Javascript Web Workers: Opera 10.60 Beta Supports Complex Messages
Opera 10.60 Beta was announced this week and along with the list of new HTML5 features it’s supporting was Web Workers. Of course I was excited to run it through the renderer/worker test suite I set up for my previous posts about Safari 5 and Chrome 5. The results were pleasing, the first Opera release […]

Javascript Web Workers: Safari 5 Now Supports Complex Messages
Following the announcement of Safari 5 [ 5.0 (7533.16) ] today, I did some due diligence and ran it through the json-object, array, boolean and string Worker message cases that I had produced for testing against Chrome 5. The results are in and thankfully consistent – so not much to report here accept that – […]

JavaScript EventSource: Now available in Firefox!
…Not natively… but this will work in the meantime: Git it here firefox-event-source.js ;(function (w) { if ( !w[‘EventSource’] ) { // parseUri 1.2.2 // (c) Steven Levithan <stevenlevithan.com> // MIT License var parseUri = function(str) { var o = { key: [‘source’,’protocol’,’authority’,’userInfo’,’user’,’password’,’host’,’port’,’relative’,’path’,’directory’,’file’,’query’,’anchor’], q: { name: ‘queryKey’, parser: /(?:^|&)([^&=]*)=?([^&]*)/g }, parser: { strict: /^(?:([^:\/?#]+):)?(?:\/\/((?:(([^:@]*)(?::([^:@]*))?)?@)?([^:\/?#]*)(?::(\d*))?))?((((?:[^?#\/]*\/)*)([^?#]*))(?:\?([^#]*))?(?:#(.*))?)/ } […]

JavaScript Web Workers: Motörmouth is a Twitter Client
About a month ago, I released jQuery.Hive/Pollen, a plugin + library for developing jQuery applications that use Web Workers. And as per usual, the number one question is “what can I do with workers?”. With that in mind, I decided that at least every month (and hopefully even more frequently then that) I would produce […]

Chrome 6: Server Push Events with new EventSource()
This is mighty awesome. 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’, […]

Javascript Web Workers: Chrome 5 Now Supports Complex Messages
After updating to Chrome 5 (specifically 5.0.375.55) last night I immediately ran some tests to see if the Web Worker API had been updated to support postMessage() arguments of types other than string. Turns out, it had. 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 […]

Javascript Web Workers: From Basics to jQuery.Hive, Part III
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. Inititally it began it’s life as PollenJS a jQuery-looking library of functions that were light, useful and thread-safe. This was before the WebKit implementation existed so everything was […]

Javascript Web Workers: From Basics to jQuery.Hive, Part II (Browser Implementations)
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). […]

Javascript Web Workers: From Basics to jQuery.Hive
This is long overdue. Also, it should serve as a context for my slides from jQuery Conference, San Francisco 2010 (use the up and down arrow keys to navigate). 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 […]
