RAML
RAML (RESTful API Modeling Language) is a YAML-based language for describing RESTful APIs, providing a human-readable format to define endpoints, methods, parameters, responses, and other API details. It enables developers to design, document, and test APIs before implementation, promoting consistency and collaboration across teams. RAML supports code generation, validation, and integration with tools like API gateways and testing frameworks.
Developers should learn RAML when building or maintaining RESTful APIs, as it streamlines the design process, reduces errors through early validation, and improves documentation quality. It is particularly useful in microservices architectures, API-first development approaches, and projects requiring clear API specifications for frontend-backend coordination or third-party integrations.
