In the following file /lib/pdf.js

`let _basePath = __dirname + "/../base/";
let _fileContent = '';

_pdfjsFiles.forEach( (fieldName, idx, arr) => _fileContent += fs.readFileSync(_basePath + fieldName, 'utf8') );`

In My project i am doing something
import PDFParser from "pdf2json";

I have the same problem. I am trying to use pdf2json in an AWS lambda using serverless. __dirname is a node internal variable that is meant to get the directory that the active file is in, which is "/lib" in this case. In my case, the __dirname variable seems to be altered by the Webpack JS bundler. Apparently the default __dirname for webpack is set to '/'.
In the webpack.config.js file, I tried to fix the problem by adding the line:

target: 'node', node: { __dirname: false, },

But that only changed the __dirname string to the directory where the file is required from rather than the actual folder where the pdf.js file is located, causing the same error because the ../base directory does not exist there.
I also tried setting __dirname to true instead of false in the webpack.config.js file, which results in the __dirname string to be "node_modules/pdf2json/lib". Since this is still not an absolute file path, the error still persists.

I have the same problem - when trying to run the function on "netlify functions".
It would be greatly appreciated if any one could provide info on how to fix or work around it,

Context

This is the "offending" code. I guess this is done to share context between several javascript files. Patching this is not trivial, and several files work under this global scope and shared variables assumption.

// lib/pdf.js
let PDFJS = {};
let globalScope = {console: console};

let _basePath = __dirname + "/../base/";
let _fileContent = '';

_pdfjsFiles.forEach( (fieldName, idx, arr) => _fileContent += fs.readFileSync(_basePath + fieldName, 'utf8') );

eval(_fileContent);

Webpack has a hard time with dynamic imports, and should never waste time supporting this use case (that is way crazier).

A webpack workaround

A quick fix for anyone interested is just skipping this package in webpack and copy it over to wherever your bundle is.

I used copy-webpack-plugin
and added pdf2json as an external dependency

// webpack.config.js
const CopyPlugin = require('copy-webpack-plugin');

const dontBundlePdf2Json = new CopyPlugin({
  patterns: ['node_modules/pdf2json/**/*'],
});

module.exports = {
  /* all the other configuration */
  externals: ['pdf2json'],
  plugins: [dontBundlePdf2Json],
}

This will result in:

project/
├── dist/
│   ├── node_modules/
│   │   └── pdf2json/
│   │       └── ... all the library's files
│   └── bundle.js
└─── src/ 

And the node module resolution works as expected.

Bruh why you use wacky module resolution and eval

[JinhooBong]

Has the copy-webpack-plugin solution worked for anyone? It has not resolved the issue for me.

I'm having this same issue when packaging an Electron app - the webpack copy plugin workaround hasn't worked but I'm still tinkering.

Uncaught Exception:
Error: ENOENT, dist/base/shared/util.js not found in <project>/release/build/mac-arm64/ElectronReact.app/Contents/Resources/app.asar
at createError (node:electron/js2c/asar_bundle:2:1312)

Are there any other trivial workarounds?

Edit:

a workaround for Electron for anyone interested is to copy the pdf2json base/ directory using the extraResources object within package.json[build].

"extraResources": [
      "./assets/**",
      {
        "from": "./release/app/node_modules/pdf2json/base",
        "to": "app/dist/base",
        "filter": [
          "**/*"
        ]
      }
    ],

I also had to set "asar": false, which isn't recommended for performance reasons, but this wasn't an issue for me.

A fix plus appropriate tests are in PR #338, please review and test it out

[modesty]

fixed in 3.1.2

[isitgeorge]

@modesty Thank you for fixing!

I've only just had some time to test and it seems to work without issue when packaged as part of an Electron app.
