The BackgroundFetchEvent
interface of the Background Fetch API is the event type for background fetch events dispatched on the service worker global scope.
It is the event type passed to backgroundfetchclick
event and backgroundfetchabort
event.
BackgroundFetchEvent()
Experimental
Creates a new BackgroundFetchEvent
object. This constructor is not typically used, as the browser creates these objects itself and provides them to background fetch event callbacks.
Also inherits properties from its parent, ExtendableEvent
.
BackgroundFetchEvent.registration
Read only Experimental
Returns the BackgroundFetchRegistration
that the event was initialized to.
Also inherits methods from its parent, ExtendableEvent
.
None.
ExamplesIn this example, if the user clicks on the user interface displaying the download progress, a new window will open. The current BackgroundFetchRegistration
is returned by calling event.registration
.
addEventListener("backgroundfetchclick", (event) => {
const bgFetch = event.registration;
if (bgFetch.result === "success") {
clients.openWindow("/latest-podcasts");
} else {
clients.openWindow("/download-progress");
}
});
