collection of API Endpoints
Createconst ArticleResource = createResource({

data binding
One lineconst article = useSuspense(ArticleResource.get, { id });
return (
<>
<h2>{article.title}</h2>
<p>{article.body}</p>
</>

Mutation
const ctrl = useController();

subscriptions
Andconst price = useLive(PriceResource.get, { symbol });

Programmatic queries
const sortedArticles = new Query(
new schema.All(Article),
(entries, { asc } = { asc: false }) => {
const sorted = [...entries].sort((a, b) => a.title.localeCompare(b.title));
if (asc) return sorted;
return sorted.reverse();
}
);
const articlesUnsorted = useCache(sortedArticles);
const articlesAscending = useCache(sortedArticles, { asc: true });
const articlesDescending = useCache(sortedArticles, { asc: false });
