Vaadin Flow is the best Java framework I used in my career

Thank you!!! This explanation is awesome and also beautiful how vaadin works. My background is from dojo js and VUE js combined with Java in the server side. But the way vaadin works handle all that complexity and seems easy on the surface.

A video tutorial on how to make desktop apps with vaadin with integration probably with electron/tauri would be great ⚡⚡

Is it possible to introduce truly stateless model to Vaadin Flow in some future releases?
