The get() method of the BackgroundFetchManager interface returns a Promise that resolves with the BackgroundFetchRegistration associated with the provided id or undefined if the id is not found.

get(id)

id: The ID of a BackgroundFetchRegistration defined by calling fetch().

The following examples shows how to use get() to retrieve a BackgroundFetchRegistration. With an active service worker, use the ServiceWorkerRegistration.backgroundFetch to access the BackgroundFetchManager object and call its get() method.

navigator.serviceWorker.ready.then(async (swReg) => {
  const bgFetch = await swReg.backgroundFetch.get("my-fetch");
});
// my code block
