Introduction to The Current Technology – React Native

Introduction to The Current Technology – React Native includes the basic definition and the main concept behind the origin of the React Native. Let’s get started.

Introduction to The Current Technology – React Native

React Native is a JavaScript Framework which is used to build native mobile apps using JavaScript and React. It uses the same design as React and maintained by Facebook and a community of individual developers and companies.

Like, React it lets you compose complex UIs from small and isolated pieces of code called “components”. It is currently one of the most popular JavaScript frameworks.

React Native is very useful to build Android and IOS Apps.

Why React Native?

One thing that should come in our mind is that Cross-platform frameworks like Cordova, PhoneGap, IONIC, and more were already in the industry to build Hybrid apps then why React Native?

To answer this just think what if you could create Cross-Platform Native Mobile Apps using the single JavaScript framework? Amazing Right?

This is the beauty of React Native. With React Native, you don’t build a “mobile web app”, an “HTML5 app”, or a “hybrid app”. You build a real mobile app that’s indistinguishable from an app built using Objective-C or Java.

It uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.

Native Code Integration

You can also add your Native components in React Native which are written in Objective-C, Java, or Swift. It lets you integrate your already written code in React Native and you can further develop the application using React Native.

If you want to optimize a few aspects of your application you can write those sections in Native code and can integrate with React Native App easily. It’s also easy to build part of your app in React Native, and part of your app using the native code directly. Facebook application is the best example of this.

React Native is a component-based language and everything in React Native is a component. For example, one could make a <SocialPost > component that would display a Post heading, Image, Description, comments, the user can submit the comment etc — all just by including one line of code: <SocialPost ></SocialPost>.

The biggest advantage of using components is that you can change any component at any point in time without affecting the rest of the applications. This feature is most effective when implemented with larger applications where data changes frequently.

When we update or change any data, React Native automatically updates the specific component whose state has actually changed. This saves from the task of reloading the whole application to reflect the changes.

Example of the Single Screen with Text using React Native is

import React from 'react';
import { Text, View } from 'react-native';

export default App = () => {
  render() {
    return (
      <View>
        <Text>
          React Native is Awesome 
        </Text>
      </View>
    );
  }
}

We hope we were able to explain what is React Native and why you should use it to develop the Mobile Applications.
