What are the advantages of hexagonal architecture in software development?

Hexagonal architecture, also known as the Ports and Adapters pattern, offers several advantages, including improved testability, separation of concerns, and easier integration with external systems.

Can you explain how it improves testability?

Certainly! Hexagonal architecture allows you to isolate the core logic of your application from external dependencies, making it easier to write unit tests for the core functionality without needing to mock external systems.

What about separation of concerns?

Separation of concerns is achieved by organizing the application into distinct layers. This means that the business logic, user interface, and external services are decoupled, which enhances maintainability and scalability.

Are there any downsides to using hexagonal architecture?

While hexagonal architecture has many benefits, it can introduce complexity, especially for smaller projects. The initial setup may require more effort compared to simpler architectures.
