Dojo JavaScript framework

Introduces the Dojo JavaScript framework used for the user interface in Optimizely Content Management System (CMS).

Optimizely Content Management System (CMS) uses the Dojo Toolkit as the JavaScript framework on which client-side development is done.

The Dojo toolkit is a client-side framework for building rich internet applications hosted in a web browser. Dojo is an open-source framework that helps speed up the development of cross-platform rich internet applications by giving you a lot of features. Some key features include:

  • Rich UI widgets using the Dijit widget system
  • Asynchronous communication
  • Class declaration and modular development
  • Desktop and mobile support

The Dojo Toolkit consists of three main components:

ComponentDescription
dojoThe core API of the framework and contains features for DOM manipulation, class declaration, event listening, message publishing and subscription, and asynchronous requests and processing.
dijitThe user interface system built on top of the Dojo core. Its primary feature is the widget system which is used to manage and manipulate visual elements in a modular manner.
dojoxA collection of sub-projects built on top of the Dojo core. This can be considered a repository of Dojo plugins or a testing ground for new features that will in future be part of the Dojo or Dijit namespace.

Dojo has a selection of tutorials, blogs and other resources that help new developers come up-to-speed with the framework.
