Brew

Brew is Kona’s reactive server-component layer. You write Kotlin or Java classes with public state and actions, render HTML with Crema, and Brew keeps the browser in sync over a small JSON protocol—without a full page reload.

Brew ships as a separate artifact (org.konaframework:kona-brew) from the kona-brew repository. Scaffold with kona new my-app --kit=brew, or add the dependency next to your other Kona modules.
