poc_spring_graphql

Description:

This was a small project impleted in JAVA 17 to understand how does Spring for GraphQL works.
To handle the data I used PostgresQL.

How to run it:

In order to run this project you will need Docker and Java 17 - or higher.

In order to run this project the simpler way would be to make the following:

make run

This way you will start a container running the database and the app. Everything will start automatically.

To stop it, you can simply do the following:

make stop

How to test it:

Once your application has started you can go tolocalhost:8080/graphiql and try the following queries:

   query {
