Это экспериментальная технология
Так как спецификация этой технологии ещё не стабилизировалась, смотрите таблицу совместимости по поводу использования в различных браузерах. Также заметьте, что синтаксис и поведение экспериментальной технологии может измениться в будущих версиях браузеров, вслед за изменениями спецификации.

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 has replaced functionality offered by the obsolete PushRegistrationManager.

Properties

None

Methods

PushManager.subscribe()
Subscribes to a push service. It Returns a promise that resolves to a PushSubscription object containing details of a new push subscription.
PushManager.getSubscription()
Retrieves an existing push subscription. It Returns a promise that resolves to a PushSubscription object containing details of the existing subscription.
PushManager.permissionState()
Returns a Promise that resolves to the permission state of the current PushManager, which will be one of 'granted', 'denied', or 'default'.

Deprecated methods

PushManager.hasPermission()
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().
PushManager.register()
Subscribes to a push subscription. Replaced by PushManager.subscribe().
PushManager.registrations()
Retrieves existing push subscriptions. Replaced by PushManager.getSubscription().
PushManager.unregister()
Unregisters and deletes a specified subscription endpoint. In the updated API, a subscription is can be unregistered via the PushSubscription.unsubscribe() method.

Example

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

navigator.serviceWorker.register('serviceworker.js').then(
  function(serviceWorkerRegistration) {
    serviceWorkerRegistration.pushManager.subscribe().then(
      function(pushSubscription) {
        console.log(pushSubscription.subscriptionId);
        console.log(pushSubscription.endpoint);
        // 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.
        console.log(error);
      }
    );
  });
