Marionette 4 is now available! See our
upgrade notes for the differences between
v3 and v4. Please let us know if you encounter any issues so we can resolve

About Marionette

Marionette 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
applications.

Backbone provides a great set of building blocks for our JavaScript
applications. It gives us the core constructs that are needed to build
small apps, organize jQuery DOM events, or create single page apps that
support mobile devices and large scale enterprise needs. But Backbone is
not a complete framework. It's a set of building blocks. It leaves
much of the application design, architecture and scalability to the
developer, including memory management, view management, and more.

Marionette brings an application architecture to Backbone, along with
built in view management and memory management. It's designed to be a
lightweight and flexible library of tools that sits on top of Backbone,
providing the framework for building a scalable application.

Like Backbone itself, you're not required to use all of Marionette just
because you want to use some of it. You can pick and choose which features
you want to use. This allows you to work with other Backbone
frameworks and plugins easily. It also means that you are not required
to engage in an all-or-nothing migration to begin using Marionette.

We're happy to discuss design patterns and learn how you're using Marionette.

* Scalable: applications built in modules with event-driven architecture
* Sensible defaults: Underscore templates are used for view rendering
* Easily modifiable: works with the specific needs of your application
* Reduce boilerplate: for all views, including specialized types
* Create: application visuals at runtime with Region and View objects
* Nested: Views and CollectionViews within visual regions
* Built-in: memory management and zombie-killing for Views, CollectionViewsa and Regions
* Event-driven architecture: utilizing Backbone.Radio
* Flexible: "as-needed" architecture allowing you to pick and choose what you need
* And much, much more
