Good work, but how do I actually get this into lambda?

Hey there. Good work, but I can't figure out how to just drop this into lambda without all of the zappa and letsencrypt stuff. Shouldn't I just be able to drop in your app.js stuff into lambda? You'd think that the fine-uploader people would've made a drop-in lambda function to generate the signature already, but I guess not.
