Failed to execute 'importScripts' on 'WorkerGlobalScope'

[Risingson]

I don't know what i am doing wrong but whatever i do i get a

Uncaught SyntaxError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The URL 'something.js' is invalid

error. Am i missing something. Should i be able to use importScripts with this?

as far as I know it should work. Does importScripts need to be an absolute path?

i think it needs the blob path since inline. but am still researching...
Currently reading here: https://www.html5rocks.com/en/tutorials/workers/basics/
Further down there is a chapter called "Loading External Scripts". It says:

"When using these techniques to inline your worker code, importScripts() will only work if you supply an absolute URI. If you attempt to pass a relative URI, the browser will complain with a security error. The reason being: the worker (now created from a blob URL) will be resolved with a blob: prefix, while your app will be running from a different (presumably http://) scheme. Hence, the failure will be due to cross origin restrictions."

But am not sure if that is the reason. I am using this for a mobile app so it needs to work in a file: environment.
