Example

AUDIO/WAV

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

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>
