hexagonal-architecture

To refactor a legacy monolith using hexagonal architecture, you separate business logic from external concerns by defining ports and adapters, creating clear domain boundaries and enabling dependency inversion for better maintainability.

The best way to separate domain logic from external concerns is applying hexagonal architecture, which uses ports and adapters to isolate business rules, ensuring long-term code quality and making use-case orchestration highly testable.

Yes, hexagonal architecture works with TypeScript, Java, Kotlin, and Go. Implementation guidelines are provided for these languages, allowing you to establish clear domain boundaries and dependency inversion across various technology stacks.

To structure a project for ports and adapters implementation, refer to the suggested module layout guidelines, which provide directions on organizing your system to separate business logic from external dependencies effectively.

You need hexagonal architecture for complex systems requiring long-term maintainability and testability. It is particularly suitable when refactoring legacy monolithic applications into systems with clear domain boundaries and dependency inversion.

You use domain-driven design with hexagonal architecture to establish clear domain boundaries because it decouples business logic from external concerns, addressing the challenge of maintaining long-term code quality through effective dependency management.
