Getting Started With React Native

Step 1: Install Node.JS
URL: NodeJS Download  


Step 2: Install Expo CLI

npm install --global expo-cli

Ref: https://expo.dev/tools

Step 3: Install Expo Client on Your Phone

Ref: https://expo.dev/client



Step 4: Initialize a blank Expo project

(base) E:\Workspace\react_native>expo init msg_tracker
√ Choose a template: » blank               a minimal app as clean as an empty canvas
√ Downloaded and extracted project files.
📦 Using npm to install packages.
√ Installed JavaScript dependencies.

✅ Your project is ready!

To run your project, navigate to the directory and run one of the following npm commands.

- cd msg_tracker
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web

                5 Dir(s)  579,593,072,640 bytes free


(base) E:\Workspace\react_native\msg_tracker>type App.js
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';

export default function App() {
  return ( 
    <View style={styles.container}>
        <Text>Open up App.js to start working on your app!</Text>
        <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
    container: {
      flex: 1,
      backgroundColor: '#fff',
      alignItems: 'center',
      justifyContent: 'center',
    },
});


Step 5: Starting the application with "$ expo start"
Before running "expo start", make sure that your Desktop and Phone are on same WiFi network, in my case it is Airtel-MyWiFi.
