redux-audio

Redux bindings for HTML5 audio elements

Installation

npm install redux-audio

Usage

In your root reducer:

import { audioReducer as audio } from 'redux-audio'
import { combineReducers } from 'redux'

export default combineReducers({ audio })

In your view component:

import React from 'react'
import { Audio } from 'redux-audio'

export default () => (
  <div>
    <Audio src='example.mp3' autoPlay uniqueId='example' controls loop />
    <p>Hello world.</p>
  </div>
)

Audio Container Component

The Audio container component wraps an HTML5 audio element, exposing it to Redux actions and bindings. It has the following props:

autoPlay

Boolean. When true, the audio track will play when the component mounts. Defaults to false.

controls

Boolean. When true, the audio element will expose its controls for playing. Defaults to false.

loop

Boolean. When true, the track will loop playback. Defaults to false.

preload

String. Possible values are ['none', 'metadata', 'auto']. Defaults to 'metadata'.

src

String. The source of the audio track. Defaults to ''.

uniqueId

String. Required. A unique identifier for the component. Must be unique with respect to other currently mounted Audio components.

Redux Store

The reducer provided attaches a single object to the main store object via the audio property. This object is an instance of immutable's Map class. Each Audio component's state is accessible by calling state.audio.get('uniqueId') where uniqueId corresponds to the uniqueId prop passed to the Audio component. Audio components' state objects are added when the component is mounted and removed when the component unmounts. Each Audio component's state is represented further by another Map object. This Map has the following keys:

command

Corresponds to strings representing the method last called for the audio element. When command is updated, the corresponding method is called. Possible values are ['play', 'pause', 'none'].

state

Corresponds to the current state of the audio element. Possible values are ['playing', 'paused', 'ended', 'none'].

src

Corresponds to the current value for src passed to the Audio element. When the value is updated, the src prop for the Audio component is updated.

Action Creators

All actions can be imported by import { actionName } from 'redux-audio/actions', where actionName is the action you wish to import.

audioPlay

Takes the uniqueId value of the component you want to play as an argument. Plays the audio track.

audioPause

Takes the uniqueId value of the component you want to pause as an argument. Pauses the audio track.

audioSrc

Takes two arguments. The first is the uniqueId value of the component you want to update. The second is the value you want the src prop to be updated to. Updates the src for the corresponding Audio component.
