Asynchronous mutable data at scale. Performance, data integrity, and typing for REST, proto, GraphQL, websockets and more..
Simple TypeScript definition
class Article extends Entity {
readonly id: string = '';
readonly title: string = '';
readonly body: string = '';
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>
</>
);
const ctrl = useController();
return (
<ArticleForm
onSubmit={data => ctrl.fetch(ArticleResource.update, { id }, data)}
/>
);
And subscriptions
const price = useSuspense(PriceResource.get, { symbol });
useSubscription(PriceResource.get, { symbol });
return price.value;
const sortedArticles = new schema.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 = useQuery(sortedArticles);
const articlesAscending = useQuery(sortedArticles, { asc: true });
const articlesDescending = useQuery(sortedArticles, { asc: false });
