Angular & Google Login - Using Google Platform Library (GAPI) for Google Sign-In and GMail

We build an angular application with google sign-in and gmail API access using the google platform library (gapi). The Google Sign-In Javascript library is deprecated, clients can use the OAuth2 / OpenID Connect System of Google instead. I made a video about that: https://youtu.be/QV5YtczsorY (00:00) - Intro (01:52) - Get a ClientId in Google Cloud Console (04:02) - Include Google Platform Library (GAPI) (05:09) - Implement Google Sign-In (13:56) - Enable GMail API in Google Cloud Console (15:00) - Integrate GMail API (26:40) - Token Refresh (28:24) - Outro
