Are you looking for a powerful and flexible framework to build your next web project? If so, you may want to consider Next.js. This React-based framework has gained popularity in recent years thanks to its many advantages, such as server-side rendering, automatic code splitting, and static site generation.

Whether you’re building a simple blog or a complex e-commerce site, Next.js can help you create fast, SEO-friendly, and easy-to-deploy web applications. In this article, we’ll dive into the top advantages of Next.js and how they can benefit your web development projects. So, sit back, relax, and let’s explore the world of Next.js!


One of the most appealing features of Next.js is its file-based routing system. With this approach, you can organize your pages by simply creating a new file in the “pages” directory of your project. Next.js will automatically map each file to a URL path based on its filename.

For example, if you create a file named “about.js” in the “pages” directory, Next.js will generate a route for it at “/about”. If you want to create a nested route, you can simply create a subdirectory within the “pages” directory and place your file inside it. If you create a file named “contact.js” inside a “pages/about” directory, the generated route will be “/about/contact”.

This file-based routing system is not only simple and intuitive, but it also allows for dynamic routing with ease. You can use dynamic parameters in your file names to create dynamic routes that can accept URL parameters. For example, if you create a file named “[slug].js” in the “pages” directory, Next.js will generate a route for it that can accept any value in place of the [slug] parameter. You can then access the parameter inside your page component, to generate dynamic pages. This can be incredibly useful for creating routes that are based on user-generated content or data from a database.

The file-based routing system in Next.js makes it easy to create and manage your web application’s routes. By using a file-based approach, you can keep your code organized, maintainable, and scalable, while also benefiting from the flexibility and power of dynamic routing.


Another benefit of Next.js is the pre-rendering solutions it offers, through server-side rendering (SSR) and static site generation (SSG).

With SSR, Next.js generates the HTML for your pages on the server, before sending them to the client. This means that your users can see the content of your pages more quickly, without having to wait for all of the JavaScript to load. Additionally, search engines can crawl and index the content of your pages more easily, leading to improved SEO.

SSG takes this a step further by generating HTML pages at build time instead of on the server at runtime. This means that the content of your pages is pre-rendered and served from a CDN, which can result in lightning-fast page loads and even better SEO. Plus, since the content is pre-rendered, there’s no need for a server to generate it on the fly, reducing server load and improving scalability. This lets you deploy your Next.js app on any server that can serve up static HTML, such as GitHub pages.

Next.js makes it easy to use either SSR or SSG, depending on your needs. You can use the getStaticProps and the getServerSideProps to use either of these approaches. With SSG, Next.js also supports incremental static generation (ISG), a feature that allows you to update only the pages that have changed, instead of rebuilding the entire site.

Next.js makes it easy to use both of these techniques, giving you the flexibility and control you need to create fast and responsive web applications.

Image Optimization

Loading images can be a significant bottleneck for web performance. Large, uncompressed images can slow down page load times, leading to a poor user experience. Fortunately, Next.js includes a number of features that make it easy to optimize images and improve the performance of your web applications.

First and foremost, Next.js supports automatic image optimization out of the box. When you import an image into your project, Next.js will automatically optimize it by generating multiple versions of the image at different sizes and resolutions. This allows your application to serve the most appropriate image to each user, based on their device and viewport size. Next.js also supports modern image formats such as WebP, which can provide better compression and faster load times compared to older formats like JPEG and PNG.

Next.js also includes features for lazy loading and progressive loading of images. By using the “lazy” attribute on your image components, you can defer the loading of images until they are actually needed. This can significantly reduce the initial page load time, as images below the fold won’t be loaded until the user scrolls down. Progressive loading, on the other hand, allows you to display a low-resolution placeholder image first, then gradually replace it with a higher-resolution image as it loads.

Next.js also includes a feature called the “Image Optimization API”, which allows you to perform on-the-fly image transformations and optimizations. This can be useful if you need to adjust the size, quality, or format of an image on the fly, based on user input or other dynamic factors.


Next.js is owned by Vercel, a company which offers cloud-based deployment solutions. Thanks to this, Vercel have made it incredibly easy to deploy a Next.js app through Vercel.

Vercel automatically detects your Next.js project’s configuration and settings, so you don’t need to manually configure anything to get your site up and running. This includes settings like your Next.js version, dependencies, and build options, all of which are automatically detected and configured by Vercel.

Vercel will then automatically build your Next.js site and deploy it to their global CDN, making it available to users around the world. The entire process usually takes only a few minutes, and you don’t need to worry about any complex build or deployment processes.


Thanks for reading! Next.js is a great framework, which offers out-of-the-box solutions for a lot of the common issues you’ll run into when building a web app. Whether you’re looking to build a simple static website, or a robust web application, Next.js is a great option.
