npm: 8.0.0 or higher
OpenCage API Key: (Optional for development, required for production)

1. Environment Setup

Backend Configuration:

# Copy environment template
cp .env.example .env

# Edit .env file with your settings:
GEOCODING_API_KEY=your_opencage_api_key_here  # Get free key at https://opencagedata.com/
