首先新建vue工程，一般我們不會特殊處理路由，但當項目頁面越來越多，路由配置也會越來越大，路由文件就會變得不好維護

import Vue from 'vue'import Router from 'vue-router'import HelloWorld from '@/components/HelloWorld'import Home from '@/components/Home'import Test1 from './test1.router.js'import Test2 from '@/components/children/Test2'import Test3 from '@/components/children/Test3' Vue.use(Router) export default new Router({ routes: [  {   path: '/HelloWorld',   name: 'HelloWorld',   component: HelloWorld  },  {   path:'/',   name:'Home',   component:Home,   children:[    {     path:'/test2',     name:'Test2',     component:Test2,    },    {     path:'/test3',     name:'Test3',     component:Test3,    }   ]   } ]})

這是一個很簡單的路由文件，我們先進性第一步優(yōu)化，按一級菜單分類：

新建test1.router.js文件，放置一級菜單test1下的所有路由信息

export default {  path:'/test1',  name:'test1',  component: () => import('@/components/children/Test1'),  children:[]}

component: () => import('@/components/children/Test1')這個是配置路由懶加載，優(yōu)化首屏加載緩慢

在index.js里引入該文件

import Vue from 'vue'import Router from 'vue-router'import HelloWorld from '@/components/HelloWorld'import Home from '@/components/Home'import Test1 from './test1.router.js'import Test2 from './test2.router.js'import Test3 from './test3.router.js'Vue.use(Router)export default new Router({ routes: [  {   path: '/HelloWorld',   name: 'HelloWorld',   component: HelloWorld  },  {   path:'/',   name:'Home',   component:Home,   children:[    Test1,    Test2,    Test3   ]  } ]})

做到這塊，已經(jīng)可以滿足很多項目了，路由文件已經(jīng)很清晰了，但當項目較大，依然會不清晰

import Vue from 'vue'import Router from 'vue-router'import Home from '@/components/Home'Vue.use(Router)let routers = [];let getALLRouterMsg = (paths) => {  paths.keys().forEach(    (key) => routers.push(paths(key).default)  )}getALLRouterMsg(require.context('.',true,//.router/.js/))export default new Router({ routes: [  {   path:'/',   name:'Home',   component:Home,   children:[    ...routers   ]  } ]})
