Prototype of an application for energy trading

The prototype uses current technologies against the background of realistic requirements from the field of energy trading and order management. The backend is based on Spring Boot and is divided into several microservices. Angular is used as the UI framework in the front end. The infrastructure of the development environment and the test system are based on Docker and Docker-Compose. Communication between the microservices is asynchronous via RabbitMQ with request-response and messaging. The backend provides web services for the frontend. Data is also sent from the backend to the frontend via Websocket / STOMP protocol to enable near-real-time updates. Angular signals are used in the frontend to hold the state in the services. To test the application, integration tests are implemented in addition to the regular unit tests to ensure the correct functioning of the application in interaction with the database, RabbitMQ and Kafka.
