Usage
import React, { useEffect } from 'react';
import { Link, Button, Element, Events, animateScroll as scroll, scrollSpy } from 'react-scroll';
const Section = () => {
// useEffect is used to perform side effects in functional components.
// Here, it's used to register scroll events and update scrollSpy when the component mounts.
useEffect(() => {
// Registering the 'begin' event and logging it to the console when triggered.
Events.scrollEvent.register('begin', (to, element) => {
console.log('begin', to, element);
});
// Registering the 'end' event and logging it to the console when triggered.
Events.scrollEvent.register('end', (to, element) => {
console.log('end', to, element);
});
// Updating scrollSpy when the component mounts.
scrollSpy.update();
// Returning a cleanup function to remove the registered events when the component unmounts.
return () => {
Events.scrollEvent.remove('begin');
Events.scrollEvent.remove('end');
};
}, []);
// Defining functions to perform different types of scrolling.
const scrollToTop = () => {
scroll.scrollToTop();
};
const scrollToBottom = () => {
scroll.scrollToBottom();
};
const scrollTo = () => {
scroll.scrollTo(100); // Scrolling to 100px from the top of the page.
};
const scrollMore = () => {
scroll.scrollMore(100); // Scrolling an additional 100px from the current scroll position.
};
// Function to handle the activation of a link.
const handleSetActive = (to) => {
console.log(to);
};
// Rendering the component's JSX.

Scroll Methods
Scroll To Top
import { animateScroll } from 'react-scroll';
const options = {
// your options here, for example:
duration: 500,
smooth: true,
};
animateScroll.scrollToTop(options);
Scroll To Bottom
import { animateScroll } from 'react-scroll';
const options = {
// Your options here, for example:
duration: 500,
smooth: true,
};
animateScroll.scrollToBottom(options);
Scroll To (position)
import { animateScroll } from 'react-scroll';
const options = {
// Your options here, for example:
duration: 500,
smooth: true,
};
// Scroll to 100 pixels from the top of the page
animateScroll.scrollTo(100, options);
Scroll To (Element)
animateScroll.scrollTo(positionInPixels, props = {});
import { Element, scroller } from 'react-scroll';
<Element name="myScrollToElement"></Element>
// Somewhere else, even another file
scroller.scrollTo('myScrollToElement', {
duration: 1500,
delay: 100,
smooth: true,
containerId: 'ContainerElementID',
offset: 50, // Scrolls to element + 50 pixels down the page
// ... other options
});
Scroll More (px)
import { animateScroll } from 'react-scroll';
const options = {
// Your options here, for example:
duration: 500,
smooth: true,
};
// Scroll an additional 10 pixels down from the current scroll position
animateScroll.scrollMore(10, options);
Scroll events
begin - start of the scrolling
import { Events } from 'react-scroll';
Events.scrollEvent.register('begin', function(to, element) {
console.log('begin', to, element);
});
end - end of the scrolling/animation
import { Events } from 'react-scroll';
Events.scrollEvent.register('end', function(to, element) {
console.log('end', to, element);
});
Remove events
import { Events } from 'react-scroll';
Events.scrollEvent.remove('begin');
Events.scrollEvent.remove('end');
Create your own Link/Element
Simply just pass your component to one of the high order components (Element/Scroll)
import React from 'react';
import { ScrollElement, ScrollLink } from 'react-scroll';
const Element = (props) => {
return (
<div {...props} ref={(el) => { props.parentBindings.domNode = el; }}>
{props.children}
</div>
);
};
export const ScrollableElement = ScrollElement(Element);
const Link = (props) => {
return (
<a {...props}>
{props.children}
</a>
);
};
export const ScrollableLink = ScrollLink(Link);
Scroll Animations
Add a custom easing animation to the smooth option. This prop will accept a Boolean if you want the default, or any of the animations listed below
import { scroller } from 'react-scroll';
scroller.scrollTo('myScrollToElement', {
duration: 1500,
delay: 100,
smooth: 'easeInOutQuint',
containerId: 'ContainerElementID',
// ... other options
});
List of currently available animations:
linear
- no easing, no acceleration.
easeInQuad
- accelerating from zero velocity.
easeOutQuad
- decelerating to zero velocity.
easeInOutQuad
- acceleration until halfway, then deceleration.
easeInCubic
- accelerating from zero velocity.
easeOutCubic
- decelerating to zero velocity.
easeInOutCubic
- acceleration until halfway, then deceleration.
easeInQuart
- accelerating from zero velocity.
easeOutQuart
- decelerating to zero velocity.
easeInOutQuart
- acceleration until halfway, then deceleration.
easeInQuint
- accelerating from zero velocity.
easeOutQuint
- decelerating to zero velocity.
easeInOutQuint
- acceleration until halfway, then deceleration.
