vue 路由懒加载 resolve vue-router配置

使用方法

component:resolve => require(['@/pages/About'],resolve)      //"@"相当于".."

 

懒加载

router/index.js

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
 
export default new Router({
  mode:'history',
  routes: [
    {
      path:'/',
      redirect:'/index'
    },
    {
      path: '/about',
      name: 'About',
      component:resolve => require(['@/pages/About'],resolve)
    },
    {
      path: '/index',
      name: 'Index',
      component:resolve => require(['@/pages/Index'],resolve)
    },
    {
      path: '/product',
      name: 'Product',
      component:resolve => require(['@/pages/Product'],resolve)
    }
  ]
})

 

非懒加载

router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import About from '@/pages/About'
import Index from '@/pages/Index'
import Product from '@/pages/Product'
Vue.use(Router)
 
export default new Router({
  mode:'history',
  routes: [
    {
      path:'/',
      redirect:'/index'
    },
    {
      path: '/about',
      name: 'About',
      component:About
    },
    {
      path: '/index',
      name: 'Index',
      component:Index
    },
    {
      path: '/product',
      name: 'Product',
      component:Product
    }
  ]
})

 

如果用import引入的话,当项目打包时路由里的所有component都会打包在一个js中,造成进入首页时,需要加载的内容过多,时间相对比较长。
当你用require这种方式引入的时候,会将你的component分别打包成不同的js,加载的时候也是按需加载,只用访问这个路由网址时才会加载这个js。
你可以打包的时候看看目录结构就明白了。
