一、环境准备

1.1 node.js 安装

node.js 官方下载地址

1.2 包管理工具安装：可选

• npm：

  node.js 中自带，速度较慢

• yarn：

# cmd 全局安装 yarn
npm install -g yarn 

二、创建项目

选择要创建项目的目录，打开cmd 执行以下命令

2.1 使用 npm

npm init vite@latest 
# npm 6.x
npm init vite@latest 项目名称 --template vue
# npm 7+, 需要额外的双横线：
npm init vite@latest 项目名称 -- --template vue

2.2 使用 yarn

# 方式一
yarn create vite
# 方式二
yarn create vite 项目名称 --template vue
# 方式三：该方式可直接配置需要的组件，可减少依赖版本冲突
npm init vue
# npm init vue 提示如下：
✔ Project name: … <your-project-name>
✔ Add TypeScript? … No / Yes
✔ Add JSX Support? … No / Yes
✔ Add Vue Router for Single Page Application development? … No / Yes
✔ Add Pinia for state management? … No / Yes
✔ Add Vitest for Unit testing? … No / Yes
✔ Add Cypress for both Unit and End-to-End testing? … No / Yes
✔ Add ESLint for code quality? … No / Yes
✔ Add Prettier for code formatting? … No / Yes

Scaffolding project in ./<your-project-name>...
Done.

三、配置项目

3.1 安装初始依赖

# npm
npm install
# yarn
yarn init

3.2 增加依赖

yarn： yarn add 依赖名称

npm： npm install 依赖名称

# 异步请求包
yarn add axios
# scss 解析器，也可使用 less 等
yarn add sass -d
# 自动导包插件
yarn add unplugin-auto-import -d
yarn add unplugin-icons -d
yarn add unplugin-vue-components -d

}

3.2 配置自动导包

// vite.config.ts
import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import Icons from 'unplugin-icons/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
import path from 'path'

export default defineConfig({
  base: '/',
  server: {
    open: true,
    // 修改端口号
    port: 8080, 
    proxy: {
        // 后端微服务时可在此处配置代理，解决测试环境跨域问题
    },
  },
  plugins: [
    vue(),
    AutoImport({
      imports: ['vue', 'vue-router', 'pinia'],
      resolvers: [ElementPlusResolver()],
      eslintrc: {
        enabled: true, // Default `false`
      },
    }),
    Components({
      resolvers: [ElementPlusResolver()],
      // 默认组件加载
      dirs: ['src/**/*.vue', 'src/**/*.ts', 'src/**/*.d.ts'],
      // 全局导入组件
      globs: [ 
        'src/layout/**/*.vue',
        'src/layout/**/*.ts',
        'src/layout/**/*.d.ts',
      ],
      extensions: ['vue', 'ts'],
    }),
    Icons({
      /* options */
    }),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url)),
    },
  },
})

配置后会在根目录下自动生成以下文件：

• components.d.ts

  组件库自动导入、自定义组件自动导入

• auto-imports.d.ts

  vue 相关方法自动注入

• .prettierrc

  prettier 规则

• .eslintrc.cjs

  eslint 规则

• .eslintrc-auto-import.json

  auto-imports 自动插件生成的 eslint 规则，需要在 eslint 中引入

3.3 配置 eslint 规则

// .eslintrc.cjs
require('@rushstack/eslint-patch/modern-module-resolution')

module.exports = {
  root: true,
  'extends': [
    'plugin:vue/vue3-essential',
    'eslint:recommended',
    '@vue/eslint-config-typescript',
    '@vue/eslint-config-prettier/skip-formatting',
    // 引入 auto-imports 自动生成的规则
    './.eslintrc-auto-import.json'  
  ],
  parserOptions: {
    ecmaVersion: 'latest'
  },
  rules: {
    'prettier/prettier': [
      'error',
      {
        arrowParens: 'always',
        bracketSameLine: true,
        bracketSpacing: true,
        embeddedLanguageFormatting: 'auto',
        htmlWhitespaceSensitivity: 'ignore',
        insertPragma: false,
        jsxSingleQuote: true,
        printWidth: 80,
        proseWrap: 'preserve',
        quoteProps: 'as-needed',
        requirePragma: false,
        semi: false,
        singleAttributePerLine: false,
        singleQuote: true,
        tabWidth: 2,
        trailingComma: 'es5',
        useTabs: false,
        vueIndentScriptAndStyle: false,
      },
    ],
      // 设置文件命名可以为单个单词 
      'vue/multi-word-component-names': 0
  },
}

