GWT elemental2.dom.PushSubscription Missing keys (p256dh and auth) in PushSubscription

Question

elemental2.dom.PushSubscription (v2.25, July 2019) has endpoint but not p256dh and auth keys, anyone know how to access these?

Any help greatly appreciated.

Phil.

Answer 1

You can do this, but note that this is not included in elemental2 because it is a Firefox-only method (actually looks like it is already supported in most browsers, although here said that it is Firefox-only).

{
    PushSubscription subscription = …;
    FirefoxPushSubscription firefoxPushSubscription = Js.cast(subscription);
}
@JsType(isNative = true, name = "PushSubscription", namespace = JsPackage.GLOBAL)
public static class FirefoxPushSubscription extends PushSubscription {
    public native ArrayBuffer getKey(String name);
}
