@primer/react/dist/hooks/useProvidedRefOrCreate.d.ts

An implementation of GitHub's Primer Design System using React

import React from 'react';
/**
 * There are some situations where we only want to create a new ref if one is not provided to a component
 * or hook as a prop. However, due to the `rules-of-hooks`, we cannot conditionally make a call to `React.useRef`
 * only in the situations where the ref is not provided as a prop.
 * This hook aims to encapsulate that logic, so the consumer doesn't need to be concerned with violating `rules-of-hooks`.
 * @param providedRef The ref to use - if undefined, will use the ref from a call to React.useRef
 * @type TRef The type of the RefObject which should be created.
 *
 * @deprecated This hook is incompatible with forwarded callback refs. Prefer `useMergedRefs` with an internally
 * created ref instead.
 *
 * ```diff
 * - const ref = useProvidedRefOrCreate(forwardedRef as RefObject<...>)
 * + const ref = useRef(null)
 * + const mergedRef = useMergedRefs(forwardedRef, ref)
 *
 * - return <div ref={ref} />
 * + return <div ref={mergedRef} />
 * ```
