react-jw-player 🎥 Build Status

<ReactJWPlayer> is a React Component for initializing client-side instances of JW Player. Simply give <ReactJWPlayer> the id of your player script, and the id of a JW Player video or playlist. The component comes with several event hooks that can be accessed through component props.

Contents

Installation

npm install react-jw-player

Usage

At the mininum, you can just use something like the three following code snippets:

Playing a JW Player JSON Playlist

import React from 'react';
import ReactDOM from 'react-dom';
import ReactJWPlayer from 'react-jw-player';

ReactDOM.render(
  <ReactJWPlayer
    playerId='my-unique-id'
    playerScript='https://link-to-my-jw-player/script.js'
    playlist='https://link-to-my-playlist.json'
  />,
  document.getElementById('my-root-div');
);

Playing a custom Playlist

import React from 'react';
import ReactDOM from 'react-dom';
import ReactJWPlayer from 'react-jw-player';

const playlist = [{
  file: 'https://link-to-my-video.mp4',
  image: 'https://link-to-my-poster.jpg',
  tracks: [{
    file: 'https://link-to-subtitles.vtt',
    label: 'English',
    kind: 'captions',
    'default': true
  }],
},
{
  file: 'https://link-to-my-other-video.mp4',
  image: 'https://link-to-my-other-poster.jpg',
}];

ReactDOM.render(
  <ReactJWPlayer
    playerId='my-unique-id'
    playerScript='https://link-to-my-jw-player/script.js'
    playlist={playlist}
  />,
  document.getElementById('my-root-div');
);

Playing a Specific File

import React from 'react';
import ReactDOM from 'react-dom';
import ReactJWPlayer from 'react-jw-player';

ReactDOM.render(
  <ReactJWPlayer
    playerId='my-unique-id'
    playerScript='https://link-to-my-jw-player/script.js'
    file='https://link-to-my-video.mp4'
  />,
  document.getElementById('my-root-div');
);

For more complex interaction, check out the container component example here

To generate preroll, supply the player with the generatePrerollUrl prop. This prop just needs to be a function that returns a valid VAST tag! See (Optional Configuration Props)[#optional-configuration-props] for more info.

Required Props

These are props that modify the basic behavior of the component.

  • playerId
    • A unique Id for the player instance. Used to distinguish the container divs.
    • Type: string
    • Example: playerId="my-jw-player-instance"
  • playerScript
    • Link to a valid JW Player script.
    • Type: string
    • Example: https://content.jwplatform.com/libraries/abCD1234.js
  • playlist OR file
    • Link to a valid JW Player playlist or video file, or playlist array. Cool tip: JW Player automatically generates JSON feeds for individual videos if you use the video id in place of abCD1234. You can use this to get meta data on the videos without loading an actual playlist.
    • Type: string (for file and playlist) or array (for playlist)
    • Example: https//content.jwplatform.com/feeds/abCD1234.json

Optional Configuration Props

  • aspectRatio
    • An optional aspect ratio to give the video player. Can be 'inherit', 1:1 or 16:9 currently.
    • Defaults to 'inherit'.
  • className
    • An optional class name to give the container div.
    • Type: string
  • customProps
    • An optional object containing properties to be applied directly to the JW Player instance. Add anything in the API, like skins, into this object. customProps={{ skin: { name: 'six' } }}.
    • Type: object
  • isAutoPlay
    • Determines whether the player starts automatically or not.
    • Type: boolean
  • isMuted
    • Determines whether the player starts muted or not.
    • Type: boolean
  • generatePrerollUrl(video)
    • Supply a function that returns a VAST or GOOGIMA tag for use in generating a preroll advertisement.
    • Arguments:
      • video
        • This is a video object for the current item loaded in the player. You can use it to help generate your preroll tags.
  • image
    • URL to a poster image to display before playback starts
    • Type: string
  • licenseKey
    • License Key as supplied in the jwplayer dashboard, under: Players > Tools > Downloads > JW Player X (Self-Hosted)
    • Type: string
  • useMultiplePlayerScripts
    • EXPERIMENTAL - Allows you to load multiple player scripts and still load the proper configuration. Expect bugs, but report them!
    • Type: boolean

Event Hooks

react-jw-player dynamically supports all events in JW Player. Simply preface the event name with on and pass it in as a prop.

Example Container Component

import React from 'react';
import PropTypes from 'prop-types';

import ReactJWPlayer from 'react-jw-player';

const displayName = 'ReactJWPlayerContainer';

const propTypes = {
  playlist: PropTypes.string.isRequired,
  playerScript: PropTypes.string.isRequired
};

class ReactJWPlayerContainer extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      videoTitle: '',
    };

    this.onAdPlay = this.onAdPlay.bind(this);
    this.onReady = this.onReady.bind(this);
    this.onVideoLoad = this.onVideoLoad.bind(this);

    // each instance of <ReactJWPlayer> needs a unique id.
    // we randomly generate it here and assign to the container instance.
    this.playerId = someFunctionToRandomlyGenerateId();
  }
  onReady(event) {
    // interact with JW Player API here
    const player = window.jwplayer(this.playerId);
  }
  onAdPlay(event) {
    // track the ad play here
  }
  onVideoLoad(event) {
    this.setState({
      videoTitle: event.item.description // this only works with json feeds!
    });
  }
  render() {
    return (
      <div className='react-jw-player-container'>
        <h1>{ this.state.videoTitle }</h1>
        <ReactJWPlayer
          playlist={this.props.playlist}
          licenseKey='your-license-key'
          onAdPlay={this.onAdPlay}
          onReady={this.onReady}
          onVideoLoad={this.onVideoLoad}
          playerId={this.playerId} // bring in the randomly generated playerId
          playerScript='https://link-to-your-jw-player-script.js'
        />
      </div>
    );
  }

ReactJWPlayerContainer.propTypes = propTypes;
ReactJWPlayerContainer.defaultProps = defaultProps;
ReactJWPlayerContainer.displayName = displayName;
export default ReactJWPlayerContainer;
