Snippet to add Laravel paginator

[NWBY]

Using the Laravel paginator with Inertia is great. However, it is not mentioned in the documentation anywhere. I found the solution in the PingCRM demo app, but it would be nice to have this in the docs for new user to be able to set up the paginator straight away when starting a new project.

I've dropped the code from PingCRM demo so that it is clear what I am talking about.

protected function registerLengthAwarePaginator()
    {
        $this->app->bind(LengthAwarePaginator::class, function ($app, $values) {
            return new class(...array_values($values)) extends LengthAwarePaginator {
                public function only(...$attributes)
                {
                    return $this->transform(function ($item) use ($attributes) {
                        return $item->only($attributes);
                    });
                }

                public function transform($callback)
                {
                    $this->items->transform($callback);

                    return $this;
                }

                public function toArray()
                {
                    return [
                        'data' => $this->items->toArray(),
                        'links' => $this->links(),
                    ];
                }

                public function links($view = null, $data = [])
                {
                    $this->appends(Request::all());

                    $window = UrlWindow::make($this);

                    $elements = array_filter([
                        $window['first'],
                        is_array($window['slider']) ? '...' : null,
                        $window['slider'],
                        is_array($window['last']) ? '...' : null,
                        $window['last'],
                    ]);

                    return Collection::make($elements)->flatMap(function ($item) {
                        if (is_array($item)) {
                            return Collection::make($item)->map(function ($url, $page) {
                                return [
                                    'url' => $url,
                                    'label' => $page,
                                    'active' => $this->currentPage() === $page,
                                ];
                            });
                        } else {
                            return [
                                [
                                    'url' => null,
                                    'label' => '...',
                                    'active' => false,
                                ],
                            ];
                        }
                    })->prepend([
                        'url' => $this->previousPageUrl(),
                        'label' => 'Previous',
                        'active' => false,
                    ])->push([
                        'url' => $this->nextPageUrl(),
                        'label' => 'Next',
                        'active' => false,
                    ]);
                }
            };
        });
    }
