I'm planning to build a like/upvote button in my chat app, that has to be real time so I thought I'd do it with socket.io, and I just wanted to know if I have to persist the who liked what data in my database and also show the number of likes on the post, should I do it with two different queries, is there a good article / tutorial on best practice of making a like button.
