Does not work in create-react-app due to stubbed out 'fs' module (Throws 'exists' is not a function)

[riyavsinha]

As per facebook/create-react-app#3074, the 'fs' module is stubbed out as empty when using create-react-app (printing an imported 'fs' module returns {}).

Importing modules using this module as a dependency therefore always throw with TypeError: 'exists' is not a function.
