Create a list of Connected Clients using socket.io

My advice is to keep track yourself of the list of connected clients, because you never know when the internal API of Socket.IO may change. So on each connect add the client to an array (or to the database) and on each disconnect remove him.

node.js express socket.io

In socket.io@2.3.0 you can use:

Object.keys(io.sockets).forEach((socketId) => {  const socket = io.sockets[socketId];})
