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
