Critical Patterns

Module Organization (REQUIRED)

// ✅ ALWAYS: Feature modules with clear boundaries
@Module({
  imports: [TypeOrmModule.forFeature([User])],
  controllers: [UsersController],
  providers: [UsersService],
  exports: [UsersService],
})
export class UsersModule {}

DTOs with Validation (REQUIRED)

// ✅ ALWAYS: Use class-validator decorators
