Al conectar un usuario

export const connectUser = (client: Socket, io: socketIO.Server) => {
    numberUser++;
    const user = new User(client.id, 'user-' + numberUser);
    console.log('User connected:    ' + user.name + ' -> ' + client.id);
    connectedUsers.addUser(user);

    io.emit('active-users', connectedUsers.getList());
};
