Since I’ve been working with node.js quite a bit lately, to build a better mental model of how it works, I wanted to spend some time walking through it’s source, and learning a bit about how it works.

I feel like I’m constantly runnining into issues debugging web applications that communnicate over the network in a variety of ways. When services need to talk to standalone applications that I can’t easily debug, I find that having access to some networking tools to do some debugging can save a lot of time, compared to trying to figure out what’s going on some other way.
