vue-cli + webpack2 + Vue-Router2打包文件过大的优化

1、Webpack2 + Vue2 + Vue-Router2 如何实现懒加载?

const Main = resolve => require(['./components/Main.vue'], resolve)
const Home = resolve => require(['./components/Home.vue'], resolve)

const router = new VueRouter({
    mode: 'hash',
    base: __dirname,
    scrollBehavior,
    routes: [
        { name:'main', path: 'main', component: Main },
        { name:'home', path: 'home', component: Home }
    ]
})
