This is a minimal Progressive Web App (PWA) that demonstrates:

• How to create a PWA
• How to install a PWA as a desktop app
• How to call a Chrome extension from a PWA

I manually tested this works via localhost or over a ngrrok tunnel.

The service worker in the PWA won't work if you open the index.html file directly in the browser, or if it's served over HTTP (not HTTPS) on non-localhost.

To run the HTTP server that serves the PWA, run:

go run .

Then open http://localhost:8080 in your browser.

If you are developing over a remote connection, you can use ngrok to tunnel the localhost to a public URL:

ngrok http http://localhost:8080

Then open the ngrok URL in your browser.
