This demo showcases the complete NovaLang Framework capabilities.

## Features Demonstrated

✅ **Web Framework** - Spring Boot-like annotations and REST APIs  
✅ **Native Execution** - No JVM required, runs directly  
✅ **Auto-Configuration** - Zero-config application setup  
✅ **Developer Experience** - Simple, clean syntax  

## Running the Demo

```bash
# Run the application
nova

# Or use the runtime directly  
python -m novalang_runtime
```

## API Endpoints

- `GET /` - Welcome page
- `GET /api/hello` - Hello API with JSON response
- `POST /api/data` - Data submission endpoint

## What This Shows

This demo proves that NovaLang Framework provides:

1. **Familiar Development** - Spring Boot-like experience
2. **Modern Syntax** - Clean, readable NovaLang code  
3. **Enterprise Features** - REST APIs, JSON responses
4. **Easy Deployment** - Single command execution
5. **Native Performance** - Fast startup, no JVM overhead

Visit http://localhost:8080 when running to see it in action!
