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

useElementSize Hook

useElementSize is a React hook that enables dynamic tracking of an HTML element's dimensions. It updates the element's width and height in response to window resizing, element mounting/unmounting, and ref changes.

Features

  • Dynamic Dimension Tracking: Automatically tracks and updates the width and height of the specified element.
  • Responsive to Environmental Changes: Responds to window resizing and ref changes, ensuring accurate size measurements.
  • SSR Safe: Compatible with server-side rendering, avoiding errors in environments without a window object.
  • Optimized for Accuracy: Uses useLayoutEffect for precise dimension measurements after DOM mutations.

Installation

Choose and install individual hooks that suit your project needs, or install the entire collection for a full suite of utilities.

Installing Only Current Hooks

npm install @custom-react-hooks/use-element-size

or

yarn add @custom-react-hooks/use-element-size

Installing All Hooks

npm install @custom-react-hooks/all

or

yarn add @custom-react-hooks/all

Importing the Hook

The useElementSize hook must be imported using a named import as shown below:

Named Import:

import { useElementSize } from '@custom-react-hooks/use-element-size';

This approach ensures that the hook integrates seamlessly into your project, maintaining consistency and predictability in how you use our package.

Usage

import React, { useRef, useState } from 'react';
import { useElementSize } from '@custom-react-hooks/all';

const ElementSizeComponent = () => {
  const [setRef, size] = useElementSize();

  return (
    <div className="element-size">
      <div
        ref={setRef}
        className="resize"
      >
        <p>Drag from the bottom-right corner to resize.</p>
      </div>
      <br />
      <div>Current Size:</div>
      <div className="btns">
        <p>
          Width: <span>{size.width}px</span>
        </p>
        <p>
          Height: <span>{size.height}px</span>
        </p>
      </div>
    </div>
  );
};

export default ElementSizeComponent;

In this example, useElementSize is used to measure and display the dimensions of a div element.
