💡 Hint

Common Mistakes

Using a generic 'id' instead of the specific parameter name.

Not importing useParams from Remix.

The dynamic parameter matches the file name segment $userId, so use params.userId.

4fill in blank

hard

Fill both blanks to create a loader that fetches data using the dynamic parameter and returns JSON.

Remix

export async function loader({ [1] }) {
  const id = [2].id;
  const data = await fetchDataById(id);
  return json(data);
}

💡 Hint

Common Mistakes

Using 'request' instead of 'params' to get route parameters.

Trying to access id directly without params.

The loader receives an object with params. Use params.id to get the dynamic parameter.

5fill in blank

hard

Fill all three blanks to create a Remix route component that uses the loader data and dynamic parameter.

Remix

import { useLoaderData, useParams } from '@remix-run/react';

export default function Post() {
  const data = useLoaderData();
  const [1] = useParams();
  return (
    <main>
      <h1>Post ID: [2].id</h1>
      <p>{data.content}</p>
    </main>
  );
}

export async function loader({ [3] }) {
  const post = await getPostById([3].id);
  return json(post);
}
