# Backbone.Marionette TodoMVC app
[Backbone.Marionette](http://marionettejs.com) is a composite application library for Backbone.js that aims to simplify the construction of large scale JavaScript applications. It is a collection of common design and implementation patterns found in the applications that Derick Bailey has been building with Backbone, and includes various pieces inspired by composite application architectures, such as Microsoft's "Prism" framework.
[Backbone.Marionette](http://marionettejs.com) is a composite
application library for Backbone.js that aims to simplify
the construction of large scale JavaScript applications.
It is a collection of common design and implementation patterns
found in the applications that I (Derick Bailey) have been building
with Backbone, and includes various pieces inspired by composite
application architectures, such as Microsoft's "Prism" framework.
This implementation of the application uses Marionette's module system. Variations using RequireJS and a more classic approach to JavaScript modules are also [available](https://github.com/marionettejs/backbone.marionette/wiki/Projects-and-websites-using-marionette).
## Key Benefits
* Scale applications out with modular, event driven architecture
* Sensible defaults, such as using Underscore templates for view rendering
* Easy to modify to make it work with your applicaton's specific needs
* Reduce boilerplate for views, with specialized view types
* Build on a modular architecture with an Application and modules that attach to it
* Compose your application's visuals at runtime, with Region and Layout
* Nested views and layouts within visual regions
* Built-in memory management and zombie killing in views, regions and layouts
* Built-in event clean up with the EventBinder
* Event-driven architecture with the EventAggregator
* Flexible, "as-needed" architecture allowing you to pick and choose what you need
* And much, much more
This implementation of the application uses Marionette's module system.
