Download the source files for this Angular app. Create your own repository on GitHub and submit this project.

git clone https://github.com/jojozhuang/game-store-angular.git

We will use express to serve our angular app in heroku. Check the posting Deploying Angular App to Heroku with Express Server to make the required changes to Angular app.

1.3 Travis Config File

Create a file named ‘.travis.yml’ in the root folder. Submit this file to GitHub as well.
