Best Practices

1. Sensitive Information: Use environment variables for sensitive information like API keys, passwords, and tokens.

2. Default Values: Provide sensible default values for non-critical environment variables.

3. Documentation: Document all environment variables used by your application, including their purpose and default values.

4. Validation: Validate environment variables after retrieving them to ensure they meet your requirements.

5. Configuration Structure: Use a structured approach to loading environment variables into a configuration object.

6. Error Handling: Implement proper error handling for missing critical environment variables.
