Using Prisma with Both SQLite and PostgreSQL

const prisma = (() => {
  switch (process.env.DATABASE_PROVIDER) {
    case 'postgresql':
      return new PrismaClientPostgresql({
        adapter: new PrismaPg({
          connectionString: process.env.DATABASE_URL,
        }),
      });

    case 'sqlite':
      return new PrismaClientSqlite({
        adapter: new PrismaBetterSQLite3({
          url: process.env.DATABASE_URL,
        }),
      });

    default:
      throw new Error(
        `Unsupported DATABASE_PROVIDER: ${process.env.DATABASE_PROVIDER}`
      );
  }
})();

// Works fine
await prisma.user.create({ data: { name: 'test', email: '' } });

// Type error:
/*
