method: ["POST"], - matcher: "/custom", - middlewares: [ - // @ts-ignore - upload.array("files"), - ], - }, - ], -}) -``` - -In the example above, you configure the `multer` middleware to store the uploaded files in memory. Then, you apply the `upload.array("files")` middleware to the route to accept file uploads. By using the `array` method, you accept multiple file uploads with the same `files` field name. - -You can then access the uploaded files in your API route handler: - -```ts title="src/api/custom/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export async function POST( - req: MedusaRequest, - res: MedusaResponse -) { - const files = req.files as Express.Multer.File[] - - // TODO handle files -} -``` - -The uploaded files are stored in the `req.files` property as an array of Multer file objects that have properties like `filename` and `mimetype`. - -### Uploading Files using File Module Provider - -The recommended way to upload the files to storage using the configured [File Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/file/index.html.md) is to use the [uploadFilesWorkflow](https://docs.medusajs.com/resources/references/medusa-workflows/uploadFilesWorkflow/index.html.md): - -```ts title="src/api/custom/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" -import { MedusaError } from "@medusajs/framework/utils" -import { uploadFilesWorkflow } from "@medusajs/medusa/core-flows" - -export async function POST( - req: MedusaRequest, - res: MedusaResponse -) { - const files = req.files as Express.Multer.File[] - - if (!files?.length) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "No files were uploaded" - ) - } - - const { result } = await uploadFilesWorkflow(req.scope).run({ - input: { - files: files?.map((f) => ({ - filename: f.originalname, - mimeType: f.mimetype, - content: f.buffer.toString("binary"), - access: "public", - })), - }, - }) - - res.status(200).json({ files: result }) -} -``` - -Check out the [uploadFilesWorkflow reference](https://docs.medusajs.com/resources/references/medusa-workflows/uploadFilesWorkflow/index.html.md) for details on the expected input and output of the workflow. - - -# Protected Routes - -In this chapter, you’ll learn how to create protected routes. - -## What is a Protected Route? - -A protected route is a route that requires requests to be user-authenticated before performing the route's functionality. Otherwise, the request fails, and the user is prevented access. - -*** - -## Default Protected Routes - -Medusa applies an authentication guard on routes starting with `/admin`, including custom API routes. - -Requests to `/admin` must be user-authenticated to access the route. - -Refer to the API Reference for [Admin](https://docs.medusajs.com/api/admin#authentication) and [Store](https://docs.medusajs.com/api/store#authentication) authentication methods. - -*** - -## Protect Custom API Routes - -To protect custom API Routes to only allow authenticated customer or admin users, use the `authenticate` middleware from the Medusa Framework. - -For example: - -```ts title="src/api/middlewares.ts" highlights={highlights} -import { - defineMiddlewares, - authenticate, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom/admin*", - middlewares: [authenticate("user", ["session", "bearer", "api-key"])], - }, - { - matcher: "/custom/customer*", - middlewares: [authenticate("customer", ["session", "bearer"])], - }, - ], -}) -``` - -The `authenticate` middleware function accepts three parameters: - -1. The type of user authenticating. Use `user` for authenticating admin users, and `customer` for authenticating customers. You can also pass `*` to allow all types of users, or pass an array of actor types. -2. An array of types of authentication methods allowed. Both `user` and `customer` scopes support `session` and `bearer`. The `admin` scope also supports the `api-key` authentication method. -3. An optional object of configurations accepting the following properties: - - `allowUnauthenticated`: (default: `false`) A boolean indicating whether authentication is required. For example, you may have an API route where you want to access the logged-in customer if available, but guest customers can still access it too. - - `allowUnregistered` (default: `false`): A boolean indicating if unregistered users should be allowed access. This is useful when you want to allow users who aren’t registered to access certain routes. - -### Example: Custom Actor Type - -For example, to require authentication of a custom actor type `manager` to an API route: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - authenticate, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/manager*", - middlewares: [authenticate("manager", ["session", "bearer"])], - }, - ], -}) -``` - -Refer to the [Custom Actor-Type Guide](https://docs.medusajs.com/resources/commerce-modules/auth/create-actor-type/index.html.md) for detailed explanation on how to create a custom actor type and apply authentication middlewares. - -### Example: Allow Multiple Actor Types - -To allow multiple actor types to access an API route, pass an array of actor types to the `authenticate` middleware: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - authenticate, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom*", - middlewares: [authenticate(["user", "customer"], ["session", "bearer"])], - }, - ], -}) -``` - -*** - -## Authentication Opt-Out - -To disable the authentication guard on custom routes under the `/admin` path prefix, export an `AUTHENTICATE` variable in the route file with its value set to `false`. - -For example: - -```ts title="src/api/admin/custom/route.ts" highlights={[["15"]]} -import type { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" - -export const GET = async ( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: "Hello", - }) -} - -export const AUTHENTICATE = false -``` - -Now, any request sent to the `/admin/custom` API route is allowed, regardless if the admin user is authenticated. - -*** - -## Authenticated Request Type - -To access the authentication details in an API route, such as the logged-in user's ID, set the type of the first request parameter to `AuthenticatedMedusaRequest`. It extends `MedusaRequest`. - -The `auth_context.actor_id` property of `AuthenticatedMedusaRequest` holds the ID of the authenticated user or customer. If there isn't any authenticated user or customer, `auth_context` is `undefined`. - -If you opt-out of authentication in a route as mentioned in the [previous section](#authentication-opt-out), you can't access the authenticated user or customer anymore. Use the [authenticate middleware](#protect-custom-api-routes) instead. - -### Retrieve Logged-In Customer's Details - -You can access the logged-in customer’s ID in all API routes starting with `/store` using the `auth_context.actor_id` property of the `AuthenticatedMedusaRequest` object. - -For example: - -```ts title="src/api/store/custom/route.ts" highlights={[["19", "req.auth_context.actor_id", "Access the logged-in customer's ID."]]} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import type { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { Modules } from "@medusajs/framework/utils" -import { ICustomerModuleService } from "@medusajs/framework/types" - -export const GET = async ( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) => { - if (req.auth_context?.actor_id) { - // retrieve customer - const customerModuleService: ICustomerModuleService = req.scope.resolve( - Modules.CUSTOMER - ) - - const customer = await customerModuleService.retrieveCustomer( - req.auth_context.actor_id - ) - } - - // ... -} -``` - -In this example, you resolve the Customer Module's main service, then use it to retrieve the logged-in customer, if available. - -### Retrieve Logged-In Admin User's Details - -You can access the logged-in admin user’s ID in all API Routes starting with `/admin` using the `auth_context.actor_id` property of the `AuthenticatedMedusaRequest` object. - -For example: - -```ts title="src/api/admin/custom/route.ts" highlights={[["17", "req.auth_context.actor_id", "Access the logged-in admin user's ID."]]} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import type { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { Modules } from "@medusajs/framework/utils" -import { IUserModuleService } from "@medusajs/framework/types" - -export const GET = async ( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) => { - const userModuleService: IUserModuleService = req.scope.resolve( - Modules.USER - ) - - const user = await userModuleService.retrieveUser( - req.auth_context.actor_id - ) - - // ... -} -``` - -In the route handler, you resolve the User Module's main service, then use it to retrieve the logged-in admin user. - - -# API Route Response - -In this chapter, you'll learn how to send a response in your API route. - -## Send a JSON Response - -To send a JSON response, use the `json` method of the `MedusaResponse` object passed as the second parameter of your API route handler. - -For example: - -```ts title="src/api/custom/route.ts" highlights={jsonHighlights} -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - message: "Hello, World!", - }) -} -``` - -This API route returns the following JSON object: - -```json -{ - "message": "Hello, World!" -} -``` - -*** - -## Set Response Status Code - -By default, setting the JSON data using the `json` method returns a response with a `200` status code. - -To change the status code, use the `status` method of the `MedusaResponse` object. - -For example: - -```ts title="src/api/custom/route.ts" highlights={statusHighlight} -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.status(201).json({ - message: "Hello, World!", - }) -} -``` - -The response of this API route has the status code `201`. - -*** - -## Change Response Content Type - -To return response data other than a JSON object, use the `writeHead` method of the `MedusaResponse` object. It allows you to set the response headers, including the content type. - -For example, to create an API route that returns an event stream: - -```ts highlights={streamHighlights} -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.writeHead(200, { - "Content-Type": "text/event-stream", - "Cache-Control": "no-cache", - Connection: "keep-alive", - }) - - const interval = setInterval(() => { - res.write("Streaming data...\n") - }, 3000) - - req.on("end", () => { - clearInterval(interval) - res.end() - }) -} -``` - -The `writeHead` method accepts two parameters: - -1. The first one is the response's status code. -2. The second is an object of key-value pairs to set the headers of the response. - -This API route opens a stream by setting the `Content-Type` in the header to `text/event-stream`. It then simulates a stream by creating an interval that writes the stream data every three seconds. - -*** - -## Do More with Responses - -The `MedusaResponse` type is based on [Express's Response](https://expressjs.com/en/api.html#res). Refer to their API reference for other uses of responses. - - -# 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. - - -# Request Body and Query Parameter Validation - -In this chapter, you'll learn how to validate request body and query parameters in your custom API route. - -## Request Validation - -Consider you're creating a `POST` API route at `/custom`. It accepts two parameters `a` and `b` that are required numbers, and returns their sum. - -Medusa provides two middlewares to validate the request body and query paramters of incoming requests to your custom API routes: - -- `validateAndTransformBody` to validate the request's body parameters against a schema. -- `validateAndTransformQuery` to validate the request's query parameters against a schema. - -Both middlewares accept a [Zod](https://zod.dev/) schema as a parameter, which gives you flexibility in how you define your validation schema with complex rules. - -The next steps explain how to add request body and query parameter validation to the API route mentioned earlier. - -*** - -## How to Validate Request Body - -### Step 1: Create Validation Schema - -Medusa uses [Zod](https://zod.dev/) to create validation schemas. These schemas are then used to validate incoming request bodies or query parameters. - -To create a validation schema with Zod, create a `validators.ts` file in any `src/api` subfolder. This file holds Zod schemas for each of your API routes. - -For example, create the file `src/api/custom/validators.ts` with the following content: - -```ts title="src/api/custom/validators.ts" -import { z } from "zod" - -export const PostStoreCustomSchema = z.object({ - a: z.number(), - b: z.number(), -}) -``` - -The `PostStoreCustomSchema` variable is a Zod schema that indicates the request body is valid if: - -1. It's an object. -2. It has a property `a` that is a required number. -3. It has a property `b` that is a required number. - -### Step 2: Add Request Body Validation Middleware - -To use this schema for validating the body parameters of requests to `/custom`, use the `validateAndTransformBody` middleware provided by `@medusajs/framework/http`. It accepts the Zod schema as a parameter. - -For example, create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { PostStoreCustomSchema } from "./custom/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom", - method: "POST", - middlewares: [ - validateAndTransformBody(PostStoreCustomSchema), - ], - }, - ], -}) -``` - -This applies the `validateAndTransformBody` middleware on `POST` requests to `/custom`. It uses the `PostStoreCustomSchema` as the validation schema. - -#### How the Validation Works - -If a request's body parameters don't pass the validation, the `validateAndTransformBody` middleware throws an error indicating the validation errors. - -If a request's body parameters are validated successfully, the middleware sets the validated body parameters in the `validatedBody` property of `MedusaRequest`. - -### Step 3: Use Validated Body in API Route - -In your API route, consume the validated body using the `validatedBody` property of `MedusaRequest`. - -For example, create the file `src/api/custom/route.ts` with the following content: - -```ts title="src/api/custom/route.ts" highlights={routeHighlights} -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" -import { z } from "zod" -import { PostStoreCustomSchema } from "./validators" - -type PostStoreCustomSchemaType = z.infer< - typeof PostStoreCustomSchema -> - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - res.json({ - sum: req.validatedBody.a + req.validatedBody.b, - }) -} -``` - -In the API route, you use the `validatedBody` property of `MedusaRequest` to access the values of the `a` and `b` properties. - -To pass the request body's type as a type parameter to `MedusaRequest`, use Zod's `infer` type that accepts the type of a schema as a parameter. - -### Test it Out - -To test out the validation, send a `POST` request to `/custom` passing `a` and `b` body parameters. You can try sending incorrect request body parameters to test out the validation. - -For example, if you omit the `a` parameter, you'll receive a `400` response code with the following response data: - -```json -{ - "type": "invalid_data", - "message": "Invalid request: Field 'a' is required" -} -``` - -*** - -## How to Validate Request Query Parameters - -The steps to validate the request query parameters are the similar to that of [validating the body](#how-to-validate-request-body). - -### Step 1: Create Validation Schema - -The first step is to create a schema with Zod with the rules of the accepted query parameters. - -Consider that the API route accepts two query parameters `a` and `b` that are numbers, similar to the previous section. - -Create the file `src/api/custom/validators.ts` with the following content: - -```ts title="src/api/custom/validators.ts" -import { z } from "zod" - -export const PostStoreCustomSchema = z.object({ - a: z.preprocess( - (val) => { - if (val && typeof val === "string") { - return parseInt(val) - } - return val - }, - z - .number() - ), - b: z.preprocess( - (val) => { - if (val && typeof val === "string") { - return parseInt(val) - } - return val - }, - z - .number() - ), -}) -``` - -Since a query parameter's type is originally a string or array of strings, you have to use Zod's `preprocess` method to validate other query types, such as numbers. - -For both `a` and `b`, you transform the query parameter's value to an integer first if it's a string, then, you check that the resulting value is a number. - -### Step 2: Add Request Query Validation Middleware - -Next, you'll use the schema to validate incoming requests' query parameters to the `/custom` API route. - -Add the `validateAndTransformQuery` middleware to the API route in the file `src/api/middlewares.ts`: - -```ts title="src/api/middlewares.ts" -import { - validateAndTransformQuery, - defineMiddlewares, -} from "@medusajs/framework/http" -import { PostStoreCustomSchema } from "./custom/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom", - method: "POST", - middlewares: [ - validateAndTransformQuery( - PostStoreCustomSchema, - {} - ), - ], - }, - ], -}) -``` - -The `validateAndTransformQuery` accepts two parameters: - -- The first one is the Zod schema to validate the query parameters against. -- The second one is an object of options for retrieving data using Query, which you can learn more about in [this chapter](https://docs.medusajs.com/learn/fundamentals/module-links/query/index.html.md). - -#### How the Validation Works - -If a request's query parameters don't pass the validation, the `validateAndTransformQuery` middleware throws an error indicating the validation errors. - -If a request's query parameters are validated successfully, the middleware sets the validated query parameters in the `validatedQuery` property of `MedusaRequest`. - -### Step 3: Use Validated Query in API Route - -Finally, use the validated query in the API route. The `MedusaRequest` parameter has a `validatedQuery` parameter that you can use to access the validated parameters. - -For example, create the file `src/api/custom/route.ts` with the following content: - -```ts title="src/api/custom/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const a = req.validatedQuery.a as number - const b = req.validatedQuery.b as number - - res.json({ - sum: a + b, - }) -} -``` - -In the API route, you use the `validatedQuery` property of `MedusaRequest` to access the values of the `a` and `b` properties as numbers, then return in the response their sum. - -### Test it Out - -To test out the validation, send a `POST` request to `/custom` with `a` and `b` query parameters. You can try sending incorrect query parameters to see how the validation works. - -For example, if you omit the `a` parameter, you'll receive a `400` response code with the following response data: - -```json -{ - "type": "invalid_data", - "message": "Invalid request: Field 'a' is required" -} -``` - -*** - -## Learn More About Validation Schemas - -To see different examples and learn more about creating a validation schema, refer to [Zod's documentation](https://zod.dev). - - -# Retrieve Custom Links from Medusa's API Route - -In this chapter, you'll learn how to retrieve custom data models linked to existing Medusa data models from Medusa's API routes. - -## Why Retrieve Custom Linked Data Models? - -Often, you'll link custom data models to existing Medusa data models to implement custom features or expand on existing ones. - -For example, to add brands for products, you can create a `Brand` data model in a Brand Module, then [define a link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) to the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md)'s `Product` data model. - -When you implement this customization, you might need to retrieve the brand of a product using the existing [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid). You can do this by passing the linked data model's name in the `fields` query parameter of the API route. - -*** - -## How to Retrieve Custom Linked Data Models Using `fields`? - -Most of Medusa's API routes accept a `fields` query parameter that allows you to specify the fields and relations to retrieve in the resource, such as a product. - -For example, to retrieve the brand of a product, you can pass the `brand` field in the `fields` query parameter of the [Get Product API Route](https://docs.medusajs.com/api/admin#products_getproductsid): - -```bash -curl 'http://localhost:9000/admin/products/{id}?fields=*brand' \ --H 'Authorization: Bearer {access_token}' -``` - -The `fields` query parameter accepts a comma-separated list of fields and relations to retrieve. To learn more about using the `fields` query parameter, refer to the [API Reference](https://docs.medusajs.com/api/store#select-fields-and-relations). - -By prefixing `brand` with an asterisk (`*`), you retrieve all the default fields of the product, including the `brand` field. If you don't include the `*` prefix, the response will only include the product's brand. - -*** - -## API Routes that Restrict Retrievable Fields - -Some of Medusa's API routes restrict the fields and relations you can retrieve, which means you can't pass your custom linked data models in the `fields` query parameter. Medusa makes this restriction to ensure the API routes are performant and secure. - -The API routes that restrict the fields and relations you can retrieve are: - -- [Customer Store API Routes](https://docs.medusajs.com/api/store#customers) -- [Customer Admin API Routes](https://docs.medusajs.com/api/admin#customers) -- [Product Category Admin API Routes](https://docs.medusajs.com/api/admin#product-categories) - -### How to Override Allowed Fields and Relations - -For these routes, you need to override the allowed fields and relations to be retrieved. You can do this by adding a [middleware](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md) to those routes. - -For example, to allow retrieving the `b2b_company` of a customer using the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid), create the file `src/api/middlewares.ts` with the following content: - -Learn how to create a middleware in the [Middlewares](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md) chapter. - -```ts title="src/api/middlewares.ts" highlights={highlights} -import { defineMiddlewares } from "@medusajs/medusa" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/customers/me", - method: "GET", - middlewares: [ - (req, res, next) => { - req.allowed?.push("b2b_company") - next() - }, - ], - }, - ], -}) -``` - -In this example, you apply a middleware to the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid). - -The request object passed to middlewares has an `allowed` property that contains the fields and relations that can be retrieved. So, you modify the `allowed` array to include the `b2b_company` field. - -You can now retrieve the `b2b_company` field using the `fields` query parameter of the [Get Customer Admin API Route](https://docs.medusajs.com/api/admin#customers_getcustomersid): - -```bash -curl 'http://localhost:9000/admin/customers/{id}?fields=*b2b_company' \ --H 'Authorization: Bearer {access_token}' -``` - -In this example, you retrieve the `b2b_company` relation of the customer using the `fields` query parameter. - - -# 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.

Prepare Plugin -### Extend Data Models +### Package Name -If you're adding a link to a data model to extend it and add new fields, define the link from the main data model to the custom data model. +Before developing, testing, and publishing your plugin, make sure its name in `package.json` is correct. This is the name you'll use to install the plugin in your Medusa application. -For example, consider you want to add a `subtitle` custom field to the `product` data model. To do that, you define a `Subtitle` data model in your module, then define a link from the `Product` data model to it: +For example: + +```json title="package.json" +{ + "name": "@myorg/plugin-name", + // ... +} +``` + +### Package Keywords + +Medusa scrapes NPM for a list of plugins that integrate third-party services, to later showcase them on the Medusa website. If you want your plugin to appear in that listing, make sure to add the `medusa-v2` and `medusa-plugin-integration` keywords to the `keywords` field in `package.json`. + +Only plugins that integrate third-party services are listed in the Medusa integrations page.

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 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.

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.

Its value is an array of the workflow's hooks. + +### How to Consume the Hook? + +To consume the hook of the workflow, create the file `src/workflows/hooks/my-workflow.ts` with the following content: + +```ts title="src/workflows/hooks/my-workflow.ts" highlights={handlerHighlights} +import { myWorkflow } from "../my-workflow" + +myWorkflow.hooks.productCreated( + async ({ productId }, { container }) => { + // TODO perform an action + } +) +``` + +The hook is available on the workflow's `hooks` property using its name `productCreated`. + +You invoke the hook, passing a step function (the hook handler) as a parameter. + + +# Conditions in Workflows with When-Then + +In this chapter, you'll learn how to execute an action based on a condition in a workflow using when-then from the Workflows SDK. + +## Why If-Conditions Aren't Allowed in Workflows? + +Medusa creates an internal representation of the workflow definition you pass to `createWorkflow` to track and store its steps. At that point, variables in the workflow don't have any values. They only do when you execute the workflow. + +So, you can't use an if-condition that checks a variable's value, as the condition will be evaluated when Medusa creates the internal representation of the workflow, rather than during execution. + +Instead, use when-then from the Workflows SDK. It allows you to perform steps in a workflow only if a condition that you specify is satisfied. + +Restrictions for conditions is only applicable in a workflow's definition. You can still use if-conditions in your step's code. + +*** + +## How to use When-Then? + +The Workflows SDK provides a `when` function that is used to check whether a condition is true. You chain a `then` function to `when` that specifies the steps to execute if the condition in `when` is satisfied. + +For example: + +```ts highlights={highlights} +import { + createWorkflow, + WorkflowResponse, + when, +} from "@medusajs/framework/workflows-sdk" +// step imports... + +const workflow = createWorkflow( + "workflow", + function (input: { + is_active: boolean + }) { + + const result = when( + input, + (input) => { + return input.is_active + } + ).then(() => { + const stepResult = isActiveStep() + return stepResult + }) + + // executed without condition + const anotherStepResult = anotherStep(result) + + return new WorkflowResponse( + anotherStepResult + ) + } +) +``` + +In this code snippet, you execute the `isActiveStep` only if the `input.is_active`'s value is `true`. + +### When Parameters + +`when` accepts the following parameters: + +1. The first parameter is either an object or the workflow's input. This data is passed as a parameter to the function in `when`'s second parameter. +2. The second parameter is a function that returns a boolean indicating whether to execute the action in `then`. + +### Then Parameters + +To specify the action to perform if the condition is satisfied, chain a `then` function to `when` and pass it a callback function. + +The callback function is only executed if `when`'s second parameter function returns a `true` value. + +*** + +## Implementing If-Else with When-Then + +when-then doesn't support if-else conditions. Instead, use two `when-then` conditions in your workflow. + +For example: + +```ts highlights={ifElseHighlights} +const workflow = createWorkflow( + "workflow", + function (input: { + is_active: boolean + }) { + + const isActiveResult = when( + input, + (input) => { + return input.is_active + } + ).then(() => { + return isActiveStep() + }) + + const notIsActiveResult = when( + input, + (input) => { + return !input.is_active + } + ).then(() => { + return notIsActiveStep() + }) + + // ... + } +) +``` + +In the above workflow, you use two `when-then` blocks. The first one performs a step if `input.is_active` is `true`, and the second performs a step if `input.is_active` is `false`, acting as an else condition. + +*** + +## Specify Name for When-Then + +Internally, `when-then` blocks have a unique name similar to a step. When you return a step's result in a `when-then` block, the block's name is derived from the step's name. For example: + +```ts +const isActiveResult = when( + input, + (input) => { + return input.is_active + } +).then(() => { + return isActiveStep() +}) +``` + +This `when-then` block's internal name will be `when-then-is-active`, where `is-active` is the step's name. + +However, if you need to return in your `when-then` block something other than a step's result, you need to specify a unique step name for that block. Otherwise, Medusa will generate a random name for it which can cause unexpected errors in production. + +You pass a name for `when-then` as a first parameter of `when`, whose signature can accept three parameters in this case. For example: + +```ts highlights={nameHighlights} +const { isActive } = when( + "check-is-active", + input, + (input) => { + return input.is_active + } +).then(() => { + const isActive = isActiveStep() + + return { + isActive, + } +}) +``` + +Since `then` returns a value different than the step's result, you pass to the `when` function the following parameters: + +1. A unique name to be assigned to the `when-then` block. +2. Either an object or the workflow's input. This data is passed as a parameter to the function in `when`'s second parameter. +3. A function that returns a boolean indicating whether to execute the action in `then`. + +The second and third parameters are the same as the parameters you previously passed to `when`. + # Error Handling in Workflows @@ -16267,79 +15712,359 @@ const workflow = createWorkflow( In this example, you use when-then to run the `createProductsWorkflow` only if `should_create` (passed in the `input`) is enabled. -# Multiple Step Usage in Workflow +# Workflow Constraints -In this chapter, you'll learn how to use a step multiple times in a workflow. +This chapter lists constraints of defining a workflow or its steps. -## Problem Reusing a Step in a Workflow +Medusa creates an internal representation of the workflow definition you pass to `createWorkflow` to track and store its steps.

