ContentIndex.delete()

Draft
This page is not complete.

The delete() method of the ContentIndex interface unregisters an item from the currently indexed content.

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');
