Is implementing client components in Server Side pages an effective strategy for optimizing SSR performance?

In order to overcome the challenge of using client-side components in server-side pages, I made the decision to create a client-side wrapper to encapsulate these components within server-side pages. This way, I can manage all API calls and data fetching on the server and then pass it down to the components.

Do you think this is a good practice? Feel free to review the code snippet below:

ClientSideWrapper:

"use client";

interface ClientWrapperProps {
  children: React.ReactNode;
}
export const ClientWrapper = ({ children }: ClientWrapperProps) => {
  return <>{children}</>;
};

page.tsx

export default async function ResourcesPage({
  params,
}: {
  params: { slug: string };
}) {
  // Code for handling resources, tags, filtering, and structuring data
  ...

  // Rendering UI elements based on processed data
  ...
}

A classic case where the recommended approach involves nesting server components within client components can be found here. Importing server components directly inside client components is not supported, hence this pattern is suggested:

Best Practice: Passing Server Components to Client Components as Properties

In designing Client Components, it is advisable to utilize React props to define "slots" for Server Components.

The Server Component will be displayed on the server side, while the Client Component's rendering on the client side will include the output of the Server Component in the designated "slot".

An effective strategy often involves utilizing the React children prop for setting up the "slot". By modifying <ExampleClientComponent> to accept a generic children property and relocating the import and specific nesting of <ExampleClientComponent> to a higher level parent component.

Your code implementation closely mirrors this principle:

  • ResourcesPage is initially rendered on the server with the inclusion of ClientWrapper's children properties but excluding the actual ClientWrapper elements.

  • Subsequently, upon reaching the client side, the ClientWrapper elements are rendered, equipped with the children property that already contains the rendered outcome of the Server Component.
