architecture-patterns

You structure backend systems by applying Clean Architecture, Hexagonal Architecture, and DDD patterns to enforce clear boundaries. This establishes domain models, ports/adapters, and bounded contexts to decouple core logic from infrastructure for maintainable codebases.

Hexagonal Architecture separates concerns by using ports and adapters to isolate domain logic from infrastructure. This enables flexible architectures that allow easy testing, component substitution, and scalable maintenance for both microservices and monoliths.

You need bounded contexts and repository patterns when decoupling core domain logic from infrastructure in backend APIs. They establish clear boundaries and testability, enabling scalable maintenance and easy substitution of components across services.

Yes, you can apply these architecture patterns across new projects or refactors. Structuring domains, ports, adapters, and infrastructure layers allows you to establish clear separation of concerns and testability in existing monolithic applications.

Structure directories by separating domain models, use cases, controllers/adapters, and infrastructure layers. Applying DDD patterns with recommended directory layouts ensures clear boundaries and decouples core logic from external infrastructure concerns.

Clean Architecture improves testability and maintainability by enforcing domain models and layered structures that decouple core logic from infrastructure. This allows easy substitution of components and flexible architecture for scalable backend services.
