    You can't access local storage from service worker – Aleksey L. Sep 17 '18 at 13:08

  • Hi Aleksey , do you know any work around for this? Actually i need to handle background notification click on my PWA app to display a different page. – abhishek gupta Sep 18 '18 at 07:21
  • You can use [postMessage](https://developer.mozilla.org/en-US/docs/Web/API/DedicatedWorkerGlobalScope/postMessage) – Aleksey L. Sep 18 '18 at 11:20

Synchronous APIs like localStorage, XHR as well as the DOM are not accessible in the service worker.

For storage you will need to use IndexedDB. It is not the easiest API to use directly. Instead I recommend a library that can make it as easy to use as localStorage.

I like localForage, https://localforage.github.io/localForage/
