title: REST API-Centric application, with web sockets, using node.js?
body: <p>I never done any API, I just recently become aware of REST, never used sockets or node.js, but I have this simple project in mind using all of these.</p>
  
  <p>Imagine usual app with request/response stuff. Nothing fancy. But then sometimes I need real time functionality, lets say there's a live support for website, a chat. So majority of users never need sockets and everything is easy, but when they do, what's then? How that would look and work with restful api? </p>
