The ActiveLinkOptions type extends the LinkOptions type and contains additional options that can be used to describe how a link should be styled when it is active.
type ActiveLinkOptions = LinkOptions & {
activeProps?:
| React.AnchorHTMLAttributes<HTMLAnchorElement>
| (() => React.AnchorHTMLAttributes<HTMLAnchorElement>)
inactiveProps?:
| React.AnchorHTMLAttributes<HTMLAnchorElement>
| (() => React.AnchorHTMLAttributes<HTMLAnchorElement>)
}
The ActiveLinkOptions object accepts/contains the following properties:
activePropsReact.AnchorHTMLAttributes<HTMLAnchorElement>inactivePropsReact.AnchorHTMLAttributes<HTMLAnchorElement>The AsyncRouteComponent type is used to describe a code-split route component that can be preloaded using a component.preload() method.
type AsyncRouteComponent<TProps> = SyncRouteComponent<TProps> & {
preload?: () => Promise<void>
}
[!CAUTION] This class has been deprecated and will be removed in the next major version of TanStack Router. Please use the
createFileRoutefunction instead.
The FileRoute class is a factory that can be used to create a file-based route instance. This route instance can then be used to automatically generate a route tree with the tsr generate and tsr watch commands.
FileRoute constructorThe FileRoute constructor accepts a single argument: the path of the file that the route will be generated for.
string literaltsr generate and tsr watch commands.FileRoute class that can be used to create a route.FileRoute methodsThe FileRoute class implements the following method(s):

⚠️ Note: For
tsr generateandtsr watchto work properly, the file route instance must be exported from the file using theRouteidentifier.
import { FileRoute } from '@tanstack/react-router'
export const Route = new FileRoute('/').createRoute({
loader: () => {
return 'Hello World'
},
component: IndexComponent,
})
function IndexComponent() {
const data = Route.useLoaderData()
return <div>{data}</div>
}
The LinkOptions type extends the NavigateOptions type and contains additional options that can be used by TanStack Router when handling actual anchor element attributes.
type LinkOptions = NavigateOptions & {
target?: HTMLAnchorElement['target']
activeOptions?: ActiveOptions
preload?: false | 'intent'
preloadDelay?: number
disabled?: boolean
}
The LinkOptions object accepts/contains the following properties:

interface MatchRouteOptions {
pending?: boolean
caseSensitive?: boolean /* @deprecated */
includeSearch?: boolean
fuzzy?: boolean
}
The MatchRouteOptions type has the following properties:
pending propertybooleantrue, will match against pending location instead of the current locationcaseSensitivebooleantrue, will match against the current location with case sensitivitycaseSensitive option on the routerincludeSearch propertybooleantrue, will match against the current location's search params using a deep inclusive check. e.g. { a: 1 } will match for a current location of { a: 1, b: 2 }fuzzy propertybooleantrue, will match against the current location using a fuzzy match. e.g. /posts will match for a current location of /posts/123The NavigateOptions type is used to describe the options that can be used when describing a navigation action in TanStack Router.
type NavigateOptions = ToOptions & {
replace?: boolean
resetScroll?: boolean
hashScrollIntoView?: boolean | ScrollIntoViewOptions
viewTransition?: boolean | ViewTransitionOptions
ignoreBlocker?: boolean
reloadDocument?: boolean
href?: string
}
The NavigateOptions object accepts the following properties:
replacebooleanfalse.true, the location will be committed to the browser history using history.replace instead of history.push.resetScrollbooleantrue so that the scroll position will be reset to 0,0 after the location is committed to the browser history.false, the scroll position will not be reset to 0,0 after the location is committed to history.hashScrollIntoViewboolean | ScrollIntoViewOptionstrue so the element with an id matching the hash will be scrolled into view after the location is committed to history.false, the element with an id matching the hash will not be scrolled into view after the location is committed to history.scrollIntoView method as options.ScrollIntoViewOptions.viewTransitionboolean | ViewTransitionOptionsfalse.true, navigation will be called using document.startViewTransition().ViewTransitionOptions, route navigations will be called using document.startViewTransition({update, types}) where types will determine the strings array passed with ViewTransitionOptions["types"]. If the browser does not support viewTransition types, the navigation will fall back to normal document.startTransition(), same as if true was passed.ignoreBlockerbooleanfalse.true, navigation will ignore any blockers that might prevent it.reloadDocumentbooleanfalse.true, navigation to a route inside of router will trigger a full page load instead of the traditional SPA navigation.hrefType: string
Optional
This can be used instead of to to navigate to a fully built href, e.g. pointing to an external target.
