vue微前端系统的搭建

首先最少创建两个项目：一个主系统：vue-qiankun-base(vue create vue-qiankun-base)；一个子系统：vue-qiankun-app(vue create vue-qiankun-base)

一、主系统搭建

1.先安装qiankun

npm i qiankun -S
1

2.子应用项目导入
main.js

import { registerMicroApps, start } from 'qiankun';
Vue.config.productionTip = false
registerMicroApps([
  {
    name: 'qiankun-app',
    entry: '//localhost:8082/',// 运行微应用的地址
    container: '#qiankun-app',// 展示的DOM容器 id
    activeRule: '/',// 跳转路径
    props: {
      token: '',
    }// 通过props实现通信传递值
  },
]);
// // 启动 qiankun
start({ prefetch: false });

3.子系统在主系统挂载
App.vue

<template>
  <div id="app">
    <div id="qiankun-app">div>
    
  div>
template>

二、子系统搭建

1.在src下新建public-path.js文件

if (window.__POWERED_BY_QIANKUN__) {
    __webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__;
}

2.在main.js里写配置项

import Vue from 'vue'
import App from './App.vue'
import './public-path';
import VueRouter from 'vue-router';
import routes from './router';
Vue.config.productionTip = false

let router = null;
let instance = null;
function render(props = {}) {
  const { container } = props;
  router = new VueRouter({
    base: window.__POWERED_BY_QIANKUN__ ? '/child/' : '/',
    mode: 'hash',
    routes,
  });

  instance = new Vue({
    router,
    render: (h) => h(App),
  }).$mount(container ? container.querySelector('#app') : '#app');
}

// 独立运行时
if (!window.__POWERED_BY_QIANKUN__) {
  render();
}

export async function bootstrap() {
  console.log('[vue] vue app 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;
}

3.修改vue.config.js

const webpack = require('webpack')

const { name } = require('./package')
const path = require('path')
function resolve(dir) {
  return path.join(__dirname, dir)
}

const { defineConfig } = require('@vue/cli-service')
const publicPath = '/'
module.exports = defineConfig({
  transpileDependencies: true,
  publicPath,
  outputDir: 'child',
  assetsDir: 'static',
  productionSourceMap: false,
  devServer: {
    port: 8082,
    headers: {
      'Access-Control-Allow-Origin': '*',
    },
  },
  configureWebpack: {
    resolve: {
      alias: {
        '@': resolve('src'),
      },
    },
    output: {
      // 把子应用打包成 umd 库格式
      library: `${name}-[name]`,
      libraryTarget: 'umd',
    }

  },

})
