javascriptpdf.jspdfjs-dist

PDFJS cannot use a local worker file

I'm adding the workerSource pdfjsLib.GlobalWorkerOptions.workerSrc = './pdf.worker.js';

but still showing this warning in the console Setting up fake worker.

It works only when referencing the original file in github

pdfjsLib.GlobalWorkerOptions.workerSrc = '//mozilla.github.io/pdf.js/build/pdf.worker.js';
Solution

  • I had the issue because I already had an instance of the pdfWorker created when the file pdf.worker.js was loaded, I fixed it by adding this globalThis.pdfjsWorker = null; just before setting the workerSrc Like this I was able to create a new instance with the local file
