Database?

I don't actually need a database b/c I can just store the votes in memory for a real-time poll. But what if I want to restart the server and not lose the votes? Currently I'm using nedb just as a simple beginner-friendly database example, please add your suggestions and thoughts to this thread!

This is an unresolved design discussion rather than a scoped implementation task. Review the current vote-storage path and how nedb is being used, then clarify whether restart persistence is required and which approach the project will support; the work is done only after that decision is recorded and its persistence behavior is defined.
