Quick Start

Several options to get up and running:

Clone the repo: git clone https://github.com/BobbyLH/roar
Install with npm: npm install roarjs
Install with Yarn: yarn add roarjs

In the browser:

<script src='pathTo/dist/roar.js' ></script>
<script>
    const Roar = window.Roar.default
    var sound = new Roar({
      playlist: ['sound.mp3']
    });
</script>

Examples

Most basic:

var sound = new Roar({
  playlist: ['sound.mp3', 'sound2.mp3'],
  autocut: true
});

sound.play();

More options:

var sound = new Roar({
  playlist: [
    {src: 'sound1.mp3', tag: 'your tag'}, 
    {src: 'sound2.mp3', tag: 'your tag'}
  ],
  // pick second playlist item for initiation
  initIndex: 1,
  autocut: (currentId, nextId) => {
    // handle async
    return new Promise((resovle, reject) => {
      // do something, such as http(s) request
      resovle(true)
    })
  }
  volume: 1,
  playModel: 'list-once',
  preload: true,
  loop: true,
  autoPlay: true,
  onload: e => {
    console.log('loading')
  },
  oncanplay: e => {
    console.log('can play')
    sound.play()
  },
  onplay: e => {
    console.log('playing')
  },
  onpause: e => {
    console.log('paused')
  },
  onstop: id => {
    console.log('stopped')
  },
  onend: e => {
    console.log('ended')
  },
  onseeking: e => {
    console.log('seeking')
  }
});

Listen for events:

var sound = new Roar({
  playlist: ['sound.mp3']
});

// Clear listener after first call onload event.
sound.once('load', function(){
  console.log('loading')
});

// Fires when the sound finishes playing.
sound.on('end', function(){
  console.log('ended!');
});

ES6:

import Roar from 'roarjs';

// or const Roar = require('roarjs').default

// or const { Roar } = require('roarjs')

// Setup the new Roar.
const sound = new Roar({
  playlist: ['sound.mp3']
});

// load the sound.
sound.load();

// Play the sound.
sound.play();

// Change the volume.
sound.volume(0.5)
