packages/components/src/ui/phone-input.css (1)
24-27: Prefer focus-visible for better accessibility/UXUsing
:focus-visibleinstead of:focusavoids showing focus styles on mouse clicks while keeping them for keyboard navigation.Apply this small tweak:
-.phone-input .PhoneInputInput:focus { +.phone-input .PhoneInputInput:focus-visible { outline: none; border-color: hsl(var(--ring)); }packages/components/src/remix-hook-form/phone-input.tsx (1)
12-23: Optional: memoize mergedcomponentsto reduce re-renders
componentsis a new object each render, which may cause unnecessary child updates. Memoize it by its inputs.- const { components: overrideComponents, ...rest } = props; - const components = { ...defaultComponents, ...overrideComponents }; + const { components: overrideComponents, ...rest } = props; + const components = React.useMemo( + () => ({ ...defaultComponents, ...overrideComponents }), + [overrideComponents], + );apps/docs/src/remix-hook-form/phone-input.test.tsx (1)
2-2: Use specific entry-point import for PhoneInputPer repo guidelines, import components from specific entry points rather than the package root.
Apply this diff:
-import { PhoneInput } from '@lambdacurry/forms'; +import { PhoneInput } from '@lambdacurry/forms/remix-hook-form/phone-input';apps/docs/src/remix-hook-form/phone-input.stories.tsx (3)
6-6: Separate type-only imports from value imports (import order guideline)Split the
react-routerimport so the type is imported as type-only, grouped separately.Apply this diff:
-import { type ActionFunctionArgs, useFetcher } from 'react-router'; +import type { ActionFunctionArgs } from 'react-router'; +import { useFetcher } from 'react-router';
198-241: Consider adding play functions for non-default stories or explicitly mark as docs-onlyGuideline states each story should exercise default, invalid, and valid phases. If
WithCustomStylingis intended as documentation-only, consider adding a minimal play that asserts render and a submit showing validation, or explicitly mark it as docs-only via a parameter.Example minimal play:
export const WithCustomStyling: Story = { decorators: [routerDecorator], /* ...existing render... */ play: async ({ canvasElement }) => { const canvas = within(canvasElement); const input = canvas.getByLabelText('Custom Styled Phone Input'); await userEvent.click(canvas.getByRole('button', { name: 'Submit' })); await expect(canvas.findByText('USA phone number is required')).resolves.toBeInTheDocument(); await userEvent.type(input, '2025550123'); await userEvent.click(canvas.getByRole('button', { name: 'Submit' })); }, };If you prefer to keep it docs-only, add:
parameters: { test: { disable: true } }
243-316: Same suggestion for country variants storyAdd a minimal play (or disable tests) to align with the “stories as tests” guideline.

Confirm test runner (Jest vs Vitest) — mocking API differs
This file uses jest.mock/jest.fn/jest.clearAllMocks. If the repo uses Vitest (common with Vite/Storybook), these should be vi.mock/vi.fn/vi.clearAllMocks. Mismatch will cause runtime errors.
Run this script to confirm the test runner and dependencies:
If Vitest is used, apply this diff:
-// Mock useFetcher
-jest.mock('react-router', () => ({
- useFetcher: jest.fn(),
-}));
-
-const mockUseFetcher = useFetcher as jest.MockedFunction<typeof useFetcher>;
+// Mock useFetcher

+const mockUseFetcher = useFetcher as unknown as jest.MockedFunction<typeof useFetcher>;And in the test lifecycle:

Switch mocks from Jest to Vitest (vi.*) in your Storybook tests
Your docs app is running tests through Storybook Test Runner (which bundles Vitest under the hood), so calls to jest.mock/jest.fn/jest.clearAllMocks will fail at runtime. Update both test files to use the Vitest API instead:
• apps/docs/src/remix-hook-form/phone-input.test.tsx
• apps/docs/src/remix-hook-form/form-error.test.tsx
Example diff:
-// Mock useFetcher
-jest.mock('react-router', () => ({
- useFetcher: jest.fn(),
-}));
-
-const mockUseFetcher = useFetcher as jest.MockedFunction<typeof useFetcher>;
+// Mock useFetcher
+vi.mock('react-router', () => ({
+ useFetcher: vi.fn(),
+}));
+
+const mockUseFetcher = useFetcher as unknown as jest.MockedFunction<typeof useFetcher>;And in your test setup:
-beforeEach(() => {
- jest.clearAllMocks();
-});
+beforeEach(() => {
+ vi.clearAllMocks();
+});No extra dependencies are needed—@storybook/test-runner already brings in Vitest’s globals.

