react-native-sensors

Supported React Native Versions

Getting started

$ npm install react-native-sensors --save

Mostly automatic installation

$ react-native link react-native-sensors

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-sensors and add RNSensors.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNSensors.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import com.reactlibrary.RNSensorsPackage; to the imports at the top of the file
• Add new RNSensorsPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-sensors'
   project(':react-native-sensors').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-sensors/android')

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

   compile project(':react-native-sensors')

Usage

Sensor API

import { Accelerometer, Gyroscope } from 'react-native-sensors';
const accelerationObservable = new Accelerometer({
  updateInterval: 100, // defaults to 100ms
});

// Normal RxJS functions
accelerationObservable
  .map(({ x, y, z }) => x + y + z)
  .filter(speed => speed > 20)
  .subscribe(speed => console.log(`You moved your phone with ${speed}`));

setTimeout(() => {
  accelerationObservable.stop();
}, 1000);

Decorator usage

import React, { Component } from 'react';
import { Text, View } from 'react-native';
import { decorator as sensors } from 'react-native-sensors';

class MyComponent { // no lifecycle needed
  render() {
    const {
      Accelerometer,
      Gyroscope,
    } = this.props;

    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Acceleration has value: {Accelerometer}
          Gyro has value: {Gyroscope}
        </Text>
      </View>
    );
  }
}

export default sensors({
  Accelerometer: {
    updateInterval: 300, // optional
  },
  Gyroscope: true,
  Magnetometer: false, // disabled
})(MyComponent);

Credits

This project is inspired by the react-native-sensor-manager and by the react-native-motion-manager. Both have similar solutions with a non-uniform interface and this project aims to unify both.
