vue 路由懒加载中给 Webpack Chunks 命名的方法

最早的路由定义方式

import vue from 'vue'
import vuerouter from 'vue-router'

import home from '../views/home.vue'
import about from '../views/about.vue'
import login from '../views/login.vue'

vue.use(vuerouter)

const routes = [
 { path: '/', name: 'home', component: home },
 { path: '/about', name: 'about', component: about },
 { path: '/login', name: 'login', component: login }
]

const router = new vuerouter({
 routes
})

export default router

进化版路由组件懒加载以及定义 chunk name

...
const routes = [
 {
  path: '/',
  name: 'home',
  component: () => import(/* webpackchunkname: "home" */ '../views/home.vue')
 },
 {
  path: '/about',
  name: 'about',
  component: () => import(/* webpackchunkname: "about" */ '../views/about.vue')
 },
 {
  path: '/login',
  name: 'login',
  component: () => import(/* webpackchunkname: "login" */ '../views/login.vue')
 }
]
...

这样写起来是完全没有问题的，但是路由很多的情况下，这里的代码量就会增加，我们能不能把「路径」与「组件」绑定的操作放大循环里面去做呢

const routeoptions = [
 { path: '/', name: 'home' },
 { path: '/about', name: 'about' },
 { path: '/login', name: 'login' }
]
const routes = routeoptions.map(route => {
	return {
		...route,
		component: () => import(`@/views/${route.name}.vue`)
	}
})
const router = new vuerouter({
 routes
})

这样就优雅了不少，但是我们的 chunk name 还没有加上去，这个时候就要用到 webpack 2.6.0 以上的占位符[ index ]和[ request ]

const routeoptions = [
 { path: '/', name: 'home' },
 { path: '/about', name: 'about' },
 { path: '/login', name: 'login' }
]

const routes = routeoptions.map(route => {
 return {
  ...route,
  component: () => import(/* webpackchunkname: "[request]" */ `../views/${route.name}.vue`)
 }
})

const router = new vuerouter({
 routes
})

build 一下就能看到想要的 chunk 了
