Solution to prefetch in a component on nextjs - next.js

Question

I'm looking for a solution/module where I don't need to inject inital/fallback data for swr/react-query things from getServerSideProps. Like...
from
// fetcher.ts
export default fetcher = async (url: string) => {
return await fetch(url)
.then(res => res.json())
}
// getUserData.ts
export default function getUserData() {
return fetcher('/api')
}
// index.tsx
const Page = (props: {
// I know this typing doesn't work, only to deliver my intention
userData: Awaited<ReturnType<typeof getServerSideProps>>['props']
}) => {
const { data } = useSWR('/api', fetcher, {
fallbackData: props.userData,
})
// ...SSR with data...
}
export const getServerSideProps = async (ctx: ...) => {
const userData = await getUserData()
return {
props: {
userData,
},
}
}
to
// useUserData.ts
const fetcher = async (url: string) => {
return await fetch(url)
.then(res => res.json())
};
const url = '/api';
function useUserData() {
let fallbackData: Awaited<ReturnType<typeof fetcher>>;
if (typeof window === 'undefined') {
fallbackData = await fetcher(url);
}
const data = useSWR(
url,
fetcher,
{
fallbackData: fallbackData!,
}
);
return data;
}
// index.tsx
const Page = () => {
const data = useUserData()
// ...SSR with data...
}
My goal is making things related to userData modularized into a component.
