useActionState and useFormStatus solve different parts of a React form: use the first when an action’s returned value should become component state, and the second when a component inside a form needs to know whether that form is submitting. You can use both together—one to display the action result and the other to update a nested submit button.
What is the difference between useActionState and useFormStatus?
| Hook | What it provides | Where to call it | Use it for |
|---|---|---|---|
useActionState |
The latest value returned by an action, a dispatcher, and an isPending flag |
At the top level of the component or custom hook that owns the action state | Showing a validation result, confirmation, updated count, or other action result |
useFormStatus |
The parent form’s pending, submitted data, method, and action |
In a child component rendered inside the form | Showing submission feedback or changing a child control while the form is pending |
The hooks are complementary, not interchangeable. useActionState tracks state returned by an action; useFormStatus reports the status and details of a parent form submission. React’s useActionState reference and useFormStatus reference document these separate roles.
How do you use both hooks in a form?
This example returns a message from the action and renders it after submission. A nested submit button reads the parent form’s pending status.
Recommended Free Tools
import { useActionState } from 'react';
import { useFormStatus } from 'react-dom';
async function saveMessage(previousState, formData) {
const message = formData.get('message');
if (!message) {
return { error: 'Enter a message before submitting.' };
}
// Perform the save operation here.
return { error: null, notice: 'Message saved.' };
}
function SubmitButton() {
const { pending } = useFormStatus();
return (
);
}
export default function MessageForm() {
const [state, formAction, isPending] = useActionState(saveMessage, {
error: null,
notice: null,
});
return (
<form action={formAction}>
<label>
Message
<input name="message" />
</label>
<SubmitButton />
{isPending && <p>Saving your message…</p>}
{state.error && <p role="alert">{state.error}</p>}
{state.notice && <p>{state.notice}</p>}
</form>
);
}In the rendered JSX, write ordinary JSX tags such as <form> directly; the escaped tags above keep the example’s form markup visible inside a code block. The isPending value comes from the action state hook, while the nested button’s pending value comes from the form it is inside. Choose one indicator or both according to what the interface needs.

How does useActionState work?
The current React reference gives the signature useActionState(action, initialState, permalink?). Call it at the top level of a component or custom hook. It returns exactly three values: the current state, a dispatcher for the action, and an isPending flag. See the official API reference for details.
The initial state is used before the action has produced a result. When the action completes, its returned value becomes the next state. When you pass the dispatcher to a form’s action prop, the form submission is handled as a Transition.
Remember the extra first argument
Wrapping an action with useActionState changes its signature: the action receives the previous state first, followed by its usual payload. For a form action, the second argument is the submitted FormData. Omitting the first parameter or treating the first one as form data can make code read the wrong value.

async function submit(previousState, formData) {
const email = formData.get('email');
return { email, message: 'Received' };
}Return expected failures; throw unexpected ones
For a known validation problem, return structured information as state and render it in the form. For an unexpected error, React’s reference describes throwing so the nearest Error Boundary can handle it. Keeping expected user-correctable outcomes in state makes them available to the same UI that displays successful results.
Understand queued actions
useActionState queues calls so each action receives the result of the previous call. A sequence of asynchronous operations can therefore take longer when several submissions are queued. React suggests considering useOptimistic or, in more complex cases, cancelling queued actions or not using useActionState.
Cancellation is not a rollback mechanism: stopping client-side work does not undo a server-side mutation that has already happened. Only cancel when the side effect can safely be ignored or retried.

Why is useFormStatus pending always false?
The component calling useFormStatus must be a descendant rendered inside the form being observed. Calling the hook in the same component that creates the <form> does not make it track that form.
Move the hook into a nested submit button or status component, then render that component between the form’s opening and closing tags. Also check that the form uses an action submission that the hook can observe; useFormStatus reports parent-form status, not arbitrary asynchronous work elsewhere in the component.

When should you use one hook or both?
- Use
useActionStatewhen the action returns information the interface must retain and display, such as field errors, a confirmation, or updated data. - Use
useFormStatuswhen a nested control or message needs the parent form’s submission status, method, submitted data, or action reference. - Use both when the form needs to display its action result and give a nested control immediate submission feedback.
- If pending status alone is enough, a nested
useFormStatusconsumer may be sufficient; you do not need action-result state just to show that a form is submitting.
What changes with Server Functions and progressive enhancement?
In a framework that supports React Server Components, a Server Function used with useActionState can return a response that is displayed before hydration completes. This behavior is specific to that Server Function and framework scenario; it is not a blanket guarantee for every client-only form.

The optional permalink argument supports progressive enhancement on dynamic pages using a Server Function. If someone submits before JavaScript loads, the browser can navigate to the permalink. The destination must render the same form component, action, and permalink for React to pass the state through. Once the form is hydrated, the permalink has no effect. See the React reference for its constraints.
The reviewed official references do not state a minimum React version or a complete framework compatibility matrix. Do not infer either from the hook names or from older naming history. The React 19 RC announcement dated April 25, 2024 records that useActionState was previously named useFormState in Canary; that historical note is not a current minimum-version guarantee.
Which React documentation covers form actions?
React’s form reference explains the form action prop. Its Built-in React DOM Hooks overview covers web-specific hooks, including useFormStatus. Together with the individual hook references, these pages clarify how action results, form status, and form submission fit together.
