Installation

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

def deps do
  [{:artifact, "~> 0.1.0"}]
end

Setup in 1-2-3

Define a module and use Artifact:

defmodule ImageUploader do
  use Artifact, otp_app: :my_app
end

Add the supervisor to your supervisor tree:

def start(_type, _args) do
  import Supervisor.Spec, warn: false

  children = [
	 supervisor(ImageUploader.Supervisor, [])
  ]

  opts = [strategy: :one_for_one, name: MyApp.Supervisor]
 Supervisor.start_link(children, opts)
end

Update your router to include the generated plug:
