Getting Started with the Micronaut® Framework

I did a similar presentation at JDevSummit 2024, GeeCON 2022, JCON-ONLINE 2022, Bucharest JUG, Merida JUG (Spanish talk), and Brighton Kotlin User Group.

In this session, Sergio del Amo introduces the Micronaut® framework and demonstrates how the Framework's unique compile-time approach enables the development of ultra-lightweight Java applications.

Compelling aspects of the Micronaut framework include:

  • Develop applications with Java, Kotlin, or Apache Groovy
  • Sub-second startup time
  • Small processes that can run in as little as 10 MB of JVM heap
  • No runtime reflection
  • Dependency injection and AOP
  • Reflection-free serialization
  • A database access toolkit that uses ahead-of-time (AoT) compilation to pre-compute queries for repository interfaces.
  • Cloud-native features

Sergio also demonstrates how you can generate GraalVM native images of your Micronaut applications to achieve instant startup and ultra-low memory footprint.

Sergio del Amo is a Micronaut core committer, Developer Advocate for the Micronaut Foundation, and host of the Micronaut podcast.

Elevator Pitch

This talk demonstrates how easy it is to get started with the Micronaut Framework through live-coding examples. Attendees will discover the most exciting features of the Framework and leave with the fundamentals necessary to begin building Micronaut applications.

Talk Outline

I deliver the talk with some slides introducing the framework, followed by a demo where I create a Micronaut Application and talk about some of the framework features; I leave some time at the end for Q&A.