In apps/docs/src/remix-hook-form/phone-input.test.tsx around lines 11 to 16,
tests are using Jest globals (jest.mock, jest.fn, jest.MockedFunction) but
Storybook Test Runner uses Vitest; replace jest.* calls with vi.* equivalents
(e.g., vi.mock, vi.fn) and update any typings to Vitest-compatible types (use
vi.Mock or change casting to match vi.fn) and ensure test teardown uses
vi.clearAllMocks; apply the same replacements in
apps/docs/src/remix-hook-form/form-error.test.tsx so both test files use Vitest
APIs instead of Jest.

Declare react-phone-number-input in the components package, not at the repo root
The react-phone-number-input library is consumed by code under packages/components. Keeping it only at the root relies on hoisting during development and will break consumers once @lambdacurry/forms packages are published (the dependency won’t be present in the published package). Move it to packages/components/package.json and remove it from the root.
Apply this diff to the root package.json to remove the misplaced dependency:
- "react-phone-number-input": "^3.4.12",Then, add it to packages/components/package.json (create the dependency block if it doesn’t exist):
{
"name": "@lambdacurry/components",
"version": "0.2.0",
"dependencies": {
"react-phone-number-input": "^3.4.12"
}
}Run this script to confirm no other packages import react-phone-number-input directly and to locate where it’s used:
🏁 Script executed:

Move react-phone-number-input into packages/components
To ensure the phone input dependency is packaged correctly (and avoid breaking consumers post-publish), remove it from the repo root and declare it in the components package:
• In package.json (repo root), remove:
- "react-phone-number-input": "^3.4.12",• In packages/components/package.json, add under dependencies (creating the block if needed):
{
"name": "@lambdacurry/components",

In package.json around line 28, remove the "react-phone-number-input": "^3.4.12"
dependency from the repo root and instead add it to
packages/components/package.json under the "dependencies" section (create the
dependencies block if it doesn't exist) so the phone input is packaged with the
components package and not declared at the monorepo root.

I've checked the package.json and yarn.lock files, and the react-phone-number-input dependency (version ^3.4.12) is already included in both files from our previous commits. The dependency was added when we initially created the phone input component.
Here's what I found:
- The dependency is correctly listed in package.json:
"react-phone-number-input": "^3.4.12",- I ran
yarn add react-phone-number-inputto ensure everything is up to date, and there were no changes to the yarn.lock file, confirming it was already properly updated.
Is there anything specific about the dependency that you'd like me to modify?

Fix ref handling and prevent overriding merged components/control props
Two issues:
- The component types
refas a prop, but function components don’t receiverefthat way. UseReact.forwardRef. - The spread
{...props}comes aftercomponentsandcontrol, so a user-suppliedcomponentsprop would override the merged one (andcontrolis supposed to be omitted). Pass...restfirst, then explicitly setcontroland the mergedcomponents.
Apply this refactor:

In packages/components/src/remix-hook-form/phone-input.tsx around lines 9 to 26,
the component incorrectly types and handles ref and allows props to override
merged control/components; convert the component to use
React.forwardRef<HTMLInputElement, PhoneInputProps> so ref is forwarded
properly, destructure props into { components: userComponents, ...rest } (omit
control from rest so it can't be overridden), build mergedComponents = {
FormControl, FormLabel, FormDescription, FormMessage, ...userComponents }, then
render <BasePhoneInputField {...rest} control={control}
components={mergedComponents} ref={ref} /> (ensure rest is spread first so you
explicitly set control and components afterwards), and set
PhoneInput.displayName after the forwardRef call to preserve the name.

@coderabbitai we're using react 19 so ref as a prop should be good!

