title: Push notification facility for mobile web app
body: <p>I have a simple scenario, to receive notification on mobile devices whenever it's generated from Server.</p>
  
  <p>I know this facility is available in native iOS app and Android but I am trying to avoid native path. What I would like that:</p>
  
  <ol>
  <li>A mobile web app which can be access by visiting a URL</li>
  <li>User have ability to create a bookmark on Home screen so that it gets feeling of native app Icon.</li>
  <li>Getting badges of notification(no of messages in round shape)</li>
  <li>Able to receive notification even if browser is closed.</li>
  </ol>
  
  <p>I know there is a possibility of server side events/Web Sockets but can a web app emulate push notification features?</p>
