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

use-broadcast-channel (React-hooks)

The Broadcast Channel API allows basic communication between browsing contexts (that is, windows, tabs, frames, or iframes) and workers on the same origin. -MDN

This package provides a thin wrapper around the browser's native Broadcast Channel API in the form of a React hook function. The hook(s) can be used in any React component or custom hook to harness the functionality of Broadcast Channel API.

To use the hooks in browsers that do not support Broadcast Channel API, install and import broadcastchannel-polyfill.

For typescript users: The default data-type for all messages are set to string but can be easily overridden by explicitly passing type parameter to the hook(s). Example for numeric data: useBroadcastChannel<number>("count", (e) => console.log(e.data));

Setup

Package available at NPM.

  • NPM

    npm install use-broadcast-channel
  • Yarn

    yarn add use-broadcast-channel

API

The package exports multiple hooks for different use-cases.

useBroadcastChannel hook

React hook to create and manage a Broadcast Channel across multiple browser windows/tabs/frames. This is base hook exported by the package as all other exported hooks depends on it.

- Read-only

Only subscribe for events broadcasted on a particular channel.

import { useBroadcastChannel } from "use-broadcast-channel";

function App() {
  useBroadcastChannel("userId", (e) => alert(e.data));
  return null;
}

- Write-only

Only broadcast (post) event on a particular channel.

import { useBroadcastChannel } from "use-broadcast-channel";

function App() {
  const postUserId = useBroadcastChannel("userId");
  return <button onClick={() => postUserId("ABC123")}>Post UserId</button>;
}

- Read and Write

Both broadcast (post) event and subscribe for events broadcasted on a particular channel.

import { useBroadcastChannel } from "use-broadcast-channel";

function App() {
  const postUserId = useBroadcastChannel("userId", (e) => alert(e.data));
  return <button onClick={() => postUserId("ABC123")}>Send UserId</button>;
}

useBroadcastState hook

React hook to manage state across browser windows/tabs/frames. It has a similar signature as React.useState. It used useBroadcastChannel under the hood.

import { useBroadcastState } from "use-broadcast-channel";

function App() {
  const [count, setCount] = useBroadcastState("count", 0);
  return (
    <div>
      <button onClick={() => setCount((prev) => prev - 1)}>Decrement</button>
      <span>{count}</span>
      <button onClick={() => setCount((prev) => prev + 1)}>Increment</button>
    </div>
  );
}
