New and Noteworthy Since Vaadin 24.0

Notable Changes

Gradle support is raised to the version (Gradle 7.6) required by jackson

Flow

• Pre-compiled frontend bundle for production builds
  • Vaadin uses a pre-compiled frontend bundle enabling building Vaadin Flow projects for production more quickly without installing Node.js and npm dependencies. This is an extension of frontend dev bundle feature, introduced in Vaadin 24.0, but for production builds.
• Production Bundle Loading Optimizations
  • A production build scans for Routes and lazy loads the components used in the routes when navigated.
  • documentation
• Hot Module Redeployment
  • Allows changing styles immediately without page reload
    see release note for all features

Hilla

• Hilla Gradle Plugin documentation

Design System

• New SideNav component (released under feature flag)
  • If you have a project using vcf-nav it is recommended to migrate to vaadin-side-nav.
• New Map features
  • Styleable label for markers documentation
  • Drag and drop markers documentation
• Warning color in Lumo theme
• Warning Notification theme variant
• Accessibility improvements
  • Flow component APIs for setting aria-label and aria-labelledby
  • Optional borders around input fields
• TreeGrid hierarchical scrollToIndex
  • This is a behavior altering change. Previously the tree grid would try to scroll to the effective row index, counting children of expanded nodes, which was not reliable due to lazy loading. The new scrollToIndex(int rowIndex) implementation will only scroll to the index of a row in the root level of the tree. A new overload scrollToIndex(int... indexes) allows to scroll to a nested item in the tree by specifying the row indexes for each level through the tree.

Kits

• Observability Kit now includes Frontend Observability to instrument client-side code and collect traces from the browser
• Obserability Kit has now support for Hilla apps with a new Java starter module and a client-side library
• SSO Kit gets its own client-side libraries for both Lit and React when used in Hilla apps
• SSO Kit now provides an API to require authentication for specific route for both Vaadin and React routers

Classic Components

• The rendering performance of the Classic GridLayout has been enhanced for large/huge grids.
