Building modern desktop applications with Java doesn't have to mean using outdated UI toolkits like Swing or JavaFX. This guide demonstrates how to create a cross-platform Java desktop app using web technologies including shadcn/ui, React, and TypeScript. The approach uses JxBrowser to embed a Chromium-based web view, serves web resources from the classpath for security, and implements type-safe communication between JavaScript and Java using Protobuf and gRPC. This hybrid approach combines the power of Java backend with modern web UI capabilities.
