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

js
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.
js
caches.open("v1").then((cache) => { cache.delete("/images/image.png").then((response) => { someUIUpdateFunction(); }); });
