PASS is a full-stack, production-oriented social networking platform engineered using scalable mobile architecture principles.
The system is built with a strong focus on:
- Secure authentication
- Modular state management
- Real-time communication
- Clean separation of concerns
- Deployment-ready structure
This repository represents the Architecture & Portfolio Edition of the platform.
Mobile Client (React Native + TypeScript) ↓ API Layer (Node.js / REST) ↓ MySQL Database ↓ JWT Authentication Layer ↓ Role-Based Access Control (RBAC) ↓ Session & Token Rotation Management
The system is designed to remain stateless on the server while maintaining secure session handling on the client.
- JWT Access Token + Refresh Token Rotation
- Hashed Refresh Token storage
- Token revocation mechanism
- Device-aware session management
- Middleware-based authorization enforcement
- Feature-driven folder organization
- API abstraction layer
- Service-based business logic separation
- Context-based global state handling
- Reusable UI component system
- WebSocket integration for:
- Live friend requests
- Real-time updates
- Presence handling
- Context-based structured global state
- Clean data flow separation
- Predictable state updates
