clean-ddd-hexagonal

Structure your backend by defining clear domain boundaries across Domain, Application, and Infrastructure layers, using ports and adapters to separate concerns and ensure testability. This approach creates modular, maintainable systems.

Hexagonal architecture uses ports and adapters to isolate infrastructure dependencies, while clean architecture enforces layered dependency inversion. This blueprint combines both patterns to define clear domain boundaries and enable easy infrastructure replacement.

Implement CQRS and Event Sourcing by defining domain events for cross-boundary communication and using repositories within the application layer. This blueprint provides guidance and references for integrating these patterns alongside tactical DDD concepts.

Use DDD and hexagonal architecture for multi-layer projects needing clear boundaries, testability, and maintainable domain models across APIs, services, and infrastructure. It suits complex systems requiring easy infrastructure replacement and cross-boundary communication.

Define ports and adapters by aligning domain and application boundaries, ensuring infrastructure components interact through defined interfaces. This blueprint provides references and examples showing entities, value objects, repositories, and domain events.

Yes, the blueprint includes references and guidance for strategic and tactical patterns like DDD, hexagonal architecture, and ACL to accelerate architecture decisions, making it accessible while requiring alignment of domain and application boundaries.
