In this section of the documentation, you will find resources to learn more about the Product Module and how to use it in your application.

Refer to the Medusa Admin User Guide to learn how to manage products using the dashboard.

</Note>

Medusa has product related features available out-of-the-box through the Product Module. A module is a standalone package that provides features for a single domain. Each of Medusa's commerce features are placed in Commerce Modules, such as this Product Module.

<Note>

Product Features

Products Management: Store and manage products. Products have custom options, such as color or size, and each variant in the product sets the value for these options.
Product Organization: The Product Module provides different data models used to organize products, including categories, collections, tags, and more.
Bundled and Multi-Part Products: Create and manage inventory kits for a single product, allowing you to implement use cases like bundled or multi-part products.
Tiered Pricing and Price Rules: Set prices for product variants with tiers and rules, allowing you to create complex pricing strategies.

How to Use the Product Module

In your Medusa application, you build flows around Commerce Modules. A flow is built as a Workflow, which is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism.

You can build custom workflows and steps. You can also re-use Medusa's workflows and steps, which are provided by the @medusajs/medusa/core-flows package.

For example:

export const highlights = [ ["12", "Modules.PRODUCT", "Resolve the module in a step."] ]

import { 
  createWorkflow, 
  WorkflowResponse,
  createStep,
  StepResponse,
} from "@medusajs/framework/workflows-sdk"
import { Modules } from "@medusajs/framework/utils"

const createProductStep = createStep(
  "create-product",
  async ({}, { container }) => {
    const productService = container.resolve(Modules.PRODUCT)

    const product = await productService.createProducts({
      title: "Medusa Shirt",
      options: [
        {
          title: "Color",
          values: ["Black", "White"],
        },
      ],
      variants: [
        {
          title: "Black Shirt",
          options: {
            Color: "Black",
          },
        },
      ],
    })

    return new StepResponse({ product }, product.id)
  },
  async (productId, { container }) => {
    if (!productId) {
      return
    }
    const productService = container.resolve(Modules.PRODUCT)

    await productService.deleteProducts([productId])
  }
)

export const createProductWorkflow = createWorkflow(
  "create-product",
  () => {
    const { product } = createProductStep()

    return new WorkflowResponse({
      product,
    })
  }
)

You can then execute the workflow in your custom API routes, scheduled jobs, or subscribers:

import type {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"
import { createProductWorkflow } from "../../workflows/create-product"

export async function GET(
  req: MedusaRequest,
  res: MedusaResponse
) {
  const { result } = await createProductWorkflow(req.scope)
    .run()

  res.send(result)
}

</CodeTab> <CodeTab label="Subscriber" value="subscriber">

import {
  type SubscriberConfig,
  type SubscriberArgs,
} from "@medusajs/framework"
import { createProductWorkflow } from "../workflows/create-product"

export default async function handleUserCreated({
  event: { data },
  container,
}: SubscriberArgs<{ id: string }>) {
  const { result } = await createProductWorkflow(container)
    .run()

  console.log(result)
}

export const config: SubscriberConfig = {
  event: "user.created",
}

</CodeTab> <CodeTab label="Scheduled Job" value="scheduled-job">

import { MedusaContainer } from "@medusajs/framework/types"
import { createProductWorkflow } from "../workflows/create-product"

export default async function myCustomJob(
  container: MedusaContainer
) {
  const { result } = await createProductWorkflow(container)
    .run()

  console.log(result)
}

export const config = {
  name: "run-once-a-day",
  schedule: `0 0 * * *`,
}

</CodeTab> </CodeTabs>