🧩 Analysis chain
@jaruesink You're absolutely right about React 19! Thank you for the clarification. In React 19, ref can indeed be passed as a regular prop without needing forwardRef.
However, the second part of my suggestion about prop spreading order is still relevant. The current code spreads {...props} after setting control and components, which means if a user accidentally passes these props, they could override the intended values:
// Current: user props could override control/components
return <BasePhoneInputField control={control} components={components} {...props} />;
// Better: explicit control over which props take precedence
const { components: overrideComponents, ...rest } = props;
const components = { ...defaultComponents, ...overrideComponents };
return <BasePhoneInputField {...rest} control={control} components={components} />;This ensures control from the Remix context and the properly merged components can't be accidentally overridden by user props.

Perfect! I can confirm you're using React ^19.0.0 in both the components package and docs app. You're absolutely correct about ref as a prop working in React 19.
Let me update my suggestion to only address the actual issue - the prop spreading order that could allow user props to override control and components:
-export const PhoneInput = function RemixPhoneInput(props: PhoneInputProps & { ref?: React.Ref<HTMLInputElement> }) {
+export const PhoneInput = function RemixPhoneInput(props: PhoneInputProps & { ref?: React.Ref<HTMLInputElement> }) {
const { control } = useRemixFormContext();
// Merge the provided components with the default form components
const defaultComponents = {
FormControl,
FormLabel,
FormDescription,
FormMessage,
};
- const components = {
- ...defaultComponents,
- ...props.components,
- };
+ const { components: overrideComponents, ...rest } = props;
+ const components = { ...defaultComponents, ...overrideComponents };
- return <BasePhoneInputField control={control} components={components} {...props} />;
+ return <BasePhoneInputField {...rest} control={control} components={components} />;
};This ensures that control from the Remix context and the properly merged components can't be accidentally overridden by user props, while keeping the React 19 ref handling as-is.

Prop name collision: 'className' from field vs input props
PhoneInputFieldProps extends PhoneInputProps (which already defines className) and then re-introduces className?: string. This overload conflates the field wrapper's container class and the input container class, causing one of them to be silently dropped depending on spread order.
Prefer a distinct prop for the field wrapper (e.g., rootClassName) to avoid collision with the input component’s className. Apply this diff:
-export interface PhoneInputFieldProps extends Omit<PhoneInputProps, 'value' | 'onChange'> {

🛠️ Refactor suggestion
Ref is not forwarded — use React.forwardRef and fix class handling
Currently, ref is destructured from props on a function component, which won’t receive React refs. Also, the focus ring classes are assigned to className (which maps to the input wrapper in PhoneNumberInput), while inputClassName isn’t augmented with the focus styles. This leads to styling being applied to the wrong element and breaks ref forwarding.
Apply this refactor:
-export const PhoneInputField = function PhoneInputField({
- control,
- name,
- label,
- description,
- className,
- components,
- ref,
- ...props
-}: PhoneInputFieldProps & { ref?: React.Ref<HTMLInputElement> }) {
+export const PhoneInputField = React.forwardRef<HTMLInputElement, PhoneInputFieldProps>(function PhoneInputField(
+ {
+ control,
+ name,
+ label,
+ description,
+ rootClassName,
+ components,
+ inputClassName,
+ ...props
+ },
+ ref,
+) {
// Use the custom Input component if provided, otherwise use the default PhoneNumberInput
const InputComponent = components?.Input || PhoneNumberInput;
return (
<FormField
control={control}
name={name}
render={({ field, fieldState }) => {
return (
- <FormItem className={className}>
+ <FormItem className={rootClassName}>
{label && <FormLabel Component={components?.FormLabel}>{label}</FormLabel>}
<FormControl Component={components?.FormControl}>
<InputComponent
{...field}
- {...props}
- ref={ref}
- className={cn('focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2')}
+ {...props}
+ ref={ref}
+ // Apply focus styles to the actual input element while preserving any incoming inputClassName
+ inputClassName={cn(
+ 'focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2',
+ inputClassName,
+ )}
/>
</FormControl>
{description && <FormDescription Component={components?.FormDescription}>{description}</FormDescription>}
{fieldState.error && (
<FormMessage Component={components?.FormMessage}>{fieldState.error.message}</FormMessage>
)}
</FormItem>
);
}}
/>
);
-};
+});Note: This keeps className from PhoneInputProps available for the input wrapper (handled inside PhoneNumberInput) and uses rootClassName for the field container.

