Summary

Managing different configuration (database URLs, API keys, feature flags) across local, staging and production environments without hardcoding any of it.

How to Learn This

  • 1Set up separate `.env` files (or equivalents) for local, staging and production.
  • 2Learn to never commit real production secrets to any config file in git.
  • 3Practice validating required environment variables at app startup, failing fast if any are missing.
