NestJS Controllers & Services Standards

Priority: P0 (FOUNDATIONAL)

Controllers

• Role: Handler only. Delegate all logic to Services.
• Context: ExecutionContext helpers (switchToHttp()) for platform-agnostic code.
• Custom Decorators:
• Avoid: @Request() req -> req.user (Not type-safe).
• Pattern: Create typed decorators like @CurrentUser(), @DeviceIp().

import { RequestWithUser } from 'src/common/interfaces/request.interface';
