Can't resolve 'pdfjs-dist/build/pdf.worker.min.mjs in Nextjs 14 app router

[raibann]

Before you start - checklist

• I followed instructions in documentation written for my React-PDF version
• I have checked if this bug is not already reported
• I have checked if an issue is not listed in Known issues
• If I have a problem with PDF rendering, I checked if my PDF renders properly in PDF.js demo

Description

import { Box, CircularProgress, Pagination, Stack, Typography } from '@mui/material';
import React, { useState } from 'react';
import { DocumentText } from 'iconsax-react';
import 'react-pdf/dist/esm/Page/AnnotationLayer.css';
import 'react-pdf/dist/esm/Page/TextLayer.css';
import { Document, Page, pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = new URL('pdfjs-dist/build/pdf.worker.min.mjs', import.meta.url).toString();

const options = {
cMapUrl: '/cmaps/',
standardFontDataUrl: '/standard_fonts/',
};

/**

• Comp
  /
  const CustPreviewPdf = ({ file, disablePage }: { file?: File | string; disablePage?: boolean }) => {
  /*
  • States
    */
    const [totalPages, setTotalPages] = useState(0);
    const [pageNumber, setPageNumber] = useState(1);

/**

• Methods
  */
  const onDocumentLoadSuccess = ({ totalPages }: { totalPages: number }) => {
  setTotalPages(totalPages);
  };
  return (
  <>
  <Document
  file={file}
  onLoadSuccess={(value) => onDocumentLoadSuccess({ totalPages: value.numPages })}
  loading={}
  noData={
  <Stack direction={'column'} alignItems={'center'}>
  
  No PDF Imported
  
  }
  className={'disable-pdf-select'}
  options={options}
  {!disablePage && ( , page: number) => { setPageNumber(page); }} /> )}

</>

);
};

export default CustPreviewPdf;

Same here
it throws an error and the PDF is not rendered:

this worked for me

Check out this as well! Bun patch fixed it for me :D

I encountered the same error when using react-pdf in my Next.js (version 14) app during the build phase. It was working perfectly in development, but the error appeared during the production build.

@UmairJibran made a valid point, and while his solution might work for some, it didn't solve the issue for me. I fixed by replacing the following line:

 pdfjs.GlobalWorkerOptions.workerSrc = new URL(
   'pdfjs-dist/build/pdf.worker.min.mjs',
   import.meta.url,
 ).toString();

with this

pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.mjs`;

I switched to using the CDN, as specified in the docs

Here is the screenshot

I've encountered the same error too.

Building on top of @satyadalei's solution.

You can download the CDN and put it in the public directory and call it like this.

import { Document, Page, pdfjs } from 'react-pdf'

pdfjs.GlobalWorkerOptions.workerSrc = '/pdf.worker.min.mjs

Additionally, you might run into this error [ERROR] Promise.withResolvers is not a function Stack trace:

So, you have to add the polyfill

// Polyfill
// NOTE: pdfjs-dist is throwing Promise.withResolvers is not a function
// This is a workaround to fix the issue
if (typeof Promise.withResolvers !== 'function') {
Promise.withResolvers = function <T>() {
  let resolve!: (value: T | PromiseLike<T>) => void
  let reject!: (reason?: any) => void
  const promise = new Promise<T>((res, rej) => {
    resolve = res
    reject = rej
  })
  return { promise, resolve, reject }
}
}

export {}

Make sure to declare the type in your declaration.d.ts

interface PromiseConstructor {
 withResolvers<T>(): {
   promise: Promise<T>
   resolve: (value: T | PromiseLike<T>) => void
   reject: (reason?: any) => void
 }
}

Your component should look something like this

import 'path/to/polyfill'
import { Document, Page, pdfjs } from 'react-pdf'
pdfjs.GlobalWorkerOptions.workerSrc = '/pdf.worker.min.mjs'