When a user is registered using an authentication provider, the provider creates a record of `AuthIdentity`. - -Then, when the user logs-in in the future with the same authentication provider, the associated auth identity is used to validate their credentials. - -*** - -## Actor Types - -An actor type is a type of user that can be authenticated. The Auth Module doesn't store or manage any user-like models, such as for customers or users. Instead, the user types are created and managed by other modules. For example, a customer is managed by the [Customer Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/customer/index.html.md). - -Then, when an auth identity is created for the actor type, the ID of the user is stored in the `app_metadata` property of the auth identity. - -For example, an auth identity of a customer has the following `app_metadata` property: - -```json -{ - "app_metadata": { - "customer_id": "cus_123" - } -} -``` - -The ID of the user is stored in the key `{actor_type}_id` of the `app_metadata` property. - -*** - -## Protect Routes by Actor Type - -When you protect routes with the `authenticate` middleware, you specify in its first parameter the actor type that must be authenticated to access the specified API routes. - -For example: - -```ts title="src/api/middlewares.ts" highlights={highlights} -import { - defineMiddlewares, - authenticate, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/custom/admin*", - middlewares: [ - authenticate("user", ["session", "bearer", "api-key"]), - ], - }, +const { data: customers } = await query.graph({ + entity: "customer", + fields: [ + "account_holder_link.account_holder.*", ], }) + +// customers[0].account_holder_link?.[0]?.account_holder ``` -By specifying `user` as the first parameter of `authenticate`, only authenticated users of actor type `user` (admin users) can access API routes starting with `/custom/admin`. +### useQueryGraphStep -*** +```ts +import { useQueryGraphStep } from "@medusajs/medusa/core-flows" -## Custom Actor Types +// ... -You can define custom actor types that allows a custom user, managed by your custom module, to authenticate into Medusa. +const { data: customers } = useQueryGraphStep({ + entity: "customer", + fields: [ + "account_holder_link.account_holder.*", + ], +}) -For example, if you have a custom module with a `Manager` data model, you can authenticate managers with the `manager` actor type. +// customers[0].account_holder_link?.[0]?.account_holder +``` -Learn how to create a custom actor type in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/create-actor-type/index.html.md). +### Manage with Link +To manage the account holders of a customer, use [Link](https://docs.medusajs.com/docs/learn/fundamentals/module-links/link/index.html.md): -# Auth Providers +### link.create -In this document, you’ll learn how the Auth Module handles authentication using providers. +```ts +import { Modules } from "@medusajs/framework/utils" -## What's an Auth Module Provider? +// ... -An auth module provider handles authenticating customers and users, either using custom logic or by integrating a third-party service. - -For example, the EmailPass Auth Module Provider authenticates a user using their email and password, whereas the Google Auth Module Provider authenticates users using their Google account. - -### Auth Providers List - -- [Emailpass](https://docs.medusajs.com/commerce-modules/auth/auth-providers/emailpass/index.html.md) -- [Google](https://docs.medusajs.com/commerce-modules/auth/auth-providers/google/index.html.md) -- [GitHub](https://docs.medusajs.com/commerce-modules/auth/auth-providers/github/index.html.md) - -*** - -## Configure Allowed Auth Providers of Actor Types - -By default, users of all actor types can authenticate with all installed auth module providers. - -To restrict the auth providers used for actor types, use the [authMethodsPerActor option](https://docs.medusajs.com/docs/learn/configurations/medusa-config#httpauthMethodsPerActor/index.html.md) in Medusa's configurations: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - http: { - authMethodsPerActor: { - user: ["google"], - customer: ["emailpass"], - }, - // ... - }, - // ... +await link.create({ + [Modules.CUSTOMER]: { + customer_id: "cus_123", + }, + [Modules.PAYMENT]: { + account_holder_id: "acchld_123", }, }) ``` -When you specify the `authMethodsPerActor` configuration, it overrides the default.

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 returns a JWT token that can be passed in [the header of subsequent requests](https://docs.medusajs.com/api/store#authentication) to send authenticated requests. - -```bash -curl -X POST http://localhost:9000/auth/{actor_type}/{providers} --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "Whitney_Schultz@gmail.com" - // ... -}' -``` - -For example, if you're authenticating a customer, you send a request to `/auth/customer/emailpass`. - -### 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. - -#### Overriding Callback URL - -For the [GitHub](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-providers/github/index.html.md) and [Google](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-providers/google/index.html.md) providers, you can pass a `callback_url` body parameter that overrides the `callbackUrl` set in the provider's configurations. - -This is useful if you want to redirect the user to a different URL after authentication based on their actor type. For example, you can set different `callback_url` for admin users and customers. - -### 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. - -If the authentication requires more action with a third-party service, you'll receive a `location` property: - -```json -{ - "location": "https://..." -} -``` - -Redirect to that URL in the frontend to continue the authentication process with the third-party service. - -[How to login Customers using the authentication route](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/storefront-development/customers/login/index.html.md). - -*** - -## Validate Callback Route - -The Medusa application defines an API route at `/auth/{actor_type}/{provider}/callback` that's useful for validating the authentication callback or redirect from third-party services like Google. - -```bash -curl -X POST http://localhost:9000/auth/{actor_type}/{providers}/callback?code=123&state=456 -``` - -Refer to the [third-party authentication flow](#2-third-party-service-authenticate-flow) section to see how this route fits into the authentication flow. - -### Path Parameters - -Its path parameters are: - -- `{actor_type}`: the actor type of the user you're authenticating.

For example, `emailpass`. - -#### Pass Token in Authorization Header - -Before [Medusa v2.6](https://github.com/medusajs/medusa/releases/tag/v2.6), you passed the token as a query parameter. Now, you must pass it in the `Authorization` header. - -In the request's authorization header, you must pass the token generated using the [Generate Reset Password Token route](#generate-reset-password-token-route). You pass it as a bearer token. - -### Request Body Parameters - -This route accepts in the request body an object that has the data necessary for the provider to update the user's password. - -For the `emailpass` provider, you must pass the following properties: - -- `email`: The user's email. -- `password`: The new password. - -### Response Fields - -If the authentication is successful, the request returns an object with a `success` property set to `true`: - -```json -{ - "success": "true" -} -``` - - -# How to Create an Actor Type - -In this document, learn how to create an actor type and authenticate its associated data model. - -## 0. Create Module with Data Model - -Before creating an actor type, you must have a module with a data model representing the actor type. - -Learn how to create a module in [this guide](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). - -The rest of this guide uses this `Manager` data model as an example: - -```ts title="src/modules/manager/models/manager.ts" -import { model } from "@medusajs/framework/utils" - -const Manager = model.define("manager", { - id: model.id().primaryKey(), - firstName: model.text(), - lastName: model.text(), - email: model.text(), -}) - -export default Manager -``` - -*** - -## 1. Create Workflow - -Start by creating a workflow that does two things: - -- Creates a record of the `Manager` data model. -- Sets the `app_metadata` property of the associated `AuthIdentity` record based on the new actor type. - -For example, create the file `src/workflows/create-manager.ts`. with the following content: - -```ts title="src/workflows/create-manager.ts" highlights={workflowHighlights} -import { - createWorkflow, - createStep, - StepResponse, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - setAuthAppMetadataStep, -} from "@medusajs/medusa/core-flows" -import ManagerModuleService from "../modules/manager/service" - -type CreateManagerWorkflowInput = { - manager: { - first_name: string - last_name: string - email: string - } - authIdentityId: string -} - -const createManagerStep = createStep( - "create-manager-step", - async ({ - manager: managerData, - }: Pick, - { container }) => { - const managerModuleService: ManagerModuleService = - container.resolve("managerModuleService") - - const manager = await managerModuleService.createManager( - managerData - ) - - return new StepResponse(manager) - } -) - -const createManagerWorkflow = createWorkflow( - "create-manager", - function (input: CreateManagerWorkflowInput) { - const manager = createManagerStep({ - manager: input.manager, - }) - - setAuthAppMetadataStep({ - authIdentityId: input.authIdentityId, - actorType: "manager", - value: manager.id, - }) - - return new WorkflowResponse(manager) - } -) - -export default createManagerWorkflow -``` - -This workflow accepts the manager’s data and the associated auth identity’s ID as inputs. The next sections explain how the auth identity ID is retrieved. - -The workflow has two steps: - -1. Create the manager using the `createManagerStep`. -2. Set the `app_metadata` property of the associated auth identity using the `setAuthAppMetadataStep` from Medusa's core workflows. You specify the actor type `manager` in the `actorType` property of the step’s input. - -*** - -## 2. Define the Create API Route - -Next, you’ll use the workflow defined in the previous section in an API route that creates a manager. - -So, create the file `src/api/manager/route.ts` with the following content: - -```ts title="src/api/manager/route.ts" highlights={createRouteHighlights} -import type { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { MedusaError } from "@medusajs/framework/utils" -import createManagerWorkflow from "../../workflows/create-manager" - -type RequestBody = { - first_name: string - last_name: string - email: string -} - -export async function POST( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) { - // If `actor_id` is present, the request carries - // authentication for an existing manager - if (req.auth_context.actor_id) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Request already authenticated as a manager." - ) - } - - const { result } = await createManagerWorkflow(req.scope) - .run({ - input: { - manager: req.body, - authIdentityId: req.auth_context.auth_identity_id, - }, - }) - - res.status(200).json({ manager: result }) -} -``` - -Since the manager must be associated with an `AuthIdentity` record, the request is expected to be authenticated, even if the manager isn’t created yet. This can be achieved by: - -1. Obtaining a token usng the [/auth route](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/authentication-route/index.html.md). -2. Passing the token in the bearer header of the request to this route. - -In the API route, you create the manager using the workflow from the previous section and return it in the response. - -*** - -## 3. Apply the `authenticate` Middleware - -The last step is to apply the `authenticate` middleware on the API routes that require a manager’s authentication. - -To do that, create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" highlights={middlewareHighlights} -import { - defineMiddlewares, - authenticate, -} from "@medusajs/framework/http" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/manager", - method: "POST", - middlewares: [ - authenticate("manager", ["session", "bearer"], { - allowUnregistered: true, - }), - ], - }, - { - matcher: "/manager/me*", - middlewares: [ - authenticate("manager", ["session", "bearer"]), - ], - }, - ], -}) -``` - -This applies middlewares on two route patterns: - -1. The `authenticate` middleware is applied on the `/manager` API route for `POST` requests while allowing unregistered managers. This requires that a bearer token be passed in the request to access the manager’s auth identity but doesn’t require the manager to be registered. -2. The `authenticate` middleware is applied on all routes starting with `/manager/me`, restricting these routes to authenticated managers only. - -### Retrieve Manager API Route - -For example, create the file `src/api/manager/me/route.ts` with the following content: - -```ts title="src/api/manager/me/route.ts" -import { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import ManagerModuleService from "../../../modules/manager/service" - -export async function GET( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -): Promise { - const managerModuleService: ManagerModuleService = - req.scope.resolve("managerModuleService") - - const manager = await managerModuleService.retrieveManager( - req.auth_context.actor_id - ) - - res.json({ manager }) -} -``` - -This route is only accessible by authenticated managers. You access the manager’s ID using `req.auth_context.actor_id`. - -*** - -## Test Custom Actor Type Authentication Flow - -To authenticate managers: - -1. Send a `POST` request to `/auth/manager/emailpass/register` to create an auth identity for the manager: - -```bash -curl -X POST 'http://localhost:9000/auth/manager/emailpass/register' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "manager@gmail.com", - "password": "supersecret" -}' -``` - -Copy the returned token to use it in the next request. - -2. Send a `POST` request to `/manager` to create a manager: - -```bash -curl -X POST 'http://localhost:9000/manager' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data-raw '{ - "first_name": "John", - "last_name": "Doe", - "email": "manager@gmail.com" -}' -``` - -Replace `{token}` with the token returned in the previous step. - -3. Send a `POST` request to `/auth/manager/emailpass` again to retrieve an authenticated token for the manager: - -```bash -curl -X POST 'http://localhost:9000/auth/manager/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "manager@gmail.com", - "password": "supersecret" -}' -``` - -4. You can now send authenticated requests as a manager. For example, send a `GET` request to `/manager/me` to retrieve the authenticated manager’s details: - -```bash -curl 'http://localhost:9000/manager/me' \ --H 'Authorization: Bearer {token}' -``` - -Whenever you want to log in as a manager, use the `/auth/manager/emailpass` API route, as explained in step 3. - -*** - -## Delete User of Actor Type - -When you delete a user of the actor type, you must update its auth identity to remove the association to the user. - -For example, create the following workflow that deletes a manager and updates its auth identity, create the file `src/workflows/delete-manager.ts` with the following content: - -```ts title="src/workflows/delete-manager.ts" collapsibleLines="1-6" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import ManagerModuleService from "../modules/manager/service" - -export type DeleteManagerWorkflow = { - id: string -} - -const deleteManagerStep = createStep( - "delete-manager-step", - async ( - { id }: DeleteManagerWorkflow, - { container }) => { - const managerModuleService: ManagerModuleService = - container.resolve("managerModuleService") - - const manager = await managerModuleService.retrieve(id) - - await managerModuleService.deleteManagers(id) - - return new StepResponse(undefined, { manager }) - }, - async ({ manager }, { container }) => { - const managerModuleService: ManagerModuleService = - container.resolve("managerModuleService") - - await managerModuleService.createManagers(manager) - } - ) -``` - -You add a step that deletes the manager using the `deleteManagers` method of the module's main service. In the compensation function, you create the manager again. - -Next, in the same file, add the workflow that deletes a manager: - -```ts title="src/workflows/delete-manager.ts" collapsibleLines="1-15" expandButtonLabel="Show Imports" highlights={deleteHighlights} -// other imports -import { MedusaError } from "@medusajs/framework/utils" -import { - WorkflowData, - WorkflowResponse, - createWorkflow, - transform, -} from "@medusajs/framework/workflows-sdk" -import { - setAuthAppMetadataStep, - useQueryGraphStep, -} from "@medusajs/medusa/core-flows" +```ts +import { createRemoteLinkStep } from "@medusajs/medusa/core-flows" // ... -export const deleteManagerWorkflow = createWorkflow( - "delete-manager", - ( - input: WorkflowData - ): WorkflowResponse => { - deleteManagerStep(input) - - const { data: authIdentities } = useQueryGraphStep({ - entity: "auth_identity", - fields: ["id"], - filters: { - app_metadata: { - // the ID is of the format `{actor_type}_id`. - manager_id: input.id, - }, - }, - }) - - const authIdentity = transform( - { authIdentities }, - ({ authIdentities }) => { - const authIdentity = authIdentities[0] - - if (!authIdentity) { - throw new MedusaError( - MedusaError.Types.NOT_FOUND, - "Auth identity not found" - ) - } - - return authIdentity - } - ) - - setAuthAppMetadataStep({ - authIdentityId: authIdentity.id, - actorType: "manager", - value: null, - }) - - return new WorkflowResponse(input.id) - } -) -``` - -In the workflow, you: - -1. Use the `deleteManagerStep` defined earlier to delete the manager. -2. Retrieve the auth identity of the manager using Query. To do that, you filter the `app_metadata` property of an auth identity, which holds the user's ID under `{actor_type_name}_id`. So, in this case, it's `manager_id`. -3. Check that the auth identity exist, then, update the auth identity to remove the ID of the manager from it. - -You can use this workflow when deleting a manager, such as in an API route. - - -# Auth Module Options - -In this document, you'll learn about the options of the Auth Module. - -## providers - -The `providers` option is an array of auth module providers. - -When the Medusa application starts, these providers are registered and can be used to handle authentication. - -By default, the `emailpass` provider is registered to authenticate customers and admin users. - -For example: - -```ts title="medusa-config.ts" -import { Modules, ContainerRegistrationKeys } from "@medusajs/framework/utils" - -// ... - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/auth", - dependencies: [Modules.CACHE, ContainerRegistrationKeys.LOGGER], - options: { - providers: [ - { - resolve: "@medusajs/medusa/auth-emailpass", - id: "emailpass", - options: { - // provider options... - }, - }, - ], - }, - }, - ], +createRemoteLinkStep({ + [Modules.CUSTOMER]: { + customer_id: "cus_123", + }, + [Modules.PAYMENT]: { + account_holder_id: "acchld_123", + }, }) ``` -The `providers` option is an array of objects that accept the following properties: - -- `resolve`: A string indicating the package name of the module provider or the path to it relative to the `src` directory. -- `id`: A string indicating the provider's unique name or ID. -- `options`: An optional object of the module provider's options. - *** -## Auth CORS +## Cart Module -The Medusa application's authentication API routes are defined under the `/auth` prefix that requires setting the `authCors` property of the `http` configuration. +Medusa defines a read-only link between the [Cart Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/cart/index.html.md)'s `Cart` data model and the `Customer` data model.

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`.

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.

