Next.js is a robust open-source React framework used in web application development. It was introduced in 2016 by Vercel, formerly known as ZEIT, and has since gained widespread adoption in the web development community.

At its core, Next.js focuses on enhancing the performance, scalability, and SEO-friendliness of React applications. It achieves this by seamlessly integrating server-side rendering (SSR) and static site generation (SSG) capabilities, allowing developers to pre-render web pages on the server side for optimized performance.

Next.js also provides features like dynamic routing and API routes, making creating dynamic and interactive web applications more accessible. Dynamic routing allows for flexible URL structures, while API routes enable developers to build serverless API endpoints within their Next.js applications.

The framework has robust data-fetching capabilities. With Next.js, developers can implement various data fetching techniques, including server-side data fetching with getServerSideProps and static data fetching with getStaticProps and getStaticPaths.

Next.js seamlessly integrates with the broader React ecosystem. Developers can leverage tools from the React ecosystem, such as Redux, GraphQL, and TypeScript, allowing developers to leverage their existing knowledge and workflows.

Key features and uses of Next.js

Next.js, a versatile framework built on React, offers a range of powerful features and capabilities that empower developers to create high-performance and scalable web applications. In this section, we will explore the critical elements of Next.js and how they’re applied:

Server-side rendering

Server-side rendering (SSR) is a technique that allows web applications to generate and deliver fully rendered HTML content on the server before sending it to the client. This approach differs from client-side rendering, where the browser downloads a minimal HTML skeleton and relies on JavaScript to fetch data and render the page.

When a user requests a page from a Next.js application, the server processes the request and generates the HTML content for that page. The user receives a fully rendered HTML page from the server rather than a minimal HTML shell requiring further rendering on the client side. By performing the rendering on the server, SSR improves the initial page load time and provides an enhanced user experience from the start.

Next’s SSR also improves a site’s Search Engine Optimization (SEO), given search engines typically have difficulty parsing and indexing JavaScript-heavy applications that rely heavily on client-side rendering. With SSR, Next.js provides search engines with pre-rendered HTML content. The pre-rendered content is more straightforward to crawl and index. The application pages subsequently have better visibility in search engine results, crucial for driving organic traffic to websites and applications.

SSR also facilitates seamless integration with existing server-side APIs and backend systems. Therefore, Next.js applications can interact with server-side resources, such as databases, external APIs, and authentication systems, on behalf of the user. You can create dynamic and personalized experiences for your users while benefiting from the simplicity and reactivity of React on the client side.

Static site generation

Next’s Static Site Generation (SSG) is a powerful feature that allows developers to pre-generate static HTML files for each web application page during the build process. The framework analyzes the application’s pages and components at build time. It then generates the corresponding HTML files, which can be served directly to the client without needing server-side rendering on each request.

Next.js fetches the necessary data for each page, generates the HTML content, and stores it as static files. All these steps occur during the build process. You can then deploy these static files to a content delivery network (CDN) or a static file hosting service. When a user visits a page, the static HTML file is delivered from the CDN, resulting in faster page loads and improved performance — the downstream benefits of improved SEO and user experience automatically follow.

For high-demand scenarios where scalability is essential, SSG can be critical. The pre-rendered static files reduce the server load, allowing higher traffic volumes without performance degradation.


Routing is a fundamental aspect of web development that determines how an application handles and responds to different URLs or paths. In Next.js, routing is a critical feature that enables developers to define and manage their applications’ navigation and page rendering logic.

The framework’s routing system works in three ways:

Dynamic routing

In traditional web development, when handling dynamic content, developers often create separate pages or components to cater to each unique value. For example, if you have a blog application and want to display individual blog posts, you might create separate pages for each post. As the number of dynamic values increases, it becomes cumbersome, resulting in many files to manage.

Next.js dynamic routing simplifies the development process by eliminating the need to define separate pages for each unique value. Instead, a single-page file with a dynamic route can handle multiple variations based on the dynamic parameter, saving time and effort by reducing code duplication and maintenance overhead.

With Next.js dynamic routing, you can create a single page file that handles all dynamic content variations using brackets ([ ]) in the page file name. For example, a file named [id].js in the pages directory will create a dynamic route that matches URLs like /post/1 and /post/2, where the id parameter can vary. When a user visits /blog/post-1, Next.js captures post-1 as the dynamic parameter and passes it to the page component. You can then fetch the corresponding blog post data based on this parameter and render the content dynamically.

Needing only to manage and update a single file means significantly reduced code duplication and maintenance overhead. Win!

Nested routing

Nested routing allows developers to create hierarchical page structures. This routing system automatically reflects the URL structure by placing page files within nested directories inside the pages directory. For example, a file named pages/products/index.js will create a nested route for the /products URL.

Index routing

Index routing in Next.js refers to the default route configuration for a directory or folder within the pages directory. It allows you to render a default page when a user visits the root URL or a URL corresponding to that directory. When you create an index.js file within a directory inside the pages directory, it acts as the default route for that directory. For example, if you have a directory named blog and place an index.js file inside it, the blog/index.js file will render when a user visits the /blog URL.

