# Exposes
- Type: `PluginExposesOptions`
- Required: No
- Default value: `undefined`
- Usage: Determines the modules and file entries exposed by `Module Federation`.
:::tip
A producer-specific parameter, setting `exposes` indicates that this is a producer.
:::
After configuration, the exposed modules will be separated into a distinct chunk, and if there are any asynchronous chunks, they will be extracted into individual chunks as well (the specific extraction behavior depends on the chunk splitting rules).
The `PluginExposesOptions` type is as follows:
```tsx
interface PluginExposesOptions {
[exposeKey: string]: string | ExposesConfig;
}
interface ExposesConfig {
// File entry
import: string;
}
```
The `exposeKey` is essentially consistent with the [Package Entry Points](https://nodejs.org/api/packages.html#package-entry-points) specification (except for not supporting regular expression matching).
Example:
```jsx
module.exports = {
plugins: [
new ModuleFederationPlugin({
name: 'provider',
exposes: {
// Note: "./" is not supported. Exporting as `.` indicates a default export
'.': './src/index.tsx',
'./add': './src/utils/add.ts',
'./Button': './src/components/Button.tsx',
},
}),
],
};
```
