Node.JS static file web server. Put it in your path to fire up servers in any directory, takes an optional port argument.
var http = require("http"),

path.exists is now called fs.exists

This is insecure, someone can request /../../../etc/shadow or similar to read any file they want.

I guess you're not familiar with how path.join works, because as coded here it won't resolve to a directory outside of cwd directory branch.

fs.exists is deprecated. fs.statSync can be used to check if file path exists, as in dkebler's code above.
