Tech talk: Micronaut

Transcript

1. Tech talk: Micronaut

2. How do we usually write Java applications? • Spring, Jackson,

   Hibernate, … • Utilizes annotations • Annotation-driven development

3. How do these annotations (usually) work? • Uses reflection API

   • Runtime evaluation takes time • Higher memory consumption • Less benefit from Ahead of Time compilation

4. Is there an alternative?

5. Meet Micronaut • Modern Java framework • Focuses on microservices

   and serverless • Annotation processors • Runs at compile-time

6. Advantages of Micronaut • No reflection • No classpath scanning

   • Decreased startup time & memory footprint • Works with annotations of other libraries!

7. Let’s try it out!

8. Remember this • Startup times not always important • Framework

   still young • Quality of documentation • Compilation takes longer

9. Source code

10. Thanks for listening!
