What is Next.js?

Next.js is a React-based framework that simplifies building scalable and performant web applications. Its key features include server-side rendering (SSR), automatic code splitting, and a straightforward API for building dynamic web pages. When it comes to e-commerce, these features are particularly advantageous. Additionally, Next.js middleware provides flexibility and extensibility, making handling tasks such as Nauthentication or custom routing easier. To get started, developers can install Next.js using the appropriate command “next.js install”, and for those preferring TypeScript, Next.js TypeScript for a typed development experience.

Key Advantages:

Server-Side Rendering (SSR): Unlike traditional client-side rendering, Server-Side Rendering (SSR) enables your e-commerce website to generate pages on the server and transmit a fully rendered HTML page to the client.This results in faster initial page loads and better search engine optimization (SEO).

Automatic Code Splitting: Next.js optimizes the loading of your application by splitting your code into smaller chunks. This means that only the code required for the current page is loaded, reducing initial loading times and improving overall performance.

Straightforward API: Next.js latest version simplifies complex tasks with its intuitive API structure, allowing developers to concentrate on feature development rather than grappling with configuration complexities.

Next.js and React Native: Next.js React Native can be utilized together for a seamless development experience across web and mobile platforms.

Next.js File Structure: The Next.js framework provides a well-defined Next.js file structure that improves project organization and maintenance, making it easier for developers to navigate and understand the codebase.
