Angular 5 with CacheStorage

Question

im trying to use CacheStorage\'s promises in Angular 5 like in the docs :

let test = caches.open(\'test\');
    test.then((result : Cache) => {
      result.a         


        

Answer 1

This is easy to miss -

1) CacheStorage API (or Cache API) are only available on localhost and HTTP/2.
2) For purists reason, prefer to use window.caches.open(CACHE_NAME) as caches is a singleton instance present in window object.
