Quarkus Reactive Test

This is a reactive REST API project built with Quarkus, the Supersonic Subatomic Java framework.
It demonstrates how to use Hibernate Reactive with Panache, PostgreSQL, and Testcontainers for modern, non-blocking backend development.

⚙️ Features

• Reactive REST endpoints using quarkus-rest
• Non-blocking PostgreSQL access with quarkus-hibernate-reactive-panache
• Hot reload and live coding in dev mode
• Testcontainers integration
• Gradle build system
• True end-to-end streaming API endpoint (/stream) delivering newline-delimited JSON (NDJSON), allowing fast and easy processing of large amounts of data as it arrives

🚀 Running the Application in Dev Mode

1. Start the PostgreSQL container

docker run --name pg-quarkus \
  -e POSTGRES_DB=demo \
  -e POSTGRES_USER=demo \
  -e POSTGRES_PASSWORD=demo \
  -p 5432:5432 \
  -d postgres:15-alpine

Make sure Docker Desktop is running.

2. Launch the application

You can run your application in dev mode that enables live coding using:

./gradlew quarkusDev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/mika-quarkus-test/q/dev/.

Database initialization
When the application starts, it will automatically create the necessary tables in your PostgreSQL database:
