  • Vue 搭建vue-element-admin框架

    项目初始化

    vue-element-admin 源码

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

    若npm 报错 Cannot find module 'core-js/modules/es6.regexp.constructor',可安装cnpm install core-js@2识别es6语法

    精简化项目

    • 删除 src/views 下的源码,保留:
      • dashboard:首页
      • error-page:异常页面
      • login:登录
      • 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'
    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 = [
      /** when your routing map is too long, you can split it into small modules **/
      // 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
    
    • 删除 src/router/modules 文件夹
    • 删除 src/vendor 文件夹

    线上项目建议清理components内容,以免影响访问速度,或使用 vue-admin-template 构建项目。这里选择 vue-element-admin 初始化项目,因含有登录模块,包括 token 校验、网络请求等,可以简化开发工作

    项目配置

    通过 src/settings.js 进行全局配置:

    module.exports = {
      title: '后台管理系统',
    
      /**
       * @type {boolean} true | false
       * @description 是否显示控制面板
       */
      showSettings: false,
    
      /**
       * @type {boolean} true | false
       * @description 便签栏
       */
      tagsView: false,
    
      /**
       * @type {boolean} true | false
       * @description 固定头部
       */
      fixedHeader: false,
    
      /**
       * @type {boolean} true | false
       * @description Whether show the logo in sidebar
       */
      sidebarLogo: false,
    
      /**
       * @type {string | array} 'production' | ['production', 'development']
       * @description Need show err logs component.
       * The default is only used in the production env
       * If you want to also use it in dev, you can pass ['production', 'development']
       */
      errorLog: 'production'
    }
    
    • title:站点标题,进入某个页面后,格式为:页面标题 - 站点标题

    • showSettings:是否显示右侧悬浮配置按钮

    • tagsView:是否显示页面标签功能条

    • fixedHeader:是否将头部布局固定

    • sidebarLogo:菜单栏中是否显示LOGO

    • errorLog:默认显示错误日志的环境

    • 自定义页面标题 (vue-element-adminsrcutilsget-page-title.js)

    import defaultSettings from '@/settings'
    
    const title = defaultSettings.title || '后台管理系统'
    
    export default function getPageTitle(pageTitle) {
      if (pageTitle) {
        return `${pageTitle} - ${title}`
      }
      return `${title}`
    }
    
    

    源码调试

    • 如果需要进行源码调试,需要修改 vue.config.js:
    config
      // https://webpack.js.org/configuration/devtool/#development
      .when(process.env.NODE_ENV === 'development',
        config => config.devtool('cheap-source-map')
      )
    
    • 通常建议开发时保持 eval 配置,以增加构建速度,当出现需要源码调试排查问题时改为 source-map
