It's small tool to convert info: GraphQLResolveInfo to select object accepted by prisma client this will give you the best performance because you will just query exactly what you want

// nexus
t.field('findOneUser', {
  type: 'User',
  nullable: true,
  args: {
    where: arg({
      type: 'UserWhereUniqueInput',
      nullable: false,
    }),
  },
  resolve(_parent, { where }, { prisma }, info) {
    return prisma.user.findOne({
      where,
      ...getPrismaSelect(info),
    });
  },
});
// normal resolver
const resolvers = {
  Query: {
    user(_parent, { where }, { prisma }, info) {
      return prisma.user.findOne({
        where,
        ...getPrismaSelect(info),
      });
    },
  },
};

Example query

query {
  findOneUser(where: { id: 1 }) {
    id
    email
    name
    posts(
      where: { title: { contains: "a" } }
      orderBy: { createdAt: asc }
      first: 10
      skip: 5
    ) {
      id
      title
      comments(where: { contain: { contains: "a" } }) {
        id
        contain
      }
    }
  }
}

convert to

{
  select: {
    id: true,
    email: true,
    name: true,
    posts: {
      select: {
        id: true,
        title: true,
        comments: {
          select: { id: true, contain: true },
          where: { contain: { contains: 'a' } }
        }
      },
      where: { title: { contains: 'a' } },
      orderBy: { createdAt: 'asc' },
      first: 10,
      skip: 5
    }
  }
