Chat Server

Overview

This project implements a simple chat server in Go, allowing multiple clients to connect and communicate with each other in real-time. Each client is assigned a name and can send messages that are broadcasted to all other connected clients.

Features

• Multiple client support: The server can handle multiple clients connecting and chatting simultaneously.
• Real-time broadcasting: Messages from clients are immediately broadcasted to all other connected clients.
• Graceful client disconnect: The server handles client disconnections gracefully and cleans up resources.

Project Structure

• Client: Represents a single client connection. Manages reading and writing messages to the client.
• Server: Manages client connections, broadcasting messages, and handling client registration and unregistration.
• main: The entry point of the application. Sets up the server and handles incoming client connections.

How It Works

1. Server Initialization: The server is initialized and starts listening for incoming TCP connections on port 8080.
2. Client Connection: When a new client connects, they are prompted to enter their name.
3. Message Handling:
   • The client's messages are read and broadcasted to all other connected clients.
   • Messages are formatted to include the client's name.
4. Client Registration and Unregistration:
   • Clients are registered when they connect and unregistered when they disconnect.
   • The server ensures proper cleanup of resources when a client disconnects.
