Can I load configuration from sources other than environment variables?

Yes, the skill covers using ConfigProvider to load data from JSON objects, Maps, or custom external sources through composition.

How does this skill handle sensitive information?

It utilizes Effect's Redacted and Secret types to ensure sensitive values like API keys are never accidentally logged or leaked in plain text.

How do I handle default values for missing variables?

The skill explains the use of the Config.withDefault operator to provide safe fallback values when a specific configuration key is not found.

Can I nest configurations for better organization?

Yes, it provides implementation patterns for using Config.nested to group related settings under specific namespaces like DATABASE or SERVER.

Does it support validation for configuration values?

Absolutely. It demonstrates how to integrate Effect Schema to validate types, numeric ranges, and string patterns for your configuration values.
