项目初始化与基础配置

创建Vue 3项目

使用Vite创建Vue 3项目的最佳实践：

# 使用npm
npm create vite@latest my-vue-app -- --template vue

# 使用yarn
yarn create vite my-vue-app --template vue

# 使用pnpm
pnpm create vite my-vue-app --template vue

项目结构规划

典型的现代化Vue 3项目结构：

src/
├── assets/              # 静态资源
├── components/          # 公共组件
├── composables/         # 可复用逻辑
├── layouts/             # 布局组件
├── pages/               # 页面组件
├── router/              # 路由配置
├── stores/              # 状态管理
├── styles/              # 样式文件
├── utils/               # 工具函数
├── views/               # 视图组件
├── App.vue              # 根组件
└── main.js              # 入口文件

Vite配置优化

基础的vite.config.js配置：

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

export default defineConfig({
  plugins: [
    vue(),
    vueJsx(),
    AutoImport({
      resolvers: [ElementPlusResolver()]
    }),
    Components({
      resolvers: [ElementPlusResolver()]
    })
  ],
  server: {
    port: 3000,
    host: true,
    proxy: {
      '/api': {
        target: 'http://localhost:8080',
        changeOrigin: true,
        rewrite: (path) => path.replace(/^\/api/, '')
      }
    }
  },
  build: {
    rollupOptions: {
      output: {
        manualChunks: {
          vendor: ['vue', 'vue-router', 'pinia'],
          element: ['element-plus']
        }
      }
    }
  }
})

Pinia状态管理实践

Pinia核心概念

Pinia是Vue官方推荐的状态管理库，相比Vuex具有更轻量、更易用的特点：

// stores/user.js
import { defineStore } from 'pinia'

export const useUserStore = defineStore('user', {
  state: () => ({
    userInfo: null,
    isLoggedIn: false,
    permissions: []
  }),
  
  getters: {
    userName: (state) => state.userInfo?.name || '',
    hasPermission: (state) => (permission) => {
      return state.permissions.includes(permission)
    }
  },
  
  actions: {
    async login(credentials) {
      try {
        const response = await fetch('/api/login', {
          method: 'POST',
          headers: { 'Content-Type': 'application/json' },
          body: JSON.stringify(credentials)
        })
        
        const data = await response.json()
        this.userInfo = data.user
        this.isLoggedIn = true
        this.permissions = data.permissions
        
        // 存储到localStorage
        localStorage.setItem('userToken', data.token)
        
        return data
      } catch (error) {
        throw new Error('登录失败')
      }
    },
    
    logout() {
      this.userInfo = null
      this.isLoggedIn = false
      this.permissions = []
      localStorage.removeItem('userToken')
    }
  }
})

多状态模块管理

创建多个状态模块以满足复杂业务需求：

// stores/app.js
import { defineStore } from 'pinia'

export const useAppStore = defineStore('app', {
  state: () => ({
    loading: false,
    theme: 'light',
    language: 'zh-CN'
  }),
  
  actions: {
    setLoading(status) {
      this.loading = status
    },
    
    toggleTheme() {
      this.theme = this.theme === 'light' ? 'dark' : 'light'
    }
  }
})

// stores/setting.js
import { defineStore } from 'pinia'

export const useSettingStore = defineStore('setting', {
  state: () => ({
    sidebarCollapsed: false,
    notifications: []
  }),
  
  actions: {
    toggleSidebar() {
      this.sidebarCollapsed = !this.sidebarCollapsed
    },
    
    addNotification(notification) {
      this.notifications.push({
        id: Date.now(),
        ...notification,
        timestamp: new Date()
      })
    }
  }
})

状态持久化

实现状态的持久化存储：

// utils/persist.js
import { createPinia } from 'pinia'

export function setupPersist(pinia) {
  pinia.use(({ store }) => {
    // 从localStorage恢复状态
    const savedState = localStorage.getItem(`pinia-${store.$id}`)
    if (savedState) {
      store.$patch(JSON.parse(savedState))
    }
    
    // 监听状态变化并保存到localStorage
    store.$subscribe((mutation, state) => {
      localStorage.setItem(`pinia-${store.$id}`, JSON.stringify(state))
    })
  })
}

// main.js
import { createApp } from 'vue'
import { createPinia } from 'pinia'
import { setupPersist } from './utils/persist'

const app = createApp(App)
const pinia = createPinia()

setupPersist(pinia)
app.use(pinia)

