Method to run worker from other origins.
Workaround for the following error:
Uncaught (in promise) DOMEXception: Failed to construct 'Worker' (...) cannot be accessed from origin (...)
This solution doesnt break importScripts.
This method allows to use BarcodeDetector in a Worker from 3rd party origin.
npm install crossoriginworker
import getCrossOriginWorkerURL from 'crossoriginworker';
async function createWorker() {
const workerURL = await getCrossOriginWorkerURL('https://somedomain.com/lib/awesome.worker.js');
return new Worker(workerURL);
}
const myWorker = await createWorker();
CrossOriginWorker has several options, that might be useful in some instances:
getCrossOriginWorkerURL(url, OPTIONS);
When worker is hosted on the same domain, load it right away.
Create additional proxy Blob that contains worker code. Disable in case of problems.
