Connecting to Socket in React Native app

Connecting to a socket in a React Native app requires the use of a socket library that supports React Native. One popular library is socket.io-client.

Here are the steps to connect to a socket using socket.io-client in a React Native app:

1. Install socket.io-client by running the following command in your project directory:

npm install socket.io-client

2. Import the library in your code:

import io from 'socket.io-client';

3. Create a socket instance by calling the io function and passing in the URL of the socket server:

const socket = io('http://example.com');

Replace http://example.com with the URL of your socket server.

4. Add event listeners to the socket instance to handle incoming events:

    socket.on('connect', () => {
      console.log('Connected to socket server');
    });
    socket.on('event', (data) => {
      console.log('Received data:', data);
    });
  

Replace event with the name of the event you want to listen for.

5. Emit events to the socket server using the emit method:

socket.emit('event', { data: 'Hello, world!' });

Replace event with the name of the event you want to emit.

That's it! You should now be able to connect to a socket in your React Native app and receive and send data.
