  if (!(self.Notification && self.Notification.permission === 'granted')) {
    return;
  }
  var data = {};
  if (event.data) {
    data = event.data.json();
  }
  var title = data.title || "Something Has Happened";
  var message = data.message || "Here's something you might want to check out.";
  var icon = "images/new-notification.png";
  var notification = new Notification(title, {
    body: message,
    tag: 'simple-push-demo-notification',
    icon: icon
  });
  notification.addEventListener('click', function() {
    if (clients.openWindow) {
