This is an RSS-to-email system that periodically checks one or more RSS feed and sends new items to a list of emails. Every feed has a list of emails associated.
Every feed gets its own feed-id@feedsubscription.com email address. The default frequency is hourly now, but any cron-like schedule is supported.
There is also an API which can be inspected in src/api/server.ts.
Everything is packaged and deployed as a Docker composition: in
docker-compose.yml.
The app stores data in the DATA_DIR_ROOT directory:
/settings.json
