With this concise book, youβll learn the art of building hypermedia APIs that donβt simply run on the Web, but that actually exist in the Web. Youβll start with the general principles and technologies behind this architectural approach, and then dive hands-on into three fully-functional API examples. Too many APIs rely on concepts rooted in desktop and local area network patterns that donβt scale wellβcostly solutions that are difficult to maintain over time. This book shows system architects and web developers how to design and implement human- and machine-readable web services that remain stable and flexible as they scale.
