A React.js wrapper for howler.js (audio player)
npm install react-howler-ffA React.js wrapper for howler.js (audio player).
ReactHowler has no UI, you have to provide your own UI.
Props can be passed to control playback and react to events such as end, load, play, ...
howler.js is an audio library for the modern web. It defaults to Web Audio API and falls back to HTML5 Audio.
npm install --save react-howler
``javascript
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 (
playing={true}
/>
)
}
}
`
For a full working example please see it in App.js
http://khoanguyen.me/react-howler/
or
`shell`
git clone http://github.com/thangngoc89/react-howler
npm install
npm run example:react
open http://localhost:3000
Prop | Default | Description
---- | ------- | -----------
src | | The sources to the track(s) to be loaded for the sound (URLs or base64 data URIs). These should be in order of preference, howler.js will automatically load the first one that is compatible with the current browser. If your files have no extensions, you will need to explicitly specify the extension using the format property. src
Updating the prop on the fly will destroy any currently playing howler instance and create a new one with the new src. Updating other props while keeping the src the same will maintain the current howler instance.true
preload | true | Set to to begin downloading the audio file if it is not loaded yet.true
playing | true | Set to or false to pause or play the media.true
Setting to on initial load will play the audio immediately after it is loadedtrue
loop | false | Set to or false to enable/disable looptrue
mute | false | Set to or false to mute/unmute current audio0.0
volume | 1.0 | The volume of the specific howl, from to 1.0
html5 | false | Set to to force HTML5 Audio. This should be used for large audio files so that you don't have to wait for the full file to be downloaded and decoded before playing.
format | [] | howler.js automatically detects your file format from the extension, but you may also specify a format in situations where extraction won't work (such as with a SoundCloud stream).
onPlay | noop | Called when audio starts or resumes playing
onPause | noop | Called when audio is paused
onVolume | noop | Called when volume is changed
onStop | noop | Called when audio is stopped
onLoad | noop | Called when audio is loaded (buffered)
onLoadError | noop | Called when an error occurs whilst attempting to load media
onEnd | noop | Called when media finishes playing
#### duration([id])
Get the duration of the audio source. Will return 0 until after the load event fires.Number
* id: optional The sound ID to check. Passing an ID will return the duration of the sprite being played on this instance; otherwise, the full source duration is returned.
#### load()
When preload is true this is automatically called. When setting preload to false, you can call load() manually before playing sounds (useful for lazy loading large files on slow networks). If you attempt to play a sound that's not loading or loaded with preload react-howler will automatically call load().
Tip: If you're calling load() manually, check the load status with howlerState()
#### seek([seek])
Get/set the position of playback for a sound.
* seek: Number optional The position to move current playback to (in seconds).
#### howlerState()
Check the load status of the Howl, returns a string unloaded, loading or loaded.
This is an alias for Howler's state() function
#### stop([id])
Stops playback of sound, resetting seek to 0.Number
* id: optional The sound ID. If none is passed, all sounds in group are stopped.
#### Other howler.js methods
If you need to use other howler.js methods
that are not included in this wrapper you can access the howler instance directly via howler
`javascript
import React, { Component } from 'react'
import ReactHowler from 'react-howler'
class App extends Component {
getHower () {
this.player.howler
}
getDuration () {
this.player.duration()
}
getSeek () {
this.player.seek()
}
setSeek () {
this.player.seek(0.5)
}
// This sound file may not work due to cross-origin setting
render () {
return(
playing={true}
ref={(ref) => (this.player = ref)}
/>
);
}
}
`
Howler global methods are avaiable in window scope.
Please refer to howler's documentation
Usage:
`js`
window.Howler.mute(true) // Mute all sounds
This project uses standard code style.
