System Architecture

A clean, layered architecture designed for maintainability and scalability.

1

Frontend (SPA)

  • Auth state management
  • REST API communication
  • Component-based UI
  • Real-time updates
2

Backend API

  • Authentication & Authorization
  • Role-based access control
  • Booking domain logic
  • REST endpoints
  • Validation & error handling
3

Database

  • Users table
  • Bookings table
  • Services table
  • Resources table

Stateless Authentication Flow

1

User submits credentials

2

Server validates and issues JWT

3

Client stores token securely

4

Token included in API requests

The authentication system is fully stateless, meaning the server does not store session data. Each request is independently verified using the JWT signature, enabling horizontal scaling without session synchronization concerns.
