How do I enable background sync in my application?

To enable background sync, you need to use the Background Sync API. First, ensure your app is a Progressive Web App (PWA).

What are the steps to implement the Background Sync API?

You need to register a service worker, then use the SyncManager to schedule sync events. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

self.addEventListener('sync', function(event) {
  if (event.tag == 'mySync') {
    event.waitUntil(doSomeBackgroundSync());
  }
});

This code listens for a sync event and runs the doSomeBackgroundSync function.

What should I do if the sync fails?

If the sync fails, you can handle the error in the catch block of your promise. You might also want to retry the sync later.
