Updating cart using AlpineJS only

[rrrrando]

Hey!

I am trying to update item quantity in the cart view using AJAX via AlpineJS, but some of the needed data like total_including_tax and variant images are not in the api response. I think i should create a custom endpoint for that, but I'm stuck on what would be the best way to get all the cart data. If someone could point me to the right direction, it would be much appreciated.

While Simple Commerce does have a dedicated endpoint to return the cart & its line items (GET !/simple-commerce/cart), it won't include the total_including_tax bit you're after (since it's a tag, not actually part of the augmentation).

If you need that (or any other bits of information not returned by that endpoint), you'd have to make your own controller & route:

// app/Http/Controllers/CartController.php
<?php

namespace App\Http\Controllers;

use DuncanMcClean\SimpleCommerce\Orders\Cart\Drivers\CartDriver;
use Illuminate\Http\Request;

class CartController extends Controller
{
    use CartDriver;

    public function __invoke(Request $request)
    {
        $order = $this->getCart();

        if (! $order) {
            abort(404);
        }

        return response()->json([
            'order_number' => $order->orderNumber(),
            'items' => $order->lineItems()
                ->map(function ($lineItem) {
                    return array_merge($lineItem->toArray(), [
                        'total_including_tax' => $lineItem->totalIncludingTax(),
                    ]);
                })
                ->all(),
            // ... anything else you want to return
            // see the docs for reference: https://simple-commerce.duncanmcclean.com/php-api#content-orders
        ]);
    }
}

// routes/web.php

use App\Http\Controllers\CartController;

Route::get('/cart-json', CartController::class);
