Javascript - Definitive Module Pattern

http://inniepress.blogspot.com/2014/07/definitive-module-pattern.html

The Javascript "Definitive Module Pattern" is an alternative to the "Module Pattern" and the "Revealing Module Pattern". It offers the following advantages: declaratively namespaces the private and public functions, decouples the public functions from the return statement, groups all functions within object literals, and offers configurable pubic scopes (or polyscopes).

Module Pattern

var module = (function () {

    // private
    var private_one = function () {};
    var private_two = function () {};

    // public
    return {
        public_one: function () {
            private_one();
        },
        public_two: function () {
            private_two();
        }
    };

})();

Revealing Module Pattern

var module = (function () {

    // private
    var private_one = function () {};
    var private_two = function () {};

    // public
    return {
        public_one: private_one,
        public_two: private_two
    };

})();

Definitive Module Pattern

var module = (function () {

    // private
    var _private = {
        private_one: function () {},
        private_two: function () {}
    };

    // public
    var _public = {
        public_one: _private.private_one,
        public_two: _private.private_two
    };

    return _public;

})();

Definitive Module Pattern (CoffeeScript version)

module = (->

    // private
    _private =
        private_one: ->
        
        private_two: ->
        

    // public
    _public =
        public_one: _private.private_one
        public_two: _private.private_two

    _public
)()

Definitive Module Pattern (CommonJS version)

var module = (function () {

    // private
    var _private = {
        private_one: function () {},
        private_two: function () {}
    };

    // public
    var _public = {
        public_one: _private.private_one,
        public_two: _private.private_two
    };

    return _public;

})();

module.exports = module;

Definitive Module Pattern (configurable public scopes)

var module = (function () {

    // private
    var _private = {
        private_one: function () {},
        private_two: function () {}
    };

    // public (set 1)
    var _public1 = {
        public_one: _private.private_one,
        public_two: _private.private_two
    };

    // public (set 2)
    var _public2 = {
        public_one: _private.private_one,
        public_two: _private.private_two
    };

    // configurable public scopes
    var _publics = [_public1, _public2];

    return _publics;

})();
