微前端之qiankun的使用

微前端之qiankun的使用

在之前的文章中谈到了single-spa的使用，为了多了解微前端的各类架构，在新的项目中使用了qiankun，接下来就说一说qiankun的使用

安装

1、使用vue cli 快速创建基座（vue-portal）和子应用1（vue-supervise）、子应用2（vue-threen）
2、基座应用 npm install qiankun --save

准备工作做好后，我们开始分别对基座和子项目进行配置

基座应用（vue-portal）的配置

1、main.js 同级创建micro-app.js

import store from './store'
import store1 from './vuex'
const microApps = [{name: 'vthreen',// entry: `http:XXXXXXX/vthreen/`, //测试环境地址entry: '//localhost:8500/vthreen/', //本地运行地址activeRule: '/vthreen',container: '#yourContainer',},{name: 'vsupervise',// entry: `http:XXXXXXX/vsupervise/`, //测试环境地址entry: 'http://localhost:8999/vsupervise/', //本地运行地址activeRule: '/vsupervise',container: '#yourContainer',},
]const apps = microApps.map(item => {return {...item,container: '#yourContainer', // 子应用挂载的divprops: {routerBase: item.activeRule, // 下发基础路由getGlobalState: store.getGlobalState, // 下发getGlobalState方法(主应用的一些信息)store1: store1.router || []}}
})
export default apps

2、main.js中使用

import Vue from 'vue'
import App from './App.vue'
import './assets/css/main.scss'
import {  registerMicroApps, start } from 'qiankun'
import ElementUI from 'element-ui'
import './router/engine'
import './utils/directive.js'
import * as components from './components'
import '@/assets/iconfont/iconfont.css' // fontclass使用
import '@/assets/iconfont/iconfont.js' //svg方式使用
import {  encrypt, decrypt } from '@/utils/encryp.js';import store from './vuex'
import Vuex from 'vuex'
import router from './router'
Vue.config.productionTip = false
Vue.prototype.encrypt = encrypt
Vue.prototype.decrypt = decryptVue.use(ElementUI)Vue.use(Vuex)
import api from './api'
Vue.prototype.$api = apiObject.keys(components).forEach(key => {const component = components[key]if (['Col', 'Form', 'Input'].includes(key)) {Vue.component(`I${key}`, component)} else {Vue.component(key, component)}if (['Modal', 'Message', 'Notice'].includes(key)) {Vue.prototype[`$${key}`] = component}
})const instance = new Vue({router,store,render: h => h(App)
}).$mount('#app')import microApps from './micro-app'
// 定义loader方法，loading改变时，将变量赋值给App.vue的data中的isLoading
function loader(loading) {if (instance && instance.$children) {// instance.$children[0] 是App.vue，此时直接改动App.vue的isLoadinginstance.$children[0].isLoading = loading}
}// 给子应用配置加上loader方法
const apps = microApps.map(item => {return {...item,loader}
})registerMicroApps(apps, {beforeLoad: app => {},beforeMount: [app => {}],afterMount: [app => {}],afterUnmount: [app => {}]
})
start()

3、 页面挂载设置

在那个页面挂载就在该页面的mounted

<template><div id="app"><el-container class="layout" v-if="!$route.meta.showAll"><el-header><common-header :config="config"></common-header><ul class="header-nav"><li class="menu-btn pointer" @click="goPortal"><i class="el-icon-arrow-left"></i>返回首页</li><li v-for="(sys, key) in sysList" class="pointer" :class="{'active': activeId == sys.appId}":key="key" @click="toggleSys(sys)">{{sys.appName}}</li></ul></el-header><router-view v-if="$route.meta.isSingle"></router-view><!-- yourContainer 挂载容器 --><div id="yourContainer" v-else></div> </el-container><router-view v-else></router-view></div>
</template><script>
import { mapGetters } from "vuex";
import { CommonHeader } from "vue-common";
import { start } from "qiankun";
import parser from 'vue-common/dist/router/parser'
import asyncRouter from '@/router/map/async.js'
export default {name: 'App',components: {CommonHeader,},data() {return {modulesMenu: [],sysList: [],config: this.$config,breadcrumbShow: false,activeId: ""};},computed: {...mapGetters({getSysList: 'getSysList',}),},watch: {getSysList(val) {this.sysList = val},// 切换路由时监听导航渲染'$route.path'(val) {this.updateActiveRouter()}},// 页面刷新时如果不是首页要加载侧边栏mounted() {if (!window.qiankunStarted) {window.qiankunStarted = true;start(); // 启动}},methods: {goPortal() {this.$router.push({ name: 'home' })}},created() {// this.getConfigJson()}
};
</script>

4、vue.config.js设置

module.exports = {transpileDependencies: ['common'],assetsDir: 'static',lintOnSave: false, // 是否使用eslintproductionSourceMap: false, // 关闭生产源映射加速生产构建devServer: {port: 9999, // 在.env中VUE_APP_PORT=7788，与父应用的配置一致headers: {'Access-Control-Allow-Origin': '*' // 主应用获取子应用时跨域响应头},proxy: {'/api': {target: 'http://192.162.130.141:9001',// target: 'http://172.160.1.4:9001',changeOrigin: true, //开启代理pathRewrite: {'^/api': ''}},},https: false, // 不支持https协议open: true, // 配置自动启动浏览器},chainWebpack: config => {const oneOfsMap = config.module.rule('scss').oneOfs.storeoneOfsMap.forEach(item => {item.use('sass-resources-loader').loader('sass-resources-loader').options({// 全局变量文件路径，只有一个时可将数组省去resources: ['./src/assets/css/main.scss']}).end()})config.plugin('html').tap((args) => {args[0].title = 'qiankun-example'return args})}
}

5、路由设置

基座应用也是history模式，但是base不需要设置

子应用的配置

1、vue.config.js同级创建一个.env文件，端口号要与基座micro-app.js中的配置一致

2、main.js同级创建public-path.js

(function () {if (window.__POWERED_BY_QIANKUN__) {if (process.env.NODE_ENV === 'development') {// eslint-disable-next-line__webpack_public_path__ = `//localhost:${process.env.VUE_APP_PORT}${process.env.BASE_URL}`return}// eslint-disable-next-line__webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__// __webpack_public_path__ = `${process.env.BASE_URL}/`}
})()

3、main.js配置

import './public-path'
let instance = nullfunction render(props = {}) {const {container,routerBase} = props// const router = new VueRouter({//   base: window.__POWERED_BY_QIANKUN__ ? routerBase : process.env.BASE_URL,//   mode: 'history',//   routes// })//路由配置instance = new Vue({router,store,render: (h) => h(App)}).$mount(container ? container.querySelector('#vcatalog') : '#vcatalog')
}
if (!window.__POWERED_BY_QIANKUN__) {// 这里是子应用独立运行的环境，实现子应用的登录逻辑// 独立运行时，也注册一个名为global的store module// commonStore.globalRegister(store)// 模拟登录后，存储用户信息到global modulerender()
}export async function bootstrap() {}export async function mount(props) {render(props)
}export async function unmount() {instance.$destroy()instance.$el.innerHTML = ''instance = null
}

4、路由配置放在router index.js中了

所有子项目必须是history模式，base设置与基座micro-app.js中的配置一致
