# Webpack Plugin

- Can build modules that meet the `Module Federation` loading specifications.
- Can consume modules that adhere to the `Module Federation` specifications using aliases.
- Can configure shared dependencies for modules, so that when the host environment of the loaded module already has the corresponding dependency, it will not be loaded again.
- When a module has remote types, it will automatically download and consume the types of the remote modules.
- Consuming remote modules will have hot update capabilities.

## Quick Start

### Installation

You can install the plugin with the following commands:

import { PackageManagerTabs } from '@theme';

<PackageManagerTabs
  command={{
    npm: 'npm add @module-federation/enhanced --save',
    yarn: 'yarn add @module-federation/enhanced --save',
    pnpm: 'pnpm add @module-federation/enhanced --save',
    bun: 'bun add @module-federation/enhanced --save',
  }}
/>

### Register the Plugin

In `Webpack`, you can add the plugin through the `plugins` configuration item in the `webpack.config.js` file:

:::warning Public Path Auto & Manifest
When using mf-manifest.json remotes `publicPath: 'auto'` support is experimental
:::

```ts title='webpack.config.js'
import { ModuleFederationPlugin } from '@module-federation/enhanced/webpack';
module.exports = {
  devServer: {
    port: 2000,
  },
  output: {
    publicPath: 'http://localhost:2000/', // or auto
  },
  plugins: [
    new ModuleFederationPlugin({
      name: 'webpack_provider',
      filename: 'remoteEntry.js',
      exposes: {
        // Set the modules to be exported, default export as '.'
        './button': './src/components/button',
      },
      shared: {
        react: {
          singleton: true,
        },
        'react-dom': {
          singleton: true,
        },
      },
    }),
  ],
};
```

## Configure the Build Plugin

- Type: `ModuleFederationPlugin(options: ModuleFederationOptions)`

- The configuration structure for the Module Federation plugin is as follows:

```ts
type ModuleFederationOptions = {
  name: string;
  filename?: string;
  remotes?: Array<RemoteInfo>;
  shared?: ShareInfos;
};
```

You can find detailed explanations of all configuration items on the [Configuration Overview](../../configure/index) page.
