go-env

Tired of writing the same env helpers over and over again? Yeah. me too. That's why this repo exists.

Installation

go get github.com/herzrasen/go-env

To get an error when no environment variable key exists:

import "github.com/herzrasen/go-env/env"

v, err := env.GetOrError("FOO")
if err != nil {
	return err
}
fmt.Printf("%s", v)

To either load the environment variable or use a default value:

import "github.com/herzrasen/go-env/env"

v := env.GetOrElse("FOO", "baz")
fmt.Printf("%s", v)
