My first attempt on using this pattern is by scraping the "Gelbe Karten" from the Stuttgart website. The code is on Github: https://github.com/mfa/gelbekarten_stuttgart.
Github Actions can be triggered by a cron schedule, for example:
This yaml triggers every hour on minute 23. An important note here: the Actions don't run exactly on that minute. The Action is scheduled and runs when there are enough workers available. The full code of the Action: https://github.com/mfa/gelbekarten_stuttgart/blob/main/.github/workflows/scrape.yml.
The git log shows the updates of the website as commits on the csv file: https://github.com/mfa/gelbekarten_stuttgart/commits/main/data/gelbe_karten_stuttgart.csv.
