AsyncAPI + Spring Cloud Stream = Event-Driven Microservices Made Easy
summary
AsyncAPI documents feed the AsyncAPI generator to generate Spring Cloud Stream projects that use binders for RabbitMQ Kafka and Solace PubSub+; demos show Node.js with Mosquitto and Java Spring Cloud Stream with the java-spring-cloud-stream-template. A simulator publishes temperature readings, a collector emits operational alerts, and a processor aggregates 8 operational alerts over 10s to publish an average aggregate alert. Code generation creates runnable apps and broker topics automatically, messages route successfully; the map visualizer fails only due to a missing Google Maps key.
