Migrating from RCTCamera to RNCamera

Project Integration

Please follow the RNCamera doc installation guide to install the face detection frameworks on both platforms.

iOS

Open your app's XCode project. Expand the Libraries folder in the project navigation and right click and delete the RCTCamera.xcodeproj.

On your project's target, on Build Phases, click on libRCTCamera.a and delete (press the - button below).

You can follow the installation steps for RNCamera on the readme to link the new RNCamera project to your app's XCode project.

You can do it via react-native link command or by the manual steps.

Before building and running again, do a complete clean on your project.

Android

  1. On the MainApplication of your Android project change the import of RCTCameraPackage line to:
import org.reactnative.camera.RNCameraPackage;
  1. Inside the getPackages() methods change new RCTCameraPackage() to new RNCameraPackage().

  2. On android/app/build.gradle, change the line: compile (project(':react-native-camera')) to:

compile (project(':react-native-camera')) {
  exclude group: "com.google.android.gms"
}
compile ("com.google.android.gms:play-services-vision:10.2.0") {
  force = true;
}
  1. Add jitpack to android/build.gradle
allprojects {
  repositories {
    maven { url "https://jitpack.io" }
  }
}

Usage differences

imports

Instead of importing Camera, now, you should import { RNCamera } from react-native-camera.

No captureMode prop

On RCTCamera, you would set the camera captureMode to still or video and you could only record or take a picture depending on the captureMode of your Camera.

On RNCamera you do not need to specify captureMode. The RNCamera, in any state, can record or take a picture calling the appropriate method.

capture to takePictureAsync or recordAsync

Let's say you have a component with a RCTCamera taking a photo:

import Camera from 'react-native-camera';

class TakePicture extends Component {

  takePicture = async () => {
    try {
      const data = await this.camera.capture();
      console.log('Path to image: ' + data.path);
    } catch (err) {
      // console.log('err: ', err);
    }
  };

  render() {
    return (
      <View style={styles.container}>
        <Camera
          ref={cam => {
            this.camera = cam;
          }}
          style={styles.preview}
          aspect={Camera.constants.Aspect.fill}
          captureAudio={false}
        >
          <View style={styles.captureContainer}>
            <TouchableOpacity style={styles.capture} onPress={this.takePicture}>
              <Icon style={styles.iconCamera}>camera</Icon>
              <Text>Take Photo</Text>
            </TouchableOpacity>
          </View>
        </Camera>

        <View style={styles.space} />
      </View>
    );
  }
}

You should change this to:

import { RNCamera } from 'react-native-camera';

class TakePicture extends Component {

  takePicture = async () => {
    try {
      const data = await this.camera.takePictureAsync();
      console.log('Path to image: ' + data.uri);
    } catch (err) {
      // console.log('err: ', err);
    }
  };

  render() {
    return (
      <View style={styles.container}>
        <RNCamera
          ref={cam => {
            this.camera = cam;
          }}
          style={styles.preview}
        >
          <View style={styles.captureContainer}>
            <TouchableOpacity style={styles.capture} onPress={this.takePicture}>
              <Icon style={styles.iconCamera}>camera</Icon>
              <Text>Take Photo</Text>
            </TouchableOpacity>
          </View>
        </RNCamera>

        <View style={styles.space} />
      </View>
    );
  }
}

The same logic applies to change capture to recordAsync.

flashMode and torchMode

In RCTCamera, there was flashMode and torchMode prop. In RNCamera, these are combined into the flashMode prop.

Other differences

Take a look into the RCTCamera doc and the RNCamera doc to see more differences.
