A Joomla! extension is anything that extends Joomla!’s functionality beyond the core. There are three main types of extension: components, modules, and plugins.
To view the extension directory, visit http://extensions.joomla.org/extensions/
- Modules – Typically make up the elements of a sidebar or content menus. Modules complement the content contained in a component; they are not intended to be the main substance of a page.
- Components – Frequently have sophisticated back-end controls. The back-end is commonly used to create and update records in database tables. A simple example would be a small guest book or a simple banner manager where the user has controls from which they can use the functionality of the component .
- Languages – Joomla! has multilingual support, which enables us to present Joomla! in many different languages. Language extensions include files that define translated strings for different parts of Joomla!.
- Templates – We use templates to modify the general appearance of Joomla!. There are two types of template extension: site templates and admin templates.
- Tools – Although referred to as extensions, tools are very different to components, modules, and plugins. The term ‘tools’ is used to describe any other type extension that can be used in conjunction with Joomla!.
The top – Extensions layer, consists of Extensions to the Joomla Framework and its applications:
Modules , Components , Templates.
The middle – Application layer, consists of applications that extend the Framework JApplication class. Currently there are four applications included in the Joomla distribution:
- JInstallation is responsible for installing Joomla on a web server and is deleted after the installation procedure has been completed.
- JAdministrator is responsible for the back-end Administrator.
- JSite is responsible for the front-end of the website.
- XML-RPC supports remote administration of the Joomla website.
The bottom – Framework layer, consists of:
- The Joomla Framework itself.
- Libraries that are required by the Framework or are installed for use by third-party developers.
- Plugins extend the functionality available in the Framework.
