Data Client for REST

Extensible CRUD patterns for REST APIs.

📖Read The Docs  |  🎮Github Demo

Simple TypeScript definition

import { Entity, createResource } from '@data-client/rest';

class Article extends Entity {
  id: number | undefined = undefined;
  title = '';
  body = '';

  pk() {
    return this.id;
  }
}
const ArticleResource = createResource({
  path: '/articles/:id',
  schema: Article,
});

Entity defines a data model. createResource creates a collection of six RestEndpoints

RestEndpoints are functions (and more) that return a Promise. Both call parameters and return value are automatically inferred from the options used to construct them.

path is a templating language using path-to-regex compile.

Standard CRUD Endpoints

Reads

const article = useSuspense(ArticleResource.get, { id: 5 });
const articles = useSuspense(ArticleResource.getList);

const [article, setArticle] = useState();
useEffect(() => {
  setArticle(await ArticleResource.get({ id: 5 }));
}, []);

Mutates

const ctrl = useController();
const updateArticle = data => ctrl.fetch(ArticleResource.update, { id }, data);
const partialUpdateArticle = data =>
  ctrl.fetch(ArticleResource.partialUpdate, { id }, data);
const createArticle = data => ctrl.fetch(ArticleResource.create, data);
const deleteArticle = data => ctrl.fetch(ArticleResource.delete, { id });

Use with Node

const article = await ArticleResource.get({ id: 5 });
const articles = await ArticleResource.getList();

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 });

TypeScript requirements

TypeScript is optional, but will only work with 4.0 or above. 4.1 is needed for stronger types as it supports inferring argument types from the path templates.

Version 5.x can be used for older TypeScript versions.
