[H2] Quarkus Benefits

[H3] Developer Joy
A cohesive platform for optimized developer joy with unified configuration and no hassle native executable generation. Zero config, live reload in the blink of an eye and streamlined code for the 80% common usages, flexible for the remainder 20%.

[H3] Performance
Quarkus streamlines framework optimizations in the build phase to reduce runtime dependencies and improve efficiency. By precomputing metadata and optimizing class loading, it ensures fast startup times for JVM and native binary deployments, cutting down on memory usage.

[H3] Kube-Native
The combination of Quarkus and Kubernetes provides an ideal environment for creating scalable, fast, and lightweight applications. Quarkus significantly increases developer productivity with tooling, pre-built integrations, application services, and more.

[H3] Community and Standards
Quarkus provides a cohesive, fun to use, full-stack framework by leveraging a growing list of over fifty best-of-breed libraries that you love and use. All wired on a standard backbone.

[H3] Reactive Core
Built on a robust reactive core, Quarkus ensures fast and efficient performance, supporting the development of a wide variety of modern applications.

[H3] Container First
Quarkus tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.

The live coding fast feedback loop was very useful when developing with Quarkus. Although fast startup was nice, it wasn’t critical since our apps are long-running, but during development, as we tweaked our APIs, being able to immediately re-test saved us a ton of development time.

[H1] Get Started

[H3] It’s a snap to be up and running with Quarkus.

[H2] Step 1

[H3] Install via Command Line Interface
Open your favorite terminal and use JBang to install the Quarkus CLI. You do not need to have Java installed first.
[H4] For Linux, macOS, and Windows (using WSL or bash compatible shell like Cygwin or MinGW)

curl -Ls https://sh.jbang.dev | bash -s - trust add https://repo1.maven.org/maven2/io/quarkus/quarkus-cli/
curl -Ls https://sh.jbang.dev | bash -s - app install --fresh --force quarkus@quarkusio

[H4] For Windows using Powershell

iex "& { $(iwr https://ps.jbang.dev) } trust add https://repo1.maven.org/maven2/io/quarkus/quarkus-cli/"
iex "& { $(iwr https://ps.jbang.dev) } app install --fresh --force quarkus@quarkusio"

If it's your first time to install, you'll need to restart your shell.
[H4] Or, you can also install the CLI with SDKMAN!

sdk install quarkus

[H4] For more options, such as Homebrew or Chocolatey, see the Quarkus CLI guide.

[H2] Step 2

[H3] Create the Getting Started Application
Run this script in your CLI:

quarkus create && cd code-with-quarkus

[H2] Step 3

[H3] Run the Getting Started Application

quarkus dev

[H4] Boom! Your Quarkus app is now running at localhost:8080

[H2] Step 4

[H3] Live Coding with Quarkus
Quarkus makes it easy to change your code on the fly. Let's modify the RESTful endpoint
Open src/main/java/org/acme/GreetingResource.java in a text editor or your favorite IDE and change "Hello from RESTEasy Reactive" to "Hola from RESTEasy Reactive". Then refresh the browser and see the changes.

@Path("/hello")
public class GreetingResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String hello() {
return "Hello RESTEasy";
}
}
