Does this skill work with other frameworks besides NestJS?

While the implementation examples are optimized for NestJS and TypeScript, the core DDD and Clean Architecture principles provided can be adapted to any modern backend framework.

Can I use this for existing legacy projects?

Yes, the skill includes specific strategies for refactoring 'anemic' domain models and tightly-coupled code into a more structured, layered architecture.

What is the main benefit of using Clean Architecture in NestJS?

It ensures business logic is isolated from external frameworks and infrastructure, making the application significantly easier to test, maintain, and adapt to changing requirements over time.

How does this skill help with unit testing?

By enforcing a pure domain layer with no external dependencies, this skill allows you to write high-coverage unit tests that don't require database connections or complex framework mocking.

API開発

Implements Clean Architecture, Domain-Driven Design (DDD), and Hexagonal Architecture patterns for scalable NestJS and TypeScript applications.

This skill empowers developers to build maintainable and testable backend systems by providing structured guidance on Clean Architecture, DDD, and Hexagonal Architecture. It facilitates the creation of rich domain models, clear separation of concerns through concentric architectural layers, and the implementation of independent use cases that encapsulate business logic without direct dependencies on external frameworks like NestJS or TypeORM. Whether you are starting a new enterprise-grade project or refactoring a tightly-coupled MVC system, this skill provides the patterns needed for long-term scalability.
