Vert.x httpClient/webClient process response chunk by chunk or as stream

I have application with vert.x and asyncHttpClient. I want to replace asyncHttpClient with vert.x httpClient (webClient), but i need to have ability to process response by chunks or by small parts of data (like org.asynchttpclient.AsyncHandler in AsyncHttpClient) or like a stream. Is it possible? I look at custom BodyCodec, but i can`t understand data flow in custom WriteStream.

You can't do this easily with Vert.x Web Client which is designed for buffering responses.

However you can do this with the Vert.x Http Client:

client.request(HttpMethod.GET, "some-uri", ar1 -> {

  if (ar1.succeeded()) {
    HttpClientRequest request = ar1.result();
    request.send(ar2 -> {
      HttpClientResponse response = ar2.result();
      response.handler(buffer -> {
        System.out.println("Received a part of the response body: " + buffer);
      });
    });
  }
});
