Simple TypeScript definition

class ArticleResource extends Resource {
  readonly id: string = '';
  readonly title: string = '';
  readonly body: string = '';

  pk() {
    return this.id;
  }
  static urlRoot = '/articles/';
}

One line data hookup

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

Mutation

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

And subscriptions

const price = useSuspense(PriceResource.detail(), { symbol });
useSubscription(PriceResource.detail(), { symbol });
return price.value;

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

Principals of Rest Hooks

Integrity

• Strong inferred types
• Global referential equality guarantees
• Normalized store creates a single source of truth
• Strong invariants robust against race conditions
• Validation

Performance

• Stale While Revalidate configurable cache
• Only re-render

Composition over configuration

• Declarative data definitions
• Decoupled API definitions from usage
• Co-located data dependencies
  • Centralized orchestration
• Extensible orchestration through Managers (middleware)
• Composable hooks
  • subject pattern
• Suspense + concurrent mode async orchestration

Incremental Adoption

• Simple case is simple
• Scale as your app scales
