Let’s harness the power of React Native by learning “How to build a mobile app with React Native“. React native is like any other Native app, letting you build mobile app development using the JavaScript library. It uses the same design as React, which involves building a rich mobile UI that is the same as regular iOS and Android Apps.

With React-Native one can build a real mobile or cross-platform web application that is completely indistinguishable from the app built using Objective-C or Java.

React-Native uses fundamental UI blocks to create native apps for iOS and Android Applications. React Native uses “RCTBridgeModule” to make a connection between Native code and JavaScript Code.

One React – Many Platforms:

Using React – Single code can be shared across multiple platforms and use common technology.

import React from ‘react’;

import {Text, View} from ‘react-native’;

import {Header} from ‘./Header’;

import {heading} from ‘./Typography’;

const WelcomeScreen = () => (


    <Header title=”Welcome to React Native”/>

    <Text style={heading}>Step One</Text>


      Edit App.js to change this screen and turn it into your app.


    <Text style={heading}>See Your Changes</Text>


      Press Cmd + R inside the simulator to reload your app’s code.


    <Text style={heading}>Debug</Text>


      Press Cmd + M or Shake your device to open the React Native Debug Menu.
