How do I save buffer as PDF in client side(in browser on response as buffer) ?

This is how I sending buffer in the response.

htmlToPDF.create(finalHTML, options).toBuffer((err, buffer) => {
                         if (err) {
                           res.json(responses.genericError(500, 'Internal server error.'));
                         } else {
                           res.type('application/pdf');
                           res.statusCode = 200;
                           res.send({ data: buffer, success: true });
                         }
                       });

This is the code that I’ve written to download pdf on the client side,

    res.writeHead(200, {
      'Content-Type': 'application/pdf',
      'Content-disposition': `attachment; filename=test.pdf`,
    });

    pdf.create(html, option).toStream((err, stream) => {
      stream.pipe(res);
    });

@lowzijian If you have res.setHeader('Content-disposition', 'attachment; filename=export-from-html.pdf'); // Remove this if you don't want direct download It will automatically popup the “file open or download” on the response of your “controller”. But if you comment this line, your browser will open the stream with a PDF reader (eg Firefox).

Here is my code if you want :

const html_pdf = require('html-pdf');

    res.render('pages/index', { res: res },function (err, html) {
        const html_for_pdf = "<h1>Am I a true HTML ?</h1>";
        html_pdf.create(html_for_pdf ).toStream((err, stream) => {
          if (err) return res.end(err.stack);
          res.setHeader('Content-type', 'application/pdf');
          res.setHeader('Content-disposition', 'attachment; filename=export-from-html.pdf'); // Remove this if you don't want direct download
          res.setHeader('Content-Length', ''+stream.length);
          stream.pipe(res);
        });
    });
