Herding Code 80: RxJS with Jeffrey van Gogh and Matt Podwysocki

This week on Herding Code, the guys speak with Jeffrey van Gogh and Matt Podwysocki about the Reactive Extensions for Javascript.

  • Matt talks about how he’s been involved with RxJS.
  • Jeffrey talks about how RxJS and Reactive Extensions came out of the the Volta project.
  • Matt talks about how RxJS simplifies the callback model in Javascript.
  • Jeffery adds on how this also has benefits to asynchronous operations.
  • Jon asks about how this works with queries over events which will happen in the future.
  • Mat talks about how this works with jQuery’s bind and live events.
  • Jon asks the standard question about querying over mouse move events. Matt and Jeffrey use the example to explain about how composable operations over events can be really powerful.
  • Jon asks how Reactive Extensions relates to functional reactive programming, and to functional programming in general.
  • Kevin asks about how RxJS interoperates with jQuery.
  • We take questions from Twitter about jQuery integration and use of RxJS to manage script loading and script scoping.
  • Kevin asks for some concrete usage examples.
  • Kevin asks about the library size and the overall release status.
  • Jon asks about Jeffrey’s blog posts on using RxJS with Node.js and Script#.
  • We talk about Matt’s extensive blog post series on RxJS.
  • We talk about recent RxJS presentations: Erik Meijer’s talk at MIX10, Jeffrey’s talk at JSConf, and Matt’s at the Imagine Cup.
  • Jon asks about what exactly is involved in adding RxJS support to different Javascript libraries.
  • Scott K asks about the tradeoffs of bringing the CLR to the browser vs. bringing things like RxJS into the browser via Javascript.
  • We talk about how Javascript development has gotten easier with development environment improvements, testing systems, etc.
  • Matt talks about how it’s often easier to do things in Javascript than in a statically typed language like C#.
  • Scott K asks about how scope is handled in RxJS.
  • Jon asks about how the code is licensed.
  • Kevin asks about the naming conventions used in RxJS, supported browsers, release plans.
  • Jon asks about Reactive Extensions for .NET, and we talk about how it’s especially useful in Silverlight.
  • Jeffery mentions that Reactive Extensions will be included in Windows Phone 7.
  • We pretend to end the show, but the discussion keeps going and K Scott joins the party.
