Getting Started with Next.js

Next.js is a powerful React framework that enables you to build server-rendered React applications with ease. In this post, I’ll walk you through the steps to install Next.js and run your first application.

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js: Version 14.0 or later. You can download it from Node.js Official Website.

• npm (Node Package Manager): This usually comes with Node.js. You can check if it's installed by running:

  npm -v

Step 1: Create a New Next.js App

To create a new Next.js application, open your terminal and run the following command:

bash Copy code npx create-next-app@latest my-next-app Replace my-next-app with your desired project name. This command will scaffold a new Next.js project in a folder with that name.

Step 2: Navigate to Your Project Directory

Once the installation is complete, navigate into your project directory:

cd my-next-app

Step 3: Run Your Next.js Application

To start your development server, run:

npm run dev

This command will start your application in development mode. You should see output like this:

Local: http://localhost:3000

Open your browser and navigate to http://localhost:3000 to see your new Next.js application in action!

Step 4: Explore the Project Structure

Your Next.js application comes with a few default files and folders:

pages/: This folder contains your application's pages. Each file in this folder corresponds to a route based on its filename. public/: Static assets like images can be placed here. styles/: This folder contains your CSS files.

Step 5: Create Your First Page

To create a new page, add a new file in the pages/ directory. For example, create about.js:

jsx Copy code // pages/about.js

export default function About() { return About Us; } You can now visit http://localhost:3000/about to see your new page!

Step 6: Building and Deploying

When you're ready to deploy your application, you can build it for production using:

npm run build

This command generates an optimized build of your application in the .next/ directory. You can then start the production server with:

npm start

Conclusion

Congratulations! You’ve successfully installed Next.js and created your first application. There’s much more to explore, including API routes, static site generation, and more.
