useNavigation

useNavigation(): Navigation

Returns the current navigation, defaulting to an "idle" navigation when no navigation is in progress. You can use this to render pending UI (like a global spinner) or read FormData from a form navigation.

import { useNavigation } from "react-router"

function SomeComponent() {
  let navigation = useNavigation();
  navigation.state
  navigation.formData
  // etc.
}
