I worked my way through Learning Node.js by Marc Wandschneider. I highly recommend this excellent book as a starting point for getting up and running with Node.js.
This repository contains all of the code I wrote while following along with the book, including sample code and coding projects.
Most of the code was originally authored by Marc Wandschneider, but I have updated it to use more modern JavaScript constructs (such as using template literals instead of string concatenation). The unaltered source is available on Marc's Github in this repository.
