@empjs/share v3.6.0

EMP Share

pnpm add @empjs/share

01 @empjs/share/rspack - Emp Share Plugin

使用方法

import {pluginRspackEmpShare} from '@empjs/share/rspack'
import {defineConfig} from '@empjs/cli'
export default defineConfig(store => {
  return {
    plugins: [
      pluginRspackEmpShare({
        name: 'mfHost',
        shared: {
          react: {
            singleton: true,
            requiredVersion: '18',
          },
          'react-dom': {
            singleton: true,
            requiredVersion: '18',
          },
        },
        exposes: {
          './App': './src/App',
          './CountComp': './src/CountComp',
        },
      }),
    ],
  }
})

02 @empjs/share/library - Module Federation SDK 封装

• full.js 为全量函数库、主要应对直接 老项目的桥接、通过 window直接调用共享,包含:
  • MFRuntime
  • MFSDK
  • reactAdapter
  • runtime
• sdk.js 为 SDK库包含 MFRuntime 与 MFSDK,调用还是需要安装 pnpm add @empjs/share/runtime
• sdkPolyfill.js 为 sdk + core-js

03 @empjs/share/runtime - 运行时引用

项目调用

import React, {useEffect, useState, version} from 'react'
import ReactDOM from 'react-dom'
import {CountComp as CountComp16, ShowCountComp as ShowCountComp16, Card} from './CountComp'
import {reactAdapter} from '@empjs/share/adapter' // 使用 react 
import empRuntime from '@empjs/share/runtime' // runtime 加载器
const entry = process.env.mfhost as string
// 实例化远程 emp
empRuntime.init({
  shared: reactAdapter.shared,
  remotes: [
    {
      name: 'mfHost',
      entry,
    },
  ],
  name: 'federationRuntimeDemo',
})
// 封装 React 18的组件 以便插入到 React 16
const MfApp = reactAdapter.adapter(empRuntime.load('mfHost/App'))
const CountComp = reactAdapter.adapter(empRuntime.load('mfHost/CountComp'), 'CountComp')

// 创建 React 16 组件
const ParentComponent = () => {
  return (
    <Card title={() => <>App Inject mfHost</>}>
      <CountComp name="a" />
      <CountComp16 />
    </Card>
  )
}
// 封装 React 16的组件 以便插入到 React 18
const ParentComponentAdepter = reactAdapter.adapter(ParentComponent, 'default', React, ReactDOM)
const App = () => {
  return (
    <>
      <h1>App React Version {version}</h1>
      <ShowCountComp16 />
      <Card title="EMP From mfhost">
        <MfApp component={ParentComponentAdepter} />
      </Card>
    </>
  )
}
export default App
