Constraints
约束条件
MUST DO
必须遵循
- Use Composition API (NOT Options API)
- Use syntax for components
<script setup> - Use type-safe props with TypeScript
- Use for primitives,
ref()for objectsreactive() - Use for derived state
computed() - 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)
- 组件使用语法
<script setup> - 结合TypeScript使用类型安全的Props
- 基本类型使用,对象使用
ref()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
