Environment Variables Handler
Master configuration management and environment variable handling across development, staging, and production environments.
When to Use
- Setting up development environments
- Managing secrets and API keys
- Configuring multi-environment deployments
- Docker and container configuration
- CI/CD pipeline environment setup
- Configuration validation
- Database connection management
Principles
- Never commit secrets - Use .env files (git-ignored)
- Separate by environment - dev, staging, production configs
- Validate on startup - Fail fast if required vars missing
