# config/runtime.exs is executed for all environments, including
# during releases. It is executed after compilation and before the
# system starts, so it is typically used to load production configuration
# and secrets from environment variables or elsewhere. Do not define
# any compile-time configuration in here, as it won't be applied.
# The block below contains prod specific runtime configuration.

# ## Using releases
#
# If you use `mix release`, you need to explicitly enable the server
# by passing the PHX_SERVER=true when you start it:
#
#     PHX_SERVER=true bin/shift73k start
#
# Alternatively, you can use `mix phx.gen.release` to generate a `bin/server`
# script that automatically sets the env var above.

  # ## Configuring the mailer
  #
  # In production you need to configure the mailer to use a different adapter.
  # Also, you may need to configure the Swoosh API client of your choice if you
  # are not using SMTP. Here is an example of the configuration:
  #
  #     config :shift73k, Shift73k.Mailer,
  #       adapter: Swoosh.Adapters.Mailgun,
  #       api_key: System.get_env("MAILGUN_API_KEY"),
  #       domain: System.get_env("MAILGUN_DOMAIN")
  #
  # For this example you need include a HTTP client required by Swoosh API client.
  # Swoosh supports Hackney and Finch out of the box:
  #
  #     config :swoosh, :api_client, Swoosh.ApiClient.Hackney
  #
  # See https://hexdocs.pm/swoosh/Swoosh.html#module-installation for details.
