What architecture does this skill follow?

It follows Domain-Driven Design (DDD) and Clean Architecture principles, specifically focusing on the Application Layer to separate business orchestration from infrastructure and HTTP concerns.

What kind of validation does it provide?

The generated use cases include dedicated validation methods and input/output interfaces to ensure data integrity before any business logic is executed.

Can I use it for event-driven systems?

Absolutely. The skill includes specific patterns for generating event listeners and ensuring that use cases emit domain events to the event bus after successful operations.

Does it handle dependency injection?

Yes, it automatically applies tsyringe decorators and follows specific rules for injecting repositories by string tokens and other use cases by class.

API Development

Generates domain-driven application layer use cases and event listeners with automated dependency injection and orchestration logic.

The DDD UseCase Generator streamlines the creation of application layer components within Domain-Driven Design architectures. It automates the generation of single-responsibility use case classes and event listeners, ensuring consistent patterns for dependency injection via tsyringe, domain event emission, and input validation. By separating orchestration logic from infrastructure concerns, this skill helps developers implement complex business workflows and event-driven triggers while maintaining clean architecture boundaries and robust error handling.
