Question

Simple scenario:

1. Client connects to server with socket.io (socket = io.connect(...))
2. Server crashes
3. Client tries to reconnect
4. User tells client to disconnect (socket.disconnect())
5. Server starts
6. Client reconnects

It seems that once socket.io starts attempting to reconnect, it cannot be stopped anymore. I want step 4 to prevent step 6 from happening, but it doesn’t. What do I have to call instead?

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.
