Next.js is a React-based framework for building web applications, and it can be used to generate static sites, server-rendered sites, or client-side rendered sites.
Next.js provides two main approaches for generating pages: server-side rendering (SSR) and static site generation (SSG).
In SSR, the server generates the HTML for each page on the fly, in response to user requests. With Next.js, you can use server-side rendering to generate the initial HTML for each page and then send it to the client, where it can be hydrated into a fully functional React app. This approach can be useful for sites that require dynamic content, like e-commerce sites, where the content changes frequently.
In SSG, the HTML for each page is generated at build time, and the resulting files are then served to users. With Next.js, you can use SSG to generate a completely static site, which can be very fast and easy to cache. This approach can be useful for sites that don’t require dynamic content, like blogs, portfolios, or marketing sites.
In summary, Next.js can be used for both SSR and SSG, depending on your needs. It’s a flexible framework that can be used to build a wide range of web applications.
