Next.js is an open-source React framework that simplifies the process of building modern web applications. It provides a set of features out-of-the-box that make it easy to create fast, scalable websites with excellent performance. By supporting static site generation (SSG), server-side rendering (SSR), and incremental static regeneration (ISR), Next.js ensures pages load quickly and perform optimally across different devices and networks.
Core Features:
- Hybrid Static & Server Rendering: Supports both static site generation (SSG) and server-side rendering (SSR), giving developers the flexibility to choose the right rendering method based on the content and use case.
- API Routes: Easily create serverless functions and backend APIs directly within the Next.js app, simplifying full-stack development.
- File-Based Routing: Automatically create routes based on the file structure, reducing the need for manual configuration.
- Image Optimization: Next.js automatically optimizes images for better performance and faster loading times using the built-in
next/imagecomponent. - Fast Refresh: A fast and reliable development experience with real-time updates during development.
- Built-in CSS and Sass Support: Next.js includes support for CSS Modules, global CSS, and Sass without the need for additional configuration.
- Incremental Static Regeneration (ISR): Allows you to update static content on-demand without rebuilding the entire site.
Use Cases:
- E-Commerce Websites: Build fast, SEO-friendly online stores with dynamic product listings and checkout flows.
- Blogs & Documentation Sites: Create high-performance blogs or static sites with fast page loads and easy content updates.
- Corporate Websites: Develop corporate websites or landing pages that deliver high-quality performance and SEO optimization.
- Web Apps with Server-Side Logic: Create React web apps that also require server-side functionality, like personalized user dashboards or data-driven applications.
