SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides senior-level guidance and ready-to-use patterns for designing, implementing, and testing modular NestJS TypeScript backends so teams can deliver reliable APIs with consistent architecture and best practices.

Core Features & Use Cases

  • Modular Architecture & DI: Design modules, providers, and dependency injection patterns for scalable services.
  • DTOs & Validation: Create request/response DTOs with class-validator and class-transformer for strong input validation.
  • Auth & Security: Implement JWT/Passport authentication, guards, and secure error handling.
  • Database & Testing: Integrate TypeORM or Prisma and provide unit and E2E testing patterns with Jest and Supertest.
  • Use Case: Scaffold a users module with controller, service, DTOs, database model, authentication, Swagger docs, and unit tests for a production-ready API endpoint.

Quick Start

Use the nestjs-expert skill to generate a modular NestJS module with controller, service, DTOs, Swagger decorators, and basic unit tests for a "users" feature.

Does this NestJS guidance support both TypeORM and Prisma for database integration?▼

Yes, this NestJS guidance supports both TypeORM and Prisma, providing patterns to integrate either ORM for database setup, model creation, and repository injection within your modules.

How do I write unit and E2E tests for a NestJS module using Jest and Supertest?▼

Write unit and E2E tests for your NestJS module by using Jest to mock services and Supertest to simulate HTTP requests, ensuring your controllers, services, and API endpoints function correctly.

Can I generate Swagger documentation automatically for my NestJS REST API endpoints?▼

Yes, you can generate Swagger documentation for your NestJS REST API by applying Swagger decorators to your controllers and DTOs, producing interactive API docs for your endpoints.
