OpenAPI and How It Can Be Applied to Kafka

API-First is one of popular approaches to building products. Exist many tools for supporting this approach. It is difficult to find some software that will help implement this approach for server applications that use message brokers as an integration tool, such as Apache Kafka, RabbitMQ, Apache ActiveMQ. We decided to fix it.

What you need to apply the API-First approach:

1. The API specification in the given format.
2. Code generation (models and signatures) according to the specification.
3. An easy way to migrate to using the API-First approach.

We will talk about the solution we have developed that provides all of theese three components for applications that use message brokers for integration.
