PS StackOverflow

Stack Overflow–style Q&A app: React frontend, Spring Boot API, MySQL, and a notification microservice for ban email/SMS.

Architecture

[React + Vite]  →  [Main API :8080]  →  [MySQL]
                         │
                         │ HTTP POST /api/notifications/ban
                         ▼
              [Notification Service :8081]
                         │
                         ├── Email (console or SMTP)
                         └── SMS (console)

CI	GitHub Actions

Tests

cd notification-service && mvn test
cd backend && mvn test
cd frontend && npm ci && npm run test:ci && npm run lint

CI (GitHub Actions)

On every push and pull_request, CI Pipeline runs:

Job	Command
Notification Service Tests	mvn test in notification-service/
Java Unit Tests	mvn test in backend/
React Vitest Tests	npm run test:ci in frontend/
Frontend ESLint	npm run lint in frontend/

Team notes

• După git pull, rulați npm install în frontend dacă s-au schimbat dependențele.
• Start notification-service before testing ban flows from the main API.