React 19 ref as prop function components forwardRef changes
💡 Result:
In React 19, function components no longer require forwardRef to receive a ref: you now pass ref directly as a prop, and forwardRef is officially deprecated for function components[1][2][3][4][5][6][7].
Essential changes and context:
-
Old behavior (pre-React 19):
- To pass a
refinto a function component, you had to wrap it withforwardRef[1][3]. - The render function signature was:
import { forwardRef } from "react"; const MyInput = forwardRef(function MyInput(props, ref) { ... });
- To pass a
-
New behavior (React 19):
- You can define your component to accept
refdirectly as a prop:const MyInput = function MyInput({ ref, ...props }) { ... }
- Use it like this:
<MyInput ref={ref} />
- No wrapping with
forwardRefis needed for function components[2][4][5][6][7].
- You can define your component to accept
-
Migration: React provides a codemod to automate removal of
forwardReffor function components, transforming code to the new signature[5]. -
Why this matters:
- Cleaner code: Less boilerplate and easier maintenance.
- Better readability: No need to mentally track
forwardRefwrappers. - Natural API:
refbehaves like other props[2][4][7].
-
Limits and caveats:
- Class components: You still cannot pass refs as props to classes because refs for classes refer to the instance rather than the DOM element[4].
- Imperative use only: React still advises using refs only for imperative tasks not expressible as props (e.g., focusing an input)[1][3].
-
Callback ref cleanup: In React 19, callback refs can now return a cleanup function, simplifying resource management when components unmount[2].
Summary table:
| React Version | How to pass ref to function components | forwardRef required? |
|---|---|---|
| 18 and earlier | Must wrap with forwardRef |
Yes |
| 19+ | Use ref as a direct prop |
No (deprecated) |
Key code migration:
// Old (React 18 and earlier)
import { forwardRef } from "react";
const MyInput = forwardRef(function MyInput(props, ref) {
return <input ref={ref} {...props} />;
});
// New (React 19)
const MyInput = function MyInput({ ref, ...props }) {
return <input ref={ref} {...props} />;
};Conclusion:
For function components in React 19 and onward, use ref as a direct prop; forwardRef is deprecated. Update your codebases accordingly for simplification and future compatibility[1][2][3][4][5][6][7].

@jaruesink You're absolutely right! In React 19, ref is indeed a regular prop for function components, and forwardRef is officially deprecated for this use case. Thanks for the correction!
The current code structure is actually fine for React 19. However, there's still the styling issue I mentioned - the focus ring classes should be applied to inputClassName (which targets the actual input element) rather than className (which targets the wrapper div).
Here's the updated suggestion that keeps the React 19 ref-as-prop approach:
export const PhoneInputField = function PhoneInputField({
control,
name,
label,
description,
className,
inputClassName,
components,
ref,
...props
}: PhoneInputFieldProps & { ref?: React.Ref<HTMLInputElement> }) {
const InputComponent = components?.Input || PhoneNumberInput;
return (
<FormField
control={control}
name={name}
render={({ field, fieldState }) => {
return (
<FormItem className={className}>
{label && <FormLabel Component={components?.FormLabel}>{label}</FormLabel>}
<FormControl Component={components?.FormControl}>
<InputComponent
{...field}
{...props}
ref={ref}
// Apply focus styles to the actual input element
inputClassName={cn(
'focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2',
inputClassName,
)}
/>
</FormControl>
{description && <FormDescription Component={components?.FormDescription}>{description}</FormDescription>}
{fieldState.error && (
<FormMessage Component={components?.FormMessage}>{fieldState.error.message}</FormMessage>
)}
</FormItem>
);
}}
/>
);
};The main fix is ensuring the focus ring styles are applied via inputClassName so they reach the actual input element rather than the wrapper.

@jaruesink That's a great point! Let me examine the PhoneNumberInput component to understand how the styling architecture is set up for prefix/suffix support.

@jaruesink You're absolutely right about the intentional design! Looking at the PhoneNumberInput component, I can see the architecture is set up to support that pattern.
Currently, the PhoneNumberInput renders just a single <input> element where both className and inputClassName get merged and applied to the same element via the cn() utility. The component already includes the focus ring styles by default:
className={cn(
'flex h-10 w-full text-base sm:text-sm rounded-md border border-input bg-background px-3 py-2 ring-offset-background file:border-0 file:bg-transparent file:text-sm file:font-medium file:text-foreground placeholder:text-muted-foreground focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:cursor-not-allowed disabled:opacity-50',
inputClassName,
)}The distinction between className and inputClassName makes perfect sense for when you add prefix/suffix support later - you'd have a wrapper div that gets className (for the container/focus ring) and the actual input that gets inputClassName (for input-specific styles).
So the current PhoneInputField implementation is correct as-is! The component already handles its own focus styles, and the architecture is ready for future prefix/suffix enhancements. Thanks for clarifying the intentional design decision.

Learning: In the lambda-curry/forms components library, the distinction between className and inputClassName in form field components is intentionally designed to support future prefix/suffix functionality, where className would apply to a wrapper container and inputClassName to the actual input element.

- const formatFullNumber = React.useCallback((country: string, nationalNumber: string) => { - if (!nationalNumber) return ''; - - const formatter = new AsYouType(country); - const formatted = formatter.input(nationalNumber); - - if (international) { - return `+${getCountryCallingCode(country)}${formatted.startsWith('+') ? formatted.substring(1) : formatted}`; - } - - return formatted; - }, [international]); + const formatFullNumber = React.useCallback( + (country: string, nationalNumber: string) => { + if (!nationalNumber) return ''; + const formatter = new AsYouType(country); + formatter.input(nationalNumber); + const e164 = formatter.getNumberValue(); + if (international) { + // Prefer E.164 when available; fallback to country code + digits only + return e164 ?? `+${getCountryCallingCode(country)}${nationalNumber.replace(/\D/g, '')}`; + } + // For national mode, return the unprefixed input (unformatted) to avoid injecting spaces + return nationalNumber; + }, + [international], + );Please confirm whether your consuming validators expect E.164; if not, we can keep current behavior.

In apps/docs/src/remix-hook-form/phone-input.test.tsx around line 2, the test
imports PhoneInput from the package root which violates the repo's guideline to
import from specific entry points; change the import to the package's explicit
entry (for example import from '@lambdacurry/forms/PhoneInput' or the documented
entry path) so the test imports the component from the specific module entry to
keep bundles lean and follow project import rules.

packages/components/src/ui/phone-input.tsx lines 106-117: the component isn't
passing the consumer's forwarded ref to the underlying <input>, so external
callers can't control or focus the input; update the component to accept a
forwarded ref (wrap with React.forwardRef and add a ref parameter), and attach
it to the input element (either use the forwarded ref directly or merge it with
the internal inputRef using a small helper like useMergeRefs or a manual
assignment) so both internal logic and consumer refs point to the same input
node.

export const Default: Story = { - decorators: [ - withReactRouterStubDecorator({ - routes: [ - { - path: '/', - Component: ControlledPhoneInputExample, - action: async ({ request }: ActionFunctionArgs) => handleFormSubmission(request), - }, - ], - }), - ], + decorators: [routerDecorator],Add this helper near the top of the file (outside meta) to define the shared decorator:
// Place near the imports const routerDecorator = withReactRouterStubDecorator({ routes: [ { path: '/', Component: ControlledPhoneInputExample, action: async ({ request }: ActionFunctionArgs) => handleFormSubmission(request), }, ], });

196-255: Add a minimal play test to WithCustomStyling to meet story-as-tests guidelineGuidelines request stories include default, invalid, and valid flows. Default already covers these; for consistency and regression protection, consider adding a brief play step (e.g., submit empty, assert validation error).
Example snippet for
WithCustomStyling.play:WithCustomStyling.play = async ({ canvasElement, step }) => { const canvas = within(canvasElement); await step('Shows validation errors on empty submit', async () => { const submitButton = await canvas.findByRole('button', { name: 'Submit' }); await userEvent.click(submitButton); await expect(canvas.findByText('USA phone number is required')).resolves.toBeInTheDocument(); await expect(canvas.findByText('International phone number is required')).resolves.toBeInTheDocument(); }); };packages/components/src/ui/phone-input.tsx (1)

