## Description

You may notice that up to now you have only been increasing the user count. Handling a user disconnecting is just as easy as handling the initial connect, except you have to listen for it on each socket instead of on the whole server.
|
||||
|
||||
To do this, add another listener inside the existing <code>'connect'</code> listener that listens for <code>'disconnect'</code> on the socket with no data passed through. You can test this functionality by just logging that a user has disconnected to the console.
|
||||
|
||||
```js
|
||||
socket.on('disconnect', () => {
|
||||
/*anything you want to do on disconnect*/
|
||||
});
|
||||
```
|
||||
|
||||
To make sure clients continuously have the updated count of current users, you should decrease the currentUsers by 1 when the disconnect happens then emit the 'user count' event with the updated count!
|
||||
|
||||
<strong>Note:</strong> Just like <code>'disconnect'</code>, all other events that a socket can emit to the server should be handled within the connecting listener where we have 'socket' defined.
