Use this skill when

适用场景

  • Designing TypeScript architectures or shared types
  • Solving complex typing, generics, or inference issues
  • Hardening type safety for production systems
  • 设计TypeScript架构或共享类型
  • 解决复杂类型、泛型或推断问题
  • 强化生产系统的类型安全

Do not use this skill when

不适用场景

  • You only need JavaScript guidance
  • You cannot enforce TypeScript in the build pipeline
  • You need UI/UX design rather than type design
  • 仅需要JavaScript指导
  • 无法在构建流程中强制使用TypeScript
  • 需要UI/UX设计而非类型设计

Instructions

操作指南

  1. Define runtime targets and strictness requirements.
  2. Model types and contracts for critical surfaces.
  3. Implement with compiler and linting safeguards.
  4. Validate build performance and developer ergonomics.
  1. 定义运行时目标与严格性要求。
  2. 为关键模块建模类型与契约。
  3. 结合编译器与代码检查保障实现。
  4. 验证构建性能与开发者体验。

Focus Areas

核心领域

  • Advanced type systems (generics, conditional types, mapped types)
  • Strict TypeScript configuration and compiler options
  • Type inference optimization and utility types
  • Decorators and metadata programming
  • Module systems and namespace organization
  • Integration with modern frameworks (React, Node.js, Express)
  • 高级类型系统（泛型、条件类型、映射类型）
  • 严格TypeScript配置与编译器选项
  • 类型推断优化与工具类型
  • 装饰器与元数据编程
  • 模块系统与命名空间组织
  • 与现代框架集成（React、Node.js、Express）

Approach

实施方法

  1. Leverage strict type checking with appropriate compiler flags
  2. Use generics and utility types for maximum type safety
  3. Prefer type inference over explicit annotations when clear
  4. Design robust interfaces and abstract classes
  5. Implement proper error boundaries with typed exceptions
  6. Optimize build times with incremental compilation
  1. 借助合适的编译器标志启用严格类型检查
  2. 使用泛型与工具类型实现最大程度的类型安全
  3. 在清晰明确时优先使用类型推断而非显式注解
  4. 设计健壮的接口与抽象类
  5. 结合类型化异常实现合理的错误边界
  6. 通过增量编译优化构建时间
