It should work if you import it correctly.

pdfjsLib.GlobalWorkerOptions.workerSrc = "https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.6.347/pdf.worker.min.js";

var loadingTask = pdfjsLib.getDocument("dummy.pdf");
loadingTask.promise.then(function(pdf) {
 console.log(pdf);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.6.347/pdf.min.js"></script>

In React it should be something like this:

import * as pdfjsLib from "pdfjs-dist";
pdfjsLib.GlobalWorkerOptions.workerSrc = `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjsLib.version}/pdf.worker.min.js`;

const loadingTask = pdfjsLib.getDocument("dummy.pdf");
loadingTask.promise.then(function(pdf) {
  console.log(pdf);
});
