Om in the Real World, A Case Study

While researching UX strategies for a hybrid mobile app, I stumbled upon a post by Christophe Coenraets, whom I remembered from the days when he was an Adobe technology evangelist. Today, still evangelizing, albeit for another employer, Christophe has moved on, like the rest of the world, to open standards, browser technologies. Said post dealt with the implementation of page transitions in a mobile client without mutating the DOM. I thought to myself, how sweet. But how sweet indeed to see this written in Clojurescript, for here is a language with a functional mindset that naturally embraces that which does not mutate.

tl;dr A Clojurescript port of a mobile-friendly, hardware-accelerated UI widget originally implemented in React.js.

The goal I wanted to achieve with my port was deceptively simple: replicate the exact same user experience, styling and performance, but in idiomatic Clojurescript. It was a fun little experiment, and I’ll let you, dear reader, be the judge. To the left is Christophe’s demo, to the right is mine. Can you spot the difference? I certainly can’t, and that’s the whole point. What is instructive to compare, on the other hand, is the source code driving the implementations. So go ahead, dive in the code. To the left is Christophe’s repo, to the right is mine.

The only thing left for me to do in the context of this post is to jot down a couple of observations.

Please let me know what you think.
