Data At The Speed Of Life – Reactive IoT Applications in Scala with Angular2

I had recently come off of a three year contract and found myself with some time on my hands. I was interested in working on an application that interfaced directly with some sort of small device. The director of our company, Don Coleman, had done a good bit of work with small devices so I spoke to him about the possibility of building a small application around those devices. He agreed to it and offered to assist from the hardware end. Our director of training, Ken Rimple, was researching the Angular 2 JavaScript framework at the time and offered to build the UI for the application. We eventually decided that we would build a demo to display at our booth at the 2016 South by SouthWest conference. This post explains our approach and some lessons learned.
