What Is AsyncAPI?

AsyncAPI is an open-source specification for defining event-driven, asynchronous APIs. It's the event-driven equivalent of OpenAPI and describes message-based communication patterns.

AsyncAPI generation is used for:

  • Event-Driven Architectures: Documenting Kafka, RabbitMQ, and MQTT APIs.
  • Microservices: Defining async communication contracts.
  • API Documentation: Generating AsyncAPI specs from message samples.

  3. Review Output: Your result appears instantly in the output panel.
  4. Copy to Project: Use the Copy button to grab the result and paste it into your project.

Frequently Asked Questions

How are nested objects handled?

Nested objects generate their own named type definition, referenced from the parent type. This keeps your code organized and reusable.

How are arrays typed?

Arrays infer their element type from the first item. Arrays of objects generate a collection type of the corresponding object type.
