The delete() method of the Cache interface finds the Cache entry whose key is the request, and if found, deletes the Cache entry and returns a Promise that resolves to true. If no Cache entry is found, it resolves to false.
delete(request)
delete(request, options)
request
The Request you are looking to delete. This can be a Request object or a URL.
options Optional
An object whose properties control how matching is done in the delete operation. The available options are:
ignoreSearch
A boolean value that specifies whether the matching process should ignore the query string in the URL. If set to true, the ?value=bar part of http://foo.com/?value=bar would be ignored when performing a match. It defaults to false.
ignoreMethod
A boolean value that, when set to true, prevents matching operations from validating the Request HTTP method (normally only GET and HEAD are allowed.) It defaults to false.
ignoreVary
A boolean value that, when set to true, tells the matching operation not to perform VARY header matching. In other words, if the URL matches you will get a match regardless of whether the Response object has a VARY header. It defaults to false.
cacheName
A string that represents a specific cache to search within. Note that this option is ignored by Cache.delete().
a Promise that resolves to true if the cache entry is deleted, or false otherwise.
caches.open("v1").then((cache) => {
cache.delete("/images/image.png").then((response) => {
someUIUpdateFunction();
});
