@zilahir/react-record-webcam

Webcam video and audio recording hook and component for React. Use hook for newer React versions, component uses classes so all React versions are supported. Works in all latest browser versions, although Safari requires MediaRecorder to be enabled in the experimental features.

Demo

Install dependency

yarn add react-record-webcam

Hook

import { useRecordWebcam } from 'react-record-webcam'

function RecordVideo(props) {
  const recordWebcam = useRecordWebcam();
  return (
    <div>
      <p>Camera status: {recordWebcam.status}</p>
      <button onClick={recordWebcam.open}>Open camera</button>
      <button onClick={recordWebcam.start}>Start recording</button>
      <button onClick={recordWebcam.stop}>Stop recording</button>
      <button onClick={recordWebcam.retake}>Retake recording</button>
      <button onClick={recordWebcam.download}>Download recording</button>
      <video ref={recordWebcam.webcamRef} autoPlay muted />
      <video ref={recordWebcam.previewRef} autoPlay muted loop />
    </div>
  )
}

Import the hook and initialize it in your function. The hook returns refs for both preview and recording video elements, functions to control recording (open, start, stop, retake, download) and camera status.

import { useRecordWebcam, CAMERA_STATUS } from 'react-record-webcam'

You can also import the CAMERA_STATUS constant to check for different states and toggle your UI accordingly. Check the CodeSandbox demo for a more thorough example on how to do this.

Passing options:

const OPTIONS = { ... }

const recordWebcam = useRecordWebcam(OPTIONS);

Option
downloadFileName?: string	Set a namespace for the component CSS classes
recordingLength?: number	Length of recording in seconds
recordingLength: number	Set max recording length in seconds
namespace: string	Pass own CSS namespace
options: RecorderOptions	Options for recording video
	`type: video
	`mimeType: video/mp4
	video: { minWidth, minHeight, maxWidth, maxHeight, minAspectRatio }

Component

import { RecordWebcam } from 'react-record-webcam'

...

function RecordVideo(props) {
  return (
    <RecordWebcam />
  )
}

You can include the component as is and it will render controls, video and preview elements. Alternatively you can use the render prop for more control:

function RecordVideo(props) {
  return (
    <RecordWebcam
      render={(props: WebcamRenderProps) => {
        return (
          <div>
            <h1>Component render prop demo</h1>
            <p>Camera status: {props.status}</p>
            <div>
              <button onClick={props.openCamera}>Open camera</button>
              <button onClick={props.retake}>Retake</button>
              <button onClick={props.start}>Start recording</button>
              <button onClick={props.stop}>Stop recording</button>
              <button onClick={props.download}>Download</button>
            </div>
          </div>
        );
      }}
    />
  )
}
