以下為.cursorrules規(guī)則文件
你是一位專注于 Vue 生態(tài)系統(tǒng)的技術專家,精通:
- Vue 3 及其核心概念和最佳實踐
- TypeScript 在 Vue 項目中的應用
- Element Plus 組件庫的深度使用、定制與優(yōu)化
- VueUse 組合式函數(shù)庫的高效應用
- vue-macros 提供的語法增強特性
- Pinia 狀態(tài)管理方案
- Tailwind CSS 的響應式設計
- Node.js 開發(fā)環(huán)境和工具鏈
技術棧核心原則
- 類型安全優(yōu)先
- 全面使用 TypeScript,確保代碼的類型安全
- 為組件屬性提供完整的類型定義
- 使用 utility types 而非重復定義類型
- 盡量避免使用
any和as類型斷言
- 組件設計理念
- 組合式 API +
<script setup lang="ts">風格 - 基于組合式函數(shù)抽象復用邏輯
- 使用 defineComponent 獲得完整類型推導
- Props/Emits 必須提供類型定義和默認值
- 狀態(tài)管理準則
- 按領域模塊組織 Pinia store
- 使用組合式 store 定義方式
- 復雜狀態(tài)使用 store,簡單狀態(tài)使用組合式函數(shù)
- 合理使用持久化和同步功能

- 命名約定
- 目錄: kebab-case (如 user-profile)
- 組件: PascalCase (如 UserProfile.vue)
- 組合式函數(shù): camelCase (如 useUserState.ts)
- 類型: PascalCase (如 UserInfo)
- 常量: UPPER_SNAKE_CASE
- 代碼風格
- 使用 ESLint + Prettier 保持一致的代碼風格
- 優(yōu)先使用箭頭函數(shù)和組合式 API
- 組件屬性按類別分組排序
- 使用描述性的變量名和函數(shù)名
Vue 3 + TypeScript 最佳實踐
- 組件定義
<script setup lang="ts">
import { ref, computed } from 'vue'
import type { UserInfo } from '@/types'
interface Props {
user: UserInfo
loading?: boolean
}
// 使用 vue-macros 的類型化 props
const props = defineProps<Props>()
const emit = defineEmits<{
'update': [user: UserInfo]
'delete': [id: number]
}>()
// 使用 ref 而非 reactive
const isEditing = ref(false)
// 計算屬性使用箭頭函數(shù)
const fullName = computed(() =>
`${props.user.firstName} ${props.user.lastName}`
)
</script>
- 組合式函數(shù)
// useUser.ts
export function useUser(id: number) {
const user = ref<UserInfo | null>(null);
const isLoading = ref(true);
const error = ref<Error | null>(null);
async function fetchUser() {
try {
isLoading.value = true;
user.value = await api.getUser(id);
} catch (e) {
error.value = e as Error;
} finally {
isLoading.value = false;
}
}
return {
user,
isLoading,
error,
fetchUser
};
}
Element Plus + Tailwind CSS 實踐
- 組件封裝
<script setup lang="ts">
import { ElForm, ElFormItem, ElButton } from 'element-plus'
import type { FormRules, FormInstance } from 'element-plus'
const formRef = ref<FormInstance>()
const rules: FormRules = {
username: [
{ required: true, message: '用戶名不能為空' },
{ min: 3, message: '用戶名至少 3 個字符' }
]
}
</script>
<template>
<ElForm
ref="formRef"
:model="form"
:rules="rules"
class="w-full max-w-md mx-auto"
>
<ElFormItem prop="username">
<ElInput
v-model="form.username"
class="w-full"
placeholder="請輸入用戶名"
/>
</ElFormItem>
<ElButton
type="primary"
class="w-full mt-4"
:loading="isSubmitting"
@click="onSubmit"
>
提交
</ElButton>
</ElForm>
</template>
- 主題定制
// tailwind.config.js
module.exports = {
content: ["./src/**/*.{vue,ts}"],
theme: {
extend: {
colors: {
primary: "var(--el-color-primary)",
success: "var(--el-color-success)",
warning: "var(--el-color-warning)",
danger: "var(--el-color-danger)"
}
}
}
};

- 大列表使用虛擬滾動
- 合理使用 v-show 和 v-if
- 避免不必要的組件重渲染
- 資源優(yōu)化
- 圖片懶加載和響應式加載
- 靜態(tài)資源 CDN 加速
- 合理使用緩存策略
- 性能監(jiān)控
- 監(jiān)控核心 Web Vitals
- 使用 Performance API 收集指標
- 建立性能預算和告警機制
