2.1.0

Website · Getting Started · Documentation

The Hilla 2.1 minor release adds Gradle support, several enhancements to the UI components library, and a new Observability Kit to facilitate monitoring and troubleshooting Hilla applications running in production. This release also includes enhancements to the development experience.

New and Noteworthy since Hilla 2.0

• Support for building applications with Gradle with the new Hilla Gradle Plugin
• React API for the <TabSheet/> and <MultiSelectComboBox/> UI components
• React components support importing without the .js file extension
• Frontend scaffolding goal in build plugins (hilla:init-app for Maven and hillaInitApp for Gradle) that helps starting development from a bare Java application
• Observability Kit supports Hilla applications
• Client-side library that simplifies working with the SSO Kit

Known Issues

• TypeScript error: An import path can only end with a '.ts' extension when 'allowImportingTsExtensions' is enabled. Here are the ways to mitigate it depending on the cause location:
  • For imports in your application, use .js or extension-less paths.
  • For the @vaadin-component-factory/vcf-nav component, make sure to use the latest version in package.json, and consider migrating to @vaadin/side-nav.
  • For the imports not under your control, you can suppress the error by specifying "allowImportingTsExtensions": true in tsconfig.json.
