import Config

# 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/microwaveprop start
#
# Alternatively, you can use `mix phx.gen.release` to generate a `bin/server`
# script that automatically sets the env var above.

  # ## SSL Support
  #
  # To get SSL working, you will need to add the `https` key
  # to your endpoint configuration:
  #
  #     config :microwaveprop, MicrowavepropWeb.Endpoint,
  #       https: [
  #         ...,
  #         port: 443,
  #         cipher_suite: :strong,
  #         keyfile: System.get_env("SOME_APP_SSL_KEY_PATH"),
  #         certfile: System.get_env("SOME_APP_SSL_CERT_PATH")
  #       ]
  #
  # The `cipher_suite` is set to `:strong` to support only the
  # latest and more secure SSL ciphers. This means old browsers
  # and clients may not be supported. You can set it to
  # `:compatible` for wider support.
  #
  # `:keyfile` and `:certfile` expect an absolute path to the key
  # and cert in disk or a relative path inside priv, for example
  # "priv/ssl/server.key". For all supported SSL configuration
  # options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1
  #
  # We also recommend setting `force_ssl` in your config/prod.exs,
  # ensuring no data is ever sent via http, always redirecting to https:
  #
  #     config :microwaveprop, MicrowavepropWeb.Endpoint,
  #       force_ssl: [hsts: true]
  #
  # Check `Plug.SSL` for all available options in `force_ssl`.

  # ## Configuring the mailer
  #
  # In production you need to configure the mailer to use a different adapter.
  # Here is an example configuration for Mailgun:
  #
  #     config :microwaveprop, Microwaveprop.Mailer,
  #       adapter: Swoosh.Adapters.Mailgun,
  # tls: :always + explicit tls_options is required — SMTP2GO's endpoint sits
  # behind a wildcard cert (*.smtp2go.com) so SNI is mandatory, and gen_smtp
  # won't set it without explicit server_name_indication. Without this, the
  # handshake fails with an "unexpected_message" TLS alert.
  email_server = System.get_env("EMAIL_SERVER")
