# DllPlugin

The `DllPlugin` is used in a separate rspack configuration exclusively to create a dll-only-bundle.

## Examples

```js
import { rspack } from '@rspack/core';
import path from 'node:path';

new rspack.DllPlugin({
  path: path.resolve(import.meta.dirname, 'manifest.json'),
  name: '[name]_dll_lib',
});
```

The Plugin will create a `manifest.json` which is written to the given path.
It contains mappings from require and import requests to module ids.

The `manifest.json` is used by the [DllReferencePlugin](/plugins/dll-reference-plugin.md)

Combine this plugin with `output.library` options to expose the dll function.

## Options

```ts
type DllPluginOptions = {
  context?: string;
  entryOnly?: boolean;
  format?: boolean;
  name?: string;
  path: string;
  type?: string;
};
```

### context

- **Type:** `string`
- **Default:** The Rspack compiler context

Sets the context used for requests in the manifest file.

### entryOnly

- **Type:** `boolean`
- **Default:** `true`

If `true`, only entry modules are exposed.

### format

- **Type:** `boolean`
- **Default:** `false`

Controls whether the generated manifest JSON is formatted for readability.

### name

- **Type:** `string`
- **Default:** `undefined`

Sets the name of the exposed DLL function. Configure it to match the DLL bundle's `output.library` name.

### path

- **Type:** `string`

Sets the absolute output path of the manifest JSON file. This option is required.

### type

- **Type:** `string`
- **Default:** `undefined`

Sets the external type of the DLL bundle. Configure it to match `output.library.type`.
