Full-stack web apps, 100% Java

on YouTube ↗44m

" summary

Live code shows a full-stack app built entirely in Java using Vaadin Flow and Spring Boot, no JS/HTML/CSS, with JPA persistence and a generated dataset of 100 contacts. Features: sortable Grid, Binder-backed CRUD with Bean Validation, debuggable server-side UI via JVM breakpoints, and an AI chat using Spring AI + OpenAI that streams tokens over websockets with Vaadin push. Presenter reports users see ~45% faster development and 98% say they ship faster, and the demo works end-to-end.