The NotFoundError type is used to represent a not-found error in TanStack Router.
export type NotFoundError = {
global?: boolean
data?: any
throw?: boolean
routeId?: string
headers?: HeadersInit
}
The NotFoundError object accepts/contains the following properties:
global property (⚠️ deprecated, use routeId: rootRouteId instead)booleandefault: falsenotFoundComponent of the root route instead of bubbling up from the route that threw it. This has the same behavior as importing the root route and calling RootRoute.notFound().data propertyanynotFoundComponent when the not-found error is handledthrow propertybooleandefault: falsethrowing in a function might cause it to have a return type of never. In that case, you can use notFound({ throw: true }) to throw the not-found object instead of returning it.routeId propertystringnotFoundComponent, the error will bubble up to the parent route (and be handled by the root route if necessary). By default, TanStack Router will attempt to handle the not-found error with the route that threw it.headers propertyHeadersInit[!CAUTION] This class has been deprecated and will be removed in the next major version of TanStack Router. Please use the
notFoundComponentroute option that is present during route configuration. See the Not Found Errors guide for more information.
The NotFoundRoute class extends the Route class and can be used to create a not found route instance. A not found route instance can be passed to the routerOptions.notFoundRoute option to configure a default not-found/404 route for every branch of the route tree.
The NotFoundRoute constructor accepts an object as its only argument.
Omit<
RouteOptions,
| 'path'
| 'id'

import { NotFoundRoute, createRouter } from '@tanstack/react-router'
import { Route as rootRoute } from './routes/__root'
import { routeTree } from './routeTree.gen'
const notFoundRoute = new NotFoundRoute({
getParentRoute: () => rootRoute,
component: () => <div>Not found!!!</div>,
})
const router = createRouter({
routeTree,
notFoundRoute,
})
// ... other code
The ParsedHistoryState type represents a parsed state object. Additionally to HistoryState, it contains the index and the unique key of the route.
export type ParsedHistoryState = HistoryState & {
key?: string // TODO: Remove in v2 - use __TSR_key instead
__TSR_key?: string
__TSR_index: number
}
The ParsedLocation type represents a parsed location in TanStack Router. It contains a lot of useful information about the current location, including the pathname, search params, hash, location state, and route masking information.
interface ParsedLocation {
href: string
pathname: string
search: TFullSearchSchema
searchStr: string
state: ParsedHistoryState
hash: string
maskedLocation?: ParsedLocation
unmaskOnReload?: boolean
}
The Redirect type is used to represent a redirect action in TanStack Router.
export type Redirect = {
statusCode?: number
throw?: any
headers?: HeadersInit
} & NavigateOptions
The Redirect object accepts/contains the following properties:
statusCode propertynumberthrow propertyanythrowing in a function might cause it to have a return type of never. In that case, you can use redirect({ throw: true }) to throw the redirect object instead of returning it.headers propertyHeadersInitSince Redirect extends NavigateOptions, it also supports navigation properties:
to: Use for internal application routes (e.g., /dashboard, ../profile)href: Use for external URLs (e.g., https://example.com, https://authprovider.com)Important: For external URLs, always use the
hrefproperty instead ofto. Thetoproperty is designed for internal navigation within your application.
This type is used to register a route tree with a router instance. Doing so unlocks the full type safety of TanStack Router, including top-level exports from the @tanstack/react-router package.
export type Register = {
// router: [Your router type here]
}
To register a route tree with a router instance, use declaration merging to add the type of your router instance to the Register interface under the router property:
const router = createRouter({
// ...
