useActionDataReturns the serialized data from the most recent route action or undefined if there isn't one. This hook only returns action data from the route in context - it can not access data from other parent or child routes.
import type { ActionFunctionArgs } from "@remix-run/node"; // or cloudflare/deno
import { json } from "@remix-run/node"; // or cloudflare/deno
import { Form, useActionData } from "@remix-run/react";
export async function action({
request,
}: ActionFunctionArgs) {
const body = await request.formData();
const name = body.get("visitorsName");
return json({ message: `Hello, ${name}` });
}
export default function Invoices() {
const data = useActionData<typeof action>();
return (
<Form method="post">
<input type="text" name="visitorsName" />
{data ? data.message : "Waiting..."}
</Form>
);
