Confused about which server-side rendering (SSR) framework to use for your React project? 

Well, the two popular frameworks that stand out here for SSR are NextJS and Remix.

And this article provides you with a brief insight into the benefits of SSR and a detailed comparison between the two popular frameworks for web application development- NextJS vs Remix.

In modern web application development, server-side rendering plays a pivotal role in optimizing performance, improving SEO, enriching user experience, and ensuring compatibility across various platforms. And that's why, selecting the appropriate framework for app development can ultimately determine the triumph or setback of your project.

So, let’s look into the detailed comparison between NextJS vs Remix and the basics of SSR.

What is server-side rendering in a web app?

Server-side rendering (SSR) is a technique in web development where web pages are generated on the server and sent to the client's browser as fully rendered HTML documents.

The technique has become increasingly popular due to its benefits mentioned below:

Faster initial page loading

SSR enables sending a fully rendered HTML page to the client and reduces the time required for the browser to download and process JavaScript files before rendering the content, improving the overall browser experience. 

Improved SEO

For search engines, it's easy to crawl and index the content of SSR-rendered pages since the complete HTML content is available upfront. This improves the visibility of web pages in search engine rankings and helps drive organic traffic to your website.

Enhanced user experience

With SSR, users receive a pre-rendered page from the server, enabling them to see content faster and navigate the website smoothly. This reduces the perceived loading time and provides a more seamless and engaging user experience.

Cross-platform capabilities

SSR ensures consistent rendering across various devices and platforms, including different browsers, operating systems, and screen sizes. By generating HTML on the server, SSR minimizes the discrepancies that can occur with client-side rendering and ensures a uniform experience for all users.

To take advantage of these benefits you can use frameworks like NextJS and Remix
