This app is sort of haphazardly thrown together in order to illustrate React Router 4 + Passport. There is * a lot * to clean up! Tread carefully. It is a combination of create-react-app (code in src/ dir is client code) and User Authentication with Passport and Express 4.
To get this operational, you need to open two tabs and use the following commands - 1 in each tab:
npm run start:client
to start webpack watching and building your client-side code into the build/ directory, and
npm run start:server
to start nodemon watching your code in the server/ directory and serving everything on localhost:3000
NOTE: the static index.html and code inside of build/ dir are served by express static configuration.
