What problem does it solve?
NestJS provides a powerful framework for building scalable backends, but teams often struggle to enforce modular architecture, consistent dependency injection, and maintainable API design. This Skill guides engineers to structure NestJS projects for enterprise-grade applications by defining module boundaries, DI contracts, security defaults, and clean separation of concerns.
Core Features & Use Cases
- Modular Architecture: Create cohesive modules (e.g., users, auth, payments) that encapsulate controllers, services, and providers.
- Dependency Injection & Testing: Apply DI uniformly, write unit tests and mocks for services, and enable easily replaceable implementations.
- Security, Validation & Documentation: Implement guards, DTO validation, and Swagger/OpenAPI docs for APIs across REST and GraphQL services.
- Data Layer Choices: Integrate with TypeORM or Prisma for database access and repository patterns.
- Operational Excellence: Use Interceptors, Filters, and global pipes for consistent error handling and logging.
Quick Start
Scaffold a NestJS project with modules, controllers, and services, wire up dependency injection, add guards and DTO validation, and enable Swagger documentation to start building a scalable backend.
