I made NMB(a.k.a. No Meaning Button), a global button with no real purpose. Every click increases a shared counter and triggers random visual effects.
I originally used Firebase, but switched to Supabase during development. The most challenging part was rebuilding the global counter and real-time synchronization. I’m pround that the final project stayed simple but fun.
To test it, just press the button. There is no goal or reward. That’s the point.
