Scheduled WebPush Notifications

[AdrianAndersen]

It would be great to implement functionality to be able to schedule push notifications sending so that non-Slack peeps can get scheduled reminders for classes as well.

It does not seem like WebPush has scheduling built in, so we have to handle the scheduling ourselves. I envision this as a cron service, where we create jobs that are used to schedule certain reminders for users.

This functionality would also warrant an upgrade to the notification settings granularity. Would be neat to split up the types of notifications a user can get so that it can enable or disable the types of notifications they want. Notification categories could look like this:

• Master toggle (activate the web push subscription)
• Important notifications (booking or authentication errors, system downtime, etc)
• Booking notifications
• Booking reminders
• Friend Requests
• Friends who book/unbook classes that you have also booked
• Friends activity (get notified when certain friends book classes, maybe only selected friends that you "follow")

If we implement this functionality for WebPush, I would argue that we could drop the Slack dependency since you would get all the info you need about friends' activity natively in rezervo.
