This is from the request's Github repo - https://github.com/mikeal/request
You can stream any response to a file stream.
request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
I have modified it like so, where largeImage is a absolute url path from 3rd-party website.
request(largeImage).pipe(fs.createWriteStream('./img/large/demo.jpg'));
But I get the following error (not sure why?). I have looked at the createWriteStream API and it seems to be correct. If I only include "demo.jpg" it works fine. But if I include path next to "demo.jpg" it throws an exception.
stream.js:81
throw er; // Unhandled stream error in pipe.
^
Error: ENOENT, open './img/large/demo.jpg'

UPDATE: The problem was I didn't include ./public/ folder before the /img/.
This updated code works correctly:
request(largeImage).pipe(fs.createWriteStream('./public/img/large/demo.jpg'));
It all looks OK. My guess is that the issue is related to permissions or maybe needing to create the ./img/large directory first.
Do something like this to get more info:
var ws = fs.createWriteStream('./img/large/demo.jpg');
ws.on('error', function(err) { console.log(err); });
request(largeImage).pipe(ws);
