Passing data from the server to the client in your Next.js Pages

Being a server-side rendered app, we can pass data from the server to the client whenever the user visits the page. Here is how

Passing data from the server to a client during SSR is a common task.

In Makerkit, you can use the following pattern to pass data from the server to the client.

We use withAppProps to initialize the data on the server and making the required checks.
We augment the props property returned by withAppProps with the data we want to pass to the client.

import { GetServerSidePropsContext } from "next";
import { withAppProps } from '~/lib/props/with-app-props';
type Data = {
  // ...
}
function Page({ data }: { data: Data }) {
  // you can use the data here
}
export async function getServerSideProps(
  ctx: GetServerSidePropsContext
) {
  const { props } = await withAppProps(ctx);
  // We augment the props with the data we want
  // to pass to the client
  // replace the below with your own logic
  const data = await getDataFromServer();
  return {
    props: {
      ...props,
      data,
    }
  };
}

As you can see - we augment the props property returned by withAppProps with the data we want to pass to the client.

The property data will then be available in the props property of the page component Page.

type Data = {
  // ...
}
interface PageParams {
  data: Data
}
function Page({ data }: { data: Data }) {
  // you can use the data here
}
export default Page;