15-25: Prop collision: distinguish field container vs. input styling

47-61: Apply container vs. input classes to the right elements
- Use
rootClassNameonFormItem(field container).- Keep input focus styles on the input via
inputClassName. You already add a focus-within ring on the wrapper div; ensure the input doesn’t also add its own ring to avoid double visuals.- <FormItem className={className}> + <FormItem className={rootClassName}> @@ - <InputComponent + <InputComponent {...field} {...props} ref={ref} - className={cn('w-full', props.className)} - inputClassName={cn('focus-visible:ring-0 focus-visible:ring-offset-0 border-input', inputClassName)} + className={cn('w-full', props.className)} + inputClassName={cn( + 'focus-visible:ring-0 focus-visible:ring-offset-0 border-input', + inputClassName, + )} />If you adopt the

🛠️ Refactor suggestion
FormMessage should fall back to FormItemContext for IDs (fix broken aria wiring)
Right now FormMessage relies on formMessageId being passed as a prop. In typical usage (e.g., inside FormItem), we don't pass that prop, so the <p> will render with id={undefined} and won't be referenced by aria-describedby from FormControl. Use FormItemContext as the default source for the id, and still allow explicit overrides via the prop.
Apply this diff within the current function to add a context fallback and use a single resolved id:
export function FormMessage({
Component,
className,
formMessageId,
error,
children,
...rest
}: FormMessageProps) {
+ const { formMessageId: ctxFormMessageId } = React.useContext(FormItemContext);
+ const id = formMessageId ?? ctxFormMessageId;
if (Component) {
// Ensure custom props do not leak to DOM by not spreading them
- return <Component id={formMessageId} className={className} error={error} {...rest}>{children}</Component>;
+ return (
+ <Component id={id} className={className} error={error} {...rest}>
+ {children}
+ </Component>
+ );
}And update the default render path similarly:
return (
<p
- id={formMessageId}
+ id={id}
className={cn('form-message text-sm font-medium text-destructive', className)}
data-slot="form-message"
{...rest}
>
{body}
</p>
);Additionally, for consistency, consider updating FormControl and FormDescription to also consume FormItemContext by default (with props as explicit override). If helpful, I can follow up with a complete patch for those components.

In packages/components/src/ui/form.tsx around lines 138 to 149, FormMessage
currently uses the incoming prop formMessageId directly which can be undefined;
resolve an id by reading the FormItemContext (e.g. const { formMessageId:
contextId } = useContext(FormItemContext)) and then compute a single resolvedId
= formMessageId ?? contextId so the component falls back to context but still
allows explicit override; use resolvedId in both the custom Component branch
(id={resolvedId}) and the default render branch (id={resolvedId}) so aria wiring
works correctly.

🛠️ Refactor suggestion
Forward the ref and support container className
Refs won’t reach consumers because the component is a plain function and ref is typed in props. Switch to React.forwardRef and pass the ref to the input. Also, className is defined but never applied; either apply it to a wrapping container or remove it to avoid confusion. Given PhoneInputField passes className expecting container styling, apply it to a wrapper.
Apply this refactor:

aria-label={props['aria-label']}is unnecessary since{...props}already handles it.- This keeps input styling on the input and allows container styling via
className, which aligns with howPhoneInputFieldcomposes classes.

currently accepts a ref in props but is a plain function so refs won’t reach the
input and className is declared but never applied; change the component to use
React.forwardRef so it receives (props, ref) and forward that ref to the
underlying input element, apply the passed className to a wrapping container
element (keeping inputClassName on the input), remove the redundant explicit
aria-label since {...props} already spreads it, and update the component’s type
signature to forwardRef<HTMLInputElement, PhoneInputProps> so consumers can
attach refs correctly.

react 19 ref as props is supported right?

