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 🙏

Readme

react-webworker-hook

A react custom hook to communicate with web worker. just specify the web worker url or a script that you want webworker to run and you will get access to any message, error it sends and postMessage handler which is used to communicate with web worker

Installation

npm install --save react-webworker-hook

Usage

a quick sample here https://codesandbox.io/p/sandbox/react-webworker-hook-example-6xt8rm

import React, { useState } from "react";
import useWebWorker from "react-webworker-hook";

function GenerateFibonacci() {
  const [data = 0, postData] = useWebWorker({
    url: "./webworker_example.js"
  });
  const [count, setCount] = useState(0);

  return (
    <div>
      {`fibonacci for ${count}: ${data}`}
      <button
        onClick={() => {
          setCount(count + 1);
          postData(count);
        }}
      >
        Generate
      </button>
    </div>
  );
}

export default GenerateFibonacci;

It also comes with other helper functions like when we have a small script which should be deployed into webworker

const [data, postData, error] = useWebWorkerFromScript(`
const fib = n => (n < 2 ? n : fib(n - 1) + fib(n - 2));

onmessage = ({ data }) => {
  postMessage(fib(data));
};

`)

pass url of a web worker, webworker should be served from the same origin

const [data, postData, error] = useWebWorkerFromUrl('./webworker_example.js');

when we have an existing worker and it should be used through hook

const [data, postData, error] = useWebWorkerFromWorker('./webworker_example.js');

API

useWebWorker takes following arguments

a config object with either url or worker object

useWebWorker provides following values

  • data - data which has been sent by webworker
  • postMessage - handler which is used to communicatew with webworker
  • error - which will contain an error object if thrown by web worker
