I’ve put together some test demos, to run them you’ll first need to get this Chromium build: 47357 WIN32 47357 MAC 47357 32-Bit Linux 47357 32-Bit Linux Then download these: https://gist.github.com/415116 client.html <script src=”event-source.js”></script>; event-source.js document.addEventListener(‘DOMContentLoaded’, function () { var eventSrc = new EventSource(‘events.php’); eventSrc.addEventListener(‘open’, function (event) { console.log(event.type); }); eventSrc.addEventListener(‘message’, […]

Here’s the test, plus the results: https://gist.github.com/414901 renderer.html <script src=”renderer.js”></script> renderer.js var worker = new Worker(‘worker.js’); worker.addEventListener(‘message’, function […]

I’m a jQuery enthusiast. Maybe even an evangelist. So I decided to make workers easy for my fellow jQuery developers – and thus was born the jQuery.Hive.

As I mentioned in Part I, the Web Worker API is available for use in Firefox 3.5+, Safari 4+ and Chrome 4+, however the implementations are inconsistant. This has been completely overlooked by every single tutorial I’ve found. The issue revolves around the accepted argument to postMessage() (from both the main window and the worker). […]

Whether or not you’ve read the WHATWG Web Worker spec and are looking for more information about Javascript multi threading OR you already have a rudimentary […]

Yesterday, I was introduced to Javascript Web Workers during a bad-ass FireBug console hack-session with Al MacDonald (http://hyper-metrix.com). I have to say… this is the coolest thing I’ve seen in a very long time… Workers are currently available in FireFox 3.5, Safari 4 and (according to John Resig) the Chromium Nightlies. I’d like to consider […]
