Now Make 2 routes in your Route file

Route::get('posui-item-search', [
    'as' => 'posui.item.search',
    'uses' => 'MyController@search'
]);

Route::get('posui-get-single-item', [
    'as' => 'posui.get.single.item',
    'uses' => 'MyController@singleItem'
]);

Add this in your Controller

use Takielias\Posui\Posui;

You can Get the view

    function posuiview()
    {
        $template = Posui::getPosUiView();
        return view('welcome', compact('template'));
    }

Search Item

    function search(Request $request)
    {
        $rt = [
            'item_id' => 'id',
            'item_code' => 'product_code',
            'item_name' => 'product_name',
            'item_price' => 'product_price',
            'item_image' => 'product_image',
            'item_description' => 'product_description',
            'item_quantity' => 'product_quantity',
        ];
        $data = Posui::searchItem(ItemModel::query(), $rt, $request);
        return response()->json($data);
    }

Here product_code, product_name, product_price etc are representing your Item table column name

Select Single Item

    function singleItem(Request $request)
    {
        return Posui::getSingleItem(ItemModel::query(), $request);
    }
