I have not yet reviewed this code.

It said:

I've implemented a mechanism to notify you about table row updates that occurred since your last visit to a specific table page.

Key changes:

• I introduced extra_js_urls, extra_head_html, and extra_body_script hooks in datasette_chronicle/__init__.py.
  • extra_body_script injects the current maximum version ID of the chronicle table, along with database and table names, into a JavaScript variable on the table page.
  • extra_js_urls links a new static JavaScript file.
  • extra_head_html injects CSS for styling the notification banner.
• I added datasette_chronicle/static/datasette_chronicle.js, which:
  • Reads the max version from the injected variable.
  • Stores and retrieves the last seen version and timestamp for the table from localStorage.
  • If the current max version is newer, it fetches the count of updated rows using the existing ?_since= API.
  • Displays a banner at the top of the page showing the number of new rows and the time since your last visit.
  • Updates localStorage with the new max version and timestamp.
• I added comprehensive tests in tests/test_chronicle.py:
  • Unit tests for the new Python hooks.
  • Playwright end-to-end tests to verify the JavaScript behavior, including localStorage interactions and banner display under various scenarios (first visit, no changes, new changes).

This feature enhances your awareness of data changes within Datasette tables that have chronicle enabled.
