Functional Hexagonal Architecture
Implements hexagonal architecture patterns with a pure functional core and side-effect shell to build maintainable, testable applications.
This skill provides a comprehensive framework for structuring software using functional programming principles and the ports-and-adapters pattern. It guides developers in isolating side effects—such as database access, API calls, and file I/O—to the 'shell' of the application while keeping business logic within a 'pure core.' By utilizing function-based dependency injection and pipeline composition, this skill helps create modular codebases that are easy to test without mocks, highly scalable, and structurally resilient to changes in external infrastructure.
