Building OAuth Strategies with passport.js Chapter 7Creating and setting up a Google app
Just as we did for the Facebook and Twitter strategies, to be able to use the Google Strategy,
we have to build a Google application. The developers, portal for Google is at https://
console.developers.google.com/.
Then, click on the drop-down list of the projects, which lies at the top-left corner of the
page. A popup will show up. Then, click on the + icon to create a new application.
You just have to add the name of your application. We will name the application
movieratingapp, as Google does not allow underscores or any other special characters:
When the application gets created successfully, click on Credentials and Create and then
on OAuth Client ID to generate the app tokens. To generate the tokens, we will first need
to Enable the Google+ API via Developer Console at https://console.developers.
google.com/.
