Laravel Model Events - I'm a bit confused about where they're meant to go

Question

So the way I see it is that a good Laravel application should be very model- and event-driven.

I have a Model called Article. I wish to send email alert

In your case, you may also use following approach:

// Put this code in your Article Model

public static function boot() {

    parent::boot();

    static::created(function($article) {
        Event::fire('article.created', $article);
    });

    static::updated(function($article) {
        Event::fire('article.updated', $article);
    });

    static::deleted(function($article) {
        Event::fire('article.deleted', $article);
    });
}

Also, you need to register listeners in App\Providers\EventServiceProvider:

protected $listen = [
    'article.created' => [
        'App\Handlers\Events\ArticleEvents@articleCreated',
    ],
    'article.updated' => [
        'App\Handlers\Events\ArticleEvents@articleUpdated',
    ],
    'article.deleted' => [
        'App\Handlers\Events\ArticleEvents@articleDeleted',
    ],
];

Also make sure you have created the handlers in App\Handlers\Events folder/directory to handle that event. For example, article.created handler could be like this:

mailer = $mailer;
    }

    public function articleCreated(Article $article)
    {
        // Implement mailer or use laravel mailer directly
        $this->mailer->notifyArticleCreated($article);
    }

    // Other Handlers/Methods...
}
