Great article. It helped me finally understand serviceWorkers.

After some more digging I started to wonder if it wouldn't be better to avoid storing ServiceWorkerRegistration and retrieve one when needed.
Should I concern that object can "expire" after some longer time?

I came to this:

if ('serviceWorker' in navigator) {
    navigator.serviceWorker.ready.then(registration => {
        const registrationWaiting = serviceWorkerRegistration?.waiting;
        ...
    });
}

Well yeah, when user doesn't click the Update button then maybe should think about the "expiring". Should test it out. Retriving it when needed probably would be safer solution?

I will use your example for now and will see in future if there are any issues with it. If yes I will come back to report it :)
