React Component & Image Lightbox


$3

A lightbox for React components or images. String passed as arguments are
assumed to be the src for an image. Otherwise, it will check if the argument
is able to be rended as a child React component of the lightbox.

DEMO

Originally forked from fritz-c's library

Features

- Keyboard shortcuts (with rate limiting)
- Image Zoom
- Flexible rendering using src values assigned on the fly
- Image preloading for smoother viewing
- Mobile friendly, with pinch to zoom and swipe (Thanks, @webcarrot!)
- No external CSS

Example

``jsx
import React, { Component } from 'react';
import Lightbox from 'lightbox-react';
import 'lightbox-react/style.css'; // This only needs to be imported once in your app

import VideoIframe from 'components/video';

const images = [
VideoIframe,
'//placekitten.com/1500/500',
'//placekitten.com/4000/3000',
'//placekitten.com/800/1200',
'//placekitten.com/1500/1500',
];

export default class LightboxExample extends Component {
constructor(props) {
super(props);

this.state = {
photoIndex: 0,
isOpen: false,
};
}

render() {
const { photoIndex, isOpen } = this.state;

return (



);
}
}
`

| mainSrc | string | | yes | Main display image url or React component |
| prevSrc | string | | | Previous display image url or component (displayed to the left). If left undefined, onMovePrevRequest will not be called, and the button not displayed |
| nextSrc | string | | | Next display image url or component (displayed to the right). If left undefined, onMoveNextRequest will not be called, and the button not displayed |
| mainSrcThumbnail | string | | | Thumbnail image url corresponding to props.mainSrc. Displayed as a placeholder while the full-sized image loads. |
| prevSrcThumbnail | string | | | Thumbnail image url corresponding to props.prevSrc. Displayed as a placeholder while the full-sized image loads. |
| nextSrcThumbnail | string | | | Thumbnail image url corresponding to props.nextSrc. Displayed as a placeholder while the full-sized image loads. |
| onCloseRequest | func | | yes | Close window event. Should change the parent state such that the lightbox is not rendered |
| onMovePrevRequest | func | empty function | | Move to previous image event. Should change the parent state such that props.prevSrc becomes props.mainSrc, props.mainSrc becomes props.nextSrc, etc. |
| onMoveNextRequest | func | empty function | | Move to next image event. Should change the parent state such that props.nextSrc becomes props.mainSrc, props.mainSrc becomes props.prevSrc, etc. |

| animationDuration | number | 300 | | Animation duration (ms) |
| keyRepeatLimit | number | 180 | | Required interval of time (ms) between key actions (prevents excessively fast navigation of images) |

| toolbarButtons | node[] | | | Array of custom toolbar buttons |
