What is a Joomla! Component?

Most components have two main parts: an administrator part and a site part. The site part is what is used to render pages when being called during normal site operation. The administrator part provides an interface to configure and manage different aspects of the component and is accessible through the Joomla! administrator application.

Joomla! comes with a number of core components, like the content management system and contact forms.

Intro to Component Development

There are many articles, tutorials, references and FAQs which focus on component development. If this is your first time developing a component for Joomla, you should start with the Absolute Basics of How a Component Functions. If needed, you can visualise the control flow of a component with these diagrams.

Next, you will want to read our   MVC tutorial  →  Developing a Model-View-Controller Component. Remember to familiarise yourself with Joomla! Secure coding guidelines and Development Best Practices.

Once you have read the tutorial and/or tried the example component, you can focus more on the specifics of your component with additional articles. These are listed on the Component Development Portal or any of the supporting Portals for Development(Plugins, Modules or Templates).
