What are bundles in Symfony?

Symfony bundle are very similar to plugins or packages in other frameworks or CMS. In Symfony, everything is a bundle from core framework components to code you write.The bundle gives the flexibility to use pre-built features packaged in third-party bundles or to create and distribute your own bundles.

There are two types of bundles are available in Symfony:

• Application-specific bundles: only used to build your application.
• Reusable bundles: meant to be shared across many projects.
