NestJS Patterns

Build enterprise-grade applications with NestJS using modular architecture, dependency injection, and production-ready patterns.

Core Patterns

Module Pattern

@Module({
  imports: [TypeOrmModule.forFeature([User])],
  controllers: [UserController],
  providers: [UserService],
  exports: [UserService],
})
export class UserModule {}

Controller Pattern

@Controller('users')
@UseGuards(JwtAuthGuard)
export class UserController {
  constructor(private readonly userService: UserService) {}

  @Get()
  findAll(): Promise<User[]> {
    return this.userService.findAll();
  }

  @Post()
  create(@Body() createUserDto: CreateUserDto): Promise<User> {
    return this.userService.create(createUserDto);
  }
}

Service Pattern

@Injectable()
export class UserService {
  constructor(
    @InjectRepository(User)
    private userRepository: Repository<User>,
  ) {}

  async findAll(): Promise<User[]> {
    return this.userRepository.find();
  }

  async create(createUserDto: CreateUserDto): Promise<User> {
    const user = this.userRepository.create(createUserDto);
    return this.userRepository.save(user);
  }
}

Best Practices

Use dependency injection
Implement proper error handling
Use DTOs for validation
Implement guards for authentication
Use interceptors for logging
Create custom decorators
Implement microservices patterns
Write comprehensive tests
