# AttachmentOptions

Options for the render scope owned by a native Svelte attachment.

## Signatures

```ts
export interface AttachmentOptions<E> {
    readonly stopPropagation?: RootEventOptions;
    readonly onReady?: () => void;
    readonly onError?: (cause: Cause.Cause<E>) => void;
}
```

## Property: onReady

Runs after Typed attaches its first output; nested frameworks commit on their own schedule.
