configuration
A Go library for injecting configuration values into structs from environment variables, flags, JSON files, or default tags.
What is configuration?
Configuration is a Go library that injects values into struct fields from various sources like environment variables, command-line flags, JSON files, or default tags. It solves the problem of scattered configuration logic by centralizing it within a single struct model, making configuration management more declarative and maintainable.
Go developers building applications that require flexible, multi-source configuration management, particularly those following 12-factor app principles or working on CLI tools and services.
Developers choose Configuration for its simplicity, extensibility, and zero-dependency design. It offers a clean, tag-based approach to defining configuration metadata directly in structs, with customizable provider priorities and support for custom types.
