React.js vs. Next.js: Which One Should Your Developer Specialize In?

The evolution in the web development landscape is at a breakneck speed and it’s no hidden reality. Choosing the right technology stack becomes crucial especially when you are considering front-end development and there is a list of the top frameworks for front-end development.

Amongst these the 2 frameworks that are constantly dominating the landscape are React.js and Next.js. Both are powerful tools but to understand their nuances is vital when you are considering developing scalable, performant, and user-friendly web applications. The debate of React.js vs. Next.js is not simply about which is inherently better, but more about which one suits better for your specific project needs. As a SaaS company this decision can have a significant bearing on the development speed, performance, SEO, and overall cost.

In this article we will dive deep into each framework to explore the differences and help you determine which specialization will be more beneficial for your project.

What is React.js?

React.js is regarded as a declarative, efficient, and flexible JavaScript library for developing user interfaces. It lets you build complex user interfaces from small and isolated code pieces called “components”. It’s not a full-fledged framework but a library that is solely focused on the view layer of an application.

Core features and functionalities

React’s core lies in its component-based architecture, virtual DOM, and JSX syntax. The component-based architecture allows developers to break down UIs into reusable components, promoting code reusability and maintenance. The virtual DOM helps in performance optimization by minimizing direct manipulations to the real DOM.

Additionally, JSX serves as a valuable extension to JavaScript allowing developers to write HTML-like code within JavaScript. This makes UI development more intuitive with faster rendering.

Use cases and industries where React.js excels

The need to hire dedicated React.js developers is prominent across a vast spectrum of industries from e-commerce to social media and content management systems. The component-based architecture and fast rendering potential make it an ideal pick for interactive and dynamic UI development. It’s a well-suited fit for single-page applications where performance and user experience hold an upper hand.

Companies using React.js

Several reputed companies have and are still leveraging React.js to power their web applications. Facebook, Instagram, Airbnb, and Yahoo are just a few examples. These companies trust React’s scalability, performance, and flexibility in rendering exceptional user experiences to millions of users globally.

It should come as no surprise that Facebook, the creator of React, utilizes it extensively across its platform.

What is Next.js?

Next.js is an open-source React framework enabling functionalities such as server-side rendering and static website generation for React-based web applications. It’s built on top of Node.js and allows React-based web applications to be rendered from the server-side instead of rendering all content in the browser.

Core features and functionalities

Next.js enhances React with server-side rendering (SSR), static site generation (SSG), file-system routing, and API routes. SSR improves SEO and initial load time by rendering pages on the server before sending them to the client. SSG allows you to pre-render the pages at build time, resulting in an extremely fast loading time. The file-system routing system simplifies the route creation, while API routes enable you to build backend functionalities directly within your Next.js application.

Advantages over traditional React.js applications

Next.js offers several advantages over traditional React.js applications. Some of these include:

Server side rendering significantly improves SEO by making it easier for search engines to crawl and index your website.
Static site generation helps deliver unmatched performance by pre-rendering ages at build time.
Built-in routing simplifies the development process and eliminates the need for external routing libraries.
Companies using Next.js

Several companies utilize Next.js, including Netflix, TikTok, Starbucks, and Uber. These companies leverage the performance and SEO potential of Next.js to power its landing pages, while TikTok uses it to improve its website performance and SEO.

Key Differences Between React.js and Next.js

The core difference between React.js vs. Next.js lies in their nature. React is a library focused on UI rendering, while Next.js serves as a full-fledged framework built upon React, offering features like routing, server-side rendering, and API handling out-of-the-box.

Let’s compare them on the following grounds:

Focus Area	React.js	Next.js
Architecture and Framework Comparison	It’s primarily a library that is focused on UI components. When you hire dedicated React.js developers they need to choose and integrate additional libraries for routing and data fetching.	It’s a framework that is built on React, providing built-in solutions for routing, API endpoints, and data fetching. It offers a more structured and opinionated development approach.
Performance differences	It can result in slower initial load times due to client-side rendering, where the browser downloads and executes all JavaScript before rendering the UI.	On grounds of React.js vs. Next.js performance, the latter holds prominence. Thanks for the server-side rendering and static site generation resulting in agile load time. However, subsequent client-side interactions can be slightly slower.
SEO capabilities: Client-side vs. Server-side rendering	Significant efforts and configuration is required to optimize for search engines. Search engines often face challenges in properly indexing content that is rendered on the client-side.	It’s optimized for SEO out-of-the-box because content is rendered on the server or during build time. This makes it readily indexable by search engines which is yet crucial for your SaaS company.
Development complexity and learning curve	It has a low learning curve initially due to small scope.	Higher learning curve due to the framework’s more comprehensive feature set and conventions.
Scalability and maintenance	Highly scalable when following best practices for component design and state management. Well-maintained with a large and active community.	Highly scalable with features like API routes and serverless functions. Well-maintained with a growing community, benefiting from Vercel’s support.
