The matchAll()
method of the Cache
interface returns a Promise
that resolves to an array of all matching responses in the Cache
object.
The matchAll()
method of the Cache
interface returns a Promise
that resolves to an array of all matching responses in the Cache
object.
js
matchAll() matchAll(request) matchAll(request, options)
request
Optional
The Request
for which you are attempting to find responses in the Cache
. This can be a Request
object or a URL. If this argument is omitted, you will get a copy of all responses in this cache.
options
Optional
An options object allowing you to set specific control options for the matching performed. 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 — i.e. if the URL matches you will get a match regardless of the Response
object having a VARY
header or not. It defaults to false
.
A Promise
that resolves to an array of all matching responses in the Cache
object.
Note: Cache.match()
is basically identical to Cache.matchAll()
, except that rather than resolving with an array of all matching responses, it resolves with the first matching response only (that is, response[0]
).
The following example retrieves all responses in the v1
cache matching the URL /
, even including potential query parameters. By using { ignoreSearch: true }
, using matchAll
would retrieve /
as well as /?value=bar
.
It then logs the number of matching responses.
js
caches.open("v1").then((cache) => { cache.matchAll("/", { ignoreSearch: true }).then((responses) => { console.log(`Found ${responses.length} matching responses`); }); });