The index route acts as the entry point for a specific directory, serving as the default page to be displayed. It provides a convenient way to organize and structure your application’s pages, especially when dealing with nested routes or when you want to define a default view for a specific directory.

Data fetching

Next.js offers three primary methods for data fetching - getStaticProps, getServerSideProps, and API routes. These allow developers to retrieve data from APIs, databases, or other sources and incorporate it into their applications. Both server-side rendering (SSR) and static site generation (SSG) scenarios allow for data fetching, enabling developers to optimize performance and provide dynamic content.

Use the getStaticProps function when using static site generation in Next.js. During the build process, Next.js executes getStaticProps and fetches data, generating static HTML files with the fetched data. These static files are then served to users, resulting in fast and efficient content delivery. This approach is ideal for fetching data that does not change frequently and can be pre-rendered at build time.

Use the getServerSideProps function when using server-side rendering in Next.js. When a page is requested, Next.js executes getServerSideProps on the server and fetches data before rendering the page. The fetched data is then passed as properties to the page component, ensuring the page renders with the necessary data. Use cases for this include fetching data that requires authentication, access to server-side resources, or frequently changing data.

Next.js allows developers to create serverless API routes within their application using the pages/api directory. These API routes can handle various HTTP methods like GET, POST, PUT, DELETE, etc., and execution occurs on the server. API routes provide a convenient way to build backend functionality directly within the Next.js application, enabling seamless integration between client-side and server-side code.

Next.js and the React ecosystem

Next.js is built on React, benefiting from React’s robust component-based architecture and rendering capabilities. React is a JavaScript library for building user interfaces, while Next.js is a framework that enhances React by providing additional features and optimizations. As such, Next.js integrates smoothly with popular state management libraries like Redux. Redux provides a predictable state container for managing complex application states. By combining Redux with Next.js, developers can efficiently manage and synchronize the state between client-side and server-side rendering. Next.js’s data fetching strategies, such as getServerSideProps or getStaticProps, can be used with Redux to fetch and manage data from APIs or external sources.

Next.js also integrates well with GraphQL, a query language for APIs. Developers can use libraries like Apollo Client or Relay to connect their Next.js applications to GraphQL APIs. Next.js leverages the power of GraphQL by providing support for efficient data fetching and caching, ensuring optimal performance and minimizing unnecessary network requests. This integration allows developers to use GraphQL’s flexibility and declarative nature within their Next.js projects.

Next.js and Jamstack: Empowering Modern Web Development

Jamstack (JavaScript, APIs, and Markup) has emerged as a popular architecture for modern web applications. It emphasizes performance, scalability, and simplicity by leveraging static site generation, client-side JavaScript, and serverless functions. Next.js, with its powerful features and capabilities, aligns seamlessly with the Jamstack philosophy, making it a preferred choice for developers embracing this approach.

Static Site Generation (SSG) and Jamstack

Next.js’s support for static site generation aligns perfectly with the Jamstack approach. By pre-rendering HTML at build time, Next.js generates static files that a content delivery network (CDN) can cache and serve. The result is fast and scalable content delivery, minimized server load, and reduced infrastructure complexity. Static site generation ensures optimal performance, as users receive pre-rendered HTML with minimal JavaScript execution, resulting in near-instantaneous page loads.

Client-side JavaScript and Jamstack

With Next.js, you can incorporate client-side JavaScript to enhance interactivity and dynamic functionality. Developers can build rich user interfaces using React components and leverage client-side JavaScript frameworks or libraries. This approach offloads certain operations to the client’s browser, reducing server load and improving overall application performance. This combination of static site generation with client-side JavaScript provides a powerful balance between performance and interactivity in Jamstack applications.

Serverless Functions and Jamstack

Next.js’s API routes enable the creation of serverless functions within the application, aligning with the Jamstack principle of decoupling backend logic from the front end. With API routes, developers can build custom serverless functions to handle HTTP requests, process data, and interact with external services or databases. This approach fosters scalability, as the serverless functions automatically scale based on demand, ensuring efficient handling of high traffic volumes. Next.js seamlessly integrates serverless functions with the rest of the application, offering a unified development experience within the Jamstack architecture.

Continuous deployment and Jamstack

Next.js facilitates continuous deployment, one of the cornerstones of the Jamstack approach. With Next.js, developers can easily integrate their applications with various deployment platforms, such as Vercel (formerly ZEIT Now), Netlify, or AWS Amplify. These platforms provide automated build and deployment processes, enabling rapid iteration and easy rollbacks. Continuous deployment ensures that code, content, or configuration changes are quickly propagated to the live application, promoting efficient development workflows and fast time-to-market.

Scalability and security in Jamstack

With its support for static site generation and serverless functions, Next.js enhances scalability and security within the Jamstack architecture. Static files and CDN caching ensure Next.js applications can handle high traffic volumes without sacrificing performance. Additionally, serverless functions offer inherent scalability, automatically scaling resources based on demand. The Jamstack architecture, combined with Next.js, improves security by minimizing attack surfaces, reducing the risk of server-side vulnerabilities, and enhancing data privacy.
