title: Server sent event vs web sockets?
body: <p>I'm working on a web app that is accessible to users via multiple platforms from smartphones to desktops which needs to sometimes make a communication between two clients for example if I want my friend to join my network I'd send him a friend request but I want that request to be seen by my friend without him having to refresh the page.</p>
  
  <p>In this scenario which would be a better choice? 
  And also since I want this to work on as many platforms and browsers as possible which has more browser support?
  Is there a better option?</p>
