# and secrets from environment variables or elsewhere. Do not define

# The block below contains prod specific runtime configuration.
# Start the phoenix server if environment is set and running in a release

# ## Using releases
#
# If you are doing OTP releases, you need to instruct Phoenix
# to start each relevant endpoint:
#
# config :demo, DemoWeb.Endpoint, server: true
#
# Then you can assemble a release by calling `mix release`.
# See `mix help release` for more information.
# ## 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 :demo, Demo.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.