For example: + +```ts +const data = await authModuleService.authenticate( + "emailpass", + // passed to auth provider + { + // ... + } +) +``` + +This method calls the `authenticate` method of the provider specified in the first parameter and returns its data. + +*** + +## Auth Flow 1: Basic Authentication + +The basic authentication flow requires first using the `register` method, then the `authenticate` method: + +```ts +const { success, authIdentity, error } = await authModuleService.register( + "emailpass", + // passed to auth provider + { + // ... + } +) + +if (error) { + // registration failed + // TODO return an error + return +} + +// later (can be another route for log-in) +const { success, authIdentity, location } = await authModuleService.authenticate( + "emailpass", + // passed to auth provider + { + // ... + } +) + +if (success && !location) { + // user is authenticated +} +``` + +If `success` is true and `location` isn't set, the user is authenticated successfully, and their authentication details are available within the `authIdentity` object. + +The next section explains the flow if `location` is set. + +Check out the [AuthIdentity](https://docs.medusajs.com/references/auth/models/AuthIdentity/index.html.md) reference for the received properties in `authIdentity`. + +![Diagram showcasing the basic authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1711373749/Medusa%20Resources/basic-auth_lgpqsj.jpg) + +### Auth Identity with Same Identifier + +If an auth identity, such as a `customer`, tries to register with an email of another auth identity, the `register` method returns an error. This can happen either if another customer is using the same email, or an admin user has the same email. + +There are two ways to handle this: + +- Consider the customer authenticated if the `authenticate` method validates that the email and password are correct. This allows admin users, for example, to authenticate as customers. +- Return an error message to the customer, informing them that the email is already in use. + +*** + +## Auth Flow 2: Third-Party Service Authentication + +The third-party service authentication method requires using the `authenticate` method first: + +```ts +const { success, authIdentity, location } = await authModuleService.authenticate( + "google", + // passed to auth provider + { + // ... + } +) + +if (location) { + // return the location for the front-end to redirect to +} + +if (!success) { + // authentication failed +} + +// authentication successful +``` + +If the `authenticate` method returns a `location` property, the authentication process requires the user to perform an action with a third-party service. So, you return the `location` to the front-end or client to redirect to that URL. + +For example, when using the `google` provider, the `location` is the URL that the user is navigated to login. + +![Diagram showcasing the first part of the third-party authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1711374847/Medusa%20Resources/third-party-auth-1_enyedy.jpg) + +### Overriding Callback URL + +The Google and GitHub providers allow you to override their `callbackUrl` option during authentication. This is useful when you redirect the user after authentication to a URL based on its actor type. For example, you redirect admin users and customers to different pages. + +```ts +const { success, authIdentity, location } = await authModuleService.authenticate( + "google", + // passed to auth provider + { + // ... + callback_url: "example.com", + } +) +``` + +### validateCallback + +Providers handling this authentication flow must implement the `validateCallback` method. It implements the logic to validate the authentication with the third-party service. + +So, once the user performs the required action with the third-party service (for example, log-in with Google), the frontend must redirect to an API route that uses the [validateCallback method of the Auth Module's main service](https://docs.medusajs.com/references/auth/validateCallback/index.html.md). + +The method calls the specified provider’s `validateCallback` method passing it the authentication details it received in the second parameter: + +```ts +const { success, authIdentity } = await authModuleService.validateCallback( + "google", + // passed to auth provider + { + // request data, such as + url, + headers, + query, + body, + protocol, + } +) + +if (success) { + // authentication succeeded +} +``` + +For providers like Google, the `query` object contains the query parameters from the original callback URL, such as the `code` and `state` parameters. + +If the returned `success` property is `true`, the authentication with the third-party provider was successful. + +![Diagram showcasing the second part of the third-party authentication flow](https://res.cloudinary.com/dza7lstvk/image/upload/v1711375123/Medusa%20Resources/third-party-auth-2_kmjxju.jpg) + +*** + +## Reset Password + +To update a user's password or other authentication details, use the `updateProvider` method of the Auth Module's main service. It calls the `update` method of the specified authentication provider. + +For example: + +```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 Create an Actor Type + +In this document, learn how to create an actor type and authenticate its associated data model. + +## 0. Create Module with Data Model + +Before creating an actor type, you must have a module with a data model representing the actor type. + +Learn how to create a module in [this guide](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). + +The rest of this guide uses this `Manager` data model as an example: + +```ts title="src/modules/manager/models/manager.ts" +import { model } from "@medusajs/framework/utils" + +const Manager = model.define("manager", { + id: model.id().primaryKey(), + firstName: model.text(), + lastName: model.text(), + email: model.text(), +}) + +export default Manager +``` + +*** + +## 1. Create Workflow + +Start by creating a workflow that does two things: + +- Creates a record of the `Manager` data model. +- Sets the `app_metadata` property of the associated `AuthIdentity` record based on the new actor type. + +For example, create the file `src/workflows/create-manager.ts`. with the following content: + +```ts title="src/workflows/create-manager.ts" highlights={workflowHighlights} +import { + createWorkflow, + createStep, + StepResponse, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" +import { + setAuthAppMetadataStep, +} from "@medusajs/medusa/core-flows" +import ManagerModuleService from "../modules/manager/service" + +type CreateManagerWorkflowInput = { + manager: { + first_name: string + last_name: string + email: string + } + authIdentityId: string +} + +const createManagerStep = createStep( + "create-manager-step", + async ({ + manager: managerData, + }: Pick, + { container }) => { + const managerModuleService: ManagerModuleService = + container.resolve("managerModuleService") + + const manager = await managerModuleService.createManager( + managerData + ) + + return new StepResponse(manager) + } +) + +const createManagerWorkflow = createWorkflow( + "create-manager", + function (input: CreateManagerWorkflowInput) { + const manager = createManagerStep({ + manager: input.manager, + }) + + setAuthAppMetadataStep({ + authIdentityId: input.authIdentityId, + actorType: "manager", + value: manager.id, + }) + + return new WorkflowResponse(manager) + } +) + +export default createManagerWorkflow +``` + +This workflow accepts the manager’s data and the associated auth identity’s ID as inputs. The next sections explain how the auth identity ID is retrieved. + +The workflow has two steps: + +1. Create the manager using the `createManagerStep`. +2. Set the `app_metadata` property of the associated auth identity using the `setAuthAppMetadataStep` from Medusa's core workflows. You specify the actor type `manager` in the `actorType` property of the step’s input. + +*** + +## 2. Define the Create API Route + +Next, you’ll use the workflow defined in the previous section in an API route that creates a manager. + +So, create the file `src/api/manager/route.ts` with the following content: + +```ts title="src/api/manager/route.ts" highlights={createRouteHighlights} +import type { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { MedusaError } from "@medusajs/framework/utils" +import createManagerWorkflow from "../../workflows/create-manager" + +type RequestBody = { + first_name: string + last_name: string + email: string +} + +export async function POST( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) { + // If `actor_id` is present, the request carries + // authentication for an existing manager + if (req.auth_context.actor_id) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Request already authenticated as a manager." + ) + } + + const { result } = await createManagerWorkflow(req.scope) + .run({ + input: { + manager: req.body, + authIdentityId: req.auth_context.auth_identity_id, + }, + }) + + res.status(200).json({ manager: result }) +} +``` + +Since the manager must be associated with an `AuthIdentity` record, the request is expected to be authenticated, even if the manager isn’t created yet. This can be achieved by: + +1. Obtaining a token usng the [/auth route](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/authentication-route/index.html.md). +2. Passing the token in the bearer header of the request to this route. + +In the API route, you create the manager using the workflow from the previous section and return it in the response. + +*** + +## 3. Apply the `authenticate` Middleware + +The last step is to apply the `authenticate` middleware on the API routes that require a manager’s authentication. + +To do that, create the file `src/api/middlewares.ts` with the following content: + +```ts title="src/api/middlewares.ts" highlights={middlewareHighlights} +import { + defineMiddlewares, + authenticate, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/manager", + method: "POST", + middlewares: [ + authenticate("manager", ["session", "bearer"], { + allowUnregistered: true, + }), + ], + }, + { + matcher: "/manager/me*", + middlewares: [ + authenticate("manager", ["session", "bearer"]), + ], + }, + ], +}) +``` + +This applies middlewares on two route patterns: + +1. The `authenticate` middleware is applied on the `/manager` API route for `POST` requests while allowing unregistered managers. This requires that a bearer token be passed in the request to access the manager’s auth identity but doesn’t require the manager to be registered. +2. The `authenticate` middleware is applied on all routes starting with `/manager/me`, restricting these routes to authenticated managers only. + +### Retrieve Manager API Route + +For example, create the file `src/api/manager/me/route.ts` with the following content: + +```ts title="src/api/manager/me/route.ts" +import { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import ManagerModuleService from "../../../modules/manager/service" + +export async function GET( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +): Promise { + const managerModuleService: ManagerModuleService = + req.scope.resolve("managerModuleService") + + const manager = await managerModuleService.retrieveManager( + req.auth_context.actor_id + ) + + res.json({ manager }) +} +``` + +This route is only accessible by authenticated managers. You access the manager’s ID using `req.auth_context.actor_id`. + +*** + +## Test Custom Actor Type Authentication Flow + +To authenticate managers: + +1. Send a `POST` request to `/auth/manager/emailpass/register` to create an auth identity for the manager: + +```bash +curl -X POST 'http://localhost:9000/auth/manager/emailpass/register' \ +-H 'Content-Type: application/json' \ +--data-raw '{ + "email": "manager@gmail.com", + "password": "supersecret" +}' +``` + +Copy the returned token to use it in the next request. + +2. Send a `POST` request to `/manager` to create a manager: + +```bash +curl -X POST 'http://localhost:9000/manager' \ +-H 'Content-Type: application/json' \ +-H 'Authorization: Bearer {token}' \ +--data-raw '{ + "first_name": "John", + "last_name": "Doe", + "email": "manager@gmail.com" +}' +``` + +Replace `{token}` with the token returned in the previous step. + +3. Send a `POST` request to `/auth/manager/emailpass` again to retrieve an authenticated token for the manager: + +```bash +curl -X POST 'http://localhost:9000/auth/manager/emailpass' \ +-H 'Content-Type: application/json' \ +--data-raw '{ + "email": "manager@gmail.com", + "password": "supersecret" +}' +``` + +4. You can now send authenticated requests as a manager. For example, send a `GET` request to `/manager/me` to retrieve the authenticated manager’s details: + +```bash +curl 'http://localhost:9000/manager/me' \ +-H 'Authorization: Bearer {token}' +``` + +Whenever you want to log in as a manager, use the `/auth/manager/emailpass` API route, as explained in step 3. + +*** + +## Delete User of Actor Type + +When you delete a user of the actor type, you must update its auth identity to remove the association to the user. + +For example, create the following workflow that deletes a manager and updates its auth identity, create the file `src/workflows/delete-manager.ts` with the following content: + +```ts title="src/workflows/delete-manager.ts" collapsibleLines="1-6" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import ManagerModuleService from "../modules/manager/service" + +export type DeleteManagerWorkflow = { + id: string +} + +const deleteManagerStep = createStep( + "delete-manager-step", + async ( + { id }: DeleteManagerWorkflow, + { container }) => { + const managerModuleService: ManagerModuleService = + container.resolve("managerModuleService") + + const manager = await managerModuleService.retrieve(id) + + await managerModuleService.deleteManagers(id) + + return new StepResponse(undefined, { manager }) + }, + async ({ manager }, { container }) => { + const managerModuleService: ManagerModuleService = + container.resolve("managerModuleService") + + await managerModuleService.createManagers(manager) + } + ) +``` + +You add a step that deletes the manager using the `deleteManagers` method of the module's main service. In the compensation function, you create the manager again. + +Next, in the same file, add the workflow that deletes a manager: + +```ts title="src/workflows/delete-manager.ts" collapsibleLines="1-15" expandButtonLabel="Show Imports" highlights={deleteHighlights} +// other imports +import { MedusaError } from "@medusajs/framework/utils" +import { + WorkflowData, + WorkflowResponse, + createWorkflow, + transform, +} from "@medusajs/framework/workflows-sdk" +import { + setAuthAppMetadataStep, + useQueryGraphStep, +} from "@medusajs/medusa/core-flows" // ... -const { data: customers } = useQueryGraphStep({ - entity: "customer", - fields: [ - "account_holder_link.account_holder.*", - ], -}) +export const deleteManagerWorkflow = createWorkflow( + "delete-manager", + ( + input: WorkflowData + ): WorkflowResponse => { + deleteManagerStep(input) -// customers[0].account_holder_link?.[0]?.account_holder + const { data: authIdentities } = useQueryGraphStep({ + entity: "auth_identity", + fields: ["id"], + filters: { + app_metadata: { + // the ID is of the format `{actor_type}_id`. + manager_id: input.id, + }, + }, + }) + + const authIdentity = transform( + { authIdentities }, + ({ authIdentities }) => { + const authIdentity = authIdentities[0] + + if (!authIdentity) { + throw new MedusaError( + MedusaError.Types.NOT_FOUND, + "Auth identity not found" + ) + } + + return authIdentity + } + ) + + setAuthAppMetadataStep({ + authIdentityId: authIdentity.id, + actorType: "manager", + value: null, + }) + + return new WorkflowResponse(input.id) + } +) ``` -### Manage with Link +In the workflow, you: -To manage the account holders of a customer, use [Link](https://docs.medusajs.com/docs/learn/fundamentals/module-links/link/index.html.md): +1. Use the `deleteManagerStep` defined earlier to delete the manager. +2. Retrieve the auth identity of the manager using Query. To do that, you filter the `app_metadata` property of an auth identity, which holds the user's ID under `{actor_type_name}_id`. So, in this case, it's `manager_id`. +3. Check that the auth identity exist, then, update the auth identity to remove the ID of the manager from it. -### link.create +You can use this workflow when deleting a manager, such as in an API route. -```ts + +# Auth Identity and Actor Types + +In this document, you’ll learn about concepts related to identity and actors in the Auth Module. + +## What is an Auth Identity? + +The [AuthIdentity data model](https://docs.medusajs.com/references/auth/models/AuthIdentity/index.html.md) represents a user registered by an [authentication provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-providers/index.html.md). When a user is registered using an authentication provider, the provider creates a record of `AuthIdentity`. + +Then, when the user logs-in in the future with the same authentication provider, the associated auth identity is used to validate their credentials. + +*** + +## Actor Types + +An actor type is a type of user that can be authenticated. The Auth Module doesn't store or manage any user-like models, such as for customers or users. Instead, the user types are created and managed by other modules. For example, a customer is managed by the [Customer Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/customer/index.html.md). + +Then, when an auth identity is created for the actor type, the ID of the user is stored in the `app_metadata` property of the auth identity. + +For example, an auth identity of a customer has the following `app_metadata` property: + +```json +{ + "app_metadata": { + "customer_id": "cus_123" + } +} +``` + +The ID of the user is stored in the key `{actor_type}_id` of the `app_metadata` property. + +*** + +## Protect Routes by Actor Type + +When you protect routes with the `authenticate` middleware, you specify in its first parameter the actor type that must be authenticated to access the specified API routes. + +For example: + +```ts title="src/api/middlewares.ts" highlights={highlights} +import { + defineMiddlewares, + authenticate, +} from "@medusajs/framework/http" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/custom/admin*", + middlewares: [ + authenticate("user", ["session", "bearer", "api-key"]), + ], + }, + ], +}) +``` + +By specifying `user` as the first parameter of `authenticate`, only authenticated users of actor type `user` (admin users) can access API routes starting with `/custom/admin`. + +*** + +## Custom Actor Types + +You can define custom actor types that allows a custom user, managed by your custom module, to authenticate into Medusa. + +For example, if you have a custom module with a `Manager` data model, you can authenticate managers with the `manager` actor type. + +Learn how to create a custom actor type in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/create-actor-type/index.html.md). + + +# Auth Module Options + +In this document, you'll learn about the options of the Auth Module. + +## providers + +The `providers` option is an array of auth module providers. + +When the Medusa application starts, these providers are registered and can be used to handle authentication. + +By default, the `emailpass` provider is registered to authenticate customers and admin users. + +For example: + +```ts title="medusa-config.ts" +import { Modules, ContainerRegistrationKeys } from "@medusajs/framework/utils" + +// ... + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/auth", + dependencies: [Modules.CACHE, ContainerRegistrationKeys.LOGGER], + options: { + providers: [ + { + resolve: "@medusajs/medusa/auth-emailpass", + id: "emailpass", + options: { + // provider options... + }, + }, + ], + }, + }, + ], +}) +``` + +The `providers` option is an array of objects that accept the following properties: + +- `resolve`: A string indicating the package name of the module provider or the path to it relative to the `src` directory. +- `id`: A string indicating the provider's unique name or ID. +- `options`: An optional object of the module provider's options. + +*** + +## Auth CORS + +The Medusa application's authentication API routes are defined under the `/auth` prefix that requires setting the `authCors` property of the `http` configuration. + +By default, the Medusa application you created will have an `AUTH_CORS` environment variable, which is used as the value of `authCors`. + +Refer to [Medusa's configuration guide](https://docs.medusajs.com/docs/learn/configurations/medusa-config#httpauthCors/index.html.md) to learn more about the `authCors` configuration. + +*** + +## authMethodsPerActor Configuration + +The Medusa application's configuration accept an `authMethodsPerActor` configuration which restricts the allowed auth providers used with an actor type. + +Learn more about the `authMethodsPerActor` configuration in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/auth-providers#configure-allowed-auth-providers-of-actor-types/index.html.md). + + +# How to Handle Password Reset Token Event + +In this guide, you'll learn how to handle the `auth.password_reset` event, which is emitted when a request is sent to the [Generate Reset Password Token API route](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/auth/authentication-route#generate-reset-password-token-route/index.html.md). + +Refer to this [Medusa Admin User Guide](https://docs.medusajs.com/user-guide/reset-password/index.html.md) to learn how to reset your user admin password using the dashboard. + +You'll create a subscriber that listens to the event.

It indicates the quantity that's still not removed from stock, but considered as unavailable when checking whether an item is in stock. -- `incoming_quantity`: The incoming stock quantity of an item into the associated location. This property doesn't play into the `stocked_quantity` or when checking whether an item is in stock. - -### Associated Location - -The inventory level's location is determined by the `location_id` property. Medusa links the `InventoryLevel` data model with the `StockLocation` data model from the Stock Location Module. - -*** - -## ReservationItem - -A reservation item, represented by the [ReservationItem](https://docs.medusajs.com/references/inventory-next/models/ReservationItem/index.html.md) data model, represents unavailable quantity of an inventory item in a location. It's used when an order is placed but not fulfilled yet. - -The reserved quantity is associated with a location, so it has a similar relation to that of the `InventoryLevel` with the Stock Location Module. - - -# Inventory Kits - -In this guide, you'll learn how inventory kits can be used in the Medusa application to support use cases like multi-part products, bundled products, and shared inventory across products. - -Refer to the following user guides to learn how to use the Medusa Admin dashboard to: - -- [Create Multi-Part Products](https://docs.medusajs.com/user-guide/products/create/multi-part/index.html.md). -- [Create Bundled Products](https://docs.medusajs.com/user-guide/products/create/bundle/index.html.md). - -## What is an Inventory Kit? - -An inventory kit is a collection of inventory items that are linked to a single product variant. These inventory items can be used to represent different parts of a product, or to represent a bundle of products. - -The Medusa application links inventory items from the [Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/index.html.md) to product variants in the [Product Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/index.html.md). Each variant can have multiple inventory items, and these inventory items can be re-used or shared across variants. - -Using inventory kits, you can implement use cases like: - -- [Multi-part products](#multi-part-products): A product that consists of multiple parts, each with its own inventory item. -- [Bundled products](#bundled-products): A product that is sold as a bundle, where each variant in the bundle product can re-use the inventory items of another product that should be sold as part of the bundle. - -*** - -## Multi-Part Products - -Consider your store sells bicycles that consist of a frame, wheels, and seats, and you want to manage the inventory of these parts separately. - -To implement this in Medusa, you can: - -- Create inventory items for each of the different parts. -- For each bicycle product, add a variant whose inventory kit consists of the inventory items of each of the parts. - -Then, whenever a customer purchases a bicycle, the inventory of each part is updated accordingly.

When the total of the cart or order using this shipping option is greater than `$100`, the shipping option's price becomes free. + +### Using Pricing Module's Service + +For most use cases, it's recommended to use [workflows](#using-workflows) instead of directly using the module's service. + +When adding a price using the [addPrices](https://docs.medusajs.com/resources/references/pricing/addPrices/index.html.md) method of the Pricing Module's service, pass the `rules` property to a price object. + +For example: + +```ts +const priceSet = await pricingModule.addPrices({ + priceSetId: "pset_1", + prices: [ + // default price + { + currency_code: "usd", + amount: 10, + rules: {}, + }, + // price if cart total >= $100 + { + currency_code: "usd", + amount: 0, + rules: { + item_total: { + operator: "gte", + value: 100, + }, + }, + }, + ], +}) +``` + +In this example, you set the default price of a resource (for example, a shipping option), to `$10`. You also add a conditioned price that sets the price to `0` when the cart or order's total is greater than or equal to `$100`. + +### How is the Price Rule Applied? + +The [price calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) mechanism considers a price applicable when the resource that this price is in matches the specified rules. + +For example, a [cart object](https://docs.medusajs.com/api/store#carts_cart_schema) has an `item_total` property. So, if a shipping option has the following price: + +```json +{ + "currency_code": "usd", + "amount": 0, + "rules": { + "item_total": { + "operator": "gte", + "value": 100, + } + } +} +``` + +The shipping option's price is applied when the cart's `item_total` is greater than or equal to `$100`. + +You can also apply the rule on nested relations and properties. For example, to apply a shipping option's price based on the customer's group, you can apply a rule on the `customer.group.id` attribute: + +```json +{ + "currency_code": "usd", + "amount": 0, + "rules": { + "customer.group.id": { + "operator": "eq", + "value": "cusgrp_123" + } + } +} +``` + +In this example, the price is only applied if a cart's customer belongs to the customer group of ID `cusgrp_123`. + +These same rules apply to product variant prices as well, or any other resource that has a price. + + +# Links between Pricing Module and Other Modules + +This document showcases the module links defined between the Pricing Module and other Commerce Modules. + +## Summary + +The Pricing Module has the following links to other modules: + +|First Data Model|Second Data Model|Type|Description| +|---|---|---|---| +| in ||Stored - one-to-one|| +| in ||Stored - one-to-one|| + +*** + +## Fulfillment Module + +The Fulfillment Module provides fulfillment-related functionalities, including shipping options that the customer chooses from when they place their order.

Each rule of a price is represented by the [PriceRule data model](https://docs.medusajs.com/references/pricing/models/PriceRule/index.html.md). - -The `Price` data model has a `rules_count` property, which indicates how many rules, represented by `PriceRule`, are applied to the price. - -For exmaple, you create a price restricted to `10557` zip codes. - -![A diagram showcasing the relation between the PriceRule and Price](https://res.cloudinary.com/dza7lstvk/image/upload/v1709648772/Medusa%20Resources/price-rule-1_vy8bn9.jpg) - -A price can have multiple price rules. - -For example, a price can be restricted by a region and a zip code. - -![A diagram showcasing the relation between the PriceRule and Price with multiple rules.](https://res.cloudinary.com/dza7lstvk/image/upload/v1709649296/Medusa%20Resources/price-rule-3_pwpocz.jpg) - -*** - -## Price List Rules - -Rules applied to a price list are represented by the [PriceListRule data model](https://docs.medusajs.com/references/pricing/models/PriceListRule/index.html.md). - -The `rules_count` property of a `PriceList` indicates how many rules are applied to it. - -![A diagram showcasing the relation between the PriceSet, PriceList, Price, RuleType, and PriceListRuleValue](https://res.cloudinary.com/dza7lstvk/image/upload/v1709641999/Medusa%20Resources/price-list_zd10yd.jpg) - -*** - -## How to Set Rules on a Price? - -### Using Workflows - -Medusa uses the Pricing Module to store prices of different resources, such as product variants and shipping options. - -When you manage one of these resources using [Medusa's workflows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/medusa-workflows-reference/index.html.md) or using the API routes that use them, you can set rules on a price using the `rules` property of the price object. - -For example, when creating a shipping option using the [createShippingOptionsWorkflow](https://docs.medusajs.com/resources/references/medusa-workflows/createShippingOptionsWorkflow/index.html.md) to create a shipping option, you can make the shipping price free based on the cart total: - -```ts highlights={workflowHighlights} -const { result } = await createShippingOptionsWorkflow(container) - .run({ - input: [{ - name: "Standard Shipping", - service_zone_id: "serzo_123", - shipping_profile_id: "sp_123", - provider_id: "prov_123", - type: { - label: "Standard", - description: "Standard shipping", - code: "standard", - }, - price_type: "flat", - prices: [ - // default price - { - currency_code: "usd", - amount: 10, - rules: {}, - }, - // price if cart total >= $100 - { - currency_code: "usd", - amount: 0, - rules: { - item_total: { - operator: "gte", - value: 100, - }, - }, - }, - ], - }], - }) -``` - -In this example, you create a shipping option whose default price is `$10`. When the total of the cart or order using this shipping option is greater than `$100`, the shipping option's price becomes free. - -### Using Pricing Module's Service - -For most use cases, it's recommended to use [workflows](#using-workflows) instead of directly using the module's service. - -When adding a price using the [addPrices](https://docs.medusajs.com/resources/references/pricing/addPrices/index.html.md) method of the Pricing Module's service, pass the `rules` property to a price object. - -For example: - -```ts -const priceSet = await pricingModule.addPrices({ - priceSetId: "pset_1", - prices: [ - // default price - { - currency_code: "usd", - amount: 10, - rules: {}, - }, - // price if cart total >= $100 - { - currency_code: "usd", - amount: 0, - rules: { - item_total: { - operator: "gte", - value: 100, - }, - }, - }, - ], -}) -``` - -In this example, you set the default price of a resource (for example, a shipping option), to `$10`. You also add a conditioned price that sets the price to `0` when the cart or order's total is greater than or equal to `$100`. - -### How is the Price Rule Applied? - -The [price calculation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation/index.html.md) mechanism considers a price applicable when the resource that this price is in matches the specified rules. - -For example, a [cart object](https://docs.medusajs.com/api/store#carts_cart_schema) has an `item_total` property. So, if a shipping option has the following price: - -```json -{ - "currency_code": "usd", - "amount": 0, - "rules": { - "item_total": { - "operator": "gte", - "value": 100, - } - } -} -``` - -The shipping option's price is applied when the cart's `item_total` is greater than or equal to `$100`. - -You can also apply the rule on nested relations and properties. For example, to apply a shipping option's price based on the customer's group, you can apply a rule on the `customer.group.id` attribute: - -```json -{ - "currency_code": "usd", - "amount": 0, - "rules": { - "customer.group.id": { - "operator": "eq", - "value": "cusgrp_123" - } - } -} -``` - -In this example, the price is only applied if a cart's customer belongs to the customer group of ID `cusgrp_123`. - -These same rules apply to product variant prices as well, or any other resource that has a price. - - -# Tax-Inclusive Pricing - -In this document, you’ll learn about tax-inclusive pricing and how it's used when calculating prices. - -## What is Tax-Inclusive Pricing? - -A tax-inclusive price is a price of a resource that includes taxes. Medusa calculates the tax amount from the price rather than adds the amount to it. - -For example, if a product’s price is $50, the tax rate is 2%, and tax-inclusive pricing is enabled, then the product's price is $49, and the applied tax amount is $1. - -*** - -## How is Tax-Inclusive Pricing Set? - -The [PricePreference data model](https://docs.medusajs.com/references/pricing/models/PricePreference/index.html.md) holds the tax-inclusive setting for a context. It has two properties that indicate the context: - -- `attribute`: The name of the attribute to compare against. For example, `region_id` or `currency_code`. -- `value`: The attribute’s value. For example, `reg_123` or `usd`. - -Only `region_id` and `currency_code` are supported as an `attribute` at the moment. - -The `is_tax_inclusive` property indicates whether tax-inclusivity is enabled in the specified context. - -For example: - -```json -{ - "attribute": "currency_code", - "value": "USD", - "is_tax_inclusive": true, -} -``` - -In this example, tax-inclusivity is enabled for the `USD` currency code. - -*** - -## Tax-Inclusive Pricing in Price Calculation - -### Tax Context - -As mentioned in the [Price Calculation documentation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#calculation-context/index.html.md), The `calculatePrices` method accepts as a parameter a calculation context. - -To get accurate tax results, pass the `region_id` and / or `currency_code` in the calculation context. - -### Returned Tax Properties - -The `calculatePrices` method returns two properties related to tax-inclusivity: - -Learn more about the returned properties in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/pricing/price-calculation#returned-price-object/index.html.md). - -- `is_calculated_price_tax_inclusive`: Whether the selected `calculated_price` is tax-inclusive. -- `is_original_price_tax_inclusive` : Whether the selected `original_price` is tax-inclusive. - -A price is considered tax-inclusive if: - -1. 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 - - # Links between Product Module and Other Modules This document showcases the module links defined between the Product Module and other Commerce Modules. @@ -27666,57 +27666,6 @@ createRemoteLinkStep({ ``` -# Configure Selling Products - -In this guide, you'll learn how to set up and configure your products based on their shipping and inventory requirements, the product type, how you want to sell them, or your commerce ecosystem. - -The concepts in this guide are applicable starting from Medusa v2.5.1. - -## Scenario - -Businesses can have different selling requirements: - -1.

