Why?

We needed a way of checking that environment variables were defined and improving the developer experience when they are not.

What?

envar is our solution to a very specific problem: the developer experience when a required environment variable is undefined.

How?

Installation

Install the package by adding envar to your list of dependencies in your mix.exs file:

def deps do
  [
    {:envar, "~> 0.1.0"}
  ]
end

Research

We created this module after doing a comprehensive search of the Elixir (Hex.pm) ecosystem, see: dwyl/learn-environment-variables/issues/18
