hackernewsalerts-backend

The backend services for hackernewsalerts.com. A web application that sends email notifications when someone replies to one of your comments or posts on Hacker News.

Link to the frontend.

Architecture

I run 2 Python Django services:

• A Django Ninja REST API that handles email signups - see views.py
• A Django Q2 scheduled worker that checks for updates and sends emails when necessary - see tasks.py

Both services use the same Postgres database backend, and are deployed with CapRover - see the captain-definition JSON files.

Commands

See Makefile

TODO

• ALLOWED_HOSTS and CORS_ALLOWED_ORIGINS in prod should only allow for frontend prod

Notes

The scheduled worker sends email alerts to the admin user every time there's a failure. I sometimes get these alerts because of missing data, but the data usually becomes available after a couple of hours.
