NextJS: Exploring its Benefits and Drawbacks

This article provides an examination of NextJS, a widely utilized JavaScript library. We’ll discuss how it works, its advantages, and potential limitations. Lastly, we’ll show detailed benefits and drawbacks of utilizing this library to enable you to determine if it’s suitable for your project.

What is NextJS?

NextJS is a React-based JavaScript framework created by Vercel (formerly Zeit) that allows developers to create web applications quickly and efficiently.

It provides a powerful server-side rendering system, static site generation capabilities, and an intuitive routing system.

Next also offers a wide range of features, such as code splitting for faster page loads, automatic prefetching for improved performance, and built-in support for CSS-in-JS libraries like Styled Components.

With these features combined, Next.js makes it easy to develop fast and efficient React applications that can be deployed on any hosting platform.

How Does NextJS Work?

At its core, NextJS is based on React and uses the same components and state management concepts as any other React application.

However, it also adds additional features to make development more accessible, such as server-side rendering. This feature enables applications to render pages on the server instead of in the browser, thus increasing speed as users do not have to wait for all JavaScript code to download before being able to view content.

Next also has built-in support for static site generation, which means you can generate HTML files from your content sources (such as Markdown or GraphQL) which helps with SEO optimization and overall performance.

Finally, NextJs has an intuitive routing system, so you can easily set up routes within your application without writing custom code.

According to the 2022 StackOverflow Developer Survey, Next is fifth among the most popular frameworks developers use for front-end development, surpassing React itself.

Advantages of using NextJS

1. Faster development

NextJS provides developers with an out-of-the-box server-side rendering solution that drastically reduces the time it takes to build a web application.

2. Improved SEO

With NextJS, developers can take advantage of automatic code splitting and server-side rendering, which makes it easier for search engine crawlers to index content faster and more accurately.

3. Code Reusability

Developers can easily reuse components across pages with NextJS’s built-in component library, making development more efficient and cost-effective.

4. Hot Reloading

With hot reloading enabled in NextJS, developers don't have to refresh the page every time they make a change manually; their changes are automatically applied without any downtime or disruption to the user experience.

5. Security

By using server-side rendering, Next helps protect sensitive data from being exposed by ensuring that all data is securely stored on the backend rather than on the client side, where malicious actors could access it.

6. Customization

NextJS allows developers to customize their applications with custom routes, plugins, and server-side APIs to create an application that meets their specific needs.

7. Performance

With its advanced caching technology and optimized codebase, NextJS applications run faster than ever with minimal effort on the developer's part.

Disadvantages of using NextJS

1. Limited Browser Support

NextJS only supports modern Chrome, Firefox, Safari, and Edge browsers. This means that users with older browsers may be unable to access your site or app.

2. Limited Customization Options

NextJS is a framework that provides the essential tools to build static websites and applications. If your app renders a lot of dynamic data or has a more complex and interactive UI, there might be better alternatives for your use case.

3. Steep Learning Curve

While NextJS is relatively easy to learn if you already have experience with JavaScript frameworks like React, it can still be quite challenging for beginners unfamiliar with web development concepts and technologies such as HTML, CSS, JavaScript, etc.

How to decide if Next is the right tool for your project

When considering if NextJS is the right tool for your project, you must first consider the size and complexity of your project. If you’re building a static website, or your web app requires managing high loads and maintaining performance, NextJS might be a great solution for you. If your website is highly interactive or your web app has tons of server-side logic, you might want to look elsewhere.

Also, it would be best if you considered how quickly you need to get up and running with your project. With its pre-built components and tools for rapidly creating pages and routes, NextJS can help speed up development time significantly compared to other frameworks.

Finally, consider how much control you need over the design of your website or application. If you’re looking for an easy way to get started with a basic setup that can be extended later on, NextJS can provide a great starting point.


When considering whether or not to use NextJS for a project, it is important to take into account factors such as size/complexity, development time, customization needs, SEO requirements, and performance considerations.

Weighing these factors against each other will help one make an informed decision about whether or not NextJS is suitable for their project.
