Jared Hanson, the maintainer of the Passport libraries has updated passport-google-oauth20 to address the Google+ API shutdown, as well posting about it on Medium:
https://medium.com/passportjs/google-api-shutdown-330c3b47e3df
Per the article, using the 2.0 version of the package is all that is necessary, no code changes are needed. When we installed the Passport library in the "Passport Setup" video, it should have installed this version by default.
You can check your package.json to make sure:
"passport-google-oauth20": "^2.0.0",
In the coming lectures, Stephen will show how to enable the Google+ API. Since it does not exist anymore, this step can be ignored as we will be using the Passport library to instead source the Google profile from the "userinfo" endpoint.
