Arrays break it

I tried to enable hotswap for every module (patching it), to see if it works in a real project.

I didn't test the reloading. Just tried to run it.

The app died with undefined is not a function somewhere deep in the modules (under node_modules).

I tried to move require('hotswap') lower in the code, to exclude some modules, so the server actually started running, but then there was another error of the same kind.

To give a glimpse of what's happening:

undefined is not a function

   at Object.<anonymous> (/js/javascript-nodejs/node_modules/image-size/lib/detector.js:7:7)
   at Module._compile (module.js:460:26)
   at extension_js (/js/javascript-nodejs/node_modules/hotswap/hotswap.js:220:10)
   at Module.load (module.js:355:32)
   at Function.Module._load (module.js:310:12)
   at Module.require (module.js:365:17)
   at require (module.js:384:17)
   at Object.<anonymous> (/js/javascript-nodejs/node_modules/image-size/lib/index.js:7:16)

And here I paste the code from the image-size module (from npm):

'use strict';

var typeMap = {};
var types = require('./types');

// load all available handlers
types.forEach(function (type) {
  typeMap[type] = require('./types/' + type).detect;
});

module.exports = function (buffer, filepath) {
  var type, result;
  for (type in typeMap) {
    result = typeMap[type](buffer, filepath);
    if (result) {
      return type;
    }
  }
};

Looks like the reason why doesn't work is types being an array.

I think you could try reload a json file not a js file since the array.
