Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.
前端开发
前端开发规范,包含 Vue 3 编码规范、UI 风格约束、TypeScript 规范等
把这段话发给 Claude Code、Codex 或 Cursor。智能体会先检查安全性,你确认后才安装。
读取 https://funcoding.ai/skills/doccker/cc-use-exp/skills-frontend-dev/install.md ,按里面的步骤帮我安装这个 Skill。

| 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 |
| 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 |
<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>
| 类型 | 约定 | 示例 |
|---|---|---|
| 组件文件 | PascalCase.vue | UserCard.vue |
| Composables | useXxx.ts | useAuth.ts |
| Store | useXxxStore.ts | useUserStore.ts |
// 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 }
})
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>
// types/user.ts
export interface User {
id: number
username: string
role: 'admin' | 'user'
}
export interface ApiResponse<T = unknown> {
code: number
message: string
data: T
}
| 规则 | 说明 |
|---|---|
| ✅ API 工具函数支持泛型 | get<T>(url): Promise<T> 而非返回 unknown |
| ✅ 调用处指定泛型或断言 | get<UserInfo>(url) 或 data as typeof ref.value |
❌ 禁止 as any 绕过 | 掩盖类型问题,后续维护踩坑 |
// ❌ get() 返回 unknown,赋值报 TS2322
const data = await get('/contact/config')
contact.value = data
// ❌ as any 绕过
contact.value = data as any
// ✅ 泛型约束(推荐)
const data = await get<ContactConfig>('/contact/config')
contact.value = data
// ✅ 类型断言(最小改动)
contact.value = data as typeof contact.value
| 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)

| 规则 | 说明 |
|---|---|
❌ 禁止在 .vue 中写大段样式 | <style> 块不超过 20 行 |
❌ 禁止在 .tsx 中写大段内联样式 | 样式对象/CSS-in-JS 不超过 20 行 |
✅ 共享样式抽到 src/assets/styles/ | 按模块拆分文件 |
| ✅ 组件内只保留极简样式 | Vue: scoped 微调;React: className 引用 |
src/assets/styles/
├── variables.scss # 变量(颜色、间距、字号)
├── common.scss # 通用样式
└── [module].scss # 按模块拆分
| 规则 | 说明 |
|---|---|
| ❌ 禁止 UI 可选字段未传入 API | 用户选择/输入的字段必须全部传入请求体 |
| ✅ 提交函数与表单字段一一对应 | 用 TypeScript interface 约束请求体 |
// ❌ UI 有支付方式选择器,但请求体没传 payMethod
const payMethod = ref<'wechat' | 'points' | 'mixed'>('wechat')
async function createOrder() {
await api.createOrder({
items: orderItems.value,
addressId: selectedAddress.value.id,
// payMethod 忘记传了!支付方式选择 UI 形同虚设
})
}
// ✅ 请求体与 UI 表单字段对应
interface CreateOrderRequest {
items: OrderItem[]
addressId: number
payMethod: 'wechat' | 'points' | 'mixed' // 类型约束确保不遗漏
}
async function createOrder() {
const request: CreateOrderRequest = {
items: orderItems.value,
addressId: selectedAddress.value.id,
payMethod: payMethod.value, // TypeScript 会提示缺少字段
}
await api.createOrder(request)
}
| 规则 | 说明 |
|---|---|
| ❌ 禁止静默忽略非成功响应 | res.code !== 200 时必须提示用户 |
| ✅ 统一错误提示 | 非成功响应统一 message.error 提示 |
| ✅ 网络异常也要处理 | try/catch 捕获请求异常 |
// ❌ 只处理成功,非 200 静默忽略
const res = await api.getList(params)
if (res.code === 200) {
list.value = res.data
}
// ✅ 成功 + 失败都处理
try {
const res = await api.getList(params)
if (res.code === 200) {
list.value = res.data
} else {
message.error(res.message || '加载失败')
}
} catch (e) {
message.error('网络异常,请稍后重试')
}
| 规则 | 说明 |
|---|---|
| ❌ 禁止多个文件重复定义相同接口 | PageResponse、BaseResult 等 |
✅ 通用类型统一放 @/types/common.ts | 全局导出,各处引用 |
// ❌ 每个 api 文件都定义一遍
// api/user.ts
interface PageResponse<T> { list: T[]; total: number }
// api/order.ts
interface PageResponse<T> { list: T[]; total: number } // 重复
// ✅ 统一定义,各处引用
// types/common.ts
export interface PageResponse<T> {
list: T[]
total: number
}
// api/user.ts
import type { PageResponse } from '@/types/common'
