Sandbox/Playground(ReactJs & Spring Boot & Spring Data JPA + H2 Database & REST Api Endpoints)

Frontend also fetches DB structure from Github just like the backend since it served as a React.js sandbox before backend even existed. Hence this is a disconnected mess and I was in the process of tidying it up and replicating backend functionality in the respective backend when a potentailly similar but expanded usecase came up, which is currently in private repo and will be done cleanly via Quarkus (probably even though I kinda like Springboot DI better semantically), RestEasy Reactive, Hibernate ORM Reactive, PostgreSQL Reactive and Websockets, together with a React.js frontend.
