NEW! Fluent Schema Composer ⚡

Build complex schemas with ease using our fluent API:

import { product, article, organization } from 'ai-seo';

const productSchema = product()
  .name('Amazing Product')
  .description('This product will change your life')
  .image(['product1.jpg', 'product2.jpg'])
  .brand('YourBrand')
  .offers({ price: 99.99, priceCurrency: 'USD' })
  .rating(4.8, 127)
  .inject(); // Automatically injects into DOM

// Article schema
const blogPost = article()
  .name('How to Use Schema Composer')
  .author('Jane Doe')
  .publisher('Tech Blog')
  .datePublished('2024-01-15T10:00:00Z')
  .keywords(['seo', 'schema', 'javascript'])
  .build(); // Returns schema object

NEW! Framework Integrations 🎭

React Hooks

import { Frameworks } from 'ai-seo';

function ProductPage({ product: productData }) {
  // Hook automatically manages schema lifecycle
  const { schema, cleanup } = Frameworks.React.useSEO(() => 
    product()
      .name(productData.name)
      .brand(productData.brand)
      .offers({ price: productData.price })
      .build()
  );

  return <div>Product: {productData.name}</div>;
}

// Higher-order component
const WithSEO = Frameworks.React.withSEO(MyComponent, (props) => 
  article().name(props.title).author(props.author).build()
);

Vue Composables

<script setup>
import { Frameworks } from 'ai-seo';
import { ref, computed } from 'vue';

const productData = ref({ name: 'Product', price: 99 });

// Reactive schema management
const { element, update } = Frameworks.Vue.useSEO(
  computed(() => 
    product()
      .name(productData.value.name)
      .offers({ price: productData.value.price })
      .build()
  )
);
</script>

Svelte Stores

<script>
import { Frameworks } from 'ai-seo';

// Create reactive schema store
const schemaStore = Frameworks.Svelte.createSEOStore(
  product().name('Initial Product').build()
);

// Update schema reactively
function updateProduct(newData) {
  schemaStore.update(schema => 
    product().name(newData.name).brand(newData.brand).build()
  );
}
</script>

NEW! Industry Templates 📋

Pre-built schemas for common industries:

import { Templates } from 'ai-seo';

// E-commerce product page
const productSchema = Templates.ecommerce.productPage({
  name: 'Wireless Headphones',
  price: 199.99,
  brand: 'AudioTech',
  inStock: true,
  rating: 4.5,
  reviewCount: 234
});

// Restaurant listing
const restaurantSchema = Templates.restaurant.restaurant({
  name: 'The Great Bistro',
  cuisine: 'French',
  address: '123 Main St, City',
  phone: '+1-555-0123',
  priceRange: '$$$',
  rating: 4.7,
  reviewCount: 89
});

// Real estate property
const propertySchema = Templates.realEstate.realEstateProperty({
  title: 'Beautiful Family Home',
  price: 450000,
  bedrooms: 3,
  bathrooms: 2,
  squareFeet: 1800,
  agent: { name: 'John Smith', phone: '+1-555-0456' }
});

// Blog post
const blogSchema = Templates.content.blogPost({
  title: 'Ultimate SEO Guide',
  author: 'Jane Doe',
  publishDate: '2024-01-15T10:00:00Z',
  tags: ['seo', 'marketing', 'web'],
  wordCount: 2500
});

NEW! Advanced Caching System 🚀

Intelligent schema caching with automatic optimization:

import { Cache } from 'ai-seo';

// Configure intelligent caching
Cache.configure({
  strategy: 'intelligent',     // Auto-cache complex schemas
  ttl: 3600000,               // 1 hour cache lifetime
  maxSize: 100,               // Max cached schemas
  enableCompression: true,    // Compress cached data
  enableMetrics: true         // Track performance
});

// Get performance metrics
const metrics = Cache.getMetrics();
console.log(`Cache hit rate: ${metrics.hitRate}%`);
console.log(`Total schemas cached: ${metrics.cacheSize}`);

NEW! Lazy Loading System ⚡

Load schemas only when needed for better performance:

import { LazySchema } from 'ai-seo';

// Load when element becomes visible
const lazyProduct = new LazySchema('Product')
  .loadWhen('visible')
  .withData(() => ({
    name: 'Premium Headphones',
    price: 199.99,
    inStock: true
  }))
  .configure({
    rootMargin: '50px',    // Load 50px before visible
    threshold: 0.1         // Load when 10% visible
  })
  .inject();

// Load on user interaction
const lazyArticle = new LazySchema('Article')
  .loadWhen('interaction')
  .withData(() => getArticleData())
  .inject();

// Custom loading condition
const lazyEvent = new LazySchema('Event')
  .loadWhen('custom', () => shouldLoadEvent())
  .withData(getEventData)
  .inject();

