Go Conf Builder

Go Conf Builder is a lightweight configuration library inspired by Viper. It allows loading configuration values from various file formats and environment variables.

Features

• Read JSON, YAML, TOML, INI and XML files
• Set default values for keys
• Bind environment variables with optional prefixes
• Automatic environment variable loading
• Watch configuration files for changes and react via callbacks

Installation

go get github.com/mirkobrombin/go-conf-builder

Basic Usage

cfg := conf.New()
cfg.SetConfigName("config")
cfg.AddConfigPath(".")
cfg.SetEnvPrefix("MYAPP")
cfg.AutomaticEnv()
cfg.SetDefault("port", 8080)

if err := cfg.ReadInConfig(); err != nil {
    fmt.Println("error loading config:", err)
}

fmt.Println("port:", cfg.GetInt("port"))
