What are the best practices in hexagonal architecture?

Hexagonal architecture, also known as ports and adapters, emphasizes separation of concerns. Key practices include defining clear boundaries between the core application and external systems, using interfaces for communication, and ensuring that the core logic is independent of frameworks.

Can you explain how to implement these practices?

Certainly! Start by identifying your core domain logic and encapsulating it in a way that it doesn't depend on external frameworks. Use interfaces to define how your application interacts with external systems, and create adapters that implement these interfaces to handle the actual communication.

What are some common pitfalls to avoid?

Common pitfalls include tightly coupling your core logic to specific frameworks, neglecting to define clear interfaces, and failing to test your application in isolation from external dependencies.

How does hexagonal architecture compare to other architectures?

Hexagonal architecture focuses on the application's core and its interactions, making it more adaptable to changes compared to layered architectures, which can lead to tighter coupling between layers.
