  if (req.method === "GET") {
    const projects = await prisma.project.findMany();
    return res.json(projects);
  }
  
  if (req.method === "POST") {
    await authMiddleware(req, res);
    const { title, description } = req.body;
    const project = await prisma.project.create({ data: { title, description } });
    return res.status(201).json(project);
  }

  return res.status(405).json({ error: "Method not allowed" });
}

📌 Phase 4: Authentication & Security

✅ Task 4: Implementing Authentication with NextAuth.js

Features:
- OAuth login via Google/GitHub.
- JWT-based session management.
- Protect admin routes.

Code Implementation

const openai = new OpenAIApi(config);

export default async function handler(req, res) {
  const response = await openai.createCompletion({
    model: "gpt-4",
    prompt: `Suggest 3 innovative project ideas for a developer specializing in React and Next.js.`,
    max_tokens: 50,
  });
  res.json(response.data.choices.map((c) => c.text));
}

📌 Phase 6: Deployment & Optimization

✅ Task 6: Deployment Strategy

✅ CMS with Markdown, dynamic routing, ISR, and AI integrations
✅ Scalable, production-ready, deployable on Vercel

🚀 DevXPro: The Ultimate Full-Stack Next.js Capstone Project

Now that we have a clear roadmap and working components, let's dive deeper into the nitty-gritty details. We'll go over best practices, common pitfalls, optimizations, checklists, and hints to ensure that this project is production-grade and ready for real-world deployment.

📌 Phase 7: Fine-Tuning the Frontend

✅ Task 7: Optimize UI & User Experience

A developer's portfolio is not just functional but also visually appealing. Clients often request:

Dark Mode & Theme Toggle: Implement a Tailwind-based theme switcher.
Smooth Page Transitions: Use Framer Motion for animations.
Responsive Design: Ensure mobile-first development.
Lazy Loading Images & Assets: Use next/image with loading="lazy".

💡 Hints for Smooth Animations

Use framer-motion for page transitions.

Animate elements on page load:

import { motion } from "framer-motion";
const Page = () => {

return (

<motion.div initial={{ opacity: 0 }} animate={{ opacity: 1 }} transition={{ duration: 0.5 }}>

<h1 className="text-4xl">Welcome to DevXPro</h1>

</motion.div>

);

};

Animate text while scrolling:

<motion.h1 whileInView={{ scale: 1.1 }}>Scroll-triggered Animation</motion.h1>

📌 Phase 8: Implementing Advanced Next.js Features

✅ Task 8: Optimizing Data Fetching

One of the biggest mistakes Next.js developers make is improper data fetching, leading to performance issues. Follow these rules:

Scenario	Method to Use
SEO-sensitive pages (Blogs, Projects)	getStaticProps() + ISR
User-specific data (Auth, Dashboards)	getServerSideProps()
Frequently updating data	SWR with API routes
AI-generated suggestions	Client-side API call

💡 Code Hint: Dynamic Imports for Performance

import dynamic from "next/dynamic";
const HeavyComponent = dynamic(() => import("@/components/HeavyComponent"), { ssr: false });

📌 Phase 12: Deployment & Security

✅ Task 12: Secure Deployment Checklist

Before deploying to Vercel, follow these steps:

✔ Sanitize API Inputs (escape() for SQL queries).
✔ Rate-limit APIs (use express-rate-limit).
✔ Use HTTPS & secure cookies.
✔ Avoid hardcoded credentials (use dotenv).
✔ Implement Content Security Policy (CSP).

💡 Code Hint: Secure Headers in `next.config.js`

module.exports = {
  async headers() {
    return [
      {
        source: "/(.*)",
        headers: [
          { key: "X-Content-Type-Options", value: "nosniff" },
          { key: "Referrer-Policy", value: "no-referrer-when-downgrade" },
        ],
      },
    ];
  },
};

🎯 Do's and Don'ts for a Professional Codebase

✅ Do’s

✔ Follow Next.js’s best practices (ISR, SSR, CSR usage).
✔ Use TypeScript for better type safety.
✔ Implement SEO best practices (next/head, schema markup).
✔ Write unit tests (Jest, Cypress).
✔ Keep API calls minimal to reduce latency.
✔ Use Eslint & Prettier for consistent formatting.

❌ Don’ts

❌ Store JWTs in localStorage (use httpOnly cookies instead).
❌ Hardcode API keys in frontend (use Next.js environment variables).
❌ Fetch all data on the client-side (use ISR/SSG instead).
❌ Forget error handling (always return JSON { error: "message" }).
❌ Ignore security headers & rate-limiting.

🎯 Final Takeaways

🚀 You’re now equipped to build a full-stack, AI-powered, production-grade Next.js application!

✅ This project mimics a real-world SaaS application.
✅ It implements authentication, CMS, AI features, security, and optimizations.
✅ Deployable on Vercel with a solid database and caching layer.

🔥 Next steps? Write unit tests, document your API, and deploy it! 💪
Remember: The difference between an average and a great developer is in the attention to details & optimizations! 🚀

  const { data, error } = useSWR('/api/ai/suggestions', fetcher, {
    revalidateOnFocus: false,
    onSuccess: (data) => {
      localStorage.setItem('lastSuggestions', JSON.stringify(data));
    }
  });

  return (
    <div className="ai-panel">
      <h3>Suggested Projects</h3>
      <div className="suggestions-grid">
        {data?.map((suggestion, index) => (
          <AICard 
            key={index}
            suggestion={suggestion}
            onFeedback={(rating) => handleFeedback(rating)}
          />

      </div>
    </div>
  );
}

AI Requirements:

6. Security Implementation

6.1 Client-Side Security

// middleware.ts
export { default } from "next-auth/middleware";

export const config = {
  matcher: [
    "/cms/:path*",
    "/api/protected/:path*"
  ],
};

// Additional CSP headers
Content-Security-Policy: 
  "default-src 'self';
   script-src 'self' 'unsafe-inline' *.vercel.app;
   style-src 'self' 'unsafe-inline';
   img-src 'self' data: res.cloudinary.com;
   connect-src 'self' *.openai.com"

Security Requirements:

Strict CSP headers
XSS protection via DOMPurify
CSRF tokens for all form submissions
Rate limiting visible in UI
Session timeout handling

7. Documentation & Testing

7.1 Testing Matrix

// cypress/e2e/cms.cy.ts
describe('CMS Workflow', () => {
  beforeEach(() => {
    cy.loginAsEditor();
  });

  it('Creates new project with AI suggestions', () => {
    cy.visit('/cms/projects/new');
    cy.get('#ai-suggest').click();
    cy.get('.suggestion-card').first().click();
    cy.get('#project-title').should('have.value', 'AI Suggested Project');
  });
});

Testing Requirements:

100% coverage for core components
Visual regression testing
Lighthouse CI integration
API contract testing

8. Deployment Configuration

8.1 Vercel Specific Settings

# vercel.json
{
  "buildCommand": "npm run build",
  "outputDirectory": ".next",
  "framework": "nextjs",
  "regions": ["fra1"],
  "experimental": {
    "serverComponentsExternalPackages": ["@prisma/client"]
  }
}
