How to consume a Tesla.Adapter.Finch stream body response

[pau-riosa]

Is there any documentation how to consume a stream body coming from Tesla.Adapter.Finch?

I'd like to consume a stream data and create a wav file from it.

Could you do something like,

defmodule AudioStreamer do
  def client do
    Tesla.client([
      {Tesla.Middleware.BaseUrl, "https://audio-service.com"}
    ], {Tesla.Adapter.Finch, name: MyFinch})
  end
  
  def stream_to_wav_file(audio_url, output_path) do
    case Tesla.get(client(), audio_url, opts: [adapter: [response: :stream]]) do
      {:ok, %Tesla.Env{body: stream}} ->
        File.open!(output_path, [:write, :binary])
        |> write_stream_to_file(stream)
        |> File.close()
        
        {:ok, output_path}
      
      {:error, reason} ->
        {:error, reason}
    end
  end
end
