Periodic background synchronization
In background syncing, we register synchronization tasks that trigger the service worker’s sync event whenever we have connectivity again.
Periodic background synchronization refers to getting data regularly from the server (even if the application is closed) to ensure that the application stays up-to-date with the latest information. It’s especially beneficial when the data on the backend changes frequently.
