An actual door counter app (like we built on day 1)
npm install
npm build-client
npm start
Point your browser at http://localhost:5000/
cd server
npm start
Your server will now be running on port 5000. It will serve the latest build of the client application. If you do not have a latest build then that is OK too, just launch the client as below to work on the front end.
cd client
npm start
Note that there is a proxy defined in the client/package.json to redirect API calls to your server, so you MUST be running your server when working in development mode.
