How to use vue+webpack to make asynchronous loading

This time I will show you how to use vue webpack to make asynchronous loading, and what are the precautions for using vue webpack to make asynchronous loading. The following is a practical case, let's take a look.

1. The first example

const Home = resolve => {
  import("@/components/home/home.vue").then( module => {
      resolve(module)
  }
}

Note: (You don’t need to write the suffix when importing above)

export default [{
  path: '/home',
  name:'home',
  component: Home,
  meta: {
    requireAuth: true, // 添加该属性可以判断出该页面是否需要登录显示
  },
}]

2.The second example

const router = new Router({
  routes: [
    {
       path: '/home',
       component: (resolve)=> {
         require(['../components/home/home'], resolve) // 省去了在上面去import引入
       }
     }
  ]
})

3 .The third example, this is also a recommended one

// r就是resolve// 路由也是正常的写法 这种是官方推荐的写的 按模块划分懒加载 
const Home = r => require.ensure([], () => r(require('../components/home/home')), 'home');
const router = new Router({
  routes: [
    {
     path: '/home/home',
     component: Home,
     name: 'home' ,
    }
  ]
})

Let me introduce to you the code for vue webpack to implement asynchronous component loading. The specific code is as follows:

HTML

<input type="button" @click="showchild" value="show"> //点击按钮后，show为真,先获取child组件，再渲染p内容 
<p id="contain" v-if="show">
  <child></child>
</p>

JS

data () {
  return {
    msg: 'Welcome to Your Vue.js App',
    show:false
  }
},
methods: {
  showchild:function(){
    this.show=true;
  }
},
components: {
  'child': function(resolve) {
    require(['./components/child.vue'], resolve);
  }
}

Note: When loading asynchronous components, do not ignore the .vue after the component name. This example should be more intuitive. After clicking the button, the Boolean value of the variable show is changed to true. Since child.vue is an asynchronous component, the component will be obtained through ajax first and then rendered.
