Package io.quarkus.qute.runtime.debug

Class DebugQuteEngineObserver

java.lang.Object

io.quarkus.qute.runtime.debug.DebugQuteEngineObserver

@Singleton
@Experimental("This observer is experimental and may change in the future")
public class DebugQuteEngineObserver
extends Object

Observes the creation of Qute engines and attaches the Qute debugger in development mode.

When a new EngineBuilder is observed and the application is started with "-DquteDebugPort" and running in development mode with quarkus.qute.debug.enabled=true, this observer:

• Enables template tracing on the engine (required for the debugger).
• Registers a RegisterDebugServerAdapter to allow DAP clients to connect.

The cleanup() method ensures that the debugger is properly reset when the application shuts down.
