目录一、cli3构建Vue2项目二、qiankun改造主应用三、qiankun改造子应用一、cli3构建vue2项目 1、前期工作：查看cli安装情况与安装 npm install

一、cli3构建vue2项目

1、前期工作：查看cli安装情况与安装

npm install -g @vue/cli

已安装情况查看：vue -V(大写的V)

2、新建项目

vue create main-project

3、选择自定义配置

配置选择

选择vue版本、babel、router、vuex、CSS预处理器、lint格式校验

选择vue 2.x

qiankun 子应用建议使用 history路由模式

选择自己喜欢的css预处理器

选择eslint标准配置

提交保存eslint都需要验证

单独的配置文件

不保存这个配置

项目创建成功

自己喜欢的eslint配置eslintrc.js

module.exports = {
    root: true,
    env: {
            node: true
    },
    extends: [
        'plugin:vue/essential',
        '@vue/standard'
    ],
    parserOptions: {
        parser: 'babel-eslint'
    },
    rules: {
        'semi': 'off',
        'quotes': 'off',
        'indent': ["error", 4],
        "space-before-function-paren": "off",
        'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
        'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off'
    }
}

4、进入项目文件夹内 cd frame安装插件

安装依赖的插件 element ui、 axiOS

安装element ui:

npm i element-ui -S

安装完成后修改main.js

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App.vue'
import router from './router'
import store from './store'
 
Vue.use(ElementUI)
 
Vue.config.productionTip = false
 
new Vue({
  router,
  store,
  render: h => h(App)
}).$mount('#app')

安装axios:

npm install axios

新建了个文件夹api index.js 引用axios，统一处理api与使用qiankun与此无关

import Axios from 'axios'

到此只是建项目，两个项目一个main-project 和sub-project

主应用 main-project：

子应用 sub-project：

二、qiankun改造主应用

1、主应用安装qiankun

npm install qiankun --save

2、给菜单增加一个router-link，to值为"/subProject"，并且在router-view的下面增加一个id为VueContainer的盒子，用于承载子应用。

3、新增一个qiankun文件夹里面加个index.js。导入qiankun中的reGISterMicroApps和star两个方法，注册子应用并启动qiankun

import { registerMicroApps, start } from "qiankun";
 
export const useQiankun = () => {
    const apps = [
        {
            name: "sub-project",
            entry: "Http://localhost:8091", // 主应用端口用8090，子应用8091
            container: "#VueContainer",
            activeRule: "/subProject", // 与route-link to的相同
            props: {
                msg: "这是父应用传过来的值，传递给子应用sub-project"
            }
        }
    ]
 
    registerMicroApps(apps, {
        beforeLoad: [
            (app) => {
                console.log(`${app.name}的beforeLoad`);
            }
        ],
        beforeMount: [
            (app) => {
                console.log(`${app.name}的beforeMount`);
            }
        ],
        afterMount: [
            (app) => {
                console.log(`${app.name}的afterMount`);
            }
        ],
        beforeUnmount: [
            (app) => {
                console.log(`${app.name}的beforeUnmount`);
            }
        ],
        afterUnmount: [
            (app) => {
                console.log(`${app.name}的afterUnmount`);
            }
        ]
    });
 
    start({ experimentalStyleIsolation: true, prefetch: "all" });
};

4、在main.js里导入 qiankun/index, 注册子应用并启动

import { useQiankun } from './qiankun/index'    
 
vueApp.$nextTick(() => {
    useQiankun()
})

三、qiankun改造子应用

1、主应用安装qiankun

npm install qiankun --save

2、先修改一下vue实例挂载的id，#app改为subApp便于区分

3、在src中增加一个文件夹qiankun，public-path.js，判断window.__ POWERED_BY_QIANKUN __，如果是从qiankun启动则将window. __ INJECTED_PUBLIC_PATH_BY_QIANKUN __ 的值赋值给 __ webpack_public_path __

if (window.__POWERED_BY_QIANKUN__) {
  // eslint-disable-next-line camelcase, no-undef
  __WEBpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__
}

4、router/index.js改造，创造vue实例移入main.js

5、main.js 导入VueRouter、routes、 public-path移除原来的router

import "./public-path";
import VueRouter from "vue-router";
import routes from "./router";

6、main.js中创建vue实例的代码提到render函数里，并接收一个参数，

router实例也放入render函数,修改router/index.js，process.env.BASE_URL,指定base值为：“/subProject”

判断public-path的window.__POWERED_BY_QIANKUN__如果不是从qiankun启动，直接调用render表示独立运行

let instance
let router
function render(props = {}) {
    const { container } = props;
    router = new VueRouter({
        mode: "history",
        base: "/subProject",
        routes
    });
    instance = new Vue({
        router,
        store,
        render: (h) => h(App)
    }).$mount(container ? container.querySelector("#subApp") : "#subApp");
}
// 如果不是从qiankun启动，直接调用render表示独立运行
if (!window.__POWERED_BY_QIANKUN__) {
    render();
}

5、main.js 导出3个必需的方法bootstrap，mount和unmount；mount函数中调用render方法进行子应用渲染。unmount函数中将render方法中创建的vue实例销毁。

export async function bootstrap() {
    console.log("[vue] vue bapp bootstraped");
}
export async function mount(props) {
    console.log("[vue] props from main framework", props);
    render(props);
}
export async function unmount() {
    instance.$destroy();
    instance.$el.innerhtml = "";
    instance = null;
    router = null;
}

整体的main.js

import "./qiankun/public-path";
import Vue from "vue";
import VueRouter from "vue-router";
import ElementUI from "element-ui";
import "element-ui/lib/theme-chalk/index.css";
import "./assets/main.css";
import App from "./App.vue";
import routes from "./router";
import store from "./store";
 
Vue.use(ElementUI);
 
Vue.config.productionTip = false;
 
let instance
let router
function render(props = {}) {
    const { container } = props;
    router = new VueRouter({
        mode: "history",
        base: "/subProject",
        routes
    });
    instance = new Vue({
        router,
        store,
        render: (h) => h(App)
    }).$mount(container ? container.querySelector("#subApp") : "#subApp");
}
// 如果不是从qiankun启动，直接调用render表示独立运行
if (!window.__POWERED_BY_QIANKUN__) {
    render();
}
 
export async function bootstrap() {
    console.log("[vue] vue bapp bootstraped");
}
export async function mount(props) {
    console.log("[vue] props from main framework", props);
    render(props);
}
export async function unmount() {
    instance.$destroy();
    instance.$el.innerHTML = "";
    instance = null;
    router = null;
}

5、增加vue.config.js，

配置允许跨域：“ Access-Control-Allow-Origin：’*’ ”，并配置webpack的output.library和output.libraryTarget

const { name } = require('./package');
module.exports = {
    productionSourceMap: false,
    lintOnSave: process.env.NODE_ENV === 'development',
    devServer: {
        proxy: {
            "/cmp": {
                target: "https://11.11.9.206:8080",
                ws: true,
                changeOrigin: true,
                secure: false
                // pathRewrite: { "^/cmp/api": "" }
            }
        },
        headers: {
            'Access-Control-Allow-Origin': '*'
        }
    },
    configureWebpack: {
        name: name,
        output: {
            library: `${name}-[name]`,
            libraryTarget: 'umd', // 把微应用打包成 umd 库格式
            JSONpFunction: `webpackJsonp_${name}`
        }
    }
};

6、最终样子
