# Redux-Cluster-WS v2.0
[](https://www.npmjs.com/package/redux-cluster-ws)
[](https://www.npmjs.com/package/redux-cluster-ws)
[](https://www.npmjs.com/package/redux-cluster-ws)


Modern WebSocket-based state synchronization library built on top of [Redux-Cluster](https://github.com/siarheidudko/redux-cluster). Enables real-time Redux store synchronization between Node.js servers and clients (both Node.js and browser) using native WebSocket connections.
## โจ Features
- ๐ **Native WebSocket** - No Socket.IO dependency, better performance
- ๐ **Real-time sync** - Instant state synchronization across all clients
- ๐ **Universal** - Works in Node.js and browser environments
- ๐ฆ **Dual packaging** - Supports both ESM and CommonJS
- ๐ **Authentication** - Built-in login/password authentication
- ๏ฟฝ๏ธ **Security** - IP banning, connection limits, and validation
- ๐ **TypeScript** - Full TypeScript support with complete type definitions
- โก **Modern** - Built with ES2020+ features and modern best practices
## ๐๏ธ 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
## ๐ฆ Installation
```bash
npm install redux-cluster-ws redux
```
## ๐ Quick Start
### Server (Node.js)
```typescript
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)
```typescript
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
```html

Count: 0
+
-
// 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' });
}
```
## ๐ API Reference
### Server Configuration
```typescript
interface WSServerConfig {
port?: number; // Server port (default: 8080)
host?: string; // Server host (default: '0.0.0.0')
logins?: Record; // Login credentials
ips?: string[]; // Allowed IP addresses
bans?: string[]; // Banned IP addresses
limit?: number; // Connection limit
compression?: boolean; // Enable compression
origin?: string | string[]; // CORS origin
}
```
### Client Configuration
```typescript
interface WSClientConfig {
host?: string; // Server host (default: 'ws://localhost')
port?: number; // Server port (default: 8080)
login?: string; // Login username
password?: string; // Login password
reconnect?: boolean; // Auto-reconnect (default: true)
reconnectDelay?: number; // Reconnect delay ms (default: 1000)
timeout?: number; // Connection timeout ms (default: 5000)
}
```
### Methods
```typescript
// Server
store.createWSServer(config: WSServerConfig): void
// Client
store.createWSClient(config: WSClientConfig): void
// Both
store.dispatch(action: any): void
store.getState(): any
store.subscribe(listener: () => void): () => void
```
## ๐ง 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
```bash
# 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:
```typescript
// 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](./examples/README.md) for detailed usage instructions.
## ๐ 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
## ๐ Migration from v1.x
Redux-Cluster-WS v2.0 includes breaking changes from v1.x:
### Key Differences
| Feature | v1.x | v2.0 |
|---------|------|------|
| Protocol | Socket.IO | Native WebSocket |
| Language | JavaScript | TypeScript |
| Build | Single | Dual (ESM + CJS) |
| Dependencies | Many | Minimal |
| Browser Support | via CDN | UMD Bundle |
### Migration Steps
1. **Update imports**:
```typescript
// v1.x
const ReduxClusterWS = require('redux-cluster-ws');
// v2.0
import { createWSServer, createWSClient } from 'redux-cluster-ws';
```
2. **Update server creation**:
```typescript
// v1.x
store.setWebSocketServer({ port: 8080 });
// v2.0
store.createWSServer({ port: 8080 });
```
3. **Update client connection**:
```typescript
// v1.x
store.setWebSocketClient({ host: 'localhost', port: 8080 });
// v2.0
store.createWSClient({ host: 'ws://localhost', port: 8080 });
```
