NextJS 13 Latest Features

It's been just six years since the release of NextJS. But, the JavaScript framework has made strides in the web development world. As it goes all out to simplify and speed up dynamic websites, NextJS has recently launched its 13th version.

Here, we'll look at what NextJS is, the framework’s applications, and its pros and cons. We'll also answer the most asked questions about this technology. Finally, we'll review its latest updates. Are you ready?

What is NextJS?

Launched in 2016 by Vercel, NextJS is a React framework for web app building. It's recognizable for being user-friendly and speeding up development processes. NextJS tackles the tooling and configuration the React library needs. Also, it has some extra features.

What is NextJS used for?

NextJS can build many different digital products. These include webpages and Jamstack websites. Further, it applies to interactive user interfaces, e-commerce websites, and dashboards. While it's possible to make SPAs with NextJS, it’s often chosen to avoid SPAs altogether. Frequently, this happens due to their slow First Contentful Paint and SEO performance.

Many ventures in various industries use NextJS in their projects. These fields include tech, e-commerce, marketing, news, and finance. Along the companies using it, there is TikTok, Hulu, Twitch, and Starbucks.

How does NextJS work?

How does NextJS work?

React apps are usually client-side. This approach has a couple of downsides. Often, content needs to be reliably indexed by search engines and social media bots. Plus, it takes longer to get to the First Contentful Paint. NextJS makes it possible to render the content in advance in a server, which solves these issues. NextJS also provides its router and allows you to render your pages at build time with pre-rendering.

Pre-rendering can take the form of static generation for sites that don’t change often. Also, it can do server-side rendering for websites where data changes regularly. There is also incremental static regeneration. This procedure is a midpoint between static generation and server-side rendering. You can take a deeper look at how this works in this video. Let’s look at some of the concepts we’ve just discussed.

NextJS' Pages

NextJS default folder structure includes the pages, public, and styles folders. Pages are React components, and each file in this folder corresponds to a web page. NextJS includes pre-created custom pages. You’ll be able to spot them as they have easy prefixes with underscores.


Pre-rendering happens when external data is fetched. Also, when the React components translate into HTML on the server. All this occurs before the user receives the page content. NextJS renders every page in advance on the server. Yet, it's possible to opt-out of pre-rendering using the client-side data fetching options. The main difference is that initial rendering takes place on the user's device. NextJS pre-rendering applies to Static Generation (SG) and Server-Side Rendering (SSR). These two pre-rendering forms fetch data in different ways. Let's take a look at them!

Server-Side Rendering

Here, the HTML is generated on the server for each request.

Static Generation

Static generation does happen on the server. But, more specifically, only once at build time. This procedure means the HTML is ready to be sent without further processing. This method translates into a faster loading time. You can find more about NextJS rendering on this page.

Incremental Static Regeneration

Incremental Static Regeneration (ISR) updates or creates content at runtime. With it, you don’t have to rebuild the site with every update. You can take a look at how this works here.

Is NextJS worth using?

The advantages of using NextJS for your next web project outweigh the disadvantages. You’ll find a list of pros and cons below that prove our point.

Pros of NextJS

Setup and Performance

You only need to download the NodeJS environment and run some scripts to start with NextJS. It’s also available for every platform (Windows, Mac, and Linux). Moreover, code-splitting and client-side navigation mean NextJS has outstanding performance.

SEO Purposes

Static pages, like those generated with NextJS, are easier to index for SEO purposes. They also rank higher than dynamically generated web pages. In turn, NextJS sites will drive more traffic.


Websites and apps created with NextJS are available on any device. This availability encloses Windows, Mac, and Linux operating systems. Plus, it applies to iOS and Android for mobile.

Fast Development

NextJS includes various ready-to-use components that reduce time-to-market.

Hot Module Reloading

With HMR, changes can reload in an application while running without losing the state.

Great Support

The popularity of NextJS has been overgrowing. It is in 9th place among the most popular web techs for developers. Its flourishing community means there are more and more contributors to the framework. This backing translates into resources for any issue.

Cons of NextJS

Maintenance Costs

Although NextJS is highly flexible, it requires continuous management. You’ll need a dedicated developer to install changes and updates to your site or app.

Debugging and Errors

NextJS has a unique way of handling errors that may make them difficult to solve.

No State Manager

NextJS does not have an in-built state manager. But you can add one, such as Redux or MobX.

Lack of Plugins

NextJS lacks the vast array of other frameworks' easy-to-adapt plugins.

NextJS' Frequent Questions

We’ve discussed what NextJS is and what it’s used for. Also, we say its pros and cons. But there are a few related questions that often come up. We’ll discuss those in this section.

Is NextJS open source?

Yes, NextJS is open-source and free to use under the MIT license.

Is NextJS front-end or back-end?

NextJS is technically a front-end framework. But, it has included some back-end features over the years. These include API routes and middleware.

Does NextJS use Express?

Express is a web framework designed for NodeJS. NextJS does not need to use Express, but the combination has some benefits. One of the main benefits is enabling an existing Express API server. Also, there's running Express middleware and adding WebSocket functionality. You can find out how to integrate the two tools in this article.

When Should I not use NextJS?

NextJS is a great tool, but there are some situations in which it is not recommended. One of these is if you have an existing codebase and are not ready for major refactoring and testing. Another reason not to use NextJS is if you are a fan of CDNs, as these are tricky to use with NextJS. You should also avoid the framework if you work with a conventional single HTML file. You can find more information about when not to use NextJS here.

NextJS vs. NodeJS

NodeJS is a JavaScript runtime environment used to build scalable network apps. In contrast, NextJS is a JavaScript framework used to build websites and web apps. What is the difference between the two? A runtime environment executes commands; it processes code to produce results. Meanwhile, a framework focuses on how you should write code. It makes the code more streamlined and standardized.

Like NextJS, NodeJS is open-source, cross-platform, fast, and scalable. NodeJS offers improved developer productivity and satisfaction and reduced development costs. It also provides an easy learning curve and a large community. Rather than opposites, NextJS and NodeJS are complementary. You can use NodeJS to build the back end of a NextJS app, as you can see here. As seen here, you can also use a custom NodeJS server in a NextJS app.

NextJS vs. React

React is a front-end JS library used to build user interfaces (UIs) for the web. And, as we’ve established, NextJS is a JS framework. Yet, more specifically, it's a React framework. As a result, not only NextJS and React can work together. You need React to use NextJS.

Thus, the question is not how the two tools compare but whether NextJS is the best tool for your React project. We can say that React and NextJS complement each other. While React adds a large community, NextJS brings SEO benefits and fast performance. You can learn more about the React library in this article.
