Next JS vs React

What is React

React is a JavaScript library for building interactive user interfaces.

By user interfaces (UI), we mean the elements that users see and interact with on-screen.

By library, we mean React provides helpful functions (APIs) to build UI, but leaves it up to the developer where to use those functions in their application.

Part of React’s success is that it is relatively unopinionated about the other aspects of building applications. This has resulted in a flourishing ecosystem of third-party tools and solutions, including Next.js.

It also means, however, that building a complete React application from the ground up requires some effort. Developers need to spend time configuring tools and reinventing solutions for common application requirements.

What is Next.js?

Next.js is a React framework that gives you building blocks to create web applications.

By framework, we mean Next.js handles the tooling and configuration needed for React, and provides additional structure, features, and optimizations for your application.

You can use React to build your UI, then incrementally adopt Next.js features to solve common application requirements such as routing, data fetching, and caching – all while improving the developer and end-user experience.

Whether you’re an individual developer or part of a larger team, you can use React and Next.js to build fully interactive, highly dynamic, and performant web applications.

Features of Next.js

The following features make Nextjs a cutting-edge tool for developers:

  • File system routing
  • Server Side rendering
  • Static site generator
  • Image optimization
  • Automatic code splitting
  • Typescripttwhen to use next js support
  • API route
What is Next.js Used For?

Next.js is well-suited for various types of web applications, and its features make it particularly useful for certain scenarios. Here are some types of applications for which Next.js is a good fit:

  • Static Websites and Blogs:
    • js can generate static websites, which is beneficial for sites that don’t require dynamic content on every request. This is great for blogs, company websites, and portfolios.
  • Server-Side Rendered (SSR) Applications:
    • Applications that benefit from server-side rendering, where initial page content is generated on the server and then sent to the client, can use Next.js to improve performance, SEO, and provide a better user experience.
  • E-commerce Websites:
    • E-commerce websites often have dynamic content and require good SEO. With Next.js, you can implement server-side rendering for product pages, category pages, and other dynamic content, improving the overall user experience and search engine visibility.
  • Content-driven Websites:
    • Websites with a heavy focus on content, such as news sites, can benefit from the SEO advantages provided by server-side rendering. Next.js makes it easier to implement dynamic content while maintaining good performance.
  • Progressive Web Apps (PWAs):
    • js can be used to build Progressive Web Apps, which are web applications that provide a native app-like experience. This includes features like offline access, push notifications, and a responsive design.
  • Enterprise Applications:
    • js can be suitable for building enterprise-level applications, especially when there’s a need for server-side rendering, efficient page routing, and maintaining a clean and modular codebase.
  • Prototyping and MVPs:
    • For quickly building prototypes or minimum viable products (MVPs), Next.js can be a good choice due to its convention-based approach, which helps in rapid development.
  • Hybrid Applications:
    • Applications that require a mix of static and dynamic content can benefit from Next.js’s ability to handle both static site generation and server-side rendering.

It’s important to note that the choice of framework depends on various factors, including the specific requirements of the project, the development team’s expertise, and the desired performance characteristics. Next.js provides a good balance between simplicity and powerful features, making it suitable for a wide range of applications.

Advantages of Next.js

What reasons are there to use Next.js for your next project or even considering to learn it?

Speed

Next.js supports static site generation and server-side rendering. Static generation is fast because all web application pages have been pre-rendered, cached, and served over a CDN.

Server-side rendering is fast as the server handling the request, but on request, these pages are already built on the server rather than being built on the client side.

Less Setup

In Next.js, most features you get come with zero configuration as they are inbuilt. For example, the page routing is where you do not need to write any code to create a route in your app.

Easily Create Your Own Back-End

Easily create your custom back-end functionalities to power your own front-end. This does not affect the size bundle of your client-side application.

Built-In CSS Support

One of the key features of Next.js is its built-in CSS support. This means that developers can include CSS Stylesheets within their Next.js projects without needing to use any additional libraries or tooling. This can be particularly useful for small projects where adding a CSS preprocessor would add unnecessary complexity.

In addition, the built-in CSS support means that developers can take advantage of features such as server-side rendering and code splitting without having to worry about whether their CSS will be properly processed.

Disadvantages of Next.js

Next.js is a great framework with rapid growth but has downsides to it. Let’s take a look at it below:

Development and Maintenance

Building a Next.js application requires a significant upfront investment. Not only do you need developers who are familiar with Nextjs, but you also need to dedicate ongoing resources to maintaining the application.

Routing System

Next.js’s routing system is helpful, but it comes at a cost. By tightly coupling your routing logic to your pages, you make your pages heavier and more difficult to maintain. This can be a serious problem if you need to change your routes frequently or want to reuse your routing logic in other parts of your application.
