Introduction to AsyncAPI for Apache Kafka
summary
AsyncAPI v2.0 describes Kafka brokers, topics and message payloads so a single YAML can generate docs and runnable clients. The demo uses @asyncapi/generator to produce HTML docs and a Node.js consumer, connects those artifacts to a cloud Kafka instance from ivan, and successfully receives echoed door‑sensor events. Tooling workflow includes the AsyncAPI Playground, VS Code support and microx for streaming test messages; schemas are reusable (Avro can be referenced) and one spec per service is recommended.
