TanStack Router Runtime Behavior and SSR

Use this skill when the task is primarily about what happens after a route matches: loading, failure, recovery, navigation side effects, or Router SSR.

Scope

• pending, error, and not-found boundaries
• retry and recovery behavior
• scroll restoration and navigation blocking
• document head and script emission
• Router SSR and hydration guardrails

Routing cues

• pendingComponent, errorComponent, notFoundComponent, router.invalidate(), scroll restoration, navigation blocking, head(), HeadContent, Scripts, or Router SSR -> use this skill
• route trees, params, Link, Navigate, or route masking -> use tanstack-router-route-trees-and-navigation
• validateSearch, loaderDeps, loader, beforeLoad, auth, route context, or preloading -> use tanstack-router-search-params-and-loaders
• generated route trees, plugin config, .lazy.tsx, or ESLint Router tooling -> use tanstack-router-file-based-routing-and-tooling