🧩 Analysis chain
@jaruesink You're absolutely right! Based on the learnings I have from our previous discussions in this PR, React 19 does support passing ref as a regular prop to function components without needing React.forwardRef.
The CodeRabbit suggestion I made was following pre-React 19 patterns. In React 19, you can indeed pass ref directly as a prop, so the current implementation in the diff is actually correct for React 19.
However, the className prop is still declared but not applied to any element, which should still be addressed. You could either:
- Apply it to a wrapper div as suggested, or
- Remove it from the props interface if it's not needed
The ref handling part of my suggestion can be ignored for React 19 compatibility.

Learning something new!
🌐 Web query:
React 19 ref as prop support without forwardRef function components
💡 Result:
Short answer
- Yes — in React 19 you can receive ref on a function component via props (no forwardRef needed). React treats ref like any other prop for function components. (react.dev, 19.react.dev)
What that looks like (JS)
- Parent:
const inputRef = React.useRef(null);
- Child:
function MyInput({ ref, ...props }) {
return <input ref={ref} {...props} />;
}
This is valid in React 19 because ref is passed into props for function components. (react.dev)
TypeScript tips
- Easiest: type the prop as React.Ref (and make it optional). Example:
type Props = { placeholder?: string; ref?: React.Ref };
function MyInput({ placeholder, ref }: Props) { return ; }
This pattern is recommended by community examples and works in practice. (stackoverflow.com) - If you’re wrapping HTML elements, you can also use React.ComponentProps<'tag'> / ComponentPropsWithRef helper types to get the right prop set (adjust depending on whether you want to include/omit refs for older React compatibility). (medium.com)
Important behavioral/caveat notes
- Class components: refs to class components are still handled the old way and are not passed into props. (react.dev)
- ref callback cleanup: ref callbacks can now return cleanup functions (React will run them on unmount). Expect small differences vs. older React (previously refs were called with null on unmount). (react.dev, 19.react.dev)
- cloneElement / element.ref: libraries that previously read element.ref (e.g., child.ref) may see warnings or behavior differences in React 19 — ref is now in element.props.ref for function components; accessing element.ref can trigger deprecation warnings in some versions. If you clone or inspect children, prefer child.props.ref or update code per migration guidance. (github.com)
- useImperativeHandle still works; you can accept a ref prop and use useImperativeHandle against it as before. (react.dev)
Migration / library author guidance
- For code that must support React <19, conditionally wrap with forwardRef when running on older React (e.g., detect React.version and wrap only when not on 19+), or publish two entrypoints / a codemod. Some libraries have suggested runtime shims for compatibility. Example approach (pseudo):
const _Comp = (props) => { /* accepts props.ref */ };
export const Comp = React.version?.startsWith('19') ? _Comp : React.forwardRef((p, ref) => _Comp({ ...p, ref }));
This pattern is used in community migrations. (github.com)
Quick checklist before removing forwardRef
- Update typings (use React.Ref or ComponentProps helpers). (stackoverflow.com, medium.com)
- Search for code that reads element.ref (instead of element.props.ref) — update to props.ref or stop reading it. (github.com)
- Ensure consumers on older React versions still work (or provide a compatibility layer / codemod).
- Test useImperativeHandle, callback ref cleanup and hydration behaviors after upgrade. (react.dev)
If you want, I can:
- Give precise TS types for a concrete component you have, or
- Produce a codemod / migration checklist for a component library (to remove forwardRef safely and keep backward compatibility).
Which of those would help you next?

@jaruesink You're absolutely correct! The web search confirms that React 19 does support ref as a regular prop for function components without needing React.forwardRef.
The current implementation in the diff is actually perfect for React 19:
export const PhoneNumberInput = ({
value,
onChange,
isInternational = false,
className,
inputClassName,
...props
}: PhoneInputProps & { ref?: React.Ref<HTMLInputElement> }) => {My CodeRabbit suggestion about using forwardRef was following pre-React 19 patterns and can be disregarded for React 19 compatibility.
The only remaining issue is that className is declared in the props but never actually applied to any element in the component. You'll want to either:
- Apply it to a wrapper div, or
- Remove it from the props interface if it's not needed
Thanks for the correction! The React 19 ref-as-prop feature is indeed a great simplification.
