✓ 应当这么做
- ✓ Keep controllers thin: transport concerns only, business logic in providers
- ✓ Register DTO validation pipes globally and declare the response shape explicitly
- ✓ Emit internal events through the module event bus instead of direct cross-module calls
✕ 常见反模式
- ✕ Circular module imports patched with forwardRef
- ✕ Services that both query the database and format the HTTP response
- ✕ Guards duplicated per route when they belong at controller level
◎ 交付前验证
- ◎ e2e tests hit the real HTTP surface
- ◎ DI graph builds without circular dependency warnings
- ◎ Swagger/OpenAPI output regenerated for changed DTOs
