React + Cognito User Pools + Cognito Identity JS Example
/*
This example was built using standard create-react-app out of the box with no modifications or ejections
to the underlying scripts.
In this example, i'm using Google as a social provider configured within the Cognito User Pool.
Each step also represents a file, so you can see how I've chosen to organize stuff...you can do it however
you'd like so long as you follow the basic flow (which may or may not be the official way....but its what I found that works.
The docs are pretty horrible)

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
