示例和模板

此技能包含详细的示例，其组织方式与 NestJS 官方文档结构（https://docs.nestjs.com/）相匹配。所有示例都位于 examples/ 目录中，并按主题组织（参见上面的映射）。

使用示例：

• 从用户的请求中识别主题
• 根据上面的映射加载相应的示例文件
• 遵循该文件中的说明、语法和最佳实践
• 将代码示例调整到您的具体用例

使用模板：

• 参考 templates/ 目录中的模板以进行常见的脚手架搭建
• 模板包括：控制器、提供者、模块、中间件、守卫、管道、拦截器、异常过滤器、DTO 和项目结构
• 根据您的具体需求和编码风格调整模板

最佳实践

1. 使用依赖注入：利用 NestJS 依赖注入容器以获得更好的可测试性和可维护性
2. 按模块组织：将相关功能分组到功能模块中
3. 一致地使用装饰器：遵循 NestJS 的控制器、提供者和路由装饰器模式
4. 验证输入数据：使用 ValidationPipe 和 DTO 进行请求验证
5. 优雅地处理错误：实现全局异常过滤器以进行一致的错误处理
6. 使用守卫进行授权：使用守卫保护路由，而不是内联检查
7. 利用拦截器：使用拦截器处理横切关注点，如日志记录和转换
8. 类型安全：使用 TypeScript 以获得更好的类型安全性和开发体验
9. 全面测试：为服务编写单元测试，为 API 端点编写端到端测试
10. 遵循官方模式：参考官方文档以获取推荐的模式和实践
