Vue路由动态加载

首先新建vue工程，一般我们不会特殊处理路由，但当项目页面越来越多，路由配置也会越来越大，路由文件就会变得不好维护

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,
        }
      ]

    }
  ]
})

这是一个很简单的路由文件，我们先进性第一步优化，按一级菜单分类：

新建test1.router.js文件，放置一级菜单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')这个是配置路由懒加载，优化首屏加载缓慢
在index.js里引入该文件

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
      ]

    }
  ]
})

做到这块，已经可以满足很多项目了，路由文件已经很清晰了，但当项目较大，依然会不清晰

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
      ]

    }
  ]
})
