函数 useAsyncError

从最近的 <Await> 返回 rejection 值。

import { Await, useAsyncError } from "react-router"

function ErrorElement() {
  const error = useAsyncError();
  return (
    <p>Uh Oh, something went wrong! {error.message}</p>
  );
}

// somewhere in your app
<Await
  resolve={promiseThatRejects}
  errorElement={<ErrorElement />}
/>
