Polka: Expose Polk().close function

[ansarizafar]

Native http has a close() function https://nodejs.org/api/http.html#http_server_close_callback which stops the server from accepting new connections. This is necessary for graceful shutdown of node server.

You have access to the underlying native server.

const app = polka();

// start it at some point
app.listen(PORT);
//~> this is calling 'app.server.listen' under the hood

// shut it down manually
app.server.close();
