FAMILIAR PIECES. A FRESH CONNECTION.
Everything you know.
A new way to put it together.
Keep the tools you love. Bring your UI closer

Templates you already know.
Angular’s real template compiler. Familiar bindings, control flow, pipes, and scoped styles, with Java behind them.

The interface stays alive.
A page renders as HTML. A browser event becomes a Java method call. Jaspring sends back the changed views over WebSocket, with HTTP as a fallback.
