What is react-scroll?

The react-scroll package provides smooth scrolling functionality for React applications. It allows developers to create scrollable components and implement smooth scrolling animations to specific elements within a page.

What are react-scroll's main functionalities?

Smooth Scrolling to Elements

This feature allows you to create links that smoothly scroll to specific elements on the page. The 'Link' component is used to create the scrollable link, and the 'Element' component is used to define the target section.

import { Link, Element } from 'react-scroll';

function App() {
  return (
    <div>
      <Link to="section1" smooth={true} duration={500}>Go to Section 1</Link>
      <Element name="section1" className="element">
        Section 1
      </Element>
    </div>
  );
}

Scroll Events

This feature allows you to register and handle scroll events. You can log or perform actions when scrolling begins or ends. The 'animateScroll' function can be used to programmatically scroll to specific positions.

import { Events, animateScroll as scroll, scroller } from 'react-scroll';

function App() {
  useEffect(() => {
    Events.scrollEvent.register('begin', function() {
      console.log('begin', arguments);
    });

    Events.scrollEvent.register('end', function() {
      console.log('end', arguments);
    });

    return () => {
      Events.scrollEvent.remove('begin');
      Events.scrollEvent.remove('end');
    };
  }, []);

  return (
    <div>
      <button onClick={() => scroll.scrollToTop()}>Scroll to Top</button>
    </div>
  );
}

Scroll to Top

This feature provides a simple way to scroll to the top of the page programmatically. The 'scrollToTop' function from 'animateScroll' is used to achieve this.

import { animateScroll as scroll } from 'react-scroll';

function App() {
  return (
    <div>
      <button onClick={() => scroll.scrollToTop()}>Scroll to Top</button>
    </div>
  );
}

Usage

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

var Link = Scroll.Link;
var Element = Scroll.Element;

var Events = Scroll.Events;

var Section = React.createClass({
  mixins: [Events],
  componentDidMount: function() {

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

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

  },
  componentWillUnmount: function() {
    this.scrollEvent.remove('begin');
    this.scrollEvent.remove('end');
  },
  render: function () {
  	return (
  		<Link to="test1" spy={true} smooth={true} offset={50} duration={500} >Test 1</Link>
		<Button className="btn" type="submit" value="Test 2" to="test2" spy={true} smooth={true} offset={50} duration={500} >Test 2</Button>

  		<Element name="test1" className="element">
  		  test 1
  		</Element>

  		<Element name="test2" className="element">
  		  test 2
  		</Element>
	);
  }
});

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

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');

Create your own Link/Element

Simply just include the mixins!

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

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

var Link = React.createClass({
  mixins: [Helpers.Scroll],
  render: function () {
    return (
      <a onClick={this.onClick}>
        {this.props.children}
      </a>
    );
  }
});
