Simple TypeScript definition

class Article extends Entity {
  id = '';
  title = '';
  body = '';

  pk() {
    return this.id;
  }
}

Create collection of API Endpoints

const ArticleResource = createResource({
  path: '/articles/:id',
  schema: Article,
})

One line data binding

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

Mutation

const ctrl = useController();
return (
  <ArticleForm
    onSubmit={data => ctrl.fetch(ArticleResource.update, { id }, data)}
  />
);

Subscriptions

const price = useLive(PriceResource.get, { symbol });
return price.value;

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 });

...all typed ...fast ...and consistent
