HATEOAS Principles for REST

HATEOAS stands for Hypermedia as the Engine of Application State. It's a core constraint of RESTful architecture that suggests an API should guide clients through available actions using hypermedia links.

Think of it like a website: you navigate by clicking links, not by typing URLs from memory. HATEOAS brings this same idea to APIs.

HATEOAS makes your API more discoverable and evolvable. Instead of hardcoding URLs, clients discover available actions directly from the API's responses.

• Client Independence: Clients don't need to know URL structures beforehand.
• API Evolution: You can change URL paths without breaking clients, as long as the link relation names ("rel") remain consistent.
• Self-Documentation: Responses inherently describe what actions can be taken next.
