At dealini we needed to build a responsive web application for the Monsterdeals marketing campaign for our client Valora (kkiosk). People would get actual cards at the counter which they had to collect to get a certain discount or gift. So they could enter the codes of their cards in either our mobile or web app.
We evaluated the upcoming SPA frameworks available at the time and went for the google backed AngularJS-framework. Other technologies we used in our stack were Bootstrap, Grunt, Yeoman.
