useLoading

Hooks that make it easy to manage the loading state of a Promise.

useLoading returns a Tuple of [isLoading: boolean, startLoading: (promise: Promise) => Promise].

• The first value, isLoading, initially starts with false.
• The second value, startLoading, is a function that returns a promise.
  • When startLoading is executed and the promise given as an argument is resolved, isLoading becomes true.
  • If that Promise then resolves, isLoading becomes false again.

See the example below to see exactly how to use useLoading.

const [isLoading, startLoading] = useLoading();

Examples

function postConfirmation(data: Data): Promise<Result> {
  return post.e2e<Result>('/api/sample/confirm', data);
}

function ConfirmButton({ data }: { data: Data }) {
  const [loading, startTransition] = useLoading();

  const handleSubmit = useCallback(() => {
    const result = await startTransition(postConfirmation(data));
    router.push(`/success?id=${result.id}`);
  }, [call]);

  return (
    <Button loading={loading} onClick={handleSubmit}>
      GoGo
    </Button>
  );
}
