feat: canonicalize old-version example pages to /latest by KevinVandy · Pull Request #1166 · TanStack/tanstack.com · GitHub

Follow-up to #1143 — example pages were missed in the original scope and still self-canonicalized on old versions.

Old-version example pages now emit <link rel="canonical"> (and matching og:url/twitter:url) pointing at their /latest equivalent, same as docs pages
Existence check asks whether examples/{framework}/{slug} exists on the latest branch via the cached repo-contents lookup, resolved in parallel with the example fetch; fails open to a self-canonical
Latest pages short-circuit before any I/O (branch comparison), and the v# → /latest 308 from feat: redirect latest v# to /latest and canonicalize old-version docs #1143 already covered examples via the $version parent route
The route takes canonical ownership via staticData.ownsCanonicalLink, so the root suppresses its default self-canonical and exactly one tag renders

Summary by CodeRabbit

SEO Improvements
- Updated example pages to provide accurate canonical URLs when newer versions are available.
- Enhanced Open Graph and Twitter metadata to use the appropriate canonical page URL.
- Prevented duplicate social sharing URLs when a page defines its own canonical link.
- Preserved existing page metadata while improving search visibility and social sharing behavior.
- Improved consistency of canonical URL handling across documentation pages.

Example pages now get the same treatment as docs pages: when serving an old version, check whether the same example directory exists on the latest branch (cached repo-contents lookup, resolved in parallel with the example fetch, fails open) and emit a rel=canonical (plus og:url/twitter:url) pointing at the /latest URL. The route takes over canonical ownership via staticData.ownsCanonicalLink like the docs routes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The framework example route checks for matching examples on the latest branch. It propagates a canonical path override through loader data and uses it for canonical, Open Graph, and Twitter metadata. The root route avoids duplicate URL metadata.

Changes

Framework example canonicalization

Layer / File(s)	Summary
Latest example resolution src/routes/_library/$libraryId/$version.docs.framework.$framework.examples.$.tsx	The loader checks for latest-branch equivalents. The lookup skips latest or unchanged branches, handles missing directories, and fails open on fetch errors.
Canonical metadata output src/routes/_library/$libraryId/$version.docs.framework.$framework.examples.$.tsx	Loader results include the canonical path override. The route owns the canonical link and emits canonical, Open Graph, and Twitter URLs.
Root metadata coordination src/routes/__root.tsx	The root route omits Open Graph and Twitter URL metadata when a matched route owns the canonical link.

Estimated code review effort: 3 (Moderate) | ~20 minutes

og:url and twitter:url metadata whenever ownsCanonicalLink is true, so the
loader-owned canonicalHref remains the sole URL metadata source. Preserve the
existing canonical link behavior and the page-level tags in the example route.
