Install Pricing Module in Medusa

In this document, you'll learn how to install the Pricing Module using NPM in the Medusa backend.

Step 1: Install Module

To install the Pricing Module, run the following command in the root directory of the Medusa backend:

• npm
• Yarn
• pnpm

npm install @medusajs/pricing

yarn add @medusajs/pricing

pnpm add @medusajs/pricing

---

Step 2: Add Module to Configurations

In medusa-config.js, add the Pricing Module to the exported object under the modules property:

medusa-config.js

module.exports = {
  // ...
  featureFlags: {
    // ...
    medusa_v2: true,
  },
  modules: {
    // ...
    pricingService: {
      resolve: "@medusajs/pricing",
    },
  },
}

Step 3: Run Migrations

Run the following commands to reflect schema changes into your database:

npx medusa migrations run
node node_modules/@medusajs/medusa/dist/scripts/migrate-to-pricing-module.js

---

Use the Module

You can now start using the module's PricingModuleService by resolving it through dependency injection.

For example:

• API Route
• Subscribers
• Service

import type { 
  MedusaRequest, 
  MedusaResponse
} from "@medusajs/medusa";
import { 
  PricingModuleService
} from "@medusajs/pricing"

export async function GET(
  req: MedusaRequest, 
  res: MedusaResponse
) {
  const pricingModuleService: PricingModuleService = 
    req.scope.resolve(
      "pricingModuleService"
    )

  return res.json({
    pricings: pricingModuleService.list()
  })
}

import { 
  type SubscriberConfig, 
  type SubscriberArgs,
  PricingService,
} from "@medusajs/medusa"
import { 
  PricingModuleService
} from "@medusajs/pricing"

export default async function handleListPriceSets({ 
  data, eventName, container, pluginOptions 
}: SubscriberArgs<Customer>) {
  const pricingModuleService: PricingModuleService = 
    container.resolve(
      "pricingModuleService"
    )

  console.log(await pricingModuleService.list())
}

export const config: SubscriberConfig = {
  event: PricingService.Events.CREATED,
  context: {
    subscriberId: "list-pricings"
  }
}

import { TransactionBaseService } from "@medusajs/medusa"
import { 
  PricingModuleService
} from "@medusajs/pricing"

class HelloService extends TransactionBaseService {
  private pricingModuleService: PricingModuleService

  constructor(container) {
    super(container)
    this.pricingModuleService = container.pricingModuleService
  }

  await listPriceSets() {
    return await this.pricingModuleService.list()
  }
}

export default HelloService
