Livewire Component Not Receiving Broadcasted Laravel Event

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I have set up a Laravel broadcast event using ShouldBroadcastNow and it works perfectly on the front-end with Echo, but my Livewire component never receives the event.

Below are the details:

Event Definition:

PHP
class NewProductAddedToCart implements ShouldBroadcastNow
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public string $idString;

    public function __construct(string $idString)
    {
        $this->idString = $idString;
    }

    public function broadcastOn(): Channel|array
    {
        return new Channel('new_cart_added');
    }

    public function broadcastAs(): string
    {
        return 'add';
    }

    public function broadcastWith(): array
    {
        return [
            'idString' => $this->idString,
        ];
    }
}

Triggering the Event (inside Laravel commands):

PHP
event(new NewProductAddedToCart($idString));

Front-end Listener (Works Correctly):

HTML
<script type="module">
    window.Echo.channel('new_cart_added').listen('.add', (e) => {
        console.log('new_cart_added: TRIGGERED!!', e.idString);
        $('body').find('.jGrowl').attr('class', '').attr('id', '').hide();
        $.jGrowl('A new product has been added to the cart', {
            position: 'top-left',
            theme: 'bg-teal text-white YekanBakhBold'
        });
    });
</script>

Livewire Listener (Not Working):

PHP
class ContentComponent extends Component
{
    #[On('echo:new_cart_added,.add')]
    public function new_cart_added()
    {
        Log::info('SALAM');
    }
}

Despite confirming that the event is broadcast and received on the front-end, the Livewire listener is never triggered. Any insights on what might be preventing the component from receiving the event would be appreciated.

Below is one common cause: the event name you’re referencing in Livewire includes the extra dot. When broadcasting events, your event’s broadcast name is defined in the event class by the broadcastAs() method (e.g. returning "add"). On the front-end you must prefix that with a dot (i.e. listen('.add')), but in Livewire’s #[On()] attribute the event name should be specified without the dot. In other words, change your Livewire listener from:

PHP
#[On('echo:new_cart_added,.add')]
public function new_cart_added()
{
    Log::info('SALAM');
}

PHP
#[On('echo:new_cart_added,add')]
public function new_cart_added()
{
    Log::info('SALAM');
}

This adjustment tells Livewire to correctly listen for the broadcast event on the “new_cart_added” channel with the event name “add” (which is what your event broadcasts as).

Make sure your Livewire component is mounted on the page and that your Echo configuration is loaded; otherwise, the event will not be received by the Livewire listener.
