Servease Full-Stack Role-Based Application

This repository now contains:

• servease-backend: Java Spring Boot REST API with session auth + role checks.
• servease-frontend: Angular app with login/logout, guards, role dashboards, profile, and admin user management.

Roles Supported

• ADMIN
• CUSTOMER
• SUPERVISOR
• TECHNICIAN

Backend highlights

• Auth endpoints:
  • POST /auth/login?userId=&password=
  • POST /auth/logout
  • GET /auth/session/validate
• User registration + management via /user
• Admin-only user listing/update/delete in UserController
• In-memory session handling using sessionId header
• PostgreSQL via environment-configurable datasource properties

Frontend highlights

• Angular route protection with:
  • Auth guard (must be logged in)
  • Role guard (must match route role)
• Separate pages:
  • /admin
  • /customer
  • /supervisor
  • /technician
  • /profile
  • /admin/users
• Session storage + interceptor for attaching sessionId
• Basic API error interceptor handling unauthorized sessions

Local setup

1) PostgreSQL

createdb servease_db

Or configure your own DB and export:

export DB_URL=jdbc:postgresql://localhost:5432/your_db
export DB_USERNAME=your_user
export DB_PASSWORD=your_password

2) Run backend

cd servease-backend
mvn clean install
mvn spring-boot:run

Backend runs at http://localhost:8080 by default.

3) Run frontend

cd servease-frontend
npm install
npm start

Frontend runs at http://localhost:4200 and talks to http://localhost:8080.

Notes

• sessionId is sent as an HTTP header for protected requests.
• Admin user management page calls backend /user API and is role-protected in frontend and backend.
