Veaktor - Vaadin Add-on Directory
Use Project Reactor and Vaadin together
Veactor is a set of helpers to use Project Reactor and Vaadin together.
The main functionality is focused on updating parts of a Vaadin UI when new elements are published to a `Flux` or `Mono`.
This is done using an appropriate `subscribe` method in the `Veactor` class.
Each of those methods requires a component instance that is used to control the life cycle of the subscription - the subscription is started when the component is attached (happens immediately if it's already attached when `subscribe` is called) and the subscription is closed when the component is detached again.
```java
@Push
@Route("hello")
public class HelloWorldView extends VerticalLayout {
public HelloWorldView() {
Flux flux = Flux.interval(Duration.ofSeconds(1)).take(10);
Span message = new Span("Waiting for updates...");
Veactor.subscribe(this, flux, value -> message.setText("Received value " + value));
add(message);
}
}
```
