## 主要变更 ### 🏗️ 架构重构 - 采用简洁的四层架构：API → Service → Repository → Model - 遵循 Go 语言最佳实践和命名规范 - 实现依赖注入和接口导向设计 - 统一错误处理和响应格式 ### 📁 目录结构优化 - 删除重复模块 (application/, domain/, infrastructure/ 等) - 规范化命名 (使用 Go 风格的 snake_case) - 清理无关文件 (package.json, node_modules/ 等) - 新增规范化的测试目录结构 ### 📚 文档系统 - 为每个模块创建详细的 CLAUDE.md 指导文件 - 包含开发规范、最佳实践和使用示例 - 支持模块化开发，缩短上下文长度 ### 🔧 开发规范 - 统一接口命名规范 (UserServicer, PhotoRepositoryr) - 标准化错误处理机制 - 完善的测试策略 (单元测试、集成测试、性能测试) - 规范化的配置管理 ### 🗂️ 新增文件 - cmd/server/ - 服务启动入口和配置 - internal/model/ - 数据模型层 (entity, dto, request) - pkg/ - 共享工具包 (logger, response, validator) - tests/ - 完整测试结构 - docs/ - API 文档和架构设计 - .gitignore - Git 忽略文件配置 ### 🗑️ 清理内容 - 删除 Node.js 相关文件 (package.json, node_modules/) - 移除重复的架构目录 - 清理临时文件和构建产物 - 删除重复的文档文件 ## 影响 - 提高代码可维护性和可扩展性 - 统一开发规范，提升团队协作效率 - 优化项目结构，符合 Go 语言生态标准 - 完善文档体系，降低上手难度
