firestore?

How might one modify this to use the firestore database instead?

I never used Firestore myself, so I cannot tell. But the React boilerplate should be pretty similar, shouldn't it? Only the API layer (files) to the Firebase/Firestore should change. And the callback for a logged in user from the withAuthentication and withAuthorization HOCs should be different as well.
