The application starts with a secure user registration system that implements multiple layers of protection.
Clean registration interface with real-time validation and security features including input sanitization and XSS protection.
After authentication, users land on the main dashboard which serves as the central hub for all game activities.
The home dashboard integrates multiple features in a single view: game area for quick matches, friend list management, real-time chat system, and online players list. The component-based architecture allows for seamless updates without page refreshes.
Before each match, players enter a lobby system that handles matchmaking and game setup.
The game lobby shows opponent information and allows players to prepare for matches. WebSocket connections ensure real-time updates on player status and readiness.
The core gaming experience leverages Babylon.js for smooth 3D graphics and WebSocket for real-time synchronization.
The main attraction - smooth 3D Pong gameplay powered by Babylon.js rendering engine. Real-time multiplayer synchronization ensures fair gameplay with minimal latency. The physics engine handles ball movement, paddle collisions, and scoring.
Each player has a comprehensive profile system that tracks statistics and social connections.
Detailed user profiles display game statistics, win/loss ratios, match history, and social connections. The friend system allows users to build gaming networks and challenge specific opponents.
Users can customize their profiles and manage security settings through a comprehensive settings panel.
The profile settings page provides complete account management including avatar upload, two-factor authentication setup, password changes, and privacy controls. All file uploads are validated and sanitized for security.
The tournament system manages 4-player competitions with automatic bracket generation and progression tracking.
Tournament semifinal stage showing the bracket progression. The system automatically manages player advancement and schedules upcoming matches based on results.
The climactic tournament final where the remaining two players compete for the championship. The system maintains all tournament history and statistics.
Tournament victory screen celebrating the champion with final standings, achievements, and statistical summary. Winners are recorded in the global leaderboards.
The application includes comprehensive monitoring using Prometheus for metrics collection and Grafana for visualization.
Production-ready monitoring dashboard built with Grafana shows real-time system metrics, game statistics, user activity, and performance data. Custom metrics track game-specific events like match completions, user registrations, and system load.
The monitoring setup includes:
- System Metrics: CPU, memory, disk usage via Node Exporter
- Application Metrics: Custom game events, user actions, WebSocket connections
- Performance Tracking: Response times, database queries, error rates
- Business Metrics: Active users, games played, tournament completions
- TypeScript: Type-safe development with modern ES6+ features
- Vanilla TS: No framework dependencies, custom component system for maximum control
- Babylon.js: 3D graphics engine providing smooth gameplay rendering
- Tailwind CSS: Utility-first styling for responsive design
- WebSocket API: Real-time bidirectional communication
- Component Architecture: Custom router and state management
- Node.js + Fastify: High-performance web server with plugin ecosystem
- SQLite: Embedded database for development, easily scalable to PostgreSQL
- WebSocket Server: Real-time game state synchronization
- JWT + Argon2: Secure authentication with password hashing
- Speakeasy + QRCode: Two-factor authentication implementation
- OAuth2: Google authentication integration
- XSS Protection: Input sanitization and output encoding throughout
- CSRF Protection: Token-based request validation
- Rate Limiting: API endpoint protection against abuse
- JWT Rotation: Automatic token refresh for session security
- Mandatory 2FA: Enhanced account protection
- Input Validation: Server-side validation for all user inputs
- Docker Containerization: Multi-service architecture with isolated containers
- Docker Compose: Service orchestration and networking
- Nginx: Reverse proxy, SSL termination, and static file serving
- Prometheus: Metrics collection and alerting
- Grafana: Dashboard creation and data visualization
- SSL Certificates: Automated certificate management
