SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sage's configuration system provides a unified foundation to load, merge, and validate settings from multiple sources, including defaults, project and global configs, environment variables, and CLI arguments.

Core Features & Use Cases

  • Multi-source loading: deterministic merging across defaults, project/global config, environment, and CLI overrides.
  • Credential management: centralized resolution and injection of credentials into runtime configuration.
  • Validation & persistence: enforce rules, support runtime updates, and persist changes to config and credentials.

Quick Start

Example: Create a config pipeline with Default -> Global File -> Project File -> Env -> CLI Args, then call load() to obtain a validated Config.

FAQPage Schema
How do I merge configuration from multiple sources like environment variables and CLI overrides?▼

Multi-source configuration merging applies a deep-merge behavior across defaults, project/global files, environment variables, and CLI overrides to produce a unified runtime state.

What is the best way to manage credentials in a multi-environment configuration setup?▼

Credential management in a multi-environment setup uses centralized resolution and injection of credentials into the runtime configuration, supporting consistent operation across development, staging, and production.

How do I validate runtime configuration and persist changes across environments?▼

To validate runtime configuration and persist changes, you enforce validation rules during the loading phase and utilize runtime persistence modules to save configuration and credential updates.

Can I configure a deterministic config pipeline for development, staging, and production?▼

Yes, you can configure a deterministic pipeline by layering defaults, global files, project files, environment variables, and CLI arguments to support consistent operation across development, staging, and production.

Why does my deep-merged configuration not reflect CLI overrides correctly?▼

Deep-merged configuration may not reflect CLI overrides correctly if the deterministic loading pipeline is misconfigured, requiring verification of the ConfigLoader's source priority and validation rules.
