INTRODUCTION

PageBus

PageBus is an open-source Javascript messaging bus for integrating heterogenous AJAX elements in a web page through broadcasting and listening of events published to specific topic names. Messages can be dispatched from one AJAX component to another, or they can be bridged with messaging systems on the remote server.

Rather than hard-wiring the AJAX components on a page to talk to one another, PageBus simplifies development by providing a simple publish-subscribe API. This helps modularize applications and promotes team development, unit testing, and better source repository management.

The PageBus class can be use to publish objects to any topic and have other (decoupled) components subscribe to these topics. It is a powerful mechanism for inter component communication and state management.
