PushSubscription

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

The PushSubscription interface of the Push API provides a subcription's URL endpoint and allows unsubscription from a push service.

An instance of this interface can be serialized.

Properties

PushSubscription.endpoint Read only: A USVString containing the endpoint associated with the push subscription.
PushSubscription.expirationTime Read only: A DOMHighResTimeStamp of the subscription expiration time associated with the push subscription, if there is one, or null otherwise.
PushSubscription.options Read only: An object containing the options used to create the subscription.
PushSubscription.subscriptionId Read only: A DOMString containing the subscription ID associated with the push subscription.

Methods

PushSubscription.getKey(): Returns an ArrayBuffer which contains the client's public key, which can then be sent to a server and used in encrypting push message data.
PushSubscription.toJSON(): Standard serializer — returns a JSON representation of the subscription properties.
PushSubscription.unsubscribe(): Starts the asynchronous process of unsubscribing from the push service, returning a Promise that resolves to a boolean value when the current subscription is successfully unregistered.

Example

navigator.serviceWorker.ready.then(function(reg) {
  reg.pushManager.getSubscription().then(function(subscription) {
    subscription.unsubscribe().then(function(successful) {
      // You've successfully unsubscribed
    }).catch(function(e) {
      // Unsubscription failed
    })
  })
});
