## Example 

# AUDIO/WAV

```js
import { ReactMic } from 'react-mic';

export class Example extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      record: false
    }

  }

  startRecording = () => {
    this.setState({
      record: true
    });
  }

  stopRecording = () => {
    this.setState({
      record: false
    });
  }

  onData(recordedBlob) {
    console.log('chunk of real-time data is: ', recordedBlob);
  }

  onStop(recordedBlob) {
    console.log('recordedBlob is: ', recordedBlob);
  }

  render() {
    return (
      <div>
        <ReactMic
          record={this.state.record}
          className="sound-wave"
          onStop={this.onStop}
          onData={this.onData}
          strokeColor="#000000"
          backgroundColor="#FF4081" />
        <button onTouchTap={this.startRecording} type="button">Start</button>
        <button onTouchTap={this.stopRecording} type="button">Stop</button>
      </div>
    );
  }
}
```

# AUDIO/MP3

```js
import { ReactMic } from 'react-mic';

export class Example extends React.Component {
  ...

  onData() {
    console.log('This function does not return an object, but is called at a time interval of 10ms');
  }

  onStop(recordedBlob) {
    console.log('recordedBlob is: ', recordedBlob);
  }

  render() {
    return (
      <div>
        <ReactMic
          record={this.state.record}
          className="sound-wave"
          onStop={this.onStop}
          onData={this.onData}
          strokeColor="#000000"
          backgroundColor="#FF4081" 
          mimeType="audio/mp3" />
        <button onTouchTap={this.startRecording} type="button">Start</button>
        <button onTouchTap={this.stopRecording} type="button">Stop</button>
      </div>
    );
  }
}

# Having issues with the lambda function?
Try installing babel-preset-stage-1

Include stage-1 in your webpack.config under presets.

e.g.

```js
module.exports = {
    entry: "./scripts/Main.js",
    output: {
        path: __dirname,
        filename: "./static/script.js"
    },
    module: {
        loaders: [{
            test: /\.css$/,
            loader: "style!css"
        }, {
            test: /\.js$/,
            // exclude: /(node_modules)/,
            loader: 'babel-loader',
            query: {
                presets: ['es2015', 'react', 'stage-1']
            }
        }]

    }
};
```
