Cache.matchAll()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The matchAll() method of the Cache interface returns a Promise that resolves to an array of all matching requests in the Cache object.

Syntax

JavaScript
cache.matchAll(request,{options}).then(function(response) {
  //do something with the response array
});

Returns

a Promise that resolves to an array of all matching requests in the Cache object.

Note: Cache.match() is basically identical to Cache.matchAll(), except it resolves with response[0] (i.e. the first matching response) instead of response (all matching response in an array).

Parameters

request
The Request you are attempting to find in the Cache.
options Optional
An options object allowing you to set specific control options for the matching done in the match operation. The available options are:
  • ignoreSearch: A Boolean 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 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 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.
  • cacheName: A DOMString that represents a specific cache to search within. Note that this option is ignored by Cache.matchAll().

Examples

JavaScript
caches.open('v1').then(function(cache) {
  cache.matchAll('/images/').then(function(response) {
    response.forEach(function(element, index, array) {
      cache.delete(element);
    });
  });
})
