This sample shows how to build a Javalin microservice and compiling it to native code with GraalVM. I don't expect it to work on anything else than Linux AMD64. Maybe OSX.

Try it out:

docker run -d --init -p 7000:7000 birdy/graal-javalin
curl localhost:7000

Build either by using Docker and running docker build . or directly with Gradle and native-image by running make build native.

Find the docker image of this example on DockerHub.