})
declare module '@tanstack/react-router' {
interface Register {
router: typeof router
}
}
[!CAUTION] This class has been deprecated and will be removed in the next major version of TanStack Router. Please use the

routeTree propertyAnyRoutehistory propertyRouterHistorycreateBrowserHistory instance will be created and used.stringifySearch method(search: Record<string, any>) => stringdefaultStringifySearch.parseSearch method(search: string) => Record<string, any>defaultParseSearch.search.strict propertybooleanfalsevalidateSearch) are treated.false, unknown search params will be kept.true, unknown search params will be removed.defaultPreload propertyundefined | false | 'intent' | 'viewport' | 'render'falsefalse, routes will not be preloaded by default in any way.'intent', routes will be preloaded by default when the user hovers over a link or a touchstart event is detected on a <Link>.'viewport', routes will be preloaded by default when they are within the viewport of the browser.'render', routes will be preloaded by default as soon as they are rendered in the DOM.defaultPreloadDelay propertynumber50defaultComponent propertyRouteComponentOutletcomponent a route should use if no component is provided.defaultErrorComponent propertyRouteComponentErrorComponenterrorComponent a route should use if no error component is provided.defaultNotFoundComponent propertyNotFoundRouteComponentNotFoundnotFoundComponent a route should use if no notFound component is provided.defaultPendingComponent propertyRouteComponentpendingComponent a route should use if no pending component is provided.defaultPendingMs propertynumber1000pendingMs a route should use if no pendingMs is provided.defaultPendingMinMs propertynumber500pendingMinMs a route should use if no pendingMinMs is provided.defaultStaleTime propertynumber0staleTime a route should use if no staleTime is provided.defaultStaleReloadMode property'background' | 'blocking''background''background' preserves stale-while-revalidate behavior.'blocking' waits for the stale loader reload to finish before navigation resolves.defaultPreloadStaleTime propertynumber30_000 ms (30 seconds)preloadStaleTime a route should use if no preloadStaleTime is provided.defaultPreloadGcTime propertynumberrouterOptions.defaultGcTime, which defaults to 30 minutes.preloadGcTime a route should use if no preloadGcTime is provided.defaultGcTime propertynumbergcTime a route should use if no gcTime is provided.defaultOnCatch property(error: Error, errorInfo: ErrorInfo) => voidonCatch handler for errors caught by the Router ErrorBoundarydisableGlobalCatchBoundary propertybooleanfalsetrue, disables the global catch boundary that normally wraps all route matches. This allows unhandled errors to bubble up to top-level error handlers in the browser.protocolAllowlist propertyArray<string>DEFAULT_PROTOCOL_ALLOWLIST which includes:
http:, https:mailto:, tel:<Link to="...">navigate({ to: ... }) and navigate({ href: ... })redirect({ to: ... }) and redirect({ href: ... })URL.protocol format (lowercase with a trailing :), for example blob: or data:. If you configure protocolAllowlist: ['blob'] (without :), links using blob: will still be blocked.Example
import {
createRouter,
DEFAULT_PROTOCOL_ALLOWLIST,
} from '@tanstack/react-router'
// Use a custom allowlist (replaces the default)
const router = createRouter({
routeTree,
protocolAllowlist: ['https:', 'mailto:'],
})
// Or extend the default allowlist
const router = createRouter({
routeTree,
protocolAllowlist: [...DEFAULT_PROTOCOL_ALLOWLIST, 'ftp:'],
})
defaultViewTransition propertyboolean | ViewTransitionOptionstrue, route navigations will be called using document.startViewTransition().ViewTransitionOptions, route navigations will be called using document.startViewTransition({update, types})
where types will be the strings array passed with ViewTransitionOptions["types"]. If the browser does not support viewTransition types,
the navigation will fall back to normal document.startTransition(), same as if true was passed.defaultHashScrollIntoView propertyboolean | ScrollIntoViewOptionstrue so the element with an id matching the hash will be scrolled into view after the location is committed to history.false, the element with an id matching the hash will not be scrolled into view after the location is committed to history.scrollIntoView method as options.ScrollIntoViewOptions.caseSensitive propertybooleanfalsetrue, all routes will be matched as case-sensitive.basepath propertystring/rewrite propertyLocationRewriteThe LocationRewrite type has the following shape:
type LocationRewrite = {
input?: LocationRewriteFunction
output?: LocationRewriteFunction
}
type LocationRewriteFunction = (opts: { url: URL }) => undefined | string | URL
input: Transforms the URL before the router interprets it (browser → router)output: Transforms the URL before it's written to browser history (router → browser)Example
import { createRouter } from '@tanstack/react-router'
const router = createRouter({
routeTree,
rewrite: {
input: ({ url }) => {
// Strip locale prefix: /en/about → /about
if (url.pathname.startsWith('/en')) {
url.pathname = url.pathname.replace(/^\/en/, '') || '/'
}
return url
},
output: ({ url }) => {
// Add locale prefix: /about → /en/about
url.pathname = `/en${url.pathname === '/' ? '' : url.pathname}`
return url
},
},
})
When both basepath and rewrite are configured, they are automatically composed. The basepath rewrite runs first on input (stripping the basepath) and last on output (adding it back).

