📦 Installation

npm install @typeorm/sync-adapter

🎯 Quick Start

import { createSyncAdapter } from '@typeorm/sync-adapter';

const syncAdapter = createSyncAdapter({
  database: 'sqlite',
  syncInterval: 5000,
  enableCompression: true,
});

// Start synchronization
await syncAdapter.start();

🏗️ Architecture

The framework is organized into several key modules:

@typeorm/sync-adapter/
├── core/           # Main synchronization engine
├── client/         # Browser and mobile client libraries  
├── admin/          # Database administration UI
├── migrations/     # Schema management system
└── services/       # Business logic and utilities

🎯 Use Cases

Offline-First Applications

import { SyncClient } from '@typeorm/sync-adapter/client';

const client = new SyncClient({
  storageAdapter: new IndexedDBAdapter(),
  serverUrl: 'https://api.example.com/sync',
  conflictStrategy: 'last-write-wins'
});

// Works offline, syncs when online
await client.sync();

Real-Time Collaboration

import { UltraFastSyncClient } from '@typeorm/sync-adapter/client';

const client = new UltraFastSyncClient({
  // Sub-millisecond sync operations
  // Intelligent batching and caching
  // Zero-copy operations
});

Enterprise Applications

import { MigrationSystem } from '@typeorm/sync-adapter/migrations';

const migrationSystem = new MigrationSystem({
  tenantId: 'company-123',
  auditLogging: true,
  stagedRollouts: true
});
