Get type of prisma client before it is defined

import { PrismaClient } from "@prisma/client";

const extension = {
  model: {
    user: {
        example: () => "example",
      },
  },
};

const globalForPrisma = globalThis as unknown as { db: PrismaClient };
const db = globalForPrisma.db || new PrismaClient().$extends(extension);

export default db;

if (process.env.NODE_ENV !== "production") globalForPrisma.db = db;
