Module not found: 'worker-loader' when using create-react-app

[SrikanthChebrolu]

Error in ./~/pdfjs-dist/webpack.js
Module not found: 'worker-loader' in /Users/srikanthchebrolu/Developer/Project/srikanthchebrolu/node_modules/pdfjs-dist

@ ./~/pdfjs-dist/webpack.js 18:18-64

I used create-react-app to generate the project where webpack is not available directly. Can someone help me with this problem?

Hmmm. Maybe try installing worker-loader by yourself, then?

Hey @SrikanthChebrolu,
did my suggestion work?
I'm closing this issue to give active issues more visibility. If you still have this issue and want to talk, I'll be happy to reopen.
Cheers!

@wojtekmaj Actually not working. Using webpack@3.8.1, tried with version 3.x and 4.x and I get the same issue. Would be great if you have any tips.

Update, if anyone else needs it, in webpack use

resolve: {
    alias: { 'react-pdf': 'react-pdf/dist/entry.webpack' },
   ....
  },

then just import import { Document, Page } from 'react-pdf';

Hello,
Create React App 1.x will never support worker-loader, so you need to use generic instructions.

Create React App 2 will support worker-loader once facebook/create-react-app#3934 gets merged.
