It seems that everybody's written something similar. My entry is Slinky (http://github.com/mwylde/slinky http://github.com/mwylde/slinky) which in addition to an auto-compiling web/proxy server also includes a build tool with dependency resolution and minification for scripts and css. It's in Ruby instead of Node and is a bit less opinionated about how a project should look like. I wrote it when I became frustrated with the options for writing rich client apps in compiled languages (HAML/SASS/CoffeeScript). It's so convenient to be able to cd to a directory and do "slinky start" and have a static file server running.
