🔗 EnvGuard — env_guard v2.0.0

EnvGuard simplifies the task of managing environment variables in Elixir applications. By allowing developers to define required environment variables, their types, and whether they’re optional, EnvGuard improves the reliability of configurations. This library ensures that environment variables are both fetched and validated against Elixir types, reducing common runtime errors.

For instance, it provides functions like required/3 to fetch mandatory variables with constraints, and optional/4 for those that aren't strictly necessary. Without EnvGuard, errors related to missing or improperly formatted environment variables could lead to failed application startups. The article outlines installation tips, type support, and various constraints for validation, making it a must-read for Elixir developers aiming for cleaner and more robust configuration handling.
