clean-architecture

To enforce layered architecture and prevent architectural erosion, decompose your project into Domain, Application, and Infrastructure layers with strict inward-only dependencies. This separation ensures concerns do not leak across boundaries during restructuring or new module creation.

The dependency rule in clean architecture requires inward-only dependencies to maintain domain purity. This means Application and Infrastructure layers depend on the Domain layer, but the Domain layer never depends outward, ensuring business logic remains isolated from infrastructure concerns.

To apply dependency inversion when creating new modules, use ports and interfaces so that inner layers define contracts while outer infrastructure layers implement them. This enforces strict layering and isolates domain logic from specific infrastructure implementations.

You need to restructure an existing codebase into Domain, Application, and Infrastructure layers when applying clean architecture to prevent architectural erosion. This is necessary when refactoring for maintainability or documenting architecture to align with strict dependency rules.

Yes, clean architecture works with domain-driven design for software design layering by aligning Domain, Application, and Infrastructure layers with DDD concepts. This combination enforces domain purity and uses ports and interfaces for dependency inversion to isolate business logic.

Applying strict layered architecture to an existing project requires clear dependency rules, domain purity, and dedicated layers, which may demand significant refactoring effort. The process enforces inward-only dependencies, potentially impacting existing infrastructure coupling during restructuring.
