Forking React Scripts

Problem

You're using create-react-app but you need to do some customizations to the webpack configs while you wait for the CRA team to implement/have a solution for whatever it is you need.

BUT - you do not want to eject as you want to keep up to date with any changes in CRA and possibly eventually move away from your customizationed webpack config and go back to using the mainline.

Solution
