I am new to nodejs and am trying to set up a server where i get the exif information from an image. My images are on S3 so I want to be able to just pass in the s3 url as a parameter and grab the image from it.

I am u using the ExifImage project below to get the exif info and according to their documentation:

Instead of providing a filename of an image in your filesystem you can also pass a Buffer to ExifImage.

How can I load an image to the buffer in node from a url so I can pass it to the ExifImage function

ExifImage Project:
https://github.com/gomfunkel/node-exif

Thanks for your help!

Try setting up request like this:

var request = require('request').defaults({ encoding: null });

request.get(s3Url, function (err, res, body) {

      //process exif here

});

Setting encoding to null will cause request to output a buffer instead of a string.
