How to refresh expired google sign-in logins?

Question

I\'m using Google Sign-In. A user comes to my site and logs in with gapi.auth2.getAuthInstance().signIn(), or they are already logged in and when the page loads

Answer 1

FWIW, we've managed to (mostly) make it work via a listener approach. It appears that 'userChanged' callback is invoked ~5 minutes before the access token expires. That's enough for us to extract and update the access token without refreshing the page.

What does not quite work though is when computer comes back from sleep. This can be solved relatively easy by reloading the page on wake up.
