API

Render Props:

// Scroll to position (20, 500) in the browser window
import React, { Component } from "react";
import { ScrollTo } from "react-scroll-to";

export default class MyComponent extends Component {
  render() {
    return (
      <ScrollTo>
        {({ scroll }) => (
          <a onClick={() => scroll({ x: 20, y: 500 })}>Scroll to Bottom</a>
        )}
      </ScrollTo>
    );
  }
}

// Scroll to position (0, 500) within all provided <ScrollArea /> children
import React, { Component } from "react";
import { ScrollTo, ScrollArea } from "react-scroll-to";

export default class MyComponent extends Component {
  render() {
    return (
      <ScrollTo>
        {({ scroll }) => (
          <ScrollArea style={{ height: 1000 }}>
            <button onClick={() => scroll({ y: 500, smooth: true })}>
              Scroll within this container
            </button>
          </ScrollArea>
        )}
      </ScrollTo>
    );
  }
}

// Scroll to position (0, 500) within a specific <ScrollArea /> child
import React, { Component } from "react";
import { ScrollTo, ScrollArea } from "react-scroll-to";

export default class MyComponent extends Component {
  render() {
    return (
      <ScrollTo>
        {({ scroll }) => (
          <div>
            <ScrollArea id="foo" style={{ height: 1000 }}>
              <button onClick={() => scroll({ id: "foo", y: 500 })}>
                Scroll within this container
              </button>
            </ScrollArea>

            <ScrollArea style={{ height: 1000 }}>
              This container won't scroll
            </ScrollArea>
          </div>
        )}
      </ScrollTo>
    );
  }
}

// Scroll by a component's ref
import React, { Component } from "react";
import { ScrollTo } from "react-scroll-to";

export default class MyComponent extends Component {
  myRef = React.createRef();

  render() {
    return (
      <>
        <ScrollTo>
          {({ scroll }) => (
            <a onClick={() => scroll({ ref: this.myRef, x: 20, y: 500 })}>
              Scroll to Bottom
            </a>
          )}
        </ScrollTo>

        <div ref={this.myRef}>My Element</div>
      </>
    );
  }
}

Higher Order Component:

// Scroll to position (0, 500) within the browser window
import React from "react";
import { ScrollToHOC } from "react-scroll-to";

export default ScrollToHOC(function(props) {
  return <a onClick={() => props.scroll({ y: 500 })}>Scroll to Bottom</a>;
});

// Scroll to position (0, 500) within all provided <ScrollArea /> children
import React from "react";
import { ScrollToHOC, ScrollArea } from "react-scroll-to";

export default ScrollToHOC(function(props) {
  return (
    <ScrollArea style={{ height: 1000 }}>
      <a onClick={() => props.scroll({ y: 500 })}>Scroll to Bottom</a>
    </ScrollArea>
  );
});

// Scroll to position (0, 500) within a specific <ScrollArea /> child
import React from "react";
import { ScrollToHOC, ScrollArea } from "react-scroll-to";

export default ScrollToHOC(function(props) {
  return (
    <div>
      <ScrollArea id="foo" style={{ height: 1000 }}>
        <a onClick={() => props.scroll({ id: "foo", y: 500 })}>
          Scroll to Bottom
        </a>
      </ScrollArea>

      <ScrollArea style={{ height: 1000 }}>
        This container won't scroll
      </ScrollArea>
    </div>
  );
});

Types:

• Typescript definitions are built in
• Flow is currently not support (Open for PRs!)

2.0 Changes

• v2.0 has a new API for controlling scrolling. Instead of taking two arguments, x and y, the ScrollTo component now takes an object.

scrollTo({
  x: 25 // The horizontal x position to scroll to
  y: 10 // The vertical y position to scroll to
  id: "myId" // The ID of the ScrollArea we want to scroll
  ref: refObj // A reference to a component to scroll
  smooth: true // If true, this will animate the scroll to be smooth. False will give an instant scroll. (defaults: false)
})

Mixing and matching these options give different results.

• The scrollById function has been deprecated in favor of the id field in scrollTo

Smooth Scrolling Not Working?

Some browsers don't natively support smooth scroll. Checkout adding a polyfill like smoothscroll-polyfill to fix the issue.

npm install smoothscroll-polyfill
