Funny pipe code

Hi all, first post here (also a newbie in elixir/FP).
So, I have next pipe code which works but also looks funny:

case {status_code, body} do
      {200, _} ->
        edges = Poison.Parser.parse!(body)
        |> Map.get("data")
        |> Map.get("repository")
        |> Map.get("issues")
        |> Map.get("edges")
        if Enum.count(edges) == 0 do
          :ok
        else
          edges
          |> Enum.at(-1)
          # get last edge cursor
          |> Map.get("cursor")
          |> IO.inspect
          # recurse to get next page
          |> get(pagenum + 1)
          :ok
        end
      _ ->
        IO.inspect(status_code)
        IO.inspect("[ERROR]")
        :error
    end

2 questions here:

  1. How can I avoid using the temp var edges (i.e. use a continuous pipe)
  2. Is there some sort of tee operator that I could use to siphon out data at a specific pipe point whilst the pipe would continue on?

Thanks!
