Functions

function chain

chain: (...callbacks: any[]) => (...args: any[]) => void;

Calls all functions in the order they were chained with the same arguments.

function createShadowTreeWalker

createShadowTreeWalker: (
    doc: Document,
    root: Node,
    whatToShow?: number,
    filter?: NodeFilter | null
) => TreeWalker;

ShadowDOM safe version of document.createTreeWalker.

function filterDOMProps

filterDOMProps: (
    props: DOMProps & AriaLabelingProps & LinkDOMProps,
    opts?: Options
) => DOMProps & AriaLabelingProps;

Filters out all props that aren't valid DOM props or defined via override prop obj.
Parameter props
The component props to be filtered.
Parameter opts
Props to override.

function focusWithoutScrolling

focusWithoutScrolling: (element: FocusableElement) => void;

function getActiveElement

getActiveElement: (doc?: Document) => Element | null;

ShadowDOM safe version of document.activeElement.

function getEventTarget

getEventTarget: <T extends Event>(event: T) => Element;

ShadowDOM safe version of event.target.

function getOffset

getOffset: (
    element: HTMLElement,
    reverse?: boolean,
    orientation?: Orientation
) => number;

function getOwnerDocument

getOwnerDocument: (el: Element | null | undefined) => Document;

function getOwnerWindow

getOwnerWindow: (
    el: (Window & typeof global) | Element | null | undefined
) => Window & typeof global;

function getScrollParent

getScrollParent: (node: Element, checkForOverflow?: boolean) => Element;

function getScrollParents

getScrollParents: (node: Element, checkForOverflow?: boolean) => Element[];

function inertValue

inertValue: (value?: boolean) => string | boolean | undefined;

function isFocusable

isFocusable: (element: Element) => boolean;

function isScrollable

isScrollable: (node: Element | null, checkForOverflow?: boolean) => boolean;

function isShadowRoot

isShadowRoot: (node: Node | null) => node is ShadowRoot;

Type guard that checks if a node is a ShadowRoot. Uses nodeType and host property checks to distinguish ShadowRoot from other DocumentFragments.

function isTabbable

isTabbable: (element: Element) => boolean;

function isVirtualClick

isVirtualClick: (event: MouseEvent | PointerEvent) => boolean;

function isVirtualPointerEvent

isVirtualPointerEvent: (event: PointerEvent) => boolean;

function mergeIds

mergeIds: (idA: string, idB: string) => string;

Merges two ids. Different ids will trigger a side-effect and re-render components hooked up with useId.

function mergeProps

mergeProps: <T extends Props[]>(
    ...args: T
) => UnionToIntersection<TupleTypes<T>>;

Merges multiple props objects together. Event handlers are chained, classNames are combined, and ids are deduplicated - different ids will trigger a side-effect and re-render components hooked up with useId. For all other props, the last prop object overrides all previous ones.
Parameter args
Multiple sets of props to merge together.

function mergeRefs

mergeRefs: <T>(
    ...refs: Array<ForwardedRef<T> | MutableRefObject<T> | null | undefined>
) => ForwardedRef<T>;

Merges multiple refs into one. Works with either callback or object refs.

function nodeContains

nodeContains: (
    node: Node | null | undefined,
    otherNode: Node | null | undefined
) => boolean;

ShadowDOM safe version of Node.contains.

function runAfterTransition

runAfterTransition: (fn: () => void) => void;

function scrollIntoView

scrollIntoView: (scrollView: HTMLElement, element: HTMLElement) => void;

Scrolls scrollView so that element is visible. Similar to element.scrollIntoView({block: 'nearest'}) (not supported in Edge), but doesn't affect parents above scrollView.

function scrollIntoViewport

scrollIntoViewport: (
    targetElement: Element | null,
    opts?: ScrollIntoViewportOpts
) => void;

Scrolls the targetElement so it is visible in the viewport. Accepts an optional opts.containingElement that will be centered in the viewport prior to scrolling the targetElement into view. If scrolling is prevented on the body (e.g. targetElement is in a popover), this will only scroll the scroll parents of the targetElement up to but not including the body itself.

function useDeepMemo

useDeepMemo: <T>(value: T, isEqual: (a: T, b: T) => boolean) => T;

function useDescription

useDescription: (description?: string) => AriaLabelingProps;

function useDrag1D

useDrag1D: (props: UseDrag1DProps) => HTMLAttributes<HTMLElement>;

function useEffectEvent

useEffectEvent: <T extends Function>(fn?: T) => T;

function useEnterAnimation

useEnterAnimation: (ref: RefObject<HTMLElement>, isReady?: boolean) => boolean;

function useEvent

useEvent: <K extends keyof GlobalEventHandlersEventMap>(
    ref: RefObject<EventTarget>,
    event: K | (string & {}),
    handler?: (this: Document, ev: GlobalEventHandlersEventMap[K]) => any,
    options?: boolean | AddEventListenerOptions
) => void;

function useExitAnimation

useExitAnimation: (ref: RefObject<HTMLElement>, isOpen: boolean) => boolean;

function useFormReset

useFormReset: <T>(
    ref:
        | RefObject<
              HTMLInputElement | HTMLTextAreaElement | HTMLSelectElement | null
          >
        | undefined,
    initialValue: T,
    onReset: (value: T) => void
) => void;

function useGlobalListeners

useGlobalListeners: () => GlobalListeners;

function useId

useId: (defaultId?: string) => string;

If a default is not provided, generate an id.
Parameter defaultId
Default component id.

function useLabels

useLabels: (
    props: DOMProps & AriaLabelingProps,
    defaultLabel?: string
) => DOMProps & AriaLabelingProps;

Merges aria-label and aria-labelledby into aria-labelledby when both exist.
Parameter props
Aria label props.
Parameter defaultLabel
Default value for aria-label when not present.

function useLoadMore

useLoadMore: (props: LoadMoreProps, ref: RefObject<HTMLElement>) => void;

function useObjectRef

useObjectRef: <T>(forwardedRef?: any) => MutableRefObject<T>;

Offers an object ref for a given callback ref or an object ref. Especially helfpul when passing forwarded refs (created using React.forwardRef) to React Aria hooks.
Parameter forwardedRef
The original ref intended to be used.
Returns
An object ref that updates the given ref.

function useResizeObserver

useResizeObserver: <T extends Element>(
    options: useResizeObserverOptionsType<T>
) => void;

function useSlotId

useSlotId: (depArray?: ReadonlyArray<any>) => string;

Used to generate an id, and after render, check if that id is rendered so we know if we can use it in places such as labelledby.
Parameter depArray
When to recalculate if the id is in the DOM.

function useSyncRef

useSyncRef: <T>(context?: ContextValue<T> | null, ref?: RefObject<T>) => void;

function useUpdateEffect

useUpdateEffect: (effect: EffectCallback, dependencies: any[]) => void;

function useUpdateLayoutEffect

useUpdateLayoutEffect: (effect: EffectCallback, dependencies: any[]) => void;

function useValueEffect

useValueEffect: <S>(
    defaultValue: S | (() => S)
) => [S, Dispatch<SetValueAction<S>>];

function useViewportSize

useViewportSize: () => ViewportSize;
