Understanding React Server Components

What this post added

This post introduces React Server Components (RSCs) as a paradigm shift in React development, moving data fetching and rendering to the server. It explains the historical context leading to RSCs, highlighting the limitations of traditional SSR and Suspense. RSCs are presented as a solution to improve performance and reduce client-side JavaScript bundle size by resolving dependencies and rendering on the server. The post details how RSCs interleave with Client Components and integrate with Suspense for faster rendering. It also discusses limitations, such as the inability to use lifecycle hooks in RSCs and the need for Client Components for interactivity and continuous updates. The integration with Next.js App Router is highlighted, where components are Server Components by default. The post also touches upon Server Actions as a mechanism for client-to-server mutability.
