A tweak of @bolav's answer worked for me trying to work with pdfmake and not pdfkit. First you need to have memorystream added to your project using npm or yarn.

const MemoryStream = require('memorystream');
const PdfPrinter = require('pdfmake');
const pdfPrinter = new PdfPrinter();
const docDef = {};
const pdfDoc = pdfPrinter.createPdfKitDocument(docDef);
const memStream = new MemoryStream(null, {readable: false});
const pdfDocStream = pdfDoc.pipe(memStream);
pdfDoc.end();
pdfDocStream.on('finish', () => {
  console.log(Buffer.concat(memStream.queue);
});
