Config

Simple configuration

Why:

Every single program uses configuration in the form of settings or env vars

How:

environment.config.json

{
  "name": "hi",
  "app": {
    "port": "3000",
    "maxRequests": 1.2
  }
}

golang struct:

type AppSettings struct {
	Port        string
	MaxRequests float64
}

// Settings contains the config.yml settings
type Settings struct {
	// App
	Name string      `mapstructure:"name"`
	App  AppSettings `mapstructure:"app"`
}

Note: Avoid using underscores and stick to using camelCase. Instead of max_requests use maxRequests.
