SEO Friendly URLs

I want to build SEO friendly URLs for ecommerce website and until now I was using https://github.com/spatie/laravel-sluggable but I want to take it even further.

I want to have this structure:

• site.com/category1 -> CategoryController::show()
• site.com/category1/subcategory1 -> CategoryController::show()
• site.com/category1/product1 -> ProductController::show()
• site.com/category1/subcategory1/product2 -> ProductController::show()

One way it will be to have something like:

/**
 * First we check if it is category
 */
Route::get('{categories}', function ($categories) {
    $categories = explode('/', $categories);
    $current_category_slug = array_pop($categories);
    if($current_category = Category::where("slug",$current_category_slug)->first()) {
        return 'category view';
    }
})->where('categories', '^[a-zA-Z0-9-_\/]+$');
/**
 * Else if it is a product
 */
Route::get('{categories}', function ($categories) {
    $categories = explode('/', $categories);
    $current_product_slug = array_pop($categories);
    if($current_category = Pruduct::where("slug",$current_product_slug)->first()) {
        return 'product view';
    }
})->where('categories', '^[a-zA-Z0-9-_\/]+$');

Better way

I think a better way will be to store all the possible urls in the database and cache them with redis. Also in the database I will store the controller and action I found one old package - https://github.com/dmcdenissen/urlalias

Does anyone have better suggestion or maintained package?
