Most browsers don't support the pushsubscriptionchange event.
We workaround this by saving the current push subscription in IndexedDB so we can check during every page load if the push subscription changed.
If that is the case, we manually sync the push subscription with the server.
However, this solution is not perfect as mentioned in https://medium.com/@madridserginho/how-to-handle-webpush-api-pushsubscriptionchange-event-in-modern-browsers-6e47840d756f which was used for reference:
> This solution is not perfect, the user could lose some push notifications if he doesn’t open the webapp for a long time.

* npm uninstall next-pwa
next-pwa was last updated in August 2022.
There is also an issue which mentions that next-pwa is abandoned (?): https://github.com/shadowwalker/next-pwa/issues/482
But the main reason for me uninstalling it is that it adds a lot of preconfigured stuff which is not necessary for us.
It even lead to a bug since pages were cached without our knowledge.
So I will go with a different PWA approach. This different approach should do the following:
- make it more transparent what the service worker is doing
- gives us more control to configure the service worker and thus making it easier
* Use workbox-webpack-plugin
Every other plugin (`next-offline`, `next-workbox-webpack-plugin`, `next-with-workbox`, ...) added unnecessary configuration which felt contrary to how PWAs should be built.
(PWAs should progressivly enhance the website in small steps, see https://web.dev/learn/pwa/getting-started/#focus-on-a-feature)
These default configurations even lead to worse UX since they made invalid assumptions about stacker.news:
We _do not_ want to cache our start url and we _do not_ want to cache anything unless explicitly told to.
Almost every page on SN should be fresh for the best UX.
To achieve this, by default, the service worker falls back to the network (as if the service worker wasn't there).
Therefore, this should be the simplest configuration with a valid precache and cache busting support.
In the future, we can try to use prefetching to improve performance of navigation requests.
* Add support for Web Share Target API
See https://developer.chrome.com/articles/web-share-target/
* Use Web Push API for push notifications
I followed this (very good!) guide: https://web.dev/notifications/
* Refactor code related to Web Push
* Send push notification to users on events
* Merge notifications
* Send notification to author of every parent recursively
* Remove unused userId param in savePushSubscription
As it should be, the user id is retrieved from the authenticated user in the backend.
* Resubscribe user if push subscription changed
* Update old subscription if oldEndpoint was given
* Allow users to unsubscribe
* Use LTREE operator instead of recursive query
* Always show checkbox for push notifications
* Justify checkbox to end
* Update title of first push notification
* Fix warning from uncontrolled to controlled
* Add comment about Notification.requestPermission
* Fix timestamp
* Catch error on push subscription toggle
* Wrap function bodies in try/catch
* Use Promise.allSettled
* Filter subscriptions by user notification settings
* Fix user notification filter
* Use skipWaiting
