If you’re looking to learn how to code in NextJS, you’ve come to the right place. NextJS is an open-source framework for creating server-side rendered (SSR) and statically generated React applications. It is considered to be one of the most popular frameworks for building React applications and is used by many large companies like Twitter, Uber, and Airbnb.

With NextJS, you can easily create dynamic webpages and applications with React. In this article, we will explain what NextJS is, how to set up your environment, and how to code in NextJS. Let’s get started!

What is NextJS?

NextJS is a JavaScript framework that lets you build server-side rendered (SSR) and statically generated React applications. It is an open-source framework created and maintained by the team at Vercel. It enables developers to build React applications quickly and easily.

NextJS also provides an extensive set of features, such as routing, pre-rendering, automatic code splitting, and more. With NextJS, you can easily build server-side rendered applications with React.

Setting up Your Environment

Before you can start coding in NextJS, you will need to set up your environment. The first thing you need to do is install Node.js and npm. Node.js is a JavaScript runtime environment and npm is a JavaScript package manager.

Once you have installed Node.js and npm, you can install the NextJS CLI. This is a command line interface that allows you to quickly create and run NextJS projects. To install the NextJS CLI, run the following command:

npm install -g next

Now that the NextJS CLI is installed, you can create a new project by running the following command:

This will create a new project in the current directory. The next step is to install the dependencies. To do this, run the following command:

npm install

You are now ready to start coding in NextJS.

How to Code in NextJS

Now that you have your environment set up, you can start coding in NextJS. The first thing you need to do is create a page. To create a page, you need to create a JavaScript file in the pages directory.

For example, if you wanted to create a page called “about”, you would create a file called “about.js” in the pages directory. Inside this file, you would write the code for the page.

Next, you need to create a React component. To do this, you need to create a JavaScript file in the components directory.

For example, if you wanted to create a component called “Button”, you would create a file called “Button.js” in the components directory. Inside this file, you would write the code for your component.

Finally, you need to render the page. To do this, you need to import the page and the component into your main file, which is typically called “index.js”.

For example, if you wanted to render the “about” page and the “Button” component, you would add the following code to your “index.js” file:


import About from './pages/about';
import Button from './components/Button';


ReactDOM.render(
,
document.getElementById('root')
);
