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 🙏

Install the package using NPM:

npm install react-magnifier

import Magnifier from 'react-magnifier';
import yourImage from './path/to/image';

// Somewhere in your code:
<Magnifier src={yourImage} width={500} />

Configuration

Prop | Type | Default | Description ---- | ---- | ------- | ----------- src (required) | String | – | URL/path of the large image height | Number/String | 'auto' | Image height (absolute or relative values possible) width | Number/String | '100%' | Image width (absolute or relative values possible) className | String | '' | Class which will be applied to the image wrapper zoomImgSrc | String | – | URL/path of the image inside the magnifying glass (if not specified, the large image will be used) zoomFactor | Number | 1.5 | Factor by which the zoom image will be scaled (based on the size of the large image) mgWidth | Number | 150 | Width of the magnifying glass in px mgHeight | Number | 150 | Height of the magnifying glass in px mgBorderWidth | Number | 2 | Border width of the magnifying glass in px mgShape | String | 'circle' | Shape of the magnifying glass (possible values: 'circle', 'square') mgShowOverflow | Boolean | true | Set this to false to cut off the magnifying glass at the image borders mgMouseOffsetX | Number | 0 | Horizontal offset of the magnifying glass in px when hovering with a mouse mgMouseOffsetY | Number | 0 | Vertical offset of the magnifying glass in px when hovering with a mouse mgTouchOffsetX | Number | -50 | Horizontal offset of the magnifying glass in px when dragging on a touch screen mgTouchOffsetY | Number | -50 | Vertical offset of the magnifying glass in px when dragging on a touch screen

Any other props will be passed down to the <img> element.
