clean-architecture

Separate code into Presentation, Application, Domain, and Persistence layers. Coordinate use cases with interfaces and ensure outer layers depend on abstractions, keeping the Domain layer pure and framework-independent to maintain clear boundaries.

Clean architecture organizes software into Presentation, Application, Domain, and Persistence layers, enforcing strict dependency direction. This framework independence ensures maintainable code by isolating business rules from external concerns and improving testability.

Structure new projects into Presentation, Application, Domain, and Persistence layers. Apply explicit dependency rules where outer layers depend on abstractions, ensuring domain purity and framework independence for scalable, testable architecture from the start.

Yes, apply layer boundaries by enforcing dependency direction rules and coordinating use cases with interfaces. Refactor outer layers to depend on abstractions, ensuring domain purity and framework independence across your existing Presentation, Application, Domain, and Persistence structures.

Outer layers depend on abstractions to enforce the Dependency Rule and maintain separation of concerns. This prevents framework coupling, preserves domain purity, and ensures your codebase remains testable and maintainable across all architectural boundaries.

Avoid clean architecture when strict layer boundaries and dependency rules introduce unnecessary overhead for small projects. If framework independence and domain purity are not critical, the added abstraction of coordinating use cases with interfaces may reduce development speed.
