Introduction to Dojo
Episerver 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:
| Component | Description |
|---|---|
| dojo | The core API of the framework and contains features for DOM manipulation, class declaration, event listening, message publishing and subscription, and asynchronous requests and processing. |
| dijit | The 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. |
| dojox | A 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. |
