<a href="https://wenliangdai.github.io/" target="_blank" title="Live Demo">Live demo</a>

## Features
- A ready-to-use web audio player for React.js
- Highly-customizable. You can change theme color, size, functions of this player as you want.
- Just one single component on the top to use (Almost no learning cost).

## Install
- npm: `npm install react-audioplayer --save`
- yarn: `yarn add react-audioplayer`

## Usage
A simple example below.
```js
import Audio from 'react-audioplayer';
// In your render() function:
<Audio
  width={600}
  height={400}
  autoPlay={true}
  playlist={somePlaylist}
/>
```

### Acceptable props
| prop name              | value type | default value           | isRequired   | explanation                    |
| ---------------------- | ---------- | ----------------------- | ------------ | ------------------------------ |
| width                  | number     | 400                     | no           | Width of the <Audio /> component (px) |
| height                 | number     | fullPlayer ? 300 : 52   | no           | Height of the <Audio /> component (px) |
| color                  | string     | "#212121"               | no           | Theme color of the player |
| autoPlay               | bool       | false                   | no           | Automatically playing when loaded |
| volumeOrientationDown  | bool       | false                   | no           | Make the volume bar head downwards (make it true if the player is positioned at the very top of your webpage) |
| fullPlayer             | bool       | false                   | no           | If true, shows song image given in the playlist. Otherwise just shows the basic player |
| comment                | bool       | false                   | no           | If true, enables comment function. When fullPlayer is false, this is forced to be false. You need to specify `onCommentSubmit` to handle user input |
| onCommentSubmit (text) | Function   | null                    | no           | When a user submits a new comment, this function will be invoked and the input content will be passed as an argument |
| playlist               | array      | null                    | yes          | An array of song information objects, see [below](#playlist) for details |
| style                  | object     | null                    | no           | A normal style object. For example, you can add border or boxShadow to the component. If you also set width or height here, it will override the one you set using width or height API |

#### playlist prop<a name="playlist"></a>
playlist is an array of songObj, where
```js
songObj = {
  name: string, // song name
  src: string, // song source address
  img: string, // (optional) song image source address
  comments: an commentObj array // (optional) comments to display of that song
}

commentObj = {
  time: number,
  content: string
}
```
`songObj.img` is required when `fullPlay = true`, `songObj.comments` is required when `comment = true`.

## Manually control the state of the player in code
To play/pause/skip-to-next/skip-to-previous the player in code, four event listeners are added inside the `<Audio />` component.

The name of these events are:
- `audio-play`
- `audio-pause`
- `audio-skip-to-next`
- `audio-skip-to-previous`

and a typical example:
```js
class App extends React.Component {
  someMethod() {
    // Some code ...
    // This code can only be able to execute when the audio component is already mounted
    ReactDOM.findDOMNode(this.audioComponent).dispatchEvent(new Event('audio-play'));
  }

  render() {
    return (
      <Audio
        width={600}
        height={300}
        playlist={playlist}
        
        // store a reference of the audio component
        ref={audioComponent => { this.audioComponent = audioComponent; }}
      />
    );
  }
}
```
As you can see in the example above, there are two steps:
  1. Store the audio component using ref
  2. Get the DOM node (ReactDOM.findDOMNode) and dispatch the event (dispatchEvent)

## TODO
  - Loading animation and optimisation

## Development
```bash
$ git clone https://github.com/wenliangdai/react-audioplayer.git
$ npm install
$ npm start
```
Then a localhost is open on port 8080.
