This post will examine various web application rendering types well examine server-side rendering (SSR) in react in detail and contrast its benefits with client-side rendering which is more common undoubtedly a large portion of you launch your apps using react cli also known as creating react app CRA although this tactic has numerous advantages using CRA when developing has some disadvantages as well when you view the pages source code, for instance, you will notice that a webpage from a web app launched using CRA includes a section that is primarily empty and only the part
This is due to the fact that CRA renders your application on the client side, necessitating the user’s browser to download the built.js file prior to the rest of the page loading. The site’s initial load time increases as a result of some web crawlers being unable to index the site.
Does this improve the effectiveness of your app? Yes, this is the situation where React’s server-side rendering is useful.
What is server-side rendering (SSR)?
Client-side libraries have replaced the classic SSR programs that dominated the early web. Server-side rendered React apps use the Node server platform nowadays, in contrast to earlier server-rendered apps.
Compared to client-side rendered apps, SSR apps have a number of disadvantages, but they also offer faster initial load times and better SEO performance. The server first creates a new page for the browser with each request. As a result, each time a request is sent to the server, the browser will need to reload all of its scripts, styles, and templates.
What are single-page applications?
What are static-generated applications?
Creating static-generated websites requires the use of a static site generator, such as Gatsby. There is no requirement for Node or any other server-side capability in order to publish these static files to a static hosting server. As a result, when the app is first opened in the browser, it operates similarly to a standard SPA. The information is always seen in its entirety right away.
Static-generated programs do not support real-time rendering. Real-time web applications like chat or forum software should not be created using this rendering method.
Why move to React server-side rendering (SSR)?
As I mentioned before, server-side rendering describes the process of rendering and loading a page from the server. However, after the release of server-side (universal) React, things have changed somewhat.
A server-driven initial page loads, whereas client-driven subsequent pages load directly. You get the best of both worlds thanks to the potency of the first server-side material and the speedy subsequent loads, which only request the content necessary for subsequent requests.
What is the Disadvantage of rendering on the server side?
Disadvantages of server-side rendering could include:
Although it is effective to render static HTML on the server, doing so for larger, more complicated apps can cause load times to rise.
Although rendering on the server is appropriate for static site generation, more complicated apps may have slower page rendering overall due to frequent server calls and entire page reloads.
Server Side Rendering (SSR) vs Client Side Rendering (CSR)
Along with the above-mentioned advantages, transferring to SSR also comes with the following advantages:
Although it is possible to start without frameworks, I wouldn’t recommend it because a React SSR project has many moving parts and many aspects to consider. You are in charge of performing operations like bundling, minification, hot reloading, and others on your own, for instance.
React SSR frameworks
I suggest investing in a framework if you want to render React on the server side. Think about these frameworks:
Additional alternatives:- Nuxt.js, Angular Universal, SvelteKit, and Gatsby.
The application delivered by SSR offers a number of advantages and is SEO-friendly.
The advantages, which we addressed in this piece, include:
- High Performance
- Search engine visibility
- User experience
- Social sharing
