I try to require sub-directories from a node module without success.

/moduleA
  index.js
    require('coffee-script/register')
    require('./src')
    
  extensions.js
    require('coffee-script/register')
    require('./src/extensions')
  
  /src
    index.coffee
      # This is what I want to achieve in a very simplified form
      # It would actually be on a class representing the module
      # and the modules need to be loaded on `init` so I can set
      # up some listeners and such
      exports.loadExtensions = (name) ->
        require "#{name}/extensions"
    
    /extensions
      index.coffee
        # requires all extensions in this folder
        exports.extensionA = require './extensionA'
        exports.extensionB = require './extensionB'
      extensionA.coffee
      extensionB.coffee
      
/moduleB
  index.js
    require('moduleA'); // works
    require('moduleA/extensions'); // worksn't
    
    // This is what needs to work. In the actual code it won't appear like this,
    // but rather tucked away in an init instance method.
    require('moduleA').loadExtensions('moduleA');
