Notable Changes in Vaadin 25.1

1. UI State Management with Signals (Flow)

Vaadin 25.1 introduces Signals to handle UI state in Flow. This enables cleaner code with a single source of truth for each component property.

Versatile Signal Types

Signal instances hold UI state values and automatically track which components need updating when a signal value changes.

• Local signals: For a view’s or component’s internal state.
• Shared signals: For sharing state with other users in real time.
• Computed signals: For deriving values based on other signals.

Signal Bindings

New bindXyz methods are available for all components to automatically update properties based on signal changes. Examples include:

• Generic features: bindVisible
• Component-specific properties: bindMin in Date Picker
• Two-way bindings: bindValue for all input fields

2. New UI Components (Preview)

Slider & RangeSlider

New slider input components for selecting:

• A single value (Slider)
• Two values from a range (RangeSlider)

Badge

A new component for displaying statuses and notification indicators. Visual variants include:

• Icon-only, Number-only, and Dot
• Multiple color options

AI Integration

New Flow features for integrating AI-powered functionality into Vaadin apps:

• AIOrchestrator: Manages interactions between UI components and LLMs.
• LLM Providers: Out-of-the-box implementations for Spring AI and LangChain4j.

Upload Components

New standalone components for flexible file upload UIs:

• UploadButton
• UploadDropZone
• UploadFileList (includes a thumbnail-bar style variant)

3. Aura Theme Enhancements

The new Aura theme, introduced in V25, receives major updates in this beta, including previously missing component style variants and a refreshed default color palette.

4. Component Enhancements

Common Variant Entries

Component style variants that work in both Aura and Lumo themes now have common, unprefixed entries in the *Variant classes.

• Example: ButtonVariant.PRIMARY

Key Updates by Component

5. 🎨 Major Vaadin Copilot Redesign

Vaadin Copilot has been completely overhauled with a streamlined look and improved workflow.

New Toolbar & Working Modes

The traditional Vaadin button and drawers have been replaced with a modern toolbar featuring four operational modes:

• Play Mode: Copilot is idle and does not affect the running application.
• Inspect Mode: Read-only tools for inspecting application structure.
• Test Mode: Tools for accessibility checks and UI test generation.
• Edit Mode: Drag-and-drop UI modification, copy-paste, and AI-powered features.

Redesigned Panels & Settings

• Modern Aesthetic: Most internal panels now feature a consistent look for improved usability.
• Settings Panel: Copilot is now customizable via a new dedicated Settings interface.

Expanded Access

All premium features—including source code manipulation and AI—are now available to any user with an active Vaadin.com account. Users simply need to log in via the toolbar to unlock these capabilities.
