ContentIndex.delete()

Draft: This page is not complete.

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.

Syntax

ContentIndex.delete(id).then(...);

Parameters

This method receives no parameters.

Return value

Returns a Promise that resolves with undefined

Exceptions

No exceptions are thrown.

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');
