Examples
Below is an asynchronous function, that removes an item from the content index. We receive a reference to the current
ServiceWorkerRegistration, which allows us to access the
index property and thus access the
delete method.
async function unregisterContent(article) {
// reference registration
const registration = await navigator.serviceWorker.ready;
// feature detect Content Index
if (!registration.index) return;
// unregister content from index
await registration.index.delete(article.id);
}
The delete method can also be used within the
service worker scope.
self.registration.index.delete("my-id");
