API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

• BREAKING: NotFoundRoute & notFoundRoute — v1.x deprecated the NotFoundRoute API and the routerOptions.notFoundRoute property. Use notFoundComponent in route options or defaultNotFoundComponent in createRouter instead source

• BREAKING: opts.navigate — opts.navigate inside beforeLoad and loader is deprecated since v1.x. Use throw redirect({ to: '...' }) for navigation-triggered redirects instead source

• DEPRECATED: parseParams & stringifyParams — these top-level route properties are deprecated in favor of nested params.parse and params.stringify objects for better organization source

• DEPRECATED: preSearchFilters & postSearchFilters — deprecated since v1.x in favor of the more powerful search.middlewares array for transforming search parameters source

• DEPRECATED: <ScrollRestoration /> — the component is deprecated. Use the useScrollRestoration hook or the defaultHashScrollIntoView router option for automatic hash scrolling source

• NEW: protocolAllowlist — new createRouter option to prevent XSS by restricting allowed URL protocols in links and redirects (defaults to safe web protocols) source

• NEW: SSR Methods — head, headers, and scripts methods added to route options for server-side SEO metadata, script injection, and custom HTTP headers source

• NEW: search.middlewares — new array-based middleware system supporting retainSearchParams and stripSearchParams helpers to manage query params in generated links source

• NEW: Validation Adapters — @tanstack/zod-adapter, @tanstack/valibot-adapter, and @tanstack/arktype-adapter provide type-safe validation with distinct input/output type inference source

• NEW: defaultViewTransition — added to createRouter to enable native View Transitions API support during navigation where supported by the browser source

• NEW: rewrite — createRouter option for bidirectional URL transformation, allowing patterns like stripping locale prefixes before matching and adding them back in links source

• NEW: Wrap & InnerWrap — new createRouter properties for injecting global providers (e.g., Theme, Auth) that wrap the entire router or its inner content source

• NEW: codeSplitGroupings — provides fine-grained control over how the router groups lazy-loaded route assets (loader, component, etc.) into chunks source

• DEPRECATED: Router Classes — Router, Route, RootRoute, and FileRoute classes are deprecated in favor of factory functions like createRouter, createRoute, and createFileRoute source

Also changed: rootRouteWithContext renamed to createRootRouteWithContext · defaultRemountDeps new · defaultStructuralSharing new · NotFoundError.global deprecated · search.strict new · SearchSchemaInput new tag · standard-schema support new

Best Practices

• Use getRouteApi(routeId) for type-safe hook access in child components to avoid circular dependencies with route definitions source

• Follow the specific property order (e.g., beforeLoad before loader) in createFileRoute to ensure correct TypeScript inference for context and other properties source

• Throw redirect() from beforeLoad for authentication to stop the loading lifecycle before any child route or loader executes source

• Use zodValidator with the fallback() generic from @tanstack/zod-adapter to provide defaults for invalid search params, keeping Link search props optional and type-safe source

• Configure retainSearchParams middleware in the root route to automatically persist global URL state (like themes or sessions) across all generated links source

• Include only necessary search params in loaderDeps to prevent unrelated URL changes from triggering redundant loader executions source

• Pass the abortController.signal from loader context to async fetch calls to automatically cancel stale requests when users navigate away source

• Return promises directly from loaders for deferred data loading—manual wrapping with defer() is no longer required as promises are handled automatically source

• Set defaultPreload: 'intent' in createRouter to enable global hover/touch-based preloading, which significantly improves perceived performance for most applications source

• Enable defaultStructuralSharing: true in createRouter to preserve object references in search param selectors and minimize unnecessary Vue component re-renders source
