Navigator: serviceWorker property

{{securecontext_header}}{{APIRef("Service Workers API")}}

The feature may not be available in private mode.

Note that a worker can similarly access the {{domxref("ServiceWorkerContainer")}} for a document using {{domxref("WorkerNavigator.serviceWorker")}}.

Value

{{domxref("ServiceWorkerContainer")}}.
