Static site generation (SSG) : Omnath Dubey

Static site generation (SSG) is a technique used in web development that involves generating a static HTML file for a web page at build time, rather than generating it dynamically on the server or client-side when a user requests the page. SSG can provide several benefits, such as faster page load times, improved scalability, and reduced server load.

In Next.js, SSG is built-in and can be used alongside SSR or on its own. When a user requests a page that has been generated using SSG, the pre-rendered HTML file is served directly to the user, resulting in almost instant page load times. Additionally, since the HTML file does not need to be generated dynamically on the server or client-side, SSG can help reduce server load and improve scalability.

SSG can be particularly useful for websites that have content that changes infrequently or that can be pre-computed ahead of time. For example, a blog website that publishes new articles once a day can use SSG to generate static HTML files for each article at build time. This can greatly reduce the amount of work needed to generate each page when a user requests it, resulting in faster page load times and a more responsive website.

One important thing to note is that SSG may not be suitable for websites that have content that changes frequently or that relies heavily on dynamic data. In these cases, server-side rendering or client-side rendering may be more appropriate. However, Next.js provides support for all three rendering methods, allowing developers to choose the best option for their specific use case.
