Study Notes


Next.js is a popular React framework, known for its capabilities in static site generation (SSG), server-side rendering (SSR), and advanced data fetching. This article will delve deeper into these aspects, explaining what each term means and how Next.js utilizes them to build modern web applications.


Routing refers to navigating between different parts of a web application, moving from one screen or view to another based on user interactions or system events. Next.js provides a simple and intuitive approach to managing navigation, allowing developers to define routes for their components. Users can navigate between different screens within a single application, and the system will handle the appropriate transitions.

API Routes

API routes, which are part of Next.js's endpoints feature, enable developers to serve HTTP requests that don't require static assets, such as JSON data or responses for RESTful APIs. These routes can receive parameters, query strings, and handle authentication, offering more control over the behavior of server-side functions.

Server-Side Rendering (SSR)

Server-side rendering is a process by which HTML rendering takes place on the server rather than on the client's browser, resulting in improved performance, accessibility, and SEO optimization. Next.js employs a hybrid model that combines both static site generation and server-side rendering, ensuring optimal loading speeds, enhanced interactivity, and efficient resource usage.

Static Site Generation (SSG)

Static site generation involves pre-building the site content during development, serving fully formed HTML, CSS, and JavaScript files. This eliminates the reliance on server-side processing for each request, leading to faster page loads and better scalability. Next.js allows developers to pre-render components with static data, enhancing the SEO aspects and overall site speed.

Data Fetching

Next.js offers various approaches for fetching data within React applications. One such method is server-side data fetching using getServerSideProps, which fetches data on the server before rendering the page. Another approach is client-side data fetching using useEffect, which fetches data on the client-side after the component has rendered. Additionally, Next.js supports server-side data fetching and hydration, ensuring a seamless transition from server-side rendering to client-side interactivity.

In conclusion, Next.js is a versatile and powerful framework that offers a wide range of features for building modern web applications. Its approach to data fetching, server-side rendering, and static site generation make it an excellent choice for developers who prioritize performance, SEO optimization, and a seamless user experience.

Explore the key features of Next.js including routing, API routes, server-side rendering (SSR), static site generation (SSG), and data fetching methods. Learn how Next.js combines static site generation and server-side rendering for optimal performance and SEO optimization.
