At this year’s DevNation/Red Hat Summit I was part of the team that created the Red Hat Summit Middleware keynote demo. I made the custom front-ends in the demo using Reactive Extensions for javascript (Rx.js) to manipulate the datastreams from the various back-end systems and to transform that data into a form that can drive the UI using d3.js. If you missed the keynote, you can watch it on YouTube below (the keynote demo starts at 19m).
I presented a Session on Rx.js at DevNation this year. My goal was to impress upon the audience how Observables can be interpreted as a collection-in-time. This analogy was very well described by @jhusain his Async Javascript at Netflix talk that initially got me excited about Reactive Functional programming. My contribution to this idea is to present it in a visual way. To visualize both a “regular” collection, as well as a collection-in-time, I used the d3.
