clean-architecture

Clean architecture structures software around inward-pointing dependencies across concentric circles—Entities, Use Cases, Interface Adapters, and Frameworks—to protect business rules from external changes. Dependencies point inward, keeping core logic independent of frameworks and databases.

Implement ports and adapters by identifying core entities and use cases, defining interfaces, and wiring adapters together in the plugin-based Main composition root, allowing framework swapping without touching core logic.

Use clean architecture for long-lived projects requiring clear boundaries between layers and high testability. It suits systems needing modular boundaries to evolve and maintain business rules independently from delivery mechanisms.

Yes, clean architecture enforces the dependency rule to align with SOLID principles. It provides guidelines on boundary anatomy, ensuring dependencies point inward toward entities and use cases without circular references.

The limitations of clean architecture include increased initial complexity and boilerplate from strict boundary anatomy and port definitions. Smaller projects might find the overhead of separating Entities, Use Cases, and Interface Adapters unnecessary.
