Implementation of the MicroProfile Reactive Messaging specification

This project is an implementation of the (next to be) Eclipse MicroProfile Reactive Messaging specification - a CDI extension to build event-driven microservices and data streaming applications. It provides support for:

It also provides a way to inject streams into CDI beans, and so link your Reactive Messaging streams into CDI beans,or JAX-RS resources.

Getting started

Prerequisites

See PREREQUISITES.md for details.

The build process requires Apache Maven and Java 8+ and can be performed using:

mvn clean install

How to start

The best way to start is to look at the examples/quickstart project. It's a Maven project listing the minimal set of dependencies and containing a single class:

package io.smallrye.reactive.messaging.quickstart;

import org.eclipse.microprofile.reactive.messaging.Incoming;
import org.eclipse.microprofile.reactive.messaging.Outgoing;
import org.eclipse.microprofile.reactive.streams.operators.PublisherBuilder;
import org.eclipse.microprofile.reactive.streams.operators.ReactiveStreams;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.se.SeContainerInitializer;

@ApplicationScoped
public class QuickStart {

  public static void main(String[] args) {
    SeContainerInitializer.newInstance().initialize();
  }


  @Outgoing("source")
  public PublisherBuilder<String> source() {
    return ReactiveStreams.of("hello", "with", "SmallRye", "reactive", "message");
  }

  @Incoming("source")
  @Outgoing("processed-a")
  public String toUpperCase(String payload) {
    return payload.toUpperCase();
  }

  @Incoming("processed-a")
  @Outgoing("processed-b")
  public PublisherBuilder<String> filter(PublisherBuilder<String> input) {
    return input.filter(item -> item.length() > 4);
  }

  @Incoming("processed-b")
  public void sink(String word) {
    System.out.println(">> " + word);
  }

}

Run the project with: mvn compile exec:java -Dexec.mainClass=io.smallrye.reactive.messaging.quickstart.QuickStart:

>> HELLO
>> SMALLRYE
>> REACTIVE
>> MESSAGE
