quarkus-reactive-hibernate-graphql-crud

This project demonstrates a graphql crud application together using smallrye-graphql, panache and hibernate reactive(with ORM). It presents a set of movies together with actors and can be queried and mutated accordingly.

This project uses Quarkus, the Supersonic Subatomic Java Framework.

This project is presented in the following article.

Creating a CRUD app with Quarkus, Reactive Hibernate, Panache and GraphQL using a PostgreSQL database

Run Postgres docker container

 docker run -d --rm --name my_reative_db -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password -e POSTGRES_DB=my_db -p 5432:5432 postgres:10.5

Clean DB

docker rm $(docker ps -a -q) -f

docker volume prune

Run live coding

./mvnw compile quarkus:dev

Native image build

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

Go to the GraphQL UI

http://localhost:8080/q/graphql-ui/
