I just attended a conference talking about Functional Reactive Programming in the Netflix API and it’s pretty cool subject to talk about. I google and found that Rx is also available for Node.js https://github.com/Reactive-Extensions/RxJS but I don’t see much blog out there showing show to use RxJS with express.js. It would be cool and very helpful if we have a post explaining the usage of Express.js and RxJS.
