|
|
|
The Cart Module is the `@medusajs/medusa/cart` NPM package that provides cart-related features in your Medusa and Node.js applications.
|
|
|
|
## How to Use Cart Module's Service
|
|
|
|
You can use the Cart Module's main service by resolving from the Medusa container the resource `Modules.CART` imported from `@medusajs/framework/utils`.
|
|
|
|
For example:
|
|
|
|
<CodeTabs groupId="resource-type">
|
|
<CodeTab label="API Route" value="api-route">
|
|
|
|
```ts title="src/api/store/custom/route.ts"
|
|
import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http"
|
|
import { ICartModuleService } from "@medusajs/framework/types"
|
|
import { Modules } from "@medusajs/framework/utils"
|
|
|
|
export async function GET(
|
|
req: MedusaRequest,
|
|
res: MedusaResponse
|
|
): Promise<void> {
|
|
const cartModuleService: ICartModuleService = req.scope.resolve(
|
|
Modules.CART
|
|
)
|
|
|
|
res.json({
|
|
carts: await cartModuleService.listCarts(),
|
|
})
|
|
}
|
|
```
|
|
|
|
</CodeTab>
|
|
<CodeTab label="Subscriber" value="subscribers">
|
|
|
|
```ts title="src/subscribers/custom-handler.ts"
|
|
import { SubscriberArgs } from "@medusajs/framework"
|
|
import { ICartModuleService } from "@medusajs/framework/types"
|
|
import { Modules } from "@medusajs/framework/utils"
|
|
|
|
export default async function subscriberHandler({ container }: SubscriberArgs) {
|
|
const cartModuleService: ICartModuleService = container.resolve(
|
|
Modules.CART
|
|
)
|
|
|
|
const carts = await cartModuleService.listCarts()
|
|
}
|
|
```
|
|
|
|
</CodeTab>
|
|
<CodeTab label="Workflow Step" value="workflow-step">
|
|
|
|
```ts title="src/workflows/hello-world/step1.ts"
|
|
import { createStep } from "@medusajs/framework/workflows-sdk"
|
|
import { ICartModuleService } from "@medusajs/framework/types"
|
|
import { Modules } from "@medusajs/framework/utils"
|
|
|
|
const step1 = createStep("step-1", async (_, { container }) => {
|
|
const cartModuleService: ICartModuleService = container.resolve(
|
|
Modules.CART
|
|
)
|
|
|
|
const carts = await cartModuleService.listCarts()
|
|
})
|
|
```
|
|
|
|
</CodeTab>
|
|
</CodeTabs>

## Features
|
|
|
|
### Cart Management
|
|
|
|
Store and manage carts, including their addresses, line items, shipping methods, and more.
|
|
|
|
```ts
|
|
const cart = await cartModuleService.createCarts({
|
|
currency_code: "usd",
|
|
shipping_address: {
|
|
address_1: "1512 Barataria Blvd",
|
|
country_code: "us",
|
|
},
|
|
items: [
|
|
{
|
|
title: "Shirt",
|
|
unit_price: 1000,
|
|
quantity: 1,
|
|
},
|
|
],
|
|
})
|
|
```
|
|
|
|
### Apply Promotions
|
|
|
|
Apply promotions or discounts to line items and shipping methods by adding adjustment lines that are factored into their subtotals.
|
|
|
|
```ts
|
|
const lineAdjustments = await cartModuleService.addLineItemAdjustments({
|
|
item_id: "cali_123",
|
|
code: "50OFF",
|
|
amount: 500,
|
|
})
|
|
|
|
const shippingAdjustments =
|
|
await cartModuleService.addShippingMethodAdjustments({
|
|
shipping_method_id: "casm_123",
|
|
code: "FREESHIPPING",
|
|
amount: 1000,
|
|
})
|
|
```
|
|
|
|
### Cart Context and Scoping
|
|
|
|
A cart is scoped to a sales channel, region, and a customer.
|
|
|
|
When used with their respective modules and other commerce modules, you benefit from features like:
|
|
|
|
- Checking product availability in a sales channel.
|
|
- Retrieving pricing per region.
|
|
- Applying promotions based on the customer's group.
