Marionette.js is a composite application framework built on top of Backbone.js that provides application architecture, view management, and memory management for large-scale JavaScript single-page applications. This repository (backbone.marionette) is in maintenance mode, with new feature development moved to the Backbone-free 'marionette' library.

Use cases

• structure a large backbone single-page application
• add view and memory management to backbone apps
• organize complex layouts from small views
• decouple communication between app components
• gradually add architecture to an unruly legacy backbone codebase
• share UI behaviors across views as mixins

When to choose

• you maintain an existing Backbone.js application that needs structure
• you want a lightweight, pick-and-choose architecture layer over Backbone
• you need battle-tested view lifecycle and region management

When to avoid

• you are starting a new frontend project from scratch
• you want a modern component-based framework like React or Vue
• you need active feature development, since this repo only receives fixes
