Handle pending and error states

The createAsync primitive is designed to work with Solid's native components for managing asynchronous states. It reports its pending state to the nearest <Suspense> boundary to display loading fallbacks, and propagate errors to an <ErrorBoundary> for handling and displaying error messages.

import { Suspense, ErrorBoundary, For } from "solid-js";
import { query, createAsync } from "@solidjs/router";

const getNewsQuery = query(async () => {
  // ... Fetches the latest news from an API.
}, "news");

function NewsFeed() {
  const news = createAsync(() => getNewsQuery());

  return (
    <ErrorBoundary fallback={<p>Could not fetch news.</p>}>
      <Suspense fallback={<p>Loading news...</p>}>
        <ul>
          <For each={news()}>{(item) => <li>{item.headline}</li>}</For>
        </ul>
      </Suspense>
    </ErrorBoundary>
  );
}
