A React component for magnifying an image within its original container. The zoom behavior is triggered on click and includes default image panning on hover that switches to drag to move if a touch device is detected. The component supports responsive images and optional fullscreen zoom on mobile.
npm install react-inner-image-zoom
yarn add react-inner-image-zoom
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.

Most of the implementation choices for this component are based on use cases I've encountered in the past. For example, I chose a click to zoom trigger because it's been the most requested on product detail pages I've worked on. If there's a demand for zoom on hover or other additional functionality, I'd be open to looking into it so feel free to ask.
