}); ws.on('error', error => { console.error(`WebSocket error for client ${clientId}:`, error); handleDisconnect(clientId); }); // Send a ping every HEARTBEAT_INTERVAL to keep the connection alive ws.isAlive = true; ws.on('pong', () => { ws.isAlive = true; }); }); // Heartbeat to check for dead connections setInterval(() => { wss.clients.forEach(ws => { if (ws.isAlive === false) { console.log("Terminating connection due to inactivity."); return ws.terminate(); } ws.isAlive = false; ws.ping(() => {}); }); }, HEARTBEAT_INTERVAL); console.log(`WebSocket server started on port ${PORT}`); ``` **Explanation and Key Improvements:** * **Dependencies:** Uses the `ws` package for WebSocket functionality. You'll need to install it: `npm install ws` * **Configuration:** `PORT` and `HEARTBEAT_INTERVAL` are configurable at the top. * **Data Structures:** * `clients`: A `Map` that stores client IDs as keys and their corresponding WebSocket objects as values. This allows you to easily look up a client's WebSocket connection by its ID. * `rooms`: A `Map` that stores room IDs as keys and `Set`s of client IDs as values. Using a `Set` ensures that each client ID appears only once in a room. * **`generateId()`:** A simple function to generate unique client and room IDs. **Important:** For production, use a more robust UUID generation library (e.g., `uuid`). The current implementation is sufficient for basic testing but is not guaranteed to be collision-free in a high-volume environment. * **`sendMessage(clientId, message)`:** A helper function to send a JSON-stringified message to a specific client. Includes error handling to catch potential issues during sending. Also checks if the client is still connected before attempting to send. * **`broadcastToRoom(roomId, message, excludeClientId)`:** A helper function to send a JSON-stringified message to all clients in a room, optionally excluding a specific client. * **`handleDisconnect(clientId)`:** Handles client disconnections gracefully. It removes the client from the `clients` map and from any rooms they were in. It also notifies other clients in the room that the client has left. Critically, it also removes empty rooms. * **WebSocket Server (`wss`)**: * **`connection` event:** Handles new WebSocket connections. * Generates a unique client ID. * Stores the client's WebSocket object in the `clients` map. * Sends the client their ID. * Sets up message handling, close handling, and error handling for the client. * **`message` event:** Handles incoming messages from clients. * Parses the message as JSON. * Uses a `switch` statement to handle different message types: * `createRoom`: Creates a new room and adds the client to it. * `joinRoom`: Adds the client to an existing room. * `leaveRoom`: Removes the client from a room. * `message`: Broadcasts a message to all other clients in the room. * `ping`: Responds to a ping message (for heartbeat). * Includes error handling for JSON parsing and unknown message types. * **`close` event:** Handles client disconnections. * **`error` event:** Handles WebSocket errors. * **Heartbeat (Ping/Pong):** Implements a heartbeat mechanism to detect and close dead connections. This is crucial for maintaining a stable connection with clients, especially in environments with unreliable networks. * A `setInterval` function sends a `ping` message to each client every `HEARTBEAT_INTERVAL`. * The `ws.isAlive` flag is set to `false` before sending the ping. * If the client responds with a `pong` message, the `ws.isAlive` flag is set back to `true`. * If the client doesn't respond within the interval, the connection is terminated. * **Error Handling:** Includes `try...catch` blocks to handle potential errors during message parsing and sending. Also logs errors to the console for debugging. * **Clear Logging:** Logs important events to the console, such as client connections, disconnections, room creation, joining, and leaving. * **Message Types:** Uses a consistent message format with a `type` field to identify the type of message. This makes it easier to handle different types of messages on both the server and the client. **How to Run:** 1. **Save:** Save the code as a `.js` file (e.g., `linkup_server.js`). 2. **Install `ws`:** `npm install ws` 3. **Run:** `node linkup_server.js` **Client-Side Example (Conceptual):** ```javascript // Client-side JavaScript (Conceptual - adapt to your framework) const ws = new WebSocket('ws://localhost:8080'); ws.onopen = () => { console.log('Connected to WebSocket server'); }; ws.onmessage = event => { const message = JSON.parse(event.data); console.log('Received message:', message); switch (message.type) { case 'clientId': console.log('My client ID is:', message.clientId); myClientId = message.clientId; // Store the client ID break; // Handle other message types (roomCreated, roomJoined, message, etc.) } }; ws.onclose = () => { console.log('Disconnected from WebSocket server'); }; ws.onerror = error => { console.error('WebSocket error:', error); }; function sendMessage(type, data) { ws.send(JSON.stringify({ type: type, ...data })); } // Example usage: // To create a room: // sendMessage('createRoom'); // To join a room: // sendMessage('joinRoom', { roomId: 'someRoomId' }); // To send a message to a room: // sendMessage('message', { roomId: 'someRoomId', content: 'Hello, everyone!' }); ``` **Important Considerations for Production:** * **Security:** * **HTTPS:** Use HTTPS (WSS) to encrypt the WebSocket connection. This is essential for protecting sensitive data. * **Authentication:** Implement authentication to verify the identity of clients. This can be done using various methods, such as JWTs or OAuth. * **Authorization:** Implement authorization to control what clients are allowed to do. For example, you might want to restrict access to certain rooms or features based on the client's role. * **Input Validation:** Validate all input from clients to prevent injection attacks. * **Scalability:** * **Load Balancing:** Use a load balancer to distribute traffic across multiple server instances. * **Horizontal Scaling:** Design the server to be horizontally scalable, so you can easily add more instances as needed. * **Message Broker:** Consider using a message broker (e.g., RabbitMQ, Kafka) to handle message distribution, especially if you need to support a large number of concurrent connections. * **Reliability:** * **Monitoring:** Implement monitoring to track the health and performance of the server. * **Logging:** Log all important events to a file or database for debugging and auditing. * **Error Handling:** Implement robust error handling to prevent crashes and ensure that the server can recover from errors gracefully. * **Heartbeats:** The heartbeat mechanism is crucial for detecting and closing dead connections. * **UUIDs:** Use a proper UUID library for generating unique IDs. * **Frameworks:** Consider using a WebSocket framework like Socket.IO or Primus. These frameworks provide higher-level abstractions and features that can simplify development and improve performance. However, for a basic MCP server, the `ws` library is often sufficient. This improved version provides a more robust and complete foundation for building a Linkup MCP server in JavaScript. Remember to adapt the code to your specific needs and requirements. Good luck!
