@ianbalijawa16/real-time-sync v1.0.1

@ianbalijawa16/real-time-sync 🔄

A lightweight, type-safe WebSocket-based real-time data synchronization library for TypeScript.

🚀 Features

• Effortless Real-Time Synchronization
• Strong TypeScript Type Safety
• Automatic Reconnection
• Flexible Conflict Resolution
• Minimal Dependencies

📦 Installation

npm install @ianbalijawa16/real-time-sync

💡 Basic Usage

import { RealTimeSync } from '@ianbalijawa16/real-time-sync';

interface UserData {
  id: number;
  name: string;
}

const sync = new RealTimeSync<UserData>('ws://localhost:8080', {
  reconnectAttempts: 3,
  conflictResolution: 'client-wins'
});

sync.subscribe('users', (userData) => {
  console.log('Received user data:', userData);
});

sync.publish('users', { id: 1, name: 'John Doe' });

sync.onConnect = () => console.log('Connected to server');
sync.onDisconnect = () => console.log('Disconnected from server');
sync.onError = (error) => console.error('Connection error:', error);

🛠 Configuration Options

Constructor Options

• url: WebSocket server URL
• reconnectAttempts: Maximum number of reconnection attempts (default: 5)
• reconnectDelay: Initial delay between reconnection attempts (default: 1000ms)
• conflictResolution: Data conflict resolution strategy

Conflict Resolution Strategies

1. 'client-wins': Client data takes precedence
2. 'server-wins': Server data takes precedence
3. Custom merge function: Define your own resolution logic

const sync = new RealTimeSync<UserData>(url, {
  conflictResolution: (clientData, serverData) => {
    // Custom merge logic
    return { ...serverData, ...clientData };
  }
});

🔌 API Methods

• subscribe(stream: string, callback): Listen to a specific data stream
• publish(stream: string, data): Send data to a stream
• unsubscribe(stream: string): Stop listening to a stream
• disconnect(): Close the WebSocket connection

🔒 Lifecycle Hooks

• onConnect: Triggered when connection is established
• onDisconnect: Triggered when connection is lost
• onError: Triggered on connection errors

📋 Requirements

• TypeScript 4.x+
• Modern browsers with WebSocket support
