What problem does it solve?

This Skill simplifies the complex task of managing configuration for Go applications, offering a flexible and robust solution for loading, merging, and accessing settings from various sources.

Core Features & Use Cases

• Multi-Source Configuration: Load settings from files (YAML, TOML, JSON, HCL, dotenv), environment variables, command-line flags, and remote stores (Vault, Consul, etcd, S3, AWS Parameter Store).
• Provider Chaining & Merging: Seamlessly merge configurations from multiple sources, with later sources overriding earlier ones.
• Type-Safe Access: Retrieve configuration values as specific Go types (string, int, bool, etc.) with helpful getter methods.
• Use Case: When developing a microservice, use this Skill to load default configurations from a file, override them with environment variables for production deployment, and finally allow command-line flags for runtime adjustments.

Quick Start

Use the koanf skill to load configuration from a file named 'config.yaml' and retrieve the 'server.port' setting.
