Usage

// ES6 Imports
import * as Scroll from 'react-scroll';
import { Link, Element , Events, animateScroll as scroll, scrollSpy, scroller } from 'react-scroll'


// Or Access Link,Element,etc as follows
let Link       = Scroll.Link;
let Element    = Scroll.Element;
let Events     = Scroll.Events;
let scroll     = Scroll.animateScroll;
let scrollSpy  = Scroll.scrollSpy;

// ES5
var React   = require('react');
var Scroll  = require('react-scroll');

var Link       = Scroll.Link;
var Element    = Scroll.Element;
var Events     = Scroll.Events;
var scroll     = Scroll.animateScroll;
var scrollSpy  = Scroll.scrollSpy;


var Section = React.createClass({

    });

      console.log("end", arguments);
    });

    scrollSpy.update();

  },

    );

React.render(
  <Section />,
  document.getElementById('example')
);

Props/Options

activeClass - class applied when element is reached

to - target to scroll to

containerId - container to listen for scroll events and to perform scrolling in

spy - make Link selected when scroll is at its targets position

hashSpy - update hash based on spy, containerId has to be set to scroll a specific element.

smooth - animate the scrolling

offset - scroll additional px ( like padding )

duration - time of the scroll animation - can be a number or a function (function (scrollDistanceInPx) { return duration; }), that allows more granular control at run-time

delay - wait x milliseconds before scroll

isDynamic - in case the distance has to be recalculated - if you have content that expands etc.

onSetActive - invoke whenever link is being set to active

onSetInactive - invoke whenever link is lose the active status

ignoreCancelEvents - ignores events which cancel animated scrolling

<Link activeClass="active"
      to="target"
      spy={true}
      smooth={true}
      hashSpy={true}
      offset={50}
      duration={500}
      delay={1000}
      isDynamic={true}
      onSetActive={this.handleSetActive}
      onSetInactive={this.handleSetInactive}
      ignoreCancelEvents={false}
>
  Your name
</Link>

Scroll Methods

Scroll To Top


var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollToTop(options);

Scroll To Bottom


var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollToBottom(options);

Scroll To (position)


var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollTo(100, options);

Scroll To (Element)

animateScroll.scrollTo(positionInPixels, props = {});


var Scroll = require('react-scroll');
var Element = Scroll.Element;
var scroller = Scroll.scroller;

<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
  ...
})

Scroll More (px)


var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollMore(10, options);

Scroll events

begin - start of the scrolling


var Scroll = require('react-scroll');
var Events = Scroll.Events;

Events.scrollEvent.register('begin', function(to, element) {
  console.log("begin", to, element);
});

end - end of the scrolling/animation


Events.scrollEvent.register('end', function(to, element) {
  console.log("end", to, element);
});

Remove events


Events.scrollEvent.remove('begin');
Events.scrollEvent.remove('end');

Simply just pass your component to one of the high order components (Element/Scroll)

var React   = require('react');
var Scroll  = require('react-scroll');
var ScrollLink = Scroll.ScrollLink;
var ScrollElement = Scroll.ScrollElement;

var Element = React.createClass({
  render: function () {
    return (
      <div {...this.props}>
        {this.props.children}
      </div>
    );
  }
});

module.exports = ScrollElement(Element);

var Link = React.createClass({
  render: function () {
    return (
      <a {...this.props}>
        {this.props.children}
      </a>
    );
  }
});

module.exports = 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


scroller.scrollTo('myScrollToElement', {
  duration: 1500,
  delay: 100,
  smooth: "easeInOutQuint",
  containerId: 'ContainerElementID',
  ...
})

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.
