file_config

This library provides a way to load configuration from a file and reload it when it changes. The native format is the Erlang binary term format, but it also supports CSV and can be extended to support other formats.

Add file_config to your list of dependencies in mix.exs:

def deps do
  [
    {:file_config, "~> 0.7.1"}
  ]
end
