# Vite 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.

:::warning Unsupported Options
Except for the [dev、dts](../../configure/dev.html) options, all options are supported
:::
- roadmap 🗓️
  - 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/vite --save',
    yarn: 'yarn add @module-federation/vite --save',
    pnpm: 'pnpm add @module-federation/vite --save',
    bun: 'bun add @module-federation/vite --save',
  }}
/>

### Register the Plugin

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

```ts title='vite.config.js'
import { federation } from '@module-federation/vite';
module.exports = {
  server: {
    origin: 'http://localhost:2000',
    port: 2000,
  },
  base: "http://localhost:2000",
  plugins: [
    federation({
      name: 'vite_provider',
      manifest: true,
      remotes: {
        esm_remote: {
          type: "module",
          name: "esm_remote",
          entry: "https://[...]/remoteEntry.js",
        },
        var_remote: "var_remote@https://[...]/remoteEntry.js",
      },
      exposes: {
        './button': './src/components/button',
      },
      shared: {
        react: {
          singleton: true,
        },
        'react/': {
          singleton: true,
        },
      },
    }),
  ],
  // Do you need to support build targets lower than chrome89?
  // You can use 'vite-plugin-top-level-await' plugin for that.
  build: {
    target: 'chrome89',
  },
};
```

## Configure the Build Plugin

- Type: `ModuleFederationPlugin(options: ModuleFederationOptions)`

```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.
