The Region Module provides region-related features in your Medusa and Node.js applications.

## How to Use Region Module's Service

You can use the Region Module's main service by resolving from the Medusa container the resource `Modules.REGION` imported from `@medusajs/framework/utils`.

For example:

<CodeTabs groupId="resource-type">
  <CodeTab label="Workflow Step" value="workflow-step">

```ts title="src/workflows/hello-world/step1.ts"
import { createStep } from "@medusajs/framework/workflows-sdk"
import { Modules } from "@medusajs/framework/utils"

const step1 = createStep("step-1", async (_, { container }) => {
  const regionModuleService = container.resolve(
    Modules.REGION
  )

  const regions = await regionModuleService.listRegions()
})
```

  </CodeTab>
  <CodeTab label="API Route" value="api-route">

```ts title="src/api/store/custom/route.ts"
import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http"
import { Modules } from "@medusajs/framework/utils"

export async function GET(
  req: MedusaRequest,
  res: MedusaResponse
): Promise<void> {
  const regionModuleService = req.scope.resolve(
    Modules.REGION
  )

  res.json({
    regions: await regionModuleService.listRegions(),
  })
}
```

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

```ts title="src/subscribers/custom-handler.ts"
import { SubscriberArgs } from "@medusajs/framework"
import { Modules } from "@medusajs/framework/utils"

export default async function subscriberHandler({ container }: SubscriberArgs) {
  const regionModuleService = container.resolve(
    Modules.REGION
  )

  const regions = await regionModuleService.listRegions()
}
```

  </CodeTab>
</CodeTabs>

## What is a Region?

A region represents the area you sell products in. Each region can cover multiple countries, but uses a single currency.

## Features

### Region Management

You can manage your regions to create, update, retrieve, or delete them.

```ts
const region = await regionModuleService.createRegions({
  name: "Europe",
  currency_code: "eur",
})
```

### Multi-Currency Support

As each region has a currency, you can support multiple currencies in your store by creating multiple regions.

```ts
const regions = await regionModuleService.createRegions([
  {
    name: "Europe",
    currency_code: "eur",
  },
  {
    name: "United States of America",
    currency_code: "usd",
  },
])
```

### Different Settings Per Region

Each region has its own settings, such as what countries belong to a region or its tax settings. Each region has different tax rates, payment providers, and more provided by other commerce modules.

```ts
const regions = await regionModuleService.createRegions([
  {
    name: "Europe",
    currency_code: "eur",
    countries: ["dk", "de", "fr", "it", "pt"],
    automatic_taxes: true,
  },
  {
    name: "United States of America",
    currency_code: "usd",
    countries: ["us"],
    payment_providers: ["stripe"],
  },
])
```
