node-csi
This is something that I've found myself writing over and over again (or at least parts of) for the various projects that I've worked on. ANSI color schemes were all the rage growing up (yes I'm old) and I've written a few different things in node.js now where I've desired more color than the console typically delivers these days.
How It Works
Based largely in part on the information present in the wikipedia page on ANSI escape codes, this small modules attempts to make it easier to colorize the output in various projects and do simple things with the cursor.
I'm honestly not sure if this version is at all the way I'd like to continue using the product but it is good enough to base a few other of my features on.
Version
1.0.2 - This is essentially the first commit and provides basic functionality with very little documentation or extensibility.
Potential Plans

All of the following features are dependant upon your terminal program and it's capabilities.

Caveats
Not all of these features are tested as my terminal doesn't support all of them. That being said, if you find a bug or wish the library functioned differently, let me know. I'm not convinced I like it very well myself just yet.
