Question

How can i detect server status ?

var socket= io.connect(\'http://nodeserver.com:3000\');

Here is my code. If nodeserver.com:3000

Answer 1

have you tried doing it like this?

this.socket.on('connect_error', function (err) {
    //do something
});

in other words, use the connect_error instead of the connect_failed event?

Answer 2

for checking "disconect" of a socket you can you this code :

io.socket.on('connect', function(){
  console.log('connected to server ...');

});

io.socket.on('disconnect', function(){
  console.log('Lost connection to server');
});
