NextJS 12.1 SSR & SSG: Everything you need to know

NextJS is a popular framework for building React applications. With the release of NextJS 12.1, there are some exciting updates to the server-side rendering (SSR) and static site generation (SSG) capabilities. Let’s take a look at everything you need to know about these features.

Server-side rendering (SSR)

Server-side rendering is a technique used to render React components on the server rather than in the browser. This can improve performance and SEO by delivering fully rendered HTML to the client. NextJS 12.1 includes updates to its SSR capabilities, making it easier to implement and more efficient to use.

New API for SSR

NextJS 12.1 introduces a new API for implementing server-side rendering. This API provides a more streamlined and intuitive way to define which pages should be rendered on the server, and allows for greater control over the rendering process.

Improved performance

The latest version of NextJS includes optimizations for server-side rendering, resulting in improved performance and faster page load times. This makes SSR an even more attractive option for delivering high-performance web applications.

Static site generation (SSG)

Static site generation is a technique used to pre-render pages at build time, rather than on the fly. This can result in significant performance improvements and is especially useful for content-heavy websites. NextJS 12.1 includes updates to its SSG capabilities, making it even easier to use and more powerful than before.

Incremental static regeneration (ISR)

One of the most exciting new features in NextJS 12.1 is incremental static regeneration (ISR). This allows for pages to be re-generated at runtime, rather than at build time, providing a more dynamic and responsive user experience. ISR is a game-changer for SSG and opens up new possibilities for building highly interactive websites with NextJS.

Improved build performance

NextJS 12.1 includes optimizations for the build process, resulting in faster build times and improved performance for static site generation. This makes it easier and more efficient to generate static sites with NextJS, even for large and complex websites.

Conclusion

NextJS 12.1 introduces some exciting updates to its server-side rendering and static site generation capabilities. With improvements to both SSR and SSG, as well as new features like incremental static regeneration, NextJS continues to be a powerful and versatile framework for building high-performance web applications. Whether you’re building a content-heavy website or a highly interactive web app, NextJS 12.1 has everything you need to deliver a great user experience.
