Step 1: Create Product Model and Migration

Begin by creating a Product model and migration to store product information in your database:

php artisan make:model Product -m

Schema::create('products', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->text('description');
    $table->decimal('price', 8, 2);
    $table->timestamps();
});

This step establishes the foundation for storing product details in your Laravel application.

Step 2: Implement Product Listing Component

Create a Livewire component to handle product listing with pagination. Define the necessary properties and methods within your Livewire component:

php artisan make:livewire ProductList

class ProductList extends Component
{
    public $perPage = 10;
    public $search = '';

    public function render()
    {
        $products = Product::where('name', 'like', '%'.$this->search.'%')->paginate($this->perPage);
        return view('livewire.product-list', ['products' => $products]);
    }
}

By utilizing Livewire, you can seamlessly fetch and display paginated product data.

Step 3: Create Product Listing Blade View

Generate the blade view to render the paginated product list:

<div>
    <input type="text" wire:model="search" placeholder="Search Products...">

    <ul>
        @foreach($products as $product)
            <li>{{ $product->name }} - ${{ $product->price }}</li>
        @endforeach
    </ul>

    {{ $products->links() }}
</div>

This view displays the paginated product data along with a search input for filtering products.

Step 4: Implement Search Functionality

Enhance your Livewire component with search functionality to filter products based on user input:

public function updatedSearch()
{
    $this->resetPage();
}

use Livewire\WithPagination;

class ProductList extends Component
{
    use WithPagination;

    public $perPage = 10;
    public $search = '';

    public function render()
    {
        $products = Product::where('name', 'like', '%'.$this->search.'%')->paginate($this->perPage);
        return view('livewire.product-list', ['products' => $products]);
    }
}

The search functionality allows users to dynamically filter products without reloading the page.

Step 5: Add Pagination Controls

Incorporate pagination controls to navigate through the paginated product list:

<div>
    {{ $products->links() }}
</div>

These pagination links enable seamless navigation between different pages of product listings.

Step 6: Customize Pagination Styling

Customize the pagination styling to match your application's design by leveraging Laravel Livewire's pagination customization:

<div>
    {{ $products->links('livewire.custom-pagination-links') }}
</div>

This approach allows you to tailor the pagination appearance to align with your application's aesthetics.

Step 7: Optimize Pagination Query

Optimize the pagination query by eager loading relationships and minimizing database queries:

$products = Product::with('category')->where('name', 'like', '%'.$this->search.'%')->paginate($this->perPage);

public function render()
{
    $products = Product::with('category')->where('name', 'like', '%'.$this->search.'%')->paginate($this->perPage);
    return view('livewire.product-list', ['products' => $products]);
}

Eager loading relationships enhances performance by fetching related data efficiently.

Step 8: Handle Empty Pagination Results

Address scenarios where the paginated product list returns no results by displaying a message to the user:

<div>
    @if($products->isEmpty())
        <p>No products found.</p>
    @else
        <ul>
            @foreach($products as $product)
                <li>{{ $product->name }} - ${{ $product->price }}</li>
            @endforeach
        </ul>
    
        {{ $products->links() }}
    @endif
</div>

Handling empty pagination results gracefully ensures a positive user experience.

Step 9: Add Pagination Meta Information

Include pagination meta information to provide users with contextual details about the current page and total items:

<div>
    <p>Displaying {{ $products->count() }} out of {{ $products->total() }} products.</p>
    {{ $products->links() }}
</div>

This meta information enhances user understanding of the paginated product list.

Step 10: Implement Pagination Refresh

Implement a pagination refresh mechanism to reload the paginated list upon specific actions or changes:

public function refreshProducts()
{
    $this->render();
}

Refreshing the pagination ensures that the displayed product list stays up to date with any modifications.

Step 11: Handle Pagination Edge Cases

Address edge cases such as navigating beyond the available pages or invalid page numbers by handling these scenarios gracefully:

public function updatedPage($value)
{
    if ($value <= 0 || $value > $this->products->lastPage()) {
        $this->resetPage();
    }
}

Properly managing pagination edge cases ensures a seamless user experience.
