React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android. It’s based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms.

But in this tutorial we are going to convert our website's web view into app 😉

Step 1 : Installing Node JS

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Go to nodejs.org and download and install the the latest stable version (LTS) in your computer. "nodejs package includes both node and npm"

Step 2 : Installing Expo

Expo is a framework and a platform for universal React applications. It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps from the same JavaScript/TypeScript codebase.

The quickest way to install expo is using NPM, just open your terminal and write

npm install --global expo-cli

Step 3 : Initialising our app

Open your terminal and write

expo init

. This will generate a simple one screen app using React Native.

Once your app is create, navigate to your app folder using

cd [your-app-name]

and run

 expo start

When you run expo start (or npm start), Expo CLI starts Metro Bundler, which is an HTTP server that compiles the JavaScript code of our app using Babel and serves it to the Expo app. It also pops up Expo Dev Tools, a graphical interface for Expo CLI.

On your phone, download and install Expo Go app, after installing open it and press "Scan QR Code" on the "Projects" tab of the Expo Go app and scan the QR code you see in the terminal or in Expo Dev Tools.

Step 3 : Converting our website to App

Open your terminal and install react-native-webview by running the command

expo install react-native-webview

Once it is done, open your app's folder in any code editor such as VS code and in

app.js

paste the following code and save it

import * as React from "react";
import { WebView } from "react-native-webview";

export default class App extends React.Component {
  render() {
    return (
      <WebView source={{ uri: {your-website-link} }} style={{ marginTop: 20 }} />
    );
  }
}