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/resources/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/resources/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`. - - -# Application Method - -In this document, you'll learn what an application method is. - -## What is an Application Method? - -The [ApplicationMethod data model](https://docs.medusajs.com/references/promotion/models/ApplicationMethod/index.html.md) defines how a promotion is applied: - -|Property|Purpose| -|---|---| -|\`type\`|Does the promotion discount a fixed amount or a percentage?| -|\`target\_type\`|Is the promotion applied on a cart item, shipping method, or the entire order?| -|\`allocation\`|Is the discounted amount applied on each item or split between the applicable items?| - -## Target Promotion Rules - -When the promotion is applied to a cart item or a shipping method, you can restrict which items/shipping methods the promotion is applied to. - -The `ApplicationMethod` data model has a collection of `PromotionRule` records to restrict which items or shipping methods the promotion applies to. The `target_rules` property represents this relation. - -![A diagram showcasing the target\_rules relation between the ApplicationMethod and PromotionRule data models](https://res.cloudinary.com/dza7lstvk/image/upload/v1709898273/Medusa%20Resources/application-method-target-rules_hqaymz.jpg) - -In this example, the promotion is only applied on products in the cart having the SKU `SHIRT`. - -*** - -## Buy Promotion Rules - -When the promotion’s type is `buyget`, you must specify the “buy X” condition. For example, a cart must have two shirts before the promotion can be applied. - -The application method has a collection of `PromotionRule` items to define the “buy X” rule.

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) - - -# 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 Stock Location Module and other Commerce Modules. ## Summary -The Promotion Module has the following links to other modules: +The Stock Location 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| |---|---|---|---| +| in ||Stored - many-to-one|| | in ||Stored - many-to-many|| -| in ||Read-only - has one|| +| in ||Read-only - has many|| | in ||Stored - many-to-many|| *** -## Cart Module +## Fulfillment Module -A promotion can be applied on line items and shipping methods of a cart.

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 managing carts and adding line items to them. + +By default, you can add product variants to the cart, where the price of its associated line item is based on the product variant's price. However, you can build customizations to add line items with custom prices to the cart. This is useful when integrating an Enterprise Resource Planning (ERP), Product Information Management (PIM), or other third-party services that provide real-time prices for your products. + +To showcase how to add line items with custom prices to the cart, this guide uses [GoldAPI.io](https://www.goldapi.io) as an example of a third-party system that you can integrate for real-time prices. You can follow the same approach for other third-party integrations that provide custom pricing. + +You can follow this guide whether you're new to Medusa or an advanced Medusa developer. + +### Summary + +This guide will teach you how to: + +- Install and set up Medusa. +- Integrate the third-party service [GoldAPI.io](https://www.goldapi.io) that retrieves real-time prices for metals like Gold and Silver. +- Add an API route to add a product variant that has metals, such as a gold ring, to the cart with the real-time price retrieved from the third-party service. + +![Diagram showcasing overview of implementation for adding an item to cart from storefront.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738920014/Medusa%20Resources/custom-line-item-3_zu3qh2.jpg) + +- [Custom Item Price Repository](https://github.com/medusajs/examples/tree/main/custom-item-price): Find the full code for this guide in this repository. +- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1738246728/OpenApi/Custom_Item_Price_gdfnl3.yaml): Import this OpenApi Specs file into tools like Postman. + +*** + +## Step 1: Install a Medusa Application + +### Prerequisites + +- [Node.js v20+](https://nodejs.org/en/download) +- [Git CLI tool](https://git-scm.com/downloads) +- [PostgreSQL](https://www.postgresql.org/download/) + +Start by installing the Medusa application on your machine with the following command: + +```bash +npx create-medusa-app@latest +``` + +You'll first be asked for the project's name. You can also optionally choose to install the [Next.js starter storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md). + +Afterwards, the installation process will start, which will install the Medusa application in a directory with your project's name. If you chose to install the Next.js starter, it'll be installed in a separate directory with the `{project-name}-storefront` name. + +The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more about Medusa's architecture in [this documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). + +Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user.

You can create a free account.](https://www.goldapi.io) + +To integrate third-party services into 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 Metal Price Module that uses the GoldAPI.io service to retrieve real-time prices for metals like Gold and Silver. You'll use this module later to retrieve the real-time price of a product variant based on the metals in it, and add it to the cart with that custom price. + +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/metal-prices`. + +![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247192/Medusa%20Resources/custom-item-price-1_q16evr.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 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 Metal Prices Module's service that connects to the GoldAPI.io service to retrieve real-time prices for metals. + +Start by creating the file `src/modules/metal-prices/service.ts` with the following content: + +![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247303/Medusa%20Resources/custom-item-price-2_eaefis.jpg) + +```ts title="src/modules/metal-prices/service.ts" +type Options = { + accessToken: string + sandbox?: boolean +} + +export default class MetalPricesModuleService { + protected options_: Options + + constructor({}, options: Options) { + this.options_ = options + } +} +``` + +A module can accept options that are passed to its service. You define an `Options` type that indicates the options the module accepts. It accepts two options: + +- `accessToken`: The access token for the GoldAPI.io service. +- `sandbox`: A boolean that indicates whether to simulate sending requests to the GoldAPI.io service. This is useful when running in a test environment. + +The service's constructor receives the module's options as a second parameter. You store the options in the service's `options_` property. + +A module has a container of Medusa Framework tools and local resources in the module that you can access in the service constructor's first parameter. Learn more in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md). + +#### Add Method to Retrieve Metal Prices + +Next, you'll add the method to retrieve the metal prices from the third-party service. + +First, add the following types at the beginning of `src/modules/metal-prices/service.ts`: + +```ts title="src/modules/metal-prices/service.ts" +export enum MetalSymbols { + Gold = "XAU", + Silver = "XAG", + Platinum = "XPT", + Palladium = "XPD" +} + +export type PriceResponse = { + metal: MetalSymbols + currency: string + exchange: string + symbol: string + price: number + [key: string]: unknown +} + +``` + +The `MetalSymbols` enum defines the symbols for metals like Gold, Silver, Platinum, and Palladium. The `PriceResponse` type defines the structure of the response from the GoldAPI.io's endpoint. + +Next, add the method `getMetalPrices` to the `MetalPricesModuleService` class: + +```ts title="src/modules/metal-prices/service.ts" +import { MedusaError } from "@medusajs/framework/utils" + +// ... + +export default class MetalPricesModuleService { + // ... + async getMetalPrice( + symbol: MetalSymbols, + currency: string + ): Promise { + const upperCaseSymbol = symbol.toUpperCase() + const upperCaseCurrency = currency.toUpperCase() + + return fetch(`https://www.goldapi.io/api/${upperCaseSymbol}/${upperCaseCurrency}`, { + headers: { + "x-access-token": this.options_.accessToken, + "Content-Type": "application/json", + }, + redirect: "follow", + }).then((response) => response.json()) + .then((response) => { + if (response.error) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + response.error + ) + } + + return response + }) + } +} +``` + +The `getMetalPrice` method accepts the metal symbol and currency as parameters. You send a request to GoldAPI.io's `/api/{symbol}/{currency}` endpoint to retrieve the metal's price, also passing the access token in the request's headers. + +If the response contains an error, you throw a `MedusaError` with the error message. Otherwise, you return the response, which is of type `PriceResponse`. + +#### Add Helper Methods + +You'll also add two helper methods to the `MetalPricesModuleService`. The first one is `getMetalSymbols` that returns the metal symbols as an array of strings: + +```ts title="src/modules/metal-prices/service.ts" +export default class MetalPricesModuleService { + // ... + async getMetalSymbols(): Promise { + return Object.values(MetalSymbols) + } +} +``` + +The second is `getMetalSymbol` that receives a name like `gold` and returns the corresponding metal symbol: + +```ts title="src/modules/metal-prices/service.ts" +export default class MetalPricesModuleService { + // ... + async getMetalSymbol(name: string): Promise { + const formattedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() + return MetalSymbols[formattedName as keyof typeof MetalSymbols] + } +} +``` + +You'll use these methods in later steps. + +### 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/metal-prices/index.ts` with the following content: + +![The directory structure of the Metal Prices Module after adding the definition file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248049/Medusa%20Resources/custom-item-price-3_imtbuw.jpg) + +```ts title="src/modules/metal-prices/index.ts" +import { Module } from "@medusajs/framework/utils" +import MetalPricesModuleService from "./service" + +export const METAL_PRICES_MODULE = "metal-prices" + +export default Module(METAL_PRICES_MODULE, { + service: MetalPricesModuleService, +}) +``` + +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 `metal-prices`. +2. An object with a required property `service` indicating the module's service. + +### Add Module to Medusa's Configurations + +Once you finish building the module, add it to Medusa's configurations to start using it. + +In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/metal-prices", + options: { + accessToken: process.env.GOLD_API_TOKEN, + sandbox: process.env.GOLD_API_SANDBOX === "true", + }, + }, + ], +}) +``` + +Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. + +The object also has an `options` property that accepts the module's options. You set the `accessToken` and `sandbox` options based on environment variables. + +You'll find the access token at the top of your GoldAPI.io dashboard. + +![The access token is below the "API Token" header of your GoldAPI.io dashboard.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248335/Medusa%20Resources/Screenshot_2025-01-30_at_4.44.07_PM_xht3j4.png) + +Set the access token as an environment variable in `.env`: + +```bash +GOLD_API_TOKEN= +``` + +You'll start using the module in the next steps. + +*** + +## Step 3: Add Custom Item to Cart Workflow + +In this section, you'll implement the logic to retrieve the real-time price of a variant based on the metals in it, then add the variant to the cart with the custom price. You'll implement this logic in 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 endpoint. + +Learn more about workflows in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) + +The workflow you'll implement in this section has the following steps: + +- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's ID and currency using Query. +- [useQueryGraphStep (Retrieve Variant)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the variant's details using Query +- [getVariantMetalPricesStep](#getvariantmetalpricesstep): Retrieve the variant's price using the third-party service. +- [addToCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/addToCartWorkflow/index.html.md): Add the item with the custom price to the cart. +- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the updated cart's details using Query. + +`useQueryGraphStep` and `addToCartWorkflow` are available through Medusa's core workflows package. You'll only implement the `getVariantMetalPricesStep`. + +### getVariantMetalPricesStep + +The `getVariantMetalPricesStep` will retrieve the real-time metal price of a variant received as an input. + +To create the step, create the file `src/workflows/steps/get-variant-metal-prices.ts` with the following content: + +![The directory structure after adding the step file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738249036/Medusa%20Resources/custom-item-price-4_kumzdc.jpg) + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +import { createStep } from "@medusajs/framework/workflows-sdk" +import { ProductVariantDTO } from "@medusajs/framework/types" +import { METAL_PRICES_MODULE } from "../../modules/metal-prices" +import MetalPricesModuleService from "../../modules/metal-prices/service" + +export type GetVariantMetalPricesStepInput = { + variant: ProductVariantDTO & { + calculated_price?: { + calculated_amount: number + } + } + currencyCode: string + quantity?: number +} + +export const getVariantMetalPricesStep = createStep( + "get-variant-metal-prices", + async ({ + variant, + currencyCode, + quantity = 1, + }: GetVariantMetalPricesStepInput, { container }) => { + const metalPricesModuleService: MetalPricesModuleService = + container.resolve(METAL_PRICES_MODULE) + + // TODO + } +) +``` + +You create a step with `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's unique name, which is `get-variant-metal-prices`. +2. An async function that receives two parameters: + - An input object with the variant, currency code, and quantity. The variant has a `calculated_price` property that holds the variant's fixed price in the Medusa application. This is useful when you want to add a fixed price to the real-time custom price, such as handling fees. + - The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. + +In the step function, so far you only resolve the Metal Prices Module's service from the Medusa container. + +Next, you'll validate that the specified variant can have its price calculated. Add the following import at the top of the file: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +import { MedusaError } from "@medusajs/framework/utils" +``` + +And replace the `TODO` in the step function with the following: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +const variantMetal = variant.options.find( + (option) => option.option?.title === "Metal" +)?.value +const metalSymbol = await metalPricesModuleService + .getMetalSymbol(variantMetal || "") + +if (!metalSymbol) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Variant doesn't have metal. Make sure the variant's SKU matches a metal symbol." + ) +} + +if (!variant.weight) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Variant doesn't have weight. Make sure the variant has weight to calculate its price." + ) +} + +// TODO retrieve custom price +``` + +In the code above, you first retrieve the metal option's value from the variant's options, assuming that a variant has metals if it has a `Metal` option. Then, you retrieve the metal symbol of the option's value using the `getMetalSymbol` method of the Metal Prices Module's service. + +If the variant doesn't have a metal in its options, the option's value is not valid, or the variant doesn't have a weight, you throw an error. The weight is necessary to calculate the price based on the metal's price per weight. + +Next, you'll retrieve the real-time price of the metal using the third-party service. Replace the `TODO` with the following: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +let price = variant.calculated_price?.calculated_amount || 0 +const weight = variant.weight +const { price: metalPrice } = await metalPricesModuleService.getMetalPrice( + metalSymbol as MetalSymbols, currencyCode +) +price += (metalPrice * weight * quantity) + +return new StepResponse(price) +``` + +In the code above, you first set the price to the variant's fixed price, if it has one. Then, you retrieve the metal's price using the `getMetalPrice` method of the Metal Prices Module's service. + +Finally, you calculate the price by multiplying the metal's price by the variant's weight and the quantity to add to the cart, then add the fixed price to it. + +Every step must return a `StepResponse` instance. The `StepResponse` constructor accepts the step's output as a parameter, which in this case is the variant's price. + +### Create addCustomToCartWorkflow + +Now that you have the `getVariantMetalPricesStep`, you can create the workflow that adds the item with custom pricing to the cart. + +Create the file `src/workflows/add-custom-to-cart.ts` with the following content: + +![The directory structure after adding the workflow file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738251380/Medusa%20Resources/custom-item-price-5_zorahv.jpg) + +```ts title="src/workflows/add-custom-to-cart.ts" highlights={workflowHighlights} +import { createWorkflow } from "@medusajs/framework/workflows-sdk" +import { useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { QueryContext } from "@medusajs/framework/utils" + +type AddCustomToCartWorkflowInput = { + cart_id: string + item: { + variant_id: string + quantity: number + metadata?: Record + } +} + +export const addCustomToCartWorkflow = createWorkflow( + "add-custom-to-cart", + ({ cart_id, item }: AddCustomToCartWorkflowInput) => { + // @ts-ignore + const { data: carts } = useQueryGraphStep({ + entity: "cart", + filters: { id: cart_id }, + fields: ["id", "currency_code"], + }) + + const { data: variants } = useQueryGraphStep({ + entity: "variant", + fields: [ + "*", + "options.*", + "options.option.*", + "calculated_price.*", + ], + filters: { + id: item.variant_id, + }, + options: { + throwIfKeyNotFound: true, + }, + context: { + calculated_price: QueryContext({ + currency_code: carts[0].currency_code, + }), + }, + }).config({ name: "retrieve-variant" }) + + // TODO add more steps + } +) +``` + +You create a workflow with `createWorkflow` from the Workflows SDK. It accepts two parameters: + +1. The workflow's unique name, which is `add-custom-to-cart`. +2. A function that receives an input object with the cart's ID and the item to add to the cart. The item has the variant's ID, quantity, and optional metadata. + +In the function, you first retrieve the cart's details using the `useQueryGraphStep` helper step. This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) which is a Modules SDK tool that retrieves data across modules. You use it to retrieve the cart's ID and currency code. + +You also retrieve the variant's details using the `useQueryGraphStep` helper step. You pass the variant's ID to the step's filters and specify the fields to retrieve. To retrieve the variant's price based on the cart's context, you pass the cart's currency code to the `calculated_price` context. + +Next, you'll retrieve the variant's real-time price using the `getVariantMetalPricesStep` you created earlier. First, add the following import: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { + getVariantMetalPricesStep, + GetVariantMetalPricesStepInput, +} from "./steps/get-variant-metal-prices" +``` + +Then, replace the `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +const price = getVariantMetalPricesStep({ + variant: variants[0], + currencyCode: carts[0].currency_code, + quantity: item.quantity, +} as unknown as GetVariantMetalPricesStepInput) + +// TODO add item with custom price to cart +``` + +You execute the `getVariantMetalPricesStep` passing it the variant's details, the cart's currency code, and the quantity of the item to add to the cart. The step returns the variant's custom price. + +Next, you'll add the item with the custom price to the cart. First, add the following imports at the top of the file: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { transform } from "@medusajs/framework/workflows-sdk" +import { addToCartWorkflow } from "@medusajs/medusa/core-flows" +``` + +Then, replace the `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +const itemToAdd = transform({ + item, + price, +}, (data) => { + return [{ + ...data.item, + unit_price: data.price, + }] +}) + +addToCartWorkflow.runAsStep({ + input: { + items: itemToAdd, + cart_id, + }, +}) + +// TODO retrieve and return cart +``` + +You prepare the item to add to the cart using `transform` from the Workflows SDK. It allows you to manipulate and create variables in a workflow. After that, you use Medusa's `addToCartWorkflow` to add the item with the custom price to the cart. + +A workflow's constructor function has some constraints in implementation, which is why you need to use `transform` for variable manipulation. Learn more about these constraints in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). + +Lastly, you'll retrieve the cart's details again and return them. Add the following import at the beginning of the file: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { WorkflowResponse } from "@medusajs/framework/workflows-sdk" +``` + +And replace the last `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +// @ts-ignore +const { data: updatedCarts } = useQueryGraphStep({ + entity: "cart", + filters: { id: cart_id }, + fields: ["id", "items.*"], +}).config({ name: "refetch-cart" }) + +return new WorkflowResponse({ + cart: updatedCarts[0], +}) +``` + +In the code above, you retrieve the updated cart's details using the `useQueryGraphStep` helper step. To return data from the workflow, you create and return a `WorkflowResponse` instance. It accepts as a parameter the data to return, which is the updated cart. + +In the next step, you'll use the workflow in a custom route to add an item with a custom price to the cart. + +*** + +## Step 4: Create Add Custom Item to Cart API Route + +Now that you've implemented the logic to add an item with a custom price to the cart, you'll expose this functionality in an API route. + +An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. You'll create an API route at the path `/store/carts/:id/line-items-metals` that executes the workflow from the previous step to add a product variant with custom price to the cart. + +Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). + +### 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`. So, to create the `/store/carts/:id/line-items-metals` API route, create the file `src/api/store/carts/[id]/line-items-metals/route.ts` with the following content: + +![The directory structure after adding the API route file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738252712/Medusa%20Resources/custom-item-price-6_deecbu.jpg) + +```ts title="src/api/store/carts/[id]/line-items-metals/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework" +import { HttpTypes } from "@medusajs/framework/types" +import { addCustomToCartWorkflow } from "../../../../../workflows/add-custom-to-cart" + +export const POST = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + const { id } = req.params + const item = req.validatedBody + + const { result } = await addCustomToCartWorkflow(req.scope) + .run({ + input: { + cart_id: id, + item, + }, + }) + + res.status(200).json({ cart: result.cart }) +} +``` + +Since you export a `POST` function in this file, you're exposing a `POST` API route at `/store/carts/:id/line-items-metals`. The route handler function accepts two parameters: + +1. A request object with details and context on the request, such as path and body parameters. +2. A response object to manipulate and send the response. + +In the function, you retrieve the cart's ID from the path parameter, and the item's details from the request body. This API route will accept the same request body parameters as Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). + +Then, you execute the `addCustomToCartWorkflow` by invoking it, passing it the Medusa container, which is available in the request's `scope` property, then executing its `run` method. You pass the workflow's input object with the cart's ID and the item to add to the cart. + +Finally, you return a response with the updated cart's details. + +### Add Request Body Validation Middleware + +To ensure that the request body contains the required parameters, you'll add a middleware that validates the incoming request's body based on a defined schema. + +A middleware is a function executed before the API route when a request is sent to it. You define middlewares in Medusa in the `src/api/middlewares.ts` directory. + +Learn more about middlewares in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). + +To add a validation middleware to the custom API route, create the file `src/api/middlewares.ts` with the following content: + +![The directory structure after adding the middleware file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253099/Medusa%20Resources/custom-item-price-7_l7iw2a.jpg) + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformBody, +} from "@medusajs/framework/http" +import { + StoreAddCartLineItem, +} from "@medusajs/medusa/api/store/carts/validators" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/carts/:id/line-items-metals", + method: "POST", + middlewares: [ + validateAndTransformBody( + StoreAddCartLineItem + ), + ], + }, + ], +}) +``` + +In this file, you export the middlewares definition using `defineMiddlewares` from the Medusa Framework. This function accepts an object having a `routes` property, which is an array of middleware configurations to apply on routes. + +You pass in the `routes` array an object having the following properties: + +- `matcher`: The route to apply the middleware on. +- `method`: The HTTP method to apply the middleware on for the specified API route. +- `middlewares`: An array of the middlewares to apply. You apply the `validateAndTransformBody` middleware, which validates the request body based on the `StoreAddCartLineItem` schema. This validation schema is the same schema used for Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). + +Any request sent to the `/store/carts/:id/line-items-metals` API route will now fail if it doesn't have the required parameters. + +Learn more about API route validation in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/validation/index.html.md). + +### Prepare to Test API Route + +Before you test the API route, you'll prepare and retrieve the necessary data to add a product variant with a custom price to the cart. + +#### Create Product with Metal Variant + +You'll first create a product that has a `Metal` option, and variant(s) with values for this option. + +Start the Medusa application with the following command: + +```bash npm2yarn +npm run dev +``` + +Then, open the Medusa Admin dashboard at `localhost:9000/app` and log in with the email and password you created when you installed the Medusa application in the first step. + +Once you log in, click on Products in the sidebar, then click the Create button at the top right. + +![Click on Products in the sidebar at the left, then click on the Create button at the top right of the content](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253415/Medusa%20Resources/Screenshot_2025-01-30_at_6.09.36_PM_ee0jr2.png) + +Then, in the Create Product form: + +1. Enter a name for the product, and optionally enter other details like description. +2. Enable the "Yes, this is a product with variants" toggle. +3. Under Product Options, enter "Metal" for the title, and enter "Gold" for the values. + +Once you're done, click the Continue button. + +![Fill in the product details, enable the "Yes, this is a product with variants" toggle, and add the "Metal" option with "Gold" value](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253520/Medusa%20Resources/Screenshot_2025-01-30_at_6.11.29_PM_lqxth9.png) + +You can skip the next two steps by clicking the Continue button again, then the Publish button. + +Once you're done, the product's page will open.