3.4 .vue 文件导入报错解决

// env.d.ts
/// <reference types="vite/client" />
interface ImportMetaEnv {
  readonly VITE_APP_BASE_API: string
  readonly VITE_APP_DEV_USER: string
  readonly VITE_APP_DEV_PWD: string
  // more env variables...
}

interface ImportMeta {
  readonly env: ImportMetaEnv
}

declare module '*.vue' // .vue 文件引入报错解决

四、路由配置

该 layout 仅供参考，可按需求自行替换

src/router:

• index.ts

  路由主要加载文件，可引入自定义路由文件

• system.ts

  根据用户需求自定义路由文件，定义完成后在 index 中引入

4.1 路由类型定义

// types/route.d.ts
// This can be directly added to any of your `.ts` files like `router.ts`
// It can also be added to a `.d.ts` file, in which case you will need to add an export
// to ensure it is treated as a module
export {}

import 'vue-router'

declare module 'vue-router' {
  interface RouteMeta {
    // 标题
    title: string
    // 图标
    icon?: string
    // 访问权限
    perms?: string[]
    // 是否在菜单中,默认在,设置为true则不在
    hidden?: boolean
    // 是否忽略子菜单全都被过滤掉导致的不显示,设置为true时忽略
    alwaysShow?: boolean
    // 是否在角色管理中不显示
    roleManageIgnore?: boolean
  }
}

4.2 index.ts 路由主入口

// src/router/index.ts
import { createRouter, createWebHistory, type RouteRecordRaw } from 'vue-router'
import system from '@/router/system' // 自定义路由文件

// 静态路由
export const commonRoutes: RouteRecordRaw[] = [
  {
    path: '/layout',
    name: 'Layout',
    component: () => import('@/layout/Home.vue'),
    meta: {
      title: '首页',
      hidden: true,
    },
    children: [
      {
        path: '/dashboard',
        name: 'dashboard',
        component: () => import('@/views/Dashboard.vue'),
        meta: {
          title: '首页',
          hidden: true,
        },
      },
    ],
  },
  {
    path: '/',
    redirect: '/login',
    meta: {
      title: '登录重定向',
      hidden: true,
    },
  },
  {
    path: '/login',
    name: 'login',
    component: () => import('@/components/login/Login.vue'),
    meta: {
      title: '登录',
      hidden: true,
    },
  },
  {
    path: '/404',
    name: '404',
    component: () => import('@/components/error/404.vue'),
    meta: {
      title: '404',
      hidden: true,
    },
  },
  {
    path: '/401',
    name: '401',
    component: () => import('@/components/error/401.vue'),
    meta: {
      title: '401',
      hidden: true,
    },
  },
]

// 将静态路由 和 自定义路由进行整合
export const allRoutes: RouteRecordRaw[] = [...commonRoutes, system]

const router = createRouter({
  history: createWebHistory(),
  routes: allRoutes,
})

export default router

4.3 system.ts 自定义路由

// src/router/system.ts
import type { RouteRecordRaw } from 'vue-router'
import Home from '@/layout/Home.vue'

// 该路由文件的最顶层路由
export const systemRoute: RouteRecordRaw = {
  path: '/system',
  name: 'system',
  meta: {
    title: '系统管理',
  },
  component: Home,
}

export const userRoute: RouteRecordRaw = {
  path: '/user',
  name: 'user',
  meta: {
    title: '用户管理',
  },
  component: () => import('@/views/system/user/user.vue'),
}
export const roleRoute: RouteRecordRaw = {
  path: '/role',
  name: 'role',
  meta: {
    title: '角色管理',
  },
  component: () => import('@/views/system/role/role.vue'),
}
export const logRoute: RouteRecordRaw = {
  path: '/log',
  name: 'log',
  meta: {
    title: '日志管理',
  },
  component: () => import('@/views/system/log/log.vue'),
}

export default <RouteRecordRaw>{
  ...systemRoute,
  children: [userRoute, roleRoute, logRoute],
}

五、常用类型定义

5.1 response.d.ts

// src/model/response.d.ts
// 父接口， 不返回对象
export interface BaseResponse {
  success: boolean
  code: number
  message?: string
}

// 用于返回一个对象
export interface ItemResponse<T> extends BaseResponse {
  item?: T
}

// 用于返回一个List
export interface ListResponse<T> extends BaseResponse {
  items: T[]
}

