Building on top of AlienWebguy's answer, if you are in an async function, you can do the following:

import { once } from 'events'

async function main () {
  const doc = new PDFDocument(); 
  // do stuff here
  const writeStream = fs.createWriteStream('output.pdf')
  doc.pipe(writeStream);
  doc.end();
  await once(writeStream, 'finish');
}

When main() finishes executing, you are garanteed that the stream is done writing to disk and can safely manipulate the file again, or exit the process.

You probably have an async issue where you're trying to access/return the doc before it's done writing to disk.

Fix with a handler : 

writeStream.on('finish', () => { .. your code here .. });
