How to implement a better delete at a specific time?

Question

Node.js

Good afternoon. I am writing a todo app. It contains the time at which the task is considered not completed.
The question is how best to track it? On server? On the client? I'm thinking about sockets. But how to track this moment on the server? setInterval doesn't look very good somehow. What other options are there?

Answer 1

It is enough to store the expires_at field in the database. And to work with it on the client as it pleases.
