About Marionette.Toolkit

Marionette.Toolkit is a collection of opinionated extensions for Marionette Each element helps to reduce boilerplate for complex large scale application problems. This toolkit was built from scripts open sourced from


App - An extension of Marionette.Application. Its purpose is to provide an object with a initialize/start/stop/destroy lifecycle.

Component - An extension of Marionette.Application. Provides a consistent interface for which to package state-view-logic.

Async App start - How to easily start apps asynchronously.

StateMixin - JavaScript Object with a Backbone.Model for keeping state. Used by both the App and Component but can be applied to any Marionette Class.

ChildAppsMixin - Functionality to add or remove child Apps to a parent App, start apps asynchronously, and connect the child App lifecycle with the parent App lifecycle.

EventListenersMixin - Binds events to the App while running and removed (and only those) when the App is stopped.

ViewEventsMixin - Adds Marionette.View-like support for view event proxying. The API is analogous to childViewEventPrefix, childViewEvents and childViewTriggers.
