fix(tanstack-react-start): require Start 1.168.0 for CSRF middleware by SarahSoutoul · Pull Request #10102 · clerk/javascript

SarahSoutoul · 2026-10-06T20:34:32Z

Description

Raise the minimum supported @tanstack/react-start peer version from ^1.167.17 to ^1.168.10 and @tanstack/react-router from ^1.168.10 to ^1.170.7. These versions align Clerk's supported range with TanStack Start's React Router dependency and make createCsrfMiddleware work reliably during Vite SSR for Clerk's documented setup. Includes a minor changeset.

To verify the minimum versions, install the SDK alongside Start 1.168.10 and Router 1.170.7 in a TanStack app and run a server function with the documented CSRF middleware. The related Docs PR shows the setup.

After merge

Confirm the JavaScript release workflow opens a Version Packages PR containing the @clerk/tanstack-react-start changeset; merge that release PR when ready. -> Version Packages PR
Verify the new package is published to npm and its peer dependencies require @tanstack/react-start ^1.168.10 and @tanstack/react-router ^1.170.7.

Recommended order

SDK — clerk/javascript#10102. Merge its follow-up Version Packages PR and verify the new @clerk/tanstack-react-start release before merging the Docs PR. Dashboard, Skills, and Quickstart can merge in any order.
CLI — clerk/cli#523. Merge its follow-up Version Packages PR and verify a stable clerk@latest release before the docs PR.
Dashboard — clerk/dashboard#10372.
Skills — clerk/skills#95.
Quickstart — clerk/clerk-tanstack-react-start-quickstart#16. Its existing Clerk SDK 1.6.4 lockfile entry already works with the PR's pinned Start and Router versions.
Docs — clerk/clerk#3539. Merge last, after the SDK and CLI stable releases and the other source PRs. Remove its do not merge label only when those gates are met.

Checklist

pnpm test runs as expected.
pnpm build runs as expected.

📝 Walkthrough

Walkthrough

The @clerk/tanstack-react-start package raises its peer dependency minimums to @tanstack/react-router ^1.170.7 and @tanstack/react-start ^1.168.10. The README updates its prerequisites to match. A minor changeset records these minimums and documents registering createCsrfMiddleware() for serverFn handlers before clerkMiddleware().

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Suggested reviewers: wobsoriano

Merge Risk: 🔵 Low · up to 82c22

The package and README set the new TanStack minimums, but CLI initialization can still leave some apps below them. Aligning the CLI would close this bounded compatibility gap.

Expanded the changeset to explain that a src/start.ts turns off Start's default CSRF protection, with a snippet that registers createCsrfMiddleware() before clerkMiddleware()
Updated the README prerequisites to Start ^1.168.0 and Router ^1.170.0 to match the new minimums
