Best Practices

Never commit .env

Add .env to .gitignore before you create it. Commit .env.example with placeholder values so teammates know what variables are needed.

Use different values per env

Never share database credentials or API keys between development, staging, and production. Use separate keys — most providers (Stripe, OpenAI, AWS) support test vs live modes.

Validate at startup

Use zod (Node/TS) or phpdotenv's required() to validate env vars on boot. Fail fast with a clear error rather than discovering a missing key deep in a code path.
