react-howler

react-howler

A React.js wrapper for howler.js (audio player).

ReactHowler has no UI. You has to provide your own UI

Props can be passed to control playback and react to events such as end, load, play, ...

howler.js

howler.js is an audio library for the modern web. It defaults to Web Audio API and falls back to HTML5 Audio.

Usage

npm install --save react-howler

import React, { Component } from 'react'
import ReactHowler from 'react-howler'

class App extends Component {
  // This sound file may not work due to cross-origin setting
  render () {
    return (
      <ReactHowler
        src='http://goldfirestudios.com/proj/howlerjs/sound.ogg'
        playing={true}
      />
    )
  }
}

For a full working example please see it in App.js

import ReactHowler from 'react-howler'

class App extends Component {
  getHower () {
    this.audio.howler
  }

  getDuration () {
    this.audio.duration()
  }

  getSeek () {
    this.audio.seek()
  }

  setSeek () {
    this.audio.seek(0.5)
  }
  // This sound file may not work due to cross-origin setting
  render () {
    return(
      <ReactHowler
        src='http://goldfirestudios.com/proj/howlerjs/sound.ogg'
        playing={true}
        ref={(ref) => this.audio = ref}
