Hi folks, I'm excited to tell you my Opal library that brings Knockout.js to the Ruby front-end is here! http://polished-rb.github.io/knockout-rb/
I know React is the new hotness and there's such great work being done around that, but I've been a fan of Knockout for a long time and I feel it's important to be able to make it available to Opal devs. This is also the first of several components of a larger project I'm working on called Polished. Eventually, Polished will provide a number of loosely-coupled components that comprise a front-end framework that plugs super easily into any standard Rails project. For most of it, I'm simply extracting some patterns and shortcuts I've used in my own Rails/Opal projects, so it's not just theoretical. :) Anyway, check out (star!) Polished: Knockout and let me know what you think!
