React Component & Image Lightbox

NPM

See it in action on gitconnected - The Developer Community

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

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 (
      <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>
    );
  }
}

Deprecation Notice

All unprefixed classes (listed below) will be removed in v4.0.0. Use their ril- prefixed alternatives instead. close, closing, download-blocker, image-current, image-next, image-prev, inner, next-button, not-loaded, outer, prev-button, toolbar, toolbar-left, toolbar-right, zoom-in, zoom-out

Options

Property Type Default Required Description
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.
onImageLoadError func empty function Called when an image fails to load.
<code>(imageSrc: string, srcType: string, errorEvent: object): void</code>
discourageDownloads bool false Enable download discouragement (prevents [right-click -> Save Image As...])
animationDisabled bool false Disable all animation
animationOnKeyInput bool false Disable animation on actions performed with keyboard shortcuts
animationDuration number 300 Animation duration (ms)
keyRepeatLimit number 180 Required interval of time (ms) between key actions (prevents excessively fast navigation of images)
keyRepeatKeyupBonus number 40 Amount of time (ms) restored after each keyup (makes rapid key presses slightly faster than holding down the key to navigate images)

imageCaption node Image caption (Descriptive element below image)
toolbarButtons node[] Array of custom toolbar buttons
reactModalStyle Object {} Set z-index style, etc., for the parent react-modal (react-modal style format)
