Mastering Advanced Laravel: Exploring Queues, Events, Broadcasting, and Horizon 🚀

Understanding Queues 👨‍💻

Queues in Laravel are used to postpone the execution of a lengthy task, such as sending an email, until a later time thus speeding up web requests to your application. Let's see an example of how to implement it.

Firstly, we need to create a new Job. Jobs are the tasks that you wish to queue.

php artisan make:job SendEmailJob

Then we handle the job's logic in the handle() method of our SendEmailJob.

public function handle()
{
    //
}

In the SendEmailJob class, we'd typically have something like this:

class SendEmailJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable;

    protected $details;

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

    public function handle()
    {
        $email = new SendEmailTest($this->details);
        Mail::to($this->details['email'])->send($email);
    }
}

And to push jobs onto the queue, we call the dispatch method on the job itself:

$details['email'] = '[email protected]';
$details['message'] = 'This is our test email';
dispatch(new SendEmailJob($details));

Once we have our queues set up, we can run the queue worker:

php artisan queue:work

And voila! You've just set up your first Laravel queue! 🎉

But what if you want to broadcast events in real-time? That's where Laravel's Event Broadcasting comes into play.

Broadcasting Events 📡

Laravel's Event Broadcasting allows you to broadcast your server-side Laravel events to your client-side JavaScript application. A typical use-case would be updating chats in real time, or showing user notifications.

First, we need to create an Event.

php artisan make:event MessagePosted

And then we implement the ShouldBroadcast interface in our MessagePosted event:

class MessagePosted implements ShouldBroadcast {
    // ...
}
