Performance Optimization Guide¶

WebAssembly Optimizations¶

DOM Operations¶

import { useWasmDom } from '@closure-next/wasm';

// Use WebAssembly for DOM operations
const { createElement, appendChild } = useWasmDom();
const element = createElement('div');
appendChild(container, element);

Event Handling¶

import { useWasmEvents } from '@closure-next/wasm';

// Use WebAssembly for event handling
const { addEventListener } = useWasmEvents();
addEventListener(element, 'click', handler);

String Operations¶

import { useWasmString } from '@closure-next/wasm';

// Use WebAssembly for string operations
const { compare, encode } = useWasmString();
const result = compare(str1, str2);

Memory Management¶

Component Pooling¶

import { useComponentPool } from '@closure-next/core';

const pool = useComponentPool(MyComponent, {
  initialSize: 10,
  maxSize: 100
});

// Reuse components from pool
const component = pool.acquire();
// ... use component ...
pool.release(component);

Event Delegation¶

import { useEventDelegation } from '@closure-next/core';

// Delegate events to reduce memory usage
useEventDelegation(container, {
  click: handleClick,
  mouseenter: handleMouseEnter
});

Build Optimization¶

Tree Shaking¶

// Import only what you need
import { Component } from '@closure-next/core/component';
import { DomHelper } from '@closure-next/core/dom';

Code Splitting¶

// Dynamic imports for code splitting
const MyComponent = await import('./MyComponent');

Monitoring¶

Performance Metrics¶

import { measurePerformance } from '@closure-next/core';

const metrics = await measurePerformance(component, {
  iterations: 100,
  warmup: true
});

console.log(metrics);
// {
//   renderTime: { avg: 1.2, min: 0.8, max: 2.1 },
//   eventTime: { avg: 0.3, min: 0.1, max: 0.8 }
// }

Memory Profiling¶

import { profileMemory } from '@closure-next/core';

const profile = await profileMemory(component);
console.log(profile);
// {
//   heapSize: 1024,
//   nodeCount: 42,
//   listenerCount: 5
// }

Best Practices¶

1. Use WebAssembly for performance-critical operations
2. Implement component pooling for frequently created/destroyed components
3. Use event delegation for large lists/tables
4. Enable tree shaking through proper imports
5. Implement code splitting for large applications
6. Monitor performance metrics in production
7. Profile memory usage regularly
8. Use progressive loading for better perceived performance
