I receive GET requests on my localhost:3000 from socket.io, but I've never used it

Hey! If I run something on localhost:3000, I always get these socket.io requests on my terminal:

I don't know what can be the reason, I've never even heard about socket.io, thought maybe someone could help. It's probably coming from my computer, but I have no idea from where, as I mentioned, I never used socket.io, didn't imported it or downloaded it. The issue occurs only on localhost:3000, other ports not affected

Hi! That's weird indeed. Did you check if the HTTP request comes with an origin header?
