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
