export interface UserInfo {
userId: number
userName: string
nickName: string
email: string
phonenumber: string
sex: '0' | '1' | '2'
avatar: string
status: '0' | '1'

}
组件Props类型安全
// components/UserTable.vue
<script setup lang="ts">
import { defineProps, withDefaults } from 'vue'
import type { UserInfo } from '@/types/user'
interface Props {
users: UserInfo[]
loading?: boolean
selectable?: boolean
pageSize?: number
}
const props = withDefaults(defineProps<Props>(), {
loading: false,
selectable: false,
pageSize: 10
})
</script>
核心功能实现详解
状态管理：Pinia最佳实践
Store模块化设计
// store/user.ts
import { defineStore } from 'pinia'
import { login, logout, getUserInfo } from '@/api/user'
import type { UserInfo, LoginParams } from '@/types/user'
export const useUserStore = defineStore('user', {
state: (): {
token: string
userInfo: UserInfo | null
permissions: string[]
roles: string[]
} => ({
token: '',
userInfo: null,
permissions: [],
roles: []
}),
getters: {
isLoggedIn: (state) => !!state.token,
userName: (state) => state.userInfo?.userName || '',
avatar: (state) => state.userInfo?.avatar || ''
},
actions: {
async login(loginParams: LoginParams) {
try {
const { token, userInfo } = await login(loginParams)
this.token = token
this.userInfo = userInfo
// 持久化存储
localStorage.setItem('token', token)
} catch (error) {
throw error
}
},
async logout() {
try {
await logout()
} finally {
this.$reset()
localStorage.removeItem('token')
}
},
async getUserInfo() {
if (!this.token) return
const userInfo = await getUserInfo()
this.userInfo = userInfo
}
}
})
路由管理：权限控制体系
路由配置与类型安全
// router/index.ts
import { createRouter, createWebHistory } from 'vue-router'
import type { RouteRecordRaw } from 'vue-router'
export const routes: RouteRecordRaw[] = [
{
path: '/',
component: () => import('@/layout/index.vue'),
redirect: '/index',
children: [
{
path: 'index',
component: () => import('@/views/dashboard/index.vue'),
meta: {
title: '首页',
icon: 'dashboard',
affix: true
}
}
]
},
{
path: '/system',
component: () => import('@/layout/index.vue'),
redirect: '/system/user',
meta: {
title: '系统管理',
icon: 'system',
roles: ['admin']
},
children: [
{
path: 'user',
component: () => import('@/views/system/user/index.vue'),
meta: {
title: '用户管理',
icon: 'user',
roles: ['admin']
}
}
]
}
]
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes
})
// 路由守卫
router.beforeEach(async (to, from, next) => {
const userStore = useUserStore()
if (to.meta.requiresAuth && !userStore.isLoggedIn) {
next('/login')
return
}
if (to.meta.roles && !hasPermission(to.meta.roles)) {
next('/403')
return
}
next()
})
export default router
API请求封装：Axios最佳实践
请求拦截器配置
// utils/request.ts
import axios from 'axios'
import { useUserStore } from '@/store/user'
import { ElMessage } from 'element-plus'
const service = axios.create({
baseURL: import.meta.env.VITE_API_BASE_URL,
timeout: 10000
})
// 请求拦截器
service.interceptors.request.use(
(config) => {
const userStore = useUserStore()
if (userStore.token) {
config.headers.Authorization = `Bearer ${userStore.token}`
}
return config
},
(error) => {
return Promise.reject(error)
}
)
// 响应拦截器
service.interceptors.response.use(
(response) => {
const { data } = response
if (data.code === 200) {
return data.data
} else {
ElMessage.error(data.msg || '请求失败')
return Promise.reject(new Error(data.msg))
}
},
(error) => {
if (error.response?.status === 401) {
const userStore = useUserStore()
userStore.logout()
window.location.href = '/login'
}
ElMessage.error(error.response?.data?.msg || '网络错误')
return Promise.reject(error)
}
)
export default service
高级特性与最佳实践
Composition API深度应用
自定义Hooks封装
// hooks/useTable.ts
import { ref, onMounted } from 'vue'
import type { Ref } from 'vue'
export interface TableState<T> {
loading: Ref<boolean>
data: Ref<T[]>
total: Ref<number>
queryParams: Ref<Record<string, any>>
pagination: Ref<{
page: number
size: number
}>
}
export function useTable<T>(fetchFunction: (params: any) => Promise<{
rows: T[]
total: number
}>) {
const loading = ref(false)
const data = ref<T[]>([]) as Ref<T[]>
const total = ref(0)
const queryParams = ref({})
const pagination = ref({
page: 1,
size: 10
})
const loadData = async () => {
loading.value = true
try {
const params = {
...queryParams.value,