// 用于返回含分页的 list
export interface PageResponse<T> extends BaseResponse {
  pageNum: number
  pageSize: number
  total: number
  totalPages?: number
  items?: T[]
}

5.2 user.d.ts 自定义返回类型

// 用户信息，用于存放在全局变量
export interface UserInfo {
  username: string
  name: string
  phone?: string
  email?: string
}
// 登录的用户
export interface LoginUser {
  username: string
  password: string
}

// 注册用户
export interface RegisterUser {
  username: string
  password: string
  name: string
  sex: string
  email: string
  phone: string
  checkPassword: string
}

六、二次封装 axios

6.1 httpClient.ts

// src/utils/httpClient.ts
import axios, { type AxiosRequestConfig } from 'axios'
import type { BaseResponse } from '@/model/response'

const httpClient = axios.create({
  // 设置默认请求地址
  baseURL: import.meta.env.VITE_APP_BASE_API,
  // 设置超时时间
  timeout: import.meta.env.DEV ? 10000 : 10000,
  // 跨域时允许携带凭证
  withCredentials: true,
})

// 添加请求拦截器
httpClient.interceptors.request.use(
  (config) => {
    // 在发送请求之前做些什么
    return config
  },
  (error) => {
    // 对请求错误做些什么
    return Promise.reject(error)
  }
)

// 添加响应拦截器
httpClient.interceptors.response.use(
  (response) => {
    // 2xx 范围内的状态码都会触发该函数。
    // 对响应数据做点什么
    return response
  },
  (error) => {
    // 超出 2xx 范围的状态码都会触发该函数。
    // 对响应错误做点什么
    return Promise.reject(error)
  }
)

export function post(
  url: string,
  data?: any,
  config?: AxiosRequestConfig<any>
) {
  return httpClient.post<never, BaseResponse>(url, data, config)
}

export function put(url: string, data?: any, config?: AxiosRequestConfig<any>) {
  return httpClient.put<never, BaseResponse>(url, data, config)
}

export function get(url: string, config?: AxiosRequestConfig<any>) {
  return httpClient.get<never, BaseResponse>(url, config)
}

export function del(url: string, config?: AxiosRequestConfig<any>) {
  return httpClient.delete<never, BaseResponse>(url, config)
}

export default httpClient

6.2 httpClient 实例

// src/api/user.ts
import httpClient from '@/utils/httpClient'
// 以下类型在 src/model 中定义
import type { BaseResponse, ItemResponse } from '@/model/response'
import type { LoginUser, RegisterUser, UserInfo } from '@/model/user'

/**
 * 登录
 * @param user 用户
 * @returns {BaseResponse} 登录结果
 */
export const login: (user: LoginUser) => Promise<ItemResponse<UserInfo>> = (
  user
) => {
  return httpClient.post('/api/gateway/login', null, {
    params: {
      username: user.username,
      password: user.password,
    },
  })
}

/**
 * @param user
 */
export const logout: () => Promise<BaseResponse> = () => {
  return httpClient.get('/api/gateway/logout')
}

/**
 * 注册
 * @param user 用户
 * @returns {Promise<BaseResponse>} 注册结果
 */
export const register: (
  user: RegisterUser
) => Promise<ItemResponse<RegisterUser>> = (user) => {
  return httpClient.post('/api/gateway/user-service/user/registerUser', user)
}

七、本地响应式存储

7.1 定义

• user.ts

// src/stores/user.ts
// 用户相关
import type { LoginUser, UserInfo } from '@/model/user'
import { login } from '@/api/user' // api 中封装的登录请求

export const userStore = defineStore('user', () => {
   // 用户信息
  const userInfo = ref<UserInfo | null>(null)
  // 登录后获取用户信息
  async function loginUser(user: LoginUser) {
    try {
      const res = await login(user)
      const { success, code, item } = res
      if (success && code == 200) {
        userInfo.value = item!
      }
      return Promise.resolve(res)
    } catch (error: any) {
      return Promise.reject(error)
    }
  }
  // 对外暴漏的属性及方法
  return { userInfo, loginUser }
})

• permission.ts

// src/stores/permission.ts
// 权限相关
import { allRoutes } from '@/router'
import type { RouteRecordRaw } from 'vue-router'

export const permissionStore = defineStore('permission', () => {
  const perms = ref<string[]>([])

