Ok so I have this Tetris game on my portfolio which is hosted on vercel. Now I want to have a basic leaderboard by which like I can save highscores. But I don't really want to setup an entire pocketbase db for this. I do have a MySQL server setup on my vps. But is there any easy way to like just save it in a json file? Due to vercel I can't just write to their filesystem so was open to any ideas :)
