Starting with Quarkus
What you'll learn
- Understand the Quarkus ecosystem, where it comes from, its performance benefits
- Bootstrap a REST application with Quarkus
- Test it with JUnit and RestAssured
- Use injection with CDI
- Configure the application and Quarkus itself
- Use the dev/test/prod Quarkus profiles
- Package a Quarkus application in several JAR formats
- Generate a native binary thanks to GraalVM
- Build and execute a Docker container out of the application
- A recent Windows / Mac / Linux machine
- Knowledge of the Java language and the Java ecosystem (Maven, JUnit, GraalVM)
- Basic knowledge of RESTful Web Services
- Basic knowledge of Docker
This course is for Java developers who want to discover Quarkus. It’s a mixture of slides and code so you can “Understand and Practice” at the same time. This way, you learn the theory, and then put it into practice by developing an application step by step.
In this course you will go through an entire development cycle. After introducing Quarkus, you will make sure your development environment is set up, and you will go from bootstrapping a Quarkus application, to running it as a Docker container. The different steps you’ll go through are:
Check your development environment,
Get your hands on Quarkus,
Expose a REST endpoint using JAX-RS,
Inject beans with CDI,
Test the REST endpoint with JUnit and RESTAssured,
Configure the application with MicroProfile Configuration
Add profiles to the configuration,
Build executable JARs
Build a native executable and a Linux executable with GraalVM,
Check the performances of a Quarkus application,
Containerize the application with Docker and execute it.
At the end of the course you’ll get a good understanding of Quarkus. You will be able to bootstrap, develop, package and execute a REST application, but most important, take Quarkus to your next project.
Good luck for the course, and please reach out if you need any help or if you have any request: I’m here to help!
Who this course is for:
- Java developers curious about Quarkus
- Back-end Java developers willing to move their application to the cloud
- Spring or Java EE developers who need to compare their toolkit with Quarkus
Antonio Goncalves is a senior developer living in Paris. He evolved in the Java EE landscape for a while and then moved on to Spring, Micronaut and Quarkus. From distributed systems to microservices and the cloud, today he helps his customers to develop the architecture that suits them the best.
Aside from freelancing, Antonio wrote a few books (Java EE and Quarkus), talks at international conferences (Devoxx, JavaOne, GeeCon…), writes technical papers and articles and co-presents on the Technical French pod cast Les Cast Codeurs. He has co-created the Paris JUG, Voxxed Microservices and Devoxx France. For all his work for the community he has been made Java Champion ten years ago.
