Access project version within elixir application

Question

I have an elixir project with a defined version. How can I access this from within the running application.

in mix.exs

  def project do
    [app: :my_app

Here's a similar approach to retrieve the version string. It also relies on the :application module, but is maybe a bit more straightforward:

{:ok, vsn} = :application.get_key(:my_app, :vsn)
List.to_string(vsn)