  // 这个用于后面 layout 中根据用户权限生成菜单
  const authorizedRoutes = computed(() => {
    // 根据权限过滤路由
    const filterRoutes = filterAsyncRoutes(perms.value, allRoutes)
    return filterRoutes
  })

  function setPermission(newPermission: string[]) {
    perms.value = newPermission
  }

  function $reset() {
    perms.value = []
  }

  return { perms, $reset, setPermission, authorizedRoutes }
})

export function filterAsyncRoutes(
  perms: string[],
  routes: RouteRecordRaw[]
): RouteRecordRaw[] {
  const result = <RouteRecordRaw[]>[]
  routes.forEach((e) => {
    const route = <RouteRecordRaw>{ ...e }
    if (hasPermission(perms, route)) {
      if (route.children) {
        route.children = filterAsyncRoutes(perms, route.children)
      }
      result.push(route)
    }
  })
  return result
}

/**
 * Use meta.perms to determine if the current user has permission
 * @param perms
 * @param route
 */
function hasPermission(perms: string[], route: RouteRecordRaw) {
  if (route.meta && route.meta.perms) {
    // 如果该路由设置了权限，检查用户权限
    return perms.some((perm) => route.meta?.perms?.includes(perm))
  } else {
    // 如果该路由没有设置权限，则默认所有人可见
    return true
  }
}

7.2 调用

• 页面中使用

<!-- 该页面属于 layout 中 -->
<!-- src/layout/Header.vue -->
<template>
  <div class="header">
    <el-header>
      <Breadcrumb />
        <!-- 使用本地存储中的属性 -->
      <div>{{ userStore().userInfo?.name || '测试' }}</div>
    </el-header>
  </div>
</template>

<script setup lang="ts">
// 引入 userStore
import { userStore } from '@/stores/user'
</script>

• ts 中使用

<!-- 该页面属于 layout 中 -->
<!-- src/layout/menu/menu.ts -->
import { isExternal } from '@/utils/validate'
import { allRoutes } from '@/router'
import type { RouteRecordRaw } from 'vue-router'
import { permissionStore } from '@/stores/permission'

export const useMenu = () => {
  const menus = computed(() => {
    // 使用本地存储获取用户权限 
    const routes: RouteRecordRaw[] = permissionStore().authorizedRoutes
    // 根据权限匹配路由
    console.log(routes)
    console.log(generateMenuFromRoute(routes))
    return generateMenuFromRoute(routes)
  })
  return { menus }
}

八、全局样式

8.1 样式重置

  </el-config-provider>
</template>

<style scoped lang="scss">
/* 引入 reset.scss */
@import '@/assets/style/reset'; 
</style>

8.2 样式常量

8.2.1 variables.scss

// src/styles/variables.scss
// base
$testWith: 200px;

8.2.2 常量使用

// src/styles/test.scss
// 导入 variables.scss
@import "variables.scss";
.test{
  width: $testWith; // 使用中定义的样式常量
}

九、layout

9.1 面包屑

<!-- src/layout/Breadcrumb.vue -->
<template>
  <div class="breadcrumb">
    <el-breadcrumb class="app-breadcrumb" separator=">">
      <transition-group name="breadcrumb">
        <el-breadcrumb-item
          v-for="(item, index) in route!.matched"
          :key="index">
          <span
            v-if="
              item.redirect === 'noRedirect' ||
              index == route!.matched.length - 1
            "
            class="no-redirect">
            {{ item.meta.title }}
          </span>
          <!-- 放开后可点击 -->
          <!-- <a v-else @click.prevent="handleLink(item)">{{ item.meta.title }}</a> -->
          <span v-else>{{ item.meta.title }}</span>
        </el-breadcrumb-item>
      </transition-group>
    </el-breadcrumb>
  </div>
</template>

<script lang="ts" setup>
import { useRoute } from 'vue-router'
const route = useRoute()
</script>

<style scoped lang="scss">
@import '@/styles/layout';
</style>

9.2 导航栏

<!-- src/layout/Header.vue -->
<template>
  <div class="header">
    <el-header>
       <!-- 面包屑 自动导入 -->
      <Breadcrumb />
      <div>{{ userStore().userInfo?.name || '测试' }}</div>
    </el-header>
  </div>
</template>

<script setup lang="ts">
import { userStore } from '@/stores/user'
</script>

<style lang="scss" scoped>
@import '@/styles/layout';
</style>

9.3 侧边栏

• menu.ts

// src/layout/menu/menu.ts
// 将菜单中的逻辑封装，简化页面代码
import { isExternal } from '@/utils/validate'
import { allRoutes } from '@/router'
import type { RouteRecordRaw } from 'vue-router'
import { permissionStore } from '@/stores/permission'

export interface Menu {
   // 标题
   title: string
   // 图标
   icon?: string
   // 路径
   path: string
   // 子目录
   children?: Menu[]
   // 隐藏
   hidden?: boolean
   // 外链
   external?: boolean
}

