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.
