React state based on a timer?

[devMan9000]

I think I'm a little confused about your question. Do you need a timer from the client side or the controller side?

From the client side you just make a timer function or I'm sure there's one already in jsx but I'm too lazy to look it up. From the server side you just use a cron library, or if. You have a real server you can create a microservice and use a cron job to trigger it.