// 出口方法，获取到 Menu 对象
export const useMenu = () => {
   const menus = computed(() => {
       // TODO 获取用户权限
       const routes: RouteRecordRaw[] = permissionStore().authorizedRoutes
       // 根据权限匹配路由
       console.log(routes)
       console.log(generateMenuFromRoute(routes))
       return generateMenuFromRoute(routes)
   })
   return { menus }
}

// 根据路由控制菜单显示
const generateMenuFromRoute = (
  routes: RouteRecordRaw[],
  parent?: Menu
): Menu[] => {
  const result: Menu[] = []
  routes.forEach((route) => {
    // 如果路由隐藏直接返回
    if (route.meta?.hidden) {
      return
    }
    // 将当前路由转换为 menu
    const menu: Menu = routeToMenu(route, parent?.path)
    if (route.children && route.children.length > 0) {
      menu.children = generateMenuFromRoute(route.children, menu)
    }
    result.push(menu)
  })

  return result
}

// 路由转化为 Menu 对象
const routeToMenu = (route: RouteRecordRaw, basePath?: string): Menu => {
  let path: string
  if (route.path.startsWith('/')) {
    // / 开头为 / 是绝对路径
    path = route.path
  } else {
    if (route.path == '') {
      // 空路由则返回父路由
      path = basePath ?? ''
    } else {
      // 没有 / 则为相对路径
      path = basePath + '/' + route.path
    }
  }
  return <Menu>{
    title: route.meta?.title ?? '',
    icon: route.meta?.icon,
    path: path,
    external: isExternal(route.path),
    hidden: route.meta?.hidden,
  }
}

• SideMenuItem.vue

<!-- src/layout/menu/SideMenuItem.vue -->
 <!-- 递归生成菜单 -->
 <template>
   <div>
     <el-sub-menu v-if="item.children" :index="item.path">
       <template #title>
         {{ item.title }}
       </template>
       <side-menu-item
         v-for="menu in item.children"
         :key="menu.path"
         :item="menu" />
     </el-sub-menu>
     <el-menu-item v-else :index="item.path">
       <i :class="item.icon"></i>
       {{ item.title }}
     </el-menu-item>
   </div>
 </template>
 
 <script setup lang="ts">
 import type { Menu } from '@/layout/menu/menu'
 // 父传子属性
 const props = defineProps<{
   item: Menu
 }>()
 </script>

• SideBar.vue

<!-- src/layout/menu/SideBar.vue -->
<!-- 侧边栏结构 -->
<template>
  <div class="sideBar">
    <div class="title">后台管理系统</div>
    <el-scrollbar>
      <el-menu text-color="#fff" background-color="#304156" router>
        <side-menu-item v-for="menu in menus" :key="menu.path" :item="menu" />
      </el-menu>
    </el-scrollbar>
  </div>
</template>

<script setup lang="ts">
import { useMenu } from '@/layout/menu/menu'
const { menus } = useMenu()
</script>

<style scoped lang="scss">
@import '@/styles/layout';
</style>

9.4 页脚

<!-- src/layout/Footer.vue -->
<template>
  <div class="footer">
    <el-card>Frontend 2022 dily</el-card>
  </div>
</template>

<script lang="ts" setup></script>

<style scoped lang="scss"></style>

9.5 主体结构

由 面包屑、侧边栏、导航栏、页脚搭建组合成

<!-- src/layout/Home.vue -->
<template>
  <div class="common-layout">
    <el-container>
      <el-aside>
        <side-bar />
      </el-aside>
      <el-container>
        <Header />
        <el-main>
          <div class="cont">
            <router-view v-slot="{ Component, route }">
              <transition name="fade-transform" mode="out-in">
                <keep-alive :include="cachedViews">
                  <component :is="Component" :key="route.path" />
                </keep-alive>
              </transition>
            </router-view>
          </div>
        </el-main>
        <el-footer>
          <Footer />
        </el-footer>
      </el-container>
    </el-container>
  </div>
</template>
<script setup lang="ts">
const cachedViews = ref<string[]>([])
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style lang="scss" scoped>
@import '@/styles/layout';
</style>

十、错误页面
