Get HATEOAS and Hypermedia right with Spring
summary
Practical walkthrough of adding hypermedia to an existing API using Spring HATEOAS and Spring Data REST with a live GitHub example: root discoverability returns HAL links, OPTIONS reveals allowed verbs, GET on a book includes a self and add-to-cart link, POST adds a book to a cart and PATCH sets purchased=true to produce a receipt URL. Shows mapping to controller methods (no hardcoded URIs), uses HAL as the hypermedia type, and demonstrates Jackson JSON views and field filtering to cut a 40‑field book payload.
