Function for walking over files in node are requiring them. Great for loading groups of objects such as routes, models, etc.

walk.js

var walk = function(path) {
    fs.readdirSync(path).forEach(function(file) {
        var newPath = path + '/' + file;
        var stat = fs.statSync(newPath);
        if (stat.isFile()) {
            if (/(.*)\.(js$|coffee$)/.test(file)) {
                require(newPath);
            }
        } else if (stat.isDirectory()) {
            walk(newPath);
        }
    });
};
