Micronaut, introduced in early 2018 by Object Computing, is a full-stack JVM-based framework for creating microservices-based, cloud native, and serverless applications that can be written in Java, Groovy, or Kotlin. This new framework provides a simple compile-time, aspect-oriented programming API that does not use reflection. Micronaut supports GraalVM-native images and offers compile-time support for Swagger, validation, and mapping annotations. With its own nonblocking web server built on top of Netty, reactive clients can be built declaratively and are implemented at compile time. This session provides an overview of Micronaut, followed by a live demonstration of an application with microservices written in Java, Groovy, and Kotlin, respectively.
