Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

react-fetcher-hook

v1.0.2

Published

Fetching data with use + suspense in React 19+

Readme

useFetch for React 19+

You can read this readme in English.

Motivation / Features

Этот хук не возвращает результат запроса, состояние загрузки или ошибку.

Он возвращает промис, который можно обработать в стиле react 19+ с помощью хука use / Suspense и ErrorBoundary.

  • [x] Использование хука use из react 19+ для ожидания данных
  • [x] Использование компонента Suspense для ожидания данных
  • [x] Использование компонента ErrorBoundary для отлова ошибок
  • [x] Автоматическая отмена запроса при размонтировании компонента (актуально для StrictMode)

Installation

$ npm install react-fetcher-hook

Usage

import { Suspense, use } from "react";
import { ErrorBoundary } from "react-error-boundary";
import useFetch from 'react-fetcher-hook';

const service = () => fetch('https://jsonplaceholder.typicode.com/todos/1').then(res => res.json());

const Example: FC = () => {
  const { promise, fetcher } = useFetch(service);

  return (
    <>
      <Button onClick={fetcher}>get todo</Button>

      <ErrorBoundary fallback={<>Something was wrong!</>}>
        <Suspense fallback={<>Loading...</>}>
          <TodoData promise={promise} />
        </Suspense>
      </ErrorBoundary>
    </>
  )
};

const TodoData: FC<{ promise: Promise<any> }> = props => {
  const { promise } = props;
  const todo = use(promise);

  return (
    <>
      {JSON.stringify(todo, null, 2)}
    </>
  );
};

Abortable Requests (for StrictMode)

const service = (signal: AbortSignal) => {
  const url = 'https://jsonplaceholder.typicode.com/todos/1';
  return fetch(url, { signal }).then(res => res.json());
}

Request with Arguments

Вы можете передать любое количество аргументов в функцию service. Если у функции service последний аргумент имеет тип AbortSignal, то запрос будет отменяемым.

const service = (entity: string, id: number, signal: AbortSignal) => {
  const url = `https://jsonplaceholder.typicode.com/${entity}/${id}`;
  return fetch(url, { signal }).then(res => res.json());
}

API

useFetch(service, initial?)

parms

  • service(...args: Array<any>, signal?: AbortSignal) => Promise<any> - async function
  • initial - initial value for promise (default: undefined)

returns

  • { promise: Promise<any>, fetcher: (...args: Array<any>) => void }
