Until recently I've had a random text tools file sitting in a few of my Node projects that has just been copied from each project to the next. It just contained a couple of simple text functions that I used a lot (eg. slugifying a string) but didn't seem to have an actual home in the project.
I figured that a better approach would be to split it out into a standalone Node module, Gimmea (as in, 'Give me a').
Check it out at npmjs.com for examples on how to use it.
