How do I track how many people online on my website like freecodecamp online indicator?
The app is a chatroom. Users have to sign in to use the chatroom. So the application
can always know how many users there are because it’s just a simple count.
You can google
keep track of online users API. What I saw with 1 min search is, using session table and linking it back to user. I bet you can find a lot more!
