Get current environment name

Question

In Phoenix Framework, how can I get the current environment\'s name ?

I\'ve already tried reading env variables with System.get_env(\"MIX_ENV\")

Answer 1

An alternative to putting the Mix.env/0 into your applications configuration is to use a module attribute. This also works in production because module attributes are evaluate at compile time.

defmodule MyModule do
  @env Mix.env()

  def env, do: @env
end

If you only need the environment in a specific place - for example when starting up the application supervisor - this tends to be the easier solution.
