Core Workflow

核心工作流程

  1. Analyze requirements - Identify component hierarchy, state needs, routing
  2. Design architecture - Plan composables, stores, component structure
  3. Implement - Build components with Composition API and proper reactivity
  4. Optimize - Minimize re-renders, optimize computed properties, lazy load
  5. Test - Write component tests with Vue Test Utils and Vitest
  1. 需求分析 - 确定组件层级、状态需求及路由
  2. 架构设计 - 规划组合式函数、状态仓库及组件结构
  3. 开发实现 - 使用Composition API构建组件并确保正确的响应式
  4. 性能优化 - 减少重渲染、优化计算属性、实现懒加载
  5. 测试验证 - 使用Vue Test Utils和Vitest编写组件测试

Constraints

约束条件

MUST DO

必须遵循

  • Use Composition API (NOT Options API)
  • Use
    <script setup>
    syntax for components
  • Use type-safe props with TypeScript
  • Use
    ref()
    for primitives,
    reactive()
    for objects
  • Use
    computed()
    for derived state
  • Use proper lifecycle hooks (onMounted, onUnmounted, etc.)
  • Implement proper cleanup in composables
  • Use Pinia for global state management
  • 使用Composition API(禁止使用Options API)
  • 组件使用
    <script setup>
    语法
  • 结合TypeScript使用类型安全的Props
  • 基本类型使用
    ref()
    ,对象使用
    reactive()
  • 派生状态使用
    computed()
  • 使用正确的生命周期钩子(onMounted、onUnmounted等)
  • 在组合式函数中实现适当的清理逻辑
  • 使用Pinia进行全局状态管理

MUST NOT DO

禁止操作

  • Use Options API (data, methods, computed as object)
  • Mix Composition API with Options API
  • Mutate props directly
  • Create reactive objects unnecessarily
  • Use watch when computed is sufficient
  • Forget to cleanup watchers and effects
  • Access DOM before onMounted
  • Use Vuex (deprecated in favor of Pinia)
  • 使用Options API(以对象形式定义data、methods、computed)
  • 混合使用Composition API与Options API
  • 直接修改Props
  • 不必要地创建响应式对象
  • 在可使用computed的场景下使用watch
  • 忘记清理watchers和effects
  • 在onMounted之前访问DOM
  • 使用Vuex(已被Pinia替代)

Output Templates

输出模板

When implementing Vue features, provide:
  1. Component file with
    <script setup>
    and TypeScript
