`defer`

该实用程序允许您通过传递承诺而不是解析值来延迟从loader返回的值。

jsx

async function loader() {
  let product = await getProduct();
  let reviews = getProductReviews();
  return defer({ product, reviews });
}

async function loader() {
  let product = await getProduct();
  let reviews = getProductReviews();
  return defer({ product, reviews });
}
