Business point of view

This is an HR app. It features:

• HR task list
• Vacancy registry
• Resume registry
• Hiring history

In the app we have several processes:

• Submit a vacancy
• Submit a resume
• Vacancy - resume matching and interview planning
• Interview and hiring decision
• Candidate notification

Architecture

• Kogito app
• Data index
• Job service
• Mongodb as store
• Kafka as event bus
• Task list
• Console
• UI for registries based on graphql
• Mail or sms client (sw + Camel?)

No auth and no keycloack on purpose.

Init project

quarkus create app ru.sbertech.bpm.examples:kogito-demo-quickstart:1.0 \
  --extension='kogito, quarkus-resteasy-reactive, quarkus-resteasy-reactive-jackson' \
  --no-code

# be careful with reactive - not all extensions still support reactive, you may face conflict with ordinary resteasy

Add additional dependencies, see https://docs.jboss.org/kogito/release/latest/html_single/#ref-kogito-add-ons_kogito-creating-running. List of current extensions and addons:

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.

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

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

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

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.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/kogito-demo-quickstart-1.0-runner

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