Static Site Generation in Next.js
SSG stands for Static Site Generation, which is a technique used to generate static HTML pages at build time instead of generating them on the server on each request. Next.js is a framework for building React applications, and it provides built-in support for SSG.
ISR stands for Incremental Static Regeneration, which is a technique used in Next.js to generate static pages with dynamic content. ISR allows you to pre-render pages at build time and then re-generate them on-demand, as new data becomes available.
With ISR, you can create pages with dynamic content that are pre-rendered at build time, and then re-rendered in the background when the data changes, without requiring a full rebuild of the site.
This approach can improve the performance and scalability of your application, as well as reduce server costs.
