clean-ddd-hexagonal

Structure backend systems using DDD and hexagonal architecture by enforcing clean architecture boundaries across domain models, aggregates, repositories, bounded contexts, and ports and adapters to keep domain logic decoupled from infrastructure.

Implement CQRS and event sourcing in a microservices backend by applying clean architecture boundaries and utilizing the outbox pattern, ensuring domain logic remains pure while managing infrastructure dependencies through defined ports and adapters.

Clean architecture with DDD and hexagonal patterns is language-agnostic and works across Go, Rust, Python, TypeScript, Java, and C#, providing inward-dependency rules and structural guidance regardless of the backend technology stack.

Separate domain logic from infrastructure when designing scalable APIs by defining clear boundaries across Domain, Application, and Infrastructure layers, using the ports and adapters strategy to enable easy testing and component replacement.

Use the outbox pattern with event sourcing in bounded contexts when you need to reliably publish domain events while maintaining strict clean architecture boundaries and inward-dependency rules within your microservices architecture.
