Limit one vote per day in MERN stack appliction

Question

I am using the MongoDB database and node.js as the backend. I want to implement a voting system where a user after logging in to my website and can vote on certain things. But I want to make sure that they can make only one vote per day. How can I implement this?

A possible solution that I thought of:-

Store the latest vote timestamp and then check when he tries to vote again weather a day has passed or not. But this is not perfect as it means there should be a gap of 24 hrs between two votes irrespective of the time of the day he votes in.

Could someone suggest something better than I can implement in node.js and MongoDB?

Thanks in advance.

Answer 1

Id use Redis with ttl for this and on a middleware I would check if the user already voted(exists in the Redis). But if you dont use Redis you can also use TTL on mongoDB, so Id create a schema for this and check on every request in middleware.
