Is there any way to configure Redis to delete data after some time?

Question

Redis

Hello. I'm using the standard Redis module for Node.js ( https://github.com/NodeRedis/node_redis). The data is stored in hash arrays. Are there any standard methods that allow you to set up automatic deletion of a key if it has not been written to for n minutes?
Ideally, I would also like to hang a handler on this event
