pydantic-multi-source-settings

What problem does it solve?

This Skill helps applications acquire configuration from multiple sources with a clear precedence order: environment variables, .env files, and a remote configuration service, ensuring consistent, cached settings across the app.

Core Features & Use Cases

• Multi-source precedence: Environment variables override remote defaults, with .env as a fallback.
• Singleton settings: Provides a cached, single instance of the Settings model for the app lifecycle.
• Remote integration: Supports remote config services (e.g., Apollo, Consul) via a model_validator hook to fetch missing values at startup.

Quick Start

Define a Settings class using BaseSettings, configure env_prefix and env_file, implement a loader to fetch missing values from the remote service, and call get_settings() to obtain the singleton.
