How do I really secure my enviroment variables.

[untold fox]

Hello, new to Next js and I'm building a project that includes an API and supabase. I read that interacting with the database in a "use client" file exposes the enviroment variables and would lead to hacks basically and that I should use ssr. The thing is, I'm using states on most of my files where I need to fetch stuff aswell, Idk how to work around this hurdle really, resources online are not helping. I'd appreciate someone who explains it like I'm 4 🙏