组件化设计模式

可复用逻辑组合式函数

使用Composition API创建可复用的逻辑：

// composables/useApi.js
import { ref, reactive } from 'vue'

export function useApi() {
  const loading = ref(false)
  const error = ref(null)
  
  const request = async (url, options = {}) => {
    try {
      loading.value = true
      error.value = null
      
      const response = await fetch(url, {
        headers: {
          'Content-Type': 'application/json',
          ...options.headers
        },
        ...options
      })
      
      if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`)
      }
      
      const data = await response.json()
      return data
    } catch (err) {
      error.value = err.message
      throw err
    } finally {
      loading.value = false
    }
  }
  
  return {
    loading,
    error,
    request
  }
}

// composables/usePagination.js
import { ref, computed } from 'vue'

export function usePagination(initialPage = 1, initialPageSize = 10) {
  const currentPage = ref(initialPage)
  const pageSize = ref(initialPageSize)
  const total = ref(0)
  
  const totalPages = computed(() => Math.ceil(total.value / pageSize.value))
  
  const setPage = (page) => {
    if (page >= 1 && page <= totalPages.value) {
      currentPage.value = page
    }
  }
  
  const setPageSize = (size) => {
    pageSize.value = size
    currentPage.value = 1
  }
  
  return {
    currentPage,
    pageSize,
    total,
    totalPages,
    setPage,
    setPageSize
  }
}

组件通信模式

实现多种组件间通信方式：

<!-- components/DataTable.vue -->
<template>
  <div class="data-table">
    <el-table :data="tableData" v-loading="loading">
      <el-table-column prop="name" label="姓名"></el-table-column>
      <el-table-column prop="email" label="邮箱"></el-table-column>
      <el-table-column label="操作">
        <template #default="{ row }">
          <el-button @click="handleEdit(row)">编辑</el-button>
          <el-button type="danger" @click="handleDelete(row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
    
    <el-pagination
      v-model:current-page="pagination.currentPage"
      v-model:page-size="pagination.pageSize"
      :total="pagination.total"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
    />
  </div>
</template>

<script setup>
import { ref, watch } from 'vue'
import { useApi } from '@/composables/useApi'

const props = defineProps({
  apiPath: {
    type: String,
    required: true
  }
})

const emit = defineEmits(['row-edit', 'row-delete'])

const { loading, request } = useApi()
const tableData = ref([])
const pagination = reactive({
  currentPage: 1,
  pageSize: 10,
  total: 0
})

// 加载数据
const loadData = async () => {
  try {
    const response = await request(`${props.apiPath}?page=${pagination.currentPage}&size=${pagination.pageSize}`)
    tableData.value = response.data
    pagination.total = response.total
  } catch (error) {
    console.error('加载数据失败:', error)
  }
}

// 监听分页变化
watch([() => pagination.currentPage, () => pagination.pageSize], loadData)

// 处理分页事件
const handleSizeChange = (size) => {
  pagination.pageSize = size
  loadData()
}

const handleCurrentChange = (page) => {
  pagination.currentPage = page
  loadData()
}

const handleEdit = (row) => {
  emit('row-edit', row)
}

const handleDelete = (row) => {
  emit('row-delete', row)
}

// 初始化加载数据
loadData()
</script>

路由系统设计

路由配置最佳实践

// router/index.js
import { createRouter, createWebHistory } from 'vue-router'
import { useUserStore } from '@/stores/user'

const routes = [
  {
    path: '/',
    redirect: '/dashboard'
  },
  {
    path: '/login',
    name: 'Login',
    component: () => import('@/views/Login.vue'),
    meta: { requiresAuth: false }
  },
  {
    path: '/dashboard',
    name: 'Dashboard',
    component: () => import('@/views/Dashboard.vue'),
    meta: { requiresAuth: true, title: '仪表板' }
  },
  {
    path: '/users',
    name: 'Users',
    component: () => import('@/views/Users.vue'),
    meta: { requiresAuth: true, permissions: ['user:view'], title: '用户管理' }
  },
  {
    path: '/settings',
    name: 'Settings',
    component: () => import('@/views/Settings.vue'),
    meta: { requiresAuth: true, permissions: ['setting:view'], title: '系统设置' }
  }
]

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

// 路由守卫
router.beforeEach((to, from, next) => {
  const userStore = useUserStore()
  
  // 需要认证的路由
  if (to.meta.requiresAuth && !userStore.isLoggedIn) {
    next('/login')
    return
  }
  
  // 权限检查
  if (to.meta.permissions && to.meta.permissions.length > 0) {
    const hasPermission = to.meta.permissions.some(permission => 
      userStore.hasPermission(permission)
    )
    
    if (!hasPermission) {
      next('/403')
      return
    }
  }
  
  next()
})

export default router

动态路由加载

实现懒加载和动态路由：

// router/dynamic.js
import { defineAsyncComponent } from 'vue'

const asyncRoute = (path, component) => {
  return defineAsyncComponent(() => import(`@/views/${path}/${component}.vue`))
}

export const dynamicRoutes = [
  {
    path: '/reports',
    name: 'Reports',
    component: asyncRoute('Reports', 'Index'),
    meta: { requiresAuth: true, title: '报表中心' }
  },
  {
    path: '/analytics',
    name: 'Analytics',
    component: asyncRoute('Analytics', 'Dashboard'),
    meta: { requiresAuth: true, title: '数据分析' }
  }
]

