Asynchronous dynamic data at scale. Performance, data integrity, and typing for [REST](https://resthooks.io/rest), proto, [GraphQL](https://resthooks.io/graphql), [websockets](https://resthooks.io/docs/api/Manager#middleware-data-stream) and [more](https://resthooks.io/docs/guides/img-media)..

### Simple [TypeScript definition](https://resthooks.io/rest/api/Entity)
```typescript
class Article extends Entity {
readonly id: string = '';
readonly title: string = '';
readonly body: string = '';
pk() {
return this.id;
}
}
```
### Create [collection of API Endpoints](https://resthooks.io/rest/api/createResource)
```typescript
const ArticleResource = createResource({
path: '/articles/:id',
schema: Article,
})
```
### One line [data binding](https://resthooks.io/docs/api/useSuspense)
```tsx
const article = useSuspense(ArticleResource.get, { id });
return (
<>
{article.title}
{article.body}
);
```
### [Mutation](https://resthooks.io/docs/getting-started/mutations)
```tsx
const ctrl = useController();
return (
ctrl.fetch(ArticleResource.update, { id }, data)}
/>
);
```
### And [subscriptions](https://resthooks.io/docs/api/useSubscription)
```tsx
const price = useSuspense(PriceResource.get, { symbol });
useSubscription(PriceResource.get, { symbol });
return price.value;
```
### [Programmatic queries](https://resthooks.io/rest/api/Query)
```tsx
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 });
```
