robertklep s answer to check socket connected is correct except for reconnect event  https   socket io docs client-api  event-reconnect As the document said it is  Fired upon a successful reconnection    but when you check socket connected then it is false   Not sure it is a bug or intentional

Track the state of the connection yourself  With a boolean  Set it to false at declaration  Use the various events  connect  disconnect  reconnect  etc   to reassign the current boolean value  Note  Using undocumented API features  e g   socket connected   is not a good idea  the feature could get removed in a subsequent version without the removal being mentioned

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
