PureMVC is a software framework for creating applications based on the well-established model–view–controller (MVC) design pattern. It was originally implemented in the ActionScript 3 language for use with Adobe Flex, Flash, and AIR, and it has since been ported to nearly all major web development platforms. It is free and open-source software released under a BSD 3-clause license.

Implementations

Standard version

The Model, View and Controller application tiers are represented by three Singletons (a class of which only one instance may be created).

The MVC Singletons maintain named caches of Proxies, Mediators and Commands, respectively. The Facade, also a Singleton, provides a single interface for communications throughout the application. These four Singletons are referred to as the Core Actors.

• Data objects, be they local or remote, are managed by Proxies.
• The View Components that make up the User Interface are managed by Mediators.
• Commands may interact with Proxies, Mediators, as well as trigger or execute other Commands.

All actors discover and communicate with each other via the Facade, rather than work directly with Model, View and Controller.

PureMVC also introduces a Publish/subscribe-style Observer notification scheme. This allows asynchronous, event-driven communications between the actors of the system, and also promotes a loose coupling between those actors, since the subscriber never needs to have direct knowledge of the publisher.

The Standard Version Reference Implementation is written in ActionScript 3.

MultiCore version

This variant supports modular programming, allowing the use of independent program modules each with their own independent PureMVC 'Core'. A Core is a set of the four main actors used in the Standard framework (Model, View, Controller, and Facade). This version of the framework uses Multitons instead of Singletons. Rather than storing one instance of the class, a Multiton stores a map of instances. Each Core is referenced by an associated Multiton Key.

The MultiCore Version of the framework was developed due to the widespread need for modular support for the movement toward ever-more ambitious Rich Internet Applications which must load and unload large pieces of function at runtime. For instance a PDA application might need to dynamically load and unload modules to manage task list, calendar, email, contacts, and files. The multicore version facilitates unit testing.

The MultiCore Version Reference Implementation is written in ActionScript 3.

Ports

There are several active PureMVC ports—implementations for various programming languages, each contributed and supported by PureMVC community members. Each port, in turn supports one or more target development platforms, which cover most major mobile, browser, desktop and server environments.
