keys method

JSPromise<JSArray<Request>> keys([
  1. RequestInfo request,
  2. CacheQueryOptions options
])

The keys() method of the Cache interface returns a Promise that resolves to an array of Request objects representing the keys of the Cache.

The requests are returned in the same order that they were inserted.

Note: Requests with duplicate URLs but different headers can be returned if their responses have the VARY header set on them.

Implementation

external JSPromise<JSArray<Request>> keys([
  RequestInfo request,
  CacheQueryOptions options,
]);
