A PeriodicSyncManager object.
You can access the property from either your main script or the registered service worker.
Here is an example from the main script:
js
// reference registration const registration = await navigator.serviceWorker.ready; // feature detection if ("periodicSync" in registration) { // Background Periodic Sync functionality const periodicSync = registration.periodicSync; }
From the service worker:
js
// service worker script const periodicSync = self.registration.periodicSync;
