Crop and resize images on the fly using node.js

Question

I am running node.js server on Amazon EC2. I get a huge csv file with data containing links to product images on a remote host. I want to crop and store images of different sizes on Amazon S3.

How can this be done, preferably just with streams without saving anything to disk?

Answer 1

I do not think that you can temporarily save a full-sized image to disk, since resizing / cropping / etc usually requires a full image file. So I say ImageMagick.
