Simple Chat-App using ReactJS, STOMP, Java SprintBoot with H2-Database containerized in Docker.
- Docker
docker-compose -f docker-compose.prod.yml buildto build the containersdocker-compose -f docker-compose.prod.yml up -dto run the containers- (https://localhost:3000) to access the application
docker-compose [-f docker-compose.prod.yml] build to build the containers [in production mode]
docker-compose [-f docker-compose.prod.yml] up [-d] to start up the [production] containers [in detached mode]
docker-compose down to tier down the containers
Further commands can be found on the official Docker documentation website
"docker-compose.yml" containing Docker config for development mode "docker-compose.prod.yml" containing Docker config for production mode
- Analyze Web-Security of the application in detail and take necessary actions
- Show connection errors in UI
- Simplify & optimize Docker configuration, eg. adding a .dockerignore file
| Dependency | Reason | Identified Risks |
|---|---|---|
| Java | Backend Technology as preferred in challenge description | |
| SpringBoot | Efficiently create Controller, Services and Repository | Lots of hidden magic |
| SpringSecurity | Handle general security incl. CORS | |
| H2-Database | Most simple in memory database | |
| Mockito | Simplifying mocking of test classes | Inappropriate usage can facilitate violation of SOLID |
| JUnit5 | To test the application |
| Dependency | Reason | Identified Risks |
|---|---|---|
| React | Efficiently develop Frontend application | Lacking support for very old browser versions |
| Material-UI | Efficient creation of a good-looking, responsive design | Big UI-framework (decreasing app performance) |
| Cross-Fetch | To communicate with Backend using REST | |
| STOMP.js | To communicate with Backend using STOMP | |
| SockJS | To communicate with Backend using STOMP | |
| Moment | Transforming dates - Do not reinvent the wheel | Rather large library, given that there is only one use case so far |
| Jest | To test the application |
