Super-tiny recursive directory list in nodejs, if you don't care that you're using sync functions.

gistfile1.js

var fs = require('fs');

function ls(dirname){
  return [].concat.apply([], fs.readdirSync(dirname).sort().map(function(f){
    f = dirname + '/' + f
    return fs.statSync(f).isDirectory() ? ls(f) : f
  }));
}
