Next.js 13 introduces the app directory, changing how we create pages and layouts.

• Routing: Define pages in page.js, and layouts in layout.js.
• Server Components: By default, for better performance.
• Error and Loading States: Managed by error.js and loading.js.

• app/page.js: Defines the UI for the root route /.
• app/layout.js: Contains shared UI like headers or sidebars.

• Articles use @next/mdx package that enables the use of Markdown with JSX
• Pages are created dynamically within the /app directory of the project
• Works with Server Components, which is the default in the App Router

• app/some-directory/error.js: Manages errors within its directory.

• Perform directly inside page components using the Fetch API.

• Client-Side Component: Used use client directive in Newsletter.jsx to handle form interactivity.
• Form Handling: Utilized controlled form inputs with React state for email collection.
• API Integration: Connected with Netlify functions for email subscription.
• User Feedback: Implemented dynamic messaging to confirm subscription status.

• The image galleries are built with Next.js & Cloudinary
• You an view the repo at surfing-image-gallery

To set up a new Next.js 13 project:

2. Modify next.config.js to enable the app directory.
3. Delete pages/index.js to avoid conflicts.
