Recent Statistics on React Native App Development

React Native is a JavaScript framework that allows you to create native mobile apps. It's based on React, Facebook's JavaScript library for creating user interfaces, but instead of being aimed at browsers, it's aimed at mobile platforms.

In the past year, React Native has become one of the most popular frameworks for building native mobile apps. This is due in part to its ease of use and ability to create cross-platform apps.

According to a recent report from App Annie, React Native was the third most popular platform for developing new iOS applications in Q1 2019. It was also the fifth most popular platform for developing new Android applications in Q1 2019.

The popularity of React Native is also evident in GitHub's annual Octoverse report. In 2018, React Native was the 15th most popular repository on GitHub with over 24,000 stars. That placed it ahead of other popular repositories such as Vue.js and AngularJS.

With its popularity on the rise, there are sure to be more statistics released in the coming months about React Native app development.

What Is React Native?

React Native is a cross-platform mobile app development framework that lets you create native apps for Android and iOS using React. If you're a web developer looking to branch out into mobile app development, React Native is an excellent choice. It lets you use your existing knowledge of React to build native apps without having to learn a new language or framework.

React Native also has the advantage of being open source, so there's a large community of developers who are always working on improving it.

React Native Components

There are two types of components in React Native:

Functional components

Functional components are simple and easy to write. They are basically JavaScript functions that accept props and return JSX. We can use them for small, one-off pieces of UI, like buttons or simple presentational components.

Class-based components

Class-based components are more complex and allow us to use features like local state and lifecycle methods. They are usually used for larger pieces of UI, like forms or sections of our app.

Building a React Native App 

Assuming that you already have React Native installed on your system, we can now create a new project.


To do so, launch the terminal and type the following commands:

react-native init name_of_your_app

cd name_of_your_app

react-native run-ios

This will create a new React Native app with the given name and start it in the iOS simulator. You can also use 'react-native run-android' to start the app in the Android emulator. 

Step 2 

Now that the project is set up, we can start building our app.

The first thing we need to do is import the React Native components that we will be using. For this example, we will be using the 'View' and 'Text' components.

import React, { Component } from 'react';

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

Next, we need to create a class that extends the 'Component' class. This class will be responsible for rendering our app's UI.

class App extends Component {

  render() {

    return (

      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>

        <Text>Hello World!</Text>





export default App; 

We need to export our App class so that it can be used by other parts of our app.

Step 3

Now that we have our App class setup, we can use it to render our app's UI. To do this, we need to open the 'App.js' file and add the following code: 

import React, { Component } from 'react';

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

class App extends Component {

  render() {

    return (


        <Text>Hello World!</Text>





export default App; 

This code will render the 'Hello World!' text to the screen. If you run the app now, you should see the following output: 

Hello World!

Testing and Deploying Your App

Assuming you have followed all of the previous steps in this guide, you are now ready to test and deploy your app.

To test your app, you will need to run it on a physical device or an emulator. The process for doing this will vary depending on your platform (iOS or Android).

Once you have successfully tested your app on a physical device or an emulator, you are ready to deploy it. Deploying an app is different from testing an app because it makes the app available to the general public.

There are many ways to deploy a React Native app, but the most common method is to use Expo. Expo is a platform that allows you to create and publish React Native apps with ease.
