Easily extend capabilities

Aura Extensions help you extend the core capabilities of your app
before any of your components load. Want to ensure all of them have
access to a particular library, like Backbone, or an API wrapper, like GitHub?

It'll make them available via the component's sandbox so you don't have
to worry about importing and setting this up yourself.

The Aura Mediator supports global and sandboxed event messaging. These allow components to communicate with each other by subscribing, unsubscribing and emitting event notifications. Namespaces, wildcards and more are supported.
