revalidateTag for non fetch functions like prisma

[alsherif-khalaf]

How can I tag this function for example :

  const todos = await prisma.todo.findMany();

like this :

fetch(url, { next: { tags: [...] } });

to use it via revalidateTag('tag') ?

Hi alsherif-khalaf

The only way I could get it to work was by using route handlers, and then I added the prisma logic in there.

Here is an example where I'm using fetch to an API route:

async function getProfileByUserId(id: string ) {
  const url = `${basePath}/api/read/profile/getProfileByUserId?id=${id}`

  const res = await fetch(url, { next: { tags: ["user"] } })

  return res.json()
}

If you found a better way, please let me know.

Check out unstable_cache. https://nextjs.org/docs/app/api-reference/functions/unstable_cache
I think this is a perfect use case for it, caching non-fetch data requests.

Can i revalidate the cache using revalidateTag when I use this unstable_cache function?
