Two ways to provide configuration: command-line, yaml file.

• koanf

  13 2,655 7.3 Go

  Simple, extremely lightweight, extensible, configuration management library for Go. Support for JSON, TOML, YAML, env, command line, file, S3 etc. Alternative to viper.

  Of course. You should always use a good config package. caarlos0/env is okay but https://github.com/knadh/koanf is a better all around solution imo.
