When it comes to developing resilient, scalable, and easily manageable web applications, ReactJS emerges as an all-encompassing solution. In recent years, the dynamics of front-end development have undergone transformative shifts to the advancements in ReactJS. React Server Components have recently made their debut, evoking considerable excitement and buzz. These latest advancements have spurred unparalleled enthusiasm in the tech community.
In this blog, we delve into the world of React Server Components. Discover the necessities and benefits associated with this powerful technology, and explore how it unlocks performance excellence in system integration. But first, let’s lay the foundation with the basics.

What are React Server Components?

If there was a one-line answer to what React Server Components (RSCs) are, you could say that they blur the line between a client-side rendered application and a server-side rendered application. With React Server Components, components can load the data on the server and ship only what is asked for. Moreover, RSCs reduce the client bundle size, making a huge impact on the size of the application, and giving a boost to the overall performance.

The Evolution: CSR, SSR, and RSC

Client Side Rendering (CSR)

  • With CSR the client receives a bare-bones HTML page that contains a JavaScript bundle.
  • React renders the components and adds all the required content in the browser with the help of JavaScript.
  • Page loads after the first load are subsequently faster.
  • As the pages don’t contain pre-rendered HTML, it becomes hard for the crawlers to crawl the page which impacts the SEO drastically.

Client Side Rendering

Server Side Rendering (SSR)

  • With Server-side rendering, the components do get rendered on the server, sending to the client the HTML necessary for the initial page load.
  • After the initial page load, the client takes charge of that component, making it a client-side component.
  • So what SSR does is improve the initial page load time and make the application look like a traditional server-side rendered app.

Server Side Rendering

React Server Components (RSC)

  • React Server Components are also rendered on the server, but not just for the initial page load – for every subsequent request, the component gets rendered on the server.
  • Each cycle of rendering on the server only sends a stream to the client, not delivering any javascript bundles, improving the performance of the application.

The Challenges with System Integration:

When implementing a client-side rendering architecture, various challenges may arise, especially when attempting to integrate multiple systems. Connecting different systems can pose numerous challenges and hurdles. The interplay of numerous components, the variety of software platforms, and the intricacies of synchronization and coordination all add levels of complexity that must be constantly monitored and handled. Let’s delve deeper into these topics to better understand the various concerns and considerations when integrating systems within a client-side rendering framework.

Having Multiple Data Sources: In scenarios with a lot of requests directed at various services—whether databases or APIs—the applications will be faced with increased latency issues.

Data Inconsistencies: If the client presents data in an inconsistent state, it can negatively impact the user experience. This situation may arise when data is fetched from various systems.

Scalability: As more and more systems are integrated, metrics like time-to-load, time-to-interact, and latency can significantly increase the client-side workload.

Using React Server Components as a Fix

Let’s delve into how React server components can efficiently tackle these challenges and enhance the overall application speed.

A single tied-up source for data requests: By adding Server Components, all requests are efficiently managed on the server. This seamless integration of data from diverse sources, such as databases and services, allows for streamlined delivery of a single response to the client side. Consequently, the need for a client-side application to compile data from multiple endpoints is significantly reduced.

Consistency of Data: Establishing a singular, comprehensive source from which all data retrieval and processing takes place guarantees data consistency and eliminates redundancy. This approach ensures absolute accuracy and efficiency in managing information.

Integrating with Scalability in Mind: With a thin client-side layer, React Server Components ensure that only the necessary HTML stream is delivered from the server. This approach guarantees a responsive and lightweight application, regardless of the complexities in the backend.

Harnessing the advantages of RSCs enables system integration to reap the benefits of enhanced performance, simplified data fetching, and a seamless development experience. RSCs seamlessly integrate with existing React applications, making them a valuable asset for elevating system integration projects. As RSCs evolve, they possess the potential to revolutionize system integration practices and deliver outstanding performance across a diverse range of applications.

At iQuasar, our expertise in seamlessly integrating RSCs into React applications places us at the forefront of system integration. As RSCs continue to evolve, they are set to redefine integration dynamics, enhancing performance across various applications.
