Vue项目构建开发笔记（vue-lic3.0构建的）

1、router.js里面

{
      path: '/about',
      name: 'about',
      // route level code-splitting
      // this generates a separate chunk (about.[hash].js) for this route
      // which is lazy-loaded when the route is visited.
      component: () => import(/* webpackChunkName: "about" */ './views/About.vue')
    }

webpackChunkName

注释的webpackChunkName就类似于起了一个别名

把组件按组分块 （webpackChunkName的妙用）

有时候我们想把某个路由下的所有组件都打包在同个异步块 (chunk) 中。只需要使用 命名 chunk，一个特殊的注释语法来提供 chunk name (需要 Webpack > 2.4)。

const Foo = () => import(/* webpackChunkName: "group-foo" */ './Foo.vue')
const Bar = () => import(/* webpackChunkName: "group-foo" */ './Bar.vue')
const Baz = () => import(/* webpackChunkName: "group-foo" */ './Baz.vue')
