#include <uWS/uWS.h>
using namespace uWS;

int main() {
    Hub h;
    std::string response = "Hello!";

    h.onMessage([](WebSocket<SERVER> *ws, char *message, size_t length, OpCode opCode) {
        ws->send(message, length, opCode);
    });

    h.onHttpRequest([&](HttpResponse *res, HttpRequest req, char *data, size_t length,
                        size_t remainingBytes) {
        res->end(response.data(), response.length());
    });

    if (h.listen(3000)) {
        h.run();
    }
}

Excel across the board.

Fast does not imply broken.

Gracefully passes the entire Autobahn fuzzing test suite with no failures or Valgrind/ASAN errors. With or without SSL/permessage-deflate.
