What is Next.js?

Next.js is a powerful and versatile framework for building modern web applications using React. Developed by Vercel, it has gained immense popularity in recent years due to its unique features and benefits. At its core, Next.js is designed to simplify the process of building robust web applications by providing a comprehensive toolkit and a clear structure for development.

One of the standout features of Next.js is its ability to handle various rendering methods, including server-side rendering (SSR), static site generation (SSG), and client-side rendering (CSR). SSR and SSG are particularly noteworthy as they contribute to better performance and SEO optimization. SSR involves rendering pages on the server and sending HTML to the client, resulting in faster load times and improved search engine rankings. SSG, on the other hand, allows you to generate static HTML files at build time, making it ideal for content-driven websites.

Next.js is not just another JavaScript framework; it’s a powerful ecosystem that empowers developers to create high-performance web applications with ease. Its ability to seamlessly handle rendering, routing, and code splitting, combined with its extensive plugin system, makes it a top choice for web development in the modern era. Whether you’re a developer looking to enhance your skill set or a business seeking to deliver outstanding web experiences, Next.js is a technology worth exploring and mastering.

Now, your homepage is ready!

5. Running Your Development Server

To see your app in action during development, navigate to your project directory in the terminal and run

This command starts a development server, and you can access your app at http://localhost:3000 in your web browser. You’ll see the “Welcome to My First Next.js App” message.

6. Adding More Pages

Next.js makes it easy to create new pages. For example, to create an “About” page, create a new file called about.js inside the pages directory and add content similar to the homepage

You can now access the About page at http://localhost:3000/about.

7. Deploying Your Next.js App

Once you’ve built your Next.js application, it’s time to deploy it to a web server. Vercel, the company behind Next.js, provides a seamless deployment platform that integrates perfectly with Next.js.
