Extending the default PrismaAdapter you get

I want to extend the default prisma adapter to be able to award a badge to the first 100 users to sign up for my site. Unfortunately, the following code actually breaks nextjs entirely and becomes a zombie process. Not quite sure what I'm doing wrong here:

const extendedAdapter: typeof PrismaAdapter = (db) => {
  const adapter = PrismaAdapter(db);
  assert(adapter.createUser !== undefined);
  return {
    ...adapter,
    createUser: async (user) => {
      const created = await adapter.createUser!(user);

      const userCount = await db.user.count();
      console.log('BADGE', db.userBadge);

      if (userCount <= 100) {
        await db.userBadge.create({
          data: {
            award: Award.FIRST_100_USER,
            userId: created.id,
          }
        });
      }

      if (userCount <= 1000 && userCount > 100) {
        await db.userBadge.create({
          data: {
            award: Award.FIRST_1000_USER,
            userId: created.id,
          }
        });
      }

      return created;
    }
  }
}

const extendedAdapter: typeof PrismaAdapter = (db) => {
  const adapter = PrismaAdapter(db);
  assert(adapter.createUser !== undefined);
  return {
    ...adapter,
    createUser: async (user) => {
      const created = await adapter.createUser!(user);

      const userCount = await db.user.count();
      console.log('BADGE', db.userBadge);

      if (userCount <= 100) {
        await db.userBadge.create({
          data: {
            award: Award.FIRST_100_USER,
            userId: created.id,
          }
        });
      }

      if (userCount <= 1000 && userCount > 100) {
        await db.userBadge.create({
          data: {
            award: Award.FIRST_1000_USER,
            userId: created.id,
          }
        });
      }

      return created;
    }
  }
}

Then later on

`
export const authOptions: NextAuthOptions = {
  {...}
  adapter: extendedAdapter(db),
  {...}
}

Solution:

Was able to make it work like this: ``` import { PrismaAdapter } from "@next-auth/prisma-adapter" import { Award, type PrismaClient } from "@prisma/client"...

I'm suspecting that the adapter's createUser is opening a transaction that I'm not tapping into, creating a softlock?

Was able to make it work like this:

import { PrismaAdapter } from "@next-auth/prisma-adapter"
import { Award, type PrismaClient } from "@prisma/client"
import { type AdapterUser } from "next-auth/adapters"

const CustomAdapter = (client: PrismaClient) => {
  const adapter = PrismaAdapter(client);
  return {
    ...adapter,
    async createUser(user: Omit<AdapterUser, 'id'>) {
      const created = await client.user.create({
        data: user,
      })

      const count = await client.user.count();

      if (count <= 100) {
        await client.userBadge.create({
          data: {
            award: Award.FIRST_100_USER,
            userId: created.id,
          }
        });
      }

      if (count <= 1000 && count > 100) {
        await client.userBadge.create({
          data: {
            award: Award.FIRST_1000_USER,
            userId: created.id,
          }
        });
      }

      return created as AdapterUser;
    },
    
  }
}

export default CustomAdapter;

import { PrismaAdapter } from "@next-auth/prisma-adapter"
import { Award, type PrismaClient } from "@prisma/client"
import { type AdapterUser } from "next-auth/adapters"

const CustomAdapter = (client: PrismaClient) => {
  const adapter = PrismaAdapter(client);
  return {
    ...adapter,
    async createUser(user: Omit<AdapterUser, 'id'>) {
      const created = await client.user.create({
        data: user,
      })

      const count = await client.user.count();

      if (count <= 100) {
        await client.userBadge.create({
          data: {
            award: Award.FIRST_100_USER,
            userId: created.id,
          }
        });
      }

      if (count <= 1000 && count > 100) {
        await client.userBadge.create({
          data: {
            award: Award.FIRST_1000_USER,
            userId: created.id,
          }
        });
      }

      return created as AdapterUser;
    },
    
  }
}

export default CustomAdapter;
