Static Route Data

When creating routes, you can optionally specify a staticData property in the route's options. This object can literally contain anything you want as long as it's synchronously available when you create your route.

In addition to being able to access this data from the route itself, you can also access it from any match under the match.staticData property.

Example

src/routes/posts.tsx

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

export const Route = createFileRoute('/posts')({
  staticData: {
    customData: 'Hello!',
  },
})

You can then access this data anywhere you have access to your routes, including matches that can be mapped back to their routes.

src/routes/__root.tsx

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

export const Route = createRootRoute({
  component: () => {
    const matches = useMatches()

    return (
      <div>
        {matches.map((match) => {
          return <div key={match.id}>{match.staticData.customData}</div>
        })}
      </div>
    )
  },
})

Enforcing Static Data

If you want to enforce that a route has static data, you can use declaration merging to add a type to the route's static option:

tsx

declare module '@tanstack/react-router' {
  interface StaticDataRouteOption {
    customData: string
  }
}

Now, if you try to create a route without the customData property, you'll get a type error:

tsx

export const Route = createFileRoute('/posts')({
  staticData: {
    // Property 'customData' is missing in type '{ customData: number; }' but required in type 'StaticDataRouteOption'.ts(2741)
  },
})

Optional Static Data

If you want to make static data optional, simply add a ? to the property:

tsx

declare module '@tanstack/react-router' {
  interface StaticDataRouteOption {
    customData?: string
  }
}

As long as there are any required properties on the StaticDataRouteOption, you'll be required to pass in an object.

Common Patterns

Controlling Layout Visibility

Use staticData to control which routes show or hide layout elements:

src/routes/admin/route.tsx

export const Route = createFileRoute('/admin')({
  staticData: { showNavbar: false },
  component: AdminLayout,
})

tsx

// routes/__root.tsx
function RootComponent() {
  const showNavbar = useMatches({
    select: (matches) =>
      !matches.some((m) => m.staticData?.showNavbar === false),
  })

  return showNavbar ? (
    <Navbar>
      <Outlet />
    </Navbar>
  ) : (
    <Outlet />
  )
}

Route Titles for Breadcrumbs

src/routes/posts/$postId.tsx

export const Route = createFileRoute('/posts/$postId')({
  staticData: {
    getTitle: () => 'Post Details',
  },
})

src/components/Breadcrumbs.tsx

function Breadcrumbs() {
  const matches = useMatches()

  return (
    <nav>
      {matches
        .filter((m) => m.staticData?.getTitle)
        .map((m) => (
          <span key={m.id}>{m.staticData.getTitle()}</span>
        ))}
    </nav>
  )
}

When to Use staticData vs Context

staticData	context
Synchronous, defined at route creation	Can be async (via beforeLoad)
Available before loading starts	Can depend on params/search
Same for all instances of a route	Passed down to child routes

Use staticData for static route metadata. Use context for dynamic data or auth state that varies per request.
