How can I stop nodejs?

Hello. I have started an express+socketio server with the standard:

var app = express();
var server = http.Server(app);
server.listen(3000, () => console.log('listening on *:3000'));

code, but I cannot seem to be able to restart it since I have closed it and reopened. I get

Process crashed with: Error: listen EADDRINUSE: address already in use :::3000
    at Server.setupListenHandle [as _listen2] (net.js:1279:14)
    at listenInCluster (net.js:1327:12)
    at Server.listen (net.js:1414:7)

    at ReadStream.emit (events.js:198:13)

If I change the port then it stars but my client is unable to connect as the old version gets connected. So how could I stop the already running version and start the new one?

After you change the port number, you just have to wait for a while, and then you can go back to the original port.

However, I would recommend that you do not even press the start / restart button unless you are making a change to the server. If you are just changing an express route, a connection, or you change client side, you don't have to restart server. Instead, you should just make a new client, and it should be updated.
