React Server Components

Rendering components on the server for improved performance is a key benefit.

React Server Components (RSC) represent a new paradigm in React, enabling component rendering on the server to reduce JavaScript bundle sizes and boost application performance. Server Components allow direct data fetching without API endpoints and can leverage server resources directly.

Rendering on the Server

They are stateless and do not have side effects.

RSCs can utilize `async/await` for asynchronous operations, enhancing performance and simplifying code.

Included in JavaScript Bundle

Utilized within Next.js.

Server Components (by default) are included within the main JavaScript bundle, optimizing loading times.

Frequently asked questions

What is React Server Components?

React Server Components are a new feature in React that allows you to render components on the server, improving performance and reducing bundle sizes by fetching data directly from the server.

Currently, where can I use React Server Components?

As of now, React Server Components are primarily implemented in Next.js 13+ with the App Router. The React team is developing a reference implementation, but Next.js remains the best choice for production usage. Other frameworks like Remix and Gatsby are also planning to add support.

Can Server Components handle user interactions?

Server Components cannot directly handle user interactions. You should use Server Actions or API routes to manage these actions, with Server Actions allowing you to trigger server functions from Client Components and Next.js providing built-in support.

Can Server Components utilize React Context?

No, Server Components cannot use React Context because they are stateless and do not re-render. Context is primarily intended for Client Components; to pass data to a Server Component, use props.
