In Joomla Component Builder (JCB), a Joomla Component is the top-level unit that brings everything together.
It acts as the central container — compiling all attached entities and logic into a complete, versioned, installable Joomla extension.
A Component includes:
- Admin Views (core data tables with fields and ACLs)
- Site Views (frontend output)
- Custom Admin Views (customized backend interfaces)
- Modules & Plugins (packaged alongside)
- Custom Code (injectable and reusable)
- Files and Folders (media, scripts, assets)
- MySQL Tweaks & Schema Updates
- PHP Helper Classes
- Component Configurations (global parameters)
- Placeholders & Overrides
- Dynamic Dashboards (overview screens)
- Routing Setup (site and admin)
- Version Definitions (Joomla 3, 4, 5 support)
- README, Wikis & Docs (optional, for internal reference)
Every entity you build in JCB is ultimately assembled into one or more Joomla Components — which are then compiled into installable packages, ready for use or distribution.
Components control the following:
- Which views, modules, plugins, and helpers are packaged
- How the database is initialized or migrated (via tweaks)
- Where assets are placed in the Joomla filesystem
- Which version of Joomla the output is compatible with
- How the component is installed, updated, and distributed
- What language files, readmes, and wikis are bundled
- Who authored the component and where it lives in Git
Components are the single point of truth for defining your extension. Once everything else is configured — fields, views, snippets, layouts — you bind them all together through the Component.
JCB Components support:
- Branch-specific configuration (Joomla 3, 4, 5)
- Component-level versioning and changelogs
- Resetting from a central repository
- Forking to maintain your own variants
- Pushing updates upstream or into shared team forks
They can also be extended via init/reset/update workflows, just like all other JCB entities.
This makes them ideal for distributed teams, client-specific forks, and open-source extension development.
A Component in JCB isn't just a bundle of files — it's a fully-defined application package that carries the design, data, logic, and behaviour of your Joomla extension.
