uWS::App a; // or uWS::SSLApp(options) for SSL

a.onGet("/", [](auto *s, auto *req, auto *args) {

    s->writeStatus("200 OK")->writeHeader("Hello", "World")->end(buffer);

}).onGet("/largefile", [](auto *s, auto *req, auto *args) {

    s->write([](int offset) {
        // stream chunks of the large file
    }, fileSize);

}).onPost("/upload/:filename", [](auto *s, auto *req, auto *args) {

    s->read([std::string filename = args[0]](int offset, auto chunk) {
        // stream chunks of data in to database with filename
    });

}).onWebSocket("/wsApi", [](auto *protocol) {

    protocol->onConnection([](auto *ws) {

        // store this websocket somewhere

    })->onMessage([](auto *ws, auto message, auto opCode) {

        ws->send(message, opCode);

    })->onDisconnection([]() {

        // remove this websocket

    });

}).listen("localhost", 3000, 0);
