Vue面试题： 如何实现路由懒加载？

import List from '@/components/list.vue'
const router = new VueRouter({
  routes: [
    { path: '/list', component: List }
  ]
})

const List = () => import('@/components/list.vue')
const router = new VueRouter({
  routes: [
    { path: '/list', component: List }
  ]
})

const router = new Router({
  routes: [
   {
     path: '/list',
     component: (resolve) => {
        // 这里是你的模块 不用import去引入了
        require(['@/components/list'], resolve)
     }
    }
  ]
})

// r就是resolve
const List = r => require.ensure([], () => r(require('@/components/list')), 'list');
// 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 router = new Router({
  routes: [
  {
    path: '/list',
    component: List,
    name: 'list'
  }
 ]
}))
