React Component & Image Lightbox

Same as lightbox-react, but autorotates images based on exif data.

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 rendered as a child React component of the lightbox.

Originally forked from fritz-c's library

And then forked from treyhuffine's one

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

import React, { Component } from 'react';
import Lightbox from 'lightbox-react-with-autorotate';
import VideoIframe from 'components/cat-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 (
            <div>
                <button
                    type="button"
                    onClick={() => this.setState({ isOpen: true })}
                >
                    Open Lightbox
                </button>

                {isOpen &&
                    <Lightbox
                        mainSrc={images[photoIndex]}
                        nextSrc={images[(photoIndex + 1) % images.length]}
                        prevSrc={images[(photoIndex + images.length - 1) % images.length]}

                        onCloseRequest={() => this.setState({ isOpen: false })}
                        onMovePrevRequest={() => this.setState({
                            photoIndex: (photoIndex + images.length - 1) % images.length,
                        })}
                        onMoveNextRequest={() => this.setState({
                            photoIndex: (photoIndex + 1) % images.length,
                        })}
                    />
                }
            </div>
        );
    }
}
