This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The PushManager interface of the Push API provides a way to receive notifications from third-party servers as well as request URLs for push notifications.

This interface is accessed via the ServiceWorkerRegistration.pushManager property.

Note: This interface replaces functionality previously offered by the obsolete PushRegistrationManager interface.




Retrieves an existing push subscription. It returns a Promise that resolves to a PushSubscription object containing details of an existing subscription. If no existing subscription exists, this resolves to a null value.
Returns a Promise that resolves to the permission state of the current PushManager, which will be one of 'granted', 'denied', or 'prompt'.
Subscribes to a push service. It returns a Promise that resolves to a PushSubscription object containing details of a push subscription. A new push subscription is created if the current service worker does not have an existing subscription.

Deprecated methods

Returns a Promise that resolves to the PushPermissionStatus of the requesting webapp, which will be one of granted, denied, or default. Replaced by PushManager.permissionState().
Subscribes to a push subscription. Replaced by PushManager.subscribe().
Retrieves existing push subscriptions. Replaced by PushManager.getSubscription().
Unregisters and deletes a specified subscription endpoint. In the updated API, a subscription is unregistered by calling the PushSubscription.unsubscribe() method.


this.onpush = function(event) {
  // From here we can write the data to IndexedDB, send it to any open
  // windows, display a notification, etc.

  function(serviceWorkerRegistration) {
      function(pushSubscription) {
        // The push subscription details needed by the application
        // server are now available, and can be sent to it using,
        // for example, an XMLHttpRequest.
      }, function(error) {
        // During development it often helps to log errors to the
        // console. In a production environment it might make sense to
        // also report information about errors back to the
        // application server.
