qiankun结构：

主应用base：vue3+history+vite
子应用sub-react：react+history+webpack
子应用sub-vue：vue3+history+vite
子应用sub-vue2：vue2+base+webpack

❀ 主应用base

1、安装qiankun

yarn add qiankun # 或者 npm i qiankun -S

2、存放子应用信息

/src/utils/qiankun-config.js

export default {subApps: [{name: 'sub-react', // 子应用名称，跟package.json一致entry: process.env.NODE_ENV === 'development'? '//localhost:3101': '//react.qk.com', // 子应用入口，本地环境下指定端口container: '#sub-app', // 挂载子应用的domactiveRule: '/sub-react', // 路由匹配规则props: {} // 主应用与子应用通信传值},{name: 'sub-vue',entry: process.env.NODE_ENV === 'development'? '//localhost:3100': '//vue3.qk.com',container: '#sub-app',activeRule: '/sub-vue',props: {}},{name: 'sub-vue2',entry: process.env.NODE_ENV === 'development'? '//localhost:3103': '//vue2.qk.com',container: '#sub-app',activeRule: '/sub-vue2',props: {}}]}

3、开启qiankun

/src/utils/qiankun

import { registerMicroApps, initGlobalState } from 'qiankun'
import config from './qiankun-config'const { subApps } = configexport function registerApps() {try {registerMicroApps(subApps, {beforeLoad: [app => {console.log('before load', app)return Promise.resolve()}],beforeMount: [app => {console.log('before mount', app)return Promise.resolve()}],afterUnmount: [app => {console.log('before unmount', app)return Promise.resolve()}]})const actions = initGlobalState(state);// 主项目项目监听和修改actions.onGlobalStateChange((state, prev) => {// state: 变更后的状态; prev 变更前的状态console.log('主项目项目监听变化:',state, prev);});actions.setGlobalState(state);} catch (err) {console.log('qiankunError',err)}
}

4、新建一个组件，用于加载子应用

/src/page/container.vue

<template><div id="sub-app"></div>
</template><script lang="ts">
import { start } from 'qiankun'
import { registerApps } from '@/utils/qiankun'export default {mounted() {if (!window.__POWERED_BY_QIANKUN__) {window.qiankunStarted = trueregisterApps();start({sandbox: {experimentalStyleIsolation: true // 样式隔离}})}else{window.__POWERED_BY_QIANKUN__.on('mount', loadMicroApps);  如果一个页面同时展示多个微应用，需要使用 loadMicroApp 来加载。}}}
</script>

5、配置路由

export const router = createRouter({history: createWebHistory(),routes: [{path: '/',redirect: '/home',meta: {show: false}},{path: '/home',name: 'home',meta: {cnName: '首页',show: true},component: () => import('@/page/home.vue')},{path: '/about',name: 'about',meta: {cnName: '关于',show: true,keepAlive: true},component: () => import('@/page/about.vue')},{path: '/news/:id/:title/:content',name: 'news',meta: {cnName: '新闻',show: true},component: () => import('@/page/news.vue')},{path: '/communication',name: 'communication',meta: {cnName: '练习',show: true},component: () => import('@/page/communication.vue')},{// history模式需要通配所有路由，详见vue-router文档path: '/sub-react/:pathMatch(.*)*',name: 'sub-react',meta: {path:'/sub-react', // 注意：meta里的这个path是用来供router-link使用的，不用上面的path是因为点击主应用菜单跳转到子应用的时候默认带上了通配符cnName: 'sub-react',show: true,key: 'sub-react',},component: () => import('@/page/container.vue'),},{// history模式需要通配所有路由，详见vue-router文档path: '/sub-vue/:pathMatch(.*)*',name: 'sub-vue',meta: {path:'/sub-vue',cnName: 'sub-vue',show: true,key: 'sub-vue',},component: () => import('@/page/container.vue'),},{path: '/sub-vue2',name: 'sub-vue2',meta: {path:'/sub-vue2/', // 如果不加上最后的“/”，则域名会变成：http://localhost:8080/sub-vue2#/logincnName: 'sub-vue2',show: true,key: 'sub-vue2',},component: () => import('@/page/container.vue'),}]
})

*注意：meta里的这个path是用来供router-link使用的，不用上面的path是因为点击主应用菜单跳转到子应用的时候默认带上了通配符

6、首页 src/App.vue 放置 router-view

<template><header><router-linkv-for="item in routes":key="item.path":to="item.meta.path ? item.meta.path : item.path"><span>{{ item.meta?.cnName }}</span></router-link><router-view v-slot="{Component}" v-show="!$route.meta.key"><keep-alive><component :is="Component" v-if="$route.meta.keepAlive" /></keep-alive><component :is="Component" v-if="!$route.meta.keepAlive" /></router-view></header>
</template>

❀ vite子应用配置（sub-vue）

一、安装vite-plugin-qiankun（vue项目才需要安装）

npm i vite-plugin-qiankun --save-dev

二、修改vite.config.js

sub-vue 修改vite.config.js

export default defineConfig({// base: '/sub-vue',plugins: [vue(),vueJsx(),qiankun('sub-vue', {   // 配置qiankun插件useDevMode: true}),],server: {host: 'localhost',port: 3100,origin: 'http://localhost:3100/',headers: {'Access-Control-Allow-Origin': '*'}}
})

