Obsidian Bases: tag & link filters, date math, and more file properties
Bases queries now support tag and link filters, date + duration arithmetic, and more file properties — plus an empty query now returns your whole vault.
We've closed several gaps in our Obsidian Bases support, so more of your existing queries now render on your published site exactly as they do in Obsidian.
Query the whole vault by default. A Bases block with no filters now returns every page on your site, matching Obsidian's default — instead of an empty result.
Tag and link filters. You can now filter on tags and links:
filters:
or:
- file.hasTag("book")
- file.hasLink("Reading List")
file.hasTag() matches nested frontmatter tags too — hasTag("book") also matches book/fiction.
Date + duration arithmetic. Formulas can now add and subtract durations from dates:
formulas:
deadline: '(date(start) + "2w").format("YYYY-MM-DD")'
isRecent: 'file.mtime > now() - "1 week"'
Durations support y / M / w / d / h / m / s units, including compound values like "1y2M3d", and the duration() function. Month and year math is calendar-aware.
More file properties. file.mtime, file.ctime, file.tags, file.basename, file.links, and file.backlinks now resolve in filters and formulas — so you can sort by last-modified time, list a note's outgoing links, or count its backlinks.
formulas:
backlinkCount: file.backlinks.unique().length
More of the Bases spec is on the way. See the full Bases documentation for what's supported today.