To do that: + +1. Click on the three-dots icon at the top right of the Variants section. +2. Choose "Edit Prices" from the dropdown. + +![Click on the three-dots icon at the top right of the Variants section, then choose "Edit Prices"](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255203/Medusa%20Resources/Screenshot_2025-01-30_at_6.39.35_PM_s3jpxh.png) + +For each cell in the table, either enter a fixed price for the specified currency or leave it as `0`.

This ensures the request's operations are scoped to the publishable API key's associated sales channels. For example, products that aren't available in a cart's sales channel can't be added to it. + +To retrieve the publishable API key, on the Medusa Admin: + +1. Click on Settings in the sidebar at the bottom left. +2. Click on Publishable API Keys from the sidebar, then click on a publishable API key in the list. + +![Click on publishable API keys in the Settings sidebar, then click on a publishable API key in the list](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254523/Medusa%20Resources/Screenshot_2025-01-30_at_6.28.17_PM_mldscc.png) + +3.

A cart must be associated with a region. So, to retrieve the ID of a region in your store, send a `GET` request to the `/store/regions` API route: + +```bash +curl 'localhost:9000/store/regions' \ +-H 'x-publishable-api-key: {api_key}' +``` + +Make sure to replace `{api_key}` with the publishable API key you copied earlier. + +This will return a list of regions. Copy the ID of one of the regions. + +Then, send a `POST` request to the `/store/carts` API route to create a cart: + +```bash +curl -X POST 'localhost:9000/store/carts' \ +-H 'x-publishable-api-key: {api_key}' \ +-H 'Content-Type: application/json' \ +--data '{ + "region_id": "{region_id}" +}' +``` + +Make sure to replace `{api_key}` with the publishable API key you copied earlier, and `{region_id}` with the ID of a region from the previous request. + +This will return the created cart. Copy the ID of the cart to use it next. + +Finally, to add the Gold variant to the cart with a custom price, send a `POST` request to the `/store/carts/:id/line-items-metals` API route: + +```bash +curl -X POST 'localhost:9000/store/carts/{cart_id}/line-items-metals' \ +-H 'x-publishable-api-key: {api_key}' \ +-H 'Content-Type: application/json' \ +--data '{ + "variant_id": "{variant_id}", + "quantity": 1 +}' +``` + +Make sure to replace: + +- `{api_key}` with the publishable API key you copied earlier. +- `{cart_id}` with the ID of the cart you created. +- `{variant_id}` with the ID of the Gold variant you created. + +This will return the cart's details, where you can see in its `items` array the item with the custom price: + +```json title="Example Response" +{ + "cart": { + "items": [ + { + "variant_id": "{variant_id}", + "quantity": 1, + "is_custom_price": true, + // example custom price + "unit_price": 2000 + } + ] + } +} +``` + +The price will be the result of the calculation you've implemented earlier, which is the fixed price of the variant plus the real-time price of the metal, multiplied by the weight of the variant and the quantity added to the cart. + +This price will be reflected in the cart's total price, and you can proceed to checkout with the custom-priced item. + +*** + +## Next Steps + +You've now implemented custom item pricing in Medusa.

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 managing carts and adding line items to them. - -By default, you can add product variants to the cart, where the price of its associated line item is based on the product variant's price. However, you can build customizations to add line items with custom prices to the cart. This is useful when integrating an Enterprise Resource Planning (ERP), Product Information Management (PIM), or other third-party services that provide real-time prices for your products. - -To showcase how to add line items with custom prices to the cart, this guide uses [GoldAPI.io](https://www.goldapi.io) as an example of a third-party system that you can integrate for real-time prices. You can follow the same approach for other third-party integrations that provide custom pricing. - -You can follow this guide whether you're new to Medusa or an advanced Medusa developer. - -### Summary - -This guide will teach you how to: - -- Install and set up Medusa. -- Integrate the third-party service [GoldAPI.io](https://www.goldapi.io) that retrieves real-time prices for metals like Gold and Silver. -- Add an API route to add a product variant that has metals, such as a gold ring, to the cart with the real-time price retrieved from the third-party service. - -![Diagram showcasing overview of implementation for adding an item to cart from storefront.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738920014/Medusa%20Resources/custom-line-item-3_zu3qh2.jpg) - -- [Custom Item Price Repository](https://github.com/medusajs/examples/tree/main/custom-item-price): Find the full code for this guide in this repository. -- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1738246728/OpenApi/Custom_Item_Price_gdfnl3.yaml): Import this OpenApi Specs file into tools like Postman. - -*** - -## Step 1: Install a Medusa Application - -### Prerequisites - -- [Node.js v20+](https://nodejs.org/en/download) -- [Git CLI tool](https://git-scm.com/downloads) -- [PostgreSQL](https://www.postgresql.org/download/) - -Start by installing the Medusa application on your machine with the following command: - -```bash -npx create-medusa-app@latest -``` - -You'll first be asked for the project's name. You can also optionally choose to install the [Next.js starter storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md). - -Afterwards, the installation process will start, which will install the Medusa application in a directory with your project's name. If you chose to install the Next.js starter, it'll be installed in a separate directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more about Medusa's architecture in [this documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user. Enter the user's credentials and submit the form.

You can create a free account.](https://www.goldapi.io) - -To integrate third-party services into 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 Metal Price Module that uses the GoldAPI.io service to retrieve real-time prices for metals like Gold and Silver. You'll use this module later to retrieve the real-time price of a product variant based on the metals in it, and add it to the cart with that custom price. - -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/metal-prices`. - -![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247192/Medusa%20Resources/custom-item-price-1_q16evr.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 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 Metal Prices Module's service that connects to the GoldAPI.io service to retrieve real-time prices for metals. - -Start by creating the file `src/modules/metal-prices/service.ts` with the following content: - -![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247303/Medusa%20Resources/custom-item-price-2_eaefis.jpg) - -```ts title="src/modules/metal-prices/service.ts" -type Options = { - accessToken: string - sandbox?: boolean -} - -export default class MetalPricesModuleService { - protected options_: Options - - constructor({}, options: Options) { - this.options_ = options - } -} -``` - -A module can accept options that are passed to its service. You define an `Options` type that indicates the options the module accepts. It accepts two options: - -- `accessToken`: The access token for the GoldAPI.io service. -- `sandbox`: A boolean that indicates whether to simulate sending requests to the GoldAPI.io service. This is useful when running in a test environment. - -The service's constructor receives the module's options as a second parameter. You store the options in the service's `options_` property. - -A module has a container of Medusa Framework tools and local resources in the module that you can access in the service constructor's first parameter. Learn more in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md). - -#### Add Method to Retrieve Metal Prices - -Next, you'll add the method to retrieve the metal prices from the third-party service. - -First, add the following types at the beginning of `src/modules/metal-prices/service.ts`: - -```ts title="src/modules/metal-prices/service.ts" -export enum MetalSymbols { - Gold = "XAU", - Silver = "XAG", - Platinum = "XPT", - Palladium = "XPD" -} - -export type PriceResponse = { - metal: MetalSymbols - currency: string - exchange: string - symbol: string - price: number - [key: string]: unknown -} - -``` - -The `MetalSymbols` enum defines the symbols for metals like Gold, Silver, Platinum, and Palladium. The `PriceResponse` type defines the structure of the response from the GoldAPI.io's endpoint. - -Next, add the method `getMetalPrices` to the `MetalPricesModuleService` class: - -```ts title="src/modules/metal-prices/service.ts" -import { MedusaError } from "@medusajs/framework/utils" - -// ... - -export default class MetalPricesModuleService { - // ... - async getMetalPrice( - symbol: MetalSymbols, - currency: string - ): Promise { - const upperCaseSymbol = symbol.toUpperCase() - const upperCaseCurrency = currency.toUpperCase() - - return fetch(`https://www.goldapi.io/api/${upperCaseSymbol}/${upperCaseCurrency}`, { - headers: { - "x-access-token": this.options_.accessToken, - "Content-Type": "application/json", - }, - redirect: "follow", - }).then((response) => response.json()) - .then((response) => { - if (response.error) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - response.error - ) - } - - return response - }) - } -} -``` - -The `getMetalPrice` method accepts the metal symbol and currency as parameters. You send a request to GoldAPI.io's `/api/{symbol}/{currency}` endpoint to retrieve the metal's price, also passing the access token in the request's headers. - -If the response contains an error, you throw a `MedusaError` with the error message. Otherwise, you return the response, which is of type `PriceResponse`. - -#### Add Helper Methods - -You'll also add two helper methods to the `MetalPricesModuleService`. The first one is `getMetalSymbols` that returns the metal symbols as an array of strings: - -```ts title="src/modules/metal-prices/service.ts" -export default class MetalPricesModuleService { - // ... - async getMetalSymbols(): Promise { - return Object.values(MetalSymbols) - } -} -``` - -The second is `getMetalSymbol` that receives a name like `gold` and returns the corresponding metal symbol: - -```ts title="src/modules/metal-prices/service.ts" -export default class MetalPricesModuleService { - // ... - async getMetalSymbol(name: string): Promise { - const formattedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() - return MetalSymbols[formattedName as keyof typeof MetalSymbols] - } -} -``` - -You'll use these methods in later steps. - -### 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/metal-prices/index.ts` with the following content: - -![The directory structure of the Metal Prices Module after adding the definition file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248049/Medusa%20Resources/custom-item-price-3_imtbuw.jpg) - -```ts title="src/modules/metal-prices/index.ts" -import { Module } from "@medusajs/framework/utils" -import MetalPricesModuleService from "./service" - -export const METAL_PRICES_MODULE = "metal-prices" - -export default Module(METAL_PRICES_MODULE, { - service: MetalPricesModuleService, -}) -``` - -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 `metal-prices`. -2. An object with a required property `service` indicating the module's service. - -### Add Module to Medusa's Configurations - -Once you finish building the module, add it to Medusa's configurations to start using it. - -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/metal-prices", - options: { - accessToken: process.env.GOLD_API_TOKEN, - sandbox: process.env.GOLD_API_SANDBOX === "true", - }, - }, - ], -}) -``` - -Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. - -The object also has an `options` property that accepts the module's options. You set the `accessToken` and `sandbox` options based on environment variables. - -You'll find the access token at the top of your GoldAPI.io dashboard. - -![The access token is below the "API Token" header of your GoldAPI.io dashboard.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248335/Medusa%20Resources/Screenshot_2025-01-30_at_4.44.07_PM_xht3j4.png) - -Set the access token as an environment variable in `.env`: - -```bash -GOLD_API_TOKEN= -``` - -You'll start using the module in the next steps. - -*** - -## Step 3: Add Custom Item to Cart Workflow - -In this section, you'll implement the logic to retrieve the real-time price of a variant based on the metals in it, then add the variant to the cart with the custom price. You'll implement this logic in 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 endpoint. - -Learn more about workflows in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) - -The workflow you'll implement in this section has the following steps: - -- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's ID and currency using Query. -- [useQueryGraphStep (Retrieve Variant)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the variant's details using Query -- [getVariantMetalPricesStep](#getvariantmetalpricesstep): Retrieve the variant's price using the third-party service. -- [addToCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/addToCartWorkflow/index.html.md): Add the item with the custom price to the cart. -- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the updated cart's details using Query. - -`useQueryGraphStep` and `addToCartWorkflow` are available through Medusa's core workflows package. You'll only implement the `getVariantMetalPricesStep`. - -### getVariantMetalPricesStep - -The `getVariantMetalPricesStep` will retrieve the real-time metal price of a variant received as an input. - -To create the step, create the file `src/workflows/steps/get-variant-metal-prices.ts` with the following content: - -![The directory structure after adding the step file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738249036/Medusa%20Resources/custom-item-price-4_kumzdc.jpg) - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -import { createStep } from "@medusajs/framework/workflows-sdk" -import { ProductVariantDTO } from "@medusajs/framework/types" -import { METAL_PRICES_MODULE } from "../../modules/metal-prices" -import MetalPricesModuleService from "../../modules/metal-prices/service" - -export type GetVariantMetalPricesStepInput = { - variant: ProductVariantDTO & { - calculated_price?: { - calculated_amount: number - } - } - currencyCode: string - quantity?: number -} - -export const getVariantMetalPricesStep = createStep( - "get-variant-metal-prices", - async ({ - variant, - currencyCode, - quantity = 1, - }: GetVariantMetalPricesStepInput, { container }) => { - const metalPricesModuleService: MetalPricesModuleService = - container.resolve(METAL_PRICES_MODULE) - - // TODO - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `get-variant-metal-prices`. -2. An async function that receives two parameters: - - An input object with the variant, currency code, and quantity. The variant has a `calculated_price` property that holds the variant's fixed price in the Medusa application. This is useful when you want to add a fixed price to the real-time custom price, such as handling fees. - - The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, so far you only resolve the Metal Prices Module's service from the Medusa container. - -Next, you'll validate that the specified variant can have its price calculated. Add the following import at the top of the file: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -import { MedusaError } from "@medusajs/framework/utils" -``` - -And replace the `TODO` in the step function with the following: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -const variantMetal = variant.options.find( - (option) => option.option?.title === "Metal" -)?.value -const metalSymbol = await metalPricesModuleService - .getMetalSymbol(variantMetal || "") - -if (!metalSymbol) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Variant doesn't have metal. Make sure the variant's SKU matches a metal symbol." - ) -} - -if (!variant.weight) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Variant doesn't have weight. Make sure the variant has weight to calculate its price." - ) -} - -// TODO retrieve custom price -``` - -In the code above, you first retrieve the metal option's value from the variant's options, assuming that a variant has metals if it has a `Metal` option. Then, you retrieve the metal symbol of the option's value using the `getMetalSymbol` method of the Metal Prices Module's service. - -If the variant doesn't have a metal in its options, the option's value is not valid, or the variant doesn't have a weight, you throw an error. The weight is necessary to calculate the price based on the metal's price per weight. - -Next, you'll retrieve the real-time price of the metal using the third-party service. Replace the `TODO` with the following: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -let price = variant.calculated_price?.calculated_amount || 0 -const weight = variant.weight -const { price: metalPrice } = await metalPricesModuleService.getMetalPrice( - metalSymbol as MetalSymbols, currencyCode -) -price += (metalPrice * weight * quantity) - -return new StepResponse(price) -``` - -In the code above, you first set the price to the variant's fixed price, if it has one. Then, you retrieve the metal's price using the `getMetalPrice` method of the Metal Prices Module's service. - -Finally, you calculate the price by multiplying the metal's price by the variant's weight and the quantity to add to the cart, then add the fixed price to it. - -Every step must return a `StepResponse` instance. The `StepResponse` constructor accepts the step's output as a parameter, which in this case is the variant's price. - -### Create addCustomToCartWorkflow - -Now that you have the `getVariantMetalPricesStep`, you can create the workflow that adds the item with custom pricing to the cart. - -Create the file `src/workflows/add-custom-to-cart.ts` with the following content: - -![The directory structure after adding the workflow file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738251380/Medusa%20Resources/custom-item-price-5_zorahv.jpg) - -```ts title="src/workflows/add-custom-to-cart.ts" highlights={workflowHighlights} -import { createWorkflow } from "@medusajs/framework/workflows-sdk" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" -import { QueryContext } from "@medusajs/framework/utils" - -type AddCustomToCartWorkflowInput = { - cart_id: string - item: { - variant_id: string - quantity: number - metadata?: Record - } -} - -export const addCustomToCartWorkflow = createWorkflow( - "add-custom-to-cart", - ({ cart_id, item }: AddCustomToCartWorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - filters: { id: cart_id }, - fields: ["id", "currency_code"], - }) - - const { data: variants } = useQueryGraphStep({ - entity: "variant", - fields: [ - "*", - "options.*", - "options.option.*", - "calculated_price.*", - ], - filters: { - id: item.variant_id, - }, - options: { - throwIfKeyNotFound: true, - }, - context: { - calculated_price: QueryContext({ - currency_code: carts[0].currency_code, - }), - }, - }).config({ name: "retrieve-variant" }) - - // TODO add more steps - } -) -``` - -You create a workflow with `createWorkflow` from the Workflows SDK. It accepts two parameters: - -1. The workflow's unique name, which is `add-custom-to-cart`. -2. A function that receives an input object with the cart's ID and the item to add to the cart. The item has the variant's ID, quantity, and optional metadata. - -In the function, you first retrieve the cart's details using the `useQueryGraphStep` helper step. This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) which is a Modules SDK tool that retrieves data across modules. You use it to retrieve the cart's ID and currency code. - -You also retrieve the variant's details using the `useQueryGraphStep` helper step. You pass the variant's ID to the step's filters and specify the fields to retrieve. To retrieve the variant's price based on the cart's context, you pass the cart's currency code to the `calculated_price` context. - -Next, you'll retrieve the variant's real-time price using the `getVariantMetalPricesStep` you created earlier. First, add the following import: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { - getVariantMetalPricesStep, - GetVariantMetalPricesStepInput, -} from "./steps/get-variant-metal-prices" -``` - -Then, replace the `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -const price = getVariantMetalPricesStep({ - variant: variants[0], - currencyCode: carts[0].currency_code, - quantity: item.quantity, -} as unknown as GetVariantMetalPricesStepInput) - -// TODO add item with custom price to cart -``` - -You execute the `getVariantMetalPricesStep` passing it the variant's details, the cart's currency code, and the quantity of the item to add to the cart. The step returns the variant's custom price. - -Next, you'll add the item with the custom price to the cart. First, add the following imports at the top of the file: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { transform } from "@medusajs/framework/workflows-sdk" -import { addToCartWorkflow } from "@medusajs/medusa/core-flows" -``` - -Then, replace the `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -const itemToAdd = transform({ - item, - price, -}, (data) => { - return [{ - ...data.item, - unit_price: data.price, - }] -}) - -addToCartWorkflow.runAsStep({ - input: { - items: itemToAdd, - cart_id, - }, -}) - -// TODO retrieve and return cart -``` - -You prepare the item to add to the cart using `transform` from the Workflows SDK. It allows you to manipulate and create variables in a workflow. After that, you use Medusa's `addToCartWorkflow` to add the item with the custom price to the cart. - -A workflow's constructor function has some constraints in implementation, which is why you need to use `transform` for variable manipulation. Learn more about these constraints in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). - -Lastly, you'll retrieve the cart's details again and return them. Add the following import at the beginning of the file: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { WorkflowResponse } from "@medusajs/framework/workflows-sdk" -``` - -And replace the last `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -// @ts-ignore -const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - filters: { id: cart_id }, - fields: ["id", "items.*"], -}).config({ name: "refetch-cart" }) - -return new WorkflowResponse({ - cart: updatedCarts[0], -}) -``` - -In the code above, you retrieve the updated cart's details using the `useQueryGraphStep` helper step. To return data from the workflow, you create and return a `WorkflowResponse` instance. It accepts as a parameter the data to return, which is the updated cart. - -In the next step, you'll use the workflow in a custom route to add an item with a custom price to the cart. - -*** - -## Step 4: Create Add Custom Item to Cart API Route - -Now that you've implemented the logic to add an item with a custom price to the cart, you'll expose this functionality in an API route. - -An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. You'll create an API route at the path `/store/carts/:id/line-items-metals` that executes the workflow from the previous step to add a product variant with custom price to the cart. - -Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). - -### 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`. So, to create the `/store/carts/:id/line-items-metals` API route, create the file `src/api/store/carts/[id]/line-items-metals/route.ts` with the following content: - -![The directory structure after adding the API route file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738252712/Medusa%20Resources/custom-item-price-6_deecbu.jpg) - -```ts title="src/api/store/carts/[id]/line-items-metals/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework" -import { HttpTypes } from "@medusajs/framework/types" -import { addCustomToCartWorkflow } from "../../../../../workflows/add-custom-to-cart" - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const { id } = req.params - const item = req.validatedBody - - const { result } = await addCustomToCartWorkflow(req.scope) - .run({ - input: { - cart_id: id, - item, - }, - }) - - res.status(200).json({ cart: result.cart }) -} -``` - -Since you export a `POST` function in this file, you're exposing a `POST` API route at `/store/carts/:id/line-items-metals`. The route handler function accepts two parameters: - -1. A request object with details and context on the request, such as path and body parameters. -2. A response object to manipulate and send the response. - -In the function, you retrieve the cart's ID from the path parameter, and the item's details from the request body. This API route will accept the same request body parameters as Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). - -Then, you execute the `addCustomToCartWorkflow` by invoking it, passing it the Medusa container, which is available in the request's `scope` property, then executing its `run` method. You pass the workflow's input object with the cart's ID and the item to add to the cart. - -Finally, you return a response with the updated cart's details. - -### Add Request Body Validation Middleware - -To ensure that the request body contains the required parameters, you'll add a middleware that validates the incoming request's body based on a defined schema. - -A middleware is a function executed before the API route when a request is sent to it. You define middlewares in Medusa in the `src/api/middlewares.ts` directory. - -Learn more about middlewares in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). - -To add a validation middleware to the custom API route, create the file `src/api/middlewares.ts` with the following content: - -![The directory structure after adding the middleware file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253099/Medusa%20Resources/custom-item-price-7_l7iw2a.jpg) - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { - StoreAddCartLineItem, -} from "@medusajs/medusa/api/store/carts/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/carts/:id/line-items-metals", - method: "POST", - middlewares: [ - validateAndTransformBody( - StoreAddCartLineItem - ), - ], - }, - ], -}) -``` - -In this file, you export the middlewares definition using `defineMiddlewares` from the Medusa Framework. This function accepts an object having a `routes` property, which is an array of middleware configurations to apply on routes. - -You pass in the `routes` array an object having the following properties: - -- `matcher`: The route to apply the middleware on. -- `method`: The HTTP method to apply the middleware on for the specified API route. -- `middlewares`: An array of the middlewares to apply. You apply the `validateAndTransformBody` middleware, which validates the request body based on the `StoreAddCartLineItem` schema. This validation schema is the same schema used for Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). - -Any request sent to the `/store/carts/:id/line-items-metals` API route will now fail if it doesn't have the required parameters. - -Learn more about API route validation in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/validation/index.html.md). - -### Prepare to Test API Route - -Before you test the API route, you'll prepare and retrieve the necessary data to add a product variant with a custom price to the cart. - -#### Create Product with Metal Variant - -You'll first create a product that has a `Metal` option, and variant(s) with values for this option. - -Start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Then, open the Medusa Admin dashboard at `localhost:9000/app` and log in with the email and password you created when you installed the Medusa application in the first step. - -Once you log in, click on Products in the sidebar, then click the Create button at the top right. - -![Click on Products in the sidebar at the left, then click on the Create button at the top right of the content](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253415/Medusa%20Resources/Screenshot_2025-01-30_at_6.09.36_PM_ee0jr2.png) - -Then, in the Create Product form: - -1. Enter a name for the product, and optionally enter other details like description. -2. Enable the "Yes, this is a product with variants" toggle. -3. Under Product Options, enter "Metal" for the title, and enter "Gold" for the values. - -Once you're done, click the Continue button. - -![Fill in the product details, enable the "Yes, this is a product with variants" toggle, and add the "Metal" option with "Gold" value](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253520/Medusa%20Resources/Screenshot_2025-01-30_at_6.11.29_PM_lqxth9.png) - -You can skip the next two steps by clicking the Continue button again, then the Publish button. - -Once you're done, the product's page will open. You'll now add weight to the product's Gold variant. To do that: - -- Scroll to the Variants section and find the Gold variant. -- Click on the three-dots icon at its right. -- Choose "Edit" from the dropdown. - -![Find the Gold variant in the Variants section, click on the three-dots icon, and choose "Edit"](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254038/Medusa%20Resources/Screenshot_2025-01-30_at_6.19.52_PM_j3hjcx.png) - -In the side window that opens, find the Weight field, enter the weight, and click the Save button. - -![Enter the weight in the Weight field, then click the Save button](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254165/Medusa%20Resources/Screenshot_2025-01-30_at_6.22.15_PM_yplzdp.png) - -Finally, you need to set fixed prices for the variant, even if they're just `0`. To do that: - -1. Click on the three-dots icon at the top right of the Variants section. -2. Choose "Edit Prices" from the dropdown. - -![Click on the three-dots icon at the top right of the Variants section, then choose "Edit Prices"](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255203/Medusa%20Resources/Screenshot_2025-01-30_at_6.39.35_PM_s3jpxh.png) - -For each cell in the table, either enter a fixed price for the specified currency or leave it as `0`. Once you're done, click the Save button. - -![Enter fixed prices for the variant in the table, then click the Save button](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255272/Medusa%20Resources/Screenshot_2025-01-30_at_6.40.45_PM_zw1l59.png) - -You'll use this variant to add it to the cart later. You can find its ID by clicking on the variant, opening its details page.

