React Native - CameraRoll

In this chapter, we will show you how to use Camera.

Step 1 − Home

In this step, we will create the src/components/home/Home.js file.


import React from 'react'
import CameraExample from './CameraExample.js'

const Home = () ⇒ {
   return (
      <CameraExample />
export default Home

Step 2 - Install Camera

The Camera module we want to use in this example is external so we need to install it first. We can do it from the terminal.

npm i react-native-camera@0.6

Step 2 – Permissions

If you use IOS 10, you need to add permissions in ios/reactTutorialApp/Info.plist.

<string>Your message to user when the camera is accessed for the first time</string>

Step 3 - Camera

takePicture method will return a promise and path of the picture.


import React, { Component } from 'react';

import {
from 'react-native';
import Camera from 'react-native-camera';

class Inputs extends Component {
   takePicture = () ⇒ {
      const options = {};{ metadata: options })
      .then((data) ⇒ console.log(data))
      .catch(err ⇒ console.error(err));
   render() {
      return (
         <View style = {styles.container}>
               ref = {(cam) ⇒ {
         = cam;
               style = {styles.preview}
               aspect = {Camera.constants.Aspect.fill}>
            <Text style = {styles.capture} onPress = {this.takePicture}>CAPTURE</Text>
export default Inputs

const styles = StyleSheet.create({
   container: {
      flex: 1,
   preview: {
      flex: 1,
      justifyContent: 'flex-end',
      alignItems: 'center'
   capture: {
      fontSize: 30,
      color: 'red',
      alignSelf: 'center',

When the app is run, it seeks permission as shown in the following screenshot.

NOTE − To be able to test the Camera on IOS, you must use mobile device since it won't work on a simulator.
