First, install NodeJS. It comes with NPM. Also, it might be easier to install with NVM to manage multiple versions.

Add APIKEY=myapikey as an environment variable.

Then run these commands:

git clone git@github.com:esha/wsdemo.git
cd wsdemo
npm install
cd dist
npx nf start -p 8000

Then direct your browser to http://localhost:8000/

To change the project, edit the html/css/js files in /app. Whenever you make a change, rebuild and restart by doing: cd .. && grunt && cd dist && npx nf start -p 8000

To deploy the app to Heroku, follow these instructions. Create your own Heroku app with:
heroku apps:create myappname Set your APIKEY: heroku config:set APIKEY=myapikey Deploy the app:
git subtree push --prefix dist heroku master For later updates, force the subtree push: git push heroku `git subtree split --prefix dist master`:master --force
