architecture-patterns

You structure a backend using Clean Architecture and Domain-Driven Design by organizing modules around business capabilities to establish clear boundaries. This approach improves maintainability and testability by separating core domain logic from external interfaces.

The best way to refactor a monolith into a scalable backend architecture is to align modules with domain boundaries and apply Hexagonal Architecture. This allows incremental refactoring to establish testable components without disrupting the entire system.

You should use Hexagonal Architecture in backend design when you need to isolate business logic from external concerns like databases or APIs. It establishes clear boundaries and testable components, making it ideal for complex domains requiring high maintainability.

Domain-Driven Design works effectively for building new services from scratch by guiding you to structure code around business capabilities. It provides practical directory layouts and implementation tips to ensure your new service is scalable and testable.

To align backend modules with domain boundaries for incremental refactoring, you initialize your project using the architecture-patterns framework. This provides guided templates and directory layouts to establish clear boundaries and testable components step by step.
