react-inner-image-zoom

A React component for magnifying an image within its original container. The zoom behavior is triggered on click and the image can be moved by dragging on touch devices and by either dragging or hover panning on non-touch devices. The component supports responsive images and optional fullscreen zoom on mobile.

Installation

NPM

npm install react-inner-image-zoom

Yarn

yarn add react-inner-image-zoom

Styling

I was originally importing the CSS directly into the component but I've recently realized that makes too many assumptions about the wider build process. You can now download the raw CSS file at:

/src/InnerImageZoom/styles.css

or the minified raw minified version at:

/src/InnerImageZoom/styles.min.css

to include however you see fit. Or, if your setup supports it, import the files directory from your node_modules using:

import 'react-inner-image-zoom/lib/InnerImageZoom/styles.css';

or:

import 'react-inner-image-zoom/lib/InnerImageZoom/styles.min.css';

Usage

Import and render the component:

import InnerImageZoom from 'react-inner-image-zoom';

...

<InnerImageZoom src="/path/to/image.jpg" zoomSrc="/path/to/zoom-image.jpg" />

This is the simplest usage. For additional examples, visit the demo page.

Sources

This prop accepts an array of objects which it uses to create a picture tag and source elements. The component looks for the following optional properties and you can find additional details on responsive images here:

Prop Type Default Description
srcSet String Srcset attribute for source tag.
sizes String Sizes attribute for source tag.
media String An attribute containing a media condition for use with the srcset.
type String An image MIME type. This is useful for using newer formats like WebP.
