I did create a solution so you can generate a pdf, without saving the file, and send it as response. The problem was that adonis.js does not support pipe the pdf into response and send as an attachment.

// you have to download the dependencies
import blobStream from 'blob-stream';
import PDFDocument from 'pdfkit';

// put it inside controller function
const return_pdf = new Promise((resolve) =>
{
  const doc = new PDFDocument();
  // create elements
  doc.text('test');
  doc.end();

  the_stream.on('finish', () =>
  {
      let pdfData = Buffer.concat(buffers);
      response.header('Content-type', 'application/pdf');
      response.header('Content-Length', pdfData.length);
      response.header(
        'Content-disposition',
        'attachment; filename=test.pdf'
      );
      response.send(pdfData);
      resolve(true);
  });
});

await return_pdf;
