# Unity Fleet MVP Technical Architecture

This document outlines the technical architecture for the Unity Fleet MVP components, defining the technology stack, data models, integration points, and deployment strategy.

## Overall Architecture

The Unity Fleet MVP suite will follow a modern web application architecture with these key characteristics:

- **Frontend**: React-based single-page applications (SPAs) for all user interfaces
- **Backend**: Simulated API endpoints with mock data (no actual backend server required for MVP)
- **Data Storage**: Local browser storage (localStorage/IndexedDB) for persistence during demonstrations
- **Deployment**: Static site hosting for all components
- **Integration**: Common data models and shared components across all MVPs

## Integration Strategy

### Shared Components

The following components will be shared across multiple MVPs:

- **Navigation Bar**: Consistent navigation across all applications
- **User Authentication**: Simulated login/logout functionality
- **Vehicle Cards**: Standardized vehicle display components
- **Charging Station Cards**: Unified station status display
- **Data Visualizations**: Common chart and graph components
- **Map Components**: Reusable mapping elements
- **Notification System**: Consistent alert and notification UI

### Data Sharing

Data will be shared between components using:

1. **Local Storage**: For persistent data across browser sessions
2. **URL Parameters**: For deep linking between applications
3. **Shared State Library**: Common Redux store for demonstration purposes

## Deployment Architecture

The MVPs will be deployed as static web applications:

```
┌─────────────────────────────────────────────────────────────┐
│                    Static Web Hosting                       │

│  Mobile     │ Charging  │  Energy   │Subscription│Interactive│
│   App       │   Hub     │Management │   Portal  │Deployment │
│ Prototype   │ Dashboard │Simulation │           │   Map     │
└─────────────┴───────────┴───────────┴───────────┴───────────┘
        │           │           │           │           │
        ▼           ▼           ▼           ▼           ▼
┌─────────────────────────────────────────────────────────────┐
│                    Landing Page Portal                      │
└─────────────────────────────────────────────────────────────┘
```

- Each MVP will be deployed as a standalone application
- A central landing page will provide navigation to all components
- All applications will be responsive and work on desktop and mobile devices
- No backend server is required as all data will be simulated

## Development Workflow

1. **Setup**: Create project scaffolding with shared components and styles
2. **Component Development**: Build individual MVPs in parallel
3. **Integration**: Connect components through shared data models
4. **Testing**: Verify functionality and user experience
5. **Deployment**: Deploy to static hosting
6. **Documentation**: Create user guides and demonstration scripts

## Technical Considerations

### Performance Optimization

- Use code splitting to reduce initial load times
- Optimize images and assets for web delivery
- Implement lazy loading for non-critical components
- Use efficient data structures for simulations

### Browser Compatibility

- Target modern browsers (Chrome, Firefox, Safari, Edge)
- Use progressive enhancement for advanced features
- Test on multiple devices and screen sizes
- Ensure accessibility compliance

### Simulation Fidelity

- Balance realism with performance
- Use realistic but simplified models for energy and financial simulations
- Ensure data consistency across all components
- Provide controls to adjust simulation parameters

This technical architecture provides the foundation for developing the Unity Fleet MVP components, ensuring a cohesive and impressive demonstration of the key concepts while maintaining technical feasibility within the project constraints.
