auth_code_with_backend.js

/*
  This example demonstrates how to get an OAuth2 access token using a simple node
  backend server using the code flow.

  Once the server is started, navigate to https://localhost:3000 in the browser. You
  should be redirected to the OAuth2 URL after which the server will be given the
  authorization_code which will be exchanged for the access token.
