Simplifying Laravel Filtering with the Purity Package

Managing complex filters in Laravel applications can quickly clutter your controllers. The Purity package simplifies this — you keep your code clean and maintainable while adding powerful filtering and sorting capabilities.

1. Add filterable fields to your model

use Abbasudo\Purity\Traits\Filterable;

class Product extends Model
{
    use Filterable;

    protected $filterFields = [
        'name',
        'price',
        'category_id',
        'created_at',
    ];
}

2. Use URL-based filtering

Purity reads filters directly from the query string:

/products?filters[name][$contains]=laptop&filters[price][$gte]=500

3. Implement it in the controller

public function index()
{
    return Product::filter()->sort()->paginate(20);
}

That's it — one line in the controller, and your API supports rich filtering ($eq, $contains, $gte, $in, and more) plus sorting, without any custom query-building code.
