JavaScript Web Workers: Support & Testing The Browser
In case you’re not yet familiar, the JavaScript Web Workers API is a feature that facilitates the execution of scripts in an independent background process, away from any UI related logic. It should be assumed that the Worker’s life-cycle is the same as the application that called it, as it comes with start-up and instance […]

Javascript Web Workers: Chrome 5+ supports new SharedWorker()
In my excitement and haste upon discovering new SharedWorker() support in the Opera 10.60 Beta, I neglected to snoop around the window object of my two favorites, Chrome 5+ and FireFox 3.6+ … WHOOPS! If I had done so, I would’ve discovered, as I did just now, that Chrome 5+ ALSO supports new SharedWorker(). Of […]

Javascript Web Workers: Opera 10.6 Beta Supports SharedWorkers
While poking around the Web Worker API in the latest Opera Beta Release, I discovered that they had also implemented support for Shared Web Workers. If you’re not familiar with Shared Web Workers, have a look here. The basic premise is that a Shared Worker can have multiple connections made to one Worker. Paraphrased from […]

Processing Pixel Data with Web Workers…
One of the questions that came up in the Processing track was: “Can you pass the image data from a Canvas to a Web-Worker for processing?” My assumption was “yes” as the specs declare you can paste any complex object to and from workers so long as you’re not trying to pass a DOM element. […]

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 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 […]

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). […]
