Send image and JSON data in single Node.js + Express response

Question

I am creating a web API with Node.js and Express and intend to use a single response to return an image and JSON data simultaneously. I saw a solution to specify headers: https://stackoverflow.com/a/18864738/1703565 but I do not want to perform two get requests. How do I accomplish this?

You could encode the image as a base64 string (http://nodejs.org/api/buffer.html#buffer_buf_tostring_encoding_start_end), and return this as part of your JSON.
