Using cordova in web workers
Is it possible to use cordova inside a web worker? I tried importing the
cordova script but it makes reference to 'window' which is forbidden in
web-worker context.
It would be useful to be able to call cordova functions from within a
web worker.
Cheers,
Mike

Yes, as will the call to cordova.exec so there is little benefit in using a worker here, unless you wanted to do a bunch of work, and then call exec.

And stringByEvaluatingJavaScriptFromString will always run in the
context of the main window rather than the web worker, I presume?

No is working on this that I know of. XHRs from a worker would likely kick
the native bridge fine, so long as the user-agent of the worker is set
correctly.
Problem is that the native side does a stringByEvaluatingStringFromString
to retrieve the payload of the exec() command, as well as to send responses.
Probably the best way to implement this would be to have exec() from the
worker use postMessage() to route them via the main window.

Will XHRs to gap_exec within a web worker already be intercepted by
cordova, or do both the native and javascript sides need to be updated
to support calling cordova APIs from within a web worker?
In either case, has any progress been made on this in a public repo?
Thanks,
Christian

I'm getting into a refactor of cordova.js and will keep this in mind while
I'm in there. Like Andrew says things are somewhat coupled at the moment
but that doesn't mean it has to be.

It could be made to work, but would certainly require some effort.
