Implements real-time WebSocket communication with connection management, room-based messaging, and horizontal scaling. Use when building chat systems, live notifications, collaborative tools, or real-time dashboards.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WebSocket Implementation
Build scalable real-time communication systems with proper connection management.
## Server Implementation (Socket.IO)
```javascript
const { Server } = require('socket.io');
const { createAdapter } = require('@socket.io/redis-adapter');
const { createClient } = require('redis');
const io = new Server(server, {
cors: { origin: process.env.CLIENT_URL, credentials: true }
});
// Redis adapter for horizontal scaling
const pubClient = createClient({ url: process.env.REDIS_URL });
const subClient = pubClient.duplicate();
Promise.all([pubClient.connect(), subClient.connect()]).then(() => {
io.adapter(createAdapter(pubClient, subClient));
});
// Connection management
const users = new Map();
io.use((socket, next) => {
const token = socket.handshake.auth.token;
try {
socket.user = verifyToken(token);
next();
} catch (err) {
next(new Error('Authentication failed'));
}
});
io.on('connection', (socket) => {
users.set(socket.user.id, socket.id);
console.log(`User ${socket.user.id} connected`);
socket.on('join-room', (roomId) => {
socket.join(roomId);
socket.to(roomId).emit('user-joined', socket.user);
});

How to install
mdr add secondsky/claude-skills/websocket-implementation@sha256:085db660f6fe813fThe line at the top of this page pins the label git:20260402.75421fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
