You need node installed.
Check the JS code with JSHint.
Just do
node web.js
Edit trappfika.js and set firebaseBaseUrl to something like https://your-db-name.firebaseio.com/
Install Protractor with
npm install -g protractor
On windows, it will install somewhere like **/Users/**/AppData/**/npm/node_modules/protractor
Run ./node_modules/protractor/bin/install_selenium_standalone to install selenium.
And then start it with selenium/start. I had to modify the start script slightly, adding .exe to chromedriver.
Have the static file server up and running.
Have the selenium server started.
Run tests like
protractor test/conf.js
