This repository is a Go language-based transformation of the original smallchat by antirez. We present a simple yet powerful chat server written in Go, leveraging the concurrency and network libraries of Go to provide a robust chat service that handles multiple clients over TCP connections.
- Multi-client support using TCP connections.
- Nickname setting for clients with the
/nickcommand. - Broadcast messages to all connected clients.
- Max client limitation to prevent overloading the server.
- Graceful handling of client disconnection.
Before you can run this server, you need to have Go installed on your system. You can download and install Go from the official site.
To start using this chat server, you need to clone this repository to your local machine. You can do this by running the following command:
git clone https://github.com/yaocanwei/smallchat.gitAfter cloning the repository, navigate to the directory where the repository is located and build the server using the Go build command:
go buildTo run the server, simply execute the built binary:
./mainThe server will start and listen for incoming TCP connections on port 7712.
To connect a client to the server, use any TCP client, such as netcat or telnet:
telnet localhost 7712Once connected, you can set your nickname using the /nick command followed by your desired nickname:
/nick YourNickname
After setting a nickname, any text you type will be sent to all connected clients.
The server uses a concurrent design where each client connection is handled in a separate goroutine. This allows for scalability and responsive client handling.
ChatSystemstruct - Holds the core chat logic, including observer management and message broadcasting.Clientstruct - Represents a connected client and is responsible for sending and receiving messages.
main.go- The entry point of the server that initializes the chat system and listens for client connections.
Feel free to fork and extend the functionality of this chat server. You can add new features like private messaging, chat rooms, and user authentication as needed.
