# subscriber-config-export-required - ESLint plugin rules

This rule requires subscriber files to export a `config` object with at least an `event` property.

## Severity

`error`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets files in your project's `src/subscribers` directory. It reports a subscriber file that's missing the named `config` export, or whose `config` object doesn't declare an `event` property.

The following code is reported by the rule:

```ts title="src/subscribers/order-placed.ts"
export default async function () {}
```

Instead, export a `config` object with an `event` property:

```ts title="src/subscribers/order-placed.ts"
export default async function () {}

export const config = {
  event: "order.placed",
}
```

## Why it's Important

The `config` export tells Medusa which event(s) the subscriber listens to. Without an `event` property, Medusa can't register the subscriber for any event.

Learn more in the [Subscribers documentation](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers).

## Fixable

This rule isn't auto-fixable.
