Join Alex Banks for an in-depth discussion in this video Handling disconnects, part of Building a Polling App with Socket IO and React.js.
- At present we don't know how many sockets…we have connected, and if a socket disconnects…we're not indicating that status to the user.…We need to keep track of our socket connections…and indicate to the user when the socket has disconnected.…To get started doing this work…we're going to go ahead and open up our app-server file.…In our app-server file the very first thing we're going…to do is create a variable to store all of our connections.…Down here on line four…I'm going to create a variable called connections…and I'm going to set that to an array.…
