Export the result of a function in node.js

Question

Export the result of a function in node.js

I have written this function. What it does is reading recursively all the files into a folder thanks to nodejs module recursive-readdir. It works well. The problem is I don't know how to export outside routes array by using module.exports. I have tried to put it outside the callback function, inside but the variable is undefined. Any idea?

var path = require('path');
var recursive = require('recursive-readdir');

recursive(__dirname, function(err, files){

  var routes = {};

  for (var i = 0, dim = files.length; i < dim; i++) {
    var file = path.basename(files[i], '.js');
    if(file !== 'bootstrap'){
      routes[file] = require(files[i]);
    }
  }
});

var path = require('path');
var recursive = require('recursive-readdir');

module.exports = function getRoutes(callback) {
     recursive(__dirname, function(err, files){

         var routes = {};

         for (var i = 0, dim = files.length; i < dim; i++) {
             var file = path.basename(files[i], '.js');
             if(file !== 'bootstrap'){
                 routes[file] = require(files[i]);
             }
         }

         if (callback) { callback(routes); }
});

you can now use it like this

require('get_routes')(function(routes) { ... });

.

if you want more expressive way you may want to do

module.exports.find = function (callback) { ... }

then outside use

var routes = require('routes')
routes.find(function (routes) {...});
