# Svelte Virtual

The `@tanstack/svelte-virtual` adapter is a wrapper around the core virtual logic.

## `createVirtualizer`

```tsx
function createVirtualizer<TScrollElement, TItemElement = unknown>(
  options: PartialKeys<
    VirtualizerOptions<TScrollElement, TItemElement>,
    'observeElementRect' | 'observeElementOffset' | 'scrollToFn'
  >,
): Virtualizer<TScrollElement, TItemElement>
```

This function returns a standard `Virtualizer` instance configured to work with an HTML element as the scrollElement.

## `createWindowVirtualizer`

```tsx
function createWindowVirtualizer<TItemElement = unknown>(
  options: PartialKeys<
    VirtualizerOptions<Window, TItemElement>,
    | 'getScrollElement'
    | 'observeElementRect'
    | 'observeElementOffset'
    | 'scrollToFn'
  >,
): Virtualizer<Window, TItemElement>
```

This function returns a window-based `Virtualizer` instance configured to work with the window as the scrollElement.
