Bundles

A bundle is Serenade’s unit of reusable, in-process application composition. It can declare dependencies on other bundles and participate in the kernel lifecycle.

Bundles can contribute services, package configuration, routes, event subscribers, and console commands through the framework’s extension points. The kernel orders bundles by their declared dependencies before build and boot; shutdown happens in reverse dependency order.

The canonical demo-app pairs DemoBundle with FrameworkBundle. It is a runnable reference, not a required application template.

For implementation details, dependency rules, extensions, and the public API boundary, read the bundle extensions guide.
