This app uses Node, ExpressJS and MongoDB for the Back-end and AngularJS for the Front-end, making it a fully MEAN App (no pun intended).
Following requirements, the Front-end App is totally independent from the API, so you'll need to move the Front-end wallapp folder to your WAMP/LAMP/XAMPP/Apache's root/www directory.
That's it! You're good to go!
