Streaming Response

[leifg]

According to the README, Tesla supports streaming if the underlying adapter supports it.

From the code and the examples I found it seems though that streaming means in this instance, streaming of the request.

I am interested in how I would be able to stream the response of a request (very useful for something like large downloads).

Is this supported, if so: how?

Unfortunately streaming response body is not implemented, but it could be done. I can imagine something like:

case Tesla.get(client, "/stream", stream_response: true) do
  {:ok, env} -> # on successful read of status & headers env.body is a Stream
  {:error, reason} -> # ...
end

I'd go with Tesla.get(client, "/path", response: :stream) (instead of stream_response: true)
