Vaadin: Modern Web UIs in Pure Java—A Live-Coding Tour

JavaScript pasta, web toolchains, endless build steps and an ever-shifting front-end landscape slows down even qualified Java teams. Vaadin shows there is another way: an intuitive Java API, type-safe client-server communication and +50 accessible web components deliver a productive UI—without a single line of JavaScript, CSS or HTML. It enables full-stack Java web application development and, when needed, integrates seamlessly with modern front-end technologies like React.
In this talk we will

• position Vaadin in today’s web stack,
• sketch the architecture, state-handling and browser-server-communication,
• demonstrate how the open-source framework fits cleanly into Web- and Java development,
• and build a full-stack application live: data binding, routing, theming and deployment — in under 23 minutes.

Key Takeaways

1. Create a Vaadin project in seconds and start coding right away.
2. Java-only full-stack cuts the communication- and integration-friction between front- and back-end.
3. Open Source & Extensibility: full access to well-documented source code lets you adapt or extend components to match any domain demand.

Target Audience
Java developers and architects who need web UIs but have no time for the “framework jungle”; teams migrating from JSF, Swing, Oracle Forms, Thymeleaf or pure JS stacks; anyone seeking maximum full-stack productivity on the JVM.
