The only thing I've seen so far is the [http://code.google.com/apis/gears/api_workerpool.html Google Gears WorkerPool API]. We would certainly like to provide a API that would make migrating Gears code trivial. | The only thing I've seen so far is the [http://code.google.com/apis/gears/api_workerpool.html Google Gears WorkerPool API].

== API Proposal For Shared Workers == | |||
If we want to support shared workers in the initial release of this spec, here are two proposals that will work with the above initial API. | |||
=== Proposal 2 === | |||
<blockquote> | |||
<code> | |||
<pre> | |||
[NoInterfaceObject] interface WorkerFactory { | |||
... | |||
Worker createSharedWorker(in DOMString name, in DOMString scriptURL); | |||
}; | |||
</pre> | |||
</code> | |||
</blockquote> | |||
<code>createSharedWorker</code> creates a new <code>Worker</code> object that interacts with the same <code>WorkerGlobalScope</code> as any previously existing <code>Worker</code>s. When <code>postMessage</code> is called from within a shared <code>WorkerGlobalScope</code> all connected <code>Worker</code> objects will received that message through their <code>onmessage</code> property. | |||
