Hilla 24.7.0.beta1

Website · Getting Started · Documentation

This is a pre-release for the next minor version of Hilla. We appreciate it if you give it a try and report any issues you notice.

Behavior Altering Changes

• TypeScript generation in Hilla now uses Spring to discover @BrowserCallable and @Endpoint classes instead using a separate classpath scan. #2616

  Previously, Hilla used its own classpath scanning with a dedicated build configuration. To avoid duplicate classpath specifications—one for Spring and another in the build—and to improve generator reliability, we now use only Spring’s configuration. This also eliminates the extra build tool execution previously required to extract classpath information.

  With this change, only Spring-managed beans are eligible as browser-callable services. While this was already common practice, it’s now explicitly required. If a browser-callable service is defined in a dependency or another package, it must be included in Spring’s component scan to be recognized.

  Note: Support for custom Hilla plugin classpath configuration has been dropped. If your project previously relied on it, update your setup accordingly.
