Vue + qiankun 快速实现前端微服务

import App from "./App.vue"

Vue.config.productionTip = false
let app = null;
/**
 * 渲染函数
 * appContent 子应用html内容
 * loading 子应用加载效果，可选
 */
function render({ appContent, loading } = {}) {
    if (!app) {
        app = new Vue({
            el: "#container",
            router,
            data() {
                return {

            render(h) {
                return h(App, {
                    props: {
                        content: this.content,
                        loading: this.loading
                    }
                });
            }
        });
    } else {

// 传入子应用的数据
let msg = {
    data: {
        auth: false
    },
    fns: [
        {
            name: "_LOGIN",
            _LOGIN(data) {
                console.log(`父应用返回信息${data}`);
            }

// 注册子应用

            name: "sub-app-1",
            entry: "//localhost:8091",
            render,
            activeRule: genActiveRule("/app1"),
            props: msg
        },
        {
            name: "sub-app-2",
            entry: "//localhost:8092",
            render,
            activeRule: genActiveRule("/app2"),
        }
    ],
    {
        beforeLoad: [
            app => {
                console.log("before load", app);
            }
        ], // 挂载前回调
        beforeMount: [
            app => {
                console.log("before mount", app);
            }
        ], // 挂载后回调
        afterUnmount: [
            app => {
                console.log("after unload", app);
            }
        ] // 卸载后回调
    }
);

// 设置默认子应用,与 genActiveRule中的参数保持一致
setDefaultMountApp("/app1");

// 启动
start();

1. 修改主应用 index.html 中绑定的 id ，需与 el  绑定 dom 为一致;
2. 调整 App.vue 文件，增加渲染子应用的盒子:

<template>
  <div id="main-root">
    <!-- loading -->
    <div v-if="loading">loading</div>
    <!-- 子应用盒子 -->
    <div id="root-view" class="app-view-box" v-html="content"></div>
  </div>
</template>

<script>
export default {
  name: "App",
  props: {
    loading: Boolean,
    content: String
  }
};
</script>

module.exports = {
devServer: {
port: 8090

    }

}

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

Vue.config.productionTip = false;

let router = null;
let instance = null;

function render() {
    router = new VueRouter({
        base: window.__POWERED_BY_QIANKUN__ ? '/app1' : '/',
        mode: 'history',
        routes,
    });

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

if (!window.__POWERED_BY_QIANKUN__) {
    render();
}

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

export async function mount(props) {
    console.log('props from main app', props);
    render();
}

export async function unmount() {
    instance.$destroy();
    instance = null;
    router = null;
}

1. 配置 vue.config.js

const path = require('path');
const { name } = require('./package');

function resolve(dir) {
    return path.join(__dirname, dir);
}

const port = 8091; // dev port

module.exports = {
  /**
   * You will need to set publicPath if you plan to deploy your site under a sub path,
   * for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/,
   * then publicPath should be set to "/bar/".
   * In most cases please use '/' !!!