}
Example:
If you want to configure to remount all route components upon params change, use:
remountDeps: ({ params }) => params
The RouterState type represents shape of the internal state of the router. The Router's internal state is useful, if you need to access certain internals of the router, such as any pending matches, is the router in its loading state, etc.
type RouterState = {
status: 'pending' | 'idle'
isLoading: boolean
isTransitioning: boolean
matches: Array<RouteMatch>
location: ParsedLocation
resolvedLocation: ParsedLocation
}
The RouterState type contains all of the properties that are available on the router state.
status property'pending' | 'idle'isLoading propertybooleantrue if the router is currently loading a route or waiting for a route to finish loading.isTransitioning propertybooleantrue if the router is currently transitioning to a new route.matches propertyArray<RouteMatch>location propertyParsedLocationresolvedLocation propertyParsedLocationThe Router type is used to describe a router instance.
Router properties and methodsAn instance of the Router has the following properties and methods:
.update method(newOptions: RouterOptions) => voidstate propertyRouterState⚠️⚠️⚠️
router.stateis always up to date, but NOT REACTIVE. If you userouter.statein a component, the component will not re-render when the router state changes. To get a reactive version of the router state, use theuseRouterStatehook.
.subscribe method(eventType: TType, fn: ListenerFn<RouterEvents[TType]>) => () => voidRouterEvent..matchRoutes method(pathname: string, locationSearch?: Record<string, any>, opts?: { throwOnError?: boolean; }) => RouteMatch[]opts.throwOnError is true, any errors that occur during the matching process will be thrown (in addition to being returned in the route match's error property)..cancelMatch method(matchId: string) => voidmatch.abortController.abort()..cancelMatches method() => voidmatch.abortController.abort() on each one..buildLocation methodBuilds a new parsed location object that can be used later to navigate to a new location.
(opts: BuildNextOptions) => ParsedLocationfrom
stringto
string | number | nullnull, the current path will be used.params
true | Updater<unknown>true, the current params will be used. If a function is provided, it will be called with the current params and the return value will be used.search
true | Updater<unknown>true, the current search params will be used. If a function is provided, it will be called with the current search params and the return value will be used.hash
true | Updater<string>true, the current hash will be used. If a function is provided, it will be called with the current hash and the return value will be used.state
true | NonNullableUpdater<ParsedHistoryState, HistoryState>true, the current state will be used. If a function is provided, it will be called with the current state and the return value will be used.mask
objectunmaskOnReload.unmaskOnReload
booleantrue, the route mask will be removed when the page is reloaded. This can be overridden on a per-navigation basis by setting mask.unmaskOnReload in NavigateOptions..commitLocation methodCommits a new location object to the browser history.
type commitLocation = (
location: ParsedLocation & {
replace?: boolean
resetScroll?: boolean
hashScrollIntoView?: boolean | ScrollIntoViewOptions
ignoreBlocker?: boolean
},
) => Promise<void>
location
ParsedLocationreplace
booleanfalse.true, the location will be committed to the browser history using history.replace instead of history.push.resetScroll
booleantrue so that the scroll position will be reset to 0,0 after the location is committed to the browser history.false, the scroll position will not be reset to 0,0 after the location is committed to history.hashScrollIntoView
boolean | ScrollIntoViewOptionstrue so the element with an id matching the hash will be scrolled into view after the location is committed to history.false, the element with an id matching the hash will not be scrolled into view after the location is committed to history.scrollIntoView method as options.ScrollIntoViewOptions.ignoreBlocker
booleanfalse.true, navigation will ignore any blockers that might prevent it..navigate methodNavigates to a new location.
type navigate = (options: NavigateOptions) => Promise<void>
.invalidate methodInvalidates route matches by forcing their beforeLoad and load functions to be called again.
