前提

下記ライブラリを利用
https://github.com/nuwave/lighthouse

ページネーションのカスタム

query {
  TQuery(first:10, page:1) {
    data{
      title
      genre
      writer
    }
    paginatorInfo{
      total
    }
  }
}

src/graphql/schema.graphql

type Query {
    TQuery: [Test!]! @paginate(builder: "App\\GraphQL\\Queries\\TestQuery")
}

type Test {
    title: String
    writer: String
    genre: Int
}

namespace App\GraphQL\Queries;

use Illuminate\Support\Facades\DB;

class TestQuery
{
    public function __invoke($_, array $args)
    {
        return DB::table('test1')
            ->join('test2',[['test1.id', '=', 'test2.test1_id']])
            ->orderBy('test2.created_at', 'asc');
    }
}
