gh-action-data-scraping VS scrape-san-mateo-fire-dispatch

i do this as a demo: https://github.com/swyxio/gh-action-data-scraping

but conveniently it also serves as a way to track the downtime of github actions, which used to be bad but seems to be fine the last couple months: https://github.com/swyxio/gh-action-data-scraping/assets/676...

Git is a key technology in this approach, because the value you get out of this form of scraping is the commit history - it's a way of turning a static source of information into a record of how that information changed over time.

I think it's fine to use the term "scraping" to refer to downloading a JSON file.

These days an increasing number of websites work by serving up JSON which is then turned into HTML by a client-side JavaScript app. The JSON often isn't a formally documented API, but you can grab it directly to avoid the extra step of processing the HTML.

I do run Git scrapers that process HTML as well. A couple of examples:

scrape-san-mateo-fire-dispatch https://github.com/simonw/scrape-san-mateo-fire-dispatch scrapes the HTML from http://www.firedispatch.com/iPhoneActiveIncident.asp?Agency=... and records both the original HTML and converted JSON in the repository.

scrape-hacker-news-by-domain https://github.com/simonw/scrape-hacker-news-by-domain uses my https://shot-scraper.datasette.io/ browser automation tool to convert an HTML page on Hacker News into JSON and save that to the repo. I wrote more about how that works here: https://simonwillison.net/2022/Dec/2/datasette-write-api/
