#### Time is of the essence.
```c++
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) {
return largeFile.substr(offset);
}, fileSize);
}).onPost("/upload/:filename", [](auto *s, auto *req, auto *args) {
s->read([std::ofstream fout = args[0]](int offset, auto chunk) {
fout << chunk;
});
}).onWebSocket<UserData>("/wsApi", [](auto *ws, auto *req, auto *args) {
std::cout << "WebSocket connected to /wsApi" << std::endl;
}).onMessage([](auto *ws, auto message, auto opCode) {
ws->send(message, opCode);
}).onClose([](auto *ws, int code, auto message) {
std::cout << "WebSocket disconnected from /wsApi" << std::endl;
}).listen("localhost", 3000, 0);
```
