Client Side Rendering vs Server Side Rendering for Web Application Development

SSR vs CSR
Server-side rendering is a well-established traditional approach for displaying a web application’s content. It converts HTML files housed on the server into useful information, which is then sent back to the browser and displayed on the user’s screen in a matter of milliseconds.
With client-side rendering, after the initial source is loaded into the browser, website content is rendered entirely in the browser, eliminating the need for a different HTML page per route . With CSS, the browser only communicates with the server to obtain run-time data, and the user interface (UI) does not have to reload for each call to the server. While the initial page load speed is slower for the first page, it speeds up for subsequent pages.
Neither CSR or SSR is superior to the other, and both have their strengths and weaknesses The choice comes down to the project’s specific priorities and use cases. Progressive web applications (PWAs) can be developed with either approach, although
dynamic content that is continually refreshed (think Instagram) is better served by CSR. Static pages perform just as well with more traditional SSR, and may fare better on search engines, since SSR is more accessible to crawlers and bots.
Main Differences Between CSR vs SSR Web Apps
- Page Loading Speed: The time that elapses between a browser request and a server rendering is the page load time. While fast and slow are relative terms, a page that loads extremely slowly can negatively affect user experience. For SSR, page access is relatively fast across the board, while the loading speed of a site’s initial page is a bit slow with CSR, but speeds up with additional pages.
- Caching: A cache is a temporary storage location for files so they can be quickly accessed. Both browsers and servers use caching mechanisms for a user’s reusable scripts, speeding up both CSR and SSR. The key difference is that CSR web apps can run without an Internet connection once they are rendered in the browser, while SSR apps require a connection to send requests to the server.
SEO: Search engines use automated bots to crawl your website’s metadata to understand its content. That information is used to rank your page in the SE’s results listing. SSR pages are inherently optimized for search bots, since they already contain all their metadata. CSR pages, on the other hand, use plugins or
Which to Choose: SSR vs CSR
As frameworks become more sophisticated and efficient, and as web applications become more dynamic and interactive, developers are drifting more toward CSR for web applications. With CSR, developers only have to think about the client code, since the app’s functionality is not married to the server. But CSR is not necessary or preferable for every app. In cases where time-to-content and SEO are critical, SSR may be a better choice.
