Schedule Nodemailer email based on info in database

I am creating an application that stores events and sends reminder emails to people who signed up 1 hour before the event(the time of each event is stored in the database). At first I was thinking about using CronJobs to schedule these emails, but now I am not sure if that will work. Is there any other node module that will allow me to implement the reminder email functionality.

You can give a try node-schedule. It is using cron-job underneath.

In a quality interval, you can check if there is an upcoming interval, and send the reminder to the appropriate persons.

If you have Redis available to backend it, you might look at something like bull. From the readme:

  • Minimal CPU usage due to a polling-free design.
  • Robust design based on Redis.
  • Delayed jobs.
  • Schedule and repeat jobs according to a cron specification.
  • Rate limiter for jobs.
  • Retries.
  • Priority.
  • Concurrency.
  • Pause/resume—globally or locally.
  • Multiple job types per queue.
  • Threaded (sandboxed) processing functions.
  • Automatic recovery from process crashes.
