mui-scroll-trigger

Simple and convienent scroll-based transitions for React apps using MUI v5.

This component turns this:

import useScrollTrigger from '@mui/material/useScrollTrigger';
import Grow from '@mui/material/Grow

function HideOnScroll(props) {
  const { children } = props;

  const trigger = useScrollTrigger({ threshold: 400 });

  return (
    <Grow in={!trigger}>
      {children}
    </Grow>
  );
}

export default function App() {
  return (
    <HideOnScroll>
      <div>Hello</div>
    </HideOnScroll>
  )
}

Into this:

import ScrollTrigger from 'mui-scroll-trigger'

export default function App() {
  return (
    <ScrollTrigger threshold={400}>
      <div>Hello</div>
    </ScrollTrigger>
  )
}

...but with more options.

Want to use a different transition? The transition prop accepts any of the MUI v5 transitions as lowercase strings.

<ScrollTrigger transition="zoom">
  <div>Zoomed Hello</div>
</ScrollTrigger>

You can control whether the child element will transition in or out once the threshold is met with the onScroll prop. It accepts either "hide" or "show" and defaults to "hide".

<ScrollTrigger onScroll="show">
  <div>I will appear once the scroll threshold is met</div>
</ScrollTrigger>

You can conditionally disable the transition (ie. when a modal is open) and preserve it's current state with the disabled prop.

<ScrollTrigger disabled={someCondition}>
  <div>I will not transition while `someCondition` is true</div>
</ScrollTrigger>

Props

Name	Type	Default	Description
children*	node		What shall be transitioned... required
disabled	bool	false	Whether or not to disable the transition.
disableHysteresis	bool	false	Ignore the scroll direction when determining whether to apply the transition.
onScroll	string	'hide'	Whether to 'show' or 'hide' (transition in or out) at the scroll threshold.
target	node	window	Target to base scroll distance on. You normally won't need to adjust this.
threshold	number	100	Apply the chosen transition when the vertical scroll strictly crosses this threshold (exclusive).
transition	string	'grow'	MUI transition to apply at the threshold. Accepts one of 'slide', 'grow', 'zoom', 'collapse' or 'fade'.

* required prop

Any other props (eg. easing, timeout) will be passed directly to the chosen MUI transition component. This means you can also use any of the props of the Transition component from react-transition-group.

The disableHysteresis, target and threshold props work just like in the MUI useScrollTrigger hook.
