title: What's the best approach to allow 2 user's browsers to communicate to each other
body: <p>I want to make an browser based chess game. Where 2 users take turns making moves on the same board.</p>
  
  <p>At the moment I've set in motion a tomcat server with spring that picks up rest calls made by the node server.</p>
  
  <p>However I'm making a rest call every time any user makes a move. Although the response happens very quickly as there is very little to be done on the server side. </p>
  
  <p>But I feel this may not be the best approach. Is there a better alternative or would rest calls be sufficient in this scenario?</p>
