Basic Usage

import 'photoswipe/dist/photoswipe.css'

import { Gallery, Item } from 'react-photoswipe-gallery'

const MyGallery = () => (
  <Gallery>
    <Item
      original="https://placekitten.com/1024/768?image=1"
      thumbnail="https://placekitten.com/80/60?image=1"
      width="1024"
      height="768"
    >
      {({ ref, open }) => (
        <img ref={ref} onClick={open} src="https://placekitten.com/80/60?image=1" />
      )}
    </Item>
    <Item
      original="https://placekitten.com/1024/768?image=2"
      thumbnail="https://placekitten.com/80/60?image=2"
      width="1024"
      height="768"
    >
      {({ ref, open }) => (
        <img ref={ref} onClick={open} src="https://placekitten.com/80/60?image=2" />
      )}
    </Item>
  </Gallery>
)

Demo

Check out the Storybook to see it in action 🚀

Stories are written as real-world examples, so you can see them at the bottom of Storybook UI in the Story tab. Or browse the source code on GitHub. It covers most of the use-cases and provides examples for configuration options.

Installation

yarn add photoswipe react-photoswipe-gallery

or

npm install photoswipe react-photoswipe-gallery --save

Hash Navigation

You should pass a unique id prop to <Gallery /> component, to enable hash navigation.

Optionally, you can also pass the id to <Item /> component. Otherwise, the index will be used.

const MyGallery = () => (
  <Gallery id="my-gallery">
    <Item
      id="first-pic"
      {/*...*/}
    />
    <Item
      id="second-pic"
      {/*...*/}
    />
  </Gallery>
)

Example

Captions

If you want to add captions to your slides, you need to pass withCaption prop to the <Gallery /> and pass caption prop to each <Item />. It accepts html as well. If caption isn't provided - it will use alt prop.

const MyGallery = () => (
  <Gallery withCaption>
    <Item
      caption="Foo"
      {/*...*/}
    />
    <Item
      alt="Bar"
      {/*...*/}
    />
  </Gallery>
)

Example

Plugins

You can use native PhotoSwipe plugins with plugins prop. It accepts the function in which you should register all of your plugins, providing pswpLightbox to the plugin constructor.

Example for photoswipe-dynamic-caption-plugin:

import 'photoswipe-dynamic-caption-plugin/photoswipe-dynamic-caption-plugin.css'
import PhotoSwipeDynamicCaption from 'photoswipe-dynamic-caption-plugin'

const MyGallery = () => (
  <Gallery
      plugins={(pswpLightbox) => {
        // register plugin
        const captionPlugin = new PhotoSwipeDynamicCaption(pswpLightbox, {
          captionContent: (slide) => slide.data.alt,
        })

        // register another plugin
        // ...
      }}
  >
    {/*...*/}
  </Gallery>
)

Example

Custom UI Elements

You can add custom UI elements to PhotoSwipe with uiElements prop. It accepts an array of configuration objects for custom UI elements.

const uiElements = [
  // add custom UI element
  {
    name: 'custom-button',
    ariaLabel: 'Custom button',
    order: 9,
    isButton: true,
    html: {
      isCustomSVG: true,
      inner:
        '<path d="<ICON_PATH>" id="pswp__icn-cstm-btn"/>',
      outlineID: 'pswp__icn-cstm-btn',
    },
    appendTo: 'bar',
    onInit: (el, pswpInstance) => {
      // do something on UI element's init event
    },
    onClick: (e, el, pswpInstance) => {
      // do something on UI element's click event
    },
  },

  // add another custom UI element
  // ...
]

const MyGallery = () => (
  <Gallery uiElements={uiElements}>
    {/*...*/}
  </Gallery>
)

Example

Custom slide content

You can add your own custom slide content with content and html props.

const MyGallery = () => (
  <Gallery>
    <Item
      content={<h1>Hi!</h1>}
      {/*...*/}
    />
    <Item
      html="<h1>Hi!</h1>"
      {/*...*/}
    />
  </Gallery>
)

Example

Access to Photoswipe instance

If you need to get access to Photoswipe instance (for example, to subscribe on Photoswipe events or call some Photoswipe method), you can do it via onOpen and onBeforeOpen props of Gallery component.

onBeforeOpen triggers before PhotoSwipe.init() call.

onOpen triggers after PhotoSwipe.init() call.

onBeforeOpen and onOpen will receive PhotoSwipe instance as the first argument.

const onBeforeOpen = (pswpInstance) => {
  pswpInstance.on('change', () => {
    console.log('slide was changed')
  })
}

const onOpen = (pswpInstance) => {
  pswpInstance.currSlide.zoomTo(
    1,
    { x: 0, y: 0 },
    2000,
    false
  )
}

const MyGallery = () => (
  <Gallery onBeforeOpen={onBeforeOpen} onOpen={onOpen}>
    {/*...*/}
  </Gallery>
)

Photoswipe customization

If you need to customize Photoswipe options or Photoswipe styling you can do it via options prop of Gallery component.

const options = {
  arrowPrev: false,
  arrowNext: false,
  zoom: false,
  close: false,
  counter: false,
  bgOpacity: 0.2,
  padding: { top: 20, bottom: 40, left: 100, right: 100 },
}

const MyGallery = () => (
  <Gallery options={options}>
    {/*...*/}
  </Gallery>
)

   * It must be set to HTML Element in order to work.
   * Can be done like usual ref: ref={ref}
   * or callback-way if you need extra work done with node:
   * ref={(node) => {
   *   ref(node)
   *   ...
   * }}
   */
  ref: (node: NodeType | null) => void

  /**
   * Function that opens the gallery at the current item
   */
  open: (e: MouseEvent) => void
}

<Item>
  {({ ref, open }) => (
    <img ref={ref} onClick={open} />
  )}
</Item>

<Item>
  {({ ref, open }) => (
    <span
      ref={(node) => {
        ref(node)
        console.log(node)
      }}
      onClick={open}
    >
      Open gallery
    </span>
  )}
</Item>

Hooks

useGallery

The useGallery hook returns an object with some useful methods.

Property Type Description
open (index: number) => void This function allows programmatically open Photoswipe UI at index

useGallery hook gets context provided by Gallery component. So to use useGallery hook you need to store your gallery content as separate component and then wrap it into Gallery component.

const GalleryContent = () => {
  const { open } = useGallery()

  useEffect(() => {
      open(1) // you can open second slide by calling open(1) in useEffect
  }, [open])

  return (
    <div>
      {/* or you can open second slide on button click */}
      <button onClick={() => open(1)}>Open second slide</button>
      <div>
        <Item>...</Item>
        <Item>...</Item>
        <Item>...</Item>
      </div>
    </div>
  )
}

const MyGallery = () => {
  return (
    {/* Gallery component provides context for useGallery hook used in GalleryContent */}
    <Gallery>
      <GalleryContent />
    </Gallery>
  )
}
