clean-architecture

Resolve circular dependencies in a layered architecture by applying the Dependency Rule and dependency inversion. This ensures dependencies point strictly inward toward the domain, preventing external framework leakage and untangling cyclic structural references.

The best way to structure code for maintainability is using a layered architecture that isolates business rules. Separating domain logic from external concerns creates adaptable, testable systems that are easy to understand and maintain over time.

Enforce the Dependency Rule when designing a new service by establishing clear architectural boundaries between layers. Ensure dependencies flow strictly inward from Frameworks to Interface Adapters to Use Cases to Entities, preventing infrastructure code from leaking into the domain.

Yes, Clean Architecture resolves framework leakage by isolating domain logic within inner layers. It enforces strict dependency boundaries, ensuring external frameworks and databases remain in the outer layers and do not contaminate core business logic.

You should not use a layered architecture for simple systems where strict boundary enforcement adds unnecessary complexity. If separating business logic from infrastructure concerns provides no clear maintainability benefit, the overhead of dependency management may be excessive.