This ensures the request's operations are scoped to the publishable API key's associated sales channels. For example, products that aren't available in a cart's sales channel can't be added to it. - -To retrieve the publishable API key, on the Medusa Admin: - -1. Click on Settings in the sidebar at the bottom left. -2. Click on Publishable API Keys from the sidebar, then click on a publishable API key in the list. - -![Click on publishable API keys in the Settings sidebar, then click on a publishable API key in the list](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254523/Medusa%20Resources/Screenshot_2025-01-30_at_6.28.17_PM_mldscc.png) - -3. Click on the publishable API key to copy it. - -![Click on the publishable API key to copy it](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254601/Medusa%20Resources/Screenshot_2025-01-30_at_6.29.26_PM_vvatki.png) - -You'll use this key when you test the API route. - -### Test API Route - -To test out the API route, you need to create a cart. A cart must be associated with a region. So, to retrieve the ID of a region in your store, send a `GET` request to the `/store/regions` API route: - -```bash -curl 'localhost:9000/store/regions' \ --H 'x-publishable-api-key: {api_key}' -``` - -Make sure to replace `{api_key}` with the publishable API key you copied earlier. - -This will return a list of regions. Copy the ID of one of the regions. - -Then, send a `POST` request to the `/store/carts` API route to create a cart: - -```bash -curl -X POST 'localhost:9000/store/carts' \ --H 'x-publishable-api-key: {api_key}' \ --H 'Content-Type: application/json' \ ---data '{ - "region_id": "{region_id}" -}' -``` - -Make sure to replace `{api_key}` with the publishable API key you copied earlier, and `{region_id}` with the ID of a region from the previous request. - -This will return the created cart. Copy the ID of the cart to use it next. - -Finally, to add the Gold variant to the cart with a custom price, send a `POST` request to the `/store/carts/:id/line-items-metals` API route: - -```bash -curl -X POST 'localhost:9000/store/carts/{cart_id}/line-items-metals' \ --H 'x-publishable-api-key: {api_key}' \ --H 'Content-Type: application/json' \ ---data '{ - "variant_id": "{variant_id}", - "quantity": 1 -}' -``` - -Make sure to replace: - -- `{api_key}` with the publishable API key you copied earlier. -- `{cart_id}` with the ID of the cart you created. -- `{variant_id}` with the ID of the Gold variant you created. - -This will return the cart's details, where you can see in its `items` array the item with the custom price: - -```json title="Example Response" -{ - "cart": { - "items": [ - { - "variant_id": "{variant_id}", - "quantity": 1, - "is_custom_price": true, - // example custom price - "unit_price": 2000 - } - ] - } -} -``` - -The price will be the result of the calculation you've implemented earlier, which is the fixed price of the variant plus the real-time price of the metal, multiplied by the weight of the variant and the quantity added to the cart. - -This price will be reflected in the cart's total price, and you can proceed to checkout with the custom-priced item. - -*** - -## Next Steps - -You've now implemented custom item pricing in Medusa. You can also customize the [storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to use the new API route to add custom-priced items to the cart. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - # How-to & Tutorials In this section of the documentation, you'll find how-to guides and tutorials that will help you customize the Medusa server and admin.

Medusa provides a [SendGrid Notification Module Provider](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/notification/sendgrid/index.html.md) that you can use to send emails. - -Alternatively, you can use [other Notification Module Providers](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/infrastructure-modules/notification#what-is-a-notification-module-provider/index.html.md) or [create a custom provider](https://docs.medusajs.com/references/notification-provider-module/index.html.md). - -To set up SendGrid, add the SendGrid Notification Module Provider to `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/notification", - options: { - providers: [ - { - resolve: "@medusajs/medusa/notification-sendgrid", - id: "sendgrid", - options: { - channels: ["email"], - api_key: process.env.SENDGRID_API_KEY, - from: process.env.SENDGRID_FROM, - }, - }, - ], - }, - }, - ], -}) -``` - -In the `modules` configuration, you pass the Notification Provider and add SendGrid as a provider. You also pass to the SendGrid Module Provider the following options: - -- `channels`: The channels that the provider supports. In this case, it is only email. -- `api_key`: Your SendGrid API key. -- `from`: The email address that the emails will be sent from. - -Then, set the SendGrid API key and "from" email as environment variables, such as in the `.env` file at the root of your project: - -```plain -SENDGRID_API_KEY=your-sendgrid-api-key -SENDGRID_FROM=test@gmail.com -``` - -You can now use SendGrid to send emails in Medusa. - -*** - -## Step 3: Send Abandoned Cart Notification Flow - -You will now implement the sending logic for the abandoned cart notifications. - -To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it is a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in a scheduled job. - -In this step, you will create the workflow that sends the abandoned cart notifications. Later, you will learn how to execute it once a day. - -The workflow will receive the list of abandoned carts as an input. The workflow has the following steps: - -- [sendAbandonedNotificationsStep](#sendAbandonedNotificationsStep): Send the abandoned cart notifications. -- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to store the last notification date. - -Medusa provides the second step in its `@medusajs/medusa/core-flows` package. So, you only need to implement the first one. - -### sendAbandonedNotificationsStep - -The first step of the workflow sends a notification to the owners of the abandoned carts that are passed as an input. - -To implement the step, create the file `src/workflows/steps/send-abandoned-notifications.ts` with the following content: - -```ts title="src/workflows/steps/send-abandoned-notifications.ts" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { Modules } from "@medusajs/framework/utils" -import { CartDTO, CustomerDTO } from "@medusajs/framework/types" - -type SendAbandonedNotificationsStepInput = { - carts: (CartDTO & { - customer: CustomerDTO - })[] -} - -export const sendAbandonedNotificationsStep = createStep( - "send-abandoned-notifications", - async (input: SendAbandonedNotificationsStepInput, { container }) => { - const notificationModuleService = container.resolve( - Modules.NOTIFICATION - ) - - const notificationData = input.carts.map((cart) => ({ - to: cart.email!, - channel: "email", - template: process.env.ABANDONED_CART_TEMPLATE_ID || "", - data: { - customer: { - first_name: cart.customer?.first_name || cart.shipping_address?.first_name, - last_name: cart.customer?.last_name || cart.shipping_address?.last_name, - }, - cart_id: cart.id, - items: cart.items?.map((item) => ({ - product_title: item.title, - quantity: item.quantity, - unit_price: item.unit_price, - thumbnail: item.thumbnail, - })), - }, - })) - - const notifications = await notificationModuleService.createNotifications( - notificationData - ) - - return new StepResponse({ - notifications, - }) - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `create-review`. -2. An async function that receives two parameters: - - The step's input, which is in this case an object with the review's properties. - - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, you first resolve the Notification Module's service, which has methods to manage notifications. Then, you prepare the data of each notification, and create the notifications with the `createNotifications` method. - -Notice that each notification is an object with the following properties: - -- `to`: The email address of the customer. -- `channel`: The channel that the notification will be sent through. The Notification Module uses the provider registered for the channel. -- `template`: The ID or name of the email template in the third-party provider. Make sure to set it as an environment variable once you have it. -- `data`: The data to pass to the template to render the email's dynamic content. - -Based on the dynamic template you create in SendGrid or another provider, you can pass different data in the `data` object. - -A step function must return a `StepResponse` instance. The `StepResponse` constructor accepts the step's output as a parameter, which is the created notifications. - -### Create Workflow - -You can now create the workflow that uses the step you just created to send the abandoned cart notifications. - -Create the file `src/workflows/send-abandoned-carts.ts` with the following content: - -```ts title="src/workflows/send-abandoned-carts.ts" -import { - createWorkflow, - WorkflowResponse, - transform, -} from "@medusajs/framework/workflows-sdk" -import { - sendAbandonedNotificationsStep, -} from "./steps/send-abandoned-notifications" -import { updateCartsStep } from "@medusajs/medusa/core-flows" -import { CartDTO } from "@medusajs/framework/types" -import { CustomerDTO } from "@medusajs/framework/types" - -export type SendAbandonedCartsWorkflowInput = { - carts: (CartDTO & { - customer: CustomerDTO - })[] -} - -export const sendAbandonedCartsWorkflow = createWorkflow( - "send-abandoned-carts", - function (input: SendAbandonedCartsWorkflowInput) { - sendAbandonedNotificationsStep(input) - - const updateCartsData = transform( - input, - (data) => { - return data.carts.map((cart) => ({ - id: cart.id, - metadata: { - ...cart.metadata, - abandoned_notification: new Date().toISOString(), - }, - })) - } - ) - - const updatedCarts = updateCartsStep(updateCartsData) - - return new WorkflowResponse(updatedCarts) - } -) -``` - -You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. - -It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an arra of carts. - -In the workflow's constructor function, you: - -- Use the `sendAbandonedNotificationsStep` to send the notifications to the carts' customers. -- Use the `updateCartsStep` from Medusa's core flows to update the carts' metadata with the last notification date. - -Notice that you use the `transform` function to prepare the `updateCartsStep`'s input. Medusa does not support direct data manipulation in a workflow's constructor function. You can learn more about it in the [Data Manipulation in Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/variable-manipulation/index.html.md). - -Your workflow is now ready for use. You will learn how to execute it in the next section. - -### Setup Email Template - -Before you can test the workflow, you need to set up an email template in SendGrid. The template should contain the dynamic content that you pass in the workflow's step. - -To create an email template in SendGrid: - -- Go to [Dynamic Templates](https://mc.sendgrid.com/dynamic-templates) in the SendGrid dashboard. -- Click on the "Create Dynamic Template" button. - -![Button is at the top right of the page](https://res.cloudinary.com/dza7lstvk/image/upload/v1742457153/Medusa%20Resources/Screenshot_2025-03-20_at_9.51.38_AM_g5nk80.png) - -- In the side window that opens, enter a name for the template, then click on the Create button. -- The template will be added to the middle of the page. When you click on it, a new section will show with an "Add Version" button. Click on it. - -![The template is a collapsible in the middle of the page,with the "Add Version" button shown in the middle](https://res.cloudinary.com/dza7lstvk/image/upload/v1742458096/Medusa%20Resources/Screenshot_2025-03-20_at_10.07.54_AM_y2dys7.png) - -In the form that opens, you can either choose to start with a blank template or from an existing design. You can then use the drag-and-drop or code editor to design the email template. - -You can also use the following template as an example: - -```html title="Abandoned Cart Email Template" - - - - - - Complete Your Purchase - - - -
-
Hi {{customer.first_name}}, your cart is waiting! 🛍️
-

You left some great items in your cart. Complete your purchase before they're gone!

