React.js with Redux authentication using Google OAuth2

In order to authenticate a React.js web application using Google OAuth2 , you first need to sign into the Google API Console. Select the “Credentials” menu item and then “CREATE PROJECT”.

For the purpose of this tutorial I just called my project “Medium Tutorial”. Selecting an Organisation and Location is mandatory. I’m not sure exactly where I created this as I did it a long time ago. I think if I remember correctly it was part of the Google Developers sign up.

You will need to “CONFIGURE CONSENT SCREEN”. You can see it in the screenshot below next to the warning message.

Unless you have an internal company specific requirement you will probably want to select “External” here and click “CREATE”.
