   • Use ESLint? Yes/No
   • Use Tailwind CSS? Yes/No
   • Use 'src/' directory? Yes/No

🗂️ Step 2: Understand Project Structure

Next.js organizes your application with simplicity. Key folders include:

• pages/:

  • Houses all your app’s routes.
  • Example: A file named index.js corresponds to the root route /.

• public/:

  • Stores static assets like images.

You can learn more about folder structure in the official documentation.

---

📄 Step 3: Creating and Understanding Pages

In Next.js, each file in the pages/ folder becomes a route.

• Example:
  • pages/index.js → / (Homepage)
  • pages/about.js → /about

To create a new page:

1. Add a new .js file inside the pages/ directory.
2. Write a React component in the file, and Next.js will handle the routing automatically!

🎨 Step 4: Styling Your Next.js App

You have multiple options for styling in Next.js:

• Global CSS: Define styles for the entire app in a single file.
• CSS Modules: Locally scoped styles to avoid name conflicts.
• Tailwind CSS: Utility-first CSS framework for rapid design.
• Sass: CSS preprocessor with features like nesting and variables.
• CSS-in-JS: Write styles directly in your components.

👉 Pro Tip: Tailwind CSS is highly recommended for fast and customizable designs.

To enable Tailwind during setup, select Yes when prompted!

🌍 Step 5: Deploying Your App

Once your app is ready, it's time to share it with the world. Popular deployment platforms include:

• Vercel (Next.js creators)
• Netlify
• AWS

To deploy with Vercel:

1. Install the Vercel CLI:

   npm install -g vercel  
   

2. Run the command:

   vercel  
   

Your app will be live in just a few minutes!
