Next.js Installation Instructions

Next.js is one of the most popular frameworks for building React applications with features like server-side rendering, static site generation, and more. In this tutorial, we will walk through the steps to install Next.js and set up your project.

1. Set Up Your Project Folder

First, create a folder for your project. This folder will hold all of your Next.js application files.

Open a terminal and navigate to where you want to create your project folder.
Create a new folder for your project. For example:

mkdir project

Navigate to that folder:

cd project

Open the folder in Visual Studio Code by running the following command in your terminal:

code .

Initialize Your Next.js Project Now that you are inside your project folder, it’s time to set up your Next.js project. Open your terminal in VS Code using Ctrl + ~ and run the following command:

npx create-next-app@latest .

This command will set up a new Next.js project in the root of your current folder. Next, you’ll be asked a series of configuration questions.

Configuration Options: After running the command, you’ll see a set of prompts like the following:

What is your project named? Project
Would you like to use TypeScript? No / Yes
Would you like to use ESLint? No / Yes
Would you like to use Tailwind CSS? No / Yes
Would you like your code inside a `src/` directory? No / Yes
Would you like to use App Router? (recommended) No / Yes
Would you like to use Turbopack for `next dev`? No / Yes
Would you like to customize the import alias (`@/*` by default)? No / Yes
What import alias would you like configured? @/*

Breakdown of Each Option:

Project Name: The name of your Next.js project. You can customize it or use the default name.
TypeScript: If you prefer to use TypeScript, select "Yes." Otherwise, selecting "No" will generate a JavaScript-based project.
ESLint: This is a linting tool for JavaScript/TypeScript that helps you maintain code quality.
Tailwind CSS: Tailwind is a popular utility-first CSS framework. Select "Yes" if you want it integrated from the start.
src/ directory: Selecting "Yes" will create a src/ folder to organize your application code.
App Router: The recommended router for Next.js projects. This should generally be set to "Yes."
Turbopack: A faster bundler and development server for Next.js. Choose "Yes" to use it, or "No" for Webpack.
Import alias: The alias used for importing modules. By default, this is set to @/*, but you can customize it if needed.

After answering these questions, your Next.js project will be created. It may take a few minutes depending on your internet speed and computer performance.

Here’s an example of a basic root layout file (app/layout.tsx):

Breakdown: RootLayout: A functional component that wraps all of your pages. children: Represents the nested content (pages) that will be rendered inside this layout.

  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  );
}

This ensures that the content of your application is rendered inside the body tag. You can customize this layout to include global components like headers, footers, and other elements that should appear across all pages of your application.

Running Your Next.js Project Once your project is set up, you can run it locally by using the following command:

npm run dev

This will start a local development server at http://localhost:3000. You can open this in your browser to view your Next.js application.

You’ve now successfully set up a Next.js project! You can start building your pages, components, and layouts to create a dynamic, production-ready web application.
