I want to do something when the nodejs server is started or I will do something else not related to the server.
But how could I know that. There is no property that shows the status of the connection, and because the socket is asynchronous that I can't get the err by try..catch...
The following is my clinet code.
var socket = io.connect('http://localhost:3000/monitor');
socket.on('message', function (data) {
console.log(data);
});
Anyone can tell me how to if(is connected).. else.. in this place?
Try listening to the following events:
socket.on( 'connect', function() {
});
socket.on( 'disconnect', function() {
});
socket.on( 'connect_failed', function() {
});
socket.on( 'error', function() {
});
Socket.io has some bugs in firing some events so it's better to listen to all of those that might mean a connection failed.
