Note: This feature is available in Web Workers.
The delete() method of the ContentIndex interface unregisters an item from the currently indexed content.
Note: Calling delete() only affects the index. It does not delete anything from the Cache.
delete(id)idThe unique identifier of the indexed content you want the ContentIndex object to remove.
Returns a Promise that resolves with undefined.
No exceptions are thrown.
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");
