Signature

function useActionData<T = RouteModule>(
  route?: T & LoaderSource,
): ActionData<T> | undefined;

Parameters

Optionally pass a typed route object or an action function type generic.

Returns

Inferred action result or undefined.

Usage

Import this API from one of the entry points listed above. Keep server and build helpers in their dedicated subpaths.

const result = useActionData<typeof action>();

return <p>{result?.message}</p>;

Behavior and edge cases

Fetcher action results belong to fetcher.data and are not returned here. Navigating to another route clears page action data. The hook does not submit anything; use Form or router.submit.
