What is Javalin?
Javalin is a web framework designed for Java and Kotlin developers seeking simplicity and efficiency in building web applications. It operates on top of Jetty, a stable JVM web server, ensuring robust performance while maintaining a minimal codebase. The framework emphasizes ease of use by avoiding complex inheritance structures and rarely requiring interface implementations, making it accessible for developers of all skill levels.
With built-in support for OpenAPI, including Swagger UI and ReDoc, Javalin facilitates API documentation and testing. It offers flexibility by supporting both blocking and asynchronous programming models, allowing developers to choose based on their application needs. The framework's interoperability ensures that applications can be developed similarly in Java and Kotlin, promoting code reuse and reducing learning curves.
