react-media-recorder :o2: :video_camera: :microphone:

react-media-recorder is a react component with render prop that can be used to record audio/video streams using MediaRecorder API.

Installation

npm i -S react-media-recorder  

or

yarn add react-media-recorder  

Usage

import ReactMediaRecorder from "react-media-recorder";

const RecordView = () => (
  <div>
    <ReactMediaRecorder
      video
      render={({ status, startRecording, stopRecording, mediaBlob }) => (
        <div>
          <p>{status}</p>
          <button onClick={startRecording}>Start Recording</button>
          <button onClick={stopRecording}>Stop Recording</button>
          <video src={mediaBlob} controls />
        </div>
      )}
    />
  </div>
);

Since react-media-recording uses render prop, you can define what to render in the view. Just don't forget to wire the startRecording, stopRecording and mediaBlob to your component.

Props available in the render function

status

A string enum. Possible values:

• idle
• recording
• paused
• stopped
• no_constraints
• invalid_media_constraints
• no_specified_media_found
• media_in_use
• media_aborted
• permission_denied
• delayed_start (only if a delay has been set) [deprecating soon]

If the audio is muted, you'll see the status suffixed with _muted.

startRecording

A function, which starts recording when invoked.

pauseRecording

A function, which pauses the recording when invoked.

resumeRecording

A function, which resumes the recording when invoked.

stopRecording

A function, which stops recording when invoked.

muteAudio

A function, which mutes the audio tracks when invoked.

unmuteAudio

A function which unmutes the audio tracks when invoked.

mediaBlob

A blob url that can be wired to an <audio />, <video /> or an <a /> element.

Options / Props

audio

Can be either a boolean value or a MediaTrackConstraints object.

type: boolean or object
default: true

blobPropertyBag

From MDN:
An optional BlobPropertyBag dictionary which may specify the following two attributes (for the mediaBlob):

• type, that represents the MIME type of the content of the array that will be put in the blob.
• endings, with a default value of "transparent", that specifies how strings containing the line ending character \n are to be written out. It is one of the two values: "native", meaning that line ending characters are changed to match host OS filesystem convention, or "transparent", meaning that endings are stored in the blob without change

type: object
default:
if video is enabled,

{
   type: "video/mp4"
}

if there's only audio is enabled,

{
  type: "audio/wav"
}

delay [deprecating soon]

If you want to start recording after a delay. In milliseconds.

type: number
default: 0

muted [deprcating soon]

Whether you want to mute the audio (while recording video)

type: boolean
default: false

render

A function which accepts an object containing fields: status, startRecording, stopRecording andmediaBlob. This function would return a react element/component.

type: function
default: () => null

video

Can be either a boolean value or a MediaTrackConstraints object.

type: boolean or object
default: false

whenStopped(blobUrl)

Will be invoked when the recording stops. This callback will be invoked with the blobUrl as its params.

type: function
default: () => null
