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

    });
  }

  stopRecording = () => {
    this.setState({

  }

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

Having issues with the lambda function?

Try installing babel-preset-stage-1

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

e.g.

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']
            }
        }]

    }
};
