architecture-patterns

Hexagonal architecture isolates core business logic from external technologies using ports and adapters. This pattern makes your application's central domain completely technology-agnostic, allowing you to swap out databases or UI layers without modifying core logic.

Yes, you can apply these architecture patterns when refactoring a monolithic backend. The Skill provides implementation guidance to break down monoliths into modular structures using Clean Architecture, ensuring a more maintainable and testable foundation.

If your backend domain logic is tightly coupled to frameworks or databases, Hexagonal Architecture decouples it using ports and adapters. This allows you to define clear boundaries, ensuring your core use cases remain independent of external infrastructure changes.

Your backend lacks testability because core logic is likely mixed with infrastructure code. Applying Clean Architecture separates these concerns into distinct layers, allowing you to unit test domain rules independently of databases or web frameworks.
