NotificationEvent: notification property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is only available in Service Workers.

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 deferred use in the notificationclick event.

Value

A Notification object.

Examples

js
self.addEventListener("notificationclick", (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((clientList) => {
        for (const client of clientList) {
          if (client.url === "/" && "focus" in client) return client.focus();
        }
        if (clients.openWindow) return clients.openWindow("/");
      }),
  );
});
