Stop socket.io from reconnecting

Question

Simple scenario:

1. Client connects to server with socket.io (socket = io.connect(...))
2. Server crashes
3. Client tries to reconnect

Answer 1

You might want to handle the reconnection yourself.

// Disables the automatic reconnection
var socket = io.connect('http://server.com', {
    reconnection: false
});

// Reconnects on disconnection
socket.on('disconnect', function(){
    socket.connect(callback);
});

Note: old versions used reconnect instead of reconnection.
