});

Usage Examples

Basic State Management

// Initialize the sync engine
const syncEngine = new SrvraDataSync({
    syncInterval: 30000,
    enableDeltaUpdates: true
});

// Set state with versioning

syncEngine.stateManager.setState('userProfile', {
    name: 'John Doe',
    preferences: { theme: 'dark' }
});

// Get state with metadata

const state = syncEngine.stateManager.getState('userProfile', { 
    withMetadata: true 
});

Real-time Sync with Subscribers

// Subscribe to changes with priority

const subscriberId = syncEngine.stateManager.subscribe(
    'userProfile',
    (value, update) => {
        console.log('Profile updated:', value);
    },
    { priority: 'high' }
);

// Batch updates

syncEngine.stateManager.batch([
    { key: 'preferences', value: { theme: 'light' } },
    { key: 'notifications', value: { enabled: true } }
]);

Conflict Resolution

// Custom merge strategy

syncEngine.conflictResolver.registerCustomStrategy(
    'preference-merge',
    (conflict) => ({
        value: {
            ...conflict.clientValue,
            ...conflict.serverValue,
            lastMerged: Date.now()
        }
    })
);

// Handle specific conflicts

syncEngine.eventBus.subscribe('conflict', (event) => {
    if (event.key === 'userProfile') {
        return syncEngine.conflictResolver.resolveConflict({
            strategy: 'preference-merge',
            ...event
        });
    }
});

Delta Updates

// Enable delta tracking

syncEngine.setState('document', {
    content: 'Initial content',
    metadata: { version: 1 }
}, {
    enableDeltaUpdates: true
});

// Update with delta tracking

syncEngine.setState('document', {
    content: 'Updated content',
    metadata: { version: 2 }
});

Event Handling

// Subscribe to sync events

syncEngine.eventBus.subscribe('sync-complete', (event) => {
    console.log('Sync completed:', event.changes);
});

// Handle network status

syncEngine.eventBus.subscribe('network-status', (status) => {
    if (status === 'offline') {
        // Handle offline mode
    }
});

Advanced State Operations

// State with history tracking

const stateWithHistory = syncEngine.stateManager.setState('audit', {
    actions: [],
    lastUpdate: Date.now()
}, { trackHistory: true });

// Get sync statistics

const stats = syncEngine.getStatistics();
console.log('Sync stats:', stats);

Enterprise Features

// Compression for large datasets

syncEngine.setState('largeDataset', data, {
    compression: true,
    compressionThreshold: 1024
});

// Priority-based sync
syncEngine.sync({
    priority: 'critical',
    immediate: true
});
