How to create a Next.js App

Next.js is an open-source JavaScript framework by Vercel that enhances React apps with features like server-side rendering (SSR), static site generation (SSG) and optimized performance for production.

React is commonly used for Single-Page Web Applications with client-side rendering. Next.js enhances this by adding server-side rendering, route pre-fetching, TypeScript support and zero-config setup.

System Requirements

• NodeJs 18.17 OR above
• MacOS, Windows (including WSL), and Linux are supported

Getting started with Create Next App

Now, that we have some relevant context about creating a Next.js app, let’s get started by installing it.

Installation and Setup

To create a Next js app in the easiest way, open your terminal, cd into the directory you’d like to create the app in, and run the following command:

npx create-next-app@latest
# or
yarn create next-app
# or
pnpm create next-app

It will prompt you with following questions in the command line, then proceed to create your Next.js app. After the installation is complete, we will verify that the app is working correctly.

create-next-app@14.2.13
Ok to proceed? (y) y

What is your project named? › my-next-app

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 to use src/ directory? › No / Yes

Would you like to use App Router? (recommended) › No / Yes

Would you like to customize the default import alias (@/*)? › No / Yes

After the installation:

Run the below command to start the development server:

npm run dev
# or
yarn dev
#or
pnpm dev

Visit http://localhost:3000 to view your application

You can edit either src/app/page.tsx or src/pages/index.tsx, depending on your selection for App Router, and instantly see the updated result in your browser.

Now that we’ve created a Next.js app, we can integrate powerful tools to set up NextJs project scalable, team-friendly for efficient collaboration and development.

Why use Create Next App?

create-next-app allows us to create a new Next.js app within seconds. It is officially maintained by the creators of Next.js, and includes a number of benefits:

• Interactive Experience: Running npx create-next-app@latest (with no arguments) launches an interactive experience that guides you through setting up a project.
• Zero Dependencies: Initializing a project is as quick. Create Next App has zero dependencies.
• Offline Support: Create Next App will automatically detect if you’re offline and bootstrap your project using your local package cache.
• Support for Examples: Create Next App can bootstrap your application using an example from the Next.js examples collection (e.g. npx create-next-app --example api-routes).
• Tested: The package is part of the Next.js monorepo and tested using the same integration test suite as Next.js itself, ensuring it works as expected with every release.

Data fetching methods in Next.js

Next.js provides various ways to fetch data from an API or any other source. Next.js is well known to be a Full-Stack Framework.

It lets us render content in various ways, like pre-rendering with Server-side Rendering or Static Generation, and updating or creating content at runtime using Incremental Static Regeneration.
