What's new in JavaScriptMVC Lately

The following is a quick overview of what's going on with JMVC since 3.0:


$.Model and $.View both support deferreds. Allowing super sexy code like:

$('#recipes').html('recipes.tmpl', Recipe.findAll() );


Classes are used to simplify JavaScript constructor creation. Both $.Controller and $.Model extend $.Class.

$.Class $.Class([name,] [classProperties,] [prototypeProperties])

To create a Class class of your own, call $.Class.extend with the:

  • name of the class which can be used for introspection,
  • classProperties that are attached directly to the constructor, and

You need a client-side dependency management and build system.

You need a client-side dependency management and build system. What I mean by this is:

A client-side script loader that does dependency management and can package your scripts for rapid download.

There are only 2 that I'm aware of that qualify are RequireJS and StealJS. There are 3 reason to use these systems:

  • Easy, Parallel, Isolated Development
  • Integrated Build Systems
  • They work on every system

var my$ = function(selector){
if(!(this instanceof my$)){
return new my$(selector);
if(typeof selector === 'string'){
var arrayOfElements = my$.makeArray( document.querySelectorAll(selector) );

$.fixture("/searchresults", function(options){
var countries = [{

Enums in JavaScript

Reasons to Use Enums:

  1. Easier to Debug / more likely to give errors.
  2. Can look up available properties.
  3. Property values changes.

Lets break each of these down:

There's so many things wrong with the world of script loading today. I want an easy way to:

  • install locally scripts and their dependencies
  • load these scripts from my application

I want it to:

  • work readily with almost all existing projects, source that does not use the script loader
  • handle versioning
  • have as few configs as possible
You can’t perform that action at this time.
