<html lang="en">
<body>
<CmsProvider>
{children}
</CmsProvider>
</body>
</html>
);
}
// app/[[...slug]]/page.tsx
import { CmsRouteHandler } from '@ai-growth/nextjs';
export default function DynamicPage() {
return (
<CmsRouteHandler>
<div>This content shows for non-CMS routes</div>
</CmsRouteHandler>
);
}Pages Router (Next.js 12+)
// pages/_app.tsx
import { CmsProvider } from '@ai-growth/nextjs';
import type { AppProps } from 'next/app';
export default function MyApp({ Component, pageProps }: AppProps) {
return (
<CmsProvider>
<Component {...pageProps} />
</CmsProvider>
);
}
// pages/[[...slug]].tsx
import { CmsRouteHandler } from '@ai-growth/nextjs';

</CmsRouteHandler>
);
}3. Advanced Configuration
// lib/cms-config.ts
import { CmsConfig } from '@ai-growth/nextjs';
export const cmsConfig: CmsConfig = {
// Sanity Configuration
projectId: process.env.SANITY_PROJECT_ID!,
dataset: process.env.SANITY_DATASET!,
apiToken: process.env.SANITY_API_TOKEN,
apiVersion: process.env.SANITY_API_VERSION || '2023-05-03',
// Routing Configuration
routePath: process.env.CMS_ROUTE_PATH || '/cms/',
// Performance Configuration
cache: {
enabled: process.env.ENABLE_CACHE === 'true',
ttl: parseInt(process.env.CACHE_TTL || '300'),
staleTime: 300000, // 5 minutes
strategy: 'stale-while-revalidate'
},
// SEO Configuration

export default function MyApp({ Component, pageProps }: AppProps) {
return (
<CmsProvider config={cmsConfig}>
<Component {...pageProps} />
</CmsProvider>
);
}🎨 Template System
Using Default Templates
The package includes responsive, accessible templates:
import { DefaultTemplate, SimpleDefaultTemplate } from '@ai-growth/nextjs';
// Automatic template selection based on content type
<CmsRouteHandler />
// Explicit template usage
<DefaultTemplate content={content} />
<SimpleDefaultTemplate content={content} />Custom Templates
// components/MyCustomTemplate.tsx
import { TemplateProps, CmsImage, SEOHead } from '@ai-growth/nextjs';
export function MyCustomTemplate({ content }: TemplateProps) {
return (
<>
<SEOHead content={content} />
<article className="max-w-4xl mx-auto px-4">
<header>
<h1 className="text-4xl font-bold">{content.title}</h1>
{content.mainImage && (
<CmsImage
image={content.mainImage}
alt={content.title}
priority
className="w-full h-64 object-cover rounded-lg"
/>
)}
</header>
<main>
<ContentBody content={content.content} />
</main>
</article>
</>
);
}
// Register custom template
import { registerTemplate } from '@ai-growth/nextjs';
registerTemplate('custom', MyCustomTemplate);Lazy Loading Templates
import {
DynamicTemplateLoader,
LazyDefaultTemplateV2,
preloadTemplate
} from '@ai-growth/nextjs';
// Dynamic template loading with preloading
<DynamicTemplateLoader
templateName="default-v2"
preloadOnHover={true}
content={content}
/>
// Manual preloading
useEffect(() => {
preloadTemplate('default-v2');
}, []);🔍 SEO Optimization
Automatic SEO
SEO optimization is automatic with smart defaults:
import { SEOHead, useSEOData } from '@ai-growth/nextjs';
// Automatic SEO for CMS content
<CmsRouteHandler /> // SEO included automatically
// Manual SEO control
function MyPage({ content }) {
return (
<>
<SEOHead
content={content}
siteName="My Site"
defaultDescription="Amazing content"
/>
<main>{/* Your content */}</main>
</>
);
}
// Access SEO data in components
function MySEOComponent() {
const seoData = useSEOData();
return <div>Page title: {seoData.title}</div>;
}Advanced SEO Configuration
import { processSEO, generateStructuredData } from '@ai-growth/nextjs';
// Custom SEO processing
const seoData = processSEO(content, {
siteName: 'My Site',
defaultImage: '/default-og.png',
twitterHandle: '@mysite',
customSchema: {
'@type': 'BlogPosting',
publisher: {
'@type': 'Organization',
name: 'My Company'
}
}
});
// Generate structured data
const structuredData = generateStructuredData(content, 'article');🚀 Performance Features
Multi-Layer Caching
import {
CacheProvider,
useCmsContentCached,
CacheManager
} from '@ai-growth/nextjs';
// Global cache configuration
<CacheProvider
config={{
strategy: 'stale-while-revalidate',
ttl: 300000, // 5 minutes
storage: ['memory', 'localStorage', 'indexedDB']
}}
>
<App />
</CacheProvider>
// Use cached content hooks
function MyComponent() {
const {
data,
loading,
error,
stale,
revalidating,
cacheHit
} = useCmsContentCached('posts', 'my-slug');
return (
<div>
{loading && <LoadingSkeleton />}
{error && <ErrorBoundary error={error} />}
{data && <ContentDisplay content={data} />}
{stale && <div>Updating content...</div>}
</div>
);
}
// Manual cache operations
const cacheManager = CacheManager.getInstance();
await cacheManager.invalidateByTag('posts');Image Optimization
import {
OptimizedImage,
CmsImage,
ResponsiveImage,
HeroImage,
AvatarImage
} from '@ai-growth/nextjs';
// Sanity image with optimization

