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-admin\src\utils\get-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

项目结构

  • api:接口请求
  • assets:静态资源
  • components:通用组件
  • directive:自定义指令
