NotificationEvent.notification

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The notification read-only property of the NotificationEvent interface returns the instance of the Notification that was clicked to fire the event. The Notification provides read-only access to many properties that were set at the instantiation time of the Notification such as tag and data attributes that allow you to store information for defered use in the notificationclick event.

Returns

A Notification object.

Example

self.addEventListener('notificationclick', function(event) {
  console.log('On notification click');

  // Data can be attached to the notification so that you
  // can process it in the notificationclick handler.
  console.log('Notification Tag:', event.notification.tag);
  console.log('Notification Data:', event.notification.data);
  event.notification.close();

  // This looks to see if the current is already open and
  // focuses if it is
  event.waitUntil(clients.matchAll({
    type: "window"
  }).then(function(clientList) {
    for (var i = 0; i < clientList.length; i++) {
      var client = clientList[i];
      if (client.url == '/' && 'focus' in client)
        return client.focus();
    }
    if (clients.openWindow)
      return clients.openWindow('/');
  }));
});
