match method

JSPromise<Response?> match(
  1. RequestInfo request, [
  2. MultiCacheQueryOptions options
])

The match() method of the CacheStorage interface checks if a given Request or URL string is a key for a stored Response. This method returns a Promise for a Response, or a Promise which resolves to undefined if no match is found.

You can access CacheStorage through the global caches property.

Cache objects are searched in creation order.

Note: CacheStorage.match is a convenience method. Equivalent functionality is to call cache.match on each cache (in the order returned by CacheStorage.keys) until a Response is returned.

Implementation

external JSPromise<Response?> match(
  RequestInfo request, [
  MultiCacheQueryOptions options,
]);
