PureMVC for node.js

Modification of the multicore javascript port for use in a node.js environment.

This is the master repository of the npm npmvc module.

The main goal of this module is to add more flexibility and modulairity within the use of the combination of Node.js and the PureMVC framework. The module enables the aggregation of PureMVC classes in a local file structure or/and in seperated modules.

It adds an include method on top of the official multicore PureMVC JavaScript library (currently version 1.0.1). This method is based on the node.js require method and is added to the puremvc namespace. (See API specs below).

You can use the include function to include dependecies that are located local or in other npm modules. Class files are wrapped the node.js module.export style (see Creating external class files).

Current versions

  • 1.0.6 (latest)
  • 1.0.6-rc3
  • 1.0.5 (stable)


npm install npmvc

setup a puremvc project in node.js

When installed you can use it like this

var puremvc = require("npmvc");
// make instance of ApplicationFacade and trigger start command 
var app = test.ApplicationFacade.getInstance(test.ApplicationFacade.NAME);

Creating external class files

module.exports = function(include,puremvc) {
// use include te aquire dependency class files 
// ---> now you can use puremvc.define to define class 
 * @class test.ApplicationFacade
 * @extends puremvc.Facade
        name: 'test.ApplicationFacade',
        parent: puremvc.Facade
         * @method start
         * @return {[type]} [description]
        start: function() {
            this.registerCommand("START", test.controller.StartCommand);
            this.sendNotification("START", {});
         * Retrieve an instance of ApplicationFacade. 
         * If one has not yet been
         * instantiated, one will be created for you.
         * @static
         * @param {string} multitonKey 
         * @return test.ApplicationFacade
        getInstance: function(multitonKey) {
            var instanceMap = puremvc.Facade.instanceMap;
            instance = instanceMap[multitonKey]; // read from the instance map 
            if (instance) // if there is an instance... 
                return instance; // return it 
            return instanceMap[multitonKey] = new test.ApplicationFacade(multitonKey);
         * @static
         * @type {string}
        NAME: 'test.ApplicationFacade'

Extra methods:

This module adds some exra methods on top of the puremvc root object:


path [string] Sets the source dir for all include's, It uses this for includes on all directory levels. So when you include a dependencie in say model/MyProxy you have to reference model/vo/MyVo by using the path up from the sourceDir, not relative to the folder the file is in:


If you have to hack this, you can use tempPath, the second param of puremvc.include. See below.

Also note that if you do not set the sourceDir it will default to process.cwd() (the directory where you started the main node file).

puremvc.include(path:String, tempPath:String, callback:function):*

Returns any value, but mainly use for return the reference to the classlets constructor from puremvc.define.

path [string]

Path to puremvc class, relative from path set by puremvc.setSourceDir

tempPath [String] This overides the sourceDir. An include of MyVo in class model/vo/MyVo would look like this:


callback [function] You can use a callback, but you have to trigger it in the aquired class file.

You can include a class in an other npm module if the file is not equal in the context of your current sourceDir path. So when you want to load the class SomeClass in the module my-npm-module then do not use tempPath but use:



returns the current source directory, root of puremvc classes.

Creating npm modules

This is one way to create puremvc modules that harmonize with npm (node package manager).

in package.json add a puremvc object, and provide a namespace, sourcedir (relative from module root dir), and an array with initial includes. The main property has to point to 'index.js'.

  "name": "somemodule",
  "version": "1.0.0",
  "description": "Just a module",
  "main": "index",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  "author": "",
  "license": "ISC"

for index.js use this code:

module.exports = function(include,puremvc) {

Now in any point in your npmvc application you can import a module by using the include method:

module.exports = function(include,puremvc) {
        // CLASS INFO 
            name: 'com.domain.command.RunCommand',
            parent: puremvc.SimpleCommand
            execute: function() {
                var mediator = new com.domain.somemodule.mediator.SomeMediator();

Extra options:


boolean (default:false)

This option only works on macosx darwin. In a case insensitive environment typo's can be hard to find because node.js on a mac does not throw an error when loading case typo's in filenames. When validateIncludePaths is set to true it will warn when a file that is included has a case typo in it's path.

Note that in a other environment than 'darwin', npmvc will ignore this option and outputs a warning about that when set to 'true'.

Set this option before calling the include method. Example usage:

var puremvc = require("npmvc");
puremvc.validateIncludePaths = true;


boolean (default:true)

This option only works on macosx darwin. It suppresses throwing case insensitive errors. It is mainly for testing, so you can ignore it basicly.
