🚀 Usage Examples

Basic Synchronization

import { StatusSynchronizer } from './src/sync/status-synchronizer.js';

const synchronizer = new StatusSynchronizer({
    systems: {
        linear: { enabled: true, priority: 1 },
        github: { enabled: true, priority: 2 },
        postgresql: { enabled: true, priority: 0 }
    }
});

await synchronizer.initialize();
await synchronizer.start();

const result = await synchronizer.synchronizeStatus({
    entityId: 'task-123',
    entityType: 'task',
    status: 'completed'
}, 'linear');

Real-time Updates

import { WebSocketManager } from './src/sync/websocket-manager.js';

const wsManager = new WebSocketManager({ port: 8080 });
await wsManager.start();

// Broadcast status update to all clients
wsManager.broadcast({
    type: 'status_update',
    data: { entityId: 'task-123', status: 'completed' }
});

Custom Conflict Resolution

import { ConflictResolver } from './src/sync/conflict-resolver.js';

const resolver = new ConflictResolver();

resolver.registerResolutionStrategy('custom', async (conflicts, statusUpdate) => {
    // Custom resolution logic
    return {
        resolvedUpdate: statusUpdate,
        reason: 'Applied custom business rules'
