The applicationServerKey
read-only property of the PushSubscriptionOptions
interface contains the public key used by the push server.
A public key your push server uses to send messages to client apps via a push server. This value is part of a signing key pair generated by your application server, and usable with elliptic curve digital signature (ECDSA), over the P-256 curve. If no applicationServerKey
member is passed when initialized, it will be set to null
.
In the example below the value of applicationServerKey
is printed to the console.
js
navigator.serviceWorker.ready.then((reg) => { reg.pushManager.getSubscription().then((subscription) => { const options = subscription.options; console.log(options.applicationServerKey); // the public key }); });