- - {{#each items}} -
- {{product_title}} -
- {{product_title}} -

{{subtitle}}

-

Quantity: {{quantity}}

-

Price: $ {{unit_price}}

-
-
- {{/each}} - - Return to Cart & Checkout -

-
- - -``` - -This template will show each item's image, title, quantity, and price in the cart. It will also show a button to return to the cart and checkout. - -You can replace `https://yourstore.com` with your storefront's URL. You'll later implement the `/cart/recover/:cart_id` route in the storefront to recover the cart. - -Once you are done, copy the template ID from SendGrid and set it as an environment variable in your Medusa project: - -```plain -ABANDONED_CART_TEMPLATE_ID=your-sendgrid-template-id -``` - -*** - -## Step 4: Schedule Cart Abandonment Notifications - -The next step is to automate sending the abandoned cart notifications. You need a task that runs once a day to find the carts that have been abandoned for a certain period and send the notifications to the customers. - -To run a task at a scheduled interval, you can use a [scheduled job](https://docs.medusajs.com/docs/learn/fundamentals/scheduled-jobs/index.html.md). A scheduled job is an asynchronous function that the Medusa application runs at the interval you specify during the Medusa application's runtime. - -You can create a scheduled job in a TypeScript or JavaScript file under the `src/jobs` directory. So, to create the scheduled job that sends the abandoned cart notifications, create the file `src/jobs/send-abandoned-cart-notification.ts` with the following content: - -```ts title="src/jobs/send-abandoned-cart-notification.ts" -import { MedusaContainer } from "@medusajs/framework/types" -import { - sendAbandonedCartsWorkflow, - SendAbandonedCartsWorkflowInput, -} from "../workflows/send-abandoned-carts" - -export default async function abandonedCartJob( - container: MedusaContainer -) { - const logger = container.resolve("logger") - const query = container.resolve("query") - - const oneDayAgo = new Date() - oneDayAgo.setDate(oneDayAgo.getDate() - 1) - const limit = 100 - const offset = 0 - const totalCount = 0 - const abandonedCartsCount = 0 - - do { - // TODO retrieve paginated abandoned carts - } while (offset < totalCount) - - logger.info(`Sent ${abandonedCartsCount} abandoned cart notifications`) -} - -export const config = { - name: "abandoned-cart-notification", - schedule: "0 0 * * *", // Run at midnight every day -} -``` - -In a scheduled job's file, you must export: - -1. An asynchronous function that holds the job's logic. The function receives the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md) as a parameter. -2. A `config` object that specifies the job's name and schedule. The schedule is a [cron expression](https://crontab.guru/) that defines the interval at which the job runs. - -In the scheduled job function, so far you resolve the [Logger](https://docs.medusajs.com/docs/learn/debugging-and-testing/logging/index.html.md) to log messages, and [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) to retrieve data across modules. - -You also define a `oneDayAgo` date, which is the date that you will use as the condition of an abandoned cart. In addition, you define variables to paginate the carts. - -Next, you will retrieve the abandoned carts using Query. Replace the `TODO` with the following: - -```ts title="src/jobs/send-abandoned-cart-notification.ts" -const { - data: abandonedCarts, - metadata, -} = await query.graph({ - entity: "cart", - fields: [ - "id", - "email", - "items.*", - "metadata", - "customer.*", - ], - filters: { - updated_at: { - $lt: oneDayAgo, - }, - // @ts-ignore - email: { - $ne: null, - }, - // @ts-ignore - completed_at: null, - }, - pagination: { - skip: offset, - take: limit, - }, -}) - -totalCount = metadata?.count ?? 0 -const cartsWithItems = abandonedCarts.filter((cart) => - cart.items?.length > 0 && !cart.metadata?.abandoned_notification -) - -try { - await sendAbandonedCartsWorkflow(container).run({ - input: { - carts: cartsWithItems, - } as unknown as SendAbandonedCartsWorkflowInput, - }) - abandonedCartsCount += cartsWithItems.length - -} catch (error) { - logger.error( - `Failed to send abandoned cart notification: ${error.message}` - ) -} - -offset += limit -``` - -In the do-while loop, you use Query to retrieve carts matching the following criteria: - -- The cart was last updated more than a day ago. -- The cart has an email address. -- The cart has not been completed. - -You also filter the retrieved carts to only include carts with items and customers that have not received an abandoned cart notification. - -Finally, you execute the `sendAbandonedCartsWorkflow` passing it the abandoned carts as an input. You will execute the workflow for each paginated batch of carts. - -### Test it Out - -To test out the scheduled job and workflow, it is recommended to change the `oneDayAgo` date to a minute before now for easy testing: - -```ts title="src/jobs/send-abandoned-cart-notification.ts" -oneDayAgo.setMinutes(oneDayAgo.getMinutes() - 1) // For testing -``` - -And to change the job's schedule in `config` to run every minute: - -```ts title="src/jobs/send-abandoned-cart-notification.ts" -export const config = { - // ... - schedule: "* * * * *", // Run every minute for testing -} -``` - -Finally, start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -And in the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md)'s directory (that you installed in the first step), start the storefront with the following command: - -```bash npm2yarn -npm run dev -``` - -Open the storefront at `localhost:8000`. You can either: - -- Create an account and add items to the cart, then leave the cart for a minute. -- Add an item to the cart as a guest. Then, start the checkout process, but only enter the shipping and email addresses, and leave the cart for a minute. - -Afterwards, wait for the job to execute. Once it is executed, you will see the following message in the terminal: - -```bash -info: Sent 1 abandoned cart notifications -``` - -Once you're done testing, make sure to revert the changes to the `oneDayAgo` date and the job's schedule. - -*** - -## Step 5: Recover Cart in Storefront - -In the storefront, you need to add a route that recovers the cart when the customer clicks on the link in the email. The route should receive the cart ID, set the cart ID in the cookie, and redirect the customer to the cart page. - -To implement the route, in the Next.js Starter Storefront create the file `src/app/[countryCode]/(main)/cart/recover/[id]/route.tsx` with the following content: - -```tsx title="src/app/[countryCode]/(main)/cart/recover/[id]/route.tsx" badgeLabel="Storefront" badgeColor="blue" -import { NextRequest } from "next/server" -import { retrieveCart } from "../../../../../../lib/data/cart" -import { setCartId } from "../../../../../../lib/data/cookies" -import { notFound, redirect } from "next/navigation" -type Params = Promise<{ - id: string -}> - -export async function GET(req: NextRequest, { params }: { params: Params }) { - const { id } = await params - const cart = await retrieveCart(id) - - if (!cart) { - return notFound() - } - - setCartId(id) - - const countryCode = cart.shipping_address?.country_code || - cart.region?.countries?.[0]?.iso_2 - - redirect( - `/${countryCode ? `${countryCode}/` : ""}cart` - ) -} -``` - -You add a `GET` route handler that receives the cart ID as a path parameter. In the route handler, you: - -- Try to retrieve the cart from the Medusa application. The `retrieveCart` function is already available in the Next.js storefront. If the cart is not found, you return a 404 response. -- Set the cart ID in a cookie using the `setCartId` function. This is also a function that is already available in the storefront. -- Redirect the customer to the cart page. You set the country code in the URL based on the cart's shipping address or region. - -### Test it Out - -To test it out, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -And in the Next.js Starter Storefront's directory, start the storefront: - -```bash npm2yarn -npm run dev -``` - -Then, either open the link in an abandoned cart email or navigate to `localhost:8000/cart/recover/:cart_id` in your browser. You will be redirected to the cart page with the recovered cart. - -![Cart page in the storefront](https://res.cloudinary.com/dza7lstvk/image/upload/v1742459552/Medusa%20Resources/Screenshot_2025-03-20_at_10.32.17_AM_frmbup.png) - -*** - -## Next Steps - -You have now implemented the logic to send abandoned cart notifications in Medusa. You can implement other customizations with Medusa, such as: - -- [Implement Product Reviews](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/how-to-tutorials/tutorials/product-reviews/index.html.md). -- [Implement Wishlist](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/plugins/guides/wishlist/index.html.md). -- [Allow Custom-Item Pricing](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/examples/guides/custom-item-price/index.html.md). - -If you are new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you will get a more in-depth learning of all the concepts you have used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - -# Implement Product Reviews in Medusa - -In this tutorial, you'll learn how to implement product reviews in Medusa. - -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. The features include product-management features. - -Medusa doesn't provide product reviews out-of-the-box, but the Medusa Framework facilitates implementing customizations like product reviews. In this tutorial, you'll learn how to customize the Medusa server, Admin dashboard, and Next.js Starter Storefront to implement product reviews. - -You can follow this guide whether you're new to Medusa or an advanced Medusa developer. - -## Summary - -By following this tutorial, you'll learn how to: - -- Install and set up Medusa. -- Define product reviews models and implement their management features in the Medusa server. -- Customize the Medusa Admin to allow merchants to view and manage product reviews. -- Customize the Next.js storefront to display product reviews and allow customers to submit reviews. - -![Diagram showcasing the product review features in the storefront and admin](https://res.cloudinary.com/dza7lstvk/image/upload/v1741941058/Medusa%20Resources/reviews-overview_nufybf.jpg) - -- [Product Reviews Repository](https://github.com/medusajs/examples/tree/main/product-reviews): Find the full code for this guide in this repository. -- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1741941475/OpenApi/product-reviews_jh8ohj.yaml): Import this OpenApi Specs file into tools like Postman. - -*** - -## Step 1: Install a Medusa Application - -### Prerequisites - -- [Node.js v20+](https://nodejs.org/en/download) -- [Git CLI tool](https://git-scm.com/downloads) -- [PostgreSQL](https://www.postgresql.org/download/) - -Start by installing the Medusa application on your machine with the following command: - -```bash -npx create-medusa-app@latest -``` - -You'll first be asked for the project's name. Then, when asked whether you want to install the [Next.js starter storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md), choose Yes. - -Afterwards, 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. Afterwards, 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: Add Product Review Module - -In Medusa, you can build custom features in a [module](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. - -In the module, you define the data models necessary for a feature and the logic to manage these data models. Later, you can build commerce flows around your module. - -In this step, you'll build a Product Review Module that defines the necessary data models to store and manage product reviews. - -Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. - -### Create Module Directory - -A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/review`. - -### Create Data Models - -A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -Refer to the [Data Models documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#1-create-data-model/index.html.md) to learn more. - -For the Product Review Module, you need to define a `Review` data model that represents a product review. So, create the file `src/modules/review/models/review.ts` with the following content: - -```ts title="src/modules/review/models/review.ts" -import { model } from "@medusajs/framework/utils" - -const Review = model.define("review", { - id: model.id().primaryKey(), - title: model.text().nullable(), - content: model.text(), - rating: model.float(), - first_name: model.text(), - last_name: model.text(), - status: model.enum(["pending", "approved", "rejected"]).default("pending"), - product_id: model.text().index("IDX_REVIEW_PRODUCT_ID"), - customer_id: model.text().nullable(), -}) -.checks([ - { - name: "rating_range", - expression: (columns) => `${columns.rating} >= 1 AND ${columns.rating} <= 5`, - }, -]) - -export default Review -``` - -You define the `Review` data model using the `model.define` method of the DML. It accepts the data model's table name as a first parameter, and the model's schema object as a second parameter. - -The `Review` data model has the following properties: - -- `id`: A unique ID for the review. -- `title`: The review's title. -- `content`: The review's content. -- `rating`: The review's rating. You also add a [check constraint](https://docs.medusajs.com/docs/learn/fundamentals/data-models/check-constraints/index.html.md) to ensure the rating is between 1 and 5. -- `first_name`: The first name of the reviewer. -- `last_name`: The last name of the reviewer. -- `status`: The review's status, which can be `pending`, `approved`, or `rejected`. -- `product_id`: The ID of the product the review is for. -- `customer_id`: The ID of the customer who submitted the review. - -Learn more about defining data model properties in the [Property Types documentation](https://docs.medusajs.com/docs/learn/fundamentals/data-models/properties/index.html.md). - -### Create Module's Service - -You now have the necessary data model in the Review Module, but you'll need to manage its records. You do this by creating a service in the module. - -A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, allowing you to manage your data models, or connect to a third-party service, which is useful if you're integrating with external services. - -Refer to the [Module Service documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#2-create-service/index.html.md) to learn more. - -To create the Review Module's service, create the file `src/modules/review/service.ts` with the following content: - -```ts title="src/modules/review/service.ts" -import { MedusaService } from "@medusajs/framework/utils" -import Review from "./models/review" - -class ProductReviewModuleService extends MedusaService({ - Review, -}) { -} - -export default ProductReviewModuleService -``` - -The `ProductReviewModuleService` extends `MedusaService` from the Modules SDK which generates a class with data-management methods for your module's data models. This saves you time on implementing Create, Read, Update, and Delete (CRUD) methods. - -So, the `ProductReviewModuleService` class now has methods like `createReviews` and `retrieveReview`. - -Find all methods generated by the `MedusaService` in [the Service Factory reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/service-factory-reference/index.html.md). - -You'll use this service later when you implement custom flows for product reviews. - -### 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/review/index.ts` with the following content: - -```ts title="src/modules/review/index.ts" -import { Module } from "@medusajs/framework/utils" -import ProductReviewModuleService from "./service" - -export const PRODUCT_REVIEW_MODULE = "productReview" - -export default Module(PRODUCT_REVIEW_MODULE, { - service: ProductReviewModuleService, -}) -``` - -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 `productReview`. -2. An object with a required property `service` indicating the module's service. - -You also export the module's name as `PRODUCT_REVIEW_MODULE` so you can reference it later. - -### Add Module to Medusa's Configurations - -Once you finish building the module, add it to Medusa's configurations to start using it. - -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/product-review", - }, - ], -}) -``` - -Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. - -### Generate Migrations - -Since data models represent tables in the database, you define how they're created in the database with migrations. A migration is a TypeScript or JavaScript file that defines database changes made by a module. - -Refer to the [Migrations documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#5-generate-migrations/index.html.md) to learn more. - -Medusa's CLI tool can generate the migrations for you. To generate a migration for the Review Module, run the following command in your Medusa application's directory: - -```bash -npx medusa db:generate review -``` - -The `db:generate` command of the Medusa CLI accepts the name of the module to generate the migration for. You'll now have a `migrations` directory under `src/modules/review` that holds the generated migration. - -Then, to reflect these migrations on the database, run the following command: - -```bash -npx medusa db:migrate -``` - -The table for the `Review` data model is now created in the database. - -*** - -## Step 3: Define Review \<> Product Link - -When you defined the `Review` data model, you added properties that store the ID of records managed by other modules. For example, the `product_id` property stores the ID of the product this review is for, but products are managed by the [Product Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/index.html.md). - -Medusa integrates modules into your application without implications or side effects by isolating modules from one another. This means you can't directly create relationships between data models in your module and data models in other modules. - -Instead, Medusa provides the mechanism to define links between data models, and retrieve and manage linked records while maintaining module isolation. Links are useful to define associations between data models in different modules, or extend a model in another module to associate custom properties with it. - -Refer to the [Module Isolation documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/isolation/index.html.md) to learn more. - -In this step, you'll define a link between the Product Review Module's `Review` data model, and the Product Module's `Product` data model. You'll then use this link to retrieve the product associated with a review. - -You can also define a link between the `Review` data model and the `Customer` data model to retrieve the customer who submitted the review in a similar manner. - -You can define links between data models in a TypeScript or JavaScript file under the `src/links` directory. So, create the file `src/links/review-product.ts` with the following content: - -```ts title="src/links/review-product.ts" -import { defineLink } from "@medusajs/framework/utils" -import ProductReviewModule from "../modules/product-review" -import ProductModule from "@medusajs/medusa/product" - -export default defineLink( - { - linkable: ProductReviewModule.linkable.review, - field: "product_id", - isList: false, - }, - ProductModule.linkable.product, - { - readOnly: true, - } -) -``` - -You define a link using the `defineLink` function from the Modules SDK. It accepts three parameters: - -1. An object indicating the first data model part of the link. A module has a special `linkable` property that contains link configurations for its data models. So, you can pass the link configurations for the `Review` data model from the Product Review module, specifying that its `product_id` property holds the ID of the linked record. You also specify `isList` as `false` since a review can only have one product. -2. An object indicating the second data model part of the link. You pass the linkable configurations of the Product Module's `Product` data model. -3. An optional object with additional configurations for the link. By default, Medusa creates a table in the database to represent the link you define. However, when you only want to retrieve the linked records without managing and storing the links, you can set the `readOnly` option to `true`. - -You can now retrieve the product of a review, as you'll see in later steps. - -*** - -## Step 4: Create Review Workflow - -You're now ready to start implementing product-review features. The first one you'll implement is the ability for customers to create a product review. - -To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. - -So, in this section, you'll learn how to create a workflow that creates a review. Later, you'll execute this workflow in an API route. - -Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the product to confirm it exists. -- [createReviewStep](#createReviewStep): Create the review. - -The `useQueryGraphStep` step is provided by Medusa in its `@medusajs/medusa/core-flows` package. So, you only need to implement the `createReviewStep` step. - -### createReviewStep - -In the second step of the workflow, you create the review. To create a step, create the file `src/workflows/steps/create-review.ts` with the following content: - -```ts title="src/workflows/steps/create-review.ts" highlights={createReviewHighlights} -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { PRODUCT_REVIEW_MODULE } from "../../modules/product-review" -import ProductReviewModuleService from "../../modules/product-review/service" - -export type CreateReviewStepInput = { - title?: string - content: string - rating: number - product_id: string - customer_id?: string - first_name: string - last_name: string - status?: "pending" | "approved" | "rejected" -} - -export const createReviewStep = createStep( - "create-review", - async (input: CreateReviewStepInput, { container }) => { - const reviewModuleService: ProductReviewModuleService = container.resolve( - PRODUCT_REVIEW_MODULE - ) - - const review = await reviewModuleService.createReviews(input) - - return new StepResponse(review, review.id) - }, - async (reviewId, { container }) => { - if (!reviewId) { - return - } - - const reviewModuleService: ProductReviewModuleService = container.resolve( - PRODUCT_REVIEW_MODULE - ) - - await reviewModuleService.deleteReviews(reviewId) - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `create-review`. -2. An async function that receives two parameters: - - The step's input, which is in this case an object with the review's properties. - - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, you resolve the Review Module's service from the Medusa container using its `resolve` method, passing it the module's name as a parameter. - -Then, you create the review using the `createReview` method. As you remember, the Review Module's service extends the `MedusaService` which generates data-management methods for you. - -A step function must return a `StepResponse` instance. The `StepResponse` constructor accepts two parameters: - -1. The step's output, which is the review created. -2. Data to pass to the step's compensation function. - -#### Compensation Function - -The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. - -The compensation function accepts two parameters: - -1. The data passed from the step in the second parameter of `StepResponse`, which in this case is the ID of the created review. -2. An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). - -In the compensation function, you resolve the Review Module's service from the Medusa container and call the `deleteReviews` method to delete the review created in the step. - -### Add createReviewWorkflow - -You can now create the workflow using the step provided by Medusa and your custom step. - -To create the workflow, create the file `src/workflows/create-review.ts` with the following content: - -```ts title="src/workflows/create-review.ts" -import { - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { createReviewStep } from "./steps/create-review" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" - -type CreateReviewInput = { - title?: string - content: string - rating: number - product_id: string - customer_id?: string - first_name: string - last_name: string - status?: "pending" | "approved" | "rejected" -} - -export const createReviewWorkflow = createWorkflow( - "create-review", - (input: CreateReviewInput) => { - // Check product exists - // @ts-ignore - useQueryGraphStep({ - entity: "product", - fields: ["id"], - filters: { - id: input.product_id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - // Create the review - const review = createReviewStep(input) - - // @ts-ignore - return new WorkflowResponse({ - review, - }) - } -) -``` - -You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. - -It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an object of the review's details. - -In the workflow's constructor function, you: - -- use `useQueryGraphStep` to retrieve the product. By setting the `options.throwIfKeyNotFound` to `true`, the step throws an error if the product doesn't exist. -- Call the `createReviewStep` step to create the review. - -`useQueryGraphStep` uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which allows you to retrieve data across modules. For example, in the above snippet you're retrieving the cart's promotions, which are managed in the [Promotion Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/index.html.md), by passing `promotions.code` to the `fields` array. - -A workflow must return an instance of `WorkflowResponse`. The `WorkflowResponse` constructor accepts the workflow's output as a parameter, which is an object holding the created review in this case. - -In the next step, you'll learn how to execute this workflow in an API route. - -*** - -## Step 5: Create Review API Route - -Now that you have the logic to create a product review, you need to expose it so that frontend clients, such as a storefront, can use it. You do this 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, such as storefronts. You'll create an API route at the path `/store/reviews` that executes the workflow from the previous step. - -Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). - -### Implement 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`. - -So, to create an API route at the path `/store/reviews`, create the file `src/api/store/reviews/route.ts` with the following content: - -```ts title="src/api/store/reviews/route.ts" highlights={PostStoreReviewHighlights} -import type { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { createReviewWorkflow } from "../../../workflows/create-review" - -import { z } from "zod" - -export const PostStoreReviewSchema = z.object({ - title: z.string().optional(), - content: z.string(), - rating: z.preprocess( - (val) => { - if (val && typeof val === "string") { - return parseInt(val) - } - return val - }, - z.number().min(1).max(5) - ), - product_id: z.string(), - first_name: z.string(), - last_name: z.string(), -}) - -type PostStoreReviewReq = z.infer - -export const POST = async ( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) => { - const input = req.validatedBody - - const { result } = await createReviewWorkflow(req.scope) - .run({ - input: { - ...input, - customer_id: req.auth_context?.actor_id, - }, - }) - - res.json(result) -} -``` - -You first define a [Zod](https://zod.dev/) schema for the request body of the API route. You'll later use this schema to enforce validation on the API route. - -Then, since you export a `POST` function, you're exposing a `POST` API route at the path `/store/reviews`. 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. - -`AuthenticatedMedusaRequest` accepts the request body's type as a type argument. - -In the route handler, you execute the `createReviewWorkflow` workflow by invoking it, passing it the Medusa container (which is stored in the `scope` property of a request object). Then, you call its `run` method, passing to the workflow the request body as input. - -### Apply Validation and Authentication Middlewares - -Now that you have the API route, you need to enforce validation of the request body, and require authentication to access the route. You can do this with a middleware. A middleware is a function executed when a request is sent to an API Route. It's executed before the route handler. - -Learn more about middleware in the [Middlewares documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). - -Middlewares are created in the `src/api/middlewares.ts` file. So create the file `src/api/middlewares.ts` with the following content: - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - authenticate, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { PostStoreReviewSchema } from "./store/reviews/route" - - -export default defineMiddlewares({ - routes: [ - { - method: ["POST"], - matcher: "/store/reviews", - middlewares: [ - authenticate("customer", ["session", "bearer"]), - validateAndTransformBody(PostStoreReviewSchema), - ], - }, - ], -}) -``` - -To export the middlewares, you use the `defineMiddlewares` function. It accepts an object having a `routes` property, whose value is an array of middleware route objects. Each middleware route object has the following properties: - -- `method`: The HTTP methods the middleware applies to, which is in this case `POST`. -- `matcher`: The path of the route the middleware applies to. -- `middlewares`: An array of middleware functions to apply to the route. In this case, you apply two middlewares: - - `authenticate`: ensures the request is authenticated as a customer with a session or bearer token. - - `validateAndTransformBody`: validates that the request body parameters match the Zod schema passed as a parameter. - -The create product review route is now ready for use. - -### Test the API Route - -To test out the API route, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Then, open the Medusa Admin dashboard at `http://localhost:9000/app` and login using the credentials you set up earlier. - -#### Retrieve Publishable API Key - -All requests sent to routes starting with `/store` must have a publishable API key in their header. This ensures that the request is scoped to a specific sales channel of your storefront. - -To learn more about publishable API keys, refer to the [Publishable API Key documentation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/publishable-api-keys/index.html.md). - -To retrieve the publishable API key from the Medusa Admin, refer to [this user guide](https://docs.medusajs.com/user-guide/settings/developer/publishable-api-keys/index.html.md). - -#### Retrieve Customer Authentication Token - -As mentioned before, the API route you added requires the customer to be authenticated. So, you'll first create a customer, then retrieve their authentication token to use in the request. - -Before creating the customer, retrieve a registration token using the [Retrieve Registration JWT Token API route](https://docs.medusajs.com/api/store#auth_postactor_typeauth_provider_register): - -```bash -curl -X POST 'http://localhost:9000/auth/customer/emailpass/register' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "customer@gmail.