configo

configo

Definitive configuration utility in Golang

What

configo gathers configuration parameters from variety of sources,
overlays values by a different env -- production, development, etc -- and merges into a single struct.

Features

It's a set of popular libraries.

• Read from environment vars / dotenv file and bind them into struct
  • https://github.com/joho/godotenv
  • https://github.com/kelseyhightower/envconfig
• Read from YAML files
  • https://github.com/ghodss/yaml
• Finally, validate the struct
  • https://github.com/asaskevich/govalidator

Examples

Env vars:

export APP_ENV=production

Dotenv file:

# .env

APP_FOO=foo

Config yaml files:

# config/default.yml

Bar: default
Baz: default?

# config/production.yml

Baz: production

And your config struct...

type Config struct {
	Env string
	Foo string
	Bar string
	Baz string
}

c := Config{}
configo.Load(c, configo.Option{Dir: "./config"})

c.Env //=> "production"
c.Foo //=> "foo"
c.Bar //=> "default"
c.Baz //=> "production"
