Vaadin Flow 9.0.0.beta1

Changes in Flow from 9.0.0.alpha11

• New Features:

  • ⧉ Add HasAriaLabel and implement it on html components that support it. PR:12126

• Fixes:

  • ⧉ Show rejected promise errors in the debug window. PR:12156

  • ⧉ Improve log output when starting a dev server. PR:12163

  • ⧉ Make Java resource folder available in application configuration. PR:12164

  • ⧉ Do not create constant pool key eagerly. PR:12124

    Stops creating a constant pool key eagerly as it was being created 11 times for a simple click listener after each event data expression was evaluated. The change improves the server side roundtrip processing time for 2000 buttons with click listeners from roughly 210ms to 130ms (-40%) by not eagerly creating the id using MessageDigest after evaluating each event data expression. Difference to buttons without any click listeners is still about x2 (65ms->130ms). Closes #7826

  • ⧉ Move client side frontend resources to META-INF/frontend. PR:12128. Ticket:11057

  • ⧉ Stop showing message start in error. PR:12013

    Stops outputting the rpc message content's first 1000 characters in the error message, that could end up even visible in the UI. Instead only a part of the message details are output as debug-level log.

  • ⧉ Poll dev server status using fetch so that the spinner keeps spinning. PR:12112

    As server for status instead of reloading the whole page.

  • ⧉ Remove 'target/' prefix for fusion form version check. PR:12110

    Remove the target/ prefix for checking the legacy version of fusion form so that it also works with Gradle which uses build instead target for the output folder.

• New Features and Fixes for expermental Vite based frontend build (behind a feature flag):

  • ⧉ Enable livereload for theme. PR:12138. Ticket:12113

    Enables live update of custom theme when files change during execution. Also handles situations where files are added to theme.

  • ⧉ Vite production bundling. PR:12142

    Run vite build in prod mode with bundles going to target/classes/META-INF/VAADIN/webapp If there is no features file disable all features (otherwise multi-module projects will inherit setting of previous projects in build-frontend)

  • ⧉ Support custom theme with vite. PR:12111. Ticket:12058

  • ⧉ Allow passing Vite options using devmode.vite.options. PR:12118

  • ⧉ Use correct URL in Vite status check so that a server is re-used. PR:12167

  • ⧉ Fix loading of JSON in Vite. PR:12157

  • ⧉ Load dev mode gizmo for Vite when not in production. PR:12105

    Include gizmo in generated-flow-imports.js so it is also functional with v14 bootstrap mode.

• ⧉ All changes
