How to Create Next App

Updated 10 May 2022

In this blog, we will discuss how to create next app?

Next.js is an open-source JavaScript framework created by Vercel to enhance React applications with features such as Server-Side Rendering and Static Site Generation.

Next.js is a web framework that sits on top of React taking the power of React to another level. With it, we get additional data fetching utilities and site compilation that providers optimized builds with logical ways of managing our data.

Traditionally, React is used to create Single-Page Applications (SPAs) whose contents are rendered on the client-side. Next.js extends this by allowing developers to create applications that can perform server-side actions and pre-fetch routes and has support for TypeScript. On top of that – it doesn’t require any extra configuration by default!

It was actually initially a Next community project, but the team at Next felt that it was very important to be a major part of the first channels through which developers get to experience Next, so they got the maintainers to transfer ownership to them.

Getting started with Create Next App

Now, that we have some relevant context about Create Next 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

After the installation:

  • Run npm run dev or yarn dev or pnpm dev to start the development server on http://localhost:3000
  • Visit http://localhost:3000 to view your application
  • Edit pages/index.js and see the updated result in your browser.

Even without any arguments at all, you get a whole interactive experience where you are guided through every step to set up a new project. This can be the turning point that makes a new user into a returning one, and Next has covered that really well.

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 as one second. 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 Server-Side Rendering Framework.

Next.js allows us to render our content in different ways, depending on our application’s use case. These include pre-rendering with Server-side Rendering or Static Generation, and updating or creating content at runtime with Incremental Static Regeneration.
