Prisma: Asyncronous Extended Fields

Anyone familiar with any better way to accomplish the equivalent of

field resolvers

field resolvers

with prisma?

The Ask
I need an async field returned with each user

The Scenario
Say I want to

findMany

findMany

users

users

but I want a

likeCount

likeCount

and

followCount

followCount

fields returned with each result.

The

expand

expand

api looks to be on the right track but it looks like its unable to perform asynchronous computes for additional fields.

Such as if I wanted to add an async field called

likeCount

likeCount

user

user

which would be returned on each user result.

const xprisma = prisma
  .$extends({
    result: {
      user: {
        likeCount: {
          needs: { id: true },
          compute({id}) {
            return prisma.likes.count({where: userId: id})
          },
        },
      },
    },
  })

const xprisma = prisma
  .$extends({
    result: {
      user: {
        likeCount: {
          needs: { id: true },
          compute({id}) {
            return prisma.likes.count({where: userId: id})
          },
        },
      },
    },
  })

I know I can just _count
likes
likes
on
user
user
for this example. This is simplified for an example
