@react-spring/parallax v10.0.1

@react-spring/parallax

yarn add @react-spring/parallax

NOTE: Currently, only @react-spring/web is supported.

Parallax creates a scrollable container. ParallaxLayers contain your content and will be moved according to their offsets and speeds.

import { Parallax, ParallaxLayer } from '@react-spring/parallax'

const Example = () => {
  const ref = useRef()
  return (
    <Parallax pages={3} ref={ref}>
      <ParallaxLayer offset={0} speed={2.5}>
        <p>Layers can contain anything</p>
      </ParallaxLayer>

      <ParallaxLayer offset={1} speed={-2} factor={1.5} horizontal />

      <ParallaxLayer sticky={{ start: 1, end: 2 }} />

      <ParallaxLayer offset={2} speed={1}>
        <button onClick={() => ref.current.scrollTo(0)}>Scroll to top</button>
      </ParallaxLayer>
    </Parallax>
  )
}

Parallax

ref Properties

Parallax also has a few useful properties that you can access using a ref:

const ref = useRef()
...
<Parallax ref={ref}>

ref.current.scrollTo

A function for click-to-scroll. It takes one paramater: the number of the page to scroll to. Pages are zero-indexed, so scrollTo(0) will scroll to the first page, scrollTo(1) to the second, etc.

ref.current.container

The ref for the outer container div of Parallax, for when you need access to the actual DOM Element.

NOTE: since it is also a ref, it must be accessed with ref.current.container.current.

ref.current.content

The ref for the inner container div of Parallax.

Usage Notes

• All direct children of Parallax must be ParallaxLayers (or fragments whose only direct children are ParallaxLayers).
• Parallax is a scrollable container so all scroll events are fired from the container itself -- listening for scroll on window won't work (but you can use ref.current.container).

ParallaxLayer

Usage Notes

• The offset prop is where the layer will end up, not where it begins. For example, if a layer has an offset of 1.5, it will be halfway down the second page (zero-indexed) when the second page completely fills the viewport.
• The speed prop will affect the initial starting position of a layer, but not it's final offset position.
• Any layer with sticky set will have a z-index higher than regular layers. This can be changed manually.
