One pattern that has become quite common at GitHub, for me, is using Actions to spot if something has changed. I use this to track changes in project boards, or changes in JSON payloads, changes in websites… basically anything out there.
The basic anatomy is:
- Have a workflow file that runs on a schedule
- Create a data file in your repository to store the data, for example in JSON or CSV.
- The workflow loads the data file from the previous time.
- Loads the data from the source, probably with a bit of massaging to get it just right.
- Compare the two.
- Send any changes to a slack channel.
- Save the data file.
- Commit the data file.
Then next time it runs, it just repeats the process. I wrote one recently to notify GitHub staff internally when a job gets posted to our external job board and its 85 lines of Python that we whipped up in an hour.
Please note: there is an Acceptable Use policy for GitHub and if you do this alot you might hit that.
