WebSocket Server

This is an example of a WebSocket server written in Go. It utilizes the Gorilla WebSocket library to handle WebSocket connections.

Features

The server has the following features:

• Accepts WebSocket connections on the "/ws" route.
• Allows clients to connect and send messages.
• Maintains a list of connected clients.
• Broadcasts received messages from a client to all other connected clients.

Usage

1. Make sure you have Go installed on your system.

2. Download or clone this repository.

3. Open a terminal and navigate to the root directory of the project.

4. Run the following command to start the server:

   go run main.go

5. The server will be running on port 8080.

6. Open a web browser and access http://localhost:8080.

7. The web client will display a page with a text input field.

8. Open multiple browser tabs or windows to simulate multiple clients.

9. Type a message in the text box and press Enter.

10. The message will be sent to all other connected clients.

Project Structure

• The main.go file contains the main logic of the WebSocket server.
• The github.com/gorilla/websocket package is used to enhance the functionality of the net/http package.
• The HomeHandler function handles the initial route and serves the public/index.html file.
• The WsHandler function is called when a client connects to the "/ws" route.
• The AddClient function adds the client to the list of connected clients.
• The BroadcastMessageToAll function sends a message to all connected clients.
• The BroadcastMessageToClient function sends a message to a specific client.
• The BroadcastMessageToOthers function sends a message to all clients except the specific client.
• The HandleClientMessages function handles messages received from a client and broadcasts them to other clients.
• The CleanupClients function checks client connections and removes disconnected clients from the list.
• The MonitorClientConnections function periodically checks client connections.

Dependencies

This project depends on the Gorilla WebSocket library. You can install it using the following command:

go get github.com/gorilla/websocket

Make sure you have set up the Go environment correctly for the dependencies to be installed properly.

Conclusion

This is a simple example of a WebSocket server in Go. It allows multiple clients to connect and exchange real-time messages. Feel free to explore and modify the code to fit your specific needs.
