angular-hexagonal

Angular hexagonal architecture structures features into four layers: Domain, Application, Infrastructure, and Presentation. This organizes domain models, repository ports, use cases, DTOs, mappers, and UI state to ensure clean separation of concerns.

Domain ports and use cases in Angular hexagonal architecture define explicit contracts for repository interactions and application logic. This mechanism isolates core domain models from infrastructure dependencies like API clients, enabling better testability and maintainability.

Yes, hexagonal architecture separates API clients from UI components by placing infrastructure logic in the Infrastructure layer and UI state in the Presentation layer. This ensures domain ports and mappers handle data flow without coupling external dependencies.

DTOs and mappers in Angular layered architecture belong to the Application and Infrastructure layers. Mappers transform data between API DTOs and domain models, keeping the Domain layer pure and free from external data formats.

Apply domain-driven design to an Angular module when you need scalable collaboration across teams and consistent feature scoping. It is ideal for complex applications requiring immutable interfaces, pure functions, and strict separation of domain logic from infrastructure.
