Matthew Podwysocki and Bart J. F. De Smet: RxJS Today and Tomorrow

42 minutes, 14 seconds


Right click “Save as…”

The JavaScript implementation of Reactive Extensions (Rx), RxJS, continues to evolve under the direction of Matthew Podwysocki. RxJS provides Rx operators in JavaScript and it does this in a download size of less than 7KB (using GZip compression). RxJS provides easy-to-use conversions from existing DOM, XmlHttpRequest (AJAX), and jQuery events to Rx push-collections, allowing users to seamlessly plug Rx into their existing JavaScript-based web sites.

Here, Bart J.F. De Smet - the lead developer of Rx - and Matthew sit down for a C9 conversation about RxJS (no demos or code-on-screen - this is purely a conversation). Who knows where it will go (will we only talk about RxJS?) and who'll make a cameo appearance at the very beginning Smiley Tune in.

    Kudos to Rx team.

  • Always great to see Erik Meijer!! .. btw .. Rx is a great technology ... 

  • ChevalN2Cheval Why not null?

    To take Charles point about what to do with Rx further, I often hear "you guys get a new technology and treat it like a hammer and then try to treat everything else as a nail whether it is or not." To that, well of course! How else can you learn something without living it for a time, to know what it is and how best to use it. That being the case, Rx seems like "well you don't need it until you try and do x, y or z..." That's the learning curve problem with Rx, there are not enough nails around to go bashing with it. The tutorial series was a start but like the All-In-One project, how about list somewhere of examples of how Rx can solve problems and maybe like I suggested to the All In One group, accept request for scenarios and show how Rx is best to solve them.

    Any way, keep on with the documentation, but examples of solved problems is just sometimes better for us dark matter developers.

  • Could you include a link off to the github repo?
