Redux-Cluster-WS v2.0

GitHub last commit GitHub release

Modern WebSocket-based state synchronization library built on top of Redux-Cluster. Enables real-time Redux store synchronization between Node.js servers and clients (both Node.js and browser) using native WebSocket connections.

✨ Features

🚀 Native WebSocket - No Socket.IO dependency, better performance
🔄 Real-time sync - Instant state synchronization across all clients
🌐 Universal - Works in Node.js and browser environments
📦 Dual packaging - Supports both ESM and CommonJS
🔒 Authentication - Built-in login/password authentication
�️ Security - IP banning, connection limits, and validation
📝 TypeScript - Full TypeScript support with complete type definitions
⚡ Modern - Built with ES2020+ features and modern best practices

🏗️ Architecture

Redux-Cluster-WS v2.0 represents a complete architectural modernization:

WebSocket Protocol: Native WebSocket replacing Socket.IO for better performance
TypeScript First: Complete rewrite in TypeScript with strict typing
Modern Build System: Dual ESM/CommonJS builds with proper type declarations
Simplified Dependencies: Minimal dependency tree for better security and performance
Universal Design: Single codebase works in Node.js and browsers

📦 Installation

npm install redux-cluster-ws redux

🚀 Quick Start

Server (Node.js)

import { ReduxCluster } from 'redux-cluster';
import { createWSServer } from 'redux-cluster-ws';

// Create your Redux reducer
function counterReducer(state = { count: 0 }, action: any) {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    case 'DECREMENT':
      return { count: state.count - 1 };
    default:
      return state;
  }
}

// Create Redux-Cluster store
const store = new ReduxCluster(counterReducer);

// Start WebSocket server
store.createWSServer({
  port: 8080,
  logins: {
    'admin': 'password123',
    'user': 'secret456'
  }
});

console.log('WebSocket server started on ws://localhost:8080');

Client (Node.js)

import { ReduxCluster } from 'redux-cluster';
import { createWSClient } from 'redux-cluster-ws';

// Same reducer as server
function counterReducer(state = { count: 0 }, action: any) {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    case 'DECREMENT':
      return { count: state.count - 1 };
    default:
      return state;
  }
}

// Create client store
const store = new ReduxCluster(counterReducer);

// Connect to server
store.createWSClient({
  host: 'ws://localhost',
  port: 8080,
  login: 'admin',
  password: 'password123'
});

// Listen to state changes
store.subscribe(() => {
  console.log('State:', store.getState());
});

// Dispatch actions
store.dispatch({ type: 'INCREMENT' });

Browser Client

</head>
<body>
  <div id="counter">Count: 0</div>

  <button onclick="decrement()">-</button>

  <script>
    // Create store with reducer
    const store = new ReduxCluster.ReduxCluster((state = { count: 0 }, action) => {
      switch (action.type) {
        case 'INCREMENT':
          return { count: state.count + 1 };
        case 'DECREMENT':
          return { count: state.count - 1 };
        default:
          return state;
      }
    });

    // Connect to WebSocket server
    store.createWSClient({
      host: 'ws://localhost',
      port: 8080,
      login: 'admin',
      password: 'password123'
    });

    // Update UI on state change
    store.subscribe(() => {
      document.getElementById('counter').textContent = 
        `Count: ${store.getState().count}`;
    });

    // Action dispatchers
    function increment() {
      store.dispatch({ type: 'INCREMENT' });
    }

    function decrement() {
      store.dispatch({ type: 'DECREMENT' });
    }

🔧 Examples

The /examples directory contains comprehensive examples:

server.js - Complete WebSocket server with authentication
client.js - Interactive command-line client
browser.html - Web browser client with UI
cross-library-server.js - Hybrid server (IPC + WebSocket)
cross-library-client.js - Node.js client for hybrid setup
cross-library-browser.html - Browser client for hybrid setup

# Run the examples
cd examples
node server.js     # Start server
node client.js     # Start client (in another terminal)

Cross-Library Integration

Redux-Cluster-WS v2.0 can work seamlessly with Redux-Cluster for hybrid architectures:

// Hybrid server - uses both IPC and WebSocket
import { ReduxCluster } from 'redux-cluster';
import { createWSServer } from 'redux-cluster-ws';

const store = createStore(reducer);

// Setup redux-cluster for IPC/TCP (worker processes)
const cluster = new ReduxCluster(store, {
  worker: { count: 4, file: './worker.js' }
});

// Setup WebSocket server for web clients
createWSServer({
  port: 8080,
  store,
  auth: { login: 'web', password: 'secret' }
});

// Now both worker processes (via IPC) and web clients (via WebSocket)
// share the same Redux store state in real-time!

This hybrid approach allows:

Backend processes to communicate via fast IPC/TCP
Frontend clients to connect via WebSocket
Real-time synchronization across all participants
Optimal performance for each use case

See examples/README.md for detailed usage instructions.

🔒 Security Features

Authentication: Login/password based user authentication
IP Filtering: Allow/deny specific IP addresses
Connection Limits: Limit concurrent connections
Input Validation: Validate all incoming messages
Auto-banning: Automatic IP banning for failed authentication

// v2.0
import { createWSServer, createWSClient } from 'redux-cluster-ws';

Update server creation:

// v1.x
store.setWebSocketServer({ port: 8080 });
   
// v2.0
store.createWSServer({ port: 8080 });

Update client connection:

// v1.x
store.setWebSocketClient({ host: 'localhost', port: 8080 });
   
// v2.0
store.createWSClient({ host: 'ws://localhost', port: 8080 });
