Is there a way to import the pdfreader into a commonjs solution?
This would had been my approach: let PdfReader = import("pdfreader"); but PdfReader is not a constructor.

Thanks

Here's how to import and use pdfreader from a commonjs project:

import('pdfreader').then(({ PdfReader }) => {
  new PdfReader().parseFileItems(
    'file.pdf',
    (err, item) => {
      if (err) console.error('error:', err);
      else if (!item) console.warn('end of file');
      else if (item.text) console.log(item.text);
    },
  );
});

As explained in How to run ES packages in CommonJS modules, the trick is that the call to import actually returns a Promise.
