Get connection status on Socket.io client

Question

I'm using Socket.io, and I'd like to know the status of connection to the server from the client-side.

Something like this:

socket.status // return true if connected, false otherwise 

I need this information to give a visual feedback to the user if the connection has dropped or it has disconnected for any reason.

Answer 1

You can check the socket.connected property:

var socket = io.connect(); console.log('check 1', socket.connected); socket.on('connect', function() {   console.log('check 2', socket.connected); }); 

It's updated dynamically, if the connection is lost it'll be set to false until the client picks up the connection again. So easy to check for with setInterval or something like that.

Another solution would be to catch disconnect events and track the status yourself.

Answer 2

You can check whether the connection was lost or not by using this function:-

var socket = io( /**connection**/ ); socket.on('disconnect', function(){ //Your Code Here }); 

Hope it will help you.
