With Idle, you can monitor whether a user is active or inactive in your application.
This is achieved by tracking keyboard and mouse events within the window. You can set a specified inactivity time, after which the userinactive style is applied to the BODY element. Additionally, an optional event can be sent to the server-side component.
Try the add-on demo at idle-demo.fly.dev
In the demo you can see CSS color changes applied immediately and text changed on server-side listeners.
- Apply CSS changes based on user inactivity
- Server-side listener for idle/resume
- Add support for Java 8 lambdas and Vaadin 8
- Add support for Vaadin 24
