  • Run Your Javascript Everywhere, with Jellyfish.

    by admc

    h2. Introduction

    We want to believe that every Javascript environment runs code the same way, but that just isn’t the case — and until now, there was no easy way to find out.

    Currently the most popular place for Javascript to break is in browser environments, but there is a growing urgency for mobile environments and the server side.

    h2. History

    At OSCON in 2007 we announced Windmill, designed to launch browsers and simulate users. User simulation in the browser is awesome and useful — but now it’s more important to be able to run all that JS logic that we care about so much. This spawned a complete re-thinking of the problem.

    h2. Architecture

    Jellyfish is a node module, which knows how to initialize the environment you need, facilitating a communication channel to tell it what to do. However, the best way to understand how the system works is best done with a giant awesome looking graphic, which I will be happy to provide and walk through.

    h2. Setup

    How do you get Jellyfish setup to run that first ‘hello world’? It’s easy, let’s all do it together.

    h2. Do things better

    Remember how all the testing tools out there try to either proxy the entire internet, or move all their logic away from Javascript and onto native operating system code? Yeah, there is a better way to do that — I think you’ll like it.

    h2. Reporting

    With one line of code, you can post everything your jellyfish scripts do and their results into couchdb, let’s talk about how to make that happen, and what you can do with those results.

    h2. The future

    I’ve had requests for environment support for Adobe Air, Ruby Racer, and Web OS — lets talk about what the development plan is for Jellyfish.

    h2. THANKS!

    Jellyfish is fully Open Source software hosted on Github, and I would be happy to take your patches!
