Java desktop apps with web front end (Angular, react)
krema.buildI've built a similar framework called Java Electron (https://github.com/tanin47/java-electron).
Java as the backend, and JS as the frontend.
It actually uses WebView, not Chromium.
The most important feature is: Java Electron can be published on Apple App Store and Microsoft Store. This requires proper code-signing and etc.
Backdoor, a modern database tool, is a showcase for it: https://github.com/tanin47/backdoor
