QRCode - Implement QR Code in Elixir

You can use for example request for json.
For example:

defmodule MyAppWeb.Controllers.ExampleController do
  def action_name(conn, %{param_name: param_value}) do
    matrix = QRCode.encode(param_value).matrix
    data = matrix |> Tuple.to_list() |> Enum.map(&Tuple.to_list/1)
    json(conn, data)
  end
end
