StorageAccessHandle: caches property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The caches property of the StorageAccessHandle interface returns an unpartitioned CacheStorage object if access was granted, and throws a SecurityError DOMException otherwise.

Value

A CacheStorage object.

Examples

document.requestStorageAccess({ caches: true }).then(
  (handle) => {
    console.log("caches access granted");
    const cache = await handle.caches.open("foo");
    await cache.add("/");
  },
  () => {
    console.log("caches access denied");
  },
);

Note: See Using the Storage Access API for a more complete example.
