AI in Vaadin Applications

Leverage AI in your Vaadin applications with practical use cases and setup options that fit your project.

In this section, you’ll learn how to connect a Vaadin application to a Large Language Model (LLM) and integrate AI features into your workflows. Using common Vaadin application scenarios as examples, you’ll explore typical UI patterns for AI integration. The focus is on simple, adaptable examples that you can quickly implement in your own projects.

You’ll learn how to:

  • connect your application to an AI client with popular Java libraries such as Spring AI and LangChain4j,

  • choose Vaadin components that create intuitive, AI-powered workflows — such as MessageInput, MessageList, and Scroller, and

  • deliver real-time updates to users through server push.

Technical Setup
Configure API keys and IDE settings so your Vaadin application can connect to hosted or local LLMs.
Quick Start-Guide
A compact chat view with streaming, correct scrolling, and message context.
