Features

Core Capabilities

🔐

JWT Authentication

Stateless authentication using signed JWT access tokens (short-lived) and refresh tokens (long-lived) for seamless session continuation.

🛡️

Role-Based Access Control

RBAC middleware enforces role permissions at both the Django API level and React route level — users only access what their role permits.

⚛️

React Protected Routes

Frontend route guards check token validity before rendering protected components, redirecting unauthenticated users to login automatically.

🔄

Silent Token Refresh

Axios interceptors automatically retry failed requests with a refreshed access token — keeping sessions alive without user interruption.

⚡

CI/CD with GitHub Actions

Automated workflow pipeline for testing, building, and deploying both frontend and backend components on every push to main.

🔗

REST API Integration

Clean RESTful API: POST /api/login/, POST /api/logout/, GET /api/user/ — designed for easy integration with any frontend.

Frequently Asked Questions

JWT is stateless — the server doesn't need to store session data in a database. Each token is self-contained with user identity and role information. This makes it ideal for decoupled React frontends calling Django APIs, enabling horizontal scaling without shared session storage.

Refresh tokens are stored in HttpOnly cookies — inaccessible to JavaScript — preventing XSS attacks from stealing them. Access tokens are kept in memory (React state), not localStorage, to further reduce exposure to XSS. This follows OWASP security recommendations for SPAs.

GitHub Actions triggers on push to main. The workflow runs Django unit tests, builds the React frontend, checks for dependency vulnerabilities, and deploys both services. This ensures every commit is validated before reaching production — with zero-downtime deployment steps.

Yes. The architecture is designed as a scalable foundation. For production, swap SQLite with PostgreSQL, add Redis for token blacklisting on logout, configure HTTPS, set production CORS origins, and integrate a proper secret management system. The modular structure makes each upgrade straightforward.

RBAC (Role-Based Access Control) assigns each user a role (e.g., Admin, User). The Django API checks the role claim from the JWT payload on protected endpoints and returns 403 Forbidden if the role doesn't have permission. On the React side, route components check the stored role before rendering, preventing unauthorized page access.