pageNum: pagination.value.page,
pageSize: pagination.value.size
}
const result = await fetchFunction(params)
data.value = result.rows
total.value = result.total
} catch (error) {
console.error('加载数据失败:', error)
} finally {
loading.value = false
}
}
const handleSearch = () => {
pagination.value.page = 1
loadData()
}
const handleReset = () => {
queryParams.value = {}
pagination.value.page = 1
loadData()
}
const handleSizeChange = (size: number) => {
pagination.value.size = size
loadData()
}
const handleCurrentChange = (page: number) => {
pagination.value.page = page
loadData()
}
onMounted(() => {
loadData()
})
return {
loading,
data,
total,
queryParams,
pagination,
loadData,
handleSearch,
handleReset,
handleSizeChange,
handleCurrentChange
}
}
组件开发规范
基于TypeScript的组件开发
<!-- components/DataTable.vue -->
<template>
<div class="data-table">
<el-table
:data="tableData"
v-loading="loading"
@selection-change="handleSelectionChange"
>
<el-table-column
v-if="selectable"
type="selection"
width="55"
/>
<slot name="columns"></slot>
</el-table>
<el-pagination
v-if="showPagination"
:current-page="pagination.page"
:page-size="pagination.size"
:total="total"
layout="total, sizes, prev, pager, next, jumper"
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
/>
</div>
</template>
<script setup lang="ts">
import { ref, watch } from 'vue'
interface Props {
data: any[]
loading?: boolean
total?: number
selectable?: boolean
showPagination?: boolean
page?: number
size?: number
}
const props = withDefaults(defineProps<Props>(), {
loading: false,
total: 0,
selectable: false,
showPagination: true,
page: 1,
size: 10
})
interface Emits {
(e: 'update:page', page: number): void
(e: 'update:size', size: number): void
(e: 'selection-change', selection: any[]): void
}
const emit = defineEmits<Emits>()
const tableData = ref(props.data)
const pagination = ref({
page: props.page,
size: props.size
})
watch(() => props.data, (newData) => {
tableData.value = newData
})
watch(() => props.page, (newPage) => {
pagination.value.page = newPage
})
watch(() => props.size, (newSize) => {
pagination.value.size = newSize
})
const handleSizeChange = (size: number) => {
pagination.value.size = size
emit('update:size', size)
}
const handleCurrentChange = (page: number) => {
pagination.value.page = page
emit('update:page', page)
}
const handleSelectionChange = (selection: any[]) => {
emit('selection-change', selection)
}
</script>
性能优化策略
构建优化配置
// vite.config.ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
export default defineConfig({
plugins: [vue()],
resolve: {
alias: {
'@': resolve(__dirname, 'src')
}
},
build: {
rollupOptions: {
output: {
manualChunks: {
vue: ['vue', 'vue-router', 'pinia'],
element: ['element-plus'],
utils: ['axios', 'dayjs', 'lodash-es']
}
}
},
chunkSizeWarningLimit: 1000
},
server: {
proxy: {
'/api': {
target: 'http://localhost:8080',
changeOrigin: true
}
}
}
})
组件懒加载与代码分割
// 路由懒加载配置
const routes = [
{
path: '/system/user',
component: () => import(/* webpackChunkName: "system-user" */ '@/views/system/user/index.vue')
},
{
path: '/system/role',
component: () => import(/* webpackChunkName: "system-role" */ '@/views/system/role/index.vue')
}
]

实战应用场景
多租户系统前端适配
// composables/useTenant.ts
import { ref } from 'vue'
import { useRoute } from 'vue-router'
export function useTenant() {
const route = useRoute()
const currentTenantId = ref<string>()
const getTenantId = (): string | undefined => {
// 从路由参数、localStorage或全局状态获取租户ID
return route.params.tenantId as string ||
localStorage.getItem('tenantId') ||
currentTenantId.value
}
const setTenantId = (tenantId: string) => {
currentTenantId.value = tenantId
localStorage.setItem('tenantId', tenantId)
}
return {
getTenantId,
setTenantId
}
}
权限按钮控制组件
<!-- components/PermissionButton.vue -->
<template>
<el-button
v-if="hasPermission"
v-bind="$attrs"
@click="$emit('click', $event)"
>
<slot></slot>
</el-button>
</template>
<script setup lang="ts">
import { computed } from 'vue'
import { usePermission } from '@/hooks/usePermission'
interface Props {
permission: string
}
const props = defineProps<Props>()
const { hasPermission } = usePermission()
const hasPermission = computed(() => {
return hasPermission(props.permission)
})
</script>
