export default function RootLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<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+)**
```tsx
// 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';
export default function CatchAllPage() {
return (
<CmsRouteHandler>
<div>Fallback content for non-CMS routes</div>
</CmsRouteHandler>
);
}
```
### 3. Advanced Configuration
```tsx
// 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
seo: {
siteName: 'My Awesome Site',
defaultDescription: 'Welcome to our content hub',
twitterHandle: '@myhandle',
defaultImage: '/og-image.png'
}
};
// pages/_app.tsx or app/layout.tsx
import { CmsProvider } from '@ai-growth/nextjs';
import { cmsConfig } from '../lib/cms-config';
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:
```tsx
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
```tsx
// 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
```tsx
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:
```tsx
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
```tsx
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
```tsx
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
```tsx
import {
OptimizedImage,
CmsImage,
ResponsiveImage,
HeroImage,
AvatarImage
} from '@ai-growth/nextjs';
// Sanity image with optimization
<CmsImage
image={content.mainImage}
alt="Hero image"
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
```tsx
import {
LazyLoadComponent,
IntersectionWrapper,
createLazyComponent,
useIntersectionObserver
} from '@ai-growth/nextjs';
// Lazy load below-the-fold content
<LazyLoadComponent
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'
});
return (
<div ref={ref}>
{isVisible && <ExpensiveContent />}
</div>
);
}
```
## 🛡️ Error Handling
### Error Boundaries
```tsx
import {
ErrorBoundary,
CmsErrorBoundary,
ApiErrorBoundary,
withErrorBoundary
} from '@ai-growth/nextjs';
// Wrap components with error boundaries
<ErrorBoundary
fallback={<ErrorPage />}
onError={(error, errorInfo) => console.error(error)}
>
<MyComponent />
</ErrorBoundary>
// CMS-specific error handling
<CmsErrorBoundary>
<CmsContent />
</CmsErrorBoundary>
// HOC pattern
const SafeComponent = withErrorBoundary(MyComponent, {
fallback: <div>Something went wrong</div>
});
```
### Error Logging
```tsx
import {
ErrorLogger,
logError,
logCriticalError
} from '@ai-growth/nextjs';
// Automatic error logging (configured in CmsProvider)
// Errors are automatically categorized and sent to monitoring
// Manual error logging
try {
// risky operation
} catch (error) {
logError(error, {
category: 'api',
severity: 'error',
context: { userId: 'user123' }
});
}
// Critical errors
logCriticalError(new Error('Payment failed'), {
context: { orderId: 'order-123' }
});
```
### Fallback Content
```tsx
import {
FallbackContent,
ContentFallback,
useFallbackContent
} from '@ai-growth/nextjs';
// Provider with fallback content
<FallbackContentProvider>
<App />
</FallbackContentProvider>
// Component with fallback
<ContentFallback
type="post"
fallbackTitle="Content Unavailable"
fallbackMessage="This content is temporarily unavailable."
showRetry
onRetry={() => window.location.reload()}
/>
// Hook for fallback content
function MyComponent() {
const { getFallbackContent } = useFallbackContent();
const fallback = getFallbackContent('post', 'Unable to load post');
return <div>{fallback}</div>;
}
```
## 🎣 Hooks & Context
### Content Hooks
```tsx
import {
useCmsContent,
useCmsContentList,
useCmsContentCached,
useContentPreload
} from '@ai-growth/nextjs';
// Fetch single content
const { data, loading, error } = useCmsContent('posts', slug);
// Fetch content list
const { data: posts, loading } = useCmsContentList('posts', {
limit: 10,
sort: 'publishedAt desc'
});
// Cached content (recommended)
const { data, stale, revalidating } = useCmsContentCached('posts', slug);
// Preload content
const preloadPost = useContentPreload();
preloadPost('posts', 'upcoming-post-slug');
```
### CMS Context
```tsx
import { useCms, useCmsTheme, useCmsTemplate } from '@ai-growth/nextjs';
function MyComponent() {
const { config, client, isConnected } = useCms();
const theme = useCmsTheme();
const { currentTemplate, setTemplate } = useCmsTemplate();
return (
<div className={theme.container}>
Status: {isConnected ? 'Connected' : 'Disconnected'}
Template: {currentTemplate}
</div>
);
}
```
### Cache Context
```tsx
import {
useCacheMetrics,
useCacheOperations,
useCacheDebug
} from '@ai-growth/nextjs';
function CacheDebug() {
const { hitRatio, size, responseTime } = useCacheMetrics();
const { invalidate, clear } = useCacheOperations();
const debugInfo = useCacheDebug();
return (
<div>
<p>Hit Ratio: {hitRatio}%</p>
<p>Cache Size: {size} entries</p>
<p>Avg Response: {responseTime}ms</p>
<button onClick={() => clear()}>Clear Cache</button>
</div>
);
}
```
## 📱 Loading States
```tsx
import {
LoadingFallback,
CmsLoadingFallback,
Skeleton,
ContentSkeleton,
useLoading
} from '@ai-growth/nextjs';
// Pre-built loading components
<LoadingFallback message="Loading content..." />
<CmsLoadingFallback contentType="article" />
// Skeleton components
<Skeleton width={200} height={20} />
<ContentSkeleton />
// Loading state management
function MyComponent() {
const { isLoading, setLoading } = useLoading();
const handleSubmit = async () => {
setLoading(true);
try {
await submitData();
} finally {
setLoading(false);
}
};
return (
<button onClick={handleSubmit} disabled={isLoading}>

## 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:
1. Next.js public variables (`NEXT_PUBLIC_*`) if available
2. 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
# .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
```
