Cache: delete() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
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.
Syntax
delete(request)
delete(request, options)
Parameters
request-
The
Requestyou are looking to delete. This can be aRequestobject or a URL. optionsOptional-
An object whose properties control how matching is done in the
deleteoperation. 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=barpart ofhttp://foo.com/?value=barwould be ignored when performing a match. It defaults tofalse. ignoreMethod-
A boolean value that, when set to
true, prevents matching operations from validating theRequestHTTPmethod (normally onlyGETandHEADare allowed.) It defaults tofalse. ignoreVary-
A boolean value that, when set to
true, tells the matching operation not to performVARYheader matching. In other words, if the URL matches you will get a match regardless of whether theResponseobject has aVARYheader. It defaults tofalse. cacheName-
A string that represents a specific cache to search within. Note that this option is ignored by
Cache.delete().
Return value
a Promise that resolves to true if the cache entry is
deleted, or false otherwise.
