vue项目打包优化--路由懒加载

同过路由懒加载可以实现vue组件按需加载，缩短首次进入等待时间

vue 路由懒加载的配置示例如下：

import Vue from 'vue'
import Router from 'vue-router'
import { resolve } from 'path';

Vue.use(Router)

export default new Router({
    routes: [{
            path: '/baseMain',
            component: resolve => require(['@/components/projectManage/baseMain'],resolve),
            children: [
                {
                    name:'projectList',
                    path: '/projectList',
                    component: resolve => require(['@projManage/projectAdmin/projectList'],resolve),
                },
                {
                    name:'projectDetails',
                    path: '/projectList/projectDetails',
                    component: resolve => require(['@projManage/projectAdmin/projectDetails'],resolve)
                },
                {
                    name:'frontResource',
                    path: '/frontResource',
