Obsolete polyfill for the ServiceWorker cache API. Chrome 46 and Opera 33 support addAll now.


Take serviceworker-cache-polyfill.js, then in your ServiceWorker script:

// example usage:
self.addEventListener('install', function(event) {
  event.waitUntil('demo-cache').then(function(cache) {
      return cache.put('/', new Response("From the cache!"));

self.addEventListener('fetch', function(event) {
    caches.match(event.request).then(function(response) {
      return response || new Response("Nothing in the cache for this request");
