Micronaut is a JVM framework for building services using Java, Kotlin or Groovy. It distinguishes itself through a small memory footprint and short startup time; it achieves these improvements by avoiding runtime reflection for dependency injection (DI) and proxy generation, a common shortcoming of traditional frameworks, and instead uses a DI/AOP container which performs dependency injection at compile time. This makes it attractive not just for standard server-side microservices but also in the context of, for example, the Internet of Things, Android applications and serverless functions. Micronaut uses Netty and has first-class support for reactive programming. It also includes features such as service discovery and circuit breaking that make it cloud-native friendly. Micronaut is a very promising entrant to the full-stack framework for the JVM space, and we're seeing it in more and more projects in production, prompting us to move it to Trial.
