Setting up a new Next.js project

Tutorial 3 of 5

Setting Up a New Next.js Project

1. Introduction

In this tutorial, we'll guide you through setting up a new Next.js project from scratch. Next.js is a React framework that provides features such as server-side rendering and generating static websites for React-based web applications. By the end of this tutorial, you'll have a ready-to-go Next.js project set up on your local machine.

Prerequisites: Basic familiarity with JavaScript and React.

2. Step-by-Step Guide

To create a new Next.js application, we'll go through the following steps:

Install Node.js and npm

Next.js requires Node.js and npm (Node Package Manager) to run. Ensure that you have Node.js (version 10.13 or later) and npm installed on your machine.

Install Next.js, React and React-DOM

Next, we'll install the necessary packages for our project: next, react, and react-dom.

Create a new Next.js application

3. Code Examples

Installing Node.js and npm

Visit the official Node.js website to download and install the appropriate version for your operating system. Once installed, you can check the installed versions of Node.js and npm using your terminal:

node -v
npm -v

Installing Next.js, React and React-DOM

Open your terminal, navigate to your chosen directory, and run the following command to create a new Next.js application:

npx create-next-app@latest nextjs-tutorial

This command creates a new directory called nextjs-tutorial with a brand-new Next.js application inside it. The create-next-app command automatically installs next, react, and react-dom.

Running the Next.js application

Navigate into your new project directory and start the server:

cd nextjs-tutorial
npm run dev

Upon running the server, you should see the following output:

ready - started server on http://localhost:3000

You can now open your web browser and visit http://localhost:3000 to see your new Next.js application in action!

4. Summary

In this tutorial, we went through the steps of installing Node.js and npm, and setting up a new Next.js project. We also learned how to run our Next.js application locally.

For future learning, consider exploring more about Next.js features such as server-side rendering, static site generation, and API routes.

5. Practice Exercises

  1. Exercise: Create another Next.js project, but this time name it nextjs-practice.

Solution: Run npx create-next-app@latest nextjs-practice. Then navigate to the project directory with cd nextjs-practice and start the server with npm run dev.

  1. Exercise: Try stopping and restarting your Next.js server.

Solution: In your terminal, press Ctrl+C to stop the server. Then, restart it by running npm run dev.

Remember, practice is key to mastering any coding skill. Continue experimenting with Next.js and exploring its features. Don't be afraid to make mistakes — they're a part of the learning process!
