Typing REST Endpoints

In REST design, many operations can be performed on a given type of data.

Attaching these operations to the type via static methods allows

  • A singular import for both class usage, typing, and endpoints
  • Reducing code duplication by extracting common patterns into base classes

Resource provides one such pattern, which makes getting started fast. However, even if the pattern generally matches your API design, there are often special operations or one-off cases where additional endpoints must be extended or added.


Here's an example of each endpoint's return typed followed by usage. For a full explanation, continue reading below.

import { Resource, ReadShape, MutateShape, AbstractInstanceType } from 'rest-hooks';

class MyResource extends Resource {
static list<T extends typeof Resource>(
this: T,
): ReadShape<AbstractInstanceType<T>[]> {
return super.list();

static create<T extends typeof Resource>(
this: T,
): MutateShape<AbstractInstanceType<T>> {
return super.create();

static filteredAndPaginatedList<T extends typeof Resource>(
this: T,
): MutateShape<
{ results: AbstractInstanceType<T>[]; nextPage: string }
> {
return super.list();
import MyResource from 'resources/MyResource';
import { useResource } from 'rest-hooks';

const items = useResource(MyResource.list(), {});
const createMy = useFetcher(MyResource.create());
const { results, nextPage } = useResource(
{ filterA: true, sortby: 'first' },
