Private class methods using the commonjs module system

gistfile1.js

// ----- throw your class into one single file = a seperate scope

// constructor and export
var myClass = module.exports = function () {
    // ..
}

// a public method
myClass.prototype.publicMethod = function () {

    // can have access to the private method
    privateMethod.apply(this);
}

// a private method
var privateMethod = function () {}



// ------ access the class from another file
var myClass = require('theabove.js');

// create new instance
var instance = new myClass();

// this will work
instance.publicMethod();

// this will fail
instance.privateMethod();
