REST. Express.js

REST services became a de-facto standard of data exchange for public APIs. Twitter, GitHub, Parse are just few examples that rely on REST to exchange data with the clients. Before we start to write our first REST service with Node, let's see what exactly is REST and how it works. REST stands for 'REpresentational State Transfer'. It leverages the semantics of HTTP protocol to express operations over a some collection of items (data). REST typically uses JSON to send and receive data. NOTE: This is a common misconception to call every HTTP-based JSON service REST.
