Automatic memory cleanup prevents memory leaks:

`typescript
import { CSElement } from 'cs-element';

// Enable auto-dispose globally
CSElement.configureReactivity({
autoDispose: true,
debug: true
});

// Create scope for automatic cleanup
const scope = CSElement.createScope();

CSElement.runInScope(scope.id, () => {
const parent = CSElement.computed(() => data.value * 2);
const child1 = CSElement.computed(() => data.value * 2);
const child2 = CSElement.computed(() => data.value * 3);

return child1.value + child2.value;
});

// Cleanup entire scope
CSElement.disposeScope(scope.id);
`

$3

Sophisticated middleware with priorities and conditions:

`typescript
import { CSElement, MiddlewarePriority } from 'cs-element';

// Add high-priority validation middleware
CSElement.plugins.addAdvancedMiddleware('setData', {
name: 'validation-middleware',
priority: MiddlewarePriority.HIGH,
condition: (context) => context.args.key === 'email',
timeout: 1000,
middleware: async (context, next) => {
const { key, value } = context.args;

if (key === 'email' && !isValidEmail(value)) {
throw new Error('Invalid email format');
}

return await next();
}
});

// Add logging middleware with metadata
CSElement.plugins.addAdvancedMiddleware('setData', {
name: 'audit-logger',
priority: MiddlewarePriority.LOW,
middleware: async (context, next) => {
const startTime = Date.now();
const result = await next();

console.log(Operation ${context.operation} took ${Date.now() - startTime}ms);
return result;
}
});
`

Efficient bulk operations with different strategies:

`typescript
import { BatchManager, BatchExecutionStrategy, BatchPriority } from 'cs-element';

const batchManager = new BatchManager();

// Create batch with parallel execution
const batchId = batchManager.createBatch({
executionStrategy: BatchExecutionStrategy.PARALLEL,
maxConcurrency: 5,
errorMode: 'COLLECT_ERRORS'
});

// Add operations with priorities and dependencies
batchManager.addOperation(batchId, {
id: 'create-users',
priority: BatchPriority.HIGH,
execute: async (context) => {
const users = await createMultipleUsers(userData);
return users;
},
validate: async (context) => ({ valid: true, errors: [] }),
maxRetries: 3
});

batchManager.addOperation(batchId, {
id: 'send-notifications',
priority: BatchPriority.NORMAL,
dependencies: ['create-users'], // Wait for users to be created
execute: async (context) => {
const users = context.previousResults.get('create-users');
return await sendWelcomeEmails(users);
}
});

// Execute batch with progress monitoring
const result = await batchManager.executeBatch(batchId);
console.log(Batch completed: ${result.successCount}/${result.totalOperations});
`

$3

Multi-format visualization with interactive features:

`typescript
import { VisualizationManager, VisualizationFormat } from 'cs-element';

const visualizer = new VisualizationManager();

// Generate interactive HTML visualization
const htmlViz = await visualizer.visualize(rootElement, {
format: VisualizationFormat.HTML,
layout: 'tree',
interactive: true,
showData: true,
animations: true,
width: 1200,
height: 800,
theme: 'dark'
});

// Generate SVG for documentation
const svgViz = await visualizer.visualize(rootElement, {
format: VisualizationFormat.SVG,
layout: 'circular',
nodeStyle: {
backgroundColor: '#3498db',
textColor: '#ffffff',
borderRadius: 8
},
edgeStyle: {
color: '#2c3e50',
thickness: 2,
style: 'dashed'
}
});

// ASCII visualization for console output
const asciiViz = await visualizer.visualize(rootElement, {
format: VisualizationFormat.ASCII,
maxDepth: 5,
showIds: true,
showIndices: true
});

console.log(asciiViz.content);
`

$3

Advanced graph analysis and pathfinding:

`typescript
import { CSElement } from 'cs-element';

// Configure graph algorithms
CSElement.configureGraphAlgorithms({
defaultTimeout: 5000,
enableCaching: true,
enableEvents: true
});

// Find shortest path between elements
const path = await CSElement.findShortestPath(sourceElement, targetElement, {
algorithm: 'dijkstra',
weightFunction: (from, to) => calculateDistance(from, to),
maxDepth: 10
});

