ParallaxProvider

The <ParallaxProvider /> component is meant to wrap a root level component in your application and is necessary to provide access through the React context API to the Parallax Controller.

import { ParallaxProvider } from 'react-scroll-parallax';

Examples​

This component should only be used once in your app, for instance in an <AppContainer /> component that won't be mounted/unmounted during route changes. Like so:

const AppContainer = () => (
  <ParallaxProvider>
    <Router>
      <App />
    </Router>
  </ParallaxProvider>
);
info

You can have multiple providers, however they will all be independent instances of a ParallaxController. It's recommended to only use one when possible.

Props​

The following props configure the <ParallaxProvider> component:

NameTypeDefaultDescription
scrollAxisstringverticalOptionally pass the scroll axis for setting horizontal/vertical scrolling. One of vertical or horizontal
scrollContainerHTMLElement<body>Optionally set the container that has overflow and will contain parallax elements. Defaults to the document scroll body.
isDisabledbooleanfalseDisables the ParallaxController and all animations.

More Examples​

Using props you can configure the provider for the following conditions.

Horizontal Scrolling​

If your app's overflow is horizontal, you'll need to change the scrollAxis:

const AppContainer = () => (
  <ParallaxProvider scrollAxis="horizontal">
    <Router>
      <App />
    </Router>
  </ParallaxProvider>
);

Scroll Container​

By default the <ParallaxProvider> uses the document scrolling element. If your app's overflow is a unique element you need to provide the element as the scrollContainer.

Here's how you can do that using React hooks to set a ref to a DOM element. The useEffect will be called once after mounting then update state with the element to be passed to the provider.

ScrollContainer.tsx
import * as React from 'react';
import { ParallaxProvider } from 'react-scroll-parallax';

const ScrollContainer = () => {
  const [scrollEl, setScrollElement] = React.useState<HTMLDivElement>(null);
  const ref = React.useRef<HTMLDivElement>();
  React.useEffect(() => {
    setScrollElement(ref.current);
  });

  return (
    <div className="your-scroll-container" ref={ref}>
      <ParallaxProvider scrollContainer={scrollEl}>
        {props.children}
      </ParallaxProvider>
    </div>
  );
};

Disabling All Parallax Elements​

With the isDisabled prop you may disable every parallax element in the provider when a condition is met, instead of individually. This can be helpful to disable parallax in certain situations like on mobile devices, or for users who prefers-reduced-motion. Elements will be re-enabled when isDisabled is true.

const App = () => {
  const userPrefersReducedMotion = useMediaQuery({
    query: '(prefers-reduced-motion)',
  });

  return (
    <ParallaxProvider isDisabled={userPrefersReducedMotion}>
      {props.children}
    </ParallaxProvider>
  );
};
