qiankun：vite/webpack项目配置

https://www.bilibili.com/video/BV12T411q7dq/?spm_id_from=333.337.search-card.all.click

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

bash 复制代码

yarn add qiankun # 或者 npm i qiankun -S

2、存放子应用信息

/src/utils/qiankun-config.js

typescript 复制代码

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dom
        activeRule: '/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

typescript 复制代码

import { registerMicroApps, initGlobalState } from 'qiankun'
import config from './qiankun-config'

const { subApps } = config

export 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

typescript 复制代码

<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 = true
        registerApps();
        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

typescript 复制代码

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#/login
        cnName: '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

typescript 复制代码

<template>
	<header>
	    <router-link
	      v-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）

typescript 复制代码

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

二、修改vite.config.js

sub-vue 修改vite.config.js

typescript 复制代码

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

javascript 复制代码

// 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

javascript 复制代码

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_${name}`,  // webpack5没有jsonpFunction这个options
      chunkLoadingGlobal: `webpackJsonp_${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

javascript 复制代码

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

typescript 复制代码

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

javascript 复制代码

<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

javascript 复制代码

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 } = props
  const 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

javascript 复制代码

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import {
  renderWithQiankun,
  qiankunWindow
} from 'vite-plugin-qiankun/dist/helper'

let app:any

const render = (container) => {
  app = createApp(App)
  app
    .use(router)
    .mount(container ? container.querySelector('#app') : '#app')
}

const initQianKun = () => {
  renderWithQiankun({
    mount(props) {
      const { container } = props
      render(container)
    },
    bootstrap() {},
    unmount() {
      app.unmount()
    }
  })
}

qiankunWindow.__POWERED_BY_QIANKUN__ ? initQianKun() : render()

sub-vue2------src------main.js

javascript 复制代码

import './public-path'
import Vue from 'vue'
import App from './App.vue'
import router from './router';

Vue.config.productionTip = false

let instance = null

function render(props = {}) {
  const { container } = props
  instance = 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：

javascript 复制代码

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