1、创建项目更改版本

1-1、创建项目

vue create vue3-admin

1-2、更改vue版本

更改前

更改后

2、开发项目

1、按需引入element-plus

1、安装

npm install element-plus --save

2、按需导入（自动导入）

cnpm install -D unplugin-vue-components unplugin-auto-import

3、Webpack配置（vue.config.js）

const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')

module.exports = {
intOnSave:false,
  devServer:{
    open:true,
    port:9000,
  },
  configureWebpack: {
    plugins: [
      AutoImport({
        resolvers: [ElementPlusResolver()],
      }),
      Components({
        resolvers: [ElementPlusResolver()],
      }),
    ]
  },
}

4、使用

tips:在main.js中引入样式（避免弹出框等组件样式错乱）

import 'element-plus/dist/index.css'

2、使用element-plus Icon图标

1、安装

cnpm install @element-plus/icons-vue

2、注册全局组件

//main.js
import * as ELIcons from '@element-plus/icons-vue'
for (const iconName in ELIcons) {
  app.component(iconName, ELIcons[iconName])
}

3、使用（左侧菜单icon）

<template #title>
   <el-icon>
    <component :is="iconList[index]"></component>
   </el-icon>
   <span>{{ item.authName }}</span>
</template>

3、样式初始化，使用scss变量

1、导入初始样式,导出变量值

2、在main.js中引入

import '@/styles/index.scss'

3、配置webpack

css: {
    loaderOptions: {
      sass: {
        // 8版本用prependData:
        prependData: `
          @import "@/styles/variables.scss";  // scss文件地址
          @import "@/styles/mixin.scss";     // scss文件地址
        `
      }
    }
  }

4、使用svg，全局注册

1、svg图标导入到项目

2、在components文件夹下创建SvgIcon组件

<template>
  <svg class="svg-icon" aria-hidden="true">
    <use :xlink:href="iconName"></use>
  </svg>
</template>

<script setup>
import { defineProps, computed } from 'vue'
const props = defineProps({
  icon: {
    type: String,
    required: true
  }
})

const iconName = computed(() => {
  return `#icon-${props.icon}`
})
</script>

<style lang="scss" scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}
</style>

4、在icons 文件夹下新建index.js

import SvgIcon from '@/components/SvgIcon'

const svgRequired = require.context('./svg', false, /\.svg$/)
svgRequired.keys().forEach((item) => svgRequired(item))

export default (app) => {
  app.component('svg-icon', SvgIcon)
}

5、在main.js中引入

import SvgIcon from '@/icons'
const app=createApp(App)
SvgIcon(app)

6、安装依赖

cnpm i --save-dev svg-sprite-loader@6.0.9

7、配置webpack

const path = require('path')
function resolve(dir) {
  return path.join(__dirname, dir)
}
const webpack = require('webpack')

module.exports = {
chainWebpack(config) {
    // 设置 svg-sprite-loader
    // config 为 webpack 配置对象
    // config.module 表示创建一个具名规则，以后用来修改规则
    config.module
      // 规则
      .rule('svg')
      // 忽略
      .exclude.add(resolve('src/icons'))
      // 结束
      .end()
    // config.module 表示创建一个具名规则，以后用来修改规则
    config.module
      // 规则
      .rule('icons')
      // 正则，解析 .svg 格式文件
      .test(/\.svg$/)
      // 解析的文件
      .include.add(resolve('src/icons'))
      // 结束
      .end()
      // 新增了一个解析的loader
      .use('svg-sprite-loader')
      // 具体的loader
      .loader('svg-sprite-loader')
      // loader 的配置
      .options({
        symbolId: 'icon-[name]'
      })
      // 结束
      .end()
    config
      .plugin('ignore')
      .use(
        new webpack.ContextReplacementPlugin(/moment[/\\]locale$/, /zh-cn$/)
      )
    config.module
      .rule('icons')
      .test(/\.svg$/)
      .include.add(resolve('src/icons'))
      .end()
      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end()
  },
}

8、使用

<svg-icon icon="user" class="svg-container"></svg-icon>

5、请求封装

1、安装axios

cnpm i axios --save

2、新建utils文件夹，新建auth.js设置过期时间

const TOKEN_TIME = 'tokenTime'

const TOKEN_TIME_VALUE = 2 * 60 * 60 * 1000

// 登录时设置时间
export const setTokenTime = () => {
  localStorage.setItem(TOKEN_TIME, Date.now())
}

// 获取
export const getTokenTime = () => {
  return localStorage.getItem(TOKEN_TIME)
}

// 是否已经过期
export const diffTokenTime = () => {
  const currentTime = Date.now()
  const tokenTime = getTokenTime()
  return currentTime - tokenTime > TOKEN_TIME_VALUE
}

