How does the App Router enhance routing in Next.js 13/14?

The App Router in Next.js 13/14 offers a file-based routing mechanism which simplifies creating and managing routes by automatically mapping files in the 'pages' directory to URLs. It supports dynamic routes, nested routes, and optimizes page loading with automatic code splitting.

Can I integrate Tailwind CSS with Next.js 13/14?

Yes, integrating Tailwind CSS with Next.js 13/14 is straightforward. Install Tailwind via npm, add the necessary configurations in `tailwind.config.js`, and import the CSS in your application. This allows you to utilize utility-first CSS classes throughout your Next.js project.

What are server components in Next.js 14 and how do they work?

Server Components in Next.js 14 allow you to write components that render exclusively on the server. This means they do not send JavaScript to the client for these components, reducing bundle sizes and improving performance by executing logic on the server side before sending HTML to the client.

How can I handle API routes in Next.js 13/14?

API routes in Next.js 13/14 are handled by creating files in the 'pages/api' directory. Each file corresponds to an API endpoint. Next.js automatically treats these files as API routes, allowing you to write server-side code for handling various HTTP requests.

What is the best way to manage state in Next.js applications?

Managing state in Next.js applications can be effectively done using React context or state management libraries like Redux or Recoil. These tools help maintain a predictable state across components, useful for more complex applications with multiple state changes.
