Database with Docker-compose

First we will need a PostgreSQL database; you can launch one easily if you have Docker-compose installed:

docker-compose up -d

Build and start the frontend

Pre-requisites : npm v6.9.0

cd hotel-quarkus

npm install

You can then start the frontend, this start a node server on port 8081 :

npm run serve

You can also build and package the frontend, then copy the generated files to the backend folder :

cd hotel-quarkus

npm install

npm run build

cp -R dist/* ../src/main/resources/META-INF/resources/

Running the application in dev mode

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

./mvnw compile quarkus:dev

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

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/quarkus-booking-demo-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.html.
