Asynchroneous answer to the client with nodejs and socket.io... is it possible?

[Bouch Seb]

Hi, thanks for reading my newbie question. Sorry if it's already in the forum and I didn't find it...
Is it possible to have this sequence with nodejs through socket.io:
1. a client requests the server
2. the server answers and runs a setTimeout function
3. when the setTimeout elapses, the server sends another answer to the client
Easy?
Thanks in advance for your answer.

Yes, it is, it's quite easy, if your socket connection persists (or your server and client have means to reconnect if the socket is short-lived).

Example would be something like this:

```

io.on('connection', function(socket){

  socket.on('message', function(msg) {

  })

});

```
