It’s quite ironic that you are pointing out I still need PHP to run … PHP. Whereas if I download a Go binary, then I won’t.
Well, I can do you one better — you can compile the entire server and PHP code to a binary, as it says in the README, so you won’t need ANYTHING once you download that LOL.
Also, since you wrote that comment, I also added supports for websockets (wire-compatible with socket.io) and rooms, all of it with the same approach: put files in folders and it “just works”. What is so bad about that?
