feat: add push notifications #1704

aarushtools · 2024-07-30T19:52:12Z

Proposed changes

add the ability to send push notifications via webpush
tests for notifications and pages to view notification logs and send a custom one
adds user push notification preferences and implements sending push notifications on announcements, absences, glance, etc. (eighth waitlist push notification option is implemented in the preferences model but unused)

Brief description of rationale

Many of Ion's current notification features rely on sending emails but people check push notifications more often. This makes the PWA experience more intuitive especially on mobile

Notes

In production, the VAPID keys (generated via create_vapid_keys.py) should be generated once and never changed, otherwise all push subscriptions will be invalidated and users will have to manually subscribe to push notifications again

This is great!!! Are you all done or still working on stuff?
One useful notification option to add is when your bus arrives you get sent a notif, and also maybe some text description of where it's parked (e.g. "in front of the curb," "right front row", "left back row"). Maybe those notifs have to be delayed so they aren't sent until the end of the day (4 pm most days, but dynamically calculated for early release). And also maybe a notif that sends at 4 pm "your bus isn't here yet" if it hasn't arrived.

great work!!

Everything is done, I'll try adding that feature 👍

I added it, here's what it looks like:

and the bus spot id -> string translations:

On mobile, on preferences the subscribe page looks too transparent, can you decrease the opacity there?
It doesn't work on Edge, right? I can subscribe now actually, but I don't get notified. If that's right, please include a note to the user about that, and also a decent number of people use Edge so getting support for it would be good.
There's a notification sound on mobile - can you turn off the sound? I don't think people will like that.
Can you make Django admin interfaces for the webpush-related models?
Does the bus notification only check at 4 pm right now? Can you do something where if the bus hasn't arrived at 4 pm, send the bus delayed notification you're already doing, then when the bus does arrive send another notification saying so?

@alanzhu0 everythings done 👍
