To scaffold a NestJS module, you generate the associated .module.ts, .controller.ts, and .service.ts files alongside Data Transfer Objects. This structure enforces modular architecture and dependency injection for enterprise-grade TypeScript backend applications.

The best way to implement JWT authentication in a NestJS REST API is by using Passport integration with custom guards. This approach secures endpoints by validating tokens and restricting access to authorized users within your controllers.

Yes, you can integrate TypeORM or Prisma into a NestJS backend. This skill configures database connections within your modules, enabling robust data persistence and ORM-driven query execution for your enterprise services.

You add Swagger documentation to NestJS API endpoints by configuring the integration within your application. This automatically generates API schemas from your controllers and DTOs, providing interactive documentation for your REST services.

Yes, NestJS supports interceptors and pipes for request validation and data transformation. Pipes validate payload DTOs before reaching controllers, while interceptors wrap requests to apply extra logic like logging or response mapping.

You structure a secure NestJS microservice by applying modular design and dependency injection across your modules. Implementing guards, interceptors, and validation pipes ensures the backend architecture remains scalable and maintainable.