(opts?: {filter?: (d: MakeRouteMatchUnion<TRouter>) => boolean, sync?: boolean, forcePending?: boolean }) => Promise<void>filter is not supplied, all matches will be invalidatedfilter is supplied, only matches for which filter returns true will be invalidated.sync is true, the promise returned by this function will only resolve once all loaders have finished.forcePending is true, the invalidated matches will be put into 'pending' state regardless whether they are in 'error' state or not.reset the router's CatchBoundary to trigger loaders again..clearCache methodRemove cached route matches.
(opts?: {filter?: (d: MakeRouteMatchUnion<TRouter>) => boolean}) => voidfilter is not supplied, all cached matches will be removedfilter is supplied, only matches for which filter returns true will be removed..load methodLoads all of the currently matched route matches and resolves when they are all loaded and ready to be rendered.
⚠️⚠️⚠️
router.load()respectsroute.staleTime: fresh matches stay fresh, but stale matches are revalidated even if their loader key did not change. If you need to forcefully reload all active matches regardless of freshness, userouter.invalidate()instead.
(opts?: {sync?: boolean}) => Promise<void>sync is true, the promise returned by this function will only resolve once all loaders have finished..preloadRoute methodPreloads all of the matches that match the provided NavigateOptions.
⚠️⚠️⚠️ Preloaded route matches are not stored long-term in the router state. They are only stored until the next attempted navigation action.
(opts?: NavigateOptions) => Promise<RouteMatch[]>opts
NavigateOptions.loadRouteChunk methodLoads the JS chunk of the route.
(route: AnyRoute) => Promise<void>.matchRoute methodMatches a pathname and search params against the router's route tree and returns a route match's params or false if no match was found.
(dest: ToOptions, matchOpts?: MatchRouteOptions) => RouteMatch['params'] | falsedest
ToOptionsmatchOpts
MatchRouteOptionsfalse if no match was found..dehydrate methodDehydrates the router's critical state into a serializable object that can be sent to the client in an initial request.
() => DehydratedRouter.hydrate methodHydrates the router's critical state from a serializable object that was sent from the server in an initial request.
(dehydrated: DehydratedRouter) => voiddehydrated
DehydratedRouterThe ToMaskOptions type includes the same destination fields as ToOptions, excluding mask, and adds options specific to route masking.
type ToMaskOptions = {
from?: ValidRoutePath | string
to?: ValidRoutePath | string
hash?: true | string | ((prev?: string) => string)
state?: true | HistoryState | ((prev: HistoryState) => HistoryState)
} & SearchParamOptions &
PathParamOptions & {
unmaskOnReload?: boolean
}
The ToOptions type contains several properties that can be used to describe a router destination, including mask for route masking.
type ToOptions = {
from?: ValidRoutePath | string
to?: ValidRoutePath | string
hash?: true | string | ((prev?: string) => string)
state?: true | HistoryState | ((prev: HistoryState) => HistoryState)
} & SearchParamOptions &
PathParamOptions &
MaskOptions
type SearchParamOptions = {
search?: true | TToSearch | ((prev: TFromSearch) => TToSearch)
}
type PathParamOptions = {
params?:
| true
| Record<string, TPathParam>
| ((prev: TFromParams) => TToParams)
}
type MaskOptions = {
mask?: ToMaskOptions<TRouter, TMaskFrom, TMaskTo>
}
The UseMatchRouteOptions type extends the ToOptions type and describes additional options available when using the useMatchRoute hook.
export type UseMatchRouteOptions = ToOptions & MatchRouteOptions
The ViewTransitionOptions type is used to define a
viewTransition type.
interface ViewTransitionOptions {
types:
| Array<string>
| ((locationChangeInfo: {
fromLocation?: ParsedLocation
toLocation: ParsedLocation
pathChanged: boolean
hrefChanged: boolean
hashChanged: boolean
}) => Array<string> | false)
}
The ViewTransitionOptions type accepts an object with a single property:
types propertyArray<string> | ((locationChangeInfo: { fromLocation?: ParsedLocation toLocation: ParsedLocation pathChanged: boolean hrefChanged: boolean hashChanged: boolean }) => (Array<string> | false))document.startViewTransition({update, types}) calllocationChangeInfo object and returns either:
document.startViewTransition({update, types}) callfalse to skip the view transitionThe Await component is a component that suspends until the provided promise is resolved or rejected.
This is only necessary for React 18.
If you are using React 19, you can use the use() hook instead.
The Await component accepts the following props:
props.promise propPromise<T>props.children prop(result: T) => React.ReactNode
