[silenteyesoncode]

Description 🚀

This task enables real-time communication between multiple users in an Expo app using Socket.IO broadcast by establishing a socket connection, emitting and receiving events, and broadcasting messages to all connected clients on the server.

Socket

To Reproduce ✅

This is a task that outlines the steps to add Socket broadcast for cross-user transmission with Expo app as a client. By following these steps, you will be creating a new React Native project with Expo, installing and using the Socket.IO client library, establishing a socket connection to the server, emitting and receiving events, adding event handlers to handle incoming messages, and broadcasting messages to all connected clients on the server. This task aims to enable real-time communication between multiple users in an Expo app using Socket.IO broadcast.

Task✅

Objective

To enable real-time communication between multiple users in an Expo app using Socket.IO broadcast.

Prerequisites

• Node.js and npm installed
• Basic knowledge of React Native and Expo
• Basic knowledge of Socket.IO

Steps

1. Create a new React Native project with Expo using the following command:

   expo init my-app
   

2. Install the Socket.IO client for React Native using the following command:

   npm install socket.io-client
   

3. Create a new component called Chat in your project.

4. In the Chat component, import the Socket.IO client library using the following code:

   import io from 'socket.io-client';

5. In the Chat component, create a new socket connection to the server using the following code:

   const socket = io('http://localhost:3000');

   Note: Change the URL to the URL of your Socket.IO server.

6. Use the socket object to emit and receive events. For example, to send a message to all connected clients, use the following code:

   socket.emit('message', 'Hello, world!');

7. To receive messages from other clients, use the following code:

   socket.on('message', (data) => {
     console.log(data);
   });

8. Add event handlers to your Chat component to handle incoming messages and send messages to other clients.

9. On the server side, add the following code to broadcast messages to all connected clients:

   io.on('connection', (socket) => {
     socket.on('message', (data) => {
       io.emit('message', data);
     });
   });

10. Test your app by running it on multiple devices or emulators and sending messages between them.
