react-html5-camera-photo-patched v1.5.12

react-html5-camera-photo

The first objective of this package comes from the need to get the same look and feel of a native mobile camera app but with a react component. For those who want to build with their own css and need an abstraction of getUserMedia() take a look of jslib-html5-camera-photo with react.

Requirement

• react: >=16.8.0
• react-dom: >=16.8.0

LiveDemo

Demo of react-html5-camera-photo

Required Working Environment for getUserMedia()

• https or localhost : The getUserMedia() method is only available in secure contexts (https or localhost). If a document isn't loaded in a secure context, the navigator.mediaDevices property is undefined, making access to getUserMedia() impossible. Attempting to access getUserMedia() in this situation will result in a TypeError. See developer.mozilla.org

• iOS >= 11 WebRTC issue with webkit (Chrome & Firefox) : Apple restricts WebRTC to Safari only so it mean that you can't use the getUserMedia() with Firefox and Chrome. So getUserMedia() is not supported yet, for "security reasons". See Stackoverflow

Installation

npm install --save react-html5-camera-photo

yarn add react-html5-camera-photo

TypeScript Definitions

TypeScript definitions are available from Definitely Typed

Getting started

Minimum ES6 example

import React from 'react';
import Camera from 'react-html5-camera-photo';
import 'react-html5-camera-photo/build/css/index.css';

function App (props) {
  function handleTakePhoto (dataUri) {
    // Do stuff with the photo...
    console.log('takePhoto');
  }

  return (
    <Camera
      onTakePhoto = { (dataUri) => { handleTakePhoto(dataUri); } }
    />
  );
}

export default App;

API

PropTypes

Dynamic : If the prop is dynamic, it mean that you can change that prop dynamically without umount the component (removing it). You can do it by a setState() inside the parent component. Checkout the demo example: ./src/demo/AppWithDynamicProperties.js

Example of closing the camera and image preview after take a photo

Probably the typical usage of using this component is to preview the image and close the camera after take a photo. You can take a look of all the code including the ImagePreview component here : ./src/demo/AppWithImagePreview

import React, { useState } from 'react';
import Camera from 'react-html5-camera-photo';
import 'react-html5-camera-photo/build/css/index.css';

import ImagePreview from './ImagePreview'; // source code : ./src/demo/AppWithImagePreview/ImagePreview

function App (props) {
  const [dataUri, setDataUri] = useState('');

  function handleTakePhotoAnimationDone (dataUri) {
    console.log('takePhoto');
    setDataUri(dataUri);
  }

  const isFullscreen = false;
  return (
    <div>
      {
        (dataUri)
          ? <ImagePreview dataUri={dataUri}
            isFullscreen={isFullscreen}
          />
          : <Camera onTakePhotoAnimationDone = {handleTakePhotoAnimationDone}
            isFullscreen={isFullscreen}
          />
      }
    </div>
  );
}

export default App;

Example with all props used

import React from 'react';
import Camera, { FACING_MODES, IMAGE_TYPES } from 'react-html5-camera-photo';
import 'react-html5-camera-photo/build/css/index.css';

function App (props) {
  function handleTakePhoto (dataUri) {
    // Do stuff with the photo...
    console.log('takePhoto');
  }

  function handleTakePhotoAnimationDone (dataUri) {
    // Do stuff with the photo...
    console.log('takePhoto');
  }

  function handleCameraError (error) {
    console.log('handleCameraError', error);
  }

  function handleCameraStart (stream) {
    console.log('handleCameraStart');
  }

  function handleCameraStop () {
    console.log('handleCameraStop');
  }

  return (
    <Camera
      onTakePhoto = { (dataUri) => { handleTakePhoto(dataUri); } }
      onTakePhotoAnimationDone = { (dataUri) => { handleTakePhotoAnimationDone(dataUri); } }
      onCameraError = { (error) => { handleCameraError(error); } }
      idealFacingMode = {FACING_MODES.ENVIRONMENT}
      idealResolution = {{width: 640, height: 480}}
      imageType = {IMAGE_TYPES.JPG}
      imageCompression = {0.97}
      isMaxResolution = {true}
      isImageMirror = {false}
      isSilentMode = {false}
      isDisplayStartCameraError = {true}
      isFullscreen = {false}
      sizeFactor = {1}
      onCameraStart = { (stream) => { handleCameraStart(stream); } }
      onCameraStop = { () => { handleCameraStop(); } }
    />
  );
}

export default App;

Bug report (issues)

Before sending a bug report of camera error, make sure that getUserMedia() is supported by your browser. Please test your camera on : DetectRTC | Is WebRTC Supported In Your Browser? If the System has Webcam is supported, please send the screenshot of the first 7 first rows of the table.
