solving circular dependency in node using requirejs

I have been try out many suggestions I found googling for circular dependency in node and requirejs. Unfortunately, I\'m not getting it to work. The try which is closed to a

Circular references are fine and not necessarily a symptom of bad design. You might argue that having many tiny modules could be equally detrimental because code/logic is scattered.

To avoid the dreaded TypeError: Object #<Object> has no method you need to take some care in how you initialize module.exports. I'm sure something similar applies when using requirejs in node, but I haven't used requirejs in node.

The problem is caused by node having an empty reference for the module. It is easily fixed by assigning a value to the exports before you call require.

function ModuleA() {
}

module.exports = ModuleA;  // before you call require the export is initialized

var moduleB = require('./b');  //now b.js can safely include ModuleA

ModuleA.hello = function () {
  console.log('hello!');
};
