• Add trees and transactions to signals module

Fixes

• Ensure exported WebComponent adds absolute links to document.css
  Commit · Pull request · Issues 21120, 19620

  When using a development bundle, WebComponentBootstrapHandler adds a tag to the embedding document that references document.css for all used themes (application and parents). However, the URL is relative to the embedding document instead of being an absolute URL to the CSS resource. Additionally, the tag is added even if the theme does not provide a document.css file, potentially causing 404 errors at runtime. This change ensures that the link URL is calculated based on the request and that it only adds tags for existing CSS files.

• Set page height to 100% instead of 100vh
  Commit · Pull request

  The PR modifies the page height from 100vh to 100% to prevent the content area from extending underneath the navbar on mobile devices: - body, #outlet { + html, body, #outlet { - height: 100vh; + height: 100%; width: 100%; margin: 0; }

• Watch active project resources
  Commit · Pull request

• Use add if not replacing
  Commit · Pull request

  Use add method if not replacing an old value.

• Constant pool to jackson
  Commit · Pull request

  Use jackson in constant pool UidlWriter to handle response in jackson. Part of #20741

• Prevent duplicated messages in client queue
  Commit · Pull request · Issue

  Messages sent by the Flow client are queued until the server acknowledges their reception. However, if there's a network fault, the Flow client immediately attempts to resend the message, resulting in duplicates in the queue. This change ensures that the same message is not added to the queue multiple times.

• Fix equality check in NavigationAccessControl
  Commit · Pull request · Issue

• Compute client-side feature flag values at runtime
  Commit · Pull request · Issue

  Activating a feature flag in the project does not work when a default bundle is used because the values of the flags sent to the client are hard-coded at bundle build time. Additionally, if a feature flag is active during bundle creation, it remains active on the client side even if the project does not activate it in the vaadin-featureflags.properties file. This change ensures that feature flags in the frontend bundle are always disabled initially and are activated on page load based on the current project settings.

Vaadin Flow 24.7.0

Changes since 24.6.0

All changes

Breaking changes

• Change minimal supported Node.js from 18 to 20
  Commit · Pull request

  Node.js 20 is the active LTS version. Node.js 18 will be end of life soon and new libraries like React 19 only support Node.js 20+.

New features

• Fault-tolerant messaging for server-client communication
  Docs · Issue

  Vaadin implements "Fault-tolerance messaging" against message loose due to various network errors by using message buffers on both sides. Server (Flow server) maintains a message buffer for UIDL messages that it sends upon request from browser. Browser (Flow client) maintains a similar message buffer for RPC messages that it sends upon end-user actions. This gives additional safe-guard level in applications on top of standard TCP/IP protocol and helps to avoid UI re-syncs.

  Includes the following commits:

  • Resend payload of reoccurring client request
    Commit · Pull request

    If the client request contains the previous id and exactly the same message content respond with the same payload as previously.

  • Queue message payloads
    Commit · Pull request · Issue

    Add sent payloads to message queue and resend if no response to message inside MaxMessageSuspendTimeout format server clear queue for push messaging.

• Add support for native image build Quarkus-based applications
  Commit · Pull request

  Adds support for native image build in Quarkus-based application by registering classes for reflection and patching Atmosphere.
  Run mvn package -Pproduction -Dquarkus.native.enabled=true to build a native image, then execute the output file to start the application.

  Docs
  A common guide and recommendations how to start configuring reverse proxy in front of Vaadin application.

• React 19 support behind a feature flag
