Implementation Details

Performance Optimizations

Lazy Loading

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

const MyLazyComponent = createLazyComponent(() => import('./MyComponent'));

// Usage
const component = await MyLazyComponent.get();
// or preload
MyLazyComponent.preload();

Caching

import { Cache, ComponentPool, ResourcePreloader } from '@closure-next/core';

// Component caching
const cache = new Cache({ maxSize: 100, ttl: 5 * 60 * 1000 });
cache.set('myComponent', component);

// Component pooling
const pool = new ComponentPool(50);
const component = pool.acquire();
pool.release(component);

// Resource preloading
const preloader = new ResourcePreloader();
await preloader.preloadScript('/path/to/script.js');

Bundle Optimization

import { createBundleConfig, defaultChunks } from '@closure-next/core';

const config = createBundleConfig({
  chunks: defaultChunks,
  minChunkSize: 20000,
  maxAsyncRequests: 30
});

Architecture Overview

Core Package

The core package (@closure-next/core) provides the foundation for all framework integrations:

import { Component, DomHelper } from '@closure-next/core';

class MyComponent extends Component {
  protected override createDom(): void {
    this.element = this.domHelper.createElement('div');
    this.element.textContent = 'Hello World';
  }
}

Framework Integrations

Each framework integration package provides framework-specific bindings:

// React
import { ClosureComponent } from '@closure-next/react';
<ClosureComponent component={MyComponent} />

// Vue
import { ClosureComponent } from '@closure-next/vue';
<closure-component :component="MyComponent" />

// Angular
import { ClosureModule } from '@closure-next/angular';
<closure-component [component]="MyComponent"></closure-component>

// Svelte
import { ClosureComponent } from '@closure-next/svelte';
<ClosureComponent component={MyComponent} />

WebAssembly Integration

Performance-critical operations are optimized using WebAssembly:

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

const { createElement, appendChild } = useWasmDom();
const element = createElement('div');
appendChild(container, element);

SSR Implementation

Server-side rendering is implemented with progressive hydration:

// Server
const html = await renderToString(MyComponent);

// Client
await hydrateComponent(MyComponent, container);

Testing Utilities

Comprehensive testing utilities are provided:

import { createTestComponent } from '@closure-next/testing';

const component = createTestComponent(MyComponent);
await simulateEvent(component.getElement(), 'click');
