A simple React wrapper for the audio tag

# React Audio Player
This is a light React wrapper around the HTML5 audio tag.  It provides the ability to manipulate the player and listen to events through a nice React interface.

## Installation

    npm install --save react-audio-player

Also be sure you have `react` and `react-dom` installed in your app at version 15 or above.

## Usage

    import ReactAudioPlayer from 'react-audio-player';
    //...
    <ReactAudioPlayer
      src="my_audio_file.ogg"
      autoPlay
      controls
    />

### Example

See the example directory for a basic working example of using this project.  To run it locally, run `npm install` in the example directory and then `npm start`.

## Advanced Usage

### Access to the audio element
You can get direct access to the underlying audio element.  First get a ref to ReactAudioPlayer:

    <ReactAudioPlayer
      ref={(element) => { this.rap = element; }}
    />

Then you can access the audio element like this:

    this.rap.audioEl

This is especially useful if you need access to read-only attributes of the audio tag such as `buffered` and `played`.  See the [audio tag documentation](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/audio) for more on these attributes.
