Join me as we delve into the seas of code and learn how to effortlessly check and respond to internet connections in React Native.

Let's embark on this coding voyage together! 🚢🌐

Here's a step-by-step guide on how to check internet connection in a React Native app:

Firstly, make sure you have the necessary package installed. Run the following command in your project directory

npm install @react-native-community/netinfo

Import the NetInfo module in the file where you want to check the internet connection. Typically, this would be in your component or screen file.

// YourComponent.js
import NetInfo from '@react-native-community/netinfo';

Now, you can use the NetInfo module to check the internet connection. Here's a simple example:

// YourComponent.js
import React, { useEffect, useState } from 'react';
import { View, Text } from 'react-native';
import NetInfo from '@react-native-community/netinfo';

const YourComponent = () => {
  const [isConnected, setIsConnected] = useState(true);

  useEffect(() => {
    const unsubscribe = NetInfo.addEventListener(state => {
      setIsConnected(state.isConnected);
    });

    return () => {
      unsubscribe();
    };
  }, []);

  return (
    <View>
      <Text>
        {isConnected
          ? 'You are connected to the internet'
          : 'Oops! No internet connection'}
      </Text>
    </View>
  );
};

export default YourComponent;

Integrate your YourComponent in the main file (e.g., App.js).

// App.js
import React from 'react';
import YourComponent from './YourComponent';

const App = () => {
  return <YourComponent />;
};

export default App;

Save the files and run your app using:

npx react-native run-android

or

npx react-native run-ios

Open your app on a device or emulator, and you should see a message indicating whether you are connected to the internet or not.

And there you have it! A simple and effective way to check the internet connection in a React Native app.
