nestjs core module guidelines

NestJS核心模块准则

When reviewing or writing code, apply these guidelines:
  • Global filters for exception handling.
  • Global middlewares for request management.
  • Guards for permission management.
  • Interceptors for request management.
在审查或编写代码时，请遵循以下准则：
  • 使用全局过滤器处理异常
  • 使用全局中间件管理请求
  • 使用守卫进行权限管理
  • 使用拦截器管理请求

nestjs general guidelines

NestJS通用准则

When reviewing or writing code, apply these guidelines:
  • Use modular architecture
  • Encapsulate the API in modules.
    • One module per main domain/route.
    • One controller for its route.
    • And other controllers for secondary routes.
    • A models folder with data types.
    • DTOs validated with class-validator for inputs.
    • Declare simple types for outputs.
    • A services module with business logic and persistence.
    • One service per entity.
  • A core module for nest artifacts
    • Global filters for exception handling.
    • Global middlewares for request management.
    • Guards for permission management.
    • Interceptors for request management.
  • A shared module for services shared between modules.
    • Utilities
    • Shared business logic
  • Use the standard Jest framework for testing.
  • Write tests for each controller and service.
  • Write end to end tests for each api module.
  • Add a admin/test method to each controller as a smoke test.
在审查或编写代码时，请遵循以下准则：
  • 使用模块化架构
  • 将API封装在模块中
    • 每个主领域/路由对应一个模块
    • 每个路由对应一个控制器
    • 次要路由对应其他控制器
    • 包含存放数据类型的models文件夹
    • 使用class-validator验证输入DTO
    • 为输出声明简单类型
    • 包含存放业务逻辑和持久化代码的services模块
    • 每个实体对应一个服务
  • 为Nest工件创建核心模块
    • 使用全局过滤器处理异常
    • 使用全局中间件管理请求
    • 使用守卫进行权限管理
    • 使用拦截器管理请求
  • 创建供各模块共享的shared模块
    • 工具类
    • 共享业务逻辑
  • 使用标准Jest框架进行测试
  • 为每个控制器和服务编写测试
  • 为每个API模块编写端到端测试
  • 为每个控制器添加一个admin/test方法作为冒烟测试

Memory Protocol (MANDATORY)

内存协议（强制性）

Before starting:
bash
cat .claude/context/memory/learnings.md
After completing: Record any new patterns or exceptions discovered.
ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
开始前：
bash
cat .claude/context/memory/learnings.md
完成后： 记录任何新发现的模式或例外情况。
假设中断：你的上下文可能会重置。如果未存储在内存中，就视为未发生过。
