In this chapter, you'll learn about Medusa's commerce modules.
|
||
|
||
## What is a Commerce Module?
|
||
|
||
Medusa provides all its commerce features as separate modules, such as the Product or Order modules.
|
||
|
||
These modules and your custom modules are interchangeable in the Medusa application, making Medusa’s architecture more flexible.
|
||
|
||
Refer to [this reference](!resources!/commerce-modules) for a full list of commerce modules in Medusa.
|
||
|
||

|
||
|
||
## Resolve Commerce Module Services
|
||
|
||
Similarly to your custom module, a commerce module's main service is registered in the Medusa container. So, you can resolve it in your resources, such as API routes, to use its functionality.
|
||
|
||
For example, you saw this code snippet in the [Medusa container chapter](../medusa-container/page.mdx):
|
||
|
||
```ts highlights={[["10"]]}
|
||
import type { MedusaRequest, MedusaResponse } from "@medusajs/medusa"
|
||
import { IProductModuleService } from "@medusajs/types"
|
||
import { ModuleRegistrationName } from "@medusajs/utils"
|
||
|
||
export const GET = async (
|
||
req: MedusaRequest,
|
||
res: MedusaResponse
|
||
) => {
|
||
const productModuleService: IProductModuleService = req.scope.resolve(
|
||
ModuleRegistrationName.PRODUCT
|
||
)
|
||
|
||
const [, count] = await productModuleService
|
||
.listAndCountProducts()
|
||
|
||
res.json({
|
||
count,
|
||
})
|
||
}
|
||
```
|
||
|
||
When you resolve the `ModuleRegistrationName.PRODUCT` (or `productModuleService`) registration name, you're actually resolving the main service of the Product Module.
|
||
|
||
<Note title="Tip">
|
||
|
||
To resolve the main service of any commerce module, use the registration name defined in the `ModuleRegistrationName` enum imported from `@medusajs/modules-sdk`.
