This is my first time playing around with Magento. I'm building a module and I want to listen when a product is added to the cart so, I've tried to use the controller_action_postdispatch_checkout_cart_add event but it doesn't seem to be firing.

In the events.xml file I have:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
   <event name="catalog_controller_product_view">
        <observer name="test_mymodule_catalog_controller_product_view" instance="Test\MyModule\Observer\CatalogProductView" />
    <event name="controller_action_postdispatch_checkout_cart_add">
        <observer name="test_mymodule_controller_action_postdispatch_checkout_cart_add" instance="Test\MyModule\Observer\ControllerAddToCart" />

and in the observer file, I have the following code:

namespace Test\MyModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Store\Model\StoreManagerInterface;

class ControllerAddToCart implements ObserverInterface
    protected $storeManager;

    public function __construct(
        StoreManagerInterface $storeManager
    ) {
        $this->storeManager = $storeManager;

    public function execute(Observer $observer) {
        var_dump('hello ATC');
        $console = '<script>console.log("action ATC");</script>';
        echo $console;
        $currency = $this->storeManager->getStore()->getCurrentCurrencyCode();
        $consoleCurrency = '<script>console.log("'. $currency .'");</script>';
        echo $consoleCurrency;

I know my module is enabled and it is working fine because I also added the catalog_controller_product_view event and this one is firing.

I have to mention that I've tried the checkout_cart_add_product_complete event, checkout_cart_save_after and checkout_cart_product_add_after. None of these work for me.

Also, not sure if it's relevant to say that I installed the Magento store following the instructions from here and the store has the Luma theme installed.

p.s: I don't see any errors in the console

Thanks in advance to all.

I've tried your code and it ran normally! Please remember to flush the cache after creating any events. Cheer mate!
