Next.Js Tutorial with Examples

Next.js is a popular React framework for building server-side rendered (SSR) web applications. It provides a set of tools and conventions to make it easier to build production-ready applications with React.

Learn Next.Js Tutorial with Examples

Here are some key features of Next.js:

1. Server-side rendering: Next.js allows you to render your React components on the server before sending them to the client. This improves performance and helps with search engine optimization (SEO).
2. Automatic code splitting: Next.js automatically splits your JavaScript code into smaller chunks, which are loaded only when they are needed. This improves performance and reduces the time it takes to load your application.
3. Static site generation: Next.js allows you to generate a static version of your site at build time. This means that you can host your site on a static hosting provider like Netlify or GitHub Pages, which is often cheaper and faster than a traditional server.
4. Built-in CSS support: Next.js supports CSS modules out of the box, which makes it easy to write scoped CSS that only affects specific components.
5. API routes: Next.js allows you to define API routes as serverless functions. This makes it easy to build backend functionality without having to set up a separate server.

How to Create NextJs App:

To get started with Next.js, you’ll need to have Node.js installed on your machine. You can create a new Next.js app using the command line tool called “create-next-app”. Here’s how you can create a new app:

1. Open a terminal window and navigate to the directory where you want to create your app.
2. Run the following command to create a new Next.js app:

npx create-next-app my-app

3. This will create a new directory called “my-app” with all the necessary files and dependencies to run a Next.js app.
4. You can start the app by running the following command:

cd my-app
npm run dev

This will start a development server and open your app in a browser window. You can start building your app by editing the files in the “pages” directory, which contain the React components that will be rendered on the server.

That’s a very brief introduction to Next.js, but I hope it helps you get started!
