useFetchers

useFetchers(): Fetcher & { 
  key: string,
}[]

Returns an array of all in-flight fetchers. This is useful for components throughout the app that didn't create the fetchers but want to use their submissions to participate in optimistic UI.

import { useFetchers } from "react-router";

function SomeComponent() {
  const fetchers = useFetchers();
  fetchers[0].formData; // FormData
  fetchers[0].state; // etc.
  // ...
}
