clean-architecture

To isolate domain logic, enforce clean architecture boundaries by separating inner domain entities and use cases from outer infrastructure layers, ensuring dependencies always point inward toward the domain.

Structuring with clean architecture boundaries isolates domain logic from frameworks, defining domain ports and outer adapters wired via dependency injection to achieve high testability and maintainability.

Apply dependency inversion by defining domain ports as interfaces, implementing outer adapters for infrastructure, and wiring them together using dependency injection to invert dependency flow inward during refactors.

You need clean architecture boundaries during feature design and refactors when isolating core business logic from frameworks and infrastructure is required to improve testability and maintainability across modules.

Yes, clean architecture requires dependency injection to compose the architecture by wiring outer infrastructure adapters into inner domain ports, ensuring dependencies point inward and domain logic remains isolated.

Enforcing strict clean architecture boundaries requires significant boilerplate to define ports and adapters, increasing initial complexity for simple features where isolating domain logic from infrastructure provides minimal value.
