Vue路由動態加載

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，已經可以滿足很多項目了，路由文件已經很清晰了，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
      ]

    }
  ]
})
