|
|
|
|
The Promotion Module is the `@medusajs/promotion` NPM package that provides promotion-related features in your Medusa and Node.js applications.
|
|
|
|
## Features
|
|
|
|
### Discount Functionalities
|
|
|
|
A promotion discounts an amount or percentage of a cart's items, shipping methods, or the entire order.
|
|
|
|
The Promotion Module allows you to store and manage promotions.
|
|
|
|
```ts
|
|
const promotion = await promotionModuleService.create({
|
|
code: "10%OFF",
|
|
type: "standard",
|
|
application_method: {
|
|
type: "percentage",
|
|
target_type: "order",
|
|
value: "10",
|
|
currency_code: "usd"
|
|
},
|
|
})
|
|
```
|
|
|
|
### Flexible Promotion Rules
|
|
|
|
A promotion has rules that restricts when it's applied. For example, you can create a promotion that's only applied to VIP customers.
|
|
|
|
```ts
|
|
const promotion = await promotionModuleService.create({
|
|
code: "10%OFF",
|
|
type: "standard",
|
|
application_method: {
|
|
type: "percentage",
|
|
target_type: "order",
|
|
value: "10",
|
|
currency_code: "usd"
|
|
},
|
|
rules: [
|
|
{
|
|
attribute: "customer_group_id",
|
|
operator: "eq",
|
|
values: ["VIP"],
|
|
},
|
|
],
|
|
})
|
|
```
|
|
|
|
### Campaign Management
|
|
|
|
A campaign combines promotions under the same conditions, such as start and end dates.
|
|
|
|
A campaign can also have an identifier for tracking purposes, such as tracking through tools like Google Analytics.
|
|
|
|
```ts
|
|
const campaign = await promotionModuleService.createCampaigns(
|
|
{
|
|
name: "Summer Discounts",
|
|
campaign_identifier: "G-123445",
|
|
starts_at: new Date("2024-05-02"),
|
|
ends_at: new Date("2024-07-20"),
|
|
}
|
|
)
|
|
```
|
|
|
|

|
|
|
|
## Configure Promotion Module
|
|
|
|
To use the Promotion Module, enable it in the `modules` object in `medusa-config.js`:
|
|
|
|
```js title="medusa-config.js"
|
|
const { Modules } = require("@medusajs/modules-sdk")
|
|
|
|
// ...
|
|
|
|
const modules = {
|
|
// ...
|
|
[Modules.PROMOTION]: true,
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## How to Use the Promotion Module's Service
|
|
|
|
You can use the Promotion Module's main service by resolving from the Medusa container the resource `ModuleRegistrationName.PROMOTION` imported from `@medusajs/modules-sdk`.
|
|
|
|
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/medusa"
|
|
import { IPromotionModuleService } from "@medusajs/types"
|
|
import { ModuleRegistrationName } from "@medusajs/modules-sdk"
|
|
|
|
export async function GET(
|
|
request: MedusaRequest,
|
|
res: MedusaResponse
|
|
): Promise<void> {
|
|
const promotionModuleService: IPromotionModuleService =
|
|
request.scope.resolve(ModuleRegistrationName.PROMOTION)
|
|
|
|
res.json({
|
|
promotions: await promotionModuleService.list(),
|
|
})
|
|
}
|
|
```
|
|
|
|
</CodeTab>
|
|
<CodeTab label="Subscriber" value="subscribers">
|
|
|
|
```ts title="src/subscribers/custom-handler.ts"
|
|
import { SubscriberArgs } from "@medusajs/medusa"
|
|
import { IPromotionModuleService } from "@medusajs/types"
|
|
import { ModuleRegistrationName } from "@medusajs/modules-sdk"
|
|
|
|
export default async function subscriberHandler({
|
|
container,
|
|
}: SubscriberArgs) {
|
|
const promotionModuleService: IPromotionModuleService =
|
|
container.resolve(ModuleRegistrationName.PROMOTION)
|
|
|
|
const promotions = await promotionModuleService.list()
|
|
}
|
|
```
|
|
|
|
</CodeTab>
|
|
<CodeTab label="Workflow Step" value="workflow-step">
|
|
|
|
```ts title="src/workflows/hello-world/step1.ts"
|
|
import { createStep } from "@medusajs/workflows-sdk"
|
|
import { IPromotionModuleService } from "@medusajs/types"
|
|
import { ModuleRegistrationName } from "@medusajs/modules-sdk"
|
|
|
|
const step1 = createStep(
|
|
"step-1",
|
|
async (_, { container }) => {
|
|
const promotionModuleService: IPromotionModuleService =
|
|
container.resolve(ModuleRegistrationName.PROMOTION)
|
|
|
|
const promotions = await promotionModuleService.list()
|
|
})
|
|
```
