React Hooks

Type-safe React hooks for accessing router state, route data, and navigation.

useRouter

Access the router instance.

import { useRouter } from '@tanstack/react-router'

function MyComponent() {
  const router = useRouter()
  
  const handleInvalidate = () => {
    router.invalidate()
  }
  
  return <button onClick={handleInvalidate}>Refresh Data</button>
}

Router Methods

const router = useRouter()

// Navigate
await router.navigate({ to: '/posts' })

// Invalidate and refetch
await router.invalidate()

// Build location
const location = router.buildLocation({ to: '/posts' })

// Match route
const match = router.matchRoute({ to: '/posts' })

// Preload route
await router.preloadRoute({ to: '/posts/$postId', params: { postId: '123' } })

useRouterState

Access and subscribe to router state.

import { useRouterState } from '@tanstack/react-router'

function NavigationStatus() {
  const isLoading = useRouterState({ select: (s) => s.isLoading })
  const location = useRouterState({ select: (s) => s.location })
  
  return (
    <div>
      {isLoading && <LoadingBar />}
      <p>Current path: {location.pathname}</p>
    </div>
  )
}
