Handling revalidation of a particular article requires us to pass through an ID as part of the request's body. Therefore, we need to change this from a GET request to a POST request and use the withContent middleware to parse the request's body into a JSON object.

Additionally, we fetch data for this specific article from Supabase, using its ID, and update the cache for that path.

We can no longer test this using a browser, as it can only send GET requests. Therefore, we use a VS Code extension called Thunder Client to make the POST request and pass along the article's ID in the request's body.

Code Snippets

Update Revalidate route for single article

router.post(
  "/revalidate",
  withContent,
  async (request, { SUPABASE_URL, SUPABASE_ANON_KEY, ARTICLES }) => {
    const { id } = request.content;
    const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY);

    const { data: article } = await supabase
      .from("articles")
      .select("*")
      .match({ id })
      .single();
    await writeTo(ARTICLES, `/articles/${id}`, article);

    const { data: articles } = await supabase.from("articles").select("*");
    await writeTo(ARTICLES, "/articles", articles);

    return json({ received: true });
  }
);
