livewire 3 pagination breaks when going back to first page or 3rd or 4th page

Livewire 3 is a popular library for building dynamic, reactive web applications using Laravel. However, when implementing pagination in Livewire 3, some users have reported issues with the pagination breaking when navigating to the first, third, or fourth page. In this answer, we will discuss the possible causes of this issue and provide solutions.

One common cause of pagination breaking in Livewire 3 is due to the way Livewire handles state and event broadcasting. When navigating to a new page, Livewire sends a new request to the server to fetch the new data for that page. However, if the new page contains data that has already been loaded in a previous request, Livewire may not update the UI correctly, resulting in pagination issues.

To solve this issue, you can use Livewire's preserveState property on the pagination component. This property tells Livewire to keep the component's state between requests, ensuring that the UI remains consistent when navigating between pages. Here's an example of how to use it:

use Livewire\Component;

class PaginationExample extends Component
{
    public $page = 1;

    public function render()
    {
        $data = App\Models\User::paginate(10);

        return view('livewire.pagination-example', [
            'data' => $data,
        ]);
    }

    public function nextPage()
    {
        $this->page++;
    }

    public function prevPage()
    {
        $this->page--;
    }
}

<div x-data="{ currentPage: @entangle($dispatchFrom('page')) }">
    <button @click="prevPage()" :disabled="currentPage === 1">Previous</button>

    <table>
        <!-- Table content goes here -->
    </table>

    <button @click="nextPage()" :disabled="data.lastPage">Next</button>
</div>

const nextPage = () => {
    livewire.emit('page--increment');
};

const prevPage = () => {
    livewire.emit('page--decrement');
};

public function mount()
{
    $this->listenTo('page:increment', 'pageIncrement');
    $this->listenTo('page:decrement', 'pageDecrement');
}

public function pageIncrement()
{
    $this->page++;
}

public function pageDecrement()
{
    $this->page--;
}

Another cause of pagination breaking in Livewire 3 is due to caching. When using Laravel's built-in caching or other caching solutions, Livewire may serve stale data from the cache instead of fetching the latest data from the database. To prevent this, you can use Livewire's mount method to fetch the initial data and set a meta tag to prevent caching. Here's an example:

use Livewire\Component;

class PaginationExample extends Component
{
    public $page = 1;

    public function render()
    {
        $data = App\Models\User::paginate(10);

        return view('livewire.pagination-example', [
            'data' => $data,
        ])->header('Cache-Control', 'no-cache, no-store, must-revalidate');
    }

    // ...
}

In summary, to prevent pagination breaking in Livewire 3 when navigating to the first, third, or fourth page, you can use Livewire's preserveState property and ensure that Livewire fetches the latest data from the database by setting a meta tag to prevent caching in the response header.
