How long can a setInterval last in node.js. I need to use it as a cron job. I don't care if the server restarts and resets the interval, important thing is not to stop.
setInterval runs until it is stopped using clearInterval or something forces it like you said a server restart. If the server restarts and resets the interval it just starts again. Have a look at this link here this might help you if you are trying to have a cron job.
