Frequently Asked Questions (FAQs)

Next.js is a React framework for building web applications. It provides a set of conventions and tools that develop applications with features like server-side rendering, automatic code splitting, and a simple API for routing. Unlike other frameworks, Next.js simplifies the process of creating universal JavaScript applications with a focus on developer experience and performance.

Next.js enables starting as a static site or single-page application (SPA) that can be optionally upgraded to use features that need a server. Since Next.js supports this static export, it can be deployed and hosted on web servers that serve HTML/CSS/JS.

Next.js helps SEO performance by rendering web pages on the server (server-side) instead of the browser (client-side). Server-side rendering permits search engine crawlers and bots to scan and index web pages, detect metadata, and properly understand the information a website contains static assets.