width={800}
height={600}
priority // Above the fold
quality={90}
/>
// Responsive images
<ResponsiveImage
image={content.image}
aspectRatio="16:9"
sizes="(max-width: 768px) 100vw, 50vw"
/>
// Specialized image components
<HeroImage image={heroImage} /> {/* Optimized for LCP */}
<AvatarImage image={authorImage} size="lg" /> {/* User avatars */}Lazy Loading & Code Splitting
import {
LazyLoadComponent,
IntersectionWrapper,
createLazyComponent,
useIntersectionObserver
} from '@ai-growth/nextjs';
// Lazy load below-the-fold content

loader={() => import('./HeavyComponent')}
fallback={<ContentSkeleton />}
rootMargin="100px"
/>
// Intersection-based rendering
<IntersectionWrapper placeholder={<div>Loading...</div>}>
<ExpensiveComponent />
</IntersectionWrapper>
// Custom lazy loading
const LazyComponent = createLazyComponent(
() => import('./MyComponent'),
{
fallback: <LoadingSkeleton />,
retryAttempts: 3
}
);
// Custom intersection observer
function MyComponent() {
const [ref, isVisible] = useIntersectionObserver({
threshold: 0.1,
rootMargin: '50px'
});

Environment Variable Configuration
This library supports both regular environment variables and Next.js public environment variables for better flexibility:
Variable Priority
When configuring the Sanity connection, the library checks for variables in the following order:
- Next.js public variables (
NEXT_PUBLIC_*) if available - Regular variables as fallback
Supported Variables
| Purpose | Next.js Public Variable | Regular Variable | Required? |
|------------------|--------------------------------|-------------------------|-----------------------|
| Project ID | NEXT_PUBLIC_SANITY_PROJECT_ID| SANITY_PROJECT_ID | Yes |
| Dataset | NEXT_PUBLIC_SANITY_DATASET | SANITY_DATASET | Yes |
| API Version | NEXT_PUBLIC_SANITY_API_VERSION| SANITY_API_VERSION | No (default: 2023-05-03) |
| CMS Route Path | NEXT_PUBLIC_CMS_ROUTE_PATH | CMS_ROUTE_PATH | No (default: /cms/) |
| API Token | - | SANITY_API_TOKEN | No* |
*API Token Note: The API token is only required for:
- Writing data to Sanity
- Accessing draft content
- Bypassing the CDN for real-time content
For read-only access to published content, you can omit the API token entirely. The library will automatically use the Sanity CDN for better performance when no token is provided.
Usage in Client vs Server Components
- Server Components: Can access all variables
- Client Components: Can only access
NEXT_PUBLIC_*variables or variables exposed through the client-safe configuration helpers
Example Configuration
# .env file
# Public variables (accessible in browser)
NEXT_PUBLIC_SANITY_PROJECT_ID=your-project-id
NEXT_PUBLIC_SANITY_DATASET=production
# Server-only variables (not exposed to browser)
SANITY_API_TOKEN=your-api-token # Optional, for write access or draft content
