Next.js

Next.js is a React-based framework for building fast, scalable web applications. It supports server-side rendering (SSR), static site generation (SSG), and client-side rendering (CSR), offering full flexibility for modern web apps.

Installing and Setting Up a Next.js Project

You can create a new Next.js project using npx create-next-app. This sets up a ready-to-use development environment with file-based routing, support for API routes, and fast refresh.

The Rise of Next.js Solutions: Transforming Industries

Next.js uses a file-based routing system—each .js or .tsx file in the pages/ directory automatically becomes a route. Nested folders support dynamic and optional routing out of the box.

Next.js supports SSG for faster performance and better SEO. Using getStaticProps(), you can fetch data at build time and pre-render the page as a static HTML file.

Use getServerSideProps() when you need to fetch data on every request. It enables server-side rendering, which is useful for pages that display dynamic or real-time data.

Client-Side Rendering with useEffect()

Some components or pages fetch data on the client side after rendering. This can be done using React’s useEffect() hook combined with fetch() or Axios for API calls.

Dynamic Routing and URL Parameters

Next.js allows dynamic routes using brackets like [id].js. You can access route parameters using the useRouter() hook, making it ideal for pages like blog posts or product details.

API Routes in Next.js

Next.js includes a backend with serverless functions via the pages/api directory. You can define endpoints like api/user.js to handle backend logic, database calls, or third-party integrations.
