Summary of asynchronous loading methods of vue+webpack

This time I will bring you a summary of the asynchronous loading method of vue webpack. What are the precautions for asynchronous loading of vue webpack? 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);
  }
}

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
