Luv is a binding to libuv, the cross-platform C library that does asynchronous I/O in Node.js and runs Node's main loop.
let () =
Luv.DNS.getaddrinfo ~family:`INET ~node:"google.com" ~service:"80" ()
begin fun result ->
let address = (List.hd (Result.get_ok result)).addr in
let socket = Luv.TCP.init () |> Result.get_ok in
Luv.TCP.connect socket address begin fun _ ->
Luv.Stream.write socket [Luv.Buffer.from_string "GET / HTTP/1.1\r\n\r\n"]
(fun _ _ -> Luv.Stream.shutdown socket ignore);
Luv.Stream.read_start socket (function
| Error `EOF -> Luv.Handle.close socket ignore
| Error _ -> exit 2
| Ok response -> print_string (Luv.Buffer.to_string response))
end
end;
