What are some ways to create a dynamic child server component?

Take a look at the following code snippet

// layout.tsx

export default function Layout({children}: any) {
  return <div>
      {children}
  </div>
}
// page.tsx

export const dynamic = "force-dynamic";

const DynamicChild = dynamic(() => import("@/DynamicChild"), {
    ssr: true,
})

export default function Page({children}: any) {
  return <div>
      <DynamicChild />  
  </div>
}
// DynamicChild.tsx



export default function DynamicChild() {
  return <div>
      {process.env.imporantEnvVar ? "cat": "dog"}  
  </div>
}

When a page is set as

export const dynamic = "force-dynamic";
, the dynamic rendering of DynamicChild occurs. However, not all pages are suitable for adding "force-dynamic", and they should be primarily rendered statically during build time except for the <DynamicChild> component.

How can you achieve this objective while still ensuring that all components remain server-side rendered?

Answer №1

To dynamically render a page in Next.js, you don't need to explicitly export dynamic = "force-dynamic". The framework automatically detects dynamic data usage such as cookies, headers, search params, fetch with revalidate: 0 or cache: "no-store", and more.

If you want to force dynamic rendering without using those APIs, you can invoke unstable_noStore within any component:

// dynamic-component.tsx

import { unstable_noStore as noStore } from 'next/cache';

export default function DynamicChild() {
 
  noStore();

  return <div>
      {process.env.imporantEnvVar ? "cat": "dog"}  
  </div>
}

By calling noStore, Next.js will tag the page (or component when using PPR) for dynamic rendering.


It's recommended to statically render pages at build time whenever possible.

If you aim to statically render most of the page except for dynamic components, consider enabling Partial Pre-render (PPR).


Additional Note:

  1. dynamic() is unrelated to Server Components.
const DynamicChild = dynamic(() => import("@/DynamicChild"), {
    ssr: true,
})

The usage of dynamic() only impacts Client Components, not Server Components. It comes into play when importing a Client Component within another Client Component.

  1. Environment Variables are embedded in output chunks during build time and changing them requires rebuilding. This clarification ensures that modifying process.env.imporantEnvVar won't alter the output instantly.
