In the article you write about sw but the comment on "An unknown error occurred when fetching the script. service-worker.js Failed to load resource: net::ERR_CONNECTION_REFUSED. " @ https://codelabs.developers.google.com/codelabs/pwa-workbox/#4

Awesome and i think the best article about pwa that I have read yet!

Thanks for the feedback @MannimMond86. I'm not sure I understand your question though, are you saying that you don't see the error (An unknown error occurred when fetching the script. service-worker.js Failed to load resource: net::ERR_CONNECTION_REFUSED. )?
