# useLoaderData()

> 

Use `useLoaderData()` to read the loader result for the current matched route node.

```ts
const data = useLoaderData()
```

## Returns

`ComputedRef<T | null>`

By default, `T` uses Horn's generated current-route loader data baseline.

## Related APIs

- `useLoaderError()` for the current node's loader error
- `useRouteLoaderData(routeId)` for an explicit route id

## `useRouteLoaderData(routeId)`

Use this when you want exact typing for a specific route:

```ts
const blogLayoutData = useRouteLoaderData('blog/layout')
const postData = useRouteLoaderData('blog/[slug]/page')
```

If you omit the `routeId`, Horn resolves the parent route id relative to the current matched node.

## Typing behavior

`useRouteLoaderData(routeId)` is the most precise version because the route id is part of the generated type registry.
