Latest version: v1.170.18 (verified 2026-08-03)
Problem: Build fails with @tanstack/router-devtools-core not found.
Solution:
Problem: Routes not auto-generated.
Solution: TanStackRouterVite MUST come before react():
Problem: Link to not typed.
Solution:
Problem: Loader function not called on navigation.
Solution: Ensure route exports Route:
Problem: Production crashes when using TanStack Form + Router.
Solution: This is a known issue (#5734). Workaround: Use React Hook Form instead, or wait for fix.