3、新建api文件夹，新建request.js文件

import axios from 'axios'
import { ElMessage } from 'element-plus'
import { diffTokenTime } from '@/utils/auth'
import store from '@/store'
const service = axios.create({
  baseURL: process.env.VUE_APP_BASE_API,
  timeout: 5000
})

service.interceptors.request.use(
  (config) => {
    if (localStorage.getItem('token')) {
      if (diffTokenTime()) {
        store.dispatch('app/logout')
        return Promise.reject(new Error('token 失效了'))
      }
    }
    config.headers.Authorization = localStorage.getItem('token')
    return config
  },
  (error) => {
    return Promise.reject(new Error(error))
  }
)

service.interceptors.response.use(
  (response) => {
    const { data, meta } = response.data
    if (meta.status === 200 || meta.status === 201) {
      return data
    } else {
      ElMessage.error(meta.msg)
      return Promise.reject(new Error(meta.msg))
    }
  },
  (error) => {
    console.log(error.response)
    error.response && ElMessage.error(error.response.data)
    return Promise.reject(new Error(error.response.data))
  }
)
export default service

4、本地跨域配置

  devServer: {
    https: false,
    hotOnly: false,
    open:true,
    port:9000,
    proxy: {
      '/api': {
        target: 'https://*******/api/private/v1/',
        changeOrigin: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    }
  },

5、全局坏境变量定义

新建 .env.development、.env.production文件

ENV = 'development'

VUE_APP_BASE_API = '/api'

ENV = 'production'

VUE_APP_BASE_API = '/prod-api'

6、全局导航守卫

import { createRouter, createWebHashHistory } from 'vue-router'

const routes = [
  {
    path: '/login',
    name: 'Login',
    component: () => import('../views/login/index.vue')
  },
  {
    path: '/',
    name: '/',
    component: () => import('../layout'),
    redirect: '/users',
    children: [
      {
        path: 'users',
        name: 'users',
        component: () => import('@/views/users/index.vue')
      },
      {
        path: 'categories',
        name: 'categories',
        component: () => import('@/views/categories/index.vue')
      },
      {
        path: 'goods',
        name: 'goods',
        component: () => import('@/views/goods/index.vue')
      },
      {
        path: 'orders',
        name: 'orders',
        component: () => import('@/views/orders/index.vue')
      },
      {
        path: 'params',
        name: 'params',
        component: () => import('@/views/params/index.vue')
      },
      {
        path: 'reports',
        name: 'reports',
        component: () => import('@/views/reports/index.vue')
      },
      {
        path: 'rights',
        name: 'rights',
        component: () => import('@/views/rights/index.vue')
      },
      {
        path: 'roles',
        name: 'roles',
        component: () => import('@/views/roles/index.vue')
      }
    ]
  }
]


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

export default router

1、新建router/permission.js

import router from './index'
import store from '@/store'

const whiteList = ['/login']
router.beforeEach((to, from, next) => {
  if (store.getters.token) {
    if (to.path === '/login') {
      next('/')
    } else {
      next()
    }
  } else {
    if (whiteList.includes(to.path)) {
      next()
    } else {
      next('/login')
    }
  }
})

2、main.js引入

import '@/router/permission'

5、登录

1、新增登录界面login/index.vue

<template>
  <div class="login-container">
    <el-form ref="loginFormRef" :model="loginForm" class="login-form" :rules="rules">
      <div class="title-container">
        <h3 class="title">后台管理系统</h3>
      </div>
      <el-form-item prop="username">
        <svg-icon icon="user" class="svg-container"></svg-icon>
        <el-input v-model="loginForm.username"></el-input>
      </el-form-item>
      <el-form-item prop="password">
        <svg-icon icon="password" class="svg-container"></svg-icon>
        <el-input v-model="loginForm.password" :type="passwordType"></el-input>
        <svg-icon
          class="svg-container"
          :icon="passwordType === 'password' ? 'eye' : 'eye-open'"
          @click="changeType"
        ></svg-icon>
      </el-form-item>
      <el-button type="primary" class="login-button" @click="handleLogin">登录</el-button>
    </el-form>
  </div>
</template>

<script setup>
import { ref,reactive} from 'vue'
import { useStore } from 'vuex'
const store = useStore()
const loginForm = reactive({
  username: 'admin',
  password: '123456'
})

const rules = reactive({
  username: [
    { required: true, message: '请输入用户名', trigger: 'blur' },
  ],
  password: [
    {
      required: true,
      message: '请输入密码',
      trigger: 'blur'
    }
  ]
})

const loginFormRef = ref(null)
const handleLogin = () => {
  loginFormRef.value.validate(async (valid) => {
    if (valid) {
      store.dispatch('app/login', loginForm)
    } else {
      console.log('error submit!!')
      return false
    }
  })
}

const passwordType = ref('password')
const changeType = () => {
  if (passwordType.value === 'password') {
    passwordType.value = 'text'
  } else {
    passwordType.value = 'password'
  }
}
</script>

    font-size: 16px;
    color: $dark_gray;
    cursor: pointer;
    user-select: none;
  }
}
</style>

