aconfig

Simple, useful and opinionated config loader.

Rationale

There are many solutions regarding configuration loading in Go. I was looking for a simple loader that is as easy to use and understand as possible. The goal was to load config from 4 places: defaults (in the code), files, environment variables, command-line flags. This library works with all of these sources.

Features

• Simple API.
• Clean and tested code.
• Automatic fields mapping.
• Supports different sources:
  • defaults in the code
  • files (JSON, YAML, TOML, DotENV, HCL)
  • environment variables
  • command-line flags
• Dependency-free (file parsers are optional).
• Ability to walk over configuration fields.
