The "By Date" library node was decorative. Now it's a real
hierarchical navigator: expand to see year buckets (with photo
counts), expand a year to see its months, click any year or
month to filter the timeline to that date range.
Backend
- New GET /library/date_buckets aggregates non-discarded photos
by year+month from Photo.taken_at via SQLite strftime, returning
[{ year, count, months: [{ month, count }] }] sorted newest-
first. NULL taken_at rows are excluded.
Frontend
- New library.dateBuckets() helper + DateBucketYear / Month types.
- New hooks/useDateBucketsQuery.ts with a 60s staleTime.
- LeftSidebar builds the By Date subtree dynamically from the
query: each year is a tree node with month children. Year nodes
use the Calendar icon, months render as their full English name.
- applyLibraryNode handles two new id prefixes:
'date-year-{year}' → setDateFrom YYYY-01-01, setDateTo YYYY-12-31
'date-month-{Y}-{M}'→ setDateFrom YYYY-MM-01, setDateTo YYYY-MM-LL
where LL is the last day of the month (computed via Date trick
new Date(year, month, 0).getDate() — uses month-day=0 to roll
back into the previous month's last day).
- isItemActive recognises when the current dateFrom/dateTo matches
a year or month node so the sidebar selection highlight stays
in sync with the filter store (also when filters are set
externally via the filter bar or URL hydration).
