The periodicSync
read-only property of the ServiceWorkerRegistration
interface returns a reference to the PeriodicSyncManager
interface, which allows for registering of tasks to run at specific intervals.
ServiceWorkerRegistration.periodicSync
Value

object.
Examples
You can access the property from either your main script or the registered service worker.
Here is an example from the main script:
// 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:
// service worker script const periodicSync = self.registration.periodicSync;
