Once we have this minimal set of tools, we can install Next JS using npm or Yarn.
In this section, a simple Hello World project will be created using the console and a code editor.
Step #1 - Create project directory
Step #2 - Execute npm init to generate package.json for our project with minimal information:
During the process, we can use the defaults for all questions. In the end, npm will ask to confirm the information and the file is saved.
Step #3 - Install dependencies
Step #4 - Create a simple page
Next JS expects the React content in the pages directory and our simple page is saved in this location.
Step #5 - Added scripts to the package.json file
Once we have saved the file, we can start this simple open-page Next JS project:
The command will print a few messages in the terminal and serve the page on port 3000
By visiting the project in the browser, we should see our Hello World message:
A Real Next JS Sample
Obviously, the above sample is pretty simple and minimal, just to make curious the audience. In this section is mentioned a production-ready Next JS sample released by Creative-Tim as an open-source project.
Next JS Material Kit is a Free Material Design Kit made for NextJS, React, and Material-UI. Next JS Material Kit is built with over 100 individual frontend elements, giving you the freedom of choosing and combining. All components can take variations in color, which you can easily modify using SASS and JSS (inside JS files) files and classes.
How to build the project
Step #2 - Change the current directory inside the project and install dependencies
Once the depenedencies are installed, we can start the project in development mode:
If all goes well, we should see the project running in the browser on port 3000 (the default port):
Being a flexible framework, NextJS allows us to define special page handlers used globally across the project:
Custom "Document" used to augment your application's
<html>and<body>tags.
To override the default Document, and define properties like lang we need to create the file ./pages/_document.js
App.jsallows us to wrap ALL pages in a special wrapper and use a persistent layout across all pages.
Using this special page, we can achieve with ease a few useful things:
Layout persistence between page changes
Use a global CSS
Preserve the app state when navigating app pages
Custom error pages - 404/500 Error Handlers
Next JS provides a 404 error page by default but in the same time allows us to overwrite it via pages/404.js file. The same thing we can do to handle with a custom page the 500 Error case.

To start using Next JS a should be already installed with some of the tools:
A modern editor - or
- used in -based products and tools
- a popular package manager for NodeJS (better than )
- a command-line tool used to download sources from
The source code can be downloaded from Github:
