Exoskeleton

Exoskeleton is a faster and leaner Backbone for your HTML5 apps.

http://exosjs.com

What already works

All features you need for real-world app are working. All software tests are passing: (libs = underscore and jquery)

• Backbone: with and without libs
• Chaplin: with and without libs

Marionette and other popular plugins: WIP.

Building

Default and custom builds:

make # Will create exoskeleton.js
make noutils # If you want to use Underscore and jQuery
             # and don't want to include `Exoskeleton.utils`.
make min     # Minified version.
# Custom, like this:
cat lib/{header,events,collection,sync,history,footer}.js > exoskeleton.js

Features

• Custom builds
• No hard dependencies on underscore or jquery
• Support for Bower and Component(1)
• AMD support
• Speed: blazing fast when used without jQuery.

Also:

• Router with query string support
• View#delegateEvents has keepOld option that allows to preserve old events.
• All params are allowed for model attributes, for example model.get('constructor') (jashkenas/backbone#1495)
• Ultra-fast event delegation via native utils.delegate method.
• Native View#find and View#findAll DOM search methods.
• Event triggering on disposed objects is 20 times faster
• Backbone.Deferred overridable method for custom promise libraries or DOM promises

Differences

• When jQuery is not used, you must use event.delegateTarget instead of event.currentTarget for event delegation. This is because currentTarget is not overridable on native non-jQuery events.

• Declaratively defined view events which point to non-existing handler functions are no longer tolerated / skipped. Early error is thrown instead.

• In no-underscore environment, there are no underscore-inspired Collection methods (each, pluck etc.), but there are ES5-inspired methods:

  forEach, map, filter, some, every, reduce, reduceRight, indexOf, lastIndexOf

  Also, no underscore-inspired Model methods at all.

• emulateHTTP and emulateJSON were removed

Changelog
