Install pdfjs-dist

import { Document, Page, pdfjs } from "react-pdf";
import pdfjsWorker from "pdfjs-dist/build/pdf.worker.entry";

pdfjs.GlobalWorkerOptions.workerSrc = pdfjsWorker;

Reference: https://github.com/mozilla/pdf.js/issues/8305

UPDATE

react-pdf >= 9.0.0

import { Document, Page, pdfjs } from "react-pdf";
import { WorkerMessageHandler } from "pdfjs-dist/build/pdf.worker.min.mjs";

pdfjs.GlobalWorkerOptions.workerSrc = new URL(
  WorkerMessageHandler,
  import.meta.url
).toString();

This also fixed a known issue:

Failed to load module script: Expected a JavaScript-or-Wasm module script but the server responded with a MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec.

found a more efficient way of including the worker by including the library from the dependencies of react-pdf itself, this way you will never get a version mismatch like this The API version "2.3.45" does not match the Worker version "2.1.266"

if you install pdfjs-dist manually you will have to check react pdf dependency version on every build

import { Document, Page, pdfjs } from "react-pdf";
import pdfjsWorker from "react-pdf/node_modules/pdfjs-dist/build/pdf.worker.entry";

pdfjs.GlobalWorkerOptions.workerSrc = pdfjsWorker;

see similar error on pdfjs library : https://github.com/mozilla/pdf.js/issues/10997

pdf.worker.js and other js files make for a large client download

See https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#minified. 2. If you know that some functionality is not used in your PDFs, e.g. JBIG2, JPX, some font types, you can build your own pdf.worker.js with only functionality you need.
