How to send a pdf file from Node/Express app to the browser

Question

In my Node/Express app I have the following code, which suppose to read a PDF document from a file, and send it to the browser:

var file = fs.createReadStrea         


        

Answer 1

Here's the easiest way:

app.get('/', (req, res) => res.download('./file.pdf'))

If this gives you trouble. Check the Express.js version or any middlewares that might be necessary.
