In the ever-evolving landscape of web development, Next.js has emerged as a powerhouse, offering a range of technical benefits that cater to the modern developer's needs. With more than 117k stars ⭐️ on GitHub, Next.js is certainly now a framework that is attracting attendtion in the web development world.

Its unique features and capabilities make it an ideal choice for building fast, efficient, and scalable web applications. In this blog, we delve into the technical advantages of using Next.js, exploring how it stands out in the realm of web development frameworks. These are the few top reasons why I use Next.js:

Full-Stack Framework

Traditionally, web development has been divided into two distinct realms: front-end (client-side) and back-end (server-side). Next.js, however, seamlessly integrates these two aspects into a unified development experience. It extends the capabilities of React.js, a front-end library, by introducing server-side functionalities, thus enabling developers to handle both aspects within a single framework.

Server Components

Server Components are a way of executing code on the server side and then sending the rendered output to React on the client side. This will mean all the computation will execute on the server, resulting in faster initial page load. By default, all Next.js components(pages) are Server Components by default. Note that server components don't have access to the client-side interaction, state or manipulate DOM datae.

Server-Side Rendering (SSR)

One of the standout features of Next.js is its built-in support for Server-Side Rendering. SSR is pivotal in delivering content to users faster. By rendering JavaScript content on the server first, Next.js ensures that the initial page load is swift, which significantly improves the performance of web applications. This is especially beneficial for SEO as it helps search engines effectively index the web content, enhancing the visibility and reach of your application.

Static Site Generation (SSG)

Next.js allows developers to pre-render pages at build time. This means that the pages are generated as static HTML, which can be deployed and served directly, leading to faster load times and better performance.

API

API Routes: Next.js enables developers to write server-side code directly within the Next.js application. This allows for the creation of API endpoints within the same project, thus offering a seamless full-stack development experience. You don't need to create node.js server to create a simple API now.

File-based Routing

Next.js uses a file-system-based routing system. Pages are automatically routed based on their file names in the pages directory, simplifying the setup of routes in a web application. You don't need to use react router and configure routes

Automatic Code Splitting

Efficiency is key in web development, and Next.js enhances this through automatic code splitting. It intelligently divides the code into manageable chunks, so users only load what’s necessary for each page. This not only speeds up page load times but also optimizes the overall performance of the application.
