## Development

### Prerequisites

- Node.js 18+ 
- TypeScript 5.6+
- Matter.js compatible system
- BLE support (optional, for BLE commissioning)

### Build

```bash
npm run build                # Build the project (compiles TypeScript)
npm run start                # Start with stdio transport (default)
npm run start:sse            # Start with SSE transport
npm run start:streamableHttp # Start with streamable HTTP transport
```

### Code Style

- Use ES modules with `.js` extension in import paths
- Strictly type all functions and variables with TypeScript
- Follow zod schema patterns for tool input validation
- Prefer async/await over callbacks and Promise chains
- Use descriptive variable names and proper error handling

## Contributing

We welcome contributions! Please follow these steps:

1. Fork the repository
2. Create a feature branch (`git checkout -b feature/amazing-feature`)
3. Commit your changes (`git commit -m 'Add some amazing feature'`)
4. Push to the branch (`git push origin feature/amazing-feature`)
5. Open a Pull Request

### Development Guidelines

- Follow the existing code style and patterns
- Add appropriate error handling and logging
- Update documentation for new features
- Test your changes thoroughly
- Follow semantic versioning for releases

## Troubleshooting

### Common Issues

1. **Device not found**: Ensure the device is in pairing mode and on the same network
2. **Connection timeout**: Check network connectivity and device availability  
3. **Permission errors**: Ensure proper permissions for BLE access (if using BLE commissioning)
4. **Port conflicts**: Change the PORT environment variable if using HTTP/SSE transport
5. **Controller initialization failed**: Check Matter.js dependencies and system compatibility
6. **Device commissioning failed**: Verify pairing code/PIN and network connectivity

### Debug Mode

Enable debug logging for troubleshooting:

```bash
export MATTER_LOG_LEVEL="debug"
```