2、新建api/login.js

import request from './request'

export const login = (data) => {
  return request({
    url: '/login',
    method: 'POST',
    data
  })
}

3、新建store/modules/app.js

import { login as loginApi } from '@/api/login'
import router from '@/router'
import { setTokenTime } from '@/utils/auth'
export default {
  namespaced: true,
  state: () => ({
    token: localStorage.getItem('token') || '',
    siderType: true,
  }),
  mutations: {
    setToken(state, token) {
      state.token = token
      localStorage.setItem('token', token)
    },
    changeSiderType(state) {
      state.siderType = !state.siderType
    },
  },
  actions: {
    login({ commit }, userInfo) {
      return new Promise((resolve, reject) => {
        loginApi(userInfo)
          .then((res) => {
            console.log(res)
            commit('setToken', res.token)
            setTokenTime()
            router.replace('/')
            resolve()
          })
          .catch((err) => {
            reject(err)
          })
      })
    },
    // 退出
    logout({ commit }) {
      commit('setToken', '')
      localStorage.clear()
      router.replace('/login')
    }
  }
}

4、store/getters.js、store/index.js

export default {
  token: (state) => state.app.token,
  siderType: (state) => state.app.siderType,
}

import { createStore } from 'vuex'
import app from './modules/app'
import getters from './getters'
export default createStore({
  modules: {
    app
  },
  getters
})

3、Layout 布局

<template>
    <el-container class="content_wrapper">
      <el-aside :width="asideWidth" class="sidebar-container">
        <Menu />
      </el-aside>
      <el-container
      class="right_container"
      :class="{ hidderContainer: !$store.getters.siderType }"
    >
      <el-header><Headers /></el-header>
      <el-main>
        <router-view />
      </el-main>
    </el-container>
    </el-container>
</template>


<script setup>
import Menu from './Menu'
import Headers from './headers'
import { computed } from 'vue'
import variables from '@/styles/variables.scss'
import { useStore } from 'vuex'
const store = useStore()
// const asideWidth = ref(variables.sideBarWidth)
const asideWidth = computed(() => {
  return store.getters.siderType
    ? variables.sideBarWidth
    : variables.hideSideBarWidth
})
</script>

<style lang="scss" scoped>

  .content_wrapper{
     width: 100%;
    height: 100%;
    display: flex;
    align-items: center;
    :deep(.sidebar-container){
      flex-shrink: 0;
    }
    :deep(.right_container){
      flex:1;
      height: 100%;
    }
  }

</style>

1、左侧菜单新建layout/Menu/index.vue

<template>
  <el-menu
    active-text-color="#ffd04b"
    :background-color="variables.menuBg"
    class="el-menu-vertical-demo"
    :default-active="defaultActive"
    text-color="#fff"
    router
    unique-opened
    :collapse="!$store.getters.siderType"
  >
    <el-sub-menu
      :index="item.id+''"
      v-for="(item, index) in menusList"
      :key="item.id"
    >
      <template #title>
        <el-icon>
          <component :is="iconList[index]"></component>
        </el-icon>
        <span>{{ item.authName }}</span>
      </template>
      <el-menu-item
        :index="'/' + it.path"
        v-for="it in item.children"
        :key="it.id"
        @click="savePath(it.path)"
      >
        <template #title>
          <el-icon>
            <component :is="icon"></component>
          </el-icon>
          <span>{{  it.authName  }}</span>
        </template>
      </el-menu-item>
    </el-sub-menu>
  </el-menu>
</template>

<script setup>
import { menuList } from '@/api/menu'
import { ref } from 'vue'
import variables from '@/styles/variables.scss'

const iconList = ref(['user', 'setting', 'shop', 'tickets', 'pie-chart'])
const icon = ref('menu')

const defaultActive = ref(sessionStorage.getItem('path') || '/users')
const menusList = ref([])
const initMenusList = async () => {
  menusList.value = await menuList()
}
initMenusList()

const savePath = (path) => {
  sessionStorage.setItem('path', `/${path}`)
}
</script>

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

  if(!isNull(val)){
    val = parseInt(val)*1000
    return dayjs(val).format(format)
  }else{
    return '--'
  }
}

export const isNull = (val)=>{
  if(!val) return true
  if(JSON.stringify(val)==="{}") return true
  if(JSON.stringify(val)==="[]") return true
}

export default (app)=>{
  app.config.globalProperties.$filters={
    filterTimes
  }
}

3、main.js传入app

import filters from './utils/filters'
filters(app)

4、使用

<template v-slot="{row}" v-else-if="item.prop=='create_time'">
   {{$filters.filterTimes(row.create_time)}}
</template>
