Modern Systems Programming with Scala Native

Integrations and Ecosystems

Now, we finally have all the pieces of the puzzle. Over the last several chapters, we’ve accumulated a wide range of capabilities based around libuv’s event loop for a full asynchronous programming environment.

curl

Since our curl client provides results as a Future[HttpResponse], it’s straightforward to plug in to our async request handler pattern:

def main(args:Array[String]):Unit = {
  Service()
    .getAsync("/fetch/example") { r =>
      Curl.get(c"https://www.example.com").map { response =>
        Response(200,"OK",Map(),response.body)
      }
    }
  uv_run(EventLoop.loop, UV_RUN_DEFAULT)
}

This makes writing a straightforward proxy server trivial. But we can make it even cleaner if we write some boilerplate to convert the ...
