vite-plugin-federation

Build Status Version Node Compatibility License

A Vite plugin which support Module Federation. Inspired by Webpack Module Federation feature.

Install

Using npm:

npm install @originjs/vite-plugin-federation --save-dev

Usage

The main steps in using federation are:

Step 1: change the configuration

  • for a Vite project, in vite.config.js:
import { defineConfig } from 'vite'
import federation from "@originjs/vite-plugin-federation";

export default defineConfig({
  plugins: [
    federation({
      name: 'module-name',
      filename: 'remoteEntry.js',
      exposes: {
        './Button': './src/Button.vue',
      },
      remotes:{
          foo: 'remote_foo'
      }
      shared: ['vue']
    })
  ],
})
  • for a Rollup project, in rollup.config.js:
import federation from '@originjs/vite-plugin-federation'


export default {
  input: 'src/index.js',
  output: {
    format: 'esm',
    dir: 'dist'
  },
  plugins: [
    federation({
      filename: 'remoteEntry.js',
      exposes: {
        './Button': './src/button'
      },
      shared: ['react']
    })
  ]
}

Step 2: asynchronous references

Vue2, for example

<script>
export default {
  name: 'App',
  components: {
    RemoteButtonScoped: () => import('remote-simple/remote-simple-button-scoped'),
  }
}
</script>

Step 3: Use Remote module components

Vue2, for example

<template>
  <div>
  		<RemoteButtonScoped />
  </div>
</template>

Configuration description

exposes

name: string

Required as the module name of the remote module.

filename:string

As the entry file of the remote module, not required, default is remoteEntry.js

As the remote module, the list of components exposed to the public, required for the remote module.

exposes: {
// 'externally exposed component name': 'externally exposed component address'
    '. /remote-simple-button': '. /src/components/Button.vue',
        '. /remote-simple-section': '. /src/components/Section.vue'
},

remotes

The remote module entry file referenced as a local module

remotes: {
  // 'remote module name': 'remote module entry file address'
  'remote-simple': 'http://localhost:5011/remoteEntry.js',
},

shared

Dependencies shared by local and remote modules. Local modules need to configure the dependencies of all used remote modules; remote modules need to configure the dependencies of externally provided components.

configuration information

import: boolean

The default is true, whether to add shared to the module, only for the remote side, remote will reduce some of the packaging time when this configuration is turned on, because there is no need to package some of the shared, but once there is no shared module available on the host side, it will report an error directly, because there is no fallback module available

shareScope: string

Default is defualt, the shared domain name, just keep the remote and host sides the same

version: string

Only works on host side, the version of the shared module provided is version of the package.json file in the shared package by default, you need to configure it manually only if you can't get version by this method

requiredVersion: string

Only for the remote side, it specifies the required version of the host shared used, when the version of the host side does not meet the requiredVersion requirement, it will use its own shared module, provided that it is not configured with import=false, which is not enabled by default

Examples

Construct

vite-plugin-federation dependencies are required during the development and build process, and global installation is recommended.

  • rollup
  • vite

Part of example requires dependencies, recommended for global installation.

  • lerna
  • rimraf

Github CI build, not engineering required:

  • playwright-chromium
