Core Principles
核心原则
- Write idiomatic Go code following Go conventions
- Utilize Go 1.22+ features including new routing capabilities
- Follow RESTful API design principles
- Implement proper error handling with custom error types when beneficial
- 遵循Go编写规范,编写地道的Go代码
- 利用Go 1.22+的新特性,包括新增的路由功能
- 遵循RESTful API设计原则
- 在合适的场景下使用自定义错误类型实现恰当的错误处理
Code Organization
代码组织
- Clean Architecture principles with handlers, services, repositories, and domain models
- Interface-driven development with explicit dependency injection
- Modular project structure:
- cmd/ - Application entry points
- internal/ - Private application code
- pkg/ - Public libraries
- api/ - API definitions
- configs/ - Configuration files
- test/ - Test files
- 遵循整洁架构原则,包含处理器、服务、仓库和领域模型
- 基于接口的开发,实现显式依赖注入
- 模块化项目结构:
- cmd/ - 应用程序入口
- internal/ - 私有应用代码
- pkg/ - 公共库
- api/ - API定义
- configs/ - 配置文件
- test/ - 测试文件
API Development
API开发
- Use the standard library's package
net/http - Leverage Go 1.22's new ServeMux with wildcard matching and regex support
- Implement proper HTTP method handling (GET, POST, PUT, DELETE)
- Input validation and JSON response formatting
- Middleware implementation for logging and authentication
- 使用标准库的包
net/http - 利用Go 1.22新增的ServeMux,支持通配符匹配和正则表达式
- 实现恰当的HTTP方法处理(GET、POST、PUT、DELETE)
- 输入验证和JSON响应格式化
- 实现用于日志记录和身份验证的中间件
Error Handling
错误处理
- Use wrapped errors for traceability
- Implement explicit error handling
- Return errors rather than panicking
- Provide meaningful error messages
- Handle errors at appropriate levels
- 使用包装错误以实现可追溯性
- 实现显式错误处理
- 返回错误而非触发panic
- 提供有意义的错误信息
- 在合适的层级处理错误
Concurrency
并发
- Goroutine safety and context propagation
- Use channels for communication between goroutines
- Implement proper cancellation with context
- Avoid race conditions with proper synchronization
- Goroutine安全和上下文传播
- 使用通道在Goroutine之间进行通信
- 利用上下文实现恰当的取消操作
- 通过恰当的同步避免竞态条件
Testing
测试
- Table-driven unit testing patterns
- Integration testing for APIs
- Mocking with interfaces
- Use testing package effectively
- 表驱动单元测试模式
- API集成测试
- 基于接口的Mocking
- 有效使用testing包
DevOps Integration
DevOps集成
- Linting with golangci-lint
