A node.js script that resizes images on-the-fly.
Specify a ROOT_DIR environment variable to tell this script where to find the images. Then include a
/[width]x[height]/
directory in front of the image path you're requesting. The script uses sharp to resize the image to the specified dimensions and return it. It's especially handy if you use this behind a CDN like CloudFront so you don't have to resize the images with every request.
