Next.js 14 Best Practices for AI-Powered Apps

Next.js 14 brings powerful new features that make it perfect for building AI-powered applications. Let's explore the best practices for leveraging these features.

The App Router Revolution

Next.js 14's App Router provides a more intuitive way to structure your applications with:

• Server Components by default
• Improved data fetching
• Better streaming and suspense
• Enhanced developer experience

Server Components for AI Integration

Server Components are perfect for AI API calls because they:

• Keep API keys secure on the server
• Reduce client-side JavaScript
• Improve performance with server-side rendering
• Enable streaming responses

Best Practices

1. Use Server Components for AI Calls

Keep your AI API calls on the server to protect keys and improve security.

2. Implement Streaming

Use streaming to show AI responses as they're generated, improving perceived performance.

3. Error Handling

Always implement proper error handling for AI API calls, as they can be unpredictable.

4. Rate Limiting

Implement rate limiting to prevent abuse and control costs.

Example: Building an AI Chat Interface

Here's a simple example of how to structure an AI chat feature in Next.js 14:

```typescript // app/chat/page.tsx export default async function ChatPage() { return ( <div> <ChatInterface /> </div> ) } ```

Conclusion

Next.js 14 provides an excellent foundation for AI-powered applications. By following these best practices, you can build secure, performant, and user-friendly AI applications.