NEW! Performance Monitoring 📊

Track and optimize schema performance:

import { Performance } from 'ai-seo';

// Get comprehensive performance report
const report = Performance.getReport();

console.log('=== Performance Report ===');
console.log(`Average injection time: ${report.averageInjectionTime.toFixed(2)}ms`);
console.log(`Cache hit rate: ${report.cacheHitRate}%`);
console.log(`Performance score: ${report.performanceScore}/100`);
console.log(`Total schemas: ${report.totalSchemas}`);

// Get actionable recommendations
report.recommendations.forEach(rec => {
  console.log(`${rec.severity.toUpperCase()}: ${rec.message}`);
  console.log(`Action: ${rec.action}`);
});

// Example output:
// MEDIUM: Many schemas detected. Consider lazy loading for better performance.
// Action: Use LazySchema for non-critical schemas: new LazySchema("Product").loadWhen("visible")

NEW! Enhanced Validation 🔍

Get detailed feedback on your schemas:

import { validateSchemaEnhanced, getSchemaSuggestions } from 'ai-seo';

const schema = product().name('Test Product').build();

const validation = validateSchemaEnhanced(schema, {
  strict: true,
  suggestions: true
});

console.log(`Schema quality score: ${validation.score}/100`);
console.log('Errors:', validation.errors);
console.log('Warnings:', validation.warnings);
console.log('Suggestions:', validation.suggestions);

// Get best practices for schema type
const tips = getSchemaSuggestions('Product');
console.log('Product schema tips:', tips);

NEW! Analytics Integration 📈

Track schema performance and effectiveness:

import { Analytics } from 'ai-seo';

// Track schema injections
const schema = product().name('Tracked Product').build();
initSEO({ 
  schema, 
  analytics: (event) => {
    console.log('Schema event:', event);
    // Send to your analytics service
  }
});

// Get performance metrics
const metrics = Analytics.getSchemaMetrics();
console.log(`Total schemas: ${metrics.total_schemas}`);
console.log('Schema types:', metrics.schema_types);

// Export analytics data
const csvData = Analytics.exportAnalytics('csv');
const jsonData = Analytics.exportAnalytics('json');

  name: 'Awesome Product',
  description: 'The best product ever made',
  image: ['product1.jpg', 'product2.jpg'],
  brand: 'Your Brand',
  offers: {
    price: 99.99,
    priceCurrency: 'USD',
    availability: 'https://schema.org/InStock'
  },
  aggregateRating: {
    ratingValue: 4.8,
    reviewCount: 127
  }
});

initSEO({ schema: productSchema });

Article Schema

const articleSchema = SchemaHelpers.createArticle({
  headline: 'How to Use AI-SEO',

Next.js Integration

// app/layout.js
import { SSR, organization } from 'ai-seo';
import Head from 'next/head';

export default function RootLayout({ children }) {
  const schema = organization().name('Your Company').url('https://yoursite.com').build();
  const { jsonLd, socialMeta } = SSR.frameworks.nextJS.generateHeadContent(
    schema,
    { title: 'Your Page Title', description: 'Your page description', image: 'https://yoursite.com/og-image.jpg' }
  );

  return (
    <html>
      <Head>
        <script
          type="application/ld+json"
          dangerouslySetInnerHTML={{ __html: jsonLd.match(/<script[^>]*>([\s\S]*)<\/script>/)?.[1] || '' }}
        />
        <div dangerouslySetInnerHTML={{ __html: socialMeta }} />
      </Head>
      <body>{children}</body>
    </html>
  );
}

export default {
  head() {
    const schema = SchemaHelpers.createArticle({
      headline: this.title,
      author: this.author
    });

    return SSR.frameworks.nuxt.generateHeadConfig(schema, {
      title: this.title,
      description: this.description
    });
  }
}

Manual SSR

import { SSR } from 'ai-seo';

// Generate script tag string
const scriptTag = SSR.generateScriptTag(schema, { pretty: true });

// Generate multiple script tags
const multipleScripts = SSR.generateMultipleScriptTags(schemas);

// Generate social media meta tags
const socialMeta = SSR.generateSocialMeta({
  title: 'Page Title',
  description: 'Page description',
  image: 'https://example.com/image.jpg',
  url: 'https://example.com/page'
});

Schema Management

import { 
  listSchemas, 
  getSchema, 
  removeSchema, 
  removeAllSchemas 
} from 'ai-seo';

// List all injected schemas
const schemas = listSchemas();
console.log(`Found ${schemas.length} schemas`);

// Get specific schema
const schema = getSchema('my-schema-id');

// Remove specific schema
removeSchema('my-schema-id');
