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); } } ```
