GoLang IM System

This project is a simple Instant Messaging (IM) system implemented in Go. It consists of a server and a client, which can communicate with each other over the network.

Features

• Public chat: All users can send messages to a public chat room, and all messages in the public chat room can be seen by all users.
• Private chat: Users can send messages to a specific user privately.
• Online user list: Users can see a list of all online users.
• User rename: Users can change their username.

Usage

Server

To start the server, navigate to the server directory and build the server with the following command:

go build -o server server.go

Then, run the server with:

./server

Client

To start a client, navigate to the client directory and build the client with the following command:

go build -o client client.go

Then, run the client with:

./client

Once the client is running, follow the prompts in the terminal to chat publicly, chat privately, see the online user list, or change your username.

Note

This is a simple IM system for learning purposes. It does not implement many features that a full-fledged IM system would have, such as authentication, encryption, file transfer, voice chat, etc. Use it as a starting point for learning network programming with Go.
