How to get the binary data from a pdf and send back as response

Question

I created a PDF of a website using puppeteer from a link provided by the client, and now I need to send back as response the stream code/ octet stream / binary data of this pdf, I am unsure how to do that can someone help me

I have the PDF stored locally in the same folder as my js file

Answer 1

Just use

response.body = fs.readFileSync("path/to/file.pdf");

in KOA.

This will automatically send the pdf file as an application/octet-stream.
