Hypermedia As The Engine Of Application State (HATEOAS) is a constraint of the REST application architecture.

The principle of HATEOAS is that a client interacts with a network application entirely through hypermedia provided dynamically by application servers. A REST client needs no prior knowledge about how to interact with any particular application or server beyond a generic understanding of hypermedia.

Is REST and HATEOAS a good architecture for web services?

If I understand correctly, REST was formalized by Roy Fielding as a descriptive model of the architecture of the web. AFAIK Fielding didn't claim REST was any good, he was just describing the de-facto architecture of the web. The web had already at…
