You already have Java endpoints, input validation, and HTML templates. Now you want inline editing and live search without maintaining a separate application in the browser.

HTMX lets an HTML element send an HTTP request and replace a selected part of the page with the returned HTML. Quarkus handles the routes and persistence; Qute renders the page and fragments. Web Bundler brings the frontend dependency into the Maven build.

We will build a small task manager with create, edit, delete, search, and validation. It uses a few inline JavaScript event handlers for error feedback, while keeping application state and rendering on the server. You do not need a separate Node.js build for this example.

Start with the project

The source project pins Java 21, Quarkus 3.30.4, Web Bundler 2.0.4, and HTMX 2.0.8. Start there for the versioned baseline.…
