Nodejs submodules lazyloading, could be very useful for private modules repos

nodejs_lazyloading

// Nodejs submodules lazyloading, very useful for private modules repos
// where you don't want to create separate repo for evey module
// using this snippet, you can create one main repo for private modules
// and create submodules inside subfolder with the same name.
var fs = require('fs');

exports.answer = 42; // Some existing property

// This is how you would do it without lazy loading
// basically u would need to require every submodule right away
// even if you don't need it right away
//
// exports.sub1 = require('./submodules/sub1');


// This is where lazyloading magic for nodejs happens
fs.readdirSync(__dirname + '/submodules').forEach(function (plugin) {

  plugin = plugin.replace('.js', '');

  // __defineGetter__ is a getter method which will be called if particluar
  // property (or submodule in our case) will be requested
  exports.__defineGetter__(plugin, function () {

    return require('./submodules/' + plugin);

  });

});
