1. 项目初始化

git clone https://github.com/PanJiaChen/vue-element-admin
cd vue-element-admin
npm install 
npm run dev  

2. 项目精简

1. 删除scr/views下的源码, 保留:

   • dashboard：首页
   • error-page：异常页面
   • login：登录
   • redirect：重定向

2. 对src/router/index 进行相应修改

   import Vue from 'vue'
   import Router from 'vue-router'
   
   Vue.use(Router)
   
   /* Layout */
   import Layout from '@/layout'
   
   /**
    * Note: sub-menu only appear when route children.length >= 1
    * Detail see: https://panjiachen.github.io/vue-element-admin-site/guide/essentials/router-and-nav.html
    *
    * hidden: true                   if set true, item will not show in the sidebar(default is false)
    * alwaysShow: true               if set true, will always show the root menu
    *                                if not set alwaysShow, when item has more than one children route,
    *                                it will becomes nested mode, otherwise not show the root menu
    * redirect: noRedirect           if set noRedirect will no redirect in the breadcrumb
    * name:'router-name'             the name is used by <keep-alive> (must set!!!)
    * meta : {
       roles: ['admin','editor']    control the page roles (you can set multiple roles)
       title: 'title'               the name show in sidebar and breadcrumb (recommend set)
       icon: 'svg-name'             the icon show in the sidebar
       noCache: true                if set true, the page will no be cached(default is false)
       affix: true                  if set true, the tag will affix in the tags-view
       breadcrumb: false            if set false, the item will hidden in breadcrumb(default is true)
       activeMenu: '/example/list'  if set path, the sidebar will highlight the path you set
     }
    */
   
   /**
    * constantRoutes
    * a base page that does not have permission requirements
    * all roles can be accessed
    */
   export const constantRoutes = [
     {
       path: '/redirect',
       component: Layout,
       hidden: true,
       children: [
         {
           path: '/redirect/:path(.*)',
           component: () => import('@/views/redirect/index')
         }
       ]
     },
     {
       path: '/login',
       component: () => import('@/views/login/index'),
       hidden: true
     },
     {
       path: '/auth-redirect',
       component: () => import('@/views/login/auth-redirect'),
       hidden: true
     },
     {
       path: '/404',
       component: () => import('@/views/error-page/404'),
       hidden: true
     },
     {
       path: '/401',
       component: () => import('@/views/error-page/401'),
       hidden: true
     },
     {
       path: '/',
       component: Layout,
       redirect: '/dashboard',
       children: [
         {
           path: 'dashboard',
           component: () => import('@/views/dashboard/index'),
           name: 'Dashboard',
           meta: { title: 'Dashboard', icon: 'dashboard', affix: true }
         }
       ]
     }
   ]
   
   /**
    * asyncRoutes
    * the routes that need to be dynamically loaded based on user roles
    */
   export const asyncRoutes = [
     // 404 page must be placed at the end !!!
     { path: '*', redirect: '/404', hidden: true }
   ]
   
   const createRouter = () => new Router({
     // mode: 'history', // require service support
     scrollBehavior: () => ({ y: 0 }),
     routes: constantRoutes
   })
   
   const router = createRouter()
   
   // Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
   export function resetRouter() {
     const newRouter = createRouter()
     router.matcher = newRouter.matcher // reset router
   }
   
   export default router
   
   

3. 删除 src/router/modules 文件夹

4. 删除 src/vendor文件夹

3. 项目配置

进入src目录下的settings.js配置文件

module.exports = {
  title: 'Project Title',
  showSettings: true,
  tagsView: true,
  fixedHeader: false,
  sidebarLogo: false,
  errorLog: 'production'
}

3.1 项目标题

在src/settings.js 配置项目标题

3.2 showSettings

showSettings用来设置是否显示控制面板，设置为false则不显示

3.3 tagsView

tagsView是我们打开某个页面是否有页面标签

3.4 fixedHeader

fixedHeader是内容页面向下滑动时头部是否固定，false是不固定， true是固定

3.5 sidebarLogo

sidebarLogo控制菜单栏上方是否显示图标

3.6 源码调试

打开vue.config.js文件
找到如下图的位置

cheap-source-map调试模式没有完全编译展示我们的源代码

我们改成source-map调试模式，这时候再来看Sources的App.vue文件，已经和源代码显示的一样，在这样的环境下调试我们会更加方便
但是source-map有一个缺点，每当我们程序有改动时，也需要同步生成source-map文件，这样会使我们构建变慢，在实际开发过程中推荐使用eval,以增加构建速度 在需要调试的时候使用source-map

4. 项目结构分析

1. api ：接口请求
2. assets ：一些静态文件
3. components ： 封装组件
4. direcetive ：自定义指令
5. filters ：过滤器
6. icons ：图标
7. layout ：全局框架组件(非常重要)
8. router ：路由
9. store ：配置vuex
10. styles ：全局样式文件
11. utils ：工具类
12. views ：页面组件
13. App.vue ：父组件，其他的组件都是嵌套在App.vue里
14. main.js ：全局入口文件，将App.vue设置为全局父组件进行渲染
15. permissions.js ：登录的校验和登录之后的路由跳转
16. setting.js ：配置文件
