TCPChat is a simple group chat implementation using a Server-Client architecture. It allows multiple clients to connect to a central server and exchange messages in a group chat format. The server handles incoming connections, manages client messages, and broadcasts messages to all connected clients.
- TCP connection between the server and multiple clients (one-to-many).
- Clients are required to provide a name.
- Control the maximum number of allowed connections (10 connections).
- Clients can send messages to the chat.
- Empty messages are not broadcasted.
- Messages are timestamped with the sender's name and time of sending.
- New clients receive previous chat history upon joining.
- Clients are notified when another client joins or leaves.
- All clients receive messages sent by other clients.
- Clients can disconnect without affecting other clients.
- Default port is 8989, but can be specified as a command line argument.
Compile the project:
go build -o tcpchat main.goRun the server:
./tcpchat [port]port(optional): The port number to listen on. If not provided, the default port is 8989 is used.
Clients can connect to the server using nc command:
nc localhost [port]Each client is prompted to enter a name. Once connected, clients can start sending messages to the chat.
To exit, simply close the client's terminal.
./tcpchat 8888nc localhost 8888Go version 1.20.1 Used only the standard library
