How to Setup Next JS in Node JS

Next.js is a powerful React framework that enables developers to build fast, scalable web applications with ease. It simplifies the process of server-side rendering and static site generation, making it an excellent choice for building modern web applications.

On the other hand, Node.js is a runtime environment that allows you to run JavaScript on the server. It’s fast, lightweight, and designed for building scalable network applications. By combining Next.js with Node.js, you can create high-performance web applications that run both on the server and the client.

In this guide, we will cover you through the steps to setup Next js project in Node.js on Windows.

Installing Node.js on Windows

To set up Next.js, the first step is to install Node.js on your Windows machine. Node.js is essential for running JavaScript code outside the browser, and it comes with npm (Node Package Manager) that you’ll use to install Next.js and other libraries.

Step 1: Download Node.js

Visit the official Node.js website to download the installer. It’s recommended to download the LTS version for better stability, especially for production applications:

Step 2: Run the Installer

Once you’ve downloaded the installer, double-click on the file to start the installation process. Follow the on-screen instructions to complete the setup. Make sure to select the option that adds Node.js to your system’s PATH variable, which allows you to run Node.js from the command line.

Step 3: Verify the Installation

After the installation is complete, open Command Prompt or PowerShell and type the following command to verify that Node.js is installed correctly:

node -v

npm -v

This will return the version of Node.js that’s installed on your system. Both commands should display the version numbers if the installation was successful.

For more detailed instructions refer to our guide on how to install Node.js and NPM on Windows system.

Setting up Next.js in Node.js

Once Node.js is installed and verified, the next step is to set up Next.js for your project. This process involves creating a new Next.js app and running it locally on your Windows machine. Here’s a step-by-step guide to help you get started.

Step 1: Create a New Next.js Project

With Node.js in place, you can now create a Next.js project using the `npx` command. This command runs the latest version of Next.js without needing to install it globally.

Open command and navigate to the directory where you want your Next.js project to be created. After that run the following command to create a new Next.js app:

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

Replace `my-nextjs-app` with your preferred project name.

Step 2: Navigate to Your Project Folder

Once the setup is complete, move into your newly created project directory by running:

cd my-nextjs-app

Step 3: Start the Development Server

Now that you’ve set up your Next.js project, it’s time to start the development server. This will allow you to view your app in action.

Run the following command to start the server:

npm run dev

This will start the server, and your app will be available at `http://localhost:3000` in your web browser. Open your browser and go to that address to see your new Next.js app running.

Step 4: Explore Your Next.js Project

With your Next.js app running, you can now explore the project structure. Some important directories to note are:

• pages/: This is where your application’s pages are located. Each file in this directory corresponds to a route in your app.
• public/: Here you’ll store static assets, like images or fonts, which are publicly accessible.
• styles/: This folder contains your global CSS files that define the overall look and feel of your application.

Now that your Next.js app is set up and running, you’re ready to start developing your web application!

Features of Next.js

Next.js offers a range of powerful features that make it an excellent choice for building modern web applications. Below are some of the key features that make Next.js stand out.

1. Server-Side Rendering (SSR)

One of Next.js’s standout features is Server-Side Rendering (SSR). This allows pages to be rendered on the server, ensuring faster initial page load times and improving SEO. When a user visits your site, the server sends a fully rendered page, making it easier for search engines to crawl your content.

2. Static Site Generation (SSG)

Next.js supports Static Site Generation (SSG), which allows you to pre-render pages at build time. This results in faster page loads as the HTML is generated once and reused for every request. SSG is perfect for sites with content that doesn’t change frequently.

3. Automatic Code Splitting

Next.js automatically splits your code into smaller bundles. Instead of loading the entire app at once, it only loads the necessary parts, improving performance and reducing initial load times.

4. API Routes

Next.js allows you to build backend API routes directly within your project. These API routes can handle server-side logic and interact with databases, making it easier to create full-stack applications without the need for an external backend.

5. Built-in CSS and Sass Support

Next.js has built-in support for CSS and Sass, which means you can import styles directly into your components without additional setup. It also supports CSS modules for scoped styling, ensuring that styles don’t leak across components.

6. Image Optimization

Next.js offers automatic image optimization by providing the `next/image` component. This feature optimizes images on-demand, resizing them based on the device and format, which helps improve performance and load times across various devices.

Conclusion

In this article, we discussed how to set up Next.js in Node.js on a Windows machine. First, we installed Node.js, verified its installation, and then created a new Next.js project using the `npx` command. Once the project was set up, we started the development server to run the app locally.

We also explored the key features of Next.js, such as Server-Side Rendering (SSR), Static Site Generation (SSG), automatic code splitting, and built-in support for CSS and Sass. These features make Next.js a powerful framework for building fast, efficient, and scalable web applications. With everything in place, you’re now ready to begin developing with Next.js!
