Config 📃

Easily handle JSON and environment based config in one go.

Example

// Define your projects configuration.
// 
// Validation is handled by https://github.com/go-playground/validator
type OurConfig struct {
    FromJSON string `json:"from_json" validate:"required"`
    FromEnv  string `env:"FROM_ENV" validate:"required"`
}

// Specify where to find your projects configuration files.
var cfg OurConfig
err := config.NewFromFile(&config.Config{
    Path:        "./config",
    Environment: config.Local,
}, &cfg)

// If there were no validation errors cfg will now be populated with values from 
// the local JSON file as well as the environment.
