Use environment variables (`process.env.NODE_ENV`) to conditionally include more detailed error information in development environments (e.g., stack traces) while providing a more generic and user-friendly error message in production to avoid exposing sensitive information. You can also use logging libraries to log the full error details server-side in both environments.
