What is REST? A Comprehensive Guide for Software Developers
Did you know that the architectural style guiding how most modern web APIs work was conceived in a PhD dissertation? This surprising fact sets the stage for our exploration of REST, a fundamental concept in web development that's both elegant and powerful. 1. The Birth of REST REST, or Representational State Transfer, emerged from the mind of Roy Fielding in his 2000 PhD dissertation . It's not just a set of rules, but a philosophical approach to building scalable, efficient web services. 2. Decoding REST At its core, REST is about simplicity and scalability. It's an architectural style that models data as resources, each identified by a unique URL. These resources can be manipulated using a small set of operations, typically corresponding to standard HTTP methods. 3. The Pillars of REST REST isn't just a free-for-all.
