<?php

namespace App\Services;

use Illuminate\Contracts\Pagination\LengthAwarePaginator;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Collection;
use LevelUp\Experience\Models\Experience;

class LeaderboardService
{
    private mixed $userModel;

    public function __construct()
    {
        $this->userModel = config(key: 'level-up.user.model');
    }

    public function generate(bool $paginate = false, ?int $limit = null): array|Collection|LengthAwarePaginator
    {
        return $this->userModel::query()
            ->with(relations: ['experience', 'level'])
            ->select('users.*')
            ->leftJoin('experiences', 'users.id', '=', 'experiences.user_id')
            ->orderByDesc('experiences.level_id')
            ->orderByDesc('experiences.experience_points')
            ->take($limit)
            ->when($paginate, fn (Builder $query) => $query->paginate(), fn (Builder $query) => $query->get())
            ->each(function ($user) {
                $user->level_id = optional($user->experience)->level_id ?? 1;
            });
    }
}

adding this into my personal project, so here's the code if you want an already done implementation ( Livewire 3 )

Livewire\Leaderboard.php

<?php

namespace App\Livewire;

use App\Models\User;
use Filament\Notifications\Notification;
use Illuminate\Support\Facades\Auth;
use LevelUp\Experience\Models\Achievement;
use Livewire\Component;
use App\Services\LeaderboardService as LLeaderboard;

class Leaderboard extends Component
{
    private $leaderboard;
    public $topThree;
    public $otherUsers;
    public $totalUsers;
    public $results;
    public $numResults = 10; // Number of users to load at once
    public $finished = false; // Flag to determine if all users have been loaded

    protected $listeners = ['leaderboardUpdated' => '$refresh'];

    public function mount()
    {
        $leaderboardService = new LLeaderboard();
        $this->leaderboard = $leaderboardService->generate();
        $this->totalUsers = $this->leaderboard->count();
        $this->topThree = $this->leaderboard->take(3);
        $this->otherUsers = $this->leaderboard->skip(3)->take($this->numResults);
    }

    public function render()
    {
        return view('livewire.leaderboard');
    }

    public function loadMore()
    {
        $this->results += $this->numResults;

        $leaderboardService = new LLeaderboard();
        $leaderboard = $leaderboardService->generate();
        $totalUsers = $leaderboard->count();

        $newUsers = $leaderboard->skip($this->results + 3)
            ->take($this->numResults);

        // Appending new users to otherUsers property
        $this->otherUsers = $this->otherUsers->concat($newUsers);

        if (($this->results + 3) >= $totalUsers) {
            $this->finished = true;
        }
    }

    public function updatedOtherUsers()
    {
        $this->dispatch('leaderboardUpdated');
    }
}

resources/views/livewire/leaderboard.blade.php ( alpineJS code is for infinite scrolling, remove that and loadMore function to remove it )

If a user doesn't have an entry under experiences, it defaults to Level 1

Thanks for the question! I am building gamified bookmarking. Has a few things that aren't from this package, but hey whatever helps, helps! ( achievements, quests, leveling, etc )
