You can implement this feature by keeping track of the number of users who connect to your application using socket.io.
There are a few steps involved in implementing this feature:
let usersOnline = 0;
io.on('connection', socket => {
// Increment the counter variable
usersOnline++;
socket.on('disconnect', () => {
// Decrement the counter variable
usersOnline--;
});
});
io.on('connection', socket => {
usersOnline++;
io.emit('user count', usersOnline);
socket.on('disconnect', () => {
usersOnline--;
io.emit('user count', usersOnline);
});
});
socket.on('user count', count => {
document.getElementById('user-count').innerText = `Users online: ${count}`;
});
This code assumes that there is an element on the client side with an id of "user-count" that you can update with the current user count.
By implementing these steps, you should be able to display the count of users that are currently online in your chat application.
