Getting Started with Next.js: Structure, Tips & Deployment | Blog Post

What is Next.js?

Next.js is a powerful React-based framework that enables developers to build fast, SEO-friendly web applications with minimal setup. Whether you're building a static marketing page, a full-stack SaaS product, or a blog — Next.js handles routing, rendering modes, and performance out of the box.

Why Choose Next.js?

File-based routing: No need for React Router. Just drop a file in /app or /pages and it becomes a route.
Server-side rendering & static generation: Easily switch between SSR, SSG, or client-side rendering.
Built-in API routes: Create full-stack apps without needing a separate backend.
Seamless Vercel deployment: Optimized for Vercel hosting.

Project Setup

Let’s create a new Next.js app using the App Router approach (recommended in Next.js 13+).

npx create-next-app@latest my-nextjs-app --experimental-app

After the CLI prompts, your project will be initialized with the following folder structure:

Project Structure Overview

.
      ├── app/                // App Router entrypoint
      │   ├── layout.tsx      // Root layout (wrapping component)
      │   ├── page.tsx        // Homepage ("/")
      │   └── (routes)/       // Sub-routes as directories
      ├── components/         // Shared UI components
      ├── public/             // Static assets (e.g. images, fonts)
      ├── styles/             // Tailwind/global styles
      ├── lib/                // Utilities, helper functions
      ├── .env.local          // Environment variables
      ├── tailwind.config.ts  // Tailwind configuration
      ├── next.config.js      // Framework-level config
      └── package.json

This modular layout promotes separation of concerns and scalability.

Adding Tailwind CSS

Tailwind helps you build modern UIs rapidly. To install it:

npm install -D tailwindcss postcss autoprefixer
      npx tailwindcss init -p

Update your tailwind.config.ts to include:

content: ["./app/**/*.{js,ts,jsx,tsx}", "./components/**/*.{js,ts,jsx,tsx}"]

And in your global CSS file (usually globals.css):

@tailwind base;
      @tailwind components;
      @tailwind utilities;

Routing with the App Router

Next.js App Router introduces nested layouts, dynamic routing, and server components by default.

Create a route:

// app/about/page.tsx
      export default function AboutPage() {
        return <h1>About Me</h1>
      }

This will now be available at /about.

Nested Layouts:

// app/dashboard/layout.tsx
      export default function DashboardLayout({ children }) {
        return (
          <div>
            <Sidebar />
            {children}
          </div>
        )
      }

This layout wraps all routes under /dashboard.

Environment Configuration

Create a .env.local file in your root for environment-specific settings:


      NEXT_PUBLIC_API_BASE_URL=https://api.example.com
      NEXT_PUBLIC_ENV=development

Access these with process.env.NEXT_PUBLIC_* in your codebase.

Useful Libraries to Add

clsx / tailwind-merge – Handle conditional classNames.
shadcn/ui – Prebuilt headless UI components with Tailwind.
framer-motion – For page transitions and motion effects.
zod – For schema validation in forms or APIs.

Deploying to Vercel (Free Hosting)

Push your code to GitHub.
Go to vercel.com and sign in.
Click “New Project” and import your GitHub repo.
Vercel auto-detects the framework and deploys your app instantly.

Bonus: You get previews on every commit and custom domains. You can also add environment variables from the Vercel dashboard.

Final Thoughts

Next.js offers a scalable foundation whether you're just starting out or building enterprise-level applications. Understanding the project structure and deployment process will help you ship better, faster.

If you're new to the ecosystem, start small — build a portfolio, a blog, or a dashboard UI. The tooling is designed to grow with you.
