前端开发规范,包含 Vue 3 编码规范、UI 风格约束、TypeScript 规范等
When & Why to Use This Skill
This Claude skill provides a comprehensive set of frontend development standards and best practices, specifically tailored for Vue 3, TypeScript, and modern UI frameworks like Element Plus. It streamlines the development process by enforcing strict coding conventions, UI constraints, and architectural patterns, ensuring high-quality, maintainable, and performant web applications while eliminating common AI-generated design inconsistencies.
Use Cases
- Standardizing Vue 3 component development using Composition API (<script setup>) and TypeScript to ensure type safety and long-term code readability.
- Enforcing professional UI design systems for enterprise-level dashboards by prohibiting 'AI-style' neon gradients and ensuring clean, functional layouts.
- Implementing scalable state management and API interaction patterns using Pinia and standardized handling for loading, error, and empty states.
- Optimizing frontend performance through industry-standard practices like route lazy loading, virtual scrolling, and efficient reactivity management with shallowRef.

前端开发规范
参考来源: Vue 官方风格指南、Element Plus 最佳实践
UI 风格约束
严格禁止(常见 AI 风格)
- ❌ 蓝紫色霓虹渐变、发光描边、玻璃拟态
- ❌ 大面积渐变、过多装饰性几何图形
- ❌ 赛博风、暗黑科技风、AI 风格 UI
- ❌ UI 文案中使用 emoji
后台系统(默认风格)
| 要素 | 要求 |
|---|---|
| 主题 | 使用组件库默认主题 |
| 配色 | 黑白灰为主 + 1 个主色点缀 |
| 动效 | 克制,仅保留必要交互反馈 |
技术栈
| 层级 | Vue(首选) | React(备选) |
|---|---|---|
| 框架 | Vue 3 + TypeScript | React 18 + TypeScript |
| 构建 | Vite | Vite |
| 路由 | Vue Router 4 | React Router 6 |
| 状态 | Pinia | Zustand |
| UI 库 | Element Plus | Ant Design |
Vue 编码规范
组件基础
<script setup lang="ts">
import { ref, computed, onMounted } from 'vue'
import type { User } from '@/types'
// Props & Emits
const props = defineProps<{ userId: number }>()
const emit = defineEmits<{ (e: 'update', value: string): void }>()
// 响应式状态
const loading = ref(false)
const user = ref<User | null>(null)
// 计算属性
const displayName = computed(() => user.value?.name ?? '未知用户')
// 生命周期
onMounted(async () => { await fetchUser() })
// 方法
async function fetchUser() {
loading.value = true
try {
user.value = await api.getUser(props.userId)
} finally {
loading.value = false
}
}
</script>
<template>
<div class="user-card">
<h3>{{ displayName }}</h3>
</div>
</template>
<style scoped>
.user-card { padding: 16px; }
</style>
命名约定
| 类型 | 约定 | 示例 |
|---|---|---|
| 组件文件 | PascalCase.vue | UserCard.vue |
| Composables | useXxx.ts | useAuth.ts |
| Store | useXxxStore.ts | useUserStore.ts |
状态管理(Pinia)
// stores/user.ts
export const useUserStore = defineStore('user', () => {
const user = ref<User | null>(null)
const token = ref<string>('')
const isLoggedIn = computed(() => !!token.value)
async function login(username: string, password: string) {
const res = await api.login(username, password)
token.value = res.token
user.value = res.user
}
return { user, token, isLoggedIn, login }
})
交互状态处理
必须处理的状态: loading、empty、error、disabled、submitting
<template>
<el-skeleton v-if="loading" :rows="5" animated />
<el-result v-else-if="error" icon="error" :title="error">
<template #extra>
<el-button @click="fetchData">重试</el-button>
</template>
</el-result>
<el-empty v-else-if="list.length === 0" description="暂无数据" />
<template v-else>
<!-- 正常内容 -->
</template>
</template>
TypeScript 规范
// types/user.ts
export interface User {
id: number
username: string
role: 'admin' | 'user'
}
export interface ApiResponse<T = unknown> {
code: number
message: string
data: T
}
性能优化
| 场景 | 方案 |
|---|---|
| 大列表 | 虚拟滚动 |
| 路由 | 懒加载 () => import() |
| 计算 | 使用 computed 缓存 |
| 大数据 | 使用 shallowRef |
// 路由懒加载
const routes = [
{ path: '/dashboard', component: () => import('@/views/Dashboard.vue') }
]
// 请求防抖
import { useDebounceFn } from '@vueuse/core'
const debouncedSearch = useDebounceFn((keyword) => api.search(keyword), 300)