工程化配置与优化

构建优化策略

// vite.config.js (构建优化)
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { visualizer } from 'rollup-plugin-visualizer'

export default defineConfig({
  plugins: [
    vue(),
    visualizer({
      filename: 'dist/stats.html',
      open: true
    })
  ],
  build: {
    assetsDir: 'assets',
    rollupOptions: {
      output: {
        // 分块策略
        manualChunks: {
          vendor: ['vue', 'vue-router', 'pinia', 'element-plus'],
          utils: ['axios', 'lodash', 'dayjs'],
          charts: ['echarts', 'chart.js']
        }
      }
    },
    // 生产环境压缩
    minify: 'terser',
    terserOptions: {
      compress: {
        drop_console: true,
        drop_debugger: true
      }
    }
  }
})

环境变量管理

// .env.development
VITE_API_BASE_URL=http://localhost:8080/api
VITE_APP_NAME=My Enterprise App
VITE_APP_VERSION=1.0.0

// .env.production
VITE_API_BASE_URL=https://api.myapp.com/api
VITE_APP_NAME=My Enterprise App
VITE_APP_VERSION=1.0.0

// utils/config.js
export const config = {
  apiUrl: import.meta.env.VITE_API_BASE_URL,
  appName: import.meta.env.VITE_APP_NAME,
  appVersion: import.meta.env.VITE_APP_VERSION
}

TypeScript配置

// tsconfig.json
{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "moduleResolution": "Node",
    "strict": true,
    "jsx": "preserve",
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "useDefineForClassFields": true,
    "lib": ["ES2020", "DOM", "DOM.Iterable"],
    "types": ["vite/client"],
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "include": ["src/**/*", "src/**/*.vue"],
  "exclude": ["node_modules"]
}

性能监控与调试

开发环境调试工具

// utils/debug.js
export const debug = {
  log: (message, data) => {
    if (import.meta.env.DEV) {
      console.log(`[DEBUG] ${message}`, data)
    }
  },
  
  error: (message, error) => {
    if (import.meta.env.DEV) {
      console.error(`[ERROR] ${message}`, error)
    }
  },
  
  time: (label) => {
    if (import.meta.env.DEV) {
      console.time(label)
    }
  },
  
  timeEnd: (label) => {
    if (import.meta.env.DEV) {
      console.timeEnd(label)
    }
  }
}

性能监控实现

// composables/usePerformance.js
import { ref, onMounted } from 'vue'

export function usePerformance() {
  const performanceData = ref({
    memory: null,
    fps: 0,
    loadTime: 0
  })
  
  const startMonitoring = () => {
    if ('performance' in window) {
      const observer = new PerformanceObserver((list) => {
        list.getEntries().forEach((entry) => {
          if (entry.entryType === 'navigation') {
            performanceData.value.loadTime = entry.loadEventEnd - entry.loadEventStart
          }
        })
      })
      
      observer.observe({ entryTypes: ['navigation'] })
    }
  }
  
  onMounted(() => {
    startMonitoring()
  })
  
  return {
    performanceData
  }
}

安全性最佳实践

XSS防护

// utils/sanitize.js
import DOMPurify from 'dompurify'

export function sanitizeHtml(html) {
  return DOMPurify.sanitize(html, {
    ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'ul', 'ol', 'li'],
    ALLOWED_ATTR: ['class', 'id']
  })
}

// 在组件中使用
import { sanitizeHtml } from '@/utils/sanitize'

const processedContent = computed(() => {
  return sanitizeHtml(props.content)
})

请求安全

// utils/api.js
import axios from 'axios'
import { useUserStore } from '@/stores/user'

const api = axios.create({
  baseURL: import.meta.env.VITE_API_BASE_URL,
  timeout: 10000
})

// 请求拦截器
api.interceptors.request.use(
  (config) => {
    const userStore = useUserStore()
    if (userStore.isLoggedIn) {
      config.headers.Authorization = `Bearer ${localStorage.getItem('userToken')}`
    }
    return config
  },
  (error) => {
    return Promise.reject(error)
  }
)

// 响应拦截器
api.interceptors.response.use(
  (response) => response,
  (error) => {
    if (error.response?.status === 401) {
      // 未授权，跳转到登录页
      window.location.href = '/login'
    }
    return Promise.reject(error)
  }
)

export default api
