Environment Variables

Configure for different environments

Store configuration in environment variables, not code:

// .env file
API_KEY=secret123
DATABASE_URL=postgres://...

// In code
const apiKey = process.env.API_KEY;

Use dotenv package to load .env files in development. Never commit .env files.
