Next.js (14.2.18) is outdated 🆕 — Error: Unsupported Server Component type

Next.js is a powerful React framework for building fast, scalable, and feature-rich web applications. Known for its seamless integration of server-side rendering, static site generation, and a developer-friendly experience, Next.js is widely adopted by developers aiming for optimized performance and modern web standards.

However, running an outdated version of Next.js, like 14.2.18, can limit access to critical security updates, new features, and performance improvements. In this article, I’ll guide you through the process of updating Next.js on your server, ensuring your application stays up-to-date and benefits from the latest advancements. Whether you're a seasoned developer or just getting started, this step-by-step guide will help you resolve this issue quickly and effectively.

Let's update Next.js to the latest stable version to fix these issues:

1. First, stop the development server if it's running (Control + C)
2. Update Next.js in your package.json. You can either:

Or manually update your package.json and then reinstall:

# Open package.json
cat > package.json << 'EOL'
{
  "name": "media-kit",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {
    "next": "14.0.4",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "@radix-ui/react-slot": "^1.0.2",
    "class-variance-authority": "^0.7.0",
    "clsx": "^2.0.0",
    "lucide-react": "^0.294.0",
    "tailwind-merge": "^2.1.0",
    "tailwindcss-animate": "^1.0.7",
    "recharts": "^2.10.3"
  },
  "devDependencies": {
    "@types/node": "^20",
    "@types/react": "^18",
    "@types/react-dom": "^18",
    "autoprefixer": "^10.0.1",
    "eslint": "^8",
    "eslint-config-next": "14.0.4",
    "postcss": "^8",
    "tailwindcss": "^3.3.0",
    "typescript": "^5"
  }
}
EOL

# Then reinstall dependencies
npm install

3. Clear Next.js cache:

4. Make sure your app/page.tsx is using the correct syntax for Server Components:

cat > app/page.tsx << 'EOL'
import MediaKit from '@/components/media-kit'

export default function Page() {
  return (
    <main>
      <MediaKit />
    </main>
  )
}
EOL

5. Start the development server again:

This should resolve both the outdated version warning and the Server Component error.