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password with the credentials you want. - -Then, register the customer using the [Create Customer API route](https://docs.medusajs.com/api/store#customers_postcustomers): - -```bash -curl -X POST 'http://localhost:9000/store/customers' \ --H 'Authorization: Bearer {token}' \ --H 'Content-Type: application/json' \ --H 'x-publishable-api-key: {your_publishable_api_key}' \ ---data-raw '{ - "email": "customer@gmail.com" -}' -``` - -Make sure to replace: - -- `{token}` with the registration token you received from the previous request. -- `{your_publishable_api_key}` with the publishable API key you retrieved from the Medusa Admin. - -Also, if you changed the email in the first request, make sure to change it here as well. - -The customer is now registered. Lastly, you need to retrieve its authenticated token by sending a request to the [Authenticate Customer API route](https://docs.medusajs.com/api/store#auth_postactor_typeauth_provider): - -```bash -curl -X POST 'http://localhost:9000/auth/customer/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "customer@gmail.com", - "password": "supersecret" -}' -``` - -Copy the returned token to use it in the next requests. - -#### Retrieve Product ID - -Before creating a review, you need the ID of a product. You can either copy one from the Medusa Admin, or send the following request: - -```bash -curl 'http://localhost:9000/store/products' \ --H 'x-publishable-api-key: {your_publishable_api_key}' -``` - -Make sure to replace `{your_publishable_api_key}` with the publishable API key you retrieved from the Medusa Admin. - -#### Create a Review - -You can now create a review for the product you chose. To do that, send the following request: - -```bash -curl --location 'http://localhost:9000/store/reviews' \ ---header 'x-publishable-api-key: {your_publishable_api_key}' \ ---header 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "product_id": "{product_id}", - "title": "Really good", - "content": "The material is nice", - "rating": 5, - "first_name": "John", - "last_name": "Smith" -}' -``` - -Make sure to replace: - -- `{your_publishable_api_key}` with the publishable API key you retrieved from the Medusa Admin. -- `{token}` with the authentication token you retrieved from the previous request. -- `{product_id}` with the ID of the product you chose. - -If the request is successful, you'll receive a response with the created review. Notice that the review is in the `pending` status. In the upcoming steps, you'll allow admin users to approve or reject reviews. - -*** - -## Step 6: List Reviews Admin API Route - -In this step, you'll create an API route that lists the reviews of a product. You'll use this route in the Medusa Admin customizations to allow admin users to view and manage product reviews. - -### Create API Route - -To create the API route that retrieves a paginated list of reviews, create the file `src/api/admin/reviews/route.ts` with the following content: - -```ts title="src/api/admin/reviews/route.ts" highlights={GetAdminReviewsHighlights} -import { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { createFindParams } from "@medusajs/medusa/api/utils/validators" - -export const GetAdminReviewsSchema = createFindParams() - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const query = req.scope.resolve("query") - - const { - data: reviews, - metadata: { count, take, skip } = { - count: 0, - take: 20, - skip: 0, - }, - } = await query.graph({ - entity: "review", - ...req.queryConfig, - }) - - res.json({ - reviews, - count, - limit: take, - offset: skip, - }) -} -``` - -You first define a `GetAdminReviewsSchema` schema that will allow clients to pass the following query parameters: - -- `limit`: The number of reviews to retrieve. -- `offset`: The number of items to skip before retrieving the reviews. -- `order`: The fields to sort the reviews by in ascending or descending order. - -Then, you export a `GET` function, which exposes a `GET` API Route at the path `/admin/reviews`. In the route handler you resolve [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) from the Medusa container, which allows you to retrieve data across modules. - -Next, you retrieve all reviews using Query. Notice that you pass in `query.graph` the `req.queryConfig` object. This object holds the fields to retrieve and the pagination configurations. - -Finally, you return the reviews with pagination fields. - -### Apply Query Configurations Middleware - -After adding the API route, you need to add a middleware that validates the query parameters passed to the request, and sets the default Query configurations. - -Routes starting with `/admin` are protected by default. So, you don't need to add the `authenticate` middleware to enforce authentication. - -In `src/api/middlewares.ts`, add a new middleware: - -```ts title="src/api/middlewares.ts" -// other imports... -import { - validateAndTransformQuery, -} from "@medusajs/framework/http" -import { GetAdminReviewsSchema } from "./admin/reviews/route" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/admin/reviews", - method: ["GET"], - middlewares: [ - validateAndTransformQuery(GetAdminReviewsSchema, { - isList: true, - defaults: [ - "id", - "title", - "content", - "rating", - "product_id", - "customer_id", - "status", - "created_at", - "updated_at", - "product.*", - ], - }), - ], - }, - ], -}) -``` - -You use the `validateAndTransformQuery` middleware to enforce validation on the query parameters passed to the request. The middleware accepts two parameters: - -- The Zod schema to validate the query parameters, which is the `GetAdminReviewsSchema` schema you defined earlier. -- The Query configurations, which is an object with the following properties: - - `isList`: A boolean that indicates whether the query is a list query. - - `defaults`: An array of fields to retrieve by default. - -You'll test the API route as you customize the Medusa Admin in the next step. - -You pass `product.*` in the fields to retrieve, allowing you to retrieve the product associated with each review. This is possible because you defined a link between the `Review` data model and the `Product` data model in a previous step. - -*** - -## Step 7: Add Reviews UI Route - -Now that you have an API route that retrieves reviews, you'll customize the Medusa Admin to add a new "Reviews" page by creating a [UI Route](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md). - -A UI route is a React component that specifies the content to be shown in a new page in the Medusa Admin dashboard. You'll create a UI route to display the list of reviews in the Medusa Admin. - -Learn more about UI routes in the [UI Routes documentation](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md). - -### Configure JS SDK - -Medusa provides a [JS SDK](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md) that you can use to send requests to the Medusa server from any client application, including your Medusa Admin customizations. - -The JS SDK is installed by default in your Medusa application. To configure it, create the file `src/admin/lib/sdk.ts` with the following content: - -```ts title="src/admin/lib/sdk.ts" -import Medusa from "@medusajs/js-sdk" - -export const sdk = new Medusa({ - baseUrl: "http://localhost:9000", - debug: process.env.NODE_ENV === "development", - auth: { - type: "session", - }, -}) -``` - -You create an instance of the JS SDK using the `Medusa` class from the JS SDK. You pass it an object having the following properties: - -- `baseUrl`: The base URL of the Medusa server. -- `debug`: A boolean indicating whether to log debug information into the console. -- `auth`: An object specifying the authentication type. When using the JS SDK for admin customizations, you use the `session` authentication type. - -### Create UI Route - -You'll now create the UI Route that lists the reviews. To do this, create the file `src/admin/routes/reviews/page.tsx` with the following content: - -```tsx title="src/admin/routes/reviews/page.tsx" highlights={listUIRoutesHighlight1} collapsibleLines="1-18" expandButtonLabel="Show Imports" -import { defineRouteConfig } from "@medusajs/admin-sdk" -import { ChatBubbleLeftRight } from "@medusajs/icons" -import { - createDataTableColumnHelper, - Container, - DataTable, - useDataTable, - Heading, - StatusBadge, - Toaster, - DataTablePaginationState, -} from "@medusajs/ui" -import { useQuery } from "@tanstack/react-query" -import { useMemo, useState } from "react" -import { sdk } from "../../lib/sdk" -import { HttpTypes } from "@medusajs/framework/types" -import { Link } from "react-router-dom" - -type Review = { - id: string - title?: string - content: string - rating: number - product_id: string - customer_id?: string - status: "pending" | "approved" | "rejected" - created_at: Date - updated_at: Date - product?: HttpTypes.AdminProduct - customer?: HttpTypes.AdminCustomer -} - - -const columnHelper = createDataTableColumnHelper() - -const columns = [ - columnHelper.accessor("id", { - header: "ID", - }), - columnHelper.accessor("title", { - header: "Title", - }), - columnHelper.accessor("rating", { - header: "Rating", - }), - columnHelper.accessor("content", { - header: "Content", - }), - columnHelper.accessor("status", { - header: "Status", - cell: ({ row }) => { - const color = row.original.status === "approved" ? - "green" : row.original.status === "rejected" - ? "red" : "grey" - return ( - - {row.original.status.charAt(0).toUpperCase() + row.original.status.slice(1)} - - ) - }, - }), - columnHelper.accessor("product", { - header: "Product", - cell: ({ row }) => { - return ( - - {row.original.product?.title} - - ) - }, - }), -] - -// TODO add component -``` - -Before defining the component, you define a `Review` type, then define the columns of the table you'll show on the page. - -To display the table, you'll use the [DataTable](https://docs.medusajs.com/ui/components/data-table/index.html.md) component from Medusa UI. To define the columns of the table, you use the `createDataTableColumnHelper` function from Medusa UI, which returns a `columnHelper` object. You then use the `columnHelper` object to define the table's columns. - -Next, you'll add the component that renders the content of the page. Replace the `TODO` with the following: - -```tsx title="src/admin/routes/reviews/page.tsx" highlights={reviewsPageHighlights} -const limit = 15 - -const ReviewsPage = () => { - const [pagination, setPagination] = useState({ - pageSize: limit, - pageIndex: 0, - }) - - const offset = useMemo(() => { - return pagination.pageIndex * limit - }, [pagination]) - - const { data, isLoading, refetch } = useQuery<{ - reviews: Review[] - count: number - limit: number - offset: number - }>({ - queryKey: ["reviews", offset, limit], - queryFn: () => sdk.client.fetch("/admin/reviews", { - query: { - offset: pagination.pageIndex * pagination.pageSize, - limit: pagination.pageSize, - order: "-created_at", - }, - }), - }) - - const table = useDataTable({ - columns, - data: data?.reviews || [], - rowCount: data?.count || 0, - isLoading, - pagination: { - state: pagination, - onPaginationChange: setPagination, - }, - getRowId: (row) => row.id, - }) - - return ( - - - - - Reviews - - - - - - - - ) -} - -export const config = defineRouteConfig({ - label: "Reviews", - icon: ChatBubbleLeftRight, -}) - -export default ReviewsPage -``` - -You create a `ReviewPage` component, which holds the UI route's content. In the component, you: - -- Define state variables to configure pagination. -- Use the `useQuery` hook from `@tanstack/react-query` to fetch the reviews from the API route. In the query function, you use the JS SDK to send a request to the `/admin/reviews` API route. The JS SDK has a `client.fetch` method that has a similar signature to JavaScript's [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API). You can use it to send requests to custom routes. -- Use the `useDataTable` hook from Medusa UI to create a DataTable instance. You pass the columns, data, and pagination configurations to the hook. -- Render the DataTable component, passing the DataTable instance to the `instance` prop. You also render the DataTable's toolbar, table, and pagination components. - -The file also exports a configuration object created with `defineRouteConfig`. You export this object to tell Medusa that you want to add the new route to the Medusa Admin's sidebar. You specify the sidebar's item and title. - -### Test the UI Route - -To test out the UI route, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Then, open the Medusa Admin dashboard at `http://localhost:9000/app` and login using the credentials you set up earlier. - -You'll find a new sidebar item `Review`. Click on it to view the list of reviews. In the upcoming steps, you'll add functionality to approve or reject reviews. - -![Reviews page showing list of reviews](https://res.cloudinary.com/dza7lstvk/image/upload/v1741935325/Medusa%20Resources/Screenshot_2025-03-14_at_8.54.14_AM_tfhnyu.png) - -*** - -## Step 8: Change Review Status API Route - -Next, you want to allow the admin user to approve or reject reviews. To do this, you'll create a workflow that updates a review's status, then use it in an API route that exposes the functionality. - -### Update Review Step - -The workflow to update a review's status will have on step that updates the review. To create the step, create the file `src/workflows/steps/update-review.ts` with the following content: - -```ts title="src/workflows/steps/update-review.ts" highlights={updateReviewStepHighlights} -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { PRODUCT_REVIEW_MODULE } from "../../modules/product-review" -import ProductReviewModuleService from "../../modules/product-review/service" - -export type UpdateReviewsStepInput = { - id: string - status: "pending" | "approved" | "rejected" -}[] - -export const updateReviewsStep = createStep( - "update-review-step", - async (input: UpdateReviewsStepInput, { container }) => { - const reviewModuleService: ProductReviewModuleService = container.resolve( - PRODUCT_REVIEW_MODULE - ) - - // Get original review before update - const originalReviews = await reviewModuleService.listReviews({ - id: input.map((review) => review.id), - }) - - const reviews = await reviewModuleService.updateReviews(input) - - return new StepResponse(reviews, originalReviews) - }, - async (originalData, { container }) => { - if (!originalData) { - return - } - - const reviewModuleService: ProductReviewModuleService = container.resolve( - PRODUCT_REVIEW_MODULE - ) - - // Restore original review status - await reviewModuleService.updateReviews(originalData) - } -) -``` - -This step receives an array of objects, each with the ID of the review to update and its new status. - -In the step function, you first retrieve the original reviews before the update. Then, you update the reviews using the `updateReviews` method of the Review Module's service. - -After that, you return the updated reviews, and you pass the original reviews to the compensation function. - -In the compensation function, you restore the original reviews' status if an error occurs. - -### Update Review Workflow - -You can now create the workflow that uses the above step to update the review. To create the workflow, create the file `src/workflows/update-review.ts` with the following content: - -```ts title="src/workflows/update-review.ts" -import { - createWorkflow, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { updateReviewsStep } from "./steps/update-review" - -export type UpdateReviewInput = { - id: string - status: "pending" | "approved" | "rejected" -}[] - -export const updateReviewWorkflow = createWorkflow( - "update-review", - (input: UpdateReviewInput) => { - const reviews = updateReviewsStep(input) - - return new WorkflowResponse({ - reviews, - }) - } -) -``` - -The workflow receives an array of objects, each with the ID of the review to update and its new status. It uses the `updateReviewsStep` to update the reviews, then returns the updated reviews. - -### Create API Route - -Next, you'll create the API route that exposes the workflow's functionality. Create the file `src/api/admin/reviews/status/route.ts` with the following content: - -```ts title="src/api/admin/reviews/status/route.ts" highlights={PostAdminUpdateReviewsStatusHighlights} -import type { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { updateReviewWorkflow } from "../../../../workflows/update-review" -import { z } from "zod" - -export const PostAdminUpdateReviewsStatusSchema = z.object({ - ids: z.array(z.string()), - status: z.enum(["pending", "approved", "rejected"]), -}) - -export async function POST( - req: MedusaRequest>, - res: MedusaResponse -) { - const { ids, status } = req.validatedBody - - const { result } = await updateReviewWorkflow(req.scope).run({ - input: ids.map((id) => ({ - id, - status, - })), - }) - - res.json(result) -} -``` - -You first define a Zod schema for the request body of the API route. You'll later use this schema to enforce validation on the API route. The request body must include the following parameters: - -- `ids`: An array of review IDs to update. -- `status`: The new status to set for the reviews. - -Then, since you export a `POST` function, you're exposing a `POST` API route at the path `/admin/reviews/status`. In the route handler you execute the `updateReviewWorkflow` workflow, passing it the data from the request body. - -Finally, you return the updated reviews. - -### Apply Validation Middlewares - -The last step is to add the validation middleware that enforces validation the body parameters of requests sent to the API route. - -In `src/api/middlewares.ts`, add a new middleware: - -```ts title="src/api/middlewares.ts" -// other imports... -import { PostAdminUpdateReviewsStatusSchema } from "./admin/reviews/status/route" - -export default defineMiddlewares({ - routes: [ - // ... - { - matcher: "/admin/reviews/status", - method: ["POST"], - middlewares: [ - validateAndTransformBody(PostAdminUpdateReviewsStatusSchema), - ], - }, - ], -}) -``` - -You use the `validateAndTransformBody` middleware to enforce validation on an incoming request's body parameters. You pass the Zod schema you defined in the API route's file to the middleware. - -In the next step, you'll customize the UI route you added earlier to allow the admin user to approve or reject reviews. - -*** - -## Step 9: Approve and Reject Reviews in UI Route - -You'll now customize the UI route you added earlier to allow the admin user to approve or reject reviews. You'll add a checkbox column to the table that allows the admin user to select multiple reviews, then choose to approve or reject them. - -The `DataTable` component from Medusa UI supports a command bar that is triggered by a select (or checkbox) column in the table. - -Start by adding the necessary imports at the top of `src/admin/routes/reviews/page.tsx`: - -```tsx title="src/admin/routes/reviews/page.tsx" -import { - createDataTableCommandHelper, - DataTableRowSelectionState, -} from "@medusajs/ui" -``` - -Then, in the `columns` array, add a new select column as the first item in the array: - -```tsx title="src/admin/routes/reviews/page.tsx" -const columns = [ - columnHelper.select(), - // ... -] -``` - -The select column adds a checkbox to each row in the table, allowing the admin user to select multiple reviews. - -Next, you need to add the commands that allow the admin user to approve or reject the selected reviews. So, add the following after the `columns` array: - -```tsx title="src/admin/routes/reviews/page.tsx" highlights={commandHelperHighlights} -const commandHelper = createDataTableCommandHelper() - -const useCommands = (refetch: () => void) => { - return [ - commandHelper.command({ - label: "Approve", - shortcut: "A", - action: async (selection) => { - const reviewsToApproveIds = Object.keys(selection) - - sdk.client.fetch("/admin/reviews/status", { - method: "POST", - body: { - ids: reviewsToApproveIds, - status: "approved", - }, - }).then(() => { - toast.success("Reviews approved") - refetch() - }).catch(() => { - toast.error("Failed to approve reviews") - }) - }, - }), - commandHelper.command({ - label: "Reject", - shortcut: "R", - action: async (selection) => { - const reviewsToRejectIds = Object.keys(selection) - - sdk.client.fetch("/admin/reviews/status", { - method: "POST", - body: { - ids: reviewsToRejectIds, - status: "rejected", - }, - }).then(() => { - toast.success("Reviews rejected") - refetch() - }).catch(() => { - toast.error("Failed to reject reviews") - }) - }, - }), - ] -} -``` - -You first initialize the command helper using the `createDataTableCommandHelper` function from Medusa UI. Then, you create a custom hook `useCommands` that returns an array of commands created with the command helper. - -You add `Approve` and `Reject` commands, and both of them send a request to the `/admin/reviews/status` API route to update the reviews' status, but each with a different status in the request body. - -Next, add the following state variable in the `ReviewsPage` component: - -```tsx title="src/admin/routes/reviews/page.tsx" -const [rowSelection, setRowSelection] = useState({}) -``` - -This state variable will hold the selected reviews in the table. - -Then, call the `useCommands` hook and pass new properties to the `useDataTable` hook: - -```tsx title="src/admin/routes/reviews/page.tsx" -const commands = useCommands(refetch) - -const table = useDataTable({ - // ... - commands, - rowSelection: { - state: rowSelection, - onRowSelectionChange: setRowSelection, - }, -}) -``` - -You call the `useCommands` hook and pass it the `refetch` function (returned by `useQuery`). The `refetch` function allows you to refetch the reviews after approving or rejecting them to ensure their status in the table is updated. - -Then, you pass the commands and row selection configurations (from the state variables you added) to the `useDataTable` hook. - -Finally, in the `return` statement, add the command bar after the pagination component: - -```tsx title="src/admin/routes/reviews/page.tsx" - `${count} selected`} /> -``` - -This command bar will show the actions to perform on the selected reviews. - -### Test the UI Route - -To test out the UI route, start the Medusa application: - -```bash npm2yarn -npm run dev -``` - -Then, open the Medusa Admin dashboard and go to the Reviews page. You'll see a new column with checkboxes that allow you to select multiple reviews. - -If you try selecting multiple reviews, you'll see a command bar at the bottom center of the page that allows you to approve or reject the selected reviews. - -If you choose to approve or reject the reviews, the status of the selected reviews will change, and the table will update to reflect the new status. - -![Checkboxes are now shown next to the items in the table, and when you click on them the command bar shows at the bottom of the page with Approve and Reject commands](https://res.cloudinary.com/dza7lstvk/image/upload/v1741937101/Medusa%20Resources/Screenshot_2025-03-14_at_9.24.29_AM_y9vhac.png) - -*** - -## Step 10: List Reviews Store API Route - -In the upcoming steps, you'll start customizing the storefront to show the reviews of a product and allow logged-in customers to add reviews. - -Before doing that, you need to add an API route that retrieves the list of approved reviews. You'll later show these in the storefront. - -### Add Average Rating Method in Service - -On the product's page, you want to display the average rating of a product. To do this, you'll add a method that retrieves the average rating of a product's reviews in the Review Module's service. - -In `src/modules/review/service.ts`, add the following methods to the `ProductReviewModuleService` class: - -```ts title="src/modules/review/service.ts" -import { InjectManager, MedusaService, MedusaContext } from "@medusajs/framework/utils" -import Review from "./models/review" -import { Context } from "@medusajs/framework/types" -import { EntityManager } from "@mikro-orm/knex" - -class ProductReviewModuleService extends MedusaService({ - Review, -}) { - @InjectManager() - async getAverageRating( - productId: string, - @MedusaContext() sharedContext?: Context - ): Promise { - const result = await sharedContext?.manager?.execute( - `SELECT AVG(rating) as average - FROM review - WHERE product_id = '${productId}' AND status = 'approved'` - ) - - return parseFloat(parseFloat(result?.[0]?.average ?? 0).toFixed(2)) - } -} - -export default ProductReviewModuleService -``` - -To run queries on the database in a service's method, you need to: - -- Add the `InjectManager` decorator to the method. -- Pass as the last parameter a context parameter that has the `MedusaContext` decorator. - -By doing the above, Medusa injects the method with a context parameter that has a `manger` property whose value is a [forked entity manager](https://mikro-orm.io/docs/identity-map#forking-entity-manager). - -Then, you run a raw SQL query to calculate the average rating of the reviews for a product with the given ID. You also filter the reviews by the status `approved`. - -You'll use this method next in the API route. - -### Create API Route - -To create the API route that lists the reviews of a product with average rating, create the file `src/api/store/products/[id]/reviews/route.ts` with the following content: - -```ts title="src/api/store/products/[id]/reviews/route.ts" highlights={GetStoreReviewsHighlights} collapsibleLines="1-9" expandButtonLabel="Show Imports" -import { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" -import { PRODUCT_REVIEW_MODULE } from "../../../../../modules/product-review" -import ProductReviewModuleService from "../../../../../modules/product-review/service" -import { createFindParams } from "@medusajs/medusa/api/utils/validators" - -export const GetStoreReviewsSchema = createFindParams() - -export const GET = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const { id } = req.params - - const query = req.scope.resolve(ContainerRegistrationKeys.QUERY) - const reviewModuleService: ProductReviewModuleService = req.scope.resolve(PRODUCT_REVIEW_MODULE) - - // Get reviews for product - const { data: reviews, metadata: { - count, - take, - skip, - } = { count: 0, take: 10, skip: 0 } } = await query.graph({ - entity: "review", - filters: { - product_id: id, - // @ts-ignore - status: "approved", - }, - ...req.queryConfig, - }) - - res.json({ - reviews, - count, - limit: take, - offset: skip, - average_rating: await reviewModuleService.getAverageRating(id), - }) -} -``` - -You first define a `GetStoreReviewsSchema` schema that will allow clients to pass the following query parameters: - -- `limit`: The number of reviews to retrieve. -- `offset`: The number of items to skip before retrieving the reviews. -- `order`: The fields to sort the reviews by in ascending or descending order. - -Then, you export a `GET` function, and that exposes a `GET` API Route at the path `/store/products/[id]/reviews`. In the route handler you resolve [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) from the Medusa container, which allows you to retrieve data across modules. - -Next, you retrieve the approved reviews of a product using Query. Notice that you pass in `query.graph` the `req.queryConfig` object. This object holds the fields to retrieve and the pagination configurations. You'll configure this object in a bit. - -Finally, you return the reviews with pagination fields and the average rating of the product. - -### Apply Query Configurations Middleware - -The last step is to add a middleware that validates the query parameters passed to the request, and sets the default Query configuations. - -In `src/api/middlewares.ts`, add a new middleware: - -```ts title="src/api/middlewares.ts" -// other imports -import { - validateAndTransformQuery, -} from "@medusajs/framework/http" -import { GetStoreReviewsSchema } from "./store/products/[id]/reviews/route" - -export default defineMiddlewares({ - routes: [ - // ... - { - matcher: "/store/products/:id/reviews", - methods: ["GET"], - middlewares: [ - validateAndTransformQuery(GetStoreReviewsSchema, { - isList: true, - defaults: [ - "id", - "rating", - "title", - "first_name", - "last_name", - "content", - "created_at", - ], - }), - ], - }, - ], -}) -``` - -You apply the `validateAndTransformQuery` middleware to the `GET` API route at the path `/store/products/:id/reviews`. Similar to before, you pass to the middleware: - -- The validation schema of the request's query parameters, which is the `GetStoreReviewsSchema` you created earlier. -- An object of Query configurations. It has the following properties: - - `isList`: A boolean indicating whether the route returns a list of items. This enables the pagination configurations. - - `defaults`: An array of fields to retrieve by default. - -By adding this middleware, you allow clients to pass pagination query parameters to the API route, and set default fields to retrieve. - -You'll use this API route next as you customize the Next.js Starter Storefront. - -*** - -## Step 11: Customize Next.js Starter Storefront - -In this step, you'll customize the Next.js Starter Storefront to: - -- Display a product's review and average rating on its page. -- Allow authenticated customers to submit a review for a product. - -### Add Product Review Types - -Before implementing the customizations, you'll add a type definition for the product review which you'll re-use in the storefront. - -In `src/types/global.ts`, add the following types: - -```ts title="src/types/global.ts" badgeLabel="Storefront" badgeColor="blue" -export type StoreProductReview = { - id: string - title: string - rating: number - content: string - first_name: string - last_name: string -} -``` - -You define the type of a product review object and the properties it has. - -### Add Functions to Fetch and Submit Reviews - -Next, you'll add two functions that fetch and submit reviews using the API routes you created earlier. To send requests to the API routes, you can use Medusa's [JS SDK](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/js-sdk/index.html.md). - -In `src/lib/data/products.ts`, add the following functions: - -```ts title="src/lib/data/products.ts" badgeLabel="Storefront" badgeColor="blue" -import { StoreProductReview } from "../../types/global" - -// ... - -export const getProductReviews = async ({ - productId, - limit = 10, - offset = 0, -}: { - productId: string - limit?: number - offset?: number -}) => { - const headers = { - ...(await getAuthHeaders()), - } - - const next = { - ...(await getCacheOptions(`product-reviews-${productId}`)), - } - - return sdk.client.fetch<{ - reviews: StoreProductReview[] - average_rating: number - limit: number - offset: number - count: number - }>(`/store/products/${productId}/reviews`, { - headers, - query: { - limit, - offset, - order: "-created_at", - }, - next, - cache: "force-cache", - }) -} - -export const addProductReview = async (input: { - title?: string - content: string - first_name: string - last_name: string - rating: number, - product_id: string -}) => { - const headers = { - ...(await getAuthHeaders()), - } - - return sdk.client.fetch(`/store/reviews`, { - method: "POST", - headers, - body: input, - next: { - ...(await getCacheOptions(`product-reviews-${input.product_id}`)), - }, - cache: "no-store", - }) -} -``` - -You define two functions: - -- `getProductReviews`: Fetches the reviews of a product with the given ID. It accepts an object with the product ID, and optional limit and offset parameters, allowing you to paginate the reviews. -- `addProductReview`: Submits a review for a product. It accepts an object with the review's details. - -To send requests to your custom API routes, you use the JS SDK's `client.fetch` method. - -### Add Product Review Form - -You'll now create a component that shows the product review form for authenticated customers. Afterwards, you'll display this component on the product's page. - -To create the form component, create the file `src/modules/products/components/product-reviews/form.tsx` with the following content: - -```tsx title="src/modules/products/components/product-reviews/form.tsx" badgeLabel="Storefront" badgeColor="blue" -"use client" - -import { useState } from "react" - -import { useEffect } from "react" -import { retrieveCustomer } from "../../../../lib/data/customer" -import { HttpTypes } from "@medusajs/types" -import { Button, Input, Label, Textarea, toast, Toaster } from "@medusajs/ui" -import { Star, StarSolid } from "@medusajs/icons" -import { addProductReview } from "../../../../lib/data/products" - -type ProductReviewsFormProps = { - productId: string -} - -export default function ProductReviewsForm({ productId }: ProductReviewsFormProps) { - const [customer, setCustomer] = useState(null) - const [isLoading, setIsLoading] = useState(false) - const [showForm, setShowForm] = useState(false) - const [title, setTitle] = useState("") - const [content, setContent] = useState("") - const [rating, setRating] = useState(0) - - useEffect(() => { - if (customer) { - return - } - - retrieveCustomer().then(setCustomer) - }, []) - - if (!customer) { - return <> - } - - const handleSubmit = async (e: React.FormEvent) => { - if (!content || !rating) { - toast.error("Error", { - description: "Please fill in required fields.", - }) - return - } - - e.preventDefault() - setIsLoading(true) - addProductReview({ - title, - content, - rating, - first_name: customer.first_name || "", - last_name: customer.last_name || "", - product_id: productId, - }).then(() => { - setShowForm(false) - setTitle("") - setContent("") - setRating(0) - toast.success("Success", { - description: "Your review has been submitted and is awaiting approval.", - }) - }).catch(() => { - toast.error("Error", { - description: "An error occurred while submitting your review. Please try again later.", - }) - }).finally(() => { - setIsLoading(false) - }) - } - - // TODO render form -} -``` - -You create a `ProductReviewsForm` component that accepts the product's ID as a prop. In the component, you: - -- Fetch the authenticated customer's details. If the customer is not authenticated, you return an empty fragment. -- Implement a `handleSubmit` function that submits the review when the form is submitted. - -Next, you'll add a return statement that shows the form when the customer is authenticated. Replace the `TODO` with the following: - -```tsx title="src/modules/products/components/product-reviews/form.tsx" badgeLabel="Storefront" badgeColor="blue" -return ( -
- {!showForm && ( -
- -
- )} - {showForm && ( -
-
- - Add a review - - -
-
- - setTitle(e.target.value)} placeholder="Title" /> -
