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

Mix.env() doesn't work in production or other environments where you use compiled releases (built using Exrm / Distillery) or when Mix just isn't available.

The solution is to specify it in your config/config.exs file:

config :your_app, env: Mix.env()

You can then get the environment atom in your application like this:

Application.get_env(:your_app, :env)
#=> :prod
