What problem does it solve?
This Skill provides a comprehensive guide for developing NestJS applications, ensuring adherence to best practices for architecture, dependency injection, and module organization. It helps developers build scalable, maintainable, and high-quality backend services, reducing technical debt and improving team collaboration.
Core Features & Use Cases
- Domain-Centric Modularization: Guides on organizing modules by business domain, not by technical function.
- Dependency Injection: Enforces constructor injection and proper provider registration for testability and clarity.
- DTO/Entity Separation: Ensures clear boundaries between data transfer objects and database entities, preventing logic leakage.
- Error Handling: Advocates for domain-specific exception filters and explicit error throwing for robust API responses.
- Use Case: A backend developer is starting a new NestJS project and needs to establish a solid architectural foundation.
- Use Case: An existing NestJS application has grown complex, and the team needs guidelines to refactor it for better maintainability and scalability.
