Create base64 string in pdfKit

How to get base64 string instead the blob pdf encoding? My approach does not work and I get the pdf blob in frontend instead base64.

  const pdfName = "cv123.pdf";
  const pdfPath = path.join('data', pdfName)
  const pdfDoc = new PDFDocument();
  pdfDoc.pipe(fs.createWriteStream(pdfPath, {encoding: "base64"}));
  pdfDoc.pipe(res)
  pdfDoc.text("TEST").fontSize(20)
  pdfDoc.end();

My solution was to create read stream from the created PDF by the PDFkit, it works

const pdfName = `cv123${orderId}.pdf`;
  res.setHeader("Content-Type", "application/pdf");
  res.setHeader("Content-Disposition", `attachment; filename=${pdfName}`);
  const pdfPath = path.join("data", pdfName);
  const pdfStream = fs.createWriteStream(pdfPath);
  const pdfDoc = new PDFDocument();
  const writeStream = pdfDoc.pipe(pdfStream);
  pdfDoc.fontSize(25).text(`Order ${orderId}`);
  pdfDoc.fontSize(13).text(`User ${orderUser.name}`);

  pdfDoc.end();
  writeStream.on("finish", () => {
    const fileStream = fs.createReadStream(pdfPath, { encoding: "base64" });
    fileStream.on("data", (chunk: Buffer) => {
      res.write(chunk);
    });
    fileStream.on("end", () => {
      fs.unlink(pdfPath, () => {
        res.end();
      });
    });
  });
