Lazorse is a connect middleware stack with a strong emphasis on extensibility that routes requests, coerces parameters, dispatches to handlers, and renders a response. It borrows heavily from other awesome nodejs web frameworks but with a couple of twists designed to make writing machine-consumable ReSTful APIs a little easier. Because it's all "just middleware", you can also pull out and re-arrange the various pieces to better suit the needs of your application.
What's the deal with the name?
While it could be viewed as a portmentaeu of Lazy and Resource, I prefer to think of it as horses with lasers.
