README for react-in-viewport

React In Viewport

npm gzip size downloads

Library to detect whether or not a component is in the viewport, using the Intersection Observer API.

This library also uses MutationObserver to detect the change of the target element.

npm install --save react-in-viewport

yarn add react-in-viewport

Examples

Demo

Why

A common use case is to load an image when a component is in the viewport (lazy load).

We have traditionally needed to monitor scroll position and calculate the viewport size, which can be a scroll performance bottleneck.

Modern browsers now provide a new API--Intersection Observer API--which can make implementating this effort much easier and performant.

Polyfill

For browsers not supporting the API, you will need to load a polyfill. Browser support table

require('intersection-observer');

Design

The core logic is written using React Hooks. We provide two interfaces: you can use handleViewport, a higher order component (HOC) for class based components, or use hooks directly, for functional components.

The HOC acts as a wrapper and attaches the intersection observer to your target component. The HOC will then pass down extra props, indicating viewport information and executing a callback function when the component enters and leaves the viewport.

Usages

Using Higher Order Component

When wrapping your component with handleViewport HOC, you will receive inViewport props indicating whether the component is in the viewport or not.

handleViewport HOC accepts three params: handleViewport(Component, Options, Config)

ParamsTypeDescription
ComponentReact ElementCallback function for when the component enters the viewport
OptionsObjectOptions you want to pass to Intersection Observer API
ConfigObjectConfigs for HOC (see below)

Supported config

ParamsTypeDefaultDescription
disconnectOnLeavebooleanfalseDisconnect intersection observer after leave

HOC Component Props

PropsTypeDefaultDescription
onEnterViewportfunctionCallback function for when the component enters the viewport
onLeaveViewportfunctionCallback function for when the component leaves the viewport

The HOC preserves onEnterViewport and onLeaveViewport props as a callback

Props passed down by HOC to your component

PropsTypeDefaultDescription
inViewportbooleanfalseWhether your component is in the viewport
forwardedRefReact refAssign this prop as a ref on your component
enterCountnumberNumbers of times your component has entered the viewport
leaveCountnumberNumber of times your component has left the viewport

NOTE: Need to add ref={this.props.forwardedRef} to your component

Example of a functional component

import handleViewport, { type InjectedViewportProps } from 'react-in-viewport';

const Block = (props: InjectedViewportProps<HTMLDivElement>) => {
  const { inViewport, forwardedRef } = props;
  const color = inViewport ? '#217ac0' : '#ff9800';
  const text = inViewport ? 'In viewport' : 'Not in viewport';
  return (
    <div className="viewport-block" ref={forwardedRef}>
      <h3>{ text }</h3>
      <div style={{ width: '400px', height: '300px', background: color }} />
    </div>
  );
};

const ViewportBlock = handleViewport(Block, /** options: {}, config: {} **/);

const Component = (props) => (
  <div>
    <div style={{ height: '100vh' }}>
      <h2>Scroll down to make component in viewport</h2>
    </div>
    <ViewportBlock onEnterViewport={() => console.log('enter')} onLeaveViewport={() => console.log('leave')} />
  </div>
))

Example for enter/leave counts

  • If you need to know how many times the component has entered the viewport, use the prop enterCount.
  • If you need to know how many times the component has left the viewport, use the prop leaveCount.
import React, { Component } from 'react';
import handleViewport from 'react-in-viewport';

class MySectionBlock extends Component {
  getStyle() {
    const { inViewport, enterCount } = this.props;
    //Fade in only the first time we enter the viewport
    if (inViewport && enterCount === 1) {
      return { WebkitTransition: 'opacity 0.75s ease-in-out' };
    } else if (!inViewport && enterCount < 1) {
      return { WebkitTransition: 'none', opacity: '0' };
    } else {
      return {};
    }
  }

  render() {
    const { enterCount, leaveCount, forwardedRef } = this.props;
    return (
      <section ref={forwardedRef}>
        <div className="content" style={this.getStyle()}>
          <h1>Hello</h1>
          <p>{`Enter viewport: ${enterCount} times`}</p>
          <p>{`Leave viewport: ${leaveCount} times`}</p>
        </div>
      </section>
    );
  }
}
const MySection = handleViewport(MySectionBlock, { rootMargin: '-1.0px' });

export default MySection;

Using Hooks

Alternatively, you can also directly using useInViewport hook which takes similar configuration as HOC.

import React, { useRef } from 'react';
import { useInViewport } from 'react-in-viewport';

const MySectionBlock = () => {
  const myRef = useRef(null);
  const {
    inViewport,
    enterCount,
    leaveCount,
  } = useInViewport(
    myRef,
    options,
    config = { disconnectOnLeave: false },
    props
  );

  return (
    <section ref={myRef}>
      <div className="content" style={this.getStyle()}>
        <h1>Hello</h1>
        <p>{`Enter viewport: ${enterCount} times`}</p>
        <p>{`Leave viewport: ${leaveCount} times`}</p>
      </div>
    </section>
  );
};
