[question]: Missing addObserver function

[xylish7]

How can we help?

In docs it is mentioned that if you want to listen for push subscription changes, addObserver listener should be used.

However it looks like there is no addObserver function so I'm not sure how I can listen to notification changes.

Thank you!

Hi @xylish7,

Thank you for reporting this issue with our documentation, that we will fix.

The most updated listing of available methods is available in the migration guide here.

The correct method is addEventListener("change", listener) with this example:

    const listener = (event: PushSubscriptionChangedState) => {
        console.log("Push subscription changed: " + (event));
    };
    OneSignal.User.pushSubscription.addEventListener("change", listener);
    // Remove the listener
    OneSignal.User.pushSubscription.removeEventListener("change", listener);

I apologize for the confusion and will update our docs.

I see and no problem😊. Will try with OneSignal.User.pushSubscription.addEventListener("change", listener); . Thank you for your response.
