NEXTJS: getServerSideProps not working into components - next.js

Question

Below is the code located at "Pages/home.js". // localhost:3000/home
import axios from 'axios';
import Section1 from '../components/home-sections/section-1';
const Homepage = ({ show }) => {
const Html = JSON.parse(show.response.DesktopHTML);
const renderSection = () => {
return Html.map((itemData,index)=>{
return(<div key={index}>{itemData.DisplayName}</div>)
})
}
return(
<div>
{ renderSection()}
<Section1 />
</div>
)
}
export const getServerSideProps = async ({ query }) => {
try {
const response = await axios.get(
`https://api.example.com/getHomeSection?title=Section 1`
);
return {
props: {
show: response.data,
},
};
} catch (error) {
return {
props: {
error: error.error,
},
};
}
};
export default Homepage;
Now same code I added into section-1.js and this file is located to "components/home-sections/section-1.js"
Now getServerSideProps is working fine in home.js, but in section-1.js it is not working.
Error: TypeError: show is undefined in section-1.js

Answer 1

You cannot use getServerSideProps in non-page components. You can either pass the prop from Home to HomeSection or create a context so the value can be available globally from the component tree
getServerSideProps can only be exported from a page. You can’t export
it from non-page files.

Answer 2

getServerSideProps can only be exported from Page components. It will not be run on components imported into a page.
However, you could export a function from the component that returns the props, and call that function from the page's getServerSideProps function.
Create a getServerSideProps function on the component.
// #components/MyComponent.tsx
import { GetServerSidePropsContext } from 'next';
function MyComponent(props: IMyComponentProps) {
return (<div>MyComponent</div>;)
}
MyComponent.getServerSideProps = async (context: GetServerSidePropsContext): Promise<{ props: IMyComponentProps }> => {
return { props: { ... } };
}
export default MyComponent;
In your page's getServerSideProps function, call the component's getServerSideProps function and merge the props from the component with the props from the page.
// mypage.tsx
import MyComponent from '#components/MyComponent';
const Page: NextPageWithLayout = (props: IIndexPageProps) => {
return <MyComponent />;
}
export async function getServerSideProps(context: GetServerSidePropsContext): Promise<{ props: IIndexPageProps }> {
let componentServerSideProps = await MyComponent.getServerSideProps(context);
let otherServerSideProps = { props: { ... } };
return {
props: {
...componentServerSideProps.props,
...otherServerSideProps.props
}
};
}
