Rsbuild Plugin

Help users quickly build Module Federation products in Rsbuild App or Rslib

Quick Start

Installation

You can install the plugin using the following command:

npm
yarn
pnpm
bun
npm add @module-federation/rsbuild-plugin --save-dev

Register plugin

Rsbuild App

rsbuild.config.ts
import { pluginModuleFederation } from '@module-federation/rsbuild-plugin'; import { defineConfig } from '@rsbuild/core'; import { pluginReact } from '@rsbuild/plugin-react';  export default defineConfig({  server: {  port: 2000,  },  plugins: [  pluginReact(),  pluginModuleFederation({  name: 'federation_consumer',  remotes: {  remote1: 'remote1@http://localhost:2001/mf-manifest.json',  },  shared: ['react', 'react-dom'],  }),  ], });

Rslib Module

rslib.config.ts
import { pluginModuleFederation } from '@module-federation/rsbuild-plugin'; import { defineConfig } from '@rslib/core';  export default defineConfig({  lib: [  // ...  {  format: 'mf',  output: {  distPath: {  root: './dist/mf',  },  assetPrefix: 'xxx',  },  plugins: [  // ...  pluginModuleFederation({  name: 'rslib_provider',  exposes: {  '.': './src/index.tsx',  },  shared: {  react: {  singleton: true,  },  'react-dom': {  singleton: true,  },  },  }),  ],  },  ], });

Note

If you need to use the Module Federation runtime capabilities, please install @module-federation/enhanced

Configuration

  • Type:
export declare const pluginModuleFederation: (moduleFederationOptions: ModuleFederationOptions, rsbuildOptions?: RSBUILD_PLUGIN_OPTIONS) => RsbuildPlugin;  type RSBUILD_PLUGIN_OPTIONS = {  ssr?: boolean; }

moduleFederationOptions

Additional configuration for the Rsbuild plugin.

ssr

TIP

Only supports Rslib global plugins.

  • Type: boolean
  • Default: false

Enables the generation of SSR artifacts.

Example:

First, create an Rslib project using npm create module-federation@next:

# Here, three parameters (template, role, name) are passed. You can also run npm create module-federation@latest directly and follow the prompts. npm create module-federation@next -- --template provider-rslib --role provider --name rslib_ssr_provider

Then, modify the rslib.config.ts configuration to add ssr:true:

rslib.config.ts
- plugins: [pluginReact(), pluginModuleFederation(moduleFederationConfig)], + plugins: [pluginReact(), pluginModuleFederation(moduleFederationConfig, { ssr: true })],

Install dependencies and start the project:

pnpm install pnpm run mf-dev

This will generate a dist/mf/ssr directory containing the SSR artifacts.

Then, refer to the Create a Modern.js Consumer section to create a consumer, reference the Rslib SSR provider, and then start project development.
