Vue Router的懒加载路径的解决方法

const AsyncCom = () => Promise.resolve({ /* component definition */ })

require.ensure([AYNC_MODULE_PATH], CALLBACK, CHUNK_NAME)

const AsyncCom = resolve => require.ensure([], () => resolve(require(AYNC_MODULE_PATH)), CHUNK_NAME);
webpack>=2的版本可以通过import()来指定动态引入的模块
import('./A.vue') // returns a Promise

// const A = resolve => require.ensure([], () => resolve(require('./a.vue')), 'A');
const A = () => import('./a.vue')
const router = new VueRouter({
 routes: [
  { path: '/a', component: A }
 ]
})

const A = () => import(/* webpackChunkName: "group-a-b-c" */ './a.vue')
const B = () => import(/* webpackChunkName: "group-a-b-c" */ './b.vue')
const C = () => import(/* webpackChunkName: "group-a-b-c" */ './c.vue')
// webpack.conf.js
output: {
     ......
    // 使用code-split产出的chunk文件名
    chunkFilename: utils.assetsPath('js/[chunkname].[chunkhash].chunk.js'),
    ......
}
