Introduction to 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!
