I'll create a Next.js project template for a blog website using the App Router. This template will include a basic structure for a blog with a home page, blog post listing, and individual blog post pages. I'll use TypeScript and Tailwind CSS for styling.

Let's start with the main components and pages:

1. First, let's create the main layout:

2. Now, let's create the home page:

3. Let's create the individual blog post page:

4. Now, let's create the Header component:

5. And the Footer component:

6. Let's create a simple utility function to fetch blog posts:

7. Finally, let's add a simple About page:

This template provides a basic structure for a blog website using Next.js with the App Router. It includes:

• A home page that lists blog posts
• Individual blog post pages
• An about page
• A header with navigation
• A footer
• A simple mock function for fetching blog posts (which you'd replace with actual data fetching in a real application)

To use this template, you'd need to:

1. Set up a new Next.js project with TypeScript and Tailwind CSS.
2. Create the file structure as shown in the code snippets.
3. Copy the code into the respective files.
4. Replace the mock getPosts function in lib/posts.ts with actual data fetching logic (e.g., from a CMS, database, or API).
5. Customize the styling and content to fit your needs.

This template provides a solid foundation for building a blog with Next.js. You can expand on it by adding features like pagination, categories, tags, search functionality, and more as your blog grows.
