This repository contains the logic for creating web push notifications describing the current emission intensity forecast to all users currently subscribed to notifications.
In order to send messages, we need to specify an email address for the subscriber; i.e. the administrative contact of the push message, as well as a VAPID private key corresponding to the public key used when new recipients are subscribed.
The simplest way to run the script is to use Docker, specifying all configuration parameters as environment variables, and a Docker volume containing the database of subscriptions.
docker build -t groenstroem-web-push .
docker run -v some_volume:/data -e SUB_EMAIL=mail@example.com -e VAPID_KEY=... groenstroem-web-push
