Generate pdf file using pdfkit and send it to browser in nodejs-expressjs

Solution 1:

doc.write is the line causing the trouble, which is also a deprecated method so don't use it. Instead, use pipe to tell your doc where to stream the information, and remember to close it using doc.end(), i.e., like so:

doc = new PDFDocument();
doc.pipe( fs.createWriteStream('out.pdf') );

// rest of the code goes here...

doc.end();

Note that it's not important that doc.pipe() be at the top, it just makes sense to me (you can put it before or after doc.end(). It doesn't matter, it'll work just fine). Finally, note that you can use pipe to stream directly to a response, there's no need to create the file first and then download it, i.e.:

doc.pipe( res )

Solution 2:

So Instead try Using

doc.pipe(res);
