React + BlueImp Gallery 🌄

NOW! Your favorite gallery as a React component ;)

This project is a tribute to a wonderful tool as BlueImp Gallery mixed with an awesome devel sandbox like Storybook. As a result we have a useful React component for a flexible slideshow gallery.

☝️How to start

install Reactive Blueimp Gallery in your project npm install --save reactive-blueimp-gallery

✌️Usage

import the library into your component

import ReactGallery from 'reactive-blueimp-gallery';

Set a source with minimum requirements

const images = [{
  source: 'images/banana.jpg',
}, {
  source: 'images/apples.jpg',
}, {
  source: 'images/orange.jpg',
}];

Use the component

<ReactGallery source={images} />

and that's it! 🙌 a working version of BlueImp gallery into your React application 💪.

Options

As a HOC, this lib has some shortcut configurations for a full list of options that BlueImp Gallery offers.

ReactBlueImpGallery accepts the following props:

Property	Type	Description
id	number	just an element identifier, attribute rendered into gallery HTML.
className	string	class name to handle presentational aspects, attribute rendered into gallery HTML.
withControls	boolean	to initialize the Gallery with visible controls. <ReactGallery withControls source={images} />
inlineCarousel	boolean	to display the images in an inline carousel instead of a lightbox. <ReactGallery inlineCarousel source={images} />
options	object	to send to BlueImp Gallery any of the supported options. <ReactGallery options={{ transitionSpeed: 200, }} source={images} />
overlays	ReactBlueImpGallery.Overlays	to send custom overlays for slides. Lets talk about this in the next section.

And finally, into options prop you can find a useful custom event onopen that return the original BlueImp Gallery instance allowing API control. See full API methods here

<ReactGallery
  options={{
    onopen: gal => gal.pause(),
  }}
  source={images}
/>

Custom Overlays

Reactive BlueImp Gallery come with a helper component to customize slides overlay. Overlays component allows you to include extra HTML elements over a slide and also has props to quick set up for existing elements. Overlays is part of ReactBlueImpGallery and can be accesed as an attribute of it.

const customOverlays = (
  <ReactGallery.Overlays>
    <p className="footer-copywrite">&reg; 2017 All rights reserved</p>
  </ReactGallery.Overlays>
);
<ReactGallery
  overlays={customOverlays}
  source={images}
/>

In the example above we're adding a <p> element into default slide overlay. Also you can define Overlays props

Property	Type	Description
className	string	to specify overlay CSS.
noTitle	boolean	to hide default title element.
noArrows	boolean	to hide default arrows (next/prev) elements.
noClose	boolean	to hide default close (x) element.
noPlayPause	boolean	to hide default play/pause element. <ReactGallery overlays={<ReactGallery.Overlays noPlayPause noTitle />} source={images} />
noIndicator	boolean	to hide default slide indicator (ooo) elements.

Slides

The slide component it also comes as ReactBlueImpGallery property. In the first example of this page, the slide component is receiving just one prop but they can accept others.

Property	Type	Description
source	string	for image or video resource, this is an alias of `href` also valid for images but not for video slides.
thumbanil	string	to set a resource to show in thumbanils. `source` will be used if `thumbnails` is undefined.
type	string	to set slide mime type. `image/jpeg` by default.
title	string	info to show in the slide overlay.

✨ Slides with React content 🚀

BlueImp Gallery supports different slide types with a very good approach to customize content types. This way it supports HTML5, Youtube and Vimeo videos. Taking advantage of that smart design, this lib add a new content type to handle slide content with React components.

The content type is text/react (no real mime type for React) and you can implement your React component like the following example.

const MyReactSlideContent = () => {
  return <p>My React slide content</p>;
}

...

<ReactGallery>
  <ReactGallery.Slide
    thumbnail="images/thumbnails/banana.jpg"
    type="text/react" // to tell BlueImp Gallery which slide factory should use
  >
    <MyReactSlideContent />
  </ReactGallery.Slide>
</ReactGallery>

Of course you can have (or you'll need in real life scenarios) dynamic data into your React slide content, but if you need data from a parent component there's a little bit complex issue to solve. Since BlueImp Gallery is in charge of the slide render with vanilla javascript, React lost control of that HTML. In order to let React to render the slides, we're calling ReactDom method to draw custom component into the slide, but that way the scope of the component you wrote and the scope of the instance of your component into the slide are different. Then, a solution is an explicit definition of the data which should be sent to rendered instance of your componente. That can be achived setting a Slide prop called SynchedData like this

const MyReactSlideContent = ({ slideCount }) => {
  return <p>My React slide content with {slideCount}</p>;
}

...

<ReactGallery>
  <ReactGallery.Slide
    thumbnail="images/thumbnails/banana.jpg"
    type="text/react" // to tell BlueImp Gallery which slide factory should use
    synchedData={{ slideCount: this.state.slideCount }} // this prop will be sent to <MyReactSlideContent />
  >
    <MyReactSlideContent />
   </ReactGallery.Slide>
</ReactGallery>

Though this approach really works (you can see it here), you sould be very cautious about implementing React components architecture into slide contents.
