Exporting Node.js code to AWS Lambda

I'm working on my mobile backend for my application using Amazon Web Services. I've decided to use Node.js for the inline coding possibilities, etc.

I'm using Atom.io for my javascript code and then im copying and pasting it in the inline editor. This process is being ridiculously slow..

Im wondering if there is a faster, better, more integrated way of editing your backend code?

The idea is to just work on one place but the inline editor on the website is very inefficient and only shows about 15-17 lines of code.

Exporting a .zip file doesn't seem any faster at all.
