accessing socket outside the socket.on('connection') closure

Question

Below is part of app.js, it has socket connection with client

io.sockets.on('connection', function (soc) {
    soc.emit('news', { status: 'connected' });
});

What I want to do is access the soc var outside the connection closure, like this

io.sockets.on('connection', function (soc) {
        do something magical here so I can access soc from outside
});
soc.emit('news', { status: 'connected' });

What additional technique need to add in to archive this structure?

Answer 1

you need to reference your socket io variable in your server code:

io.sockets.emit('news', { status: 'connected' });

so in your sample code, it could look something like this:

io.sockets.on('connection', function (soc) {
    emit();
});

function emit(){
    io.sockets.emit('news', { status: 'connected' });
}