// Detect cycles in the graph
const cycleResult = await CSElement.detectCycles(rootElement, {
algorithm: 'dfs',
includeVisualization: true
});

if (cycleResult.hasCycles) {
console.log(Found ${cycleResult.cycles.length} cycles);
cycleResult.cycles.forEach(cycle => {
console.log(Cycle: ${cycle.path.join(' -> ')});
});
}

// Analyze graph connectivity
const components = await CSElement.findConnectedComponents(rootElement);
console.log(Graph has ${components.componentCount} connected components);

// Calculate node centrality
const centrality = await CSElement.calculateCentrality(rootElement);
const mostCentralNode = Array.from(centrality.entries())
.sort(([,a], [,b]) => b - a)[0];
console.log(Most central node: ${mostCentralNode[0]} (${mostCentralNode[1]}));
`

Sophisticated comparison with multiple algorithms:

`typescript
import { DiffEngine, DiffAlgorithm, MergeStrategy } from 'cs-element';

const diffEngine = new DiffEngine();

// Compare elements with different algorithms
const myersDiff = diffEngine.computeDiff(sourceElement, targetElement, {
algorithm: DiffAlgorithm.MYERS,
contextLines: 5,
includeVisualization: true
});

const patienceDiff = diffEngine.computeDiff(sourceElement, targetElement, {
algorithm: DiffAlgorithm.PATIENCE,
ignoreWhitespace: true
});

// Three-way merge for conflict resolution
const mergeResult = diffEngine.threeWayMerge(
baseElement,
branchAElement,
branchBElement,
{
strategy: MergeStrategy.AUTO,
conflictResolution: 'auto',
autoResolveThreshold: 0.8
}
);

if (mergeResult.success) {
console.log('Merge completed successfully');
} else {
console.log(${mergeResult.conflicts.length} conflicts need manual resolution);
mergeResult.conflicts.forEach(conflict => {
console.log(Conflict at ${conflict.path.join('.')}: ${conflict.type});
});
}
`

Strongly typed elements with inheritance:

`typescript
import { TypedElementManager, TypedElement } from 'cs-element';

const manager = new TypedElementManager();

// Define base schema
const baseSchema = {
name: 'BaseEntity',
version: '1.0.0',
fields: [
{ name: 'id', type: 'number', required: true },
{ name: 'createdAt', type: 'date', defaultValue: () => new Date() },
{ name: 'updatedAt', type: 'date', nullable: true }
]
};

// Define inherited schema
const userSchema = manager.createInheritedSchema(
'User',
'1.0.0',
'BaseEntity',
[
{ name: 'email', type: 'string', required: true, validation: isValidEmail },
{ name: 'name', type: 'string', required: true },
{ name: 'role', type: 'enum', values: ['user', 'admin'], defaultValue: 'user' }
]
);

manager.registerSchema(baseSchema);
manager.registerSchema(userSchema);

// Create typed element
const user = await manager.createElement('User', {
id: 1,
email: 'john@example.com',
name: 'John Doe',
role: 'admin'
});

// Type-safe field access
const email: string = user.getField('email');
await user.setField('role', 'user'); // Type-checked
`

Dependency injection and service management:

`typescript
import { services } from 'cs-element';

// Access built-in services
const persistenceManager = services.persistence;
const reactivityManager = services.reactivity;
const historyManager = services.history;

// Configure services
services.configureHistory({
maxHistorySize: 1000,
enableCompression: true,
autoSnapshot: true,
snapshotInterval: 5000
});

services.configureReactivity({
autoDispose: true,
debug: false,
warnMemoryLeaks: true,
maxComputedDepth: 50
});

// Access global element registry
const allElements = services.registry.getAllElements();
const userElements = services.registry.getElementsByName('User');
const specificElement = services.registry.getElementById('element-123');
`

⚛️ React Integration

`typescript
import { useCSElement } from 'cs-element/react';

function MyComponent() {
const {
root,
createElement,
query,
connected,
stats
} = useCSElement({
autoConnect: true,
enableReactivity: true,
enablePersistence: true
