A bundle in Symfony (and eZ Platform) is a separate part of your application that implements a feature. You can create bundles yourself or make use of available open-source bundles. You can also reuse the bundles you create in other projects or share them with the community.

Many eZ Platform functionalities are provided through separate bundles included in the installation. You can see the bundles that are automatically installed with eZ Platform in composer.json.

Working with bundles

All bundles containing built-in eZ Platform functionalities are installed automatically. Additionally, you can install community-developed bundles from eZ Platform Packages.

To learn how to create your own bundles, see Symfony documentation on bundles.

Overriding third-party bundles

When you use an external bundle, you can override its parts, such as templates, controllers, etc. To do so, make use of Symfony's bundle override mechanism. Note that when overriding files, the path inside your application has to correspond to the path inside the bundle.

Removing bundles

To remove a bundle (either one you created yourself, or an out-of-the-box one that you do not need), see the How to Remove a Bundle instruction in Symfony doc.
