vue-element-admin配置讲解

1. 项目初始化
   1.git clone https://github.com/PanJiaChen/vue-element-admin
   2.cd vue-element-admin
   3.npm install
   4.npm run dev
2. 项目精简
   删除scr/views下的源码, 保留:
   1.dashboard：首页
   2.error-page：异常页面
   3.login：登录
   4.redirect：重定向
   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
标题旁边的图标在public里面修改

3.2 showSettings
showSettings用来设置是否显示控制面板，设置为false则不显示

image.png

3.3 tagsView
tagsView是我们打开某个页面是否有页面标签

image.png

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

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