#passing server side data to client side
sand beaconBOT
The error you're encountering, "Maximum call stack size exceeded", is typically thrown when there's a recursive call with no exit condition, causing the stack overflow. However, in the context of Next.js and Server Components, this error might be related to the serialization of data passed from server to client components.
In Next.js, when passing data from a Server Component to a Client Component, the data needs to be serializable by React. If your Client Components depend on data that is not serializable, you might encounter issues. If your data is not serializable, you can fetch data on the client with a third party library or on the server via a Route Handler (source (https://nextjs.org/docs/app/building-your-application/rendering/composition-patterns)).
When passing data between a Server and Client Component through props, the data is serialized (converted to a string) for use in the browser. It does not need a special type. It’s typed the same as passing any other props between components (source (https://nextjs.org/docs/app/building-your-application/configuring/typescript)).
In your case, you might want to check if the product object you're passing to the DisplayCard component is serializable. If it's not, you might need to adjust your data fetching or passing strategy.
Here's an example of how you can fetch data in your server-component and pass it as props to your client component:
// app/page.jsx
import { use } from 'react';
import { ProductCard } from './product-card';
const Index = () => {
const product = use(
fetch('<https://dummyjson.com/products/1'>).then((res) => res.json())
);
return <ProductCard title={product.title} />;
};
export default Index;
// app/product-card.jsx
'use client';export function ProductCard({title}) {
return <div>{title}</div>;
}
(**source** (<https://github.com/vercel/next.js/issues/46084>))
Please note that the `use` hook is not stable yet to use in client components to fetch data. That's why the Next.js team recommends using it in server components or using async server components directly to fetch data (**source** (<https://github.com/vercel/next.js/issues/46084>)).
If you're still encountering issues, you might want to provide more details about your `Product` schema and the structure of the data you're trying to pass to the client component.

I don't think I can use fetch for my backend data, since there all coming from my async functions which connected to mongoose @sand beacon

Let me check the knowledge base for you. One moment! :books:
If you're fetching data from a MongoDB database using Mongoose in a Next.js application, you can still use server-side rendering (SSR) or server-side generation (SSG) to fetch your data and pass it to your components. However, passing data directly from server components to client components requires the data to be serializable.
In your case, you're fetching data in a server-side function and trying to pass it to a client component. If the data you're passing is not serializable, you might encounter issues.
Here's an example of how you can fetch data on the server and pass it to your components:
// pages/index.js
import { getAll } from '../path-to-your-function';
export async function getServerSideProps() {
const allProducts = await getAll();
// Pass data to the page via props
return { props: { allProducts } };
}
export default function HomePage({ allProducts }) {
return (
<div>
{allProducts.map((product) => (
<DisplayCard key={product._id} product={product} />
))}
</div>
);
}
In this example, getServerSideProps is a Next.js function that runs on the server-side before rendering the HomePage component. It fetches the data using your getAll function, and then passes the data to the HomePage component via props.
The DisplayCard component then receives the product data as a prop and can use it to render the product information.
Remember, if you're using Next.js 12 or newer, you should use the use hook for data fetching in server components. However, the use hook is not stable yet to use in client components to fetch data. That's why the Next.js team recommends using it in server components or using async server components directly to fetch data (source (https://github.com/vercel/next.js/issues/46084)).

Sorry @graceful forge, I seem to be having a bit of trouble. Don't worry though, I've pinged my supprt and they will try to fix me up! :technologist:
Perhaps try again in 15mins?

Let me check the knowledge base for you. One moment! :books:
The error message you're seeing indicates that getServerSideProps is not supported in the file you're trying to use it in. According to the Next.js documentation, getServerSideProps can only be used in a page. Pages in Next.js are files inside the pages directory of your project.
In your case, it seems like you're trying to use getServerSideProps inside a file that's not in the pages directory (app/page.tsx).
To resolve this issue, you should move your page.tsx file to the pages directory and use getServerSideProps there. Here's an example of how you can structure your project:
- pages
- index.tsx
- lib
- actions.ts
- components
- DisplayCard.tsx
And here's how you can use getServerSideProps in your index.tsx file:
// pages/index.tsx
import { getAll } from '../lib/actions';
import DisplayCard from '../components/DisplayCard';
export async function getServerSideProps() {
const allProducts = await getAll();
// Pass data to the page via props
return { props: { allProducts } };
}
export default function HomePage({ allProducts }) {
return (
<div>
{allProducts.map((product) => (
<DisplayCard key={product._id} product={product} />
))}
</div>
);
}
In this example, getServerSideProps fetches the data on the server-side before rendering the HomePage component. It uses your getAll function to fetch the data, and then passes the data to the HomePage component via props. The DisplayCard component then receives the product data as a prop and can use it to render the product information.
