In the end you will have to learn about the Stomp payloads you will be using. The Javascript sends some string msg:

    client.send(roomid, {}, msg);

Net::Stomp also sends some string with ->send.

With Mojo::UserAgent this would likely look like the following, as taken straight from the documentation:

  $ua->start($tx => sub ($ua, $tx) {
    say 'WebSocket handshake failed!' and return unless $tx->is_websoc
+ket;
    $tx->on(message => sub ($tx, $msg) {
      say "WebSocket message: $msg";
      $tx->finish;
    });
    $tx->send('some msg');
  });
