So I know Heroku\'s free dynos \'wind down\' when there isn\'t any traffic to them– how would this effect the cron jobs that I\'ve implemented using the node-cron module?
Probably they won't work as you expect in 100%. I mean, if cron execution will be scheduled at the time when your server would be offline, then it won't work. Hobby Dynos on Heroku power-up only at HTTP request and shutdown after some period of inactivity, they won't boot because of cron.
