Creating an Image Proxy server in Node.js
This will be a short post. I am writing this to document how I created a Node.js server that can act as an image proxy. I needed this to get around a limitation in HTML5's canvas implementation that prevents getting a loaded image's binary data if that image is from a different web domain. This function is very handy though if you're building an image editor so I had to find a work around.
My solution is to create an image proxy on the web server in question. I pass the url of the image I want to a specific route on my server and then it downloads the image data and returns it to my javascript thus hiding its true origins.
