Learn the fundamentals of React Server Components, to better understand why (and when) to adopt. React Server Components (RSCs) augment the fundamentals of React beyond being a pure rendering library into incorporating data-fetching and remote client-server communication within the framework. Below, we’ll walk you through why RSCs needed to be created, what they do best, and when to use them. We'll also touch on how Next.js eases and enhances the RSC implementation details through the App Router. Link to heading Why do we need Server Components? Take a look at the world before React. With languages like PHP, we had a tighter relationship between client and server. In a monolithic architecture, you could reach out to the server to call data right within the page you were making. However, there were also disadvantages—namely, difficulty scaling monolithic applications due to cross-team dependencies and high traffic demands. React was created for composability and incremental adoption into existing codebases.…
