Quarkus Kotlin OpenAPI

Quarkus Kotlin OpenAPI is a code generator that generates server and client Kotlin code from an OpenAPI specification. The generated code is intended to run with Quarkus, the framework for writing JVM-based applications.

This documentation is still in development and does not cover every feature of the code generator yet.

Features

• Generate type-safe, high-performance, fully reactive server and client code in Kotlin from an OpenAPI specification with a focus on correctness and developer experience.
• Generate test clients for easy testing of your API implementation.
• Built-in support for patching third party OpenAPI specifications to your needs.
• Partial generation allows you to generate only the parts of the API you need for your application.
• Customizable validation, type mapping and error handling.
• Generated code does not rely on reflection which improves performance and allows the use of native image compilation with GraalVM without any additional configuration.
