fix(seo): canonicalize library landing pages to /latest by KevinVandy · Pull Request #1154 · TanStack/tanstack.com · GitHub

What changed

Canonicalize every valid versioned library landing page to /{library}/latest.
Align og:url and twitter:url with the same /latest landing URL.
Keep current, historical, and prerelease landing pages renderable so the version switcher continues to work.
Leave nested documentation and non-version routes such as /charts/catalog on their existing path-aware canonical behavior.
Build the pre-existing unversioned alias redirect with a direct /{library}/latest href.
Point public library navigation destinations directly at /{library}/latest, including the header menu, “Browse the Stack,” widgets, and other shared-library consumers.
Build landing-page Home tabs with their concrete /{library}/{version} path instead of to=".." from the generic docs route.
Add regression coverage for canonical resolution, landing-tab link construction, and canonical public-library destinations.

Why

Library landing pages previously self-canonicalized from the requested pathname even though /latest is the preferred indexing URL.

TanStack Router also has both generic library landing routes and product-specific landing routes, for example:

/_library/$libraryId/$version/
/_library/table/$version/

This exposed two client-side problems:

The responsive docs navigation generated its relative Home tabs through the generic docs route. Rendering Table therefore generated /table/latest through the wrong route template and emitted the repeated route-mismatch warning from both desktop and mobile navigation trees.
Shared navigation data pointed internal links at unversioned aliases such as /table. Because these links use intent preloading, merely hovering them executed the alias redirect inside a preload and could stall the client.

Home tabs now use the concrete current landing path with no generic from or params. Public internal navigation links now skip the alias route and preload /{library}/latest directly. Relative documentation tabs retain their existing generic docs-route context.

Scope clarification

This PR intentionally does not redirect versioned landing routes. Current numbered and historical landing pages continue returning 200 so users can switch versions on landing pages without a redirect loop.

Unversioned aliases such as /table remain supported for bookmarks, typed URLs, and external links. They retain their pre-existing temporary server redirect to /latest; only internal links stop preloading those aliases. Sitemap behavior is unchanged.

Impact

Search and social crawlers receive one preferred landing URL per library, while users retain direct access to every supported landing-page version. Hovering public library links no longer preloads a redirect route, and loading Table no longer emits the ambiguous-route warning or associated dev-mode stall.

Verification

pnpm test — 142 passed, 1 expected opt-in smoke test skipped
pnpm run build
pnpm run test:tsc
pnpm run test:lint
Fresh Home inspection confirms both the header Table link and “Browse the Stack” Table card render /table/latest, with no public unversioned library aliases in either menu
Cold browser load of /table follows exactly one redirect to /table/latest, returns a complete hydrated page, and leaves the router idle
/table returns one 307 with Location: /table/latest; /table/latest returns 200
Fresh browser navigation through Home → Libraries → Table lands on /table/latest, closes the picker, and records zero route warnings
Built-server smoke checks confirmed versioned landing pages return 200 with exactly one canonical pointing to /{library}/latest, while non-landing routes retain their own canonical

Closes #1150

📝 Walkthrough

Walkthrough

Library landing routes now redirect to /{libraryId}/latest. Library navigation targets and SEO canonicalization use latest landing paths. Tests cover landing, documentation, and non-landing routes.

Changes

Library landing navigation and SEO

Layer / File(s)	Summary
Landing routes and library targets src/routes/_library/$libraryId/index.tsx, src/libraries/libraries.ts, src/components/LibrariesWidget.tsx, tests/libraries-utils.test.ts	Landing redirects and public library links now target /{libraryId}/latest. Tests verify canonical latest paths for public libraries.
Documentation tab navigation src/components/library-layout-navigation.ts, src/components/LibraryLayout.tsx, tests/charts-sidebar-navigation.test.ts	A shared helper now builds home, charts, and documentation tab link options for mobile and desktop navigation. Tests cover landing and relative documentation targets.
SEO canonicalization and coverage src/utils/seo.ts, tests/seo.test.ts	Library landing paths resolve to latest canonical URLs. Non-landing paths retain their existing canonical paths. Tests cover both behaviors.

Add integration coverage for redirects and social metadata.

These tests call only getCanonicalPath. They do not verify that unversioned aliases redirect to /{library}/latest, versioned landing pages still return 200, or seo() emits the same /latest value in canonical, og:url, and twitter:url.

Add route-level assertions and seo() metadata assertions for one current, one historical, and one prerelease landing path. This coverage gap is measured against the PR objectives.