❀ webpack子应用配置（sub-react、sub-vue2）

一、修改webpack配置文件

sub-react

// 在根目录下新增config-overrides.js文件并新增如下配置
const { name } = require("./package");module.exports = {webpack: (config) => {config.output.library = `sub-react`;config.output.libraryTarget = "umd";config.output.chunkLoadingGlobal = `webpackJsonp_${name}`;return config;},devServer: (_) => {const config = _;// config.publicPath = "http://loaclhost:3101";config.headers = {'Access-Control-Allow-Origin': '*',};return config;},
};

sub-vue2

const { name } = require('./package.json')
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({transpileDependencies: true,configureWebpack: {output: {library: `sub-vue2`,libraryTarget: 'umd', // 把微应用打包成 umd 库格式// jsonpFunction: `webpackJsonp_${name}`,  // webpack5没有jsonpFunction这个optionschunkLoadingGlobal: `webpackJsonp_${name}`},},devServer:{host: 'localhost',port: 3103,headers: {'Access-Control-Allow-Origin': '*',}}
})

二、配置public-path（解决子应用图片默认取主应用的路径）

sub-react、sub-vue2 src文件下添加public-path.js

if (window.__POWERED_BY_QIANKUN__) {// eslint-disable-next-line no-undef__webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__
}

并在入口文件的第一行！！！引入它
sub-react——src——index.js

sub-vue2——src——main.js

❀ history路由入口规则（sub-vue、sub-react）

sub-vue

import { createRouter, createWebHistory } from 'vue-router'
import { qiankunWindow } from 'vite-plugin-qiankun/dist/helper'const routes = [{path: '/',redirect: { name: 'List' },meta: { title: '首页' },children: [{path: '/list',name: 'List',component: () => import('../views/List.vue')},{path: '/detail',name: 'Detail',component: () => import('../views/Detail.vue')}]},
]const router = createRouter({history: createWebHistory(qiankunWindow.__POWERED_BY_QIANKUN__ ? '/sub-vue/' : '/'),routes
})export default router

sub-react好像不需要配置，直接在App.js添加router和link

<div className='menu'><Link to={'/'}>list</Link><Link to={'/detail'}>detail</Link><a onClick={goVue}>vue列表页</a>
</div>
<Routes><Route path='/' element={<List />} /><Route path='/detail' element={<Detail />} />
</Routes>

❀ 配置生命周期（所有子组件）

sub-react——src——index.js

import './public-path.js'   // public-path处理子应用里的图片地址默认取主应用的路径
import React from 'react';
import { createRoot } from 'react-dom/client';
import './index.css';import App from './App';
import { BrowserRouter } from 'react-router-dom'
import reportWebVitals from './reportWebVitals';let root;
// 将render方法用函数包裹，供后续主应用与独立运行调用
function render(props) {const { container } = propsconst dom = container ? container.querySelector('#root') : document.getElementById('root')root = createRoot(dom)if(!container){root.render(<BrowserRouter><App/></BrowserRouter>)return}root.render(<BrowserRouter basename='/sub-react'>   // 设置路由base<App/></BrowserRouter>)
}// 判断是否在qiankun环境下，非qiankun环境下独立运行
if (!window.__POWERED_BY_QIANKUN__) {render({});
}// 各个生命周期
// bootstrap 只会在微应用初始化的时候调用一次，下次微应用重新进入时会直接调用 mount 钩子，不会再重复触发 bootstrap。
export async function bootstrap() {console.log('react app bootstraped');
}// 应用每次进入都会调用 mount 方法，通常我们在这里触发应用的渲染方法
export async function mount(props) {render(props);
}// 应用每次 切出/卸载 会调用的方法，通常在这里我们会卸载微应用的应用实例
export async function unmount(props) {root.unmount();
}// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals
reportWebVitals();

sub-vue——src——main.js

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import {renderWithQiankun,qiankunWindow
} from 'vite-plugin-qiankun/dist/helper'let app:anyconst render = (container) => {app = createApp(App)app.use(router).mount(container ? container.querySelector('#app') : '#app')
}const initQianKun = () => {renderWithQiankun({mount(props) {const { container } = propsrender(container)},bootstrap() {},unmount() {app.unmount()}})
}qiankunWindow.__POWERED_BY_QIANKUN__ ? initQianKun() : render()

sub-vue2——src——main.js

import './public-path'
import Vue from 'vue'
import App from './App.vue'
import router from './router';Vue.config.productionTip = falselet instance = nullfunction render(props = {}) {const { container } = propsinstance = new Vue({router,render: h => h(App)}).$mount(container ? container.querySelector('#app') : '#app')
}if (!window.__POWERED_BY_QIANKUN__) {render();
}export async function bootstrap() {console.log(' vue2 app bootstraped')
}
export async function mount(props) {console.log(' props from main framework', props);render(props)
}
export async function unmount() {instance.$destroy()instance.$el.innerHTML = ''instance = null
}

❀ 踩坑点：

子应用切换时出现以下警告：（我没遇到）

主应用增加：

router.beforeEach((to, from, next) => {if (!window.history.state.current) window.history.state.current = to.fullPathif (!window.history.state.back) window.history.state.back = from.fullPath// 手动修改history的statereturn next()
})
